Mineral wool insulation Isover is made from the earthrsquos

most abundant materials rock sand and minerals of

various types The production is based on fiberizingof molten raw materials consisting of minerals and

different amounts of artificial resins Mineral wool

insulation materials are delivered as wired mats lamella

mats slabs blocks pipe sections and felts Depending

upon the form of delivery mineral wool insulations can

be quilted on wire mesh faced with foils glass fleece or

glass filament tissue or be equipped with coatings

Final Isover products have the following properties

apparent density from 25 to 150 kgm3 (special fire

protection slabs can have density up to 200 kgm 3)

very good thermal insulation performance (low

thermal conductivity)

very good sound attenuation (high absorption

coefficient)

fire resistance ndash non-combustible material

high temperature resistance (possibility of application

up to a maximum surface temperature)

environmental friendly and hygienic

hydrophobisation ndash Isover insulation materials are

made water repellent

long life span (material is not aging)

resistant to wood-destroying pests rodents and

insect

easy to handle easy to cut with a sharp knife

The Isover product range provides fire safe thermal

and acoustic insulation solutions in many applications

including HVAC original equipment transport and

for tanks and storage vessels The range of high

quality products has been designed to be effective in

both performance and cost while providing ease of

installation Each product is engineered to fulfil specific

performance criteria Maximum surface temperature

(MST) is dependent on the apparent density (the

higher the density the higher MST and better thermal

performance at high temperature surfaces) Mineral woolinsulations have a melting point higher than 1000 degC

For outdoor application metal steel jacketing is

required If a product is with an aluminium facing then

the surface temperature must not exceed 100 degC on the

facing proper thickness of insulation must be designed

for this purpose Binders and greasing agents in mineral

wool products dissolve and evaporate in areas with

temperatures higher than 150 degC As the temperaturefalls in the direction of the insulationrsquos cold side the

binder remains unchanged in the greater part of the

material In the outer areas colder than 150 degC no

dissolution and evaporation take place

AS QUALITY

Corrosion of stainless steel surfaces under insulation

is an often discussed issue Highly alloyed austenitic

steel (alloyed by chrome nickel and molybdenum) are

predisposed to tensile stress corrosion (stress corrosion

cracking) which is caused by chloride ions Austenitic

is a description of crystalline steel structure therefore

identified as AS Chlorides with water (well-known

is classical salt) attack steel surface and cause cracks

in the material With increasing surface temperature

the danger of stress corrosion cracking is raised To

minimise this danger mineral wool insulations in AS

quality are available for this application Standard AGI

Q 132 determines maximum content of chloride ions of

10 mg in 1 kg of the insulation material Mineral woolinsulations may be used for insulating objects made

of stainless austenitic steels if the content meets the

requirement Isover stone wool technical insulations

meet the requirement of AGI Q 132

THERMAL CONDUCTIVITY

One of the most important parameters of insulations is

their thermal conductivity named lambda value λ [W

(mK)] Thermal conductivity measures the capacity of a

material to lead or to resist heat transfer The smaller

the lambda value the better the thermal insulation

The thermal performance of mineral wool is achievedthrough the entrapment of air within the material Its

thermal conductivity does not deteriorate over time

For slabs mats felts and loose mineral wool the

thermal conductivity is determined in the hot box

tester according to EN 12 667 The determination of the

thermal conductivity of sections is in the pipe tester

according to EN ISO 8497 For lamella mats and wired

mats the thermal conductivity is measured in the hot

box and in the pipe tester The thermal conductivity of

mineral wool insulations has to be determined up to the

maximum service temperature (hot face) as a function

of the mean temperature (arithmetic mean betweenobject and surface temperature)

The thermal conductivity varies with temperatures and

with densities The higher the density the higher the

thermal performance at high temperature surfaces In

our product data sheets declared lambda-values λD

are

used these values are fulfilled within every product

A designer will be on the safe side when using our

declared lambda-values That means allowances for

workmanship spacers and supporting constructions

are made Possible inaccuracies caused by calculation

equations can be eliminated

MELTING POINT OF MINERAL WOOL

PRODUCTS

The melting point of mineral wool is determined

according to DIN 4102 part 17 It is a parameter for

the durability of mineral wool insulations in building

components in case of fire It must not be confused

with the maximum service temperature and has no

relation to the service temperature Mineral wool

insulations have the melting point higher than 1000 degC

usually in the range from 1200 to 1600 degC

MAXIMUM SERVICE TEMPERATURE

Maximum service temperature according to EN 14 706

(for wired mats lamella mats and slabs) and EN 14 707

(for pipe sections) ranging from 250 to 700 degC MST for

various products can be found in a Product data sheet

or at the end of the catalogue in the chapter Isover

Products on page 23

FIRE RESISTANCE

Mineral wool products Isover are completely non-

combustible they resist to high temperatures and thus

prevent fire spread The classification levels according

to EN 13 501-1 are A1 possibly A2 for materials with

a facing

ACOUSTIC PROPERTIESIsover mineral wool products have a fibre structure

and therefore reach excellent noise attenuation for

example from HVAC services (pipework ductwork

and air handling equipment) and other services An

absorbent layer of mineral wool has the best absorption

capacity in the medium and high frequencies (under

such conditions it can have absorption coefficient up to

98 (α = 095)) The absorption in the low frequencies

is improved by increasing the thickness or by providing

an air gap behind the absorbent layer

RESISTANT TO BIOLOGICAL PESTSMineral wool insulation is resistent to wood-destroying

pests rodents and insects They are rot-proof and do

not sustain growth of mould

LOW THERMAL EXPANSION

Mineral wool insulations have almost zero thermal

expansion with changing temperatures

MOISTURE AND WATER REPELLENCE

All Isover products are treated during manufacture with

special additives which make them water repellent

Isover products are a hydrophobic non-hygroscopicinsulation material If Isover products get wet they

dry out quickly as a result of the open structure and its

mechanical and insulating properties are unaffected

after drying For outdoor application metal steel

jacketing is unconditional ly required

BASIC FUNCTIONS OF TECHNICAL INSULATIONS

Insulations are defined as those materials which retard

the flow of heat energy by performing one or more of

the following functions

Energy conservation minimizing unwanted heat loss

gain from building HVAC systems as well as preserv-

ing natural and financial resources

Personnel protection controlling surface tempera-tures to avoid contact burns (hot or cold) ndash maximum

surface temperature criterion

Condensation control minimizing condensation by

keeping the surface temperature above the dew point

of surrounding air

Prevent internal condensation in pipes

Process control minimizing temperature change in

process fluids where close control is needed

Increase operating efficiency of heating ventilating

cooling plumbing steam process and power systems

found in commercial and industrial installations

Freeze protection minimizing energy required for

heat tracing systems andor extending the time to

freeze in the event of system failure Freeze protec-

tion of vessels and tanks with various accumulated

fluids or fuels

Noise control reducingcontrolling noise in mechani-

cal systems

Fire safety protecting critical building elements and

slowing the spread of fire in buildings

The application of thermal insulation on pipe vessels

and ducts is recognized as a necessary requirement in

any construction activity The thickness and extent of

insulation required has always been subject to arbi-

trary and imprecise decisions with little engineering or

economic input No material incorporated in a modern

construction project provides the owner with as good

a financial return throughout the life of the facility as

does insulation

The investment in insulation may protect the equip-

ment and personnel present during the life of the facil-

ity Proper insulation prevents condensation chemical

corrosion and excessive heat in fire hazard areas Added

human comfort provided by proper insulation in hotelsoffice buildings schools or factories adds considerably

to the value of the facility and productivity of its per-

sonnel Process temperatures in heat traced piping are

more efficiently maintained with proper insulation The

size of the heat generating equipment can be reduced

when designed with an efficient insulation system In

some cases insulation is essential to an industrylsquos very

existence as with the power the process and

the cold storage

However the most substantial return on an investment

in insulation is in energy savings over a period of timeThese savings are becoming more and more empha-

sized in the industrial insulation field as energy costs

rise coupled with the fact that industrial plants and

utilities usually account for about half of the total en-

ergy consumption

Recently the environmental impact of new renovated

or relocated industrial and commercial facilities has

taken on new importance Thermal insulation is one of

the most if not the most significant technology used

to conserve energy thereby reducing pollution Besides

minimizing heat loss insulation increases process ef-

ficiency helps maintain employee safety comfort and

production

For their thermal protection of various industrial appli-

cations it is a necessity to design and use such insula-

tion material that meet operating conditions Isover will

help you find the most suitable insulation product for

given application

HEAT FLOW TRANSMISSION

Heat transfer is carried out by three heat transmission

modes conduction convection and radiation

Conduction

Heat transfers from warmer surface to colder through

solid material or gas (by fibres in mineral wool

insulations) The more insulant the material the less

the conduction

Convection

Transfer of heat caused by air movements (because of

temperature and density gradient) Hot air moves up

and heat dissipates The quieter the air the less the

convection Convection can be natural (when calculating

insulation inside the building) or forced (for calculation

outside where wind blows)

Radiation

Each material absorbs or emits thermal radiations

depending on its temperature and its emissivity Unlike

conduction or convection heat can be transferred by

radiation also in a vacuum When radiation is absorbed

or reflected there is less thermal transfer Measure of

radiating capacity of a material is emissivity ε Absolute

black body has the highest emissivity (ε = 1) Rough

and dark surfaces approaches such value (for example

mineral wool insulation without jacketing ε = 094)

contrary to bright and smooth surfaces that have very

low emissivity (for example polished aluminium foil ε

= 005) For design it is necessary to take into account

that covering of the bright surface with dust will

increase emissivity significantly

These three transport mechanisms are applied in

two very important quantities ndash surface heat transfer

coefficient α and thermal transmittance U

Thermal insulations impede conduction convection and

radiative effects

by creating a thermal barrier against conductionby suppressing air movements

by limiting radiative effects

Surface heat transfer coefficient

Two heat transmissions (convection and radiation)

influence the heat transfer coefficient α [W(m2middotK)] The

higher the heat transfer coefficient the higher the heat

flow rate from a warm surface

Thermal transmittance

Thermal transmittance (also called Overall heat transfer

coefficient) U (for flat surfaces [W(m2middotK)] for pipes [W

(mmiddotK)]) is inverted value of thermal resistance and it

takes into account the influence of all heat transmission

modes (conduction convection and radiation)

INSULATION SYSTEM DESIGN

GENERAL

An insulation system is the combination of insulations

finishes and application methods which are used toachieve specific design objectives Among these are

Energy savings

Reduced operating costs

Condensation control

Chemical compatibility with the metals being

insulated the atmosphere to which the system

will be exposed and the various components of the

insulation system itself

Protection of mechanical and insulation systems

from mechanical abuse and atmospheric damage

Personnel protection

Fire protection

Sound control

Future requirements for access to piping fittings etc

Accommodation to limited clearances or work space

While there are several choices of insulation materials

which meet basic thermal and cost-effective

requirements of an installation choices become more

limited with each additional design objective that

comes into play

INSULATION THICKNESS CALCULATION

When calculating the thickness of the insulation it isessential to put in appropriate boundary conditions lt

should be noted that the steady-state calculations are

dependent on boundary conditions Often a solution

at one set of boundary conditions is not sufficient to

characterize a thermal system which will operate in a

changing thermal environment (process equipment

operating year-round outdoors for example) In such

cases local weather data based on yearly averages or

yearly extremes of the weather variables should be

used for the calculations

The heat flow through a surface at any point is a function

of several variables which are not directly related

to insulation quality Among others these variables

include ambient temperature movement of the air

roughness and emissivity of the heat flow surface and

the radiation exchange with the surroundings (often

including a great variety of interest) For the calculation

of dew formation variability of the local humidity is animportant factor

Insulation desigh criterion

Apart from a choice of suitable insulation material

for given application it is essential to design proper

insulation thickness It can be determined from two

points of view

Heat loss minimalisation it means reaching the highest

possible economic savings (ideally to calcutate economic

insulation by so- called optimalisation)

Maximum surface temperature (personal protection

against burn) It is usually prescribed by nationallegislation Usual maximum surface temperature is

50 degC if the surrounding air temperature is 25 degC If the

air temperature is different temperature difference

between surface and surrounding air should be up to

25 degC Outdoor piping shall be controlled for maximum

surface temperature every time for summer period

(in the Central Europe calculation air temperature is

30 degC) In boiler rooms surrounding air temperature is

minimally 35 degC

Parameters influencing insulation thick-

ness designHeat flow from the insulation surface is a function of

several parameters which do not relate directly to the

quality of the insulation Here are several parameters

that influence design

thermal conductivity of the insulation material

medium temperature

ambient temperature

external heat transfer coefficient

ECONOMIC THICKNESS

The most substantial return on an investment ininsulation is in energy savings over a period of time

Thermal insulation is one of the most if not the most

significant technology used to conserve energy thereby

reducing pollution Rising energy costs guarantee an

increasing return on any investment made in insulation

In fact it costs less to insulate than not to In the case

of steam process and heat the difference in capital

investment necessary to provide equipment for the

extra steam capacity needed on underinsulated systems

and that investment necessary to insulate plus the

cost of insulation still represents a significant capital

investment savings That insulation saves money is not

the issue here The issue is how much

8122019 Catalogue of Technical Insulations 2013-10-598 En

httpslidepdfcomreaderfullcatalogue-of-technical-insulations-2013-10-598-en 828

Economic thickness calculations are based on the law

of diminishing returns Because no insulation material

can completely stop the flow of heat each increment ofinsulation added to the thickness saves only a percentage

of the heat which has escaped through the underlying

insulation Therefore each increment of insulation

saves less than the one before it and must be evaluated

against the cost of installation to determine if it is a

ldquogood investmentrdquo It is possible to determine how much

insulation applied to a given system will repay its initial

costs in a specified time This point is reached when the

cost of the last incremental of insulation added is offset

by the savings generated by that increment

Refer to the stetch on the left The vertical scale is the

annual cost The horizontal scale is insulation thickness

As the insulation thickness increases from 0 the cost of

heat loss through the insulation decreases Note that this

cost (line B) tends to approach a horizontal line at high

thicknesses As the insulation thickness increases the

cost of the insulation also increases (line A) The total

annual cost at any insulation thickness is the sum of the

cost of the insulation and the cost of the lost heat (line

C) Line C goes through a minimum value of total annual

cost at the Economic thickness

With thicknesses less than the economic thickness the

total annual cost is higher because of the higher valueof the cost of lost heat With thicknesses higher than

the economic thickness the total annual cost is higher

because of the higher value of the cost of the insulation

In the case of computer results each pipe size will be

listed with the recommended thickness as well as

the average heat savings (as compared to a pre-listed

thickness or bare surface whichever chosen) and the

present value of the heat saved

In order to use any of the available manuals tables

or computer programs the two cost factors (cost of

lost energy and cost of insulation) must be found Thefollowing data is generally provided by the investor

Cost of lost energy

This factor is derived from the combination of the

rate of energy transfer the cost of energy and the

operational hours per year of the building Computing

the rate of energy transfer requires surface and

ambient temperatures thermal conductivity of the

chosen insulation the maximumminimum thickness of

insulation to be considered surface emissivity and last

but not least consideration of surface orientation (i evertical horizontal) and wind (air) velocity

Cost of insulation

This factor is derived from computing a bdquounit installed

price of insulationldquo with the total cost annualized overthe projectacutes life The unit installed price is a combination

of the cost of materials cost of labor and worker

productivity This is a sensitive variable in the economic

thickness calculation Only the roughest of regional

averages are available As a result care must be taken not

to perceive these estimates as fixed budget prices used

for installing insulation Material prices are related to the

volume and cost of the insulation jacketing securement

finishing and structural support material used Also

included in this figure are storage and handling costs to

the contractor Labor costs vary regionally and include

wages fringe benefits per diem and travel expensesas well as overhead and profit Labor production varies

with pipe size complexity number of layers necessary

accessibility of piping and surfaces type of materials

used and general working conditions Other costs

involve the job size and increase with the magnitude of

the job They include the preparation scaffolding clean-

up and tear-down costs supervision costs and general

overhead

ISOCALreg

For economic thickness calculation program IsoCal

can be used The program also handles the followingcalculations

heat loss calculation

temperature change in pipes or ducts

temperature change in a tank

internal or external condensation

frost protection of water pipes

sound attenuation in ducts

IsoCalreg is a computer program for calculations of

thermal insulation for building equipment and

industrial installations The program mainly calculates

according to EN ISO 12 241 IsoCalreg has been developedprimarily for Saint-Gobain Isoverrsquos range of insulation

products it is however possible to perform more

generic calculations For more information about the

representative

MAXIMUM SERVICE TEMPERATURE

MST is determined in a laboratory by testing under de-

fined conditions which are dependent upon the form

of delivery and which are laid down in EN 14 706 (for

wired or lamella mats slabs and felts) and EN 14 707(for pipe sections and segments) MST is determined

by establishing the temperature and time related de-

crease in thickness in one-sided heating For the test

the sample shall take a load of 500 Pa The sample is

heated with a transient of at least 5 Kmin The hot-

face temperature must be maintained for 72 hours at

the expected maximum service temperature At the

maximum service temperature no test result must dis-

play a deformation under load of more than 5

In data sheets of different producers (not only mineral

wool) you will often find MST and value which is not

measured accordance to EN 14 706 This temperature

is only assumed When using such temperature there

is a danger of insulation degradation mainly insulation

thickness If mineral wool product has MST 700 or 750 degC

in its data sheet you can be sure that the material will

not withstand such temperature without degradation

of assessed properties Such temperatures shall not

be used Producers should leave field of assumed MST

and test their products to be able to use declared

MST according to EN 14 706 It is an outstandingimprovement compared to the past because individual

products on the European market can be compared to

each other according to standards valid in the EU

Slabs wired and lamella mats Orstech are certificated

according to valid European standards they are

regularly tested in testing laboratory FIW Muumlnchen

according to VDI 2055 and AGI Q 132 Maximum service

temperatures for various products can be found at the

end of the catalogue in the chapter Isover Products on

page 21)

EVAPORATION OF BINDERS

Binders and greasing agents in mineral wool products

dissolve and evaporate in areas with temperatures

higher than 150 degC Binder evaporation does not have any

influence on thermal properties only the compactness

of a material is decreased If proper underconstruction

is made there is almost no danger of insulation slide

down But if too small insulation thickness or improper

type of insulation is used (mostly insulation with too

low density for too high temperatures) danger of binder

evaporation in the whole thickness is possible with

consequent insulation slide down In this case no well

made underconstruction will help Insulation will not

work any more In the outer colder areas no dissolution

and evaporation take place

Density influence on thermal conductivity

Temperature influence on thermal conductivity for slabsORSTECH

FIRE PERFORMANCE

FIRE ndash a chemical reaction involving rapid oxidation or

burning of a fuel occurs only when three elements are

present in the proper conditions and proportions

FUEL ndash Fuel can be any combustible material - solid

liquid or gas Most solids and liquids become a vapour

or gas before they burn

OXYGEN ndash The air we breathe is about 21 oxygen Fire

only needs an atmosphere with at least 16 oxygen

HEAT ndash Heat is the energy necessary to increase the

temperature of the fuel to a point where sufficient

vapours are given off for ignition to occur

Fire development depends mostly on room geometry

and ventilation the fuel type the amount and surface

area of the fuel Fire is often discussed in terms of the

temperature development and can be divided into

different stages incipience (ignition) growth flashover

fully developed fire and decay

How materials behave in the early stages of a fire from

ignition to flashover (the spontaneous ignition of hot

smoke and gasses) needs to be assessed at the design

stage for buildings and also for plants and equipment

Euroclasses a new European harmonised classification

system for materialsrsquo reaction to fire in most Europeancountries replaced the old national standards The

Euroclass fire classification covers not only materials

used in building structures but it is being extended also

to technical insulations to cover building equipment

and industrial installations This will help to compare

the reaction to fire of different thermal insulation

materials

The classification levels are A1A2 (completely non-

combustible) B C D E and F A1A2 corresponds to

the safest situation E would be the most dangerous

situation and F would mean not classified

ISOVER mineral wool insulations are totally non-

combustible and completely fire safe achieving

Euroclass A1 fire rating (A2 for products with facing)when classified in accordance with EN 13501-1 One

of the most important issues studied under reaction to

fire performance is the potential for flashover to occur

which can lead to a fire spreading uncontrollably Isover

stone wool is not susceptible to flashover

This is a guide to common building materials and their

likely Euroclassification

Check with individual product manufactures for spedific

product specifications

REACTION TO FIRE

Smoke and flaming droplet risk(1) In the EU classification system for reaction to fire

a construction product will be classified as Euroclass A1

A2 B C D E or F depending on its tendency to burn

(2) The product testing will provide data represented

by the signs s1 s2 or s3 which indicate the tendency

to release smoke Smoke causes over 60 of deaths in

fire across the EU The measurement of smoke release

has been put into these 3 broad bands that can be

translated as ldquolittle or no smokerdquo s1 - rdquoquite a lot of

smokerdquo s2 - rdquosubstantial smoke releaserdquo s3

(3) Some construction products like these made of

polystyrene can melt and ignite to form Flaming

Droplets Wooden products on the other hand will tend

to char before the char falls away as Flaming Particles

to expose more material

These rdquoflaming dropletsparticlesrdquo will tend to

initiate new fires away from the original point of

ignition and must be considered when the products

are used horizontally in ceiling or roof applications

The classification system ranks the level of release of

flaming dropletsparticles as d0 (none) d1 (some) and

d2 (quite a lot)

FIRE PROTECTION DESIGN FOR VENTILATION DUCTS

Produced with the stone wool technology of Isover

fire protection system ORSTECH Protect is mineral

wool that combines all the advantages of conventionalthermal and acoustic insulation with top level of fire

safety Mineral wool insulations have the melting point

higher than 1000 degC From the fire protection point of

view products Isover are one of the safest materials

ORSTECH Protect consists of slab or lamella mat

solutions offering up to one hour fire protection for

both vertical and horizontal applications of rectangular

and circular ductwork systems

Passive protection of ventilation ducts is possible by

two basic means

Installed a fire damper into the duct to the place of

fire separation

Use a fire protection insulation system which is

tested according EN 1366-1 and has a classification

protocol in accordance with EN 13 501-3 This second

case is covered by insulation system ORSTECH

Protect

LEGISLATION

Air duct which shall resist the spread of fire from one

compartment to another is tested according to EN

1366-1 The standard can be applied to vertical and

horizontal ducts with or without branches for fire inside

or outside the duct The test measures the time period

for which ducts of specified dimensions suspended as

they would be in practice satisfy criteria when exposed

to fire from inside or outside (separately)

This standard is used in conjunction with EN 1363-1

which prescribes requirements for the determinationof fire resistance of various components of building

structures which are exposed to standard fire

conditions In this standard there are failure criteria

whereby it is possible to evaluate the ability of a tested

duct to prevent fire spread due to the destruction of

the duct (integrity failure E) heat transfer (insulationfailure I) and prevention of the smoke penetration

(smoke leakage S) Fire protection is expressed by time

in minutes for which failure criteria are fulfilled

Designation itself is then done according to

classification standard EN 13 501-3 Classification

states if criteria are fulfilled for fire outside (marking

o rarr i) valid for duct type A or fire inside (marking

irarr o) or from both directions (iharr o) valid for duct type

B and if this is valid for a horizontal duct (marking ho)

or a vertical one (ve) or both (ve ho) Eg class bdquoEI 30 S

ndash ve ho (orarr i) Sldquo represents duct capability to maintain

integrity insulation and smoke leakage for time period

of 30 minutes under fire exposure from outside both

for vertical and horizontal positions

MAXIMUM DUCT SIZES

Maximum size is according to EN 1366-1 for rectangular

duct 1250 x 1000 mm and for circular duct up to

diameter 1000 mm If a duct has bigger dimensions the

ACOUSTIC PERFORMANCE

Noise is a sound which impacts negatively on the

surroundings Noise levels emanating from HVAC

services (pipework ductwork and air handlingequipment) and other services can be significantly

reduced with the use of Isover products which will

help to achieve acceptable environmental noise levels

Isover insulations are due to its fibre structure an ideal

material for sound attenuation not only for industrial

application The degree of sound insulation will depend

upon the application the thickness of insulation used

and the nature of any finish used to clad over the

installation In suitable frequencies they can absorb up

to 95 of the sound energy (α = 095)

SOUND ABSORPTIONWhen a sound wave strikes a surface the sound energy

is broken down into transmitted energy (through the

material) converted energy (usually heat) and reflected

energy (back towards the source of the sound)

The more absorbent the material the less sound is

reflected That part of sound energy which is converted

and transmitted is usually expressed as an absorption

coefficient α

The absorption coefficient for a material varies with

the frequency An absorbent layer of mineral wool

has the best absorption capacity in medium and high

frequencies The absorption in low frequencies is

improved by increasing the thickness or by providing an

air gap behind the absorbent layer

Examples of the effectiveness of Isover products in noise

control are given in the following table

ABSORPTIVE STRUCTURES

The most common task in room acoustics is to attenuate

or cancel some frequencies or a whole frequency band

This is possible to realise by using convenient absorptive

material or structures which are frequency-dependent

In this way we can control not only absorption ie

reverberation time but also suppress or completely

remove unpleasant sounds

In a porous material acoustic absorption is mainlycaused by friction in pores ie friction between

oscillating particles and the surface of pores Since the

energy loss due to friction is proportional to the length

of the path the most absorption will occur when the

porous material is placed in a position where the particle

displacement is the largest (maxima displacement)

When sound strikes a rigid wall like concrete for

example a standing wave result and the maxima of

particle displacement appear at the distances λ14

3λ24 5λ

34 hellip from the surface of a room These are the

critical distances which must be covered by adsorbers

ie layers with thicknesses d1 = λ

14 d

2 = 3λ

24 d

3 = 5λ

34

In short an absorber with a thickeness d placed directly

on the solid structure will effectively attenuate only

those frequencies where f ge c4d (c is the velocity of

sound 340 ms) For example insulation thickness

of 50 mm wil l reliably attenuate frequencies higher

than 1700 Hz thickness 100 mm then already from

frequencies 850 Hz The higher the frequency the

shorter the wave length and better attenuation

An absorbing layer tightly adjacent to a solid structure

has nevertheless one disadvantage To attenuate

low frequencies it would be necessary to use verythick layers (for example for attenuation of 500 Hz a

thickness of about 20 cm would be necessary) Therefore

acoustic tiles can hardly attenuate low frequency noise

(frequencies lower than 100 dB such as noise from

discotheques)

Fortunately it is possible to avoid expensive acoustic

tiles with high thickness If we use a very thin layer

and place it just in the position of the displacement

maximum of a chosen frequency this chosen frequency

and its odd multiples will be attenuated Acoustic

tiles thus work as a selective frequency filter On theselective basis also other acoustic attenuators work

namely membranes oscillating plates and resonators

ACOUSTICS INSULATIONS

Isover stone wool products with a high longitudinal air-

flow resistance (up to 95 kPasm2) and uniform porosity

(93 ndash 99 ) are used as sound attenuation insulations

In suitable frequencies they can absorb up to 95 of

the sound energy (α = 095) Sound attenuation in a

construction is related to elastic properties of Isover

mineral wool insulations and their low modulus of

elasticity (they have low dynamic toughness and

therefore they are much more suitable for acoustic

purposes in comparison with foam plastics)

Sound attenuation properties of Isover products are

characterised by an absorption coefficient α which

can be found in the table for three thicknesses andsix frequencies According to a given noise spectrum

it is possible to design a sound attenuation structure

of which our material is only a part Since we provide

only insulation material we launch only absorption

coefficients Final attenuation will be dependent on

the whole designed construction (considering also

supporting construction hangers) and assembly

Isover does not design sound attenuation and thus it

is necessary to ask specialists who are able to design a

proper structure

Generally we can say that transmission loss is higher

for constructions with higher plane weight therefore

in most cases insulation with higher density has

better sound attenuation (eg slabs Orstech 65 90

110 Isover FireProtect 150) than insulation with lower

density (eg Orstech 45) Slabs can be manufacturedwith a facing ndash glass black tissue

GENERAL RULES FOR USING ISOVER INSULATIONS

Between insulated piping sufficient distances must

be kept

Valves should be placed without needing to go on theinsulated pipes when handling them

Spindle of valves should not be installed in an upward

direction to avoid water leakage into the insulation

Surfaces before insulating must be clean and dry It

is not possible to insulate wet or frostbitten surfaces

which may later cause damages of insulation or

insulated surfaces

Dirt and rust must be rubbed down from untreated

carbon steels

Smear and oils must be removed by detergents or

solvents from insulated surfaces

Stainless steel surfaces must not be cleaned by

detergents or solvents with chloride content They

may be cleaned only by stainless steel brushes

Chloride solution attacks stainless steel surface and

causes stress corrosion cracking in the material With

increasing surface temperature the danger of stress

corrosion cracking is raised

Piping and equipment from stainless steel can be

insulated only by mineral wool insulation in AS

quality Such material can have maximum content

of chloride ions of 10 mg in 1 kg of the insulation

material

It is necessary to avoid contact of metals which can

cause galvanic corrosion (Cu-Zn Fe-Al)For operating temperatures higher than 600 degC

aluminium jacketing should not be used

Self-tapping screw bold or rivet should be from the

same material as the jacketing

Surfaces with temperatures higher than 500 degC

should be insulated by more insulation layers in a

way that each layer has a different apparent density

Material with higher density insulates better under

higher temperatures than material with lower

density therefore insulation with higher density is

placed closer to the hot side Under low operating

temperatures thermal performance is almost equalSafety working principles must be kept for insulation

assembly

Isover products are packed into PE foil They must be

transported in covered vehicles under such conditions

to avoid moistening or other degradation They must

be stored in covered places

Wired mats

After the cutting of needed length the wired mat shall

be tightly wrapped on the pipe Wired matsrsquo butt jointsshould be in close contact to each other to ensure no

gaps between mats For multiple layer construction

each layer is staggered when applied Each layer must

be secured in place before the next is applied Individual

mats are bound together with a wire with minimal 07

mm thickness Alternatively wired hook or stainless

steel bands (with minimum width of 10 mm) can be

used Maximum distance between hooks is 150 mm

The decision to use multiple layers may be made for one

or more of the following reasons

to provide compensation for pipe expansion andcontraction

to reduce heat flow by staggering joints thus creating

a more thermally efficient installation

to achieve thickness in excess of manufacturersrsquo

capabilities

for retrofitting purposes

Lamella mats

Lamella mats Orstech LSP H consist of mineral wool

lamellas which have been glued to aluminium foil

reinforced with a glass fibre grid and these fibres are

predominantly perpendicular to the surface of themat Compressive strength but thermal conductivity

too are increased compared to mats with a fibre

orientation parallel to the surface (wired mats) Due

to its compressive strength resistance they have less

demands for undeconstruction (less thermal bridges)

in comparison with wired mats Temporary securing in

place is done by aluminium tapes final fixing shall be

done by a baling wire

Protective coverings

The efficiency and service of insulation is directly

dependent upon its protection from moisture entry andmechanical and chemical damage Choices of jacketing

materials are based upon the mechanical chemical

thermal and moisture conditions of the installation

as well as cost and appearance requirements The

basic function of the weather protection is to protect

the insulation from rain snow sleet wind solar

radiation atmospheric contamination and mechanical

damage With this definition in mind several service

requirements must be considered

PIPING INSULATION

For domestic hot water piping with smaller diameters

insulation pipe sections which are covered withaluminium foil are ideal Pipe sections with a facing

have a self-adhesive overlap in a longitudinal joint

to ensure perfect enclosure of a pipe section It is

recommended to secure pipe sections by an aluminium

tape or by galvanized wire transversely They are usually

knotted three times per meter more for pipe sections

with higher diameter Higher diameters should be

secured either by wire or by metal band (at least two

bands per meter)

Pipings with bigger diameters are most commonly

insulated by lamella mats Orstech LSP (stone woolinsulation) or Isover ML-3 (glass wool insulation)

eventually by wired mats Orstech DP (especially for higher

temperatures) Lamella and wired mats are also suitable

for appliances and vessels (both ends and cylindrical

parts) residential heating systems and air ducts

Internal mechanical forces ndash expansion and contraction

of the pipe or vessel must be considered because the

resulting forces are transferred to the external surface ofthe weather barrier Ability to slide elongate or contract

must be provided

External mechanical forces ndash mechanical abuse (ie

tools being dropped abrasion from wind-driven sand

personnel walking on the system) inflicted on a pipe or

vessel needs to be considered in design This may affect

insulation type as well as the weather barrier jacketing

type

Chemical resistance Some industrial environments may

have airborne or spilled corrosive agents that accumulate

on the weather barrier and chemically attack the pipe or

vessel jacketing Elements that create corrosive issues

must be well understood and accounted for Insulation

design of coastal facilities should account for chloride

attack

Galvanic corrosion Contacts between two different

types of metal must be considered for galvanic corrosion

potential Similarly water can act as an electrolyte and

galvanic corrosion can occur because of the differentpotential of the pipe and vessel and a metal jacketing

Materials used as weather barriers for insulation

Typical metal jacketing materials bare aluminium coated

aluminium stainless steel painted steel galvanized steel

aluminium-zinc coated steel

Typical polymeric jacketing materials polyvinyl chloride

(PVC) polyvinyliedene chloride (PVDC) polyisobutylene

multiple-layer composite materials (eg polymericfoil

mesh laminates) fabrics (silicone-impregnated fibreglass)

Fittings valves

Insulation of fittings valves flanges and couplings is

the most time consuming and often expensive aspectof commercial and industrial insulation But it is crucial

to insulate also these parts properly otherwise most of

energy will be transported by these thermal bridges For

example for 200 degC medium heat loss of one uninsulated

valve corresponds to one meter of uninsulated pipe or

ten meters of uninsulated pipe

Fittings are items used to change size direction of flow

level or assembly of piping They may be of the screwed

sweat or welded types Valves are any of various devices

that regulate liquid or gas flow and they may be of the

screwed sweated flanged or welded types Flanges areprotruding rims and edges of the screwed or sweated

type used with fittings valves couplings etc And finally

mechanical couplings are devices used in assembly of

piping Screwed and flanged connections on fittings

valves couplings etc usually require oversized insulation

applications to compensate for the protrusions

Minimum spacing between pipes and

constructions

It is essential to ensure sufficient space between pipies

and between a pipe and a wall (minimally 100 mm)

Otherwise there is a great danger of creating a zone withalmost no cenvenction The result can be too high surface

temperature (needed personal protection against burn)

or possibility of condensation on cold piping Besides

mounting would have been more difficult

DUCTING INSULATION

Isover products are designed to provide high levels of

thermal acoustic and fire protection insulation in HVACductwork applications such as rectangular flat oval and

circular ductwork

The most suitable insulation materials for ducts are

felts KLIMAROL with aluminium foil facing lamella mats

Orstech LSP or Isover ML-3 wired mats Orstech DP or

slabs Orstech H with aluminium foil facing

Duct insulation mounting

Insulation is mostly fixed to the duct by welded pinsWhen using Orstech H slabs with aluminium facing all

the joints shall be sealed with aluminium tape If a steel

clamping band is used it is necessary to use thin-walled

steel L-profiles to avoid trimming of the insulation If

using Orstech slabs without aluminium facing or Orstech

FIRE PROTECTION OF VENTILATION DUCT

Description

It is vital to develop safe durable and reliable solutions

for ventilation systems as fire can easily spread from the

point of origin via ductwork Isover meets the highest

standards for fire protection providing excellent fire

resistance and top-rated reaction to fire performance

Rectangular ducts shall be insulated by Orstech 65 H

slabs with 40 mm thickness (60 mm for fire resistance EI

60 for a horizontal duct) circular ducts shall be insulated

by Orstech LSP PYRO lamella mats with 50 mm thickness

By these solutions fire resistances EI 15 30 45 and 60 S

have been certified to comply with EN 1366-1

Orstech system with fire resistance has been proven to

meet the requirements of all possible scenarios for fire

from the outside The scenarios can be identified by duct

orientation and duct shape (see table below) Horizontal

ducts normally serve one floor of a building Vertical

ducts normally serve between floors of a building All

scenarios have been done only with one layer Insulation

is fixed to a duct by welded pins Such solution is time

and material saving

Metal ductworkThe steel duct is constructed in sections of galvanised

steel sheet or stainless steel sheet minimum 08 mm thick

(standard duct sheeting for rectangular ducts specified

in DIN 24190 for circular ducts in DIN 24145) Maximum

duct size for which classification protocol is valid is 1250

mm (width) x 1000 mm (height) for rectangular duct or

diameter up to 1000 mm for a circular duct

At each cross joint flanges are fastened to the duct

with spot welds at 150 mm nominal centres

Use a ceramic tape gasket and fire-stopping mastic

between the flanges to seal the joints

Flanges are bolted together with an M10 steel nut

and bolt at each corner

Fasten the flanges together with steel clamps with

bolts M8 (see the figure) in quantity of 3 clamps per 1

meter of the flange length

Drop rods and hangers

Rectangular ducts are suspended by threaded rods and

channel section bearers A duct shall be hung with asuspension system which is independently fire rated

according to EN 1363-1 Certificated suspension system

MUPRO is recommended for the purpose Each steel

hanger consists of two threaded drop rods minimum

M10 and a channel section bearer 3840 mm Fasten

the bearer to the drop rods using hexagonal nuts and

washers The drop rods can be positioned either inside

the insulation material or outside If drop rods are outside

there is no need to insulate them separately The bearers

are positioned inside the insulation material

Circular ducts are suspended by MUumlPRO steel hangerswhich consist of two threaded drop rods minimum

M10 and a two-part industrial circular band The ends

of each band section are bent outwards Fasten the band

sections together and attach them to the drop rods with

hexagonal nuts and washers Place these hangers inside

the insulation The rods do not need to be protected by

insulation

When fixing them to a concrete construction use all-

steel expanding anchors to fasten the threaded rod

hangers to concrete soffits The anchors should penetrate

the concrete by at least 60 mm When fixing to a steel

supporting construction drill a hole through the steel

member allowing the drop rod to be supported by a steel

nut and washer above If a clamp type fixing is used the

clamp must be steel suitable for the purpose It should

pass around the steel member and be fastened back on

itself Clamps that rely on friction to hold them in place

are not suitable

Insulation

Rectangular ducts are insulated by Orstech 65 H slabs

(with apparent density 65 kgm3 and with one-sidedaluminium foil facing) with 40 mm thickness (60 mm

for fire resistance EI 60 for a horizontal duct) Circular

ducts are insulated by lamella mats Orstech LSP PYRO

with 50 mm thickness Insulation slabs (lamella mats)

need to be cut to fit the duct as tightly as possible the

insulation may need to be cut to fit around flanged duct

joints Install the insulation so that one slab (lamella

mat) is adjacent and tightly fitted against the other No

gaps must be present between butt joints of insulation

Insulation can be easily cut with a standard laggers knife

There is no need for adhesive on joints All the joints shall

be sealed by aluminium tape For rectangular ducts in theposition of flange the slabs are snick first 15 mm of the

thickness to avoid lifting of the slabs Butt joints should

be positioned out of flanges Fire protective insulation for

circular ducts does not require usage of a wire net mesh

on the outer side of insulation

Stud welded pins

The insulation is fixed to the duct using steel pins 27 mm

to 3 mm nominal diameter and spring steel washers

minimum 30 mm diameter The length of pin should

be equal to the insulation thickness The orientational

number of pins is 16 piecesm2 for rectangular ducts and14 piecesm2 for circular ducts

Recommended distance from duct edges and joints is

80 mm 50 mm from flanges

Wallfloor penetration

At wallfloor penetration one must insure the same fire

resistance of ventilation duct as has the fire separation

to avoid the spreading of fire from one compartment to

other via a duct This is possible by two basic principles

or their combinations - install a fire damper at the

penetration point or use insulation with fire resistancewhere the crucial thing is the fire-stopping The fire-

stopping is from the second insulation layer with the

width of 150 mm from both side of fire separation

The same general principle is used for both rectangular

and circular ducts regardless of orientation Place

the duct in the penetration of the construction with

approximately 10 mm gap between insulated duct and

opening Before installing the fire-stopping with the

same insulation thickness as is used for the first layer

pack the space between the duct and partition with

as many pieces of insulation as possible Ensure tight

compression in order to completely fill the opening This

must be done because system ORSTECH Protect does

not require stiffeners inside the duct Then install thesecond insulation layer so that it is adjacent and tightly

fitted against the penetration The insulation must be

cut leaving excess length so that it exerts some pressure

between the penetration and the last fitted piece of

insulation

The second layer is fixed by welded pins with length

equal to double insulation thickness The second layer for

circular ducts (lamella mats) is clamped with 1-2 wires

with a diameter 16 mm Then the insulation is secured

to the duct by welded pins

A inovative solution is the considerable simplification of

a fire-stopping concept There is no need to use any kind

of stiffener either inside or outside of the duct A great

advantage is to mount the whole ventilation section

at once and the wall itself can be placed anywhere

Therefore the position variability of fire separation is

provided No glue or mastic is needed at wallfloor

penetrations

Fire classification

ORSTECH Protect insulation with fire resistance has

been tested by the fire testing laboratory Pavus as an

authorised body AO 216 Classification protocols on the

request

Fire protection system ORSTECH Protect has been tested

in accordance with EN 1366-1 Maximum size for the

rectangular duct is 1250 x 1000 mm and for the circular

duct up to diameter 1000 mm If a duct has bigger

dimensions the certificate connected to the standard

cannot be used

capabilities

for retrofitting purposes

Insulation is usually fixed by mechanical fasteners - by

studs or pins Spacing between them is dependent on the

design of the vessel its surface temperature fire hazard

potential involved and presumptive loading Each slab

should be fixed by minimally two pins

BOILER INSULATIONInsulations for boilers kettles and ovens are one of

the most demanding applications in industry because

these units are operating at very high temperatures

Good insulation not only saves energy considerably but

the main purpose is personal protection against burn

According to the surface shape and temperature are used

either slabs with higher densities Orstech 65 to 110 (for

boilers with flat surfaces) or wired mats Orstech DP 65 to

DP 100 (for boilers with cylindrical parts)

Boiler walls are exposed to very high temperatures

(usually around 500 or 600 degC) Therefore it is essential

to use mechanical fasteners for the fixing of insulation

to the surface Insulation for boilers is done in at least

two layers each layer must be staggered when applied

Each layer must be secured in place before the next is

applied A product with high density should be placed as

the first layer because it has a higher maximum surface

temperature (higher resistance against high operating

temperatures) and better insulation performace than

products with lower densities

CHIMNEY INSULATION

Insulations for prefabricated chimneys are directly

supplied by producers of such systems In cooperation

with specialized wholesale companies we offer slabs

with multi-plate stripes which allow easy and perfect

application for prefabricated chimneys suitable both

for stainless steel chimney liners as well as with other

brands of chimney lining systems The main advantage

is the time saving during the installation in comparison

with the use of lamella mats and horizontal orientation

of fibres (better thermal conductivity) Insulation

dimensions ie thickness of slabs and groove dimensions

dependent on the chimney diameter are supplied

according to customer needs

For non-prefabricated chimneys are mostly used wired

mats Orstech DP or slabs Orstech 90 or 110 (for chimneys

with rectangular cross-section)

TECHNOLOGICAL APPLIANCEINSULATIONWhere big quantities of energy is used eg within

petrochemical paper and pulp industries thermal

insulation is necessary in order to reduce expensive

energy losses Tanks vessels exhausts exchangers

and technological piping are appliances that are often

working at high temperatures Good insulation will save

energy considerably which will benefit the environment

and keep the working costs down At the same time

the insulation will reduce temperature fall which could

disturb the production process

Proper insulation can be chosen in accordance with

dimension surface temperature the manner of fixing

and requirements for jacketing For pipes and cylindrical

parts are used lamella mats Orstech LSP H and Isover

ML-3 (only for temperatures up to 250 degC) or wired mats

Orstech DP For appliances and vessels with rectangular

shapes Orstech slabs are suitable (type according to a

surface temperature) Slabs can have aluminium facing

If insulation is done in more than one layer each layer

is staggered when applied Each layer must be secured

in place before the next is applied The decision to use

multiple layers may be made for one or more of the

following reasons

performance at high temperature surfaces) Mineral woolinsulations have a melting point higher than 1000 degC

For outdoor application metal steel jacketing is

required If a product is with an aluminium facing then

the surface temperature must not exceed 100 degC on the

facing proper thickness of insulation must be designed

for this purpose Binders and greasing agents in mineral

wool products dissolve and evaporate in areas with

temperatures higher than 150 degC As the temperaturefalls in the direction of the insulationrsquos cold side the

binder remains unchanged in the greater part of the

material In the outer areas colder than 150 degC no

dissolution and evaporation take place

AS QUALITY

Corrosion of stainless steel surfaces under insulation

is an often discussed issue Highly alloyed austenitic

steel (alloyed by chrome nickel and molybdenum) are

predisposed to tensile stress corrosion (stress corrosion

cracking) which is caused by chloride ions Austenitic

is a description of crystalline steel structure therefore

identified as AS Chlorides with water (well-known

is classical salt) attack steel surface and cause cracks

in the material With increasing surface temperature

the danger of stress corrosion cracking is raised To

minimise this danger mineral wool insulations in AS

quality are available for this application Standard AGI

Q 132 determines maximum content of chloride ions of

10 mg in 1 kg of the insulation material Mineral woolinsulations may be used for insulating objects made

of stainless austenitic steels if the content meets the

requirement Isover stone wool technical insulations

meet the requirement of AGI Q 132

THERMAL CONDUCTIVITY

One of the most important parameters of insulations is

their thermal conductivity named lambda value λ [W

(mK)] Thermal conductivity measures the capacity of a

material to lead or to resist heat transfer The smaller

the lambda value the better the thermal insulation

The thermal performance of mineral wool is achievedthrough the entrapment of air within the material Its

thermal conductivity does not deteriorate over time

For slabs mats felts and loose mineral wool the

thermal conductivity is determined in the hot box

tester according to EN 12 667 The determination of the

thermal conductivity of sections is in the pipe tester

according to EN ISO 8497 For lamella mats and wired

mats the thermal conductivity is measured in the hot

box and in the pipe tester The thermal conductivity of

mineral wool insulations has to be determined up to the

maximum service temperature (hot face) as a function

of the mean temperature (arithmetic mean betweenobject and surface temperature)

The thermal conductivity varies with temperatures and

with densities The higher the density the higher the

thermal performance at high temperature surfaces In

our product data sheets declared lambda-values λD

are

used these values are fulfilled within every product

A designer will be on the safe side when using our

declared lambda-values That means allowances for

workmanship spacers and supporting constructions

are made Possible inaccuracies caused by calculation

equations can be eliminated

MELTING POINT OF MINERAL WOOL

PRODUCTS

The melting point of mineral wool is determined

according to DIN 4102 part 17 It is a parameter for

the durability of mineral wool insulations in building

components in case of fire It must not be confused

with the maximum service temperature and has no

relation to the service temperature Mineral wool

insulations have the melting point higher than 1000 degC

usually in the range from 1200 to 1600 degC

MAXIMUM SERVICE TEMPERATURE

Maximum service temperature according to EN 14 706

(for wired mats lamella mats and slabs) and EN 14 707

(for pipe sections) ranging from 250 to 700 degC MST for

various products can be found in a Product data sheet

or at the end of the catalogue in the chapter Isover

Products on page 23

FIRE RESISTANCE

Mineral wool products Isover are completely non-

combustible they resist to high temperatures and thus

prevent fire spread The classification levels according

to EN 13 501-1 are A1 possibly A2 for materials with

a facing

ACOUSTIC PROPERTIESIsover mineral wool products have a fibre structure

and therefore reach excellent noise attenuation for

example from HVAC services (pipework ductwork

and air handling equipment) and other services An

absorbent layer of mineral wool has the best absorption

capacity in the medium and high frequencies (under

such conditions it can have absorption coefficient up to

98 (α = 095)) The absorption in the low frequencies

is improved by increasing the thickness or by providing

an air gap behind the absorbent layer

RESISTANT TO BIOLOGICAL PESTSMineral wool insulation is resistent to wood-destroying

pests rodents and insects They are rot-proof and do

not sustain growth of mould

LOW THERMAL EXPANSION

Mineral wool insulations have almost zero thermal

expansion with changing temperatures

MOISTURE AND WATER REPELLENCE

All Isover products are treated during manufacture with

special additives which make them water repellent

Isover products are a hydrophobic non-hygroscopicinsulation material If Isover products get wet they

dry out quickly as a result of the open structure and its

mechanical and insulating properties are unaffected

after drying For outdoor application metal steel

jacketing is unconditional ly required

BASIC FUNCTIONS OF TECHNICAL INSULATIONS

Insulations are defined as those materials which retard

the flow of heat energy by performing one or more of

the following functions

Energy conservation minimizing unwanted heat loss

gain from building HVAC systems as well as preserv-

ing natural and financial resources

Personnel protection controlling surface tempera-tures to avoid contact burns (hot or cold) ndash maximum

surface temperature criterion

Condensation control minimizing condensation by

keeping the surface temperature above the dew point

of surrounding air

Prevent internal condensation in pipes

Process control minimizing temperature change in

process fluids where close control is needed

Increase operating efficiency of heating ventilating

cooling plumbing steam process and power systems

found in commercial and industrial installations

Freeze protection minimizing energy required for

heat tracing systems andor extending the time to

freeze in the event of system failure Freeze protec-

tion of vessels and tanks with various accumulated

fluids or fuels

Noise control reducingcontrolling noise in mechani-

cal systems

Fire safety protecting critical building elements and

slowing the spread of fire in buildings

The application of thermal insulation on pipe vessels

and ducts is recognized as a necessary requirement in

any construction activity The thickness and extent of

insulation required has always been subject to arbi-

trary and imprecise decisions with little engineering or

economic input No material incorporated in a modern

construction project provides the owner with as good

a financial return throughout the life of the facility as

does insulation

The investment in insulation may protect the equip-

ment and personnel present during the life of the facil-

ity Proper insulation prevents condensation chemical

corrosion and excessive heat in fire hazard areas Added

human comfort provided by proper insulation in hotelsoffice buildings schools or factories adds considerably

to the value of the facility and productivity of its per-

sonnel Process temperatures in heat traced piping are

more efficiently maintained with proper insulation The

size of the heat generating equipment can be reduced

when designed with an efficient insulation system In

some cases insulation is essential to an industrylsquos very

existence as with the power the process and

the cold storage

However the most substantial return on an investment

in insulation is in energy savings over a period of timeThese savings are becoming more and more empha-

sized in the industrial insulation field as energy costs

rise coupled with the fact that industrial plants and

utilities usually account for about half of the total en-

ergy consumption

Recently the environmental impact of new renovated

or relocated industrial and commercial facilities has

taken on new importance Thermal insulation is one of

the most if not the most significant technology used

to conserve energy thereby reducing pollution Besides

minimizing heat loss insulation increases process ef-

ficiency helps maintain employee safety comfort and

production

For their thermal protection of various industrial appli-

cations it is a necessity to design and use such insula-

tion material that meet operating conditions Isover will

help you find the most suitable insulation product for

given application

HEAT FLOW TRANSMISSION

Heat transfer is carried out by three heat transmission

modes conduction convection and radiation

Conduction

Heat transfers from warmer surface to colder through

solid material or gas (by fibres in mineral wool

insulations) The more insulant the material the less

the conduction

Convection

Transfer of heat caused by air movements (because of

temperature and density gradient) Hot air moves up

and heat dissipates The quieter the air the less the

convection Convection can be natural (when calculating

insulation inside the building) or forced (for calculation

outside where wind blows)

Radiation

Each material absorbs or emits thermal radiations

depending on its temperature and its emissivity Unlike

conduction or convection heat can be transferred by

radiation also in a vacuum When radiation is absorbed

or reflected there is less thermal transfer Measure of

radiating capacity of a material is emissivity ε Absolute

black body has the highest emissivity (ε = 1) Rough

and dark surfaces approaches such value (for example

mineral wool insulation without jacketing ε = 094)

contrary to bright and smooth surfaces that have very

low emissivity (for example polished aluminium foil ε

= 005) For design it is necessary to take into account

that covering of the bright surface with dust will

increase emissivity significantly

These three transport mechanisms are applied in

two very important quantities ndash surface heat transfer

coefficient α and thermal transmittance U

Thermal insulations impede conduction convection and

radiative effects

by creating a thermal barrier against conductionby suppressing air movements

by limiting radiative effects

Surface heat transfer coefficient

Two heat transmissions (convection and radiation)

influence the heat transfer coefficient α [W(m2middotK)] The

higher the heat transfer coefficient the higher the heat

flow rate from a warm surface

Thermal transmittance

Thermal transmittance (also called Overall heat transfer

coefficient) U (for flat surfaces [W(m2middotK)] for pipes [W

(mmiddotK)]) is inverted value of thermal resistance and it

takes into account the influence of all heat transmission

modes (conduction convection and radiation)

INSULATION SYSTEM DESIGN

GENERAL

An insulation system is the combination of insulations

finishes and application methods which are used toachieve specific design objectives Among these are

Energy savings

Reduced operating costs

Condensation control

Chemical compatibility with the metals being

insulated the atmosphere to which the system

will be exposed and the various components of the

insulation system itself

Protection of mechanical and insulation systems

from mechanical abuse and atmospheric damage

Personnel protection

Fire protection

Sound control

Future requirements for access to piping fittings etc

Accommodation to limited clearances or work space

While there are several choices of insulation materials

which meet basic thermal and cost-effective

requirements of an installation choices become more

limited with each additional design objective that

comes into play

INSULATION THICKNESS CALCULATION

When calculating the thickness of the insulation it isessential to put in appropriate boundary conditions lt

should be noted that the steady-state calculations are

dependent on boundary conditions Often a solution

at one set of boundary conditions is not sufficient to

characterize a thermal system which will operate in a

changing thermal environment (process equipment

operating year-round outdoors for example) In such

cases local weather data based on yearly averages or

yearly extremes of the weather variables should be

used for the calculations

The heat flow through a surface at any point is a function

of several variables which are not directly related

to insulation quality Among others these variables

include ambient temperature movement of the air

roughness and emissivity of the heat flow surface and

the radiation exchange with the surroundings (often

including a great variety of interest) For the calculation

of dew formation variability of the local humidity is animportant factor

Insulation desigh criterion

Apart from a choice of suitable insulation material

for given application it is essential to design proper

insulation thickness It can be determined from two

points of view

Heat loss minimalisation it means reaching the highest

possible economic savings (ideally to calcutate economic

insulation by so- called optimalisation)

Maximum surface temperature (personal protection

against burn) It is usually prescribed by nationallegislation Usual maximum surface temperature is

50 degC if the surrounding air temperature is 25 degC If the

air temperature is different temperature difference

between surface and surrounding air should be up to

25 degC Outdoor piping shall be controlled for maximum

surface temperature every time for summer period

(in the Central Europe calculation air temperature is

30 degC) In boiler rooms surrounding air temperature is

minimally 35 degC

Parameters influencing insulation thick-

ness designHeat flow from the insulation surface is a function of

several parameters which do not relate directly to the

quality of the insulation Here are several parameters

that influence design

thermal conductivity of the insulation material

medium temperature

ambient temperature

external heat transfer coefficient

ECONOMIC THICKNESS

The most substantial return on an investment ininsulation is in energy savings over a period of time

Thermal insulation is one of the most if not the most

significant technology used to conserve energy thereby

reducing pollution Rising energy costs guarantee an

increasing return on any investment made in insulation

In fact it costs less to insulate than not to In the case

of steam process and heat the difference in capital

investment necessary to provide equipment for the

extra steam capacity needed on underinsulated systems

and that investment necessary to insulate plus the

cost of insulation still represents a significant capital

investment savings That insulation saves money is not

the issue here The issue is how much

8122019 Catalogue of Technical Insulations 2013-10-598 En

httpslidepdfcomreaderfullcatalogue-of-technical-insulations-2013-10-598-en 828

Economic thickness calculations are based on the law

of diminishing returns Because no insulation material

can completely stop the flow of heat each increment ofinsulation added to the thickness saves only a percentage

of the heat which has escaped through the underlying

insulation Therefore each increment of insulation

saves less than the one before it and must be evaluated

against the cost of installation to determine if it is a

ldquogood investmentrdquo It is possible to determine how much

insulation applied to a given system will repay its initial

costs in a specified time This point is reached when the

cost of the last incremental of insulation added is offset

by the savings generated by that increment

Refer to the stetch on the left The vertical scale is the

annual cost The horizontal scale is insulation thickness

As the insulation thickness increases from 0 the cost of

heat loss through the insulation decreases Note that this

cost (line B) tends to approach a horizontal line at high

thicknesses As the insulation thickness increases the

cost of the insulation also increases (line A) The total

annual cost at any insulation thickness is the sum of the

cost of the insulation and the cost of the lost heat (line

C) Line C goes through a minimum value of total annual

cost at the Economic thickness

With thicknesses less than the economic thickness the

total annual cost is higher because of the higher valueof the cost of lost heat With thicknesses higher than

the economic thickness the total annual cost is higher

because of the higher value of the cost of the insulation

In the case of computer results each pipe size will be

listed with the recommended thickness as well as

the average heat savings (as compared to a pre-listed

thickness or bare surface whichever chosen) and the

present value of the heat saved

In order to use any of the available manuals tables

or computer programs the two cost factors (cost of

lost energy and cost of insulation) must be found Thefollowing data is generally provided by the investor

Cost of lost energy

This factor is derived from the combination of the

rate of energy transfer the cost of energy and the

operational hours per year of the building Computing

the rate of energy transfer requires surface and

ambient temperatures thermal conductivity of the

chosen insulation the maximumminimum thickness of

insulation to be considered surface emissivity and last

but not least consideration of surface orientation (i evertical horizontal) and wind (air) velocity

Cost of insulation

This factor is derived from computing a bdquounit installed

price of insulationldquo with the total cost annualized overthe projectacutes life The unit installed price is a combination

of the cost of materials cost of labor and worker

MAXIMUM SERVICE TEMPERATURE

MST is determined in a laboratory by testing under de-

fined conditions which are dependent upon the form

of delivery and which are laid down in EN 14 706 (for

wired or lamella mats slabs and felts) and EN 14 707(for pipe sections and segments) MST is determined

by establishing the temperature and time related de-

crease in thickness in one-sided heating For the test

the sample shall take a load of 500 Pa The sample is

heated with a transient of at least 5 Kmin The hot-

face temperature must be maintained for 72 hours at

the expected maximum service temperature At the

maximum service temperature no test result must dis-

play a deformation under load of more than 5

In data sheets of different producers (not only mineral

wool) you will often find MST and value which is not

measured accordance to EN 14 706 This temperature

is only assumed When using such temperature there

is a danger of insulation degradation mainly insulation

thickness If mineral wool product has MST 700 or 750 degC

in its data sheet you can be sure that the material will

not withstand such temperature without degradation

of assessed properties Such temperatures shall not

be used Producers should leave field of assumed MST

and test their products to be able to use declared

MST according to EN 14 706 It is an outstandingimprovement compared to the past because individual

products on the European market can be compared to

each other according to standards valid in the EU

Slabs wired and lamella mats Orstech are certificated

according to valid European standards they are

regularly tested in testing laboratory FIW Muumlnchen

according to VDI 2055 and AGI Q 132 Maximum service

temperatures for various products can be found at the

end of the catalogue in the chapter Isover Products on

EVAPORATION OF BINDERS

Binders and greasing agents in mineral wool products

dissolve and evaporate in areas with temperatures

higher than 150 degC Binder evaporation does not have any

influence on thermal properties only the compactness

of a material is decreased If proper underconstruction

is made there is almost no danger of insulation slide

down But if too small insulation thickness or improper

type of insulation is used (mostly insulation with too

low density for too high temperatures) danger of binder

evaporation in the whole thickness is possible with

consequent insulation slide down In this case no well

made underconstruction will help Insulation will not

work any more In the outer colder areas no dissolution

and evaporation take place

FIRE PERFORMANCE

FIRE ndash a chemical reaction involving rapid oxidation or

burning of a fuel occurs only when three elements are

present in the proper conditions and proportions

FUEL ndash Fuel can be any combustible material - solid

liquid or gas Most solids and liquids become a vapour

or gas before they burn

OXYGEN ndash The air we breathe is about 21 oxygen Fire

only needs an atmosphere with at least 16 oxygen

HEAT ndash Heat is the energy necessary to increase the

temperature of the fuel to a point where sufficient

vapours are given off for ignition to occur

Fire development depends mostly on room geometry

and ventilation the fuel type the amount and surface

area of the fuel Fire is often discussed in terms of the

temperature development and can be divided into

different stages incipience (ignition) growth flashover

fully developed fire and decay

How materials behave in the early stages of a fire from

ignition to flashover (the spontaneous ignition of hot

smoke and gasses) needs to be assessed at the design

stage for buildings and also for plants and equipment

Euroclasses a new European harmonised classification

system for materialsrsquo reaction to fire in most Europeancountries replaced the old national standards The

Euroclass fire classification covers not only materials

used in building structures but it is being extended also

to technical insulations to cover building equipment

and industrial installations This will help to compare

the reaction to fire of different thermal insulation

materials

The classification levels are A1A2 (completely non-

combustible) B C D E and F A1A2 corresponds to

the safest situation E would be the most dangerous

situation and F would mean not classified

ISOVER mineral wool insulations are totally non-

combustible and completely fire safe achieving

Euroclass A1 fire rating (A2 for products with facing)when classified in accordance with EN 13501-1 One

of the most important issues studied under reaction to

fire performance is the potential for flashover to occur

which can lead to a fire spreading uncontrollably Isover

stone wool is not susceptible to flashover

This is a guide to common building materials and their

likely Euroclassification

Check with individual product manufactures for spedific

product specifications

REACTION TO FIRE

Smoke and flaming droplet risk(1) In the EU classification system for reaction to fire

a construction product will be classified as Euroclass A1

A2 B C D E or F depending on its tendency to burn

(2) The product testing will provide data represented

by the signs s1 s2 or s3 which indicate the tendency

to release smoke Smoke causes over 60 of deaths in

fire across the EU The measurement of smoke release

has been put into these 3 broad bands that can be

translated as ldquolittle or no smokerdquo s1 - rdquoquite a lot of

smokerdquo s2 - rdquosubstantial smoke releaserdquo s3

(3) Some construction products like these made of

polystyrene can melt and ignite to form Flaming

Droplets Wooden products on the other hand will tend

to char before the char falls away as Flaming Particles

to expose more material

These rdquoflaming dropletsparticlesrdquo will tend to

initiate new fires away from the original point of

ignition and must be considered when the products

are used horizontally in ceiling or roof applications

FIRE PROTECTION DESIGN FOR VENTILATION DUCTS

Produced with the stone wool technology of Isover

fire protection system ORSTECH Protect is mineral

wool that combines all the advantages of conventionalthermal and acoustic insulation with top level of fire

safety Mineral wool insulations have the melting point

higher than 1000 degC From the fire protection point of

view products Isover are one of the safest materials

ORSTECH Protect consists of slab or lamella mat

solutions offering up to one hour fire protection for

both vertical and horizontal applications of rectangular

and circular ductwork systems

Passive protection of ventilation ducts is possible by

two basic means

Installed a fire damper into the duct to the place of

fire separation

Use a fire protection insulation system which is

tested according EN 1366-1 and has a classification

protocol in accordance with EN 13 501-3 This second

case is covered by insulation system ORSTECH

Protect

LEGISLATION

Air duct which shall resist the spread of fire from one

compartment to another is tested according to EN

1366-1 The standard can be applied to vertical and

horizontal ducts with or without branches for fire inside

or outside the duct The test measures the time period

for which ducts of specified dimensions suspended as

they would be in practice satisfy criteria when exposed

to fire from inside or outside (separately)

This standard is used in conjunction with EN 1363-1

which prescribes requirements for the determinationof fire resistance of various components of building

structures which are exposed to standard fire

conditions In this standard there are failure criteria

whereby it is possible to evaluate the ability of a tested

duct to prevent fire spread due to the destruction of

the duct (integrity failure E) heat transfer (insulationfailure I) and prevention of the smoke penetration

(smoke leakage S) Fire protection is expressed by time

in minutes for which failure criteria are fulfilled

Designation itself is then done according to

classification standard EN 13 501-3 Classification

states if criteria are fulfilled for fire outside (marking

o rarr i) valid for duct type A or fire inside (marking

irarr o) or from both directions (iharr o) valid for duct type

B and if this is valid for a horizontal duct (marking ho)

or a vertical one (ve) or both (ve ho) Eg class bdquoEI 30 S

ndash ve ho (orarr i) Sldquo represents duct capability to maintain

integrity insulation and smoke leakage for time period

of 30 minutes under fire exposure from outside both

for vertical and horizontal positions

MAXIMUM DUCT SIZES

Maximum size is according to EN 1366-1 for rectangular

duct 1250 x 1000 mm and for circular duct up to

diameter 1000 mm If a duct has bigger dimensions the

classification protocol cannot be used

ACOUSTIC PERFORMANCE

Noise is a sound which impacts negatively on the

surroundings Noise levels emanating from HVAC

services (pipework ductwork and air handlingequipment) and other services can be significantly

reduced with the use of Isover products which will

help to achieve acceptable environmental noise levels

Isover insulations are due to its fibre structure an ideal

material for sound attenuation not only for industrial

application The degree of sound insulation will depend

upon the application the thickness of insulation used

and the nature of any finish used to clad over the

installation In suitable frequencies they can absorb up

to 95 of the sound energy (α = 095)

SOUND ABSORPTIONWhen a sound wave strikes a surface the sound energy

is broken down into transmitted energy (through the

material) converted energy (usually heat) and reflected

energy (back towards the source of the sound)

The more absorbent the material the less sound is

reflected That part of sound energy which is converted

and transmitted is usually expressed as an absorption

coefficient α

The absorption coefficient for a material varies with

the frequency An absorbent layer of mineral wool

has the best absorption capacity in medium and high

frequencies The absorption in low frequencies is

improved by increasing the thickness or by providing an

air gap behind the absorbent layer

Examples of the effectiveness of Isover products in noise

control are given in the following table

ABSORPTIVE STRUCTURES

The most common task in room acoustics is to attenuate

or cancel some frequencies or a whole frequency band

This is possible to realise by using convenient absorptive

material or structures which are frequency-dependent

In this way we can control not only absorption ie

reverberation time but also suppress or completely

remove unpleasant sounds

In a porous material acoustic absorption is mainlycaused by friction in pores ie friction between

oscillating particles and the surface of pores Since the

energy loss due to friction is proportional to the length

of the path the most absorption will occur when the

porous material is placed in a position where the particle

displacement is the largest (maxima displacement)

When sound strikes a rigid wall like concrete for

example a standing wave result and the maxima of

particle displacement appear at the distances λ14

3λ24 5λ

34 hellip from the surface of a room These are the

critical distances which must be covered by adsorbers

ie layers with thicknesses d1 = λ

14 d

2 = 3λ

24 d

3 = 5λ

34

In short an absorber with a thickeness d placed directly

on the solid structure will effectively attenuate only

those frequencies where f ge c4d (c is the velocity of

sound 340 ms) For example insulation thickness

of 50 mm wil l reliably attenuate frequencies higher

than 1700 Hz thickness 100 mm then already from

frequencies 850 Hz The higher the frequency the

shorter the wave length and better attenuation

An absorbing layer tightly adjacent to a solid structure

has nevertheless one disadvantage To attenuate

low frequencies it would be necessary to use verythick layers (for example for attenuation of 500 Hz a

thickness of about 20 cm would be necessary) Therefore

acoustic tiles can hardly attenuate low frequency noise

(frequencies lower than 100 dB such as noise from

discotheques)

Fortunately it is possible to avoid expensive acoustic

tiles with high thickness If we use a very thin layer

and place it just in the position of the displacement

maximum of a chosen frequency this chosen frequency

and its odd multiples will be attenuated Acoustic

tiles thus work as a selective frequency filter On theselective basis also other acoustic attenuators work

namely membranes oscillating plates and resonators

ACOUSTICS INSULATIONS

Isover stone wool products with a high longitudinal air-

flow resistance (up to 95 kPasm2) and uniform porosity

(93 ndash 99 ) are used as sound attenuation insulations

In suitable frequencies they can absorb up to 95 of

the sound energy (α = 095) Sound attenuation in a

construction is related to elastic properties of Isover

mineral wool insulations and their low modulus of

elasticity (they have low dynamic toughness and

therefore they are much more suitable for acoustic

purposes in comparison with foam plastics)

Sound attenuation properties of Isover products are

characterised by an absorption coefficient α which

can be found in the table for three thicknesses andsix frequencies According to a given noise spectrum

it is possible to design a sound attenuation structure

of which our material is only a part Since we provide

only insulation material we launch only absorption

coefficients Final attenuation will be dependent on

the whole designed construction (considering also

supporting construction hangers) and assembly

Isover does not design sound attenuation and thus it

is necessary to ask specialists who are able to design a

proper structure

Generally we can say that transmission loss is higher

for constructions with higher plane weight therefore

in most cases insulation with higher density has

better sound attenuation (eg slabs Orstech 65 90

110 Isover FireProtect 150) than insulation with lower

density (eg Orstech 45) Slabs can be manufacturedwith a facing ndash glass black tissue

GENERAL RULES FOR USING ISOVER INSULATIONS

Between insulated piping sufficient distances must

be kept

Valves should be placed without needing to go on theinsulated pipes when handling them

Spindle of valves should not be installed in an upward

direction to avoid water leakage into the insulation

Surfaces before insulating must be clean and dry It

is not possible to insulate wet or frostbitten surfaces

which may later cause damages of insulation or

insulated surfaces

Dirt and rust must be rubbed down from untreated

carbon steels

Smear and oils must be removed by detergents or

solvents from insulated surfaces

Stainless steel surfaces must not be cleaned by

detergents or solvents with chloride content They

may be cleaned only by stainless steel brushes

Chloride solution attacks stainless steel surface and

causes stress corrosion cracking in the material With

increasing surface temperature the danger of stress

corrosion cracking is raised

Piping and equipment from stainless steel can be

insulated only by mineral wool insulation in AS

quality Such material can have maximum content

of chloride ions of 10 mg in 1 kg of the insulation

material

It is necessary to avoid contact of metals which can

cause galvanic corrosion (Cu-Zn Fe-Al)For operating temperatures higher than 600 degC

aluminium jacketing should not be used

Self-tapping screw bold or rivet should be from the

same material as the jacketing

Surfaces with temperatures higher than 500 degC

should be insulated by more insulation layers in a

way that each layer has a different apparent density

Material with higher density insulates better under

higher temperatures than material with lower

density therefore insulation with higher density is

placed closer to the hot side Under low operating

temperatures thermal performance is almost equalSafety working principles must be kept for insulation

assembly

Isover products are packed into PE foil They must be

transported in covered vehicles under such conditions

to avoid moistening or other degradation They must

be stored in covered places

httpslidepdfcomreaderfullcatalogue-of-technical-insulations-2013-10-598-en 1528

Wired mats

After the cutting of needed length the wired mat shall

be tightly wrapped on the pipe Wired matsrsquo butt jointsshould be in close contact to each other to ensure no

gaps between mats For multiple layer construction

each layer is staggered when applied Each layer must

be secured in place before the next is applied Individual

mats are bound together with a wire with minimal 07

mm thickness Alternatively wired hook or stainless

steel bands (with minimum width of 10 mm) can be

used Maximum distance between hooks is 150 mm

The decision to use multiple layers may be made for one

or more of the following reasons

to provide compensation for pipe expansion andcontraction

to reduce heat flow by staggering joints thus creating

a more thermally efficient installation

to achieve thickness in excess of manufacturersrsquo

capabilities

for retrofitting purposes

Lamella mats

Lamella mats Orstech LSP H consist of mineral wool

lamellas which have been glued to aluminium foil

reinforced with a glass fibre grid and these fibres are

predominantly perpendicular to the surface of themat Compressive strength but thermal conductivity

too are increased compared to mats with a fibre

orientation parallel to the surface (wired mats) Due

to its compressive strength resistance they have less

demands for undeconstruction (less thermal bridges)

in comparison with wired mats Temporary securing in

place is done by aluminium tapes final fixing shall be

done by a baling wire

Protective coverings

The efficiency and service of insulation is directly

dependent upon its protection from moisture entry andmechanical and chemical damage Choices of jacketing

materials are based upon the mechanical chemical

thermal and moisture conditions of the installation

as well as cost and appearance requirements The

basic function of the weather protection is to protect

the insulation from rain snow sleet wind solar

radiation atmospheric contamination and mechanical

damage With this definition in mind several service

requirements must be considered

PIPING INSULATION

For domestic hot water piping with smaller diameters

insulation pipe sections which are covered withaluminium foil are ideal Pipe sections with a facing

have a self-adhesive overlap in a longitudinal joint

to ensure perfect enclosure of a pipe section It is

recommended to secure pipe sections by an aluminium

tape or by galvanized wire transversely They are usually

knotted three times per meter more for pipe sections

with higher diameter Higher diameters should be

secured either by wire or by metal band (at least two

bands per meter)

Pipings with bigger diameters are most commonly

insulated by lamella mats Orstech LSP (stone woolinsulation) or Isover ML-3 (glass wool insulation)

eventually by wired mats Orstech DP (especially for higher

temperatures) Lamella and wired mats are also suitable

for appliances and vessels (both ends and cylindrical

parts) residential heating systems and air ducts

Internal mechanical forces ndash expansion and contraction

of the pipe or vessel must be considered because the

resulting forces are transferred to the external surface ofthe weather barrier Ability to slide elongate or contract

must be provided

External mechanical forces ndash mechanical abuse (ie

tools being dropped abrasion from wind-driven sand

personnel walking on the system) inflicted on a pipe or

vessel needs to be considered in design This may affect

insulation type as well as the weather barrier jacketing

type

Chemical resistance Some industrial environments may

have airborne or spilled corrosive agents that accumulate

on the weather barrier and chemically attack the pipe or

vessel jacketing Elements that create corrosive issues

must be well understood and accounted for Insulation

design of coastal facilities should account for chloride

attack

Galvanic corrosion Contacts between two different

types of metal must be considered for galvanic corrosion

potential Similarly water can act as an electrolyte and

galvanic corrosion can occur because of the differentpotential of the pipe and vessel and a metal jacketing

Materials used as weather barriers for insulation

Typical metal jacketing materials bare aluminium coated

aluminium stainless steel painted steel galvanized steel

aluminium-zinc coated steel

Typical polymeric jacketing materials polyvinyl chloride

(PVC) polyvinyliedene chloride (PVDC) polyisobutylene

multiple-layer composite materials (eg polymericfoil

mesh laminates) fabrics (silicone-impregnated fibreglass)

Fittings valves

Insulation of fittings valves flanges and couplings is

the most time consuming and often expensive aspectof commercial and industrial insulation But it is crucial

to insulate also these parts properly otherwise most of

energy will be transported by these thermal bridges For

example for 200 degC medium heat loss of one uninsulated

valve corresponds to one meter of uninsulated pipe or

ten meters of uninsulated pipe

Fittings are items used to change size direction of flow

level or assembly of piping They may be of the screwed

sweat or welded types Valves are any of various devices

that regulate liquid or gas flow and they may be of the

screwed sweated flanged or welded types Flanges areprotruding rims and edges of the screwed or sweated

type used with fittings valves couplings etc And finally

mechanical couplings are devices used in assembly of

piping Screwed and flanged connections on fittings

valves couplings etc usually require oversized insulation

applications to compensate for the protrusions

Minimum spacing between pipes and

constructions

It is essential to ensure sufficient space between pipies

and between a pipe and a wall (minimally 100 mm)

Otherwise there is a great danger of creating a zone withalmost no cenvenction The result can be too high surface

temperature (needed personal protection against burn)

or possibility of condensation on cold piping Besides

mounting would have been more difficult

DUCTING INSULATION

Isover products are designed to provide high levels of

thermal acoustic and fire protection insulation in HVACductwork applications such as rectangular flat oval and

circular ductwork

The most suitable insulation materials for ducts are

felts KLIMAROL with aluminium foil facing lamella mats

Orstech LSP or Isover ML-3 wired mats Orstech DP or

slabs Orstech H with aluminium foil facing

Duct insulation mounting

Insulation is mostly fixed to the duct by welded pinsWhen using Orstech H slabs with aluminium facing all

the joints shall be sealed with aluminium tape If a steel

clamping band is used it is necessary to use thin-walled

steel L-profiles to avoid trimming of the insulation If

using Orstech slabs without aluminium facing or Orstech

DP wired mats proper jacketing shall be made (the most

suitable is metal steel jacketing)

It is vital to develop safe durable and reliable solutions

for ventilation systems as fire can easily spread from the

point of origin via ductwork Isover meets the highest

standards for fire protection providing excellent fire

resistance and top-rated reaction to fire performance

Rectangular ducts shall be insulated by Orstech 65 H

slabs with 40 mm thickness (60 mm for fire resistance EI

60 for a horizontal duct) circular ducts shall be insulated

by Orstech LSP PYRO lamella mats with 50 mm thickness

By these solutions fire resistances EI 15 30 45 and 60 S

have been certified to comply with EN 1366-1

Orstech system with fire resistance has been proven to

meet the requirements of all possible scenarios for fire

from the outside The scenarios can be identified by duct

orientation and duct shape (see table below) Horizontal

ducts normally serve one floor of a building Vertical

ducts normally serve between floors of a building All

scenarios have been done only with one layer Insulation

is fixed to a duct by welded pins Such solution is time

and material saving

Metal ductworkThe steel duct is constructed in sections of galvanised

steel sheet or stainless steel sheet minimum 08 mm thick

(standard duct sheeting for rectangular ducts specified

in DIN 24190 for circular ducts in DIN 24145) Maximum

duct size for which classification protocol is valid is 1250

mm (width) x 1000 mm (height) for rectangular duct or

diameter up to 1000 mm for a circular duct

At each cross joint flanges are fastened to the duct

with spot welds at 150 mm nominal centres

Use a ceramic tape gasket and fire-stopping mastic

between the flanges to seal the joints

Flanges are bolted together with an M10 steel nut

and bolt at each corner

Fasten the flanges together with steel clamps with

bolts M8 (see the figure) in quantity of 3 clamps per 1

meter of the flange length

Drop rods and hangers

Rectangular ducts are suspended by threaded rods and

channel section bearers A duct shall be hung with asuspension system which is independently fire rated

according to EN 1363-1 Certificated suspension system

MUPRO is recommended for the purpose Each steel

hanger consists of two threaded drop rods minimum

M10 and a channel section bearer 3840 mm Fasten

the bearer to the drop rods using hexagonal nuts and

washers The drop rods can be positioned either inside

the insulation material or outside If drop rods are outside

there is no need to insulate them separately The bearers

are positioned inside the insulation material

Circular ducts are suspended by MUumlPRO steel hangerswhich consist of two threaded drop rods minimum

M10 and a two-part industrial circular band The ends

of each band section are bent outwards Fasten the band

sections together and attach them to the drop rods with

hexagonal nuts and washers Place these hangers inside

the insulation The rods do not need to be protected by

insulation

When fixing them to a concrete construction use all-

steel expanding anchors to fasten the threaded rod

hangers to concrete soffits The anchors should penetrate

the concrete by at least 60 mm When fixing to a steel

supporting construction drill a hole through the steel

member allowing the drop rod to be supported by a steel

nut and washer above If a clamp type fixing is used the

clamp must be steel suitable for the purpose It should

pass around the steel member and be fastened back on

itself Clamps that rely on friction to hold them in place

are not suitable

Insulation

Rectangular ducts are insulated by Orstech 65 H slabs

(with apparent density 65 kgm3 and with one-sidedaluminium foil facing) with 40 mm thickness (60 mm

for fire resistance EI 60 for a horizontal duct) Circular

ducts are insulated by lamella mats Orstech LSP PYRO

with 50 mm thickness Insulation slabs (lamella mats)

need to be cut to fit the duct as tightly as possible the

insulation may need to be cut to fit around flanged duct

joints Install the insulation so that one slab (lamella

mat) is adjacent and tightly fitted against the other No

gaps must be present between butt joints of insulation

Insulation can be easily cut with a standard laggers knife

There is no need for adhesive on joints All the joints shall

be sealed by aluminium tape For rectangular ducts in theposition of flange the slabs are snick first 15 mm of the

thickness to avoid lifting of the slabs Butt joints should

be positioned out of flanges Fire protective insulation for

circular ducts does not require usage of a wire net mesh

on the outer side of insulation

Stud welded pins

The insulation is fixed to the duct using steel pins 27 mm

to 3 mm nominal diameter and spring steel washers

minimum 30 mm diameter The length of pin should

be equal to the insulation thickness The orientational

number of pins is 16 piecesm2 for rectangular ducts and14 piecesm2 for circular ducts

Recommended distance from duct edges and joints is

80 mm 50 mm from flanges

Wallfloor penetration

At wallfloor penetration one must insure the same fire

resistance of ventilation duct as has the fire separation

to avoid the spreading of fire from one compartment to

other via a duct This is possible by two basic principles

or their combinations - install a fire damper at the

penetration point or use insulation with fire resistancewhere the crucial thing is the fire-stopping The fire-

stopping is from the second insulation layer with the

width of 150 mm from both side of fire separation

The same general principle is used for both rectangular

and circular ducts regardless of orientation Place

the duct in the penetration of the construction with

approximately 10 mm gap between insulated duct and

opening Before installing the fire-stopping with the

same insulation thickness as is used for the first layer

pack the space between the duct and partition with

as many pieces of insulation as possible Ensure tight

compression in order to completely fill the opening This

must be done because system ORSTECH Protect does

not require stiffeners inside the duct Then install thesecond insulation layer so that it is adjacent and tightly

fitted against the penetration The insulation must be

cut leaving excess length so that it exerts some pressure

between the penetration and the last fitted piece of

insulation

The second layer is fixed by welded pins with length

equal to double insulation thickness The second layer for

circular ducts (lamella mats) is clamped with 1-2 wires

with a diameter 16 mm Then the insulation is secured

to the duct by welded pins

A inovative solution is the considerable simplification of

a fire-stopping concept There is no need to use any kind

of stiffener either inside or outside of the duct A great

advantage is to mount the whole ventilation section

at once and the wall itself can be placed anywhere

Therefore the position variability of fire separation is

provided No glue or mastic is needed at wallfloor

penetrations

Fire classification

ORSTECH Protect insulation with fire resistance has

been tested by the fire testing laboratory Pavus as an

authorised body AO 216 Classification protocols on the

request

Fire protection system ORSTECH Protect has been tested

in accordance with EN 1366-1 Maximum size for the

rectangular duct is 1250 x 1000 mm and for the circular

duct up to diameter 1000 mm If a duct has bigger

dimensions the certificate connected to the standard

cannot be used

There is no need to use any

kind of stiffener either in-side or outside of the duct

to provide compensation for pipe expansion and

contraction

to reduce heat flow by staggering joints thus creatinga more thermally efficient installation

to achieve thickness in excess of manufacturersrsquo

capabilities

for retrofitting purposes

Insulation is usually fixed by mechanical fasteners - by

studs or pins Spacing between them is dependent on the

design of the vessel its surface temperature fire hazard

potential involved and presumptive loading Each slab

should be fixed by minimally two pins

BOILER INSULATIONInsulations for boilers kettles and ovens are one of

the most demanding applications in industry because

these units are operating at very high temperatures

Good insulation not only saves energy considerably but

the main purpose is personal protection against burn

According to the surface shape and temperature are used

either slabs with higher densities Orstech 65 to 110 (for

boilers with flat surfaces) or wired mats Orstech DP 65 to

DP 100 (for boilers with cylindrical parts)

Boiler walls are exposed to very high temperatures

(usually around 500 or 600 degC) Therefore it is essential

to use mechanical fasteners for the fixing of insulation

to the surface Insulation for boilers is done in at least

two layers each layer must be staggered when applied

Each layer must be secured in place before the next is

applied A product with high density should be placed as

the first layer because it has a higher maximum surface

temperature (higher resistance against high operating

temperatures) and better insulation performace than

products with lower densities

CHIMNEY INSULATION

Insulations for prefabricated chimneys are directly

supplied by producers of such systems In cooperation

with specialized wholesale companies we offer slabs

with multi-plate stripes which allow easy and perfect

application for prefabricated chimneys suitable both

for stainless steel chimney liners as well as with other

brands of chimney lining systems The main advantage

is the time saving during the installation in comparison

with the use of lamella mats and horizontal orientation

of fibres (better thermal conductivity) Insulation

dimensions ie thickness of slabs and groove dimensions

dependent on the chimney diameter are supplied

according to customer needs

For non-prefabricated chimneys are mostly used wired

mats Orstech DP or slabs Orstech 90 or 110 (for chimneys

with rectangular cross-section)

TECHNOLOGICAL APPLIANCEINSULATIONWhere big quantities of energy is used eg within

petrochemical paper and pulp industries thermal

insulation is necessary in order to reduce expensive

energy losses Tanks vessels exhausts exchangers

and technological piping are appliances that are often

working at high temperatures Good insulation will save

energy considerably which will benefit the environment

and keep the working costs down At the same time

the insulation will reduce temperature fall which could

disturb the production process

Proper insulation can be chosen in accordance with

dimension surface temperature the manner of fixing

and requirements for jacketing For pipes and cylindrical

parts are used lamella mats Orstech LSP H and Isover

ML-3 (only for temperatures up to 250 degC) or wired mats

Orstech DP For appliances and vessels with rectangular

shapes Orstech slabs are suitable (type according to a

surface temperature) Slabs can have aluminium facing

If insulation is done in more than one layer each layer

is staggered when applied Each layer must be secured

in place before the next is applied The decision to use

multiple layers may be made for one or more of the

following reasons

Mineral wool insulation Isover is made from the earthrsquos

most abundant materials rock sand and minerals of

various types The production is based on fiberizingof molten raw materials consisting of minerals and

different amounts of artificial resins Mineral wool

insulation materials are delivered as wired mats lamella

mats slabs blocks pipe sections and felts Depending

upon the form of delivery mineral wool insulations can

be quilted on wire mesh faced with foils glass fleece or

glass filament tissue or be equipped with coatings

Final Isover products have the following properties

apparent density from 25 to 150 kgm3 (special fire

protection slabs can have density up to 200 kgm 3)

very good thermal insulation performance (low

thermal conductivity)

very good sound attenuation (high absorption

coefficient)

fire resistance ndash non-combustible material

high temperature resistance (possibility of application

up to a maximum surface temperature)

environmental friendly and hygienic

hydrophobisation ndash Isover insulation materials are

made water repellent

long life span (material is not aging)

resistant to wood-destroying pests rodents and

insect

easy to handle easy to cut with a sharp knife

The Isover product range provides fire safe thermal

and acoustic insulation solutions in many applications

including HVAC original equipment transport and

for tanks and storage vessels The range of high

quality products has been designed to be effective in

both performance and cost while providing ease of

installation Each product is engineered to fulfil specific

performance criteria Maximum surface temperature

(MST) is dependent on the apparent density (the

higher the density the higher MST and better thermal

performance at high temperature surfaces) Mineral woolinsulations have a melting point higher than 1000 degC

For outdoor application metal steel jacketing is

required If a product is with an aluminium facing then

the surface temperature must not exceed 100 degC on the

facing proper thickness of insulation must be designed

for this purpose Binders and greasing agents in mineral

wool products dissolve and evaporate in areas with

temperatures higher than 150 degC As the temperaturefalls in the direction of the insulationrsquos cold side the

binder remains unchanged in the greater part of the

material In the outer areas colder than 150 degC no

dissolution and evaporation take place

AS QUALITY

Corrosion of stainless steel surfaces under insulation

is an often discussed issue Highly alloyed austenitic

steel (alloyed by chrome nickel and molybdenum) are

predisposed to tensile stress corrosion (stress corrosion

cracking) which is caused by chloride ions Austenitic

is a description of crystalline steel structure therefore

identified as AS Chlorides with water (well-known

is classical salt) attack steel surface and cause cracks

in the material With increasing surface temperature

the danger of stress corrosion cracking is raised To

minimise this danger mineral wool insulations in AS

quality are available for this application Standard AGI

Q 132 determines maximum content of chloride ions of

10 mg in 1 kg of the insulation material Mineral woolinsulations may be used for insulating objects made

of stainless austenitic steels if the content meets the

requirement Isover stone wool technical insulations

meet the requirement of AGI Q 132

THERMAL CONDUCTIVITY

One of the most important parameters of insulations is

their thermal conductivity named lambda value λ [W

(mK)] Thermal conductivity measures the capacity of a

material to lead or to resist heat transfer The smaller

the lambda value the better the thermal insulation

The thermal performance of mineral wool is achievedthrough the entrapment of air within the material Its

thermal conductivity does not deteriorate over time

For slabs mats felts and loose mineral wool the

thermal conductivity is determined in the hot box

tester according to EN 12 667 The determination of the

thermal conductivity of sections is in the pipe tester

according to EN ISO 8497 For lamella mats and wired

mats the thermal conductivity is measured in the hot

box and in the pipe tester The thermal conductivity of

mineral wool insulations has to be determined up to the

maximum service temperature (hot face) as a function

of the mean temperature (arithmetic mean betweenobject and surface temperature)

The thermal conductivity varies with temperatures and

with densities The higher the density the higher the

thermal performance at high temperature surfaces In

our product data sheets declared lambda-values λD

are

used these values are fulfilled within every product

A designer will be on the safe side when using our

declared lambda-values That means allowances for

workmanship spacers and supporting constructions

are made Possible inaccuracies caused by calculation

equations can be eliminated

MELTING POINT OF MINERAL WOOL

PRODUCTS

The melting point of mineral wool is determined

according to DIN 4102 part 17 It is a parameter for

the durability of mineral wool insulations in building

components in case of fire It must not be confused

with the maximum service temperature and has no

relation to the service temperature Mineral wool

insulations have the melting point higher than 1000 degC

usually in the range from 1200 to 1600 degC

MAXIMUM SERVICE TEMPERATURE

Maximum service temperature according to EN 14 706

(for wired mats lamella mats and slabs) and EN 14 707

(for pipe sections) ranging from 250 to 700 degC MST for

various products can be found in a Product data sheet

or at the end of the catalogue in the chapter Isover

Products on page 23

FIRE RESISTANCE

Mineral wool products Isover are completely non-

combustible they resist to high temperatures and thus

prevent fire spread The classification levels according

to EN 13 501-1 are A1 possibly A2 for materials with

a facing

ACOUSTIC PROPERTIESIsover mineral wool products have a fibre structure

and therefore reach excellent noise attenuation for

example from HVAC services (pipework ductwork

and air handling equipment) and other services An

absorbent layer of mineral wool has the best absorption

capacity in the medium and high frequencies (under

such conditions it can have absorption coefficient up to

98 (α = 095)) The absorption in the low frequencies

is improved by increasing the thickness or by providing

an air gap behind the absorbent layer

RESISTANT TO BIOLOGICAL PESTSMineral wool insulation is resistent to wood-destroying

pests rodents and insects They are rot-proof and do

not sustain growth of mould

LOW THERMAL EXPANSION

Mineral wool insulations have almost zero thermal

expansion with changing temperatures

MOISTURE AND WATER REPELLENCE

All Isover products are treated during manufacture with

special additives which make them water repellent

Isover products are a hydrophobic non-hygroscopicinsulation material If Isover products get wet they

dry out quickly as a result of the open structure and its

mechanical and insulating properties are unaffected

after drying For outdoor application metal steel

jacketing is unconditional ly required

BASIC FUNCTIONS OF TECHNICAL INSULATIONS

Insulations are defined as those materials which retard

the flow of heat energy by performing one or more of

the following functions

Energy conservation minimizing unwanted heat loss

gain from building HVAC systems as well as preserv-

ing natural and financial resources

Personnel protection controlling surface tempera-tures to avoid contact burns (hot or cold) ndash maximum

surface temperature criterion

Condensation control minimizing condensation by

keeping the surface temperature above the dew point

of surrounding air

Prevent internal condensation in pipes

Process control minimizing temperature change in

process fluids where close control is needed

Increase operating efficiency of heating ventilating

cooling plumbing steam process and power systems

found in commercial and industrial installations

Freeze protection minimizing energy required for

heat tracing systems andor extending the time to

freeze in the event of system failure Freeze protec-

tion of vessels and tanks with various accumulated

fluids or fuels

Noise control reducingcontrolling noise in mechani-

cal systems

Fire safety protecting critical building elements and

slowing the spread of fire in buildings

The application of thermal insulation on pipe vessels

and ducts is recognized as a necessary requirement in

any construction activity The thickness and extent of

insulation required has always been subject to arbi-

trary and imprecise decisions with little engineering or

economic input No material incorporated in a modern

construction project provides the owner with as good

a financial return throughout the life of the facility as

does insulation

The investment in insulation may protect the equip-

ment and personnel present during the life of the facil-

ity Proper insulation prevents condensation chemical

corrosion and excessive heat in fire hazard areas Added

human comfort provided by proper insulation in hotelsoffice buildings schools or factories adds considerably

to the value of the facility and productivity of its per-

sonnel Process temperatures in heat traced piping are

more efficiently maintained with proper insulation The

size of the heat generating equipment can be reduced

when designed with an efficient insulation system In

some cases insulation is essential to an industrylsquos very

existence as with the power the process and

the cold storage

However the most substantial return on an investment

in insulation is in energy savings over a period of timeThese savings are becoming more and more empha-

sized in the industrial insulation field as energy costs

rise coupled with the fact that industrial plants and

utilities usually account for about half of the total en-

ergy consumption

Recently the environmental impact of new renovated

or relocated industrial and commercial facilities has

taken on new importance Thermal insulation is one of

the most if not the most significant technology used

to conserve energy thereby reducing pollution Besides

minimizing heat loss insulation increases process ef-

ficiency helps maintain employee safety comfort and

production

For their thermal protection of various industrial appli-

cations it is a necessity to design and use such insula-

tion material that meet operating conditions Isover will

help you find the most suitable insulation product for

given application

HEAT FLOW TRANSMISSION

Heat transfer is carried out by three heat transmission

modes conduction convection and radiation

Conduction

Heat transfers from warmer surface to colder through

solid material or gas (by fibres in mineral wool

insulations) The more insulant the material the less

the conduction

Convection

Transfer of heat caused by air movements (because of

temperature and density gradient) Hot air moves up

and heat dissipates The quieter the air the less the

convection Convection can be natural (when calculating

insulation inside the building) or forced (for calculation

outside where wind blows)

Radiation

Each material absorbs or emits thermal radiations

depending on its temperature and its emissivity Unlike

conduction or convection heat can be transferred by

radiation also in a vacuum When radiation is absorbed

or reflected there is less thermal transfer Measure of

radiating capacity of a material is emissivity ε Absolute

black body has the highest emissivity (ε = 1) Rough

and dark surfaces approaches such value (for example

mineral wool insulation without jacketing ε = 094)

contrary to bright and smooth surfaces that have very

low emissivity (for example polished aluminium foil ε

= 005) For design it is necessary to take into account

that covering of the bright surface with dust will

increase emissivity significantly

These three transport mechanisms are applied in

two very important quantities ndash surface heat transfer

coefficient α and thermal transmittance U

Thermal insulations impede conduction convection and

radiative effects

by creating a thermal barrier against conductionby suppressing air movements

by limiting radiative effects

Surface heat transfer coefficient

Two heat transmissions (convection and radiation)

influence the heat transfer coefficient α [W(m2middotK)] The

higher the heat transfer coefficient the higher the heat

flow rate from a warm surface

Thermal transmittance

Thermal transmittance (also called Overall heat transfer

coefficient) U (for flat surfaces [W(m2middotK)] for pipes [W

(mmiddotK)]) is inverted value of thermal resistance and it

takes into account the influence of all heat transmission

modes (conduction convection and radiation)

INSULATION SYSTEM DESIGN

GENERAL

An insulation system is the combination of insulations

finishes and application methods which are used toachieve specific design objectives Among these are

Energy savings

Reduced operating costs

Condensation control

Chemical compatibility with the metals being

insulated the atmosphere to which the system

will be exposed and the various components of the

insulation system itself

Protection of mechanical and insulation systems

from mechanical abuse and atmospheric damage

Personnel protection

Fire protection

Sound control

Future requirements for access to piping fittings etc

Accommodation to limited clearances or work space

While there are several choices of insulation materials

which meet basic thermal and cost-effective

requirements of an installation choices become more

limited with each additional design objective that

comes into play

INSULATION THICKNESS CALCULATION

When calculating the thickness of the insulation it isessential to put in appropriate boundary conditions lt

should be noted that the steady-state calculations are

dependent on boundary conditions Often a solution

at one set of boundary conditions is not sufficient to

characterize a thermal system which will operate in a

changing thermal environment (process equipment

operating year-round outdoors for example) In such

cases local weather data based on yearly averages or

yearly extremes of the weather variables should be

used for the calculations

The heat flow through a surface at any point is a function

of several variables which are not directly related

to insulation quality Among others these variables

include ambient temperature movement of the air

roughness and emissivity of the heat flow surface and

the radiation exchange with the surroundings (often

including a great variety of interest) For the calculation

of dew formation variability of the local humidity is animportant factor

Insulation desigh criterion

Apart from a choice of suitable insulation material

for given application it is essential to design proper

insulation thickness It can be determined from two

points of view

Heat loss minimalisation it means reaching the highest

possible economic savings (ideally to calcutate economic

insulation by so- called optimalisation)

Maximum surface temperature (personal protection

against burn) It is usually prescribed by nationallegislation Usual maximum surface temperature is

50 degC if the surrounding air temperature is 25 degC If the

air temperature is different temperature difference

between surface and surrounding air should be up to

25 degC Outdoor piping shall be controlled for maximum

surface temperature every time for summer period

(in the Central Europe calculation air temperature is

30 degC) In boiler rooms surrounding air temperature is

minimally 35 degC

Parameters influencing insulation thick-

ness designHeat flow from the insulation surface is a function of

several parameters which do not relate directly to the

quality of the insulation Here are several parameters

that influence design

thermal conductivity of the insulation material

medium temperature

ambient temperature

external heat transfer coefficient

ECONOMIC THICKNESS

The most substantial return on an investment ininsulation is in energy savings over a period of time

Thermal insulation is one of the most if not the most

significant technology used to conserve energy thereby

reducing pollution Rising energy costs guarantee an

increasing return on any investment made in insulation

In fact it costs less to insulate than not to In the case

of steam process and heat the difference in capital

investment necessary to provide equipment for the

extra steam capacity needed on underinsulated systems

and that investment necessary to insulate plus the

cost of insulation still represents a significant capital

investment savings That insulation saves money is not

the issue here The issue is how much

Economic thickness calculations are based on the law

of diminishing returns Because no insulation material

can completely stop the flow of heat each increment ofinsulation added to the thickness saves only a percentage

of the heat which has escaped through the underlying

insulation Therefore each increment of insulation

saves less than the one before it and must be evaluated

against the cost of installation to determine if it is a

ldquogood investmentrdquo It is possible to determine how much

insulation applied to a given system will repay its initial

costs in a specified time This point is reached when the

cost of the last incremental of insulation added is offset

by the savings generated by that increment

Refer to the stetch on the left The vertical scale is the

annual cost The horizontal scale is insulation thickness

As the insulation thickness increases from 0 the cost of

heat loss through the insulation decreases Note that this

cost (line B) tends to approach a horizontal line at high

thicknesses As the insulation thickness increases the

cost of the insulation also increases (line A) The total

annual cost at any insulation thickness is the sum of the

cost of the insulation and the cost of the lost heat (line

C) Line C goes through a minimum value of total annual

cost at the Economic thickness

With thicknesses less than the economic thickness the

total annual cost is higher because of the higher valueof the cost of lost heat With thicknesses higher than

the economic thickness the total annual cost is higher

because of the higher value of the cost of the insulation

In the case of computer results each pipe size will be

listed with the recommended thickness as well as

the average heat savings (as compared to a pre-listed

thickness or bare surface whichever chosen) and the

present value of the heat saved

In order to use any of the available manuals tables

or computer programs the two cost factors (cost of

lost energy and cost of insulation) must be found Thefollowing data is generally provided by the investor

Cost of lost energy

This factor is derived from the combination of the

rate of energy transfer the cost of energy and the

operational hours per year of the building Computing

the rate of energy transfer requires surface and

ambient temperatures thermal conductivity of the

chosen insulation the maximumminimum thickness of

insulation to be considered surface emissivity and last

but not least consideration of surface orientation (i evertical horizontal) and wind (air) velocity

Cost of insulation

This factor is derived from computing a bdquounit installed

price of insulationldquo with the total cost annualized overthe projectacutes life The unit installed price is a combination

of the cost of materials cost of labor and worker

productivity This is a sensitive variable in the economic

thickness calculation Only the roughest of regional

averages are available As a result care must be taken not

to perceive these estimates as fixed budget prices used

for installing insulation Material prices are related to the

volume and cost of the insulation jacketing securement

finishing and structural support material used Also

included in this figure are storage and handling costs to

the contractor Labor costs vary regionally and include

wages fringe benefits per diem and travel expensesas well as overhead and profit Labor production varies

with pipe size complexity number of layers necessary

accessibility of piping and surfaces type of materials

used and general working conditions Other costs

involve the job size and increase with the magnitude of

the job They include the preparation scaffolding clean-

up and tear-down costs supervision costs and general

overhead

MAXIMUM SERVICE TEMPERATURE

MST is determined in a laboratory by testing under de-

fined conditions which are dependent upon the form

of delivery and which are laid down in EN 14 706 (for

wired or lamella mats slabs and felts) and EN 14 707(for pipe sections and segments) MST is determined

by establishing the temperature and time related de-

crease in thickness in one-sided heating For the test

the sample shall take a load of 500 Pa The sample is

heated with a transient of at least 5 Kmin The hot-

face temperature must be maintained for 72 hours at

the expected maximum service temperature At the

maximum service temperature no test result must dis-

play a deformation under load of more than 5

In data sheets of different producers (not only mineral

wool) you will often find MST and value which is not

measured accordance to EN 14 706 This temperature

is only assumed When using such temperature there

is a danger of insulation degradation mainly insulation

thickness If mineral wool product has MST 700 or 750 degC

in its data sheet you can be sure that the material will

not withstand such temperature without degradation

of assessed properties Such temperatures shall not

be used Producers should leave field of assumed MST

and test their products to be able to use declared

MST according to EN 14 706 It is an outstandingimprovement compared to the past because individual

products on the European market can be compared to

each other according to standards valid in the EU

Slabs wired and lamella mats Orstech are certificated

according to valid European standards they are

regularly tested in testing laboratory FIW Muumlnchen

according to VDI 2055 and AGI Q 132 Maximum service

temperatures for various products can be found at the

end of the catalogue in the chapter Isover Products on

page 21)

EVAPORATION OF BINDERS

Binders and greasing agents in mineral wool products

dissolve and evaporate in areas with temperatures

higher than 150 degC Binder evaporation does not have any

influence on thermal properties only the compactness

of a material is decreased If proper underconstruction

is made there is almost no danger of insulation slide

down But if too small insulation thickness or improper

type of insulation is used (mostly insulation with too

low density for too high temperatures) danger of binder

evaporation in the whole thickness is possible with

consequent insulation slide down In this case no well

made underconstruction will help Insulation will not

work any more In the outer colder areas no dissolution

and evaporation take place

FIRE PERFORMANCE

FIRE ndash a chemical reaction involving rapid oxidation or

burning of a fuel occurs only when three elements are

present in the proper conditions and proportions

FUEL ndash Fuel can be any combustible material - solid

liquid or gas Most solids and liquids become a vapour

or gas before they burn

OXYGEN ndash The air we breathe is about 21 oxygen Fire

only needs an atmosphere with at least 16 oxygen

HEAT ndash Heat is the energy necessary to increase the

temperature of the fuel to a point where sufficient

vapours are given off for ignition to occur

Fire development depends mostly on room geometry

and ventilation the fuel type the amount and surface

area of the fuel Fire is often discussed in terms of the

temperature development and can be divided into

different stages incipience (ignition) growth flashover

fully developed fire and decay

How materials behave in the early stages of a fire from

ignition to flashover (the spontaneous ignition of hot

smoke and gasses) needs to be assessed at the design

stage for buildings and also for plants and equipment

Euroclasses a new European harmonised classification

system for materialsrsquo reaction to fire in most Europeancountries replaced the old national standards The

Euroclass fire classification covers not only materials

used in building structures but it is being extended also

to technical insulations to cover building equipment

and industrial installations This will help to compare

the reaction to fire of different thermal insulation

materials

The classification levels are A1A2 (completely non-

combustible) B C D E and F A1A2 corresponds to

the safest situation E would be the most dangerous

situation and F would mean not classified

ISOVER mineral wool insulations are totally non-

combustible and completely fire safe achieving

Euroclass A1 fire rating (A2 for products with facing)when classified in accordance with EN 13501-1 One

of the most important issues studied under reaction to

fire performance is the potential for flashover to occur

which can lead to a fire spreading uncontrollably Isover

stone wool is not susceptible to flashover

This is a guide to common building materials and their

likely Euroclassification

Check with individual product manufactures for spedific

product specifications

REACTION TO FIRE

Smoke and flaming droplet risk(1) In the EU classification system for reaction to fire

a construction product will be classified as Euroclass A1

A2 B C D E or F depending on its tendency to burn

(2) The product testing will provide data represented

by the signs s1 s2 or s3 which indicate the tendency

to release smoke Smoke causes over 60 of deaths in

fire across the EU The measurement of smoke release

has been put into these 3 broad bands that can be

translated as ldquolittle or no smokerdquo s1 - rdquoquite a lot of

smokerdquo s2 - rdquosubstantial smoke releaserdquo s3

(3) Some construction products like these made of

polystyrene can melt and ignite to form Flaming

Droplets Wooden products on the other hand will tend

to char before the char falls away as Flaming Particles

to expose more material

These rdquoflaming dropletsparticlesrdquo will tend to

initiate new fires away from the original point of

ignition and must be considered when the products

are used horizontally in ceiling or roof applications

The classification system ranks the level of release of

FIRE PROTECTION DESIGN FOR VENTILATION DUCTS

Produced with the stone wool technology of Isover

fire protection system ORSTECH Protect is mineral

wool that combines all the advantages of conventionalthermal and acoustic insulation with top level of fire

safety Mineral wool insulations have the melting point

higher than 1000 degC From the fire protection point of

view products Isover are one of the safest materials

ORSTECH Protect consists of slab or lamella mat

solutions offering up to one hour fire protection for

both vertical and horizontal applications of rectangular

and circular ductwork systems

Passive protection of ventilation ducts is possible by

two basic means

Installed a fire damper into the duct to the place of

fire separation

Use a fire protection insulation system which is

tested according EN 1366-1 and has a classification

protocol in accordance with EN 13 501-3 This second

case is covered by insulation system ORSTECH

Protect

LEGISLATION

Air duct which shall resist the spread of fire from one

compartment to another is tested according to EN

1366-1 The standard can be applied to vertical and

horizontal ducts with or without branches for fire inside

or outside the duct The test measures the time period

for which ducts of specified dimensions suspended as

they would be in practice satisfy criteria when exposed

to fire from inside or outside (separately)

This standard is used in conjunction with EN 1363-1

which prescribes requirements for the determinationof fire resistance of various components of building

structures which are exposed to standard fire

conditions In this standard there are failure criteria

whereby it is possible to evaluate the ability of a tested

duct to prevent fire spread due to the destruction of

the duct (integrity failure E) heat transfer (insulationfailure I) and prevention of the smoke penetration

(smoke leakage S) Fire protection is expressed by time

in minutes for which failure criteria are fulfilled

Designation itself is then done according to

classification standard EN 13 501-3 Classification

states if criteria are fulfilled for fire outside (marking

o rarr i) valid for duct type A or fire inside (marking

irarr o) or from both directions (iharr o) valid for duct type

B and if this is valid for a horizontal duct (marking ho)

or a vertical one (ve) or both (ve ho) Eg class bdquoEI 30 S

ndash ve ho (orarr i) Sldquo represents duct capability to maintain

integrity insulation and smoke leakage for time period

of 30 minutes under fire exposure from outside both

for vertical and horizontal positions

MAXIMUM DUCT SIZES

Maximum size is according to EN 1366-1 for rectangular

duct 1250 x 1000 mm and for circular duct up to

diameter 1000 mm If a duct has bigger dimensions the

classification protocol cannot be used

ACOUSTIC PERFORMANCE

Noise is a sound which impacts negatively on the

surroundings Noise levels emanating from HVAC

services (pipework ductwork and air handlingequipment) and other services can be significantly

reduced with the use of Isover products which will

help to achieve acceptable environmental noise levels

Isover insulations are due to its fibre structure an ideal

material for sound attenuation not only for industrial

application The degree of sound insulation will depend

upon the application the thickness of insulation used

and the nature of any finish used to clad over the

installation In suitable frequencies they can absorb up

to 95 of the sound energy (α = 095)

SOUND ABSORPTIONWhen a sound wave strikes a surface the sound energy

is broken down into transmitted energy (through the

material) converted energy (usually heat) and reflected

energy (back towards the source of the sound)

The more absorbent the material the less sound is

reflected That part of sound energy which is converted

and transmitted is usually expressed as an absorption

coefficient α

The absorption coefficient for a material varies with

the frequency An absorbent layer of mineral wool

has the best absorption capacity in medium and high

frequencies The absorption in low frequencies is

improved by increasing the thickness or by providing an

air gap behind the absorbent layer

Examples of the effectiveness of Isover products in noise

control are given in the following table

ABSORPTIVE STRUCTURES

The most common task in room acoustics is to attenuate

or cancel some frequencies or a whole frequency band

This is possible to realise by using convenient absorptive

material or structures which are frequency-dependent

In this way we can control not only absorption ie

reverberation time but also suppress or completely

remove unpleasant sounds

In a porous material acoustic absorption is mainlycaused by friction in pores ie friction between

oscillating particles and the surface of pores Since the

energy loss due to friction is proportional to the length

of the path the most absorption will occur when the

porous material is placed in a position where the particle

displacement is the largest (maxima displacement)

When sound strikes a rigid wall like concrete for

example a standing wave result and the maxima of

particle displacement appear at the distances λ14

critical distances which must be covered by adsorbers

ie layers with thicknesses d1 = λ

14 d

2 = 3λ

24 d

3 = 5λ

34

In short an absorber with a thickeness d placed directly

on the solid structure will effectively attenuate only

those frequencies where f ge c4d (c is the velocity of

sound 340 ms) For example insulation thickness

of 50 mm wil l reliably attenuate frequencies higher

than 1700 Hz thickness 100 mm then already from

frequencies 850 Hz The higher the frequency the

shorter the wave length and better attenuation

An absorbing layer tightly adjacent to a solid structure

has nevertheless one disadvantage To attenuate

low frequencies it would be necessary to use verythick layers (for example for attenuation of 500 Hz a

thickness of about 20 cm would be necessary) Therefore

acoustic tiles can hardly attenuate low frequency noise

(frequencies lower than 100 dB such as noise from

discotheques)

Fortunately it is possible to avoid expensive acoustic

tiles with high thickness If we use a very thin layer

and place it just in the position of the displacement

maximum of a chosen frequency this chosen frequency

and its odd multiples will be attenuated Acoustic

tiles thus work as a selective frequency filter On theselective basis also other acoustic attenuators work

namely membranes oscillating plates and resonators

ACOUSTICS INSULATIONS

Isover stone wool products with a high longitudinal air-

flow resistance (up to 95 kPasm2) and uniform porosity

(93 ndash 99 ) are used as sound attenuation insulations

In suitable frequencies they can absorb up to 95 of

the sound energy (α = 095) Sound attenuation in a

construction is related to elastic properties of Isover

mineral wool insulations and their low modulus of

elasticity (they have low dynamic toughness and

therefore they are much more suitable for acoustic

purposes in comparison with foam plastics)

Sound attenuation properties of Isover products are

characterised by an absorption coefficient α which

can be found in the table for three thicknesses andsix frequencies According to a given noise spectrum

it is possible to design a sound attenuation structure

of which our material is only a part Since we provide

only insulation material we launch only absorption

coefficients Final attenuation will be dependent on

the whole designed construction (considering also

supporting construction hangers) and assembly

Isover does not design sound attenuation and thus it

is necessary to ask specialists who are able to design a

proper structure

Generally we can say that transmission loss is higher

for constructions with higher plane weight therefore

in most cases insulation with higher density has

better sound attenuation (eg slabs Orstech 65 90

110 Isover FireProtect 150) than insulation with lower

density (eg Orstech 45) Slabs can be manufacturedwith a facing ndash glass black tissue

GENERAL RULES FOR USING ISOVER INSULATIONS

Between insulated piping sufficient distances must

be kept

Valves should be placed without needing to go on theinsulated pipes when handling them

Spindle of valves should not be installed in an upward

direction to avoid water leakage into the insulation

Surfaces before insulating must be clean and dry It

is not possible to insulate wet or frostbitten surfaces

which may later cause damages of insulation or

insulated surfaces

Dirt and rust must be rubbed down from untreated

carbon steels

Smear and oils must be removed by detergents or

solvents from insulated surfaces

Stainless steel surfaces must not be cleaned by

detergents or solvents with chloride content They

may be cleaned only by stainless steel brushes

Chloride solution attacks stainless steel surface and

causes stress corrosion cracking in the material With

increasing surface temperature the danger of stress

corrosion cracking is raised

Piping and equipment from stainless steel can be

insulated only by mineral wool insulation in AS

quality Such material can have maximum content

of chloride ions of 10 mg in 1 kg of the insulation

material

It is necessary to avoid contact of metals which can

cause galvanic corrosion (Cu-Zn Fe-Al)For operating temperatures higher than 600 degC

aluminium jacketing should not be used

Self-tapping screw bold or rivet should be from the

same material as the jacketing

Surfaces with temperatures higher than 500 degC

should be insulated by more insulation layers in a

way that each layer has a different apparent density

Material with higher density insulates better under

higher temperatures than material with lower

density therefore insulation with higher density is

placed closer to the hot side Under low operating

temperatures thermal performance is almost equalSafety working principles must be kept for insulation

assembly

Isover products are packed into PE foil They must be

transported in covered vehicles under such conditions

to avoid moistening or other degradation They must

be stored in covered places

Wired mats

After the cutting of needed length the wired mat shall

be tightly wrapped on the pipe Wired matsrsquo butt jointsshould be in close contact to each other to ensure no

gaps between mats For multiple layer construction

each layer is staggered when applied Each layer must

be secured in place before the next is applied Individual

mats are bound together with a wire with minimal 07

mm thickness Alternatively wired hook or stainless

steel bands (with minimum width of 10 mm) can be

used Maximum distance between hooks is 150 mm

The decision to use multiple layers may be made for one

or more of the following reasons

to provide compensation for pipe expansion andcontraction

to reduce heat flow by staggering joints thus creating

a more thermally efficient installation

to achieve thickness in excess of manufacturersrsquo

capabilities

Lamella mats

Lamella mats Orstech LSP H consist of mineral wool

lamellas which have been glued to aluminium foil

reinforced with a glass fibre grid and these fibres are

predominantly perpendicular to the surface of themat Compressive strength but thermal conductivity

too are increased compared to mats with a fibre

orientation parallel to the surface (wired mats) Due

to its compressive strength resistance they have less

demands for undeconstruction (less thermal bridges)

in comparison with wired mats Temporary securing in

place is done by aluminium tapes final fixing shall be

done by a baling wire

Protective coverings

The efficiency and service of insulation is directly

dependent upon its protection from moisture entry andmechanical and chemical damage Choices of jacketing

materials are based upon the mechanical chemical

thermal and moisture conditions of the installation

as well as cost and appearance requirements The

basic function of the weather protection is to protect

the insulation from rain snow sleet wind solar

radiation atmospheric contamination and mechanical

damage With this definition in mind several service

requirements must be considered

PIPING INSULATION

For domestic hot water piping with smaller diameters

insulation pipe sections which are covered withaluminium foil are ideal Pipe sections with a facing

have a self-adhesive overlap in a longitudinal joint

to ensure perfect enclosure of a pipe section It is

recommended to secure pipe sections by an aluminium

tape or by galvanized wire transversely They are usually

knotted three times per meter more for pipe sections

with higher diameter Higher diameters should be

secured either by wire or by metal band (at least two

bands per meter)

Pipings with bigger diameters are most commonly

insulated by lamella mats Orstech LSP (stone woolinsulation) or Isover ML-3 (glass wool insulation)

eventually by wired mats Orstech DP (especially for higher

temperatures) Lamella and wired mats are also suitable

for appliances and vessels (both ends and cylindrical

parts) residential heating systems and air ducts

Internal mechanical forces ndash expansion and contraction

of the pipe or vessel must be considered because the

resulting forces are transferred to the external surface ofthe weather barrier Ability to slide elongate or contract

must be provided

External mechanical forces ndash mechanical abuse (ie

tools being dropped abrasion from wind-driven sand

personnel walking on the system) inflicted on a pipe or

vessel needs to be considered in design This may affect

insulation type as well as the weather barrier jacketing

type

Chemical resistance Some industrial environments may

have airborne or spilled corrosive agents that accumulate

on the weather barrier and chemically attack the pipe or

vessel jacketing Elements that create corrosive issues

must be well understood and accounted for Insulation

design of coastal facilities should account for chloride

attack

Galvanic corrosion Contacts between two different

types of metal must be considered for galvanic corrosion

potential Similarly water can act as an electrolyte and

galvanic corrosion can occur because of the differentpotential of the pipe and vessel and a metal jacketing

Materials used as weather barriers for insulation

Typical metal jacketing materials bare aluminium coated

aluminium stainless steel painted steel galvanized steel

aluminium-zinc coated steel

Typical polymeric jacketing materials polyvinyl chloride

(PVC) polyvinyliedene chloride (PVDC) polyisobutylene

multiple-layer composite materials (eg polymericfoil

mesh laminates) fabrics (silicone-impregnated fibreglass)

Fittings valves

Insulation of fittings valves flanges and couplings is

the most time consuming and often expensive aspectof commercial and industrial insulation But it is crucial

to insulate also these parts properly otherwise most of

energy will be transported by these thermal bridges For

example for 200 degC medium heat loss of one uninsulated

valve corresponds to one meter of uninsulated pipe or

ten meters of uninsulated pipe

Fittings are items used to change size direction of flow

level or assembly of piping They may be of the screwed

sweat or welded types Valves are any of various devices

that regulate liquid or gas flow and they may be of the

screwed sweated flanged or welded types Flanges areprotruding rims and edges of the screwed or sweated

type used with fittings valves couplings etc And finally

mechanical couplings are devices used in assembly of

piping Screwed and flanged connections on fittings

valves couplings etc usually require oversized insulation

applications to compensate for the protrusions

Minimum spacing between pipes and

constructions

It is essential to ensure sufficient space between pipies

and between a pipe and a wall (minimally 100 mm)

Otherwise there is a great danger of creating a zone withalmost no cenvenction The result can be too high surface

temperature (needed personal protection against burn)

or possibility of condensation on cold piping Besides

mounting would have been more difficult

DUCTING INSULATION

Isover products are designed to provide high levels of

thermal acoustic and fire protection insulation in HVACductwork applications such as rectangular flat oval and

circular ductwork

The most suitable insulation materials for ducts are

felts KLIMAROL with aluminium foil facing lamella mats

Orstech LSP or Isover ML-3 wired mats Orstech DP or

slabs Orstech H with aluminium foil facing

Duct insulation mounting

Insulation is mostly fixed to the duct by welded pinsWhen using Orstech H slabs with aluminium facing all

the joints shall be sealed with aluminium tape If a steel

clamping band is used it is necessary to use thin-walled

steel L-profiles to avoid trimming of the insulation If

using Orstech slabs without aluminium facing or Orstech

DP wired mats proper jacketing shall be made (the most

suitable is metal steel jacketing)

FIRE PROTECTION OF VENTILATION DUCT

Description

It is vital to develop safe durable and reliable solutions

for ventilation systems as fire can easily spread from the

point of origin via ductwork Isover meets the highest

standards for fire protection providing excellent fire

resistance and top-rated reaction to fire performance

Rectangular ducts shall be insulated by Orstech 65 H

slabs with 40 mm thickness (60 mm for fire resistance EI

60 for a horizontal duct) circular ducts shall be insulated

by Orstech LSP PYRO lamella mats with 50 mm thickness

By these solutions fire resistances EI 15 30 45 and 60 S

have been certified to comply with EN 1366-1

Orstech system with fire resistance has been proven to

meet the requirements of all possible scenarios for fire

from the outside The scenarios can be identified by duct

orientation and duct shape (see table below) Horizontal

ducts normally serve one floor of a building Vertical

ducts normally serve between floors of a building All

scenarios have been done only with one layer Insulation

is fixed to a duct by welded pins Such solution is time

and material saving

Metal ductworkThe steel duct is constructed in sections of galvanised

steel sheet or stainless steel sheet minimum 08 mm thick

(standard duct sheeting for rectangular ducts specified

in DIN 24190 for circular ducts in DIN 24145) Maximum

duct size for which classification protocol is valid is 1250

mm (width) x 1000 mm (height) for rectangular duct or

diameter up to 1000 mm for a circular duct

At each cross joint flanges are fastened to the duct

with spot welds at 150 mm nominal centres

Use a ceramic tape gasket and fire-stopping mastic

between the flanges to seal the joints

Flanges are bolted together with an M10 steel nut

and bolt at each corner

Fasten the flanges together with steel clamps with

bolts M8 (see the figure) in quantity of 3 clamps per 1

meter of the flange length

Drop rods and hangers

Rectangular ducts are suspended by threaded rods and

channel section bearers A duct shall be hung with asuspension system which is independently fire rated

according to EN 1363-1 Certificated suspension system

MUPRO is recommended for the purpose Each steel

hanger consists of two threaded drop rods minimum

M10 and a channel section bearer 3840 mm Fasten

the bearer to the drop rods using hexagonal nuts and

washers The drop rods can be positioned either inside

the insulation material or outside If drop rods are outside

there is no need to insulate them separately The bearers

are positioned inside the insulation material

Circular ducts are suspended by MUumlPRO steel hangerswhich consist of two threaded drop rods minimum

M10 and a two-part industrial circular band The ends

of each band section are bent outwards Fasten the band

sections together and attach them to the drop rods with

hexagonal nuts and washers Place these hangers inside

the insulation The rods do not need to be protected by

insulation

When fixing them to a concrete construction use all-

steel expanding anchors to fasten the threaded rod

hangers to concrete soffits The anchors should penetrate

the concrete by at least 60 mm When fixing to a steel

supporting construction drill a hole through the steel

member allowing the drop rod to be supported by a steel

nut and washer above If a clamp type fixing is used the

clamp must be steel suitable for the purpose It should

pass around the steel member and be fastened back on

itself Clamps that rely on friction to hold them in place

are not suitable

Insulation

Rectangular ducts are insulated by Orstech 65 H slabs

(with apparent density 65 kgm3 and with one-sidedaluminium foil facing) with 40 mm thickness (60 mm

for fire resistance EI 60 for a horizontal duct) Circular

ducts are insulated by lamella mats Orstech LSP PYRO

with 50 mm thickness Insulation slabs (lamella mats)

need to be cut to fit the duct as tightly as possible the

insulation may need to be cut to fit around flanged duct

joints Install the insulation so that one slab (lamella

mat) is adjacent and tightly fitted against the other No

gaps must be present between butt joints of insulation

Insulation can be easily cut with a standard laggers knife

There is no need for adhesive on joints All the joints shall

be sealed by aluminium tape For rectangular ducts in theposition of flange the slabs are snick first 15 mm of the

thickness to avoid lifting of the slabs Butt joints should

be positioned out of flanges Fire protective insulation for

circular ducts does not require usage of a wire net mesh

on the outer side of insulation

Stud welded pins

The insulation is fixed to the duct using steel pins 27 mm

to 3 mm nominal diameter and spring steel washers

minimum 30 mm diameter The length of pin should

be equal to the insulation thickness The orientational

number of pins is 16 piecesm2 for rectangular ducts and14 piecesm2 for circular ducts

Recommended distance from duct edges and joints is

80 mm 50 mm from flanges

Wallfloor penetration

At wallfloor penetration one must insure the same fire

resistance of ventilation duct as has the fire separation

to avoid the spreading of fire from one compartment to

other via a duct This is possible by two basic principles

or their combinations - install a fire damper at the

penetration point or use insulation with fire resistancewhere the crucial thing is the fire-stopping The fire-

stopping is from the second insulation layer with the

width of 150 mm from both side of fire separation

The same general principle is used for both rectangular

and circular ducts regardless of orientation Place

the duct in the penetration of the construction with

approximately 10 mm gap between insulated duct and

opening Before installing the fire-stopping with the

same insulation thickness as is used for the first layer

pack the space between the duct and partition with

as many pieces of insulation as possible Ensure tight

compression in order to completely fill the opening This

must be done because system ORSTECH Protect does

not require stiffeners inside the duct Then install thesecond insulation layer so that it is adjacent and tightly

fitted against the penetration The insulation must be

cut leaving excess length so that it exerts some pressure

between the penetration and the last fitted piece of

insulation

The second layer is fixed by welded pins with length

equal to double insulation thickness The second layer for

circular ducts (lamella mats) is clamped with 1-2 wires

with a diameter 16 mm Then the insulation is secured

to the duct by welded pins

A inovative solution is the considerable simplification of

a fire-stopping concept There is no need to use any kind

of stiffener either inside or outside of the duct A great

advantage is to mount the whole ventilation section

at once and the wall itself can be placed anywhere

Therefore the position variability of fire separation is

provided No glue or mastic is needed at wallfloor

penetrations

Fire classification

ORSTECH Protect insulation with fire resistance has

been tested by the fire testing laboratory Pavus as an

authorised body AO 216 Classification protocols on the

request

Fire protection system ORSTECH Protect has been tested

in accordance with EN 1366-1 Maximum size for the

rectangular duct is 1250 x 1000 mm and for the circular

duct up to diameter 1000 mm If a duct has bigger

dimensions the certificate connected to the standard

cannot be used

to provide compensation for pipe expansion and

capabilities

for retrofitting purposes

Insulation is usually fixed by mechanical fasteners - by

studs or pins Spacing between them is dependent on the

design of the vessel its surface temperature fire hazard

potential involved and presumptive loading Each slab

should be fixed by minimally two pins

BOILER INSULATIONInsulations for boilers kettles and ovens are one of

the most demanding applications in industry because

these units are operating at very high temperatures

Good insulation not only saves energy considerably but

the main purpose is personal protection against burn

According to the surface shape and temperature are used

either slabs with higher densities Orstech 65 to 110 (for

boilers with flat surfaces) or wired mats Orstech DP 65 to

DP 100 (for boilers with cylindrical parts)

Boiler walls are exposed to very high temperatures

(usually around 500 or 600 degC) Therefore it is essential

to use mechanical fasteners for the fixing of insulation

to the surface Insulation for boilers is done in at least

two layers each layer must be staggered when applied

Each layer must be secured in place before the next is

applied A product with high density should be placed as

the first layer because it has a higher maximum surface

temperature (higher resistance against high operating

temperatures) and better insulation performace than

products with lower densities

CHIMNEY INSULATION

Insulations for prefabricated chimneys are directly

supplied by producers of such systems In cooperation

with specialized wholesale companies we offer slabs

with multi-plate stripes which allow easy and perfect

application for prefabricated chimneys suitable both

for stainless steel chimney liners as well as with other

brands of chimney lining systems The main advantage

is the time saving during the installation in comparison

with the use of lamella mats and horizontal orientation

of fibres (better thermal conductivity) Insulation

dimensions ie thickness of slabs and groove dimensions

dependent on the chimney diameter are supplied

according to customer needs

For non-prefabricated chimneys are mostly used wired

mats Orstech DP or slabs Orstech 90 or 110 (for chimneys

with rectangular cross-section)

TECHNOLOGICAL APPLIANCEINSULATIONWhere big quantities of energy is used eg within

petrochemical paper and pulp industries thermal

insulation is necessary in order to reduce expensive

energy losses Tanks vessels exhausts exchangers

and technological piping are appliances that are often

working at high temperatures Good insulation will save

energy considerably which will benefit the environment

and keep the working costs down At the same time

the insulation will reduce temperature fall which could

disturb the production process

Proper insulation can be chosen in accordance with

dimension surface temperature the manner of fixing

and requirements for jacketing For pipes and cylindrical

parts are used lamella mats Orstech LSP H and Isover

ML-3 (only for temperatures up to 250 degC) or wired mats

Orstech DP For appliances and vessels with rectangular

shapes Orstech slabs are suitable (type according to a

surface temperature) Slabs can have aluminium facing

If insulation is done in more than one layer each layer

is staggered when applied Each layer must be secured

in place before the next is applied The decision to use

multiple layers may be made for one or more of the

following reasons

AS QUALITY

Corrosion of stainless steel surfaces under insulation

is an often discussed issue Highly alloyed austenitic

steel (alloyed by chrome nickel and molybdenum) are

predisposed to tensile stress corrosion (stress corrosion

cracking) which is caused by chloride ions Austenitic

is a description of crystalline steel structure therefore

identified as AS Chlorides with water (well-known

is classical salt) attack steel surface and cause cracks

in the material With increasing surface temperature

the danger of stress corrosion cracking is raised To

minimise this danger mineral wool insulations in AS

quality are available for this application Standard AGI

Q 132 determines maximum content of chloride ions of

10 mg in 1 kg of the insulation material Mineral woolinsulations may be used for insulating objects made

of stainless austenitic steels if the content meets the

requirement Isover stone wool technical insulations

meet the requirement of AGI Q 132

THERMAL CONDUCTIVITY

One of the most important parameters of insulations is

their thermal conductivity named lambda value λ [W

(mK)] Thermal conductivity measures the capacity of a

material to lead or to resist heat transfer The smaller

the lambda value the better the thermal insulation

The thermal performance of mineral wool is achievedthrough the entrapment of air within the material Its

thermal conductivity does not deteriorate over time

For slabs mats felts and loose mineral wool the

thermal conductivity is determined in the hot box

tester according to EN 12 667 The determination of the

thermal conductivity of sections is in the pipe tester

according to EN ISO 8497 For lamella mats and wired

mats the thermal conductivity is measured in the hot

box and in the pipe tester The thermal conductivity of

mineral wool insulations has to be determined up to the

maximum service temperature (hot face) as a function

of the mean temperature (arithmetic mean betweenobject and surface temperature)

The thermal conductivity varies with temperatures and

with densities The higher the density the higher the

thermal performance at high temperature surfaces In

our product data sheets declared lambda-values λD

are

used these values are fulfilled within every product

A designer will be on the safe side when using our

declared lambda-values That means allowances for

workmanship spacers and supporting constructions

are made Possible inaccuracies caused by calculation

equations can be eliminated

MELTING POINT OF MINERAL WOOL

PRODUCTS

The melting point of mineral wool is determined

according to DIN 4102 part 17 It is a parameter for

the durability of mineral wool insulations in building

components in case of fire It must not be confused

with the maximum service temperature and has no

relation to the service temperature Mineral wool

insulations have the melting point higher than 1000 degC

usually in the range from 1200 to 1600 degC

MAXIMUM SERVICE TEMPERATURE

Maximum service temperature according to EN 14 706

(for wired mats lamella mats and slabs) and EN 14 707

(for pipe sections) ranging from 250 to 700 degC MST for

various products can be found in a Product data sheet

or at the end of the catalogue in the chapter Isover

Products on page 23

FIRE RESISTANCE

Mineral wool products Isover are completely non-

combustible they resist to high temperatures and thus

prevent fire spread The classification levels according

to EN 13 501-1 are A1 possibly A2 for materials with

a facing

ACOUSTIC PROPERTIESIsover mineral wool products have a fibre structure

and therefore reach excellent noise attenuation for

example from HVAC services (pipework ductwork

and air handling equipment) and other services An

absorbent layer of mineral wool has the best absorption

capacity in the medium and high frequencies (under

such conditions it can have absorption coefficient up to

98 (α = 095)) The absorption in the low frequencies

is improved by increasing the thickness or by providing

an air gap behind the absorbent layer

RESISTANT TO BIOLOGICAL PESTSMineral wool insulation is resistent to wood-destroying

pests rodents and insects They are rot-proof and do

not sustain growth of mould

LOW THERMAL EXPANSION

Mineral wool insulations have almost zero thermal

expansion with changing temperatures

MOISTURE AND WATER REPELLENCE

All Isover products are treated during manufacture with

special additives which make them water repellent

BASIC FUNCTIONS OF TECHNICAL INSULATIONS

Insulations are defined as those materials which retard

the flow of heat energy by performing one or more of

the following functions

Energy conservation minimizing unwanted heat loss

gain from building HVAC systems as well as preserv-

ing natural and financial resources

Personnel protection controlling surface tempera-tures to avoid contact burns (hot or cold) ndash maximum

surface temperature criterion

Condensation control minimizing condensation by

keeping the surface temperature above the dew point

of surrounding air

Prevent internal condensation in pipes

Process control minimizing temperature change in

process fluids where close control is needed

Increase operating efficiency of heating ventilating

cooling plumbing steam process and power systems

found in commercial and industrial installations

Freeze protection minimizing energy required for

heat tracing systems andor extending the time to

freeze in the event of system failure Freeze protec-

tion of vessels and tanks with various accumulated

fluids or fuels

Noise control reducingcontrolling noise in mechani-

cal systems

Fire safety protecting critical building elements and

slowing the spread of fire in buildings

The application of thermal insulation on pipe vessels

and ducts is recognized as a necessary requirement in

any construction activity The thickness and extent of

insulation required has always been subject to arbi-

trary and imprecise decisions with little engineering or

economic input No material incorporated in a modern

construction project provides the owner with as good

a financial return throughout the life of the facility as

does insulation

The investment in insulation may protect the equip-

ment and personnel present during the life of the facil-

ity Proper insulation prevents condensation chemical

corrosion and excessive heat in fire hazard areas Added

human comfort provided by proper insulation in hotelsoffice buildings schools or factories adds considerably

to the value of the facility and productivity of its per-

sonnel Process temperatures in heat traced piping are

more efficiently maintained with proper insulation The

size of the heat generating equipment can be reduced

when designed with an efficient insulation system In

some cases insulation is essential to an industrylsquos very

existence as with the power the process and

the cold storage

However the most substantial return on an investment

in insulation is in energy savings over a period of timeThese savings are becoming more and more empha-

sized in the industrial insulation field as energy costs

rise coupled with the fact that industrial plants and

utilities usually account for about half of the total en-

ergy consumption

Recently the environmental impact of new renovated

or relocated industrial and commercial facilities has

taken on new importance Thermal insulation is one of

the most if not the most significant technology used

to conserve energy thereby reducing pollution Besides

minimizing heat loss insulation increases process ef-

ficiency helps maintain employee safety comfort and

production

For their thermal protection of various industrial appli-

cations it is a necessity to design and use such insula-

tion material that meet operating conditions Isover will

help you find the most suitable insulation product for

given application

HEAT FLOW TRANSMISSION

Heat transfer is carried out by three heat transmission

modes conduction convection and radiation

Conduction

Heat transfers from warmer surface to colder through

solid material or gas (by fibres in mineral wool

insulations) The more insulant the material the less

the conduction

Convection

Transfer of heat caused by air movements (because of

temperature and density gradient) Hot air moves up

and heat dissipates The quieter the air the less the

convection Convection can be natural (when calculating

insulation inside the building) or forced (for calculation

outside where wind blows)

Radiation

Each material absorbs or emits thermal radiations

depending on its temperature and its emissivity Unlike

conduction or convection heat can be transferred by

radiation also in a vacuum When radiation is absorbed

or reflected there is less thermal transfer Measure of

radiating capacity of a material is emissivity ε Absolute

black body has the highest emissivity (ε = 1) Rough

and dark surfaces approaches such value (for example

mineral wool insulation without jacketing ε = 094)

contrary to bright and smooth surfaces that have very

low emissivity (for example polished aluminium foil ε

= 005) For design it is necessary to take into account

that covering of the bright surface with dust will

increase emissivity significantly

These three transport mechanisms are applied in

two very important quantities ndash surface heat transfer

coefficient α and thermal transmittance U

Thermal insulations impede conduction convection and

radiative effects

by creating a thermal barrier against conductionby suppressing air movements

by limiting radiative effects

Surface heat transfer coefficient

Two heat transmissions (convection and radiation)

influence the heat transfer coefficient α [W(m2middotK)] The

higher the heat transfer coefficient the higher the heat

flow rate from a warm surface

Thermal transmittance

Thermal transmittance (also called Overall heat transfer

coefficient) U (for flat surfaces [W(m2middotK)] for pipes [W

(mmiddotK)]) is inverted value of thermal resistance and it

takes into account the influence of all heat transmission

modes (conduction convection and radiation)

INSULATION SYSTEM DESIGN

GENERAL

An insulation system is the combination of insulations

finishes and application methods which are used toachieve specific design objectives Among these are

Energy savings

Reduced operating costs

Condensation control

Chemical compatibility with the metals being

insulated the atmosphere to which the system

will be exposed and the various components of the

insulation system itself

Protection of mechanical and insulation systems

from mechanical abuse and atmospheric damage

Personnel protection

Fire protection

Sound control

Future requirements for access to piping fittings etc

Accommodation to limited clearances or work space

While there are several choices of insulation materials

which meet basic thermal and cost-effective

requirements of an installation choices become more

limited with each additional design objective that

comes into play

INSULATION THICKNESS CALCULATION

When calculating the thickness of the insulation it isessential to put in appropriate boundary conditions lt

should be noted that the steady-state calculations are

dependent on boundary conditions Often a solution

at one set of boundary conditions is not sufficient to

characterize a thermal system which will operate in a

changing thermal environment (process equipment

operating year-round outdoors for example) In such

cases local weather data based on yearly averages or

yearly extremes of the weather variables should be

used for the calculations

The heat flow through a surface at any point is a function

of several variables which are not directly related

to insulation quality Among others these variables

include ambient temperature movement of the air

roughness and emissivity of the heat flow surface and

the radiation exchange with the surroundings (often

including a great variety of interest) For the calculation

of dew formation variability of the local humidity is animportant factor

Insulation desigh criterion

Apart from a choice of suitable insulation material

for given application it is essential to design proper

insulation thickness It can be determined from two

points of view

Heat loss minimalisation it means reaching the highest

possible economic savings (ideally to calcutate economic

insulation by so- called optimalisation)

Maximum surface temperature (personal protection

against burn) It is usually prescribed by nationallegislation Usual maximum surface temperature is

50 degC if the surrounding air temperature is 25 degC If the

air temperature is different temperature difference

between surface and surrounding air should be up to

25 degC Outdoor piping shall be controlled for maximum

surface temperature every time for summer period

(in the Central Europe calculation air temperature is

30 degC) In boiler rooms surrounding air temperature is

minimally 35 degC

Parameters influencing insulation thick-

ness designHeat flow from the insulation surface is a function of

several parameters which do not relate directly to the

quality of the insulation Here are several parameters

that influence design

thermal conductivity of the insulation material

medium temperature

ambient temperature

external heat transfer coefficient

ECONOMIC THICKNESS

The most substantial return on an investment ininsulation is in energy savings over a period of time

Thermal insulation is one of the most if not the most

significant technology used to conserve energy thereby

reducing pollution Rising energy costs guarantee an

increasing return on any investment made in insulation

In fact it costs less to insulate than not to In the case

of steam process and heat the difference in capital

investment necessary to provide equipment for the

extra steam capacity needed on underinsulated systems

and that investment necessary to insulate plus the

cost of insulation still represents a significant capital

investment savings That insulation saves money is not

the issue here The issue is how much

httpslidepdfcomreaderfullcatalogue-of-technical-insulations-2013-10-598-en 828

Economic thickness calculations are based on the law

of diminishing returns Because no insulation material

can completely stop the flow of heat each increment ofinsulation added to the thickness saves only a percentage

of the heat which has escaped through the underlying

insulation Therefore each increment of insulation

saves less than the one before it and must be evaluated

against the cost of installation to determine if it is a

ldquogood investmentrdquo It is possible to determine how much

insulation applied to a given system will repay its initial

costs in a specified time This point is reached when the

cost of the last incremental of insulation added is offset

by the savings generated by that increment

Refer to the stetch on the left The vertical scale is the

annual cost The horizontal scale is insulation thickness

As the insulation thickness increases from 0 the cost of

heat loss through the insulation decreases Note that this

cost (line B) tends to approach a horizontal line at high

thicknesses As the insulation thickness increases the

cost of the insulation also increases (line A) The total

annual cost at any insulation thickness is the sum of the

cost of the insulation and the cost of the lost heat (line

C) Line C goes through a minimum value of total annual

cost at the Economic thickness

With thicknesses less than the economic thickness the

total annual cost is higher because of the higher valueof the cost of lost heat With thicknesses higher than

the economic thickness the total annual cost is higher

because of the higher value of the cost of the insulation

In the case of computer results each pipe size will be

listed with the recommended thickness as well as

the average heat savings (as compared to a pre-listed

thickness or bare surface whichever chosen) and the

present value of the heat saved

In order to use any of the available manuals tables

or computer programs the two cost factors (cost of

lost energy and cost of insulation) must be found Thefollowing data is generally provided by the investor

Cost of lost energy

This factor is derived from the combination of the

rate of energy transfer the cost of energy and the

operational hours per year of the building Computing

the rate of energy transfer requires surface and

ambient temperatures thermal conductivity of the

chosen insulation the maximumminimum thickness of

insulation to be considered surface emissivity and last

but not least consideration of surface orientation (i evertical horizontal) and wind (air) velocity

Cost of insulation

This factor is derived from computing a bdquounit installed

price of insulationldquo with the total cost annualized overthe projectacutes life The unit installed price is a combination

of the cost of materials cost of labor and worker

productivity This is a sensitive variable in the economic

thickness calculation Only the roughest of regional

averages are available As a result care must be taken not

to perceive these estimates as fixed budget prices used

for installing insulation Material prices are related to the

volume and cost of the insulation jacketing securement

finishing and structural support material used Also

included in this figure are storage and handling costs to

the contractor Labor costs vary regionally and include

wages fringe benefits per diem and travel expensesas well as overhead and profit Labor production varies

with pipe size complexity number of layers necessary

accessibility of piping and surfaces type of materials

used and general working conditions Other costs

involve the job size and increase with the magnitude of

the job They include the preparation scaffolding clean-

up and tear-down costs supervision costs and general

overhead

MAXIMUM SERVICE TEMPERATURE

MST is determined in a laboratory by testing under de-

fined conditions which are dependent upon the form

of delivery and which are laid down in EN 14 706 (for

wired or lamella mats slabs and felts) and EN 14 707(for pipe sections and segments) MST is determined

by establishing the temperature and time related de-

crease in thickness in one-sided heating For the test

the sample shall take a load of 500 Pa The sample is

heated with a transient of at least 5 Kmin The hot-

face temperature must be maintained for 72 hours at

the expected maximum service temperature At the

maximum service temperature no test result must dis-

play a deformation under load of more than 5

In data sheets of different producers (not only mineral

wool) you will often find MST and value which is not

measured accordance to EN 14 706 This temperature

is only assumed When using such temperature there

is a danger of insulation degradation mainly insulation

thickness If mineral wool product has MST 700 or 750 degC

in its data sheet you can be sure that the material will

not withstand such temperature without degradation

of assessed properties Such temperatures shall not

be used Producers should leave field of assumed MST

and test their products to be able to use declared

MST according to EN 14 706 It is an outstandingimprovement compared to the past because individual

products on the European market can be compared to

each other according to standards valid in the EU

Slabs wired and lamella mats Orstech are certificated

according to valid European standards they are

regularly tested in testing laboratory FIW Muumlnchen

according to VDI 2055 and AGI Q 132 Maximum service

temperatures for various products can be found at the

end of the catalogue in the chapter Isover Products on

page 21)

EVAPORATION OF BINDERS

Binders and greasing agents in mineral wool products

dissolve and evaporate in areas with temperatures

higher than 150 degC Binder evaporation does not have any

influence on thermal properties only the compactness

of a material is decreased If proper underconstruction

is made there is almost no danger of insulation slide

down But if too small insulation thickness or improper

type of insulation is used (mostly insulation with too

low density for too high temperatures) danger of binder

evaporation in the whole thickness is possible with

consequent insulation slide down In this case no well

made underconstruction will help Insulation will not

work any more In the outer colder areas no dissolution

and evaporation take place

FIRE PERFORMANCE

FIRE ndash a chemical reaction involving rapid oxidation or

burning of a fuel occurs only when three elements are

present in the proper conditions and proportions

FUEL ndash Fuel can be any combustible material - solid

liquid or gas Most solids and liquids become a vapour

or gas before they burn

OXYGEN ndash The air we breathe is about 21 oxygen Fire

only needs an atmosphere with at least 16 oxygen

HEAT ndash Heat is the energy necessary to increase the

temperature of the fuel to a point where sufficient

vapours are given off for ignition to occur

Fire development depends mostly on room geometry

and ventilation the fuel type the amount and surface

area of the fuel Fire is often discussed in terms of the

temperature development and can be divided into

different stages incipience (ignition) growth flashover

fully developed fire and decay

How materials behave in the early stages of a fire from

ignition to flashover (the spontaneous ignition of hot

smoke and gasses) needs to be assessed at the design

stage for buildings and also for plants and equipment

Euroclasses a new European harmonised classification

system for materialsrsquo reaction to fire in most Europeancountries replaced the old national standards The

Euroclass fire classification covers not only materials

used in building structures but it is being extended also

to technical insulations to cover building equipment

and industrial installations This will help to compare

the reaction to fire of different thermal insulation

materials

The classification levels are A1A2 (completely non-

combustible) B C D E and F A1A2 corresponds to

the safest situation E would be the most dangerous

situation and F would mean not classified

ISOVER mineral wool insulations are totally non-

combustible and completely fire safe achieving

Euroclass A1 fire rating (A2 for products with facing)when classified in accordance with EN 13501-1 One

of the most important issues studied under reaction to

fire performance is the potential for flashover to occur

which can lead to a fire spreading uncontrollably Isover

stone wool is not susceptible to flashover

This is a guide to common building materials and their

likely Euroclassification

Check with individual product manufactures for spedific

product specifications

REACTION TO FIRE

Smoke and flaming droplet risk(1) In the EU classification system for reaction to fire

a construction product will be classified as Euroclass A1

A2 B C D E or F depending on its tendency to burn

(2) The product testing will provide data represented

by the signs s1 s2 or s3 which indicate the tendency

to release smoke Smoke causes over 60 of deaths in

fire across the EU The measurement of smoke release

has been put into these 3 broad bands that can be

translated as ldquolittle or no smokerdquo s1 - rdquoquite a lot of

smokerdquo s2 - rdquosubstantial smoke releaserdquo s3

(3) Some construction products like these made of

polystyrene can melt and ignite to form Flaming

Droplets Wooden products on the other hand will tend

to char before the char falls away as Flaming Particles

to expose more material

These rdquoflaming dropletsparticlesrdquo will tend to

initiate new fires away from the original point of

ignition and must be considered when the products

are used horizontally in ceiling or roof applications

FIRE PROTECTION DESIGN FOR VENTILATION DUCTS

Produced with the stone wool technology of Isover

fire protection system ORSTECH Protect is mineral

wool that combines all the advantages of conventionalthermal and acoustic insulation with top level of fire

safety Mineral wool insulations have the melting point

higher than 1000 degC From the fire protection point of

view products Isover are one of the safest materials

ORSTECH Protect consists of slab or lamella mat

solutions offering up to one hour fire protection for

both vertical and horizontal applications of rectangular

and circular ductwork systems

Passive protection of ventilation ducts is possible by

two basic means

Installed a fire damper into the duct to the place of

fire separation

Use a fire protection insulation system which is

tested according EN 1366-1 and has a classification

protocol in accordance with EN 13 501-3 This second

case is covered by insulation system ORSTECH

Protect

LEGISLATION

Air duct which shall resist the spread of fire from one

compartment to another is tested according to EN

1366-1 The standard can be applied to vertical and

horizontal ducts with or without branches for fire inside

or outside the duct The test measures the time period

for which ducts of specified dimensions suspended as

they would be in practice satisfy criteria when exposed

to fire from inside or outside (separately)

This standard is used in conjunction with EN 1363-1

which prescribes requirements for the determinationof fire resistance of various components of building

structures which are exposed to standard fire

conditions In this standard there are failure criteria

whereby it is possible to evaluate the ability of a tested

duct to prevent fire spread due to the destruction of

the duct (integrity failure E) heat transfer (insulationfailure I) and prevention of the smoke penetration

(smoke leakage S) Fire protection is expressed by time

in minutes for which failure criteria are fulfilled

Designation itself is then done according to

classification standard EN 13 501-3 Classification

states if criteria are fulfilled for fire outside (marking

o rarr i) valid for duct type A or fire inside (marking

irarr o) or from both directions (iharr o) valid for duct type

B and if this is valid for a horizontal duct (marking ho)

or a vertical one (ve) or both (ve ho) Eg class bdquoEI 30 S

ndash ve ho (orarr i) Sldquo represents duct capability to maintain

integrity insulation and smoke leakage for time period

of 30 minutes under fire exposure from outside both

for vertical and horizontal positions

MAXIMUM DUCT SIZES

Maximum size is according to EN 1366-1 for rectangular

duct 1250 x 1000 mm and for circular duct up to

diameter 1000 mm If a duct has bigger dimensions the

classification protocol cannot be used

ACOUSTIC PERFORMANCE

Noise is a sound which impacts negatively on the

surroundings Noise levels emanating from HVAC

services (pipework ductwork and air handlingequipment) and other services can be significantly

reduced with the use of Isover products which will

help to achieve acceptable environmental noise levels

Isover insulations are due to its fibre structure an ideal

material for sound attenuation not only for industrial

application The degree of sound insulation will depend

upon the application the thickness of insulation used

and the nature of any finish used to clad over the

installation In suitable frequencies they can absorb up

to 95 of the sound energy (α = 095)

SOUND ABSORPTIONWhen a sound wave strikes a surface the sound energy

is broken down into transmitted energy (through the

material) converted energy (usually heat) and reflected

energy (back towards the source of the sound)

The more absorbent the material the less sound is

reflected That part of sound energy which is converted

and transmitted is usually expressed as an absorption

coefficient α

The absorption coefficient for a material varies with

the frequency An absorbent layer of mineral wool

has the best absorption capacity in medium and high

frequencies The absorption in low frequencies is

improved by increasing the thickness or by providing an

air gap behind the absorbent layer

Examples of the effectiveness of Isover products in noise

control are given in the following table

ABSORPTIVE STRUCTURES

The most common task in room acoustics is to attenuate

or cancel some frequencies or a whole frequency band

This is possible to realise by using convenient absorptive

material or structures which are frequency-dependent

In this way we can control not only absorption ie

reverberation time but also suppress or completely

remove unpleasant sounds

In a porous material acoustic absorption is mainlycaused by friction in pores ie friction between

oscillating particles and the surface of pores Since the

energy loss due to friction is proportional to the length

of the path the most absorption will occur when the

porous material is placed in a position where the particle

displacement is the largest (maxima displacement)

When sound strikes a rigid wall like concrete for

example a standing wave result and the maxima of

particle displacement appear at the distances λ14

critical distances which must be covered by adsorbers

ie layers with thicknesses d1 = λ

14 d

2 = 3λ

24 d

3 = 5λ

34

In short an absorber with a thickeness d placed directly

on the solid structure will effectively attenuate only

those frequencies where f ge c4d (c is the velocity of

sound 340 ms) For example insulation thickness

of 50 mm wil l reliably attenuate frequencies higher

than 1700 Hz thickness 100 mm then already from

frequencies 850 Hz The higher the frequency the

shorter the wave length and better attenuation

An absorbing layer tightly adjacent to a solid structure

has nevertheless one disadvantage To attenuate

low frequencies it would be necessary to use verythick layers (for example for attenuation of 500 Hz a

thickness of about 20 cm would be necessary) Therefore

acoustic tiles can hardly attenuate low frequency noise

(frequencies lower than 100 dB such as noise from

discotheques)

Fortunately it is possible to avoid expensive acoustic

tiles with high thickness If we use a very thin layer

and place it just in the position of the displacement

maximum of a chosen frequency this chosen frequency

and its odd multiples will be attenuated Acoustic

tiles thus work as a selective frequency filter On theselective basis also other acoustic attenuators work

namely membranes oscillating plates and resonators

ACOUSTICS INSULATIONS

Isover stone wool products with a high longitudinal air-

flow resistance (up to 95 kPasm2) and uniform porosity

(93 ndash 99 ) are used as sound attenuation insulations

In suitable frequencies they can absorb up to 95 of

the sound energy (α = 095) Sound attenuation in a

construction is related to elastic properties of Isover

mineral wool insulations and their low modulus of

elasticity (they have low dynamic toughness and

therefore they are much more suitable for acoustic

purposes in comparison with foam plastics)

Sound attenuation properties of Isover products are

characterised by an absorption coefficient α which

can be found in the table for three thicknesses andsix frequencies According to a given noise spectrum

it is possible to design a sound attenuation structure

of which our material is only a part Since we provide

only insulation material we launch only absorption

coefficients Final attenuation will be dependent on

the whole designed construction (considering also

supporting construction hangers) and assembly

Isover does not design sound attenuation and thus it

is necessary to ask specialists who are able to design a

proper structure

Generally we can say that transmission loss is higher

for constructions with higher plane weight therefore

in most cases insulation with higher density has

better sound attenuation (eg slabs Orstech 65 90

110 Isover FireProtect 150) than insulation with lower

density (eg Orstech 45) Slabs can be manufacturedwith a facing ndash glass black tissue

GENERAL RULES FOR USING ISOVER INSULATIONS

Between insulated piping sufficient distances must

be kept

Valves should be placed without needing to go on theinsulated pipes when handling them

Spindle of valves should not be installed in an upward

direction to avoid water leakage into the insulation

Surfaces before insulating must be clean and dry It

is not possible to insulate wet or frostbitten surfaces

which may later cause damages of insulation or

insulated surfaces

Dirt and rust must be rubbed down from untreated

carbon steels

Smear and oils must be removed by detergents or

solvents from insulated surfaces

Stainless steel surfaces must not be cleaned by

detergents or solvents with chloride content They

may be cleaned only by stainless steel brushes

Chloride solution attacks stainless steel surface and

causes stress corrosion cracking in the material With

increasing surface temperature the danger of stress

corrosion cracking is raised

Piping and equipment from stainless steel can be

insulated only by mineral wool insulation in AS

quality Such material can have maximum content

of chloride ions of 10 mg in 1 kg of the insulation

material

It is necessary to avoid contact of metals which can

cause galvanic corrosion (Cu-Zn Fe-Al)For operating temperatures higher than 600 degC

aluminium jacketing should not be used

Self-tapping screw bold or rivet should be from the

same material as the jacketing

Surfaces with temperatures higher than 500 degC

should be insulated by more insulation layers in a

way that each layer has a different apparent density

Material with higher density insulates better under

higher temperatures than material with lower

density therefore insulation with higher density is

placed closer to the hot side Under low operating

temperatures thermal performance is almost equalSafety working principles must be kept for insulation

assembly

Isover products are packed into PE foil They must be

transported in covered vehicles under such conditions

to avoid moistening or other degradation They must

be stored in covered places

Wired mats

After the cutting of needed length the wired mat shall

be tightly wrapped on the pipe Wired matsrsquo butt jointsshould be in close contact to each other to ensure no

gaps between mats For multiple layer construction

each layer is staggered when applied Each layer must

be secured in place before the next is applied Individual

mats are bound together with a wire with minimal 07

mm thickness Alternatively wired hook or stainless

steel bands (with minimum width of 10 mm) can be

used Maximum distance between hooks is 150 mm

The decision to use multiple layers may be made for one

or more of the following reasons

to provide compensation for pipe expansion andcontraction

to reduce heat flow by staggering joints thus creating

a more thermally efficient installation

to achieve thickness in excess of manufacturersrsquo

capabilities

for retrofitting purposes

Lamella mats

Lamella mats Orstech LSP H consist of mineral wool

lamellas which have been glued to aluminium foil

reinforced with a glass fibre grid and these fibres are

predominantly perpendicular to the surface of themat Compressive strength but thermal conductivity

too are increased compared to mats with a fibre

orientation parallel to the surface (wired mats) Due

to its compressive strength resistance they have less

demands for undeconstruction (less thermal bridges)

in comparison with wired mats Temporary securing in

place is done by aluminium tapes final fixing shall be

done by a baling wire

Protective coverings

The efficiency and service of insulation is directly

dependent upon its protection from moisture entry andmechanical and chemical damage Choices of jacketing

materials are based upon the mechanical chemical

thermal and moisture conditions of the installation

as well as cost and appearance requirements The

basic function of the weather protection is to protect

the insulation from rain snow sleet wind solar

radiation atmospheric contamination and mechanical

damage With this definition in mind several service

requirements must be considered

PIPING INSULATION

For domestic hot water piping with smaller diameters

insulation pipe sections which are covered withaluminium foil are ideal Pipe sections with a facing

have a self-adhesive overlap in a longitudinal joint

to ensure perfect enclosure of a pipe section It is

recommended to secure pipe sections by an aluminium

tape or by galvanized wire transversely They are usually

knotted three times per meter more for pipe sections

with higher diameter Higher diameters should be

secured either by wire or by metal band (at least two

bands per meter)

Pipings with bigger diameters are most commonly

insulated by lamella mats Orstech LSP (stone woolinsulation) or Isover ML-3 (glass wool insulation)

eventually by wired mats Orstech DP (especially for higher

temperatures) Lamella and wired mats are also suitable

for appliances and vessels (both ends and cylindrical

parts) residential heating systems and air ducts

Internal mechanical forces ndash expansion and contraction

of the pipe or vessel must be considered because the

resulting forces are transferred to the external surface ofthe weather barrier Ability to slide elongate or contract

must be provided

External mechanical forces ndash mechanical abuse (ie

tools being dropped abrasion from wind-driven sand

personnel walking on the system) inflicted on a pipe or

vessel needs to be considered in design This may affect

insulation type as well as the weather barrier jacketing

type

Chemical resistance Some industrial environments may

have airborne or spilled corrosive agents that accumulate

on the weather barrier and chemically attack the pipe or

vessel jacketing Elements that create corrosive issues

must be well understood and accounted for Insulation

design of coastal facilities should account for chloride

attack

Galvanic corrosion Contacts between two different

types of metal must be considered for galvanic corrosion

potential Similarly water can act as an electrolyte and

galvanic corrosion can occur because of the differentpotential of the pipe and vessel and a metal jacketing

Materials used as weather barriers for insulation

Typical metal jacketing materials bare aluminium coated

aluminium stainless steel painted steel galvanized steel

aluminium-zinc coated steel

Typical polymeric jacketing materials polyvinyl chloride

(PVC) polyvinyliedene chloride (PVDC) polyisobutylene

multiple-layer composite materials (eg polymericfoil

mesh laminates) fabrics (silicone-impregnated fibreglass)

Fittings valves

Insulation of fittings valves flanges and couplings is

the most time consuming and often expensive aspectof commercial and industrial insulation But it is crucial

to insulate also these parts properly otherwise most of

energy will be transported by these thermal bridges For

example for 200 degC medium heat loss of one uninsulated

valve corresponds to one meter of uninsulated pipe or

ten meters of uninsulated pipe

Fittings are items used to change size direction of flow

level or assembly of piping They may be of the screwed

sweat or welded types Valves are any of various devices

that regulate liquid or gas flow and they may be of the

screwed sweated flanged or welded types Flanges areprotruding rims and edges of the screwed or sweated

type used with fittings valves couplings etc And finally

mechanical couplings are devices used in assembly of

piping Screwed and flanged connections on fittings

valves couplings etc usually require oversized insulation

applications to compensate for the protrusions

Minimum spacing between pipes and

constructions

It is essential to ensure sufficient space between pipies

and between a pipe and a wall (minimally 100 mm)

Otherwise there is a great danger of creating a zone withalmost no cenvenction The result can be too high surface

temperature (needed personal protection against burn)

or possibility of condensation on cold piping Besides

mounting would have been more difficult

DUCTING INSULATION

Isover products are designed to provide high levels of

thermal acoustic and fire protection insulation in HVACductwork applications such as rectangular flat oval and

circular ductwork

The most suitable insulation materials for ducts are

felts KLIMAROL with aluminium foil facing lamella mats

Orstech LSP or Isover ML-3 wired mats Orstech DP or

slabs Orstech H with aluminium foil facing

Duct insulation mounting

Insulation is mostly fixed to the duct by welded pinsWhen using Orstech H slabs with aluminium facing all

the joints shall be sealed with aluminium tape If a steel

clamping band is used it is necessary to use thin-walled

steel L-profiles to avoid trimming of the insulation If

using Orstech slabs without aluminium facing or Orstech

DP wired mats proper jacketing shall be made (the most

suitable is metal steel jacketing)

FIRE PROTECTION OF VENTILATION DUCT

Description

It is vital to develop safe durable and reliable solutions

for ventilation systems as fire can easily spread from the

point of origin via ductwork Isover meets the highest

standards for fire protection providing excellent fire

resistance and top-rated reaction to fire performance

Rectangular ducts shall be insulated by Orstech 65 H

slabs with 40 mm thickness (60 mm for fire resistance EI

60 for a horizontal duct) circular ducts shall be insulated

by Orstech LSP PYRO lamella mats with 50 mm thickness

By these solutions fire resistances EI 15 30 45 and 60 S

have been certified to comply with EN 1366-1

Orstech system with fire resistance has been proven to

meet the requirements of all possible scenarios for fire

from the outside The scenarios can be identified by duct

orientation and duct shape (see table below) Horizontal

ducts normally serve one floor of a building Vertical

ducts normally serve between floors of a building All

scenarios have been done only with one layer Insulation

is fixed to a duct by welded pins Such solution is time

and material saving

Metal ductworkThe steel duct is constructed in sections of galvanised

steel sheet or stainless steel sheet minimum 08 mm thick

(standard duct sheeting for rectangular ducts specified

in DIN 24190 for circular ducts in DIN 24145) Maximum

duct size for which classification protocol is valid is 1250

mm (width) x 1000 mm (height) for rectangular duct or

diameter up to 1000 mm for a circular duct

At each cross joint flanges are fastened to the duct

with spot welds at 150 mm nominal centres

Use a ceramic tape gasket and fire-stopping mastic

between the flanges to seal the joints

Flanges are bolted together with an M10 steel nut

and bolt at each corner

Fasten the flanges together with steel clamps with

bolts M8 (see the figure) in quantity of 3 clamps per 1

meter of the flange length

Drop rods and hangers

Rectangular ducts are suspended by threaded rods and

channel section bearers A duct shall be hung with asuspension system which is independently fire rated

according to EN 1363-1 Certificated suspension system

MUPRO is recommended for the purpose Each steel

hanger consists of two threaded drop rods minimum

M10 and a channel section bearer 3840 mm Fasten

the bearer to the drop rods using hexagonal nuts and

washers The drop rods can be positioned either inside

the insulation material or outside If drop rods are outside

there is no need to insulate them separately The bearers

are positioned inside the insulation material

Circular ducts are suspended by MUumlPRO steel hangerswhich consist of two threaded drop rods minimum

M10 and a two-part industrial circular band The ends

of each band section are bent outwards Fasten the band

sections together and attach them to the drop rods with

hexagonal nuts and washers Place these hangers inside

the insulation The rods do not need to be protected by

insulation

When fixing them to a concrete construction use all-

steel expanding anchors to fasten the threaded rod

hangers to concrete soffits The anchors should penetrate

the concrete by at least 60 mm When fixing to a steel

supporting construction drill a hole through the steel

member allowing the drop rod to be supported by a steel

nut and washer above If a clamp type fixing is used the

clamp must be steel suitable for the purpose It should

pass around the steel member and be fastened back on

itself Clamps that rely on friction to hold them in place

are not suitable

Insulation

Rectangular ducts are insulated by Orstech 65 H slabs

(with apparent density 65 kgm3 and with one-sidedaluminium foil facing) with 40 mm thickness (60 mm

for fire resistance EI 60 for a horizontal duct) Circular

ducts are insulated by lamella mats Orstech LSP PYRO

with 50 mm thickness Insulation slabs (lamella mats)

need to be cut to fit the duct as tightly as possible the

insulation may need to be cut to fit around flanged duct

joints Install the insulation so that one slab (lamella

mat) is adjacent and tightly fitted against the other No

gaps must be present between butt joints of insulation

Insulation can be easily cut with a standard laggers knife

There is no need for adhesive on joints All the joints shall

be sealed by aluminium tape For rectangular ducts in theposition of flange the slabs are snick first 15 mm of the

thickness to avoid lifting of the slabs Butt joints should

be positioned out of flanges Fire protective insulation for

circular ducts does not require usage of a wire net mesh

on the outer side of insulation

Stud welded pins

The insulation is fixed to the duct using steel pins 27 mm

to 3 mm nominal diameter and spring steel washers

minimum 30 mm diameter The length of pin should

be equal to the insulation thickness The orientational

number of pins is 16 piecesm2 for rectangular ducts and14 piecesm2 for circular ducts

Recommended distance from duct edges and joints is

80 mm 50 mm from flanges

Wallfloor penetration

At wallfloor penetration one must insure the same fire

resistance of ventilation duct as has the fire separation

to avoid the spreading of fire from one compartment to

other via a duct This is possible by two basic principles

or their combinations - install a fire damper at the

penetration point or use insulation with fire resistancewhere the crucial thing is the fire-stopping The fire-

stopping is from the second insulation layer with the

width of 150 mm from both side of fire separation

The same general principle is used for both rectangular

and circular ducts regardless of orientation Place

the duct in the penetration of the construction with

approximately 10 mm gap between insulated duct and

opening Before installing the fire-stopping with the

same insulation thickness as is used for the first layer

pack the space between the duct and partition with

as many pieces of insulation as possible Ensure tight

compression in order to completely fill the opening This

must be done because system ORSTECH Protect does

not require stiffeners inside the duct Then install thesecond insulation layer so that it is adjacent and tightly

fitted against the penetration The insulation must be

cut leaving excess length so that it exerts some pressure

between the penetration and the last fitted piece of

insulation

The second layer is fixed by welded pins with length

equal to double insulation thickness The second layer for

circular ducts (lamella mats) is clamped with 1-2 wires

with a diameter 16 mm Then the insulation is secured

to the duct by welded pins

A inovative solution is the considerable simplification of

a fire-stopping concept There is no need to use any kind

of stiffener either inside or outside of the duct A great

advantage is to mount the whole ventilation section

at once and the wall itself can be placed anywhere

Therefore the position variability of fire separation is

provided No glue or mastic is needed at wallfloor

penetrations

Fire classification

ORSTECH Protect insulation with fire resistance has

been tested by the fire testing laboratory Pavus as an

authorised body AO 216 Classification protocols on the

request

Fire protection system ORSTECH Protect has been tested

in accordance with EN 1366-1 Maximum size for the

rectangular duct is 1250 x 1000 mm and for the circular

duct up to diameter 1000 mm If a duct has bigger

dimensions the certificate connected to the standard

cannot be used

capabilities

for retrofitting purposes

Insulation is usually fixed by mechanical fasteners - by

studs or pins Spacing between them is dependent on the

design of the vessel its surface temperature fire hazard

potential involved and presumptive loading Each slab

should be fixed by minimally two pins

BOILER INSULATIONInsulations for boilers kettles and ovens are one of

the most demanding applications in industry because

these units are operating at very high temperatures

Good insulation not only saves energy considerably but

the main purpose is personal protection against burn

According to the surface shape and temperature are used

either slabs with higher densities Orstech 65 to 110 (for

boilers with flat surfaces) or wired mats Orstech DP 65 to

DP 100 (for boilers with cylindrical parts)

Boiler walls are exposed to very high temperatures

(usually around 500 or 600 degC) Therefore it is essential

to use mechanical fasteners for the fixing of insulation

to the surface Insulation for boilers is done in at least

two layers each layer must be staggered when applied

Each layer must be secured in place before the next is

applied A product with high density should be placed as

the first layer because it has a higher maximum surface

temperature (higher resistance against high operating

temperatures) and better insulation performace than

products with lower densities

CHIMNEY INSULATION

Insulations for prefabricated chimneys are directly

supplied by producers of such systems In cooperation

with specialized wholesale companies we offer slabs

with multi-plate stripes which allow easy and perfect

application for prefabricated chimneys suitable both

for stainless steel chimney liners as well as with other

brands of chimney lining systems The main advantage

is the time saving during the installation in comparison

with the use of lamella mats and horizontal orientation

of fibres (better thermal conductivity) Insulation

dimensions ie thickness of slabs and groove dimensions

dependent on the chimney diameter are supplied

according to customer needs

For non-prefabricated chimneys are mostly used wired

mats Orstech DP or slabs Orstech 90 or 110 (for chimneys

with rectangular cross-section)

TECHNOLOGICAL APPLIANCEINSULATIONWhere big quantities of energy is used eg within

petrochemical paper and pulp industries thermal

insulation is necessary in order to reduce expensive

energy losses Tanks vessels exhausts exchangers

and technological piping are appliances that are often

working at high temperatures Good insulation will save

energy considerably which will benefit the environment

and keep the working costs down At the same time

the insulation will reduce temperature fall which could

disturb the production process

Proper insulation can be chosen in accordance with

dimension surface temperature the manner of fixing

and requirements for jacketing For pipes and cylindrical

parts are used lamella mats Orstech LSP H and Isover

ML-3 (only for temperatures up to 250 degC) or wired mats

Orstech DP For appliances and vessels with rectangular

shapes Orstech slabs are suitable (type according to a

surface temperature) Slabs can have aluminium facing

If insulation is done in more than one layer each layer

is staggered when applied Each layer must be secured

in place before the next is applied The decision to use

multiple layers may be made for one or more of the

following reasons

BASIC FUNCTIONS OF TECHNICAL INSULATIONS

Insulations are defined as those materials which retard

the flow of heat energy by performing one or more of

the following functions

Energy conservation minimizing unwanted heat loss

gain from building HVAC systems as well as preserv-

ing natural and financial resources

Personnel protection controlling surface tempera-tures to avoid contact burns (hot or cold) ndash maximum

surface temperature criterion

Condensation control minimizing condensation by

keeping the surface temperature above the dew point

of surrounding air

Prevent internal condensation in pipes

Process control minimizing temperature change in

process fluids where close control is needed

Increase operating efficiency of heating ventilating

cooling plumbing steam process and power systems

found in commercial and industrial installations

Freeze protection minimizing energy required for

heat tracing systems andor extending the time to

freeze in the event of system failure Freeze protec-

tion of vessels and tanks with various accumulated

fluids or fuels

Noise control reducingcontrolling noise in mechani-

cal systems

Fire safety protecting critical building elements and

slowing the spread of fire in buildings

The application of thermal insulation on pipe vessels

and ducts is recognized as a necessary requirement in

any construction activity The thickness and extent of

insulation required has always been subject to arbi-

trary and imprecise decisions with little engineering or

economic input No material incorporated in a modern

construction project provides the owner with as good

a financial return throughout the life of the facility as

does insulation

The investment in insulation may protect the equip-

ment and personnel present during the life of the facil-

ity Proper insulation prevents condensation chemical

corrosion and excessive heat in fire hazard areas Added

human comfort provided by proper insulation in hotelsoffice buildings schools or factories adds considerably

to the value of the facility and productivity of its per-

sonnel Process temperatures in heat traced piping are

more efficiently maintained with proper insulation The

size of the heat generating equipment can be reduced

when designed with an efficient insulation system In

some cases insulation is essential to an industrylsquos very

existence as with the power the process and

the cold storage

However the most substantial return on an investment

in insulation is in energy savings over a period of timeThese savings are becoming more and more empha-

sized in the industrial insulation field as energy costs

rise coupled with the fact that industrial plants and

utilities usually account for about half of the total en-

ergy consumption

Recently the environmental impact of new renovated

or relocated industrial and commercial facilities has

taken on new importance Thermal insulation is one of

the most if not the most significant technology used

to conserve energy thereby reducing pollution Besides

minimizing heat loss insulation increases process ef-

ficiency helps maintain employee safety comfort and

production

For their thermal protection of various industrial appli-

cations it is a necessity to design and use such insula-

tion material that meet operating conditions Isover will

help you find the most suitable insulation product for

given application

HEAT FLOW TRANSMISSION

Heat transfer is carried out by three heat transmission

modes conduction convection and radiation

Conduction

Heat transfers from warmer surface to colder through

solid material or gas (by fibres in mineral wool

insulations) The more insulant the material the less

the conduction

Convection

Transfer of heat caused by air movements (because of

temperature and density gradient) Hot air moves up

and heat dissipates The quieter the air the less the

convection Convection can be natural (when calculating

insulation inside the building) or forced (for calculation

outside where wind blows)

Radiation

Each material absorbs or emits thermal radiations

depending on its temperature and its emissivity Unlike

conduction or convection heat can be transferred by

radiation also in a vacuum When radiation is absorbed

or reflected there is less thermal transfer Measure of

radiating capacity of a material is emissivity ε Absolute

black body has the highest emissivity (ε = 1) Rough

and dark surfaces approaches such value (for example

mineral wool insulation without jacketing ε = 094)

contrary to bright and smooth surfaces that have very

low emissivity (for example polished aluminium foil ε

= 005) For design it is necessary to take into account

that covering of the bright surface with dust will

increase emissivity significantly

These three transport mechanisms are applied in

two very important quantities ndash surface heat transfer

coefficient α and thermal transmittance U

Thermal insulations impede conduction convection and

radiative effects

by creating a thermal barrier against conductionby suppressing air movements

by limiting radiative effects

Surface heat transfer coefficient

Two heat transmissions (convection and radiation)

influence the heat transfer coefficient α [W(m2middotK)] The

higher the heat transfer coefficient the higher the heat

flow rate from a warm surface

Thermal transmittance

Thermal transmittance (also called Overall heat transfer

coefficient) U (for flat surfaces [W(m2middotK)] for pipes [W

(mmiddotK)]) is inverted value of thermal resistance and it

takes into account the influence of all heat transmission

modes (conduction convection and radiation)

INSULATION SYSTEM DESIGN

GENERAL

An insulation system is the combination of insulations

finishes and application methods which are used toachieve specific design objectives Among these are

Energy savings

Reduced operating costs

Condensation control

Chemical compatibility with the metals being

insulated the atmosphere to which the system

will be exposed and the various components of the

insulation system itself

Protection of mechanical and insulation systems

from mechanical abuse and atmospheric damage

Personnel protection

Fire protection

Sound control

Future requirements for access to piping fittings etc

Accommodation to limited clearances or work space

While there are several choices of insulation materials

which meet basic thermal and cost-effective

requirements of an installation choices become more

limited with each additional design objective that

comes into play

INSULATION THICKNESS CALCULATION

When calculating the thickness of the insulation it isessential to put in appropriate boundary conditions lt

should be noted that the steady-state calculations are

dependent on boundary conditions Often a solution

at one set of boundary conditions is not sufficient to

characterize a thermal system which will operate in a

changing thermal environment (process equipment

operating year-round outdoors for example) In such

cases local weather data based on yearly averages or

yearly extremes of the weather variables should be

used for the calculations

The heat flow through a surface at any point is a function

of several variables which are not directly related

to insulation quality Among others these variables

include ambient temperature movement of the air

roughness and emissivity of the heat flow surface and

the radiation exchange with the surroundings (often

including a great variety of interest) For the calculation

of dew formation variability of the local humidity is animportant factor

Insulation desigh criterion

Apart from a choice of suitable insulation material

for given application it is essential to design proper

insulation thickness It can be determined from two

points of view

Heat loss minimalisation it means reaching the highest

possible economic savings (ideally to calcutate economic

insulation by so- called optimalisation)

Maximum surface temperature (personal protection

against burn) It is usually prescribed by nationallegislation Usual maximum surface temperature is

50 degC if the surrounding air temperature is 25 degC If the

air temperature is different temperature difference

between surface and surrounding air should be up to

25 degC Outdoor piping shall be controlled for maximum

surface temperature every time for summer period

(in the Central Europe calculation air temperature is

30 degC) In boiler rooms surrounding air temperature is

minimally 35 degC

Parameters influencing insulation thick-

ness designHeat flow from the insulation surface is a function of

several parameters which do not relate directly to the

quality of the insulation Here are several parameters

that influence design

thermal conductivity of the insulation material

medium temperature

ambient temperature

external heat transfer coefficient

ECONOMIC THICKNESS

The most substantial return on an investment ininsulation is in energy savings over a period of time

Thermal insulation is one of the most if not the most

significant technology used to conserve energy thereby

reducing pollution Rising energy costs guarantee an

increasing return on any investment made in insulation

In fact it costs less to insulate than not to In the case

of steam process and heat the difference in capital

investment necessary to provide equipment for the

extra steam capacity needed on underinsulated systems

and that investment necessary to insulate plus the

cost of insulation still represents a significant capital

investment savings That insulation saves money is not

the issue here The issue is how much

httpslidepdfcomreaderfullcatalogue-of-technical-insulations-2013-10-598-en 828

Economic thickness calculations are based on the law

of diminishing returns Because no insulation material

can completely stop the flow of heat each increment ofinsulation added to the thickness saves only a percentage

of the heat which has escaped through the underlying

insulation Therefore each increment of insulation

saves less than the one before it and must be evaluated

against the cost of installation to determine if it is a

ldquogood investmentrdquo It is possible to determine how much

insulation applied to a given system will repay its initial

costs in a specified time This point is reached when the

cost of the last incremental of insulation added is offset

by the savings generated by that increment

Refer to the stetch on the left The vertical scale is the

annual cost The horizontal scale is insulation thickness

As the insulation thickness increases from 0 the cost of

heat loss through the insulation decreases Note that this

cost (line B) tends to approach a horizontal line at high

thicknesses As the insulation thickness increases the

cost of the insulation also increases (line A) The total

annual cost at any insulation thickness is the sum of the

cost of the insulation and the cost of the lost heat (line

C) Line C goes through a minimum value of total annual

cost at the Economic thickness

With thicknesses less than the economic thickness the

total annual cost is higher because of the higher valueof the cost of lost heat With thicknesses higher than

the economic thickness the total annual cost is higher

because of the higher value of the cost of the insulation

In the case of computer results each pipe size will be

listed with the recommended thickness as well as

the average heat savings (as compared to a pre-listed

thickness or bare surface whichever chosen) and the

present value of the heat saved

In order to use any of the available manuals tables

or computer programs the two cost factors (cost of

lost energy and cost of insulation) must be found Thefollowing data is generally provided by the investor

Cost of lost energy

This factor is derived from the combination of the

rate of energy transfer the cost of energy and the

operational hours per year of the building Computing

the rate of energy transfer requires surface and

ambient temperatures thermal conductivity of the

chosen insulation the maximumminimum thickness of

insulation to be considered surface emissivity and last

but not least consideration of surface orientation (i evertical horizontal) and wind (air) velocity

Cost of insulation

This factor is derived from computing a bdquounit installed

price of insulationldquo with the total cost annualized overthe projectacutes life The unit installed price is a combination

of the cost of materials cost of labor and worker

productivity This is a sensitive variable in the economic

thickness calculation Only the roughest of regional

averages are available As a result care must be taken not

to perceive these estimates as fixed budget prices used

for installing insulation Material prices are related to the

volume and cost of the insulation jacketing securement

finishing and structural support material used Also

included in this figure are storage and handling costs to

the contractor Labor costs vary regionally and include

wages fringe benefits per diem and travel expensesas well as overhead and profit Labor production varies

with pipe size complexity number of layers necessary

accessibility of piping and surfaces type of materials

used and general working conditions Other costs

involve the job size and increase with the magnitude of

the job They include the preparation scaffolding clean-

up and tear-down costs supervision costs and general

overhead

MAXIMUM SERVICE TEMPERATURE

MST is determined in a laboratory by testing under de-

fined conditions which are dependent upon the form

of delivery and which are laid down in EN 14 706 (for

wired or lamella mats slabs and felts) and EN 14 707(for pipe sections and segments) MST is determined

by establishing the temperature and time related de-

crease in thickness in one-sided heating For the test

the sample shall take a load of 500 Pa The sample is

heated with a transient of at least 5 Kmin The hot-

face temperature must be maintained for 72 hours at

the expected maximum service temperature At the

maximum service temperature no test result must dis-

play a deformation under load of more than 5

In data sheets of different producers (not only mineral

wool) you will often find MST and value which is not

measured accordance to EN 14 706 This temperature

is only assumed When using such temperature there

is a danger of insulation degradation mainly insulation

thickness If mineral wool product has MST 700 or 750 degC

in its data sheet you can be sure that the material will

not withstand such temperature without degradation

of assessed properties Such temperatures shall not

be used Producers should leave field of assumed MST

and test their products to be able to use declared

MST according to EN 14 706 It is an outstandingimprovement compared to the past because individual

products on the European market can be compared to

each other according to standards valid in the EU

Slabs wired and lamella mats Orstech are certificated

according to valid European standards they are

regularly tested in testing laboratory FIW Muumlnchen

according to VDI 2055 and AGI Q 132 Maximum service

temperatures for various products can be found at the

end of the catalogue in the chapter Isover Products on

page 21)

EVAPORATION OF BINDERS

Binders and greasing agents in mineral wool products

dissolve and evaporate in areas with temperatures

higher than 150 degC Binder evaporation does not have any

influence on thermal properties only the compactness

of a material is decreased If proper underconstruction

is made there is almost no danger of insulation slide

down But if too small insulation thickness or improper

type of insulation is used (mostly insulation with too

low density for too high temperatures) danger of binder

evaporation in the whole thickness is possible with

consequent insulation slide down In this case no well

made underconstruction will help Insulation will not

work any more In the outer colder areas no dissolution

and evaporation take place

FIRE PERFORMANCE

FIRE ndash a chemical reaction involving rapid oxidation or

burning of a fuel occurs only when three elements are

present in the proper conditions and proportions

FUEL ndash Fuel can be any combustible material - solid

liquid or gas Most solids and liquids become a vapour

or gas before they burn

OXYGEN ndash The air we breathe is about 21 oxygen Fire

only needs an atmosphere with at least 16 oxygen

HEAT ndash Heat is the energy necessary to increase the

temperature of the fuel to a point where sufficient

vapours are given off for ignition to occur

Fire development depends mostly on room geometry

and ventilation the fuel type the amount and surface

area of the fuel Fire is often discussed in terms of the

temperature development and can be divided into

different stages incipience (ignition) growth flashover

fully developed fire and decay

How materials behave in the early stages of a fire from

ignition to flashover (the spontaneous ignition of hot

smoke and gasses) needs to be assessed at the design

stage for buildings and also for plants and equipment

Euroclasses a new European harmonised classification

system for materialsrsquo reaction to fire in most Europeancountries replaced the old national standards The

Euroclass fire classification covers not only materials

used in building structures but it is being extended also

to technical insulations to cover building equipment

and industrial installations This will help to compare

the reaction to fire of different thermal insulation

materials

The classification levels are A1A2 (completely non-

combustible) B C D E and F A1A2 corresponds to

the safest situation E would be the most dangerous

situation and F would mean not classified

ISOVER mineral wool insulations are totally non-

combustible and completely fire safe achieving

Euroclass A1 fire rating (A2 for products with facing)when classified in accordance with EN 13501-1 One

of the most important issues studied under reaction to

fire performance is the potential for flashover to occur

which can lead to a fire spreading uncontrollably Isover

stone wool is not susceptible to flashover

This is a guide to common building materials and their

likely Euroclassification

Check with individual product manufactures for spedific

product specifications

REACTION TO FIRE

Smoke and flaming droplet risk(1) In the EU classification system for reaction to fire

a construction product will be classified as Euroclass A1

A2 B C D E or F depending on its tendency to burn

(2) The product testing will provide data represented

by the signs s1 s2 or s3 which indicate the tendency

to release smoke Smoke causes over 60 of deaths in

fire across the EU The measurement of smoke release

has been put into these 3 broad bands that can be

translated as ldquolittle or no smokerdquo s1 - rdquoquite a lot of

smokerdquo s2 - rdquosubstantial smoke releaserdquo s3

(3) Some construction products like these made of

polystyrene can melt and ignite to form Flaming

Droplets Wooden products on the other hand will tend

to char before the char falls away as Flaming Particles

to expose more material

These rdquoflaming dropletsparticlesrdquo will tend to

initiate new fires away from the original point of

ignition and must be considered when the products

are used horizontally in ceiling or roof applications

FIRE PROTECTION DESIGN FOR VENTILATION DUCTS

Produced with the stone wool technology of Isover

fire protection system ORSTECH Protect is mineral

wool that combines all the advantages of conventionalthermal and acoustic insulation with top level of fire

safety Mineral wool insulations have the melting point

higher than 1000 degC From the fire protection point of

view products Isover are one of the safest materials

ORSTECH Protect consists of slab or lamella mat

solutions offering up to one hour fire protection for

both vertical and horizontal applications of rectangular

and circular ductwork systems

Passive protection of ventilation ducts is possible by

two basic means

Installed a fire damper into the duct to the place of

fire separation

Use a fire protection insulation system which is

tested according EN 1366-1 and has a classification

protocol in accordance with EN 13 501-3 This second

case is covered by insulation system ORSTECH

Protect

LEGISLATION

Air duct which shall resist the spread of fire from one

compartment to another is tested according to EN

1366-1 The standard can be applied to vertical and

horizontal ducts with or without branches for fire inside

or outside the duct The test measures the time period

for which ducts of specified dimensions suspended as

they would be in practice satisfy criteria when exposed

to fire from inside or outside (separately)

This standard is used in conjunction with EN 1363-1

which prescribes requirements for the determinationof fire resistance of various components of building

structures which are exposed to standard fire

conditions In this standard there are failure criteria

whereby it is possible to evaluate the ability of a tested

duct to prevent fire spread due to the destruction of

the duct (integrity failure E) heat transfer (insulationfailure I) and prevention of the smoke penetration

(smoke leakage S) Fire protection is expressed by time

in minutes for which failure criteria are fulfilled

Designation itself is then done according to

classification standard EN 13 501-3 Classification

states if criteria are fulfilled for fire outside (marking

o rarr i) valid for duct type A or fire inside (marking

irarr o) or from both directions (iharr o) valid for duct type

B and if this is valid for a horizontal duct (marking ho)

or a vertical one (ve) or both (ve ho) Eg class bdquoEI 30 S

ndash ve ho (orarr i) Sldquo represents duct capability to maintain

integrity insulation and smoke leakage for time period

of 30 minutes under fire exposure from outside both

for vertical and horizontal positions

MAXIMUM DUCT SIZES

Maximum size is according to EN 1366-1 for rectangular

duct 1250 x 1000 mm and for circular duct up to

diameter 1000 mm If a duct has bigger dimensions the

classification protocol cannot be used

ACOUSTIC PERFORMANCE

Noise is a sound which impacts negatively on the

surroundings Noise levels emanating from HVAC

services (pipework ductwork and air handlingequipment) and other services can be significantly

reduced with the use of Isover products which will

help to achieve acceptable environmental noise levels

Isover insulations are due to its fibre structure an ideal

material for sound attenuation not only for industrial

application The degree of sound insulation will depend

upon the application the thickness of insulation used

and the nature of any finish used to clad over the

installation In suitable frequencies they can absorb up

to 95 of the sound energy (α = 095)

SOUND ABSORPTIONWhen a sound wave strikes a surface the sound energy

is broken down into transmitted energy (through the

material) converted energy (usually heat) and reflected

energy (back towards the source of the sound)

The more absorbent the material the less sound is

reflected That part of sound energy which is converted

and transmitted is usually expressed as an absorption

coefficient α

The absorption coefficient for a material varies with

the frequency An absorbent layer of mineral wool

has the best absorption capacity in medium and high

frequencies The absorption in low frequencies is

improved by increasing the thickness or by providing an

air gap behind the absorbent layer

Examples of the effectiveness of Isover products in noise

control are given in the following table

ABSORPTIVE STRUCTURES

The most common task in room acoustics is to attenuate

or cancel some frequencies or a whole frequency band

This is possible to realise by using convenient absorptive

material or structures which are frequency-dependent

In this way we can control not only absorption ie

reverberation time but also suppress or completely

remove unpleasant sounds

In a porous material acoustic absorption is mainlycaused by friction in pores ie friction between

oscillating particles and the surface of pores Since the

energy loss due to friction is proportional to the length

of the path the most absorption will occur when the

porous material is placed in a position where the particle

displacement is the largest (maxima displacement)

When sound strikes a rigid wall like concrete for

example a standing wave result and the maxima of

particle displacement appear at the distances λ14

critical distances which must be covered by adsorbers

ie layers with thicknesses d1 = λ

14 d

2 = 3λ

24 d

3 = 5λ

34

In short an absorber with a thickeness d placed directly

on the solid structure will effectively attenuate only

those frequencies where f ge c4d (c is the velocity of

sound 340 ms) For example insulation thickness

of 50 mm wil l reliably attenuate frequencies higher

than 1700 Hz thickness 100 mm then already from

frequencies 850 Hz The higher the frequency the

shorter the wave length and better attenuation

An absorbing layer tightly adjacent to a solid structure

has nevertheless one disadvantage To attenuate

low frequencies it would be necessary to use verythick layers (for example for attenuation of 500 Hz a

thickness of about 20 cm would be necessary) Therefore

acoustic tiles can hardly attenuate low frequency noise

(frequencies lower than 100 dB such as noise from

discotheques)

Fortunately it is possible to avoid expensive acoustic

tiles with high thickness If we use a very thin layer

and place it just in the position of the displacement

maximum of a chosen frequency this chosen frequency

and its odd multiples will be attenuated Acoustic

tiles thus work as a selective frequency filter On theselective basis also other acoustic attenuators work

namely membranes oscillating plates and resonators

ACOUSTICS INSULATIONS

Isover stone wool products with a high longitudinal air-

flow resistance (up to 95 kPasm2) and uniform porosity

(93 ndash 99 ) are used as sound attenuation insulations

In suitable frequencies they can absorb up to 95 of

the sound energy (α = 095) Sound attenuation in a

construction is related to elastic properties of Isover

mineral wool insulations and their low modulus of

elasticity (they have low dynamic toughness and

therefore they are much more suitable for acoustic

purposes in comparison with foam plastics)

Sound attenuation properties of Isover products are

characterised by an absorption coefficient α which

can be found in the table for three thicknesses andsix frequencies According to a given noise spectrum

it is possible to design a sound attenuation structure

of which our material is only a part Since we provide

only insulation material we launch only absorption

coefficients Final attenuation will be dependent on

the whole designed construction (considering also

supporting construction hangers) and assembly

Isover does not design sound attenuation and thus it

is necessary to ask specialists who are able to design a

proper structure

Generally we can say that transmission loss is higher

for constructions with higher plane weight therefore

in most cases insulation with higher density has

better sound attenuation (eg slabs Orstech 65 90

110 Isover FireProtect 150) than insulation with lower

density (eg Orstech 45) Slabs can be manufacturedwith a facing ndash glass black tissue

GENERAL RULES FOR USING ISOVER INSULATIONS

Between insulated piping sufficient distances must

be kept

Valves should be placed without needing to go on theinsulated pipes when handling them

Spindle of valves should not be installed in an upward

direction to avoid water leakage into the insulation

Surfaces before insulating must be clean and dry It

is not possible to insulate wet or frostbitten surfaces

which may later cause damages of insulation or

insulated surfaces

Dirt and rust must be rubbed down from untreated

carbon steels

Smear and oils must be removed by detergents or

solvents from insulated surfaces

Stainless steel surfaces must not be cleaned by

detergents or solvents with chloride content They

may be cleaned only by stainless steel brushes

Chloride solution attacks stainless steel surface and

causes stress corrosion cracking in the material With

increasing surface temperature the danger of stress

corrosion cracking is raised

Piping and equipment from stainless steel can be

insulated only by mineral wool insulation in AS

quality Such material can have maximum content

of chloride ions of 10 mg in 1 kg of the insulation

material

It is necessary to avoid contact of metals which can

cause galvanic corrosion (Cu-Zn Fe-Al)For operating temperatures higher than 600 degC

aluminium jacketing should not be used

Self-tapping screw bold or rivet should be from the

same material as the jacketing

Surfaces with temperatures higher than 500 degC

should be insulated by more insulation layers in a

way that each layer has a different apparent density

Material with higher density insulates better under

higher temperatures than material with lower

density therefore insulation with higher density is

placed closer to the hot side Under low operating

temperatures thermal performance is almost equalSafety working principles must be kept for insulation

assembly

Isover products are packed into PE foil They must be

transported in covered vehicles under such conditions

to avoid moistening or other degradation They must

be stored in covered places

Wired mats

After the cutting of needed length the wired mat shall

be tightly wrapped on the pipe Wired matsrsquo butt jointsshould be in close contact to each other to ensure no

gaps between mats For multiple layer construction

each layer is staggered when applied Each layer must

be secured in place before the next is applied Individual

mats are bound together with a wire with minimal 07

mm thickness Alternatively wired hook or stainless

steel bands (with minimum width of 10 mm) can be

used Maximum distance between hooks is 150 mm

The decision to use multiple layers may be made for one

or more of the following reasons

to provide compensation for pipe expansion andcontraction

to reduce heat flow by staggering joints thus creating

a more thermally efficient installation

to achieve thickness in excess of manufacturersrsquo

capabilities

for retrofitting purposes

Lamella mats

Lamella mats Orstech LSP H consist of mineral wool

lamellas which have been glued to aluminium foil

reinforced with a glass fibre grid and these fibres are

predominantly perpendicular to the surface of themat Compressive strength but thermal conductivity

too are increased compared to mats with a fibre

orientation parallel to the surface (wired mats) Due

to its compressive strength resistance they have less

demands for undeconstruction (less thermal bridges)

in comparison with wired mats Temporary securing in

place is done by aluminium tapes final fixing shall be

done by a baling wire

Protective coverings

The efficiency and service of insulation is directly

dependent upon its protection from moisture entry andmechanical and chemical damage Choices of jacketing

materials are based upon the mechanical chemical

thermal and moisture conditions of the installation

as well as cost and appearance requirements The

basic function of the weather protection is to protect

the insulation from rain snow sleet wind solar

radiation atmospheric contamination and mechanical

damage With this definition in mind several service

requirements must be considered

PIPING INSULATION

For domestic hot water piping with smaller diameters

insulation pipe sections which are covered withaluminium foil are ideal Pipe sections with a facing

have a self-adhesive overlap in a longitudinal joint

to ensure perfect enclosure of a pipe section It is

recommended to secure pipe sections by an aluminium

tape or by galvanized wire transversely They are usually

knotted three times per meter more for pipe sections

with higher diameter Higher diameters should be

secured either by wire or by metal band (at least two

bands per meter)

Pipings with bigger diameters are most commonly

insulated by lamella mats Orstech LSP (stone woolinsulation) or Isover ML-3 (glass wool insulation)

eventually by wired mats Orstech DP (especially for higher

temperatures) Lamella and wired mats are also suitable

for appliances and vessels (both ends and cylindrical

parts) residential heating systems and air ducts

Internal mechanical forces ndash expansion and contraction

of the pipe or vessel must be considered because the

resulting forces are transferred to the external surface ofthe weather barrier Ability to slide elongate or contract

must be provided

External mechanical forces ndash mechanical abuse (ie

tools being dropped abrasion from wind-driven sand

personnel walking on the system) inflicted on a pipe or

vessel needs to be considered in design This may affect

insulation type as well as the weather barrier jacketing

type

Chemical resistance Some industrial environments may

have airborne or spilled corrosive agents that accumulate

on the weather barrier and chemically attack the pipe or

vessel jacketing Elements that create corrosive issues

must be well understood and accounted for Insulation

design of coastal facilities should account for chloride

attack

Galvanic corrosion Contacts between two different

types of metal must be considered for galvanic corrosion

potential Similarly water can act as an electrolyte and

galvanic corrosion can occur because of the differentpotential of the pipe and vessel and a metal jacketing

Materials used as weather barriers for insulation

Typical metal jacketing materials bare aluminium coated

aluminium stainless steel painted steel galvanized steel

aluminium-zinc coated steel

Typical polymeric jacketing materials polyvinyl chloride

(PVC) polyvinyliedene chloride (PVDC) polyisobutylene

multiple-layer composite materials (eg polymericfoil

mesh laminates) fabrics (silicone-impregnated fibreglass)

Fittings valves

Insulation of fittings valves flanges and couplings is

the most time consuming and often expensive aspectof commercial and industrial insulation But it is crucial

to insulate also these parts properly otherwise most of

energy will be transported by these thermal bridges For

example for 200 degC medium heat loss of one uninsulated

valve corresponds to one meter of uninsulated pipe or

ten meters of uninsulated pipe

Fittings are items used to change size direction of flow

level or assembly of piping They may be of the screwed

sweat or welded types Valves are any of various devices

that regulate liquid or gas flow and they may be of the

screwed sweated flanged or welded types Flanges areprotruding rims and edges of the screwed or sweated

type used with fittings valves couplings etc And finally

mechanical couplings are devices used in assembly of

piping Screwed and flanged connections on fittings

valves couplings etc usually require oversized insulation

applications to compensate for the protrusions

Minimum spacing between pipes and

constructions

It is essential to ensure sufficient space between pipies

and between a pipe and a wall (minimally 100 mm)

Otherwise there is a great danger of creating a zone withalmost no cenvenction The result can be too high surface

temperature (needed personal protection against burn)

or possibility of condensation on cold piping Besides

mounting would have been more difficult

DUCTING INSULATION

Isover products are designed to provide high levels of

thermal acoustic and fire protection insulation in HVACductwork applications such as rectangular flat oval and

circular ductwork

The most suitable insulation materials for ducts are

felts KLIMAROL with aluminium foil facing lamella mats

Orstech LSP or Isover ML-3 wired mats Orstech DP or

slabs Orstech H with aluminium foil facing

Duct insulation mounting

Insulation is mostly fixed to the duct by welded pinsWhen using Orstech H slabs with aluminium facing all

the joints shall be sealed with aluminium tape If a steel

clamping band is used it is necessary to use thin-walled

steel L-profiles to avoid trimming of the insulation If

using Orstech slabs without aluminium facing or Orstech

DP wired mats proper jacketing shall be made (the most

suitable is metal steel jacketing)

FIRE PROTECTION OF VENTILATION DUCT

Description

It is vital to develop safe durable and reliable solutions

for ventilation systems as fire can easily spread from the

point of origin via ductwork Isover meets the highest

standards for fire protection providing excellent fire

resistance and top-rated reaction to fire performance

Rectangular ducts shall be insulated by Orstech 65 H

slabs with 40 mm thickness (60 mm for fire resistance EI

60 for a horizontal duct) circular ducts shall be insulated

by Orstech LSP PYRO lamella mats with 50 mm thickness

By these solutions fire resistances EI 15 30 45 and 60 S

have been certified to comply with EN 1366-1

Orstech system with fire resistance has been proven to

meet the requirements of all possible scenarios for fire

from the outside The scenarios can be identified by duct

orientation and duct shape (see table below) Horizontal

ducts normally serve one floor of a building Vertical

ducts normally serve between floors of a building All

scenarios have been done only with one layer Insulation

is fixed to a duct by welded pins Such solution is time

and material saving

Metal ductworkThe steel duct is constructed in sections of galvanised

steel sheet or stainless steel sheet minimum 08 mm thick

(standard duct sheeting for rectangular ducts specified

in DIN 24190 for circular ducts in DIN 24145) Maximum

duct size for which classification protocol is valid is 1250

mm (width) x 1000 mm (height) for rectangular duct or

diameter up to 1000 mm for a circular duct

At each cross joint flanges are fastened to the duct

with spot welds at 150 mm nominal centres

Use a ceramic tape gasket and fire-stopping mastic

between the flanges to seal the joints

Flanges are bolted together with an M10 steel nut

and bolt at each corner

Fasten the flanges together with steel clamps with

bolts M8 (see the figure) in quantity of 3 clamps per 1

meter of the flange length

Drop rods and hangers

Rectangular ducts are suspended by threaded rods and

channel section bearers A duct shall be hung with asuspension system which is independently fire rated

according to EN 1363-1 Certificated suspension system

MUPRO is recommended for the purpose Each steel

hanger consists of two threaded drop rods minimum

M10 and a channel section bearer 3840 mm Fasten

the bearer to the drop rods using hexagonal nuts and

washers The drop rods can be positioned either inside

the insulation material or outside If drop rods are outside

there is no need to insulate them separately The bearers

are positioned inside the insulation material

Circular ducts are suspended by MUumlPRO steel hangerswhich consist of two threaded drop rods minimum

M10 and a two-part industrial circular band The ends

of each band section are bent outwards Fasten the band

sections together and attach them to the drop rods with

hexagonal nuts and washers Place these hangers inside

the insulation The rods do not need to be protected by

insulation

When fixing them to a concrete construction use all-

steel expanding anchors to fasten the threaded rod

hangers to concrete soffits The anchors should penetrate

the concrete by at least 60 mm When fixing to a steel

supporting construction drill a hole through the steel

member allowing the drop rod to be supported by a steel

nut and washer above If a clamp type fixing is used the

clamp must be steel suitable for the purpose It should

pass around the steel member and be fastened back on

itself Clamps that rely on friction to hold them in place

are not suitable

Insulation

Rectangular ducts are insulated by Orstech 65 H slabs

(with apparent density 65 kgm3 and with one-sidedaluminium foil facing) with 40 mm thickness (60 mm

for fire resistance EI 60 for a horizontal duct) Circular

ducts are insulated by lamella mats Orstech LSP PYRO

with 50 mm thickness Insulation slabs (lamella mats)

need to be cut to fit the duct as tightly as possible the

insulation may need to be cut to fit around flanged duct

joints Install the insulation so that one slab (lamella

mat) is adjacent and tightly fitted against the other No

gaps must be present between butt joints of insulation

Insulation can be easily cut with a standard laggers knife

There is no need for adhesive on joints All the joints shall

be sealed by aluminium tape For rectangular ducts in theposition of flange the slabs are snick first 15 mm of the

thickness to avoid lifting of the slabs Butt joints should

be positioned out of flanges Fire protective insulation for

circular ducts does not require usage of a wire net mesh

on the outer side of insulation

Stud welded pins

The insulation is fixed to the duct using steel pins 27 mm

to 3 mm nominal diameter and spring steel washers

minimum 30 mm diameter The length of pin should

be equal to the insulation thickness The orientational

number of pins is 16 piecesm2 for rectangular ducts and14 piecesm2 for circular ducts

Recommended distance from duct edges and joints is

80 mm 50 mm from flanges

Wallfloor penetration

At wallfloor penetration one must insure the same fire

resistance of ventilation duct as has the fire separation

to avoid the spreading of fire from one compartment to

other via a duct This is possible by two basic principles

or their combinations - install a fire damper at the

penetration point or use insulation with fire resistancewhere the crucial thing is the fire-stopping The fire-

stopping is from the second insulation layer with the

width of 150 mm from both side of fire separation

The same general principle is used for both rectangular

and circular ducts regardless of orientation Place

the duct in the penetration of the construction with

approximately 10 mm gap between insulated duct and

opening Before installing the fire-stopping with the

same insulation thickness as is used for the first layer

pack the space between the duct and partition with

as many pieces of insulation as possible Ensure tight

compression in order to completely fill the opening This

must be done because system ORSTECH Protect does

not require stiffeners inside the duct Then install thesecond insulation layer so that it is adjacent and tightly

fitted against the penetration The insulation must be

cut leaving excess length so that it exerts some pressure

between the penetration and the last fitted piece of

insulation

The second layer is fixed by welded pins with length

equal to double insulation thickness The second layer for

circular ducts (lamella mats) is clamped with 1-2 wires

with a diameter 16 mm Then the insulation is secured

to the duct by welded pins

A inovative solution is the considerable simplification of

a fire-stopping concept There is no need to use any kind

of stiffener either inside or outside of the duct A great

advantage is to mount the whole ventilation section

at once and the wall itself can be placed anywhere

Therefore the position variability of fire separation is

provided No glue or mastic is needed at wallfloor

penetrations

Fire classification

ORSTECH Protect insulation with fire resistance has

been tested by the fire testing laboratory Pavus as an

authorised body AO 216 Classification protocols on the

request

Fire protection system ORSTECH Protect has been tested

in accordance with EN 1366-1 Maximum size for the

rectangular duct is 1250 x 1000 mm and for the circular

duct up to diameter 1000 mm If a duct has bigger

dimensions the certificate connected to the standard

cannot be used

capabilities

for retrofitting purposes

Insulation is usually fixed by mechanical fasteners - by

studs or pins Spacing between them is dependent on the

design of the vessel its surface temperature fire hazard

potential involved and presumptive loading Each slab

should be fixed by minimally two pins

BOILER INSULATIONInsulations for boilers kettles and ovens are one of

the most demanding applications in industry because

these units are operating at very high temperatures

Good insulation not only saves energy considerably but

the main purpose is personal protection against burn

According to the surface shape and temperature are used

either slabs with higher densities Orstech 65 to 110 (for

boilers with flat surfaces) or wired mats Orstech DP 65 to

DP 100 (for boilers with cylindrical parts)

Boiler walls are exposed to very high temperatures

(usually around 500 or 600 degC) Therefore it is essential

to use mechanical fasteners for the fixing of insulation

to the surface Insulation for boilers is done in at least

two layers each layer must be staggered when applied

Each layer must be secured in place before the next is

applied A product with high density should be placed as

the first layer because it has a higher maximum surface

temperature (higher resistance against high operating

temperatures) and better insulation performace than

products with lower densities

CHIMNEY INSULATION

Insulations for prefabricated chimneys are directly

supplied by producers of such systems In cooperation

with specialized wholesale companies we offer slabs

with multi-plate stripes which allow easy and perfect

application for prefabricated chimneys suitable both

for stainless steel chimney liners as well as with other

brands of chimney lining systems The main advantage

is the time saving during the installation in comparison

with the use of lamella mats and horizontal orientation

of fibres (better thermal conductivity) Insulation

dimensions ie thickness of slabs and groove dimensions

dependent on the chimney diameter are supplied

according to customer needs

For non-prefabricated chimneys are mostly used wired

mats Orstech DP or slabs Orstech 90 or 110 (for chimneys

with rectangular cross-section)

TECHNOLOGICAL APPLIANCEINSULATIONWhere big quantities of energy is used eg within

petrochemical paper and pulp industries thermal

insulation is necessary in order to reduce expensive

energy losses Tanks vessels exhausts exchangers

and technological piping are appliances that are often

working at high temperatures Good insulation will save

energy considerably which will benefit the environment

and keep the working costs down At the same time

the insulation will reduce temperature fall which could

disturb the production process

Proper insulation can be chosen in accordance with

dimension surface temperature the manner of fixing

and requirements for jacketing For pipes and cylindrical

parts are used lamella mats Orstech LSP H and Isover

ML-3 (only for temperatures up to 250 degC) or wired mats

Orstech DP For appliances and vessels with rectangular

shapes Orstech slabs are suitable (type according to a

surface temperature) Slabs can have aluminium facing

If insulation is done in more than one layer each layer

is staggered when applied Each layer must be secured

in place before the next is applied The decision to use

multiple layers may be made for one or more of the

following reasons

HEAT FLOW TRANSMISSION

Heat transfer is carried out by three heat transmission

modes conduction convection and radiation

Conduction

Heat transfers from warmer surface to colder through

solid material or gas (by fibres in mineral wool

insulations) The more insulant the material the less

the conduction

Convection

Transfer of heat caused by air movements (because of

temperature and density gradient) Hot air moves up

and heat dissipates The quieter the air the less the

convection Convection can be natural (when calculating

insulation inside the building) or forced (for calculation

outside where wind blows)

Radiation

Each material absorbs or emits thermal radiations

depending on its temperature and its emissivity Unlike

conduction or convection heat can be transferred by

radiation also in a vacuum When radiation is absorbed

or reflected there is less thermal transfer Measure of

radiating capacity of a material is emissivity ε Absolute

black body has the highest emissivity (ε = 1) Rough

and dark surfaces approaches such value (for example

mineral wool insulation without jacketing ε = 094)

contrary to bright and smooth surfaces that have very

low emissivity (for example polished aluminium foil ε

= 005) For design it is necessary to take into account

that covering of the bright surface with dust will

increase emissivity significantly

These three transport mechanisms are applied in

two very important quantities ndash surface heat transfer

coefficient α and thermal transmittance U

Thermal insulations impede conduction convection and

radiative effects

by creating a thermal barrier against conductionby suppressing air movements

by limiting radiative effects

Surface heat transfer coefficient

Two heat transmissions (convection and radiation)

influence the heat transfer coefficient α [W(m2middotK)] The

higher the heat transfer coefficient the higher the heat

flow rate from a warm surface

Thermal transmittance

Thermal transmittance (also called Overall heat transfer

coefficient) U (for flat surfaces [W(m2middotK)] for pipes [W

(mmiddotK)]) is inverted value of thermal resistance and it

takes into account the influence of all heat transmission

modes (conduction convection and radiation)

INSULATION SYSTEM DESIGN

GENERAL

An insulation system is the combination of insulations

finishes and application methods which are used toachieve specific design objectives Among these are

Energy savings

Reduced operating costs

Condensation control

Chemical compatibility with the metals being

insulated the atmosphere to which the system

will be exposed and the various components of the

insulation system itself

Protection of mechanical and insulation systems

from mechanical abuse and atmospheric damage

Personnel protection

Fire protection

Sound control

Future requirements for access to piping fittings etc

Accommodation to limited clearances or work space

While there are several choices of insulation materials

which meet basic thermal and cost-effective

requirements of an installation choices become more

limited with each additional design objective that

comes into play

INSULATION THICKNESS CALCULATION

When calculating the thickness of the insulation it isessential to put in appropriate boundary conditions lt

should be noted that the steady-state calculations are

dependent on boundary conditions Often a solution

at one set of boundary conditions is not sufficient to

characterize a thermal system which will operate in a

changing thermal environment (process equipment

operating year-round outdoors for example) In such

cases local weather data based on yearly averages or

yearly extremes of the weather variables should be

used for the calculations

The heat flow through a surface at any point is a function

of several variables which are not directly related

to insulation quality Among others these variables

include ambient temperature movement of the air

roughness and emissivity of the heat flow surface and

the radiation exchange with the surroundings (often

including a great variety of interest) For the calculation

of dew formation variability of the local humidity is animportant factor

Insulation desigh criterion

Apart from a choice of suitable insulation material

for given application it is essential to design proper

insulation thickness It can be determined from two

points of view

Heat loss minimalisation it means reaching the highest

possible economic savings (ideally to calcutate economic

insulation by so- called optimalisation)

Maximum surface temperature (personal protection

against burn) It is usually prescribed by nationallegislation Usual maximum surface temperature is

50 degC if the surrounding air temperature is 25 degC If the

air temperature is different temperature difference

between surface and surrounding air should be up to

25 degC Outdoor piping shall be controlled for maximum

surface temperature every time for summer period

(in the Central Europe calculation air temperature is

30 degC) In boiler rooms surrounding air temperature is

minimally 35 degC

Parameters influencing insulation thick-

ness designHeat flow from the insulation surface is a function of

several parameters which do not relate directly to the

quality of the insulation Here are several parameters

that influence design

thermal conductivity of the insulation material

medium temperature

ambient temperature

external heat transfer coefficient

ECONOMIC THICKNESS

The most substantial return on an investment ininsulation is in energy savings over a period of time

Thermal insulation is one of the most if not the most

significant technology used to conserve energy thereby

reducing pollution Rising energy costs guarantee an

increasing return on any investment made in insulation

In fact it costs less to insulate than not to In the case

of steam process and heat the difference in capital

investment necessary to provide equipment for the

extra steam capacity needed on underinsulated systems

and that investment necessary to insulate plus the

cost of insulation still represents a significant capital

investment savings That insulation saves money is not

the issue here The issue is how much

httpslidepdfcomreaderfullcatalogue-of-technical-insulations-2013-10-598-en 828

Economic thickness calculations are based on the law

of diminishing returns Because no insulation material

can completely stop the flow of heat each increment ofinsulation added to the thickness saves only a percentage

of the heat which has escaped through the underlying

insulation Therefore each increment of insulation

saves less than the one before it and must be evaluated

against the cost of installation to determine if it is a

ldquogood investmentrdquo It is possible to determine how much

insulation applied to a given system will repay its initial

costs in a specified time This point is reached when the

cost of the last incremental of insulation added is offset

by the savings generated by that increment

Refer to the stetch on the left The vertical scale is the

annual cost The horizontal scale is insulation thickness

As the insulation thickness increases from 0 the cost of

heat loss through the insulation decreases Note that this

cost (line B) tends to approach a horizontal line at high

thicknesses As the insulation thickness increases the

cost of the insulation also increases (line A) The total

annual cost at any insulation thickness is the sum of the

cost of the insulation and the cost of the lost heat (line

C) Line C goes through a minimum value of total annual

cost at the Economic thickness

With thicknesses less than the economic thickness the

total annual cost is higher because of the higher valueof the cost of lost heat With thicknesses higher than

the economic thickness the total annual cost is higher

because of the higher value of the cost of the insulation

In the case of computer results each pipe size will be

listed with the recommended thickness as well as

the average heat savings (as compared to a pre-listed

thickness or bare surface whichever chosen) and the

present value of the heat saved

In order to use any of the available manuals tables

or computer programs the two cost factors (cost of

lost energy and cost of insulation) must be found Thefollowing data is generally provided by the investor

Cost of lost energy

This factor is derived from the combination of the

rate of energy transfer the cost of energy and the

operational hours per year of the building Computing

the rate of energy transfer requires surface and

ambient temperatures thermal conductivity of the

chosen insulation the maximumminimum thickness of

insulation to be considered surface emissivity and last

but not least consideration of surface orientation (i evertical horizontal) and wind (air) velocity

Cost of insulation

This factor is derived from computing a bdquounit installed

price of insulationldquo with the total cost annualized overthe projectacutes life The unit installed price is a combination

of the cost of materials cost of labor and worker

productivity This is a sensitive variable in the economic

thickness calculation Only the roughest of regional

averages are available As a result care must be taken not

to perceive these estimates as fixed budget prices used

for installing insulation Material prices are related to the

volume and cost of the insulation jacketing securement

finishing and structural support material used Also

included in this figure are storage and handling costs to

the contractor Labor costs vary regionally and include

wages fringe benefits per diem and travel expensesas well as overhead and profit Labor production varies

with pipe size complexity number of layers necessary

accessibility of piping and surfaces type of materials

used and general working conditions Other costs

involve the job size and increase with the magnitude of

the job They include the preparation scaffolding clean-

up and tear-down costs supervision costs and general

overhead

MAXIMUM SERVICE TEMPERATURE

MST is determined in a laboratory by testing under de-

fined conditions which are dependent upon the form

of delivery and which are laid down in EN 14 706 (for

wired or lamella mats slabs and felts) and EN 14 707(for pipe sections and segments) MST is determined

by establishing the temperature and time related de-

crease in thickness in one-sided heating For the test

the sample shall take a load of 500 Pa The sample is

heated with a transient of at least 5 Kmin The hot-

face temperature must be maintained for 72 hours at

the expected maximum service temperature At the

maximum service temperature no test result must dis-

play a deformation under load of more than 5

In data sheets of different producers (not only mineral

wool) you will often find MST and value which is not

measured accordance to EN 14 706 This temperature

is only assumed When using such temperature there

is a danger of insulation degradation mainly insulation

thickness If mineral wool product has MST 700 or 750 degC

in its data sheet you can be sure that the material will

not withstand such temperature without degradation

of assessed properties Such temperatures shall not

be used Producers should leave field of assumed MST

and test their products to be able to use declared

MST according to EN 14 706 It is an outstandingimprovement compared to the past because individual

products on the European market can be compared to

each other according to standards valid in the EU

Slabs wired and lamella mats Orstech are certificated

according to valid European standards they are

regularly tested in testing laboratory FIW Muumlnchen

according to VDI 2055 and AGI Q 132 Maximum service

temperatures for various products can be found at the

end of the catalogue in the chapter Isover Products on

page 21)

EVAPORATION OF BINDERS

Binders and greasing agents in mineral wool products

dissolve and evaporate in areas with temperatures

higher than 150 degC Binder evaporation does not have any

influence on thermal properties only the compactness

of a material is decreased If proper underconstruction

is made there is almost no danger of insulation slide

down But if too small insulation thickness or improper

type of insulation is used (mostly insulation with too

low density for too high temperatures) danger of binder

evaporation in the whole thickness is possible with

consequent insulation slide down In this case no well

made underconstruction will help Insulation will not

work any more In the outer colder areas no dissolution

and evaporation take place

FIRE PERFORMANCE

FIRE ndash a chemical reaction involving rapid oxidation or

burning of a fuel occurs only when three elements are

present in the proper conditions and proportions

FUEL ndash Fuel can be any combustible material - solid

liquid or gas Most solids and liquids become a vapour

or gas before they burn

OXYGEN ndash The air we breathe is about 21 oxygen Fire

only needs an atmosphere with at least 16 oxygen

HEAT ndash Heat is the energy necessary to increase the

temperature of the fuel to a point where sufficient

vapours are given off for ignition to occur

Fire development depends mostly on room geometry

and ventilation the fuel type the amount and surface

area of the fuel Fire is often discussed in terms of the

temperature development and can be divided into

different stages incipience (ignition) growth flashover

fully developed fire and decay

How materials behave in the early stages of a fire from

ignition to flashover (the spontaneous ignition of hot

smoke and gasses) needs to be assessed at the design

stage for buildings and also for plants and equipment

Euroclasses a new European harmonised classification

system for materialsrsquo reaction to fire in most Europeancountries replaced the old national standards The

Euroclass fire classification covers not only materials

used in building structures but it is being extended also

to technical insulations to cover building equipment

and industrial installations This will help to compare

the reaction to fire of different thermal insulation

materials

The classification levels are A1A2 (completely non-

combustible) B C D E and F A1A2 corresponds to

the safest situation E would be the most dangerous

situation and F would mean not classified

ISOVER mineral wool insulations are totally non-

combustible and completely fire safe achieving

Euroclass A1 fire rating (A2 for products with facing)when classified in accordance with EN 13501-1 One

of the most important issues studied under reaction to

fire performance is the potential for flashover to occur

which can lead to a fire spreading uncontrollably Isover

stone wool is not susceptible to flashover

This is a guide to common building materials and their

likely Euroclassification

Check with individual product manufactures for spedific

product specifications

REACTION TO FIRE

Smoke and flaming droplet risk(1) In the EU classification system for reaction to fire

a construction product will be classified as Euroclass A1

A2 B C D E or F depending on its tendency to burn

(2) The product testing will provide data represented

by the signs s1 s2 or s3 which indicate the tendency

to release smoke Smoke causes over 60 of deaths in

fire across the EU The measurement of smoke release

has been put into these 3 broad bands that can be

translated as ldquolittle or no smokerdquo s1 - rdquoquite a lot of

smokerdquo s2 - rdquosubstantial smoke releaserdquo s3

(3) Some construction products like these made of

polystyrene can melt and ignite to form Flaming

Droplets Wooden products on the other hand will tend

to char before the char falls away as Flaming Particles

to expose more material

These rdquoflaming dropletsparticlesrdquo will tend to

initiate new fires away from the original point of

ignition and must be considered when the products

are used horizontally in ceiling or roof applications

flaming dropletsparticles as d0 (none) d1 (some) and

d2 (quite a lot)

FIRE PROTECTION DESIGN FOR VENTILATION DUCTS

Produced with the stone wool technology of Isover

fire protection system ORSTECH Protect is mineral

wool that combines all the advantages of conventionalthermal and acoustic insulation with top level of fire

safety Mineral wool insulations have the melting point

higher than 1000 degC From the fire protection point of

view products Isover are one of the safest materials

ORSTECH Protect consists of slab or lamella mat

solutions offering up to one hour fire protection for

both vertical and horizontal applications of rectangular

and circular ductwork systems

Passive protection of ventilation ducts is possible by

two basic means

Installed a fire damper into the duct to the place of

fire separation

Use a fire protection insulation system which is

tested according EN 1366-1 and has a classification

protocol in accordance with EN 13 501-3 This second

case is covered by insulation system ORSTECH

Protect

LEGISLATION

Air duct which shall resist the spread of fire from one

compartment to another is tested according to EN

1366-1 The standard can be applied to vertical and

horizontal ducts with or without branches for fire inside

or outside the duct The test measures the time period

for which ducts of specified dimensions suspended as

they would be in practice satisfy criteria when exposed

to fire from inside or outside (separately)

This standard is used in conjunction with EN 1363-1

which prescribes requirements for the determinationof fire resistance of various components of building

structures which are exposed to standard fire

conditions In this standard there are failure criteria

whereby it is possible to evaluate the ability of a tested

duct to prevent fire spread due to the destruction of

the duct (integrity failure E) heat transfer (insulationfailure I) and prevention of the smoke penetration

(smoke leakage S) Fire protection is expressed by time

in minutes for which failure criteria are fulfilled

Designation itself is then done according to

classification standard EN 13 501-3 Classification

states if criteria are fulfilled for fire outside (marking

o rarr i) valid for duct type A or fire inside (marking

irarr o) or from both directions (iharr o) valid for duct type

B and if this is valid for a horizontal duct (marking ho)

or a vertical one (ve) or both (ve ho) Eg class bdquoEI 30 S

ndash ve ho (orarr i) Sldquo represents duct capability to maintain

integrity insulation and smoke leakage for time period

of 30 minutes under fire exposure from outside both

for vertical and horizontal positions

MAXIMUM DUCT SIZES

Maximum size is according to EN 1366-1 for rectangular

duct 1250 x 1000 mm and for circular duct up to

diameter 1000 mm If a duct has bigger dimensions the

classification protocol cannot be used

ACOUSTIC PERFORMANCE

Noise is a sound which impacts negatively on the

surroundings Noise levels emanating from HVAC

services (pipework ductwork and air handlingequipment) and other services can be significantly

reduced with the use of Isover products which will

help to achieve acceptable environmental noise levels

Isover insulations are due to its fibre structure an ideal

material for sound attenuation not only for industrial

application The degree of sound insulation will depend

upon the application the thickness of insulation used

and the nature of any finish used to clad over the

installation In suitable frequencies they can absorb up

to 95 of the sound energy (α = 095)

SOUND ABSORPTIONWhen a sound wave strikes a surface the sound energy

is broken down into transmitted energy (through the

material) converted energy (usually heat) and reflected

energy (back towards the source of the sound)

The more absorbent the material the less sound is

reflected That part of sound energy which is converted

and transmitted is usually expressed as an absorption

coefficient α

The absorption coefficient for a material varies with

the frequency An absorbent layer of mineral wool

has the best absorption capacity in medium and high

frequencies The absorption in low frequencies is

improved by increasing the thickness or by providing an

air gap behind the absorbent layer

Examples of the effectiveness of Isover products in noise

control are given in the following table

ABSORPTIVE STRUCTURES

The most common task in room acoustics is to attenuate

or cancel some frequencies or a whole frequency band

This is possible to realise by using convenient absorptive

material or structures which are frequency-dependent

In this way we can control not only absorption ie

reverberation time but also suppress or completely

remove unpleasant sounds

In a porous material acoustic absorption is mainlycaused by friction in pores ie friction between

oscillating particles and the surface of pores Since the

energy loss due to friction is proportional to the length

of the path the most absorption will occur when the

porous material is placed in a position where the particle

displacement is the largest (maxima displacement)

When sound strikes a rigid wall like concrete for

example a standing wave result and the maxima of

particle displacement appear at the distances λ14

critical distances which must be covered by adsorbers

ie layers with thicknesses d1 = λ

14 d

2 = 3λ

24 d

3 = 5λ

34

In short an absorber with a thickeness d placed directly

on the solid structure will effectively attenuate only

those frequencies where f ge c4d (c is the velocity of

sound 340 ms) For example insulation thickness

of 50 mm wil l reliably attenuate frequencies higher

than 1700 Hz thickness 100 mm then already from

frequencies 850 Hz The higher the frequency the

shorter the wave length and better attenuation

An absorbing layer tightly adjacent to a solid structure

has nevertheless one disadvantage To attenuate

low frequencies it would be necessary to use verythick layers (for example for attenuation of 500 Hz a

thickness of about 20 cm would be necessary) Therefore

acoustic tiles can hardly attenuate low frequency noise

(frequencies lower than 100 dB such as noise from

discotheques)

Fortunately it is possible to avoid expensive acoustic

tiles with high thickness If we use a very thin layer

and place it just in the position of the displacement

maximum of a chosen frequency this chosen frequency

and its odd multiples will be attenuated Acoustic

tiles thus work as a selective frequency filter On theselective basis also other acoustic attenuators work

namely membranes oscillating plates and resonators

ACOUSTICS INSULATIONS

Isover stone wool products with a high longitudinal air-

flow resistance (up to 95 kPasm2) and uniform porosity

(93 ndash 99 ) are used as sound attenuation insulations

In suitable frequencies they can absorb up to 95 of

the sound energy (α = 095) Sound attenuation in a

construction is related to elastic properties of Isover

mineral wool insulations and their low modulus of

elasticity (they have low dynamic toughness and

therefore they are much more suitable for acoustic

purposes in comparison with foam plastics)

Sound attenuation properties of Isover products are

characterised by an absorption coefficient α which

can be found in the table for three thicknesses andsix frequencies According to a given noise spectrum

it is possible to design a sound attenuation structure

of which our material is only a part Since we provide

only insulation material we launch only absorption

coefficients Final attenuation will be dependent on

the whole designed construction (considering also

supporting construction hangers) and assembly

Isover does not design sound attenuation and thus it

is necessary to ask specialists who are able to design a

proper structure

Generally we can say that transmission loss is higher

for constructions with higher plane weight therefore

in most cases insulation with higher density has

better sound attenuation (eg slabs Orstech 65 90

110 Isover FireProtect 150) than insulation with lower

density (eg Orstech 45) Slabs can be manufacturedwith a facing ndash glass black tissue

GENERAL RULES FOR USING ISOVER INSULATIONS

Between insulated piping sufficient distances must

be kept

Valves should be placed without needing to go on theinsulated pipes when handling them

Spindle of valves should not be installed in an upward

direction to avoid water leakage into the insulation

Surfaces before insulating must be clean and dry It

is not possible to insulate wet or frostbitten surfaces

which may later cause damages of insulation or

insulated surfaces

Dirt and rust must be rubbed down from untreated

carbon steels

Smear and oils must be removed by detergents or

solvents from insulated surfaces

Stainless steel surfaces must not be cleaned by

detergents or solvents with chloride content They

may be cleaned only by stainless steel brushes

Chloride solution attacks stainless steel surface and

causes stress corrosion cracking in the material With

increasing surface temperature the danger of stress

corrosion cracking is raised

Piping and equipment from stainless steel can be

insulated only by mineral wool insulation in AS

quality Such material can have maximum content

of chloride ions of 10 mg in 1 kg of the insulation

material

It is necessary to avoid contact of metals which can

cause galvanic corrosion (Cu-Zn Fe-Al)For operating temperatures higher than 600 degC

aluminium jacketing should not be used

Self-tapping screw bold or rivet should be from the

same material as the jacketing

Surfaces with temperatures higher than 500 degC

should be insulated by more insulation layers in a

way that each layer has a different apparent density

Material with higher density insulates better under

higher temperatures than material with lower

density therefore insulation with higher density is

placed closer to the hot side Under low operating

temperatures thermal performance is almost equalSafety working principles must be kept for insulation

assembly

Isover products are packed into PE foil They must be

transported in covered vehicles under such conditions

to avoid moistening or other degradation They must

be stored in covered places

Wired mats

After the cutting of needed length the wired mat shall

be tightly wrapped on the pipe Wired matsrsquo butt jointsshould be in close contact to each other to ensure no

gaps between mats For multiple layer construction

each layer is staggered when applied Each layer must

be secured in place before the next is applied Individual

mats are bound together with a wire with minimal 07

mm thickness Alternatively wired hook or stainless

steel bands (with minimum width of 10 mm) can be

used Maximum distance between hooks is 150 mm

The decision to use multiple layers may be made for one

or more of the following reasons

to provide compensation for pipe expansion andcontraction

to reduce heat flow by staggering joints thus creating

a more thermally efficient installation

to achieve thickness in excess of manufacturersrsquo

capabilities

for retrofitting purposes

Lamella mats

Lamella mats Orstech LSP H consist of mineral wool

lamellas which have been glued to aluminium foil

reinforced with a glass fibre grid and these fibres are

predominantly perpendicular to the surface of themat Compressive strength but thermal conductivity

too are increased compared to mats with a fibre

orientation parallel to the surface (wired mats) Due

to its compressive strength resistance they have less

demands for undeconstruction (less thermal bridges)

in comparison with wired mats Temporary securing in

place is done by aluminium tapes final fixing shall be

done by a baling wire

Protective coverings

The efficiency and service of insulation is directly

dependent upon its protection from moisture entry andmechanical and chemical damage Choices of jacketing

materials are based upon the mechanical chemical

thermal and moisture conditions of the installation

as well as cost and appearance requirements The

basic function of the weather protection is to protect

the insulation from rain snow sleet wind solar

radiation atmospheric contamination and mechanical

damage With this definition in mind several service

requirements must be considered

PIPING INSULATION

For domestic hot water piping with smaller diameters

insulation pipe sections which are covered withaluminium foil are ideal Pipe sections with a facing

have a self-adhesive overlap in a longitudinal joint

to ensure perfect enclosure of a pipe section It is

recommended to secure pipe sections by an aluminium

tape or by galvanized wire transversely They are usually

knotted three times per meter more for pipe sections

with higher diameter Higher diameters should be

secured either by wire or by metal band (at least two

bands per meter)

Pipings with bigger diameters are most commonly

insulated by lamella mats Orstech LSP (stone woolinsulation) or Isover ML-3 (glass wool insulation)

eventually by wired mats Orstech DP (especially for higher

temperatures) Lamella and wired mats are also suitable

for appliances and vessels (both ends and cylindrical

parts) residential heating systems and air ducts

Internal mechanical forces ndash expansion and contraction

of the pipe or vessel must be considered because the

resulting forces are transferred to the external surface ofthe weather barrier Ability to slide elongate or contract

must be provided

External mechanical forces ndash mechanical abuse (ie

tools being dropped abrasion from wind-driven sand

personnel walking on the system) inflicted on a pipe or

vessel needs to be considered in design This may affect

insulation type as well as the weather barrier jacketing

type

Chemical resistance Some industrial environments may

have airborne or spilled corrosive agents that accumulate

on the weather barrier and chemically attack the pipe or

vessel jacketing Elements that create corrosive issues

must be well understood and accounted for Insulation

design of coastal facilities should account for chloride

attack

Galvanic corrosion Contacts between two different

types of metal must be considered for galvanic corrosion

potential Similarly water can act as an electrolyte and

galvanic corrosion can occur because of the differentpotential of the pipe and vessel and a metal jacketing

Materials used as weather barriers for insulation

Typical metal jacketing materials bare aluminium coated

aluminium stainless steel painted steel galvanized steel

aluminium-zinc coated steel

Typical polymeric jacketing materials polyvinyl chloride

(PVC) polyvinyliedene chloride (PVDC) polyisobutylene

multiple-layer composite materials (eg polymericfoil

mesh laminates) fabrics (silicone-impregnated fibreglass)

Fittings valves

Insulation of fittings valves flanges and couplings is

the most time consuming and often expensive aspectof commercial and industrial insulation But it is crucial

to insulate also these parts properly otherwise most of

energy will be transported by these thermal bridges For

example for 200 degC medium heat loss of one uninsulated

valve corresponds to one meter of uninsulated pipe or

ten meters of uninsulated pipe

Fittings are items used to change size direction of flow

level or assembly of piping They may be of the screwed

sweat or welded types Valves are any of various devices

that regulate liquid or gas flow and they may be of the

screwed sweated flanged or welded types Flanges areprotruding rims and edges of the screwed or sweated

type used with fittings valves couplings etc And finally

mechanical couplings are devices used in assembly of

piping Screwed and flanged connections on fittings

valves couplings etc usually require oversized insulation

applications to compensate for the protrusions

Minimum spacing between pipes and

constructions

It is essential to ensure sufficient space between pipies

and between a pipe and a wall (minimally 100 mm)

Otherwise there is a great danger of creating a zone withalmost no cenvenction The result can be too high surface

temperature (needed personal protection against burn)

or possibility of condensation on cold piping Besides

mounting would have been more difficult

DUCTING INSULATION

Isover products are designed to provide high levels of

thermal acoustic and fire protection insulation in HVACductwork applications such as rectangular flat oval and

circular ductwork

The most suitable insulation materials for ducts are

felts KLIMAROL with aluminium foil facing lamella mats

Orstech LSP or Isover ML-3 wired mats Orstech DP or

slabs Orstech H with aluminium foil facing

Duct insulation mounting

Insulation is mostly fixed to the duct by welded pinsWhen using Orstech H slabs with aluminium facing all

the joints shall be sealed with aluminium tape If a steel

clamping band is used it is necessary to use thin-walled

steel L-profiles to avoid trimming of the insulation If

using Orstech slabs without aluminium facing or Orstech

DP wired mats proper jacketing shall be made (the most

suitable is metal steel jacketing)

FIRE PROTECTION OF VENTILATION DUCT

Description

It is vital to develop safe durable and reliable solutions

for ventilation systems as fire can easily spread from the

point of origin via ductwork Isover meets the highest

standards for fire protection providing excellent fire

resistance and top-rated reaction to fire performance

Rectangular ducts shall be insulated by Orstech 65 H

slabs with 40 mm thickness (60 mm for fire resistance EI

60 for a horizontal duct) circular ducts shall be insulated

by Orstech LSP PYRO lamella mats with 50 mm thickness

By these solutions fire resistances EI 15 30 45 and 60 S

have been certified to comply with EN 1366-1

Orstech system with fire resistance has been proven to

meet the requirements of all possible scenarios for fire

from the outside The scenarios can be identified by duct

orientation and duct shape (see table below) Horizontal

ducts normally serve one floor of a building Vertical

ducts normally serve between floors of a building All

scenarios have been done only with one layer Insulation

is fixed to a duct by welded pins Such solution is time

and material saving

Metal ductworkThe steel duct is constructed in sections of galvanised

steel sheet or stainless steel sheet minimum 08 mm thick

(standard duct sheeting for rectangular ducts specified

in DIN 24190 for circular ducts in DIN 24145) Maximum

duct size for which classification protocol is valid is 1250

mm (width) x 1000 mm (height) for rectangular duct or

diameter up to 1000 mm for a circular duct

At each cross joint flanges are fastened to the duct

with spot welds at 150 mm nominal centres

Use a ceramic tape gasket and fire-stopping mastic

between the flanges to seal the joints

Flanges are bolted together with an M10 steel nut

and bolt at each corner

Fasten the flanges together with steel clamps with

bolts M8 (see the figure) in quantity of 3 clamps per 1

meter of the flange length

Drop rods and hangers

Rectangular ducts are suspended by threaded rods and

channel section bearers A duct shall be hung with asuspension system which is independently fire rated

according to EN 1363-1 Certificated suspension system

MUPRO is recommended for the purpose Each steel

hanger consists of two threaded drop rods minimum

M10 and a channel section bearer 3840 mm Fasten

the bearer to the drop rods using hexagonal nuts and

washers The drop rods can be positioned either inside

the insulation material or outside If drop rods are outside

there is no need to insulate them separately The bearers

are positioned inside the insulation material

Circular ducts are suspended by MUumlPRO steel hangerswhich consist of two threaded drop rods minimum

M10 and a two-part industrial circular band The ends

of each band section are bent outwards Fasten the band

sections together and attach them to the drop rods with

hexagonal nuts and washers Place these hangers inside

the insulation The rods do not need to be protected by

insulation

When fixing them to a concrete construction use all-

steel expanding anchors to fasten the threaded rod

hangers to concrete soffits The anchors should penetrate

the concrete by at least 60 mm When fixing to a steel

supporting construction drill a hole through the steel

member allowing the drop rod to be supported by a steel

nut and washer above If a clamp type fixing is used the

clamp must be steel suitable for the purpose It should

pass around the steel member and be fastened back on

itself Clamps that rely on friction to hold them in place

are not suitable

Insulation

Rectangular ducts are insulated by Orstech 65 H slabs

(with apparent density 65 kgm3 and with one-sidedaluminium foil facing) with 40 mm thickness (60 mm

for fire resistance EI 60 for a horizontal duct) Circular

ducts are insulated by lamella mats Orstech LSP PYRO

with 50 mm thickness Insulation slabs (lamella mats)

need to be cut to fit the duct as tightly as possible the

insulation may need to be cut to fit around flanged duct

joints Install the insulation so that one slab (lamella

mat) is adjacent and tightly fitted against the other No

gaps must be present between butt joints of insulation

Insulation can be easily cut with a standard laggers knife

There is no need for adhesive on joints All the joints shall

be sealed by aluminium tape For rectangular ducts in theposition of flange the slabs are snick first 15 mm of the

thickness to avoid lifting of the slabs Butt joints should

be positioned out of flanges Fire protective insulation for

circular ducts does not require usage of a wire net mesh

on the outer side of insulation

Stud welded pins

The insulation is fixed to the duct using steel pins 27 mm

to 3 mm nominal diameter and spring steel washers

minimum 30 mm diameter The length of pin should

be equal to the insulation thickness The orientational

number of pins is 16 piecesm2 for rectangular ducts and14 piecesm2 for circular ducts

Recommended distance from duct edges and joints is

80 mm 50 mm from flanges

Wallfloor penetration

At wallfloor penetration one must insure the same fire

resistance of ventilation duct as has the fire separation

to avoid the spreading of fire from one compartment to

other via a duct This is possible by two basic principles

or their combinations - install a fire damper at the

penetration point or use insulation with fire resistancewhere the crucial thing is the fire-stopping The fire-

stopping is from the second insulation layer with the

width of 150 mm from both side of fire separation

The same general principle is used for both rectangular

and circular ducts regardless of orientation Place

the duct in the penetration of the construction with

approximately 10 mm gap between insulated duct and

opening Before installing the fire-stopping with the

same insulation thickness as is used for the first layer

pack the space between the duct and partition with

as many pieces of insulation as possible Ensure tight

compression in order to completely fill the opening This

must be done because system ORSTECH Protect does

not require stiffeners inside the duct Then install thesecond insulation layer so that it is adjacent and tightly

fitted against the penetration The insulation must be

cut leaving excess length so that it exerts some pressure

between the penetration and the last fitted piece of

insulation

The second layer is fixed by welded pins with length

equal to double insulation thickness The second layer for

circular ducts (lamella mats) is clamped with 1-2 wires

with a diameter 16 mm Then the insulation is secured

to the duct by welded pins

A inovative solution is the considerable simplification of

a fire-stopping concept There is no need to use any kind

of stiffener either inside or outside of the duct A great

advantage is to mount the whole ventilation section

at once and the wall itself can be placed anywhere

Therefore the position variability of fire separation is

provided No glue or mastic is needed at wallfloor

penetrations

Fire classification

ORSTECH Protect insulation with fire resistance has

been tested by the fire testing laboratory Pavus as an

authorised body AO 216 Classification protocols on the

request

Fire protection system ORSTECH Protect has been tested

in accordance with EN 1366-1 Maximum size for the

rectangular duct is 1250 x 1000 mm and for the circular

duct up to diameter 1000 mm If a duct has bigger

dimensions the certificate connected to the standard

cannot be used

capabilities

for retrofitting purposes

Insulation is usually fixed by mechanical fasteners - by

studs or pins Spacing between them is dependent on the

design of the vessel its surface temperature fire hazard

potential involved and presumptive loading Each slab

should be fixed by minimally two pins

BOILER INSULATIONInsulations for boilers kettles and ovens are one of

the most demanding applications in industry because

these units are operating at very high temperatures

Good insulation not only saves energy considerably but

the main purpose is personal protection against burn

According to the surface shape and temperature are used

either slabs with higher densities Orstech 65 to 110 (for

boilers with flat surfaces) or wired mats Orstech DP 65 to

DP 100 (for boilers with cylindrical parts)

Boiler walls are exposed to very high temperatures

(usually around 500 or 600 degC) Therefore it is essential

to use mechanical fasteners for the fixing of insulation

to the surface Insulation for boilers is done in at least

two layers each layer must be staggered when applied

Each layer must be secured in place before the next is

applied A product with high density should be placed as

the first layer because it has a higher maximum surface

temperature (higher resistance against high operating

temperatures) and better insulation performace than

products with lower densities

CHIMNEY INSULATION

Insulations for prefabricated chimneys are directly

supplied by producers of such systems In cooperation

with specialized wholesale companies we offer slabs

with multi-plate stripes which allow easy and perfect

application for prefabricated chimneys suitable both

for stainless steel chimney liners as well as with other

brands of chimney lining systems The main advantage

is the time saving during the installation in comparison

with the use of lamella mats and horizontal orientation

of fibres (better thermal conductivity) Insulation

dimensions ie thickness of slabs and groove dimensions

dependent on the chimney diameter are supplied

according to customer needs

For non-prefabricated chimneys are mostly used wired

mats Orstech DP or slabs Orstech 90 or 110 (for chimneys

with rectangular cross-section)

TECHNOLOGICAL APPLIANCEINSULATIONWhere big quantities of energy is used eg within

petrochemical paper and pulp industries thermal

insulation is necessary in order to reduce expensive

energy losses Tanks vessels exhausts exchangers

and technological piping are appliances that are often

working at high temperatures Good insulation will save

energy considerably which will benefit the environment

and keep the working costs down At the same time

the insulation will reduce temperature fall which could

disturb the production process

Proper insulation can be chosen in accordance with

dimension surface temperature the manner of fixing

and requirements for jacketing For pipes and cylindrical

parts are used lamella mats Orstech LSP H and Isover

ML-3 (only for temperatures up to 250 degC) or wired mats

Orstech DP For appliances and vessels with rectangular

shapes Orstech slabs are suitable (type according to a

surface temperature) Slabs can have aluminium facing

If insulation is done in more than one layer each layer

is staggered when applied Each layer must be secured

in place before the next is applied The decision to use

multiple layers may be made for one or more of the

following reasons

INSULATION SYSTEM DESIGN

GENERAL

An insulation system is the combination of insulations

finishes and application methods which are used toachieve specific design objectives Among these are

Energy savings

Reduced operating costs

Condensation control

Chemical compatibility with the metals being

insulated the atmosphere to which the system

will be exposed and the various components of the

insulation system itself

Protection of mechanical and insulation systems

from mechanical abuse and atmospheric damage

Personnel protection

Fire protection

Sound control

Future requirements for access to piping fittings etc

Accommodation to limited clearances or work space

While there are several choices of insulation materials

which meet basic thermal and cost-effective

requirements of an installation choices become more

limited with each additional design objective that

comes into play

INSULATION THICKNESS CALCULATION

When calculating the thickness of the insulation it isessential to put in appropriate boundary conditions lt

should be noted that the steady-state calculations are

dependent on boundary conditions Often a solution

at one set of boundary conditions is not sufficient to

characterize a thermal system which will operate in a

changing thermal environment (process equipment

operating year-round outdoors for example) In such

cases local weather data based on yearly averages or

yearly extremes of the weather variables should be

used for the calculations

The heat flow through a surface at any point is a function

of several variables which are not directly related

to insulation quality Among others these variables

include ambient temperature movement of the air

roughness and emissivity of the heat flow surface and

the radiation exchange with the surroundings (often

including a great variety of interest) For the calculation

of dew formation variability of the local humidity is animportant factor

Insulation desigh criterion

Apart from a choice of suitable insulation material

for given application it is essential to design proper

insulation thickness It can be determined from two

points of view

Heat loss minimalisation it means reaching the highest

possible economic savings (ideally to calcutate economic

insulation by so- called optimalisation)

Maximum surface temperature (personal protection

against burn) It is usually prescribed by nationallegislation Usual maximum surface temperature is

50 degC if the surrounding air temperature is 25 degC If the

air temperature is different temperature difference

between surface and surrounding air should be up to

25 degC Outdoor piping shall be controlled for maximum

surface temperature every time for summer period

(in the Central Europe calculation air temperature is

30 degC) In boiler rooms surrounding air temperature is

minimally 35 degC

Parameters influencing insulation thick-

ness designHeat flow from the insulation surface is a function of

several parameters which do not relate directly to the

quality of the insulation Here are several parameters

that influence design

thermal conductivity of the insulation material

medium temperature

ambient temperature

external heat transfer coefficient

ECONOMIC THICKNESS

The most substantial return on an investment ininsulation is in energy savings over a period of time

Thermal insulation is one of the most if not the most

significant technology used to conserve energy thereby

reducing pollution Rising energy costs guarantee an

increasing return on any investment made in insulation

In fact it costs less to insulate than not to In the case

of steam process and heat the difference in capital

investment necessary to provide equipment for the

extra steam capacity needed on underinsulated systems

and that investment necessary to insulate plus the

cost of insulation still represents a significant capital

investment savings That insulation saves money is not

the issue here The issue is how much

Economic thickness calculations are based on the law

of diminishing returns Because no insulation material

can completely stop the flow of heat each increment ofinsulation added to the thickness saves only a percentage

of the heat which has escaped through the underlying

insulation Therefore each increment of insulation

saves less than the one before it and must be evaluated

against the cost of installation to determine if it is a

ldquogood investmentrdquo It is possible to determine how much

insulation applied to a given system will repay its initial

costs in a specified time This point is reached when the

cost of the last incremental of insulation added is offset

by the savings generated by that increment

Refer to the stetch on the left The vertical scale is the

annual cost The horizontal scale is insulation thickness

As the insulation thickness increases from 0 the cost of

heat loss through the insulation decreases Note that this

cost (line B) tends to approach a horizontal line at high

thicknesses As the insulation thickness increases the

cost of the insulation also increases (line A) The total

annual cost at any insulation thickness is the sum of the

cost of the insulation and the cost of the lost heat (line

C) Line C goes through a minimum value of total annual

cost at the Economic thickness

With thicknesses less than the economic thickness the

total annual cost is higher because of the higher valueof the cost of lost heat With thicknesses higher than

the economic thickness the total annual cost is higher

because of the higher value of the cost of the insulation

In the case of computer results each pipe size will be

listed with the recommended thickness as well as

the average heat savings (as compared to a pre-listed

thickness or bare surface whichever chosen) and the

present value of the heat saved

In order to use any of the available manuals tables

or computer programs the two cost factors (cost of

lost energy and cost of insulation) must be found Thefollowing data is generally provided by the investor

Cost of lost energy

This factor is derived from the combination of the

rate of energy transfer the cost of energy and the

operational hours per year of the building Computing

the rate of energy transfer requires surface and

ambient temperatures thermal conductivity of the

chosen insulation the maximumminimum thickness of

insulation to be considered surface emissivity and last

but not least consideration of surface orientation (i evertical horizontal) and wind (air) velocity

Cost of insulation

This factor is derived from computing a bdquounit installed

price of insulationldquo with the total cost annualized overthe projectacutes life The unit installed price is a combination

of the cost of materials cost of labor and worker

productivity This is a sensitive variable in the economic

thickness calculation Only the roughest of regional

averages are available As a result care must be taken not

to perceive these estimates as fixed budget prices used

for installing insulation Material prices are related to the

volume and cost of the insulation jacketing securement

finishing and structural support material used Also

included in this figure are storage and handling costs to

the contractor Labor costs vary regionally and include

wages fringe benefits per diem and travel expensesas well as overhead and profit Labor production varies

with pipe size complexity number of layers necessary

accessibility of piping and surfaces type of materials

used and general working conditions Other costs

involve the job size and increase with the magnitude of

the job They include the preparation scaffolding clean-

up and tear-down costs supervision costs and general

overhead

MAXIMUM SERVICE TEMPERATURE

MST is determined in a laboratory by testing under de-

fined conditions which are dependent upon the form

of delivery and which are laid down in EN 14 706 (for

wired or lamella mats slabs and felts) and EN 14 707(for pipe sections and segments) MST is determined

by establishing the temperature and time related de-

crease in thickness in one-sided heating For the test

the sample shall take a load of 500 Pa The sample is

heated with a transient of at least 5 Kmin The hot-

face temperature must be maintained for 72 hours at

the expected maximum service temperature At the

maximum service temperature no test result must dis-

play a deformation under load of more than 5

In data sheets of different producers (not only mineral

wool) you will often find MST and value which is not

measured accordance to EN 14 706 This temperature

is only assumed When using such temperature there

is a danger of insulation degradation mainly insulation

thickness If mineral wool product has MST 700 or 750 degC

in its data sheet you can be sure that the material will

not withstand such temperature without degradation

of assessed properties Such temperatures shall not

be used Producers should leave field of assumed MST

and test their products to be able to use declared

MST according to EN 14 706 It is an outstandingimprovement compared to the past because individual

products on the European market can be compared to

each other according to standards valid in the EU

Slabs wired and lamella mats Orstech are certificated

according to valid European standards they are

regularly tested in testing laboratory FIW Muumlnchen

according to VDI 2055 and AGI Q 132 Maximum service

temperatures for various products can be found at the

end of the catalogue in the chapter Isover Products on

page 21)

EVAPORATION OF BINDERS

Binders and greasing agents in mineral wool products

dissolve and evaporate in areas with temperatures

higher than 150 degC Binder evaporation does not have any

influence on thermal properties only the compactness

of a material is decreased If proper underconstruction

is made there is almost no danger of insulation slide

down But if too small insulation thickness or improper

type of insulation is used (mostly insulation with too

low density for too high temperatures) danger of binder

evaporation in the whole thickness is possible with

consequent insulation slide down In this case no well

made underconstruction will help Insulation will not

work any more In the outer colder areas no dissolution

and evaporation take place

FIRE PERFORMANCE

FIRE ndash a chemical reaction involving rapid oxidation or

burning of a fuel occurs only when three elements are

present in the proper conditions and proportions

FUEL ndash Fuel can be any combustible material - solid

liquid or gas Most solids and liquids become a vapour

or gas before they burn

OXYGEN ndash The air we breathe is about 21 oxygen Fire

only needs an atmosphere with at least 16 oxygen

HEAT ndash Heat is the energy necessary to increase the

temperature of the fuel to a point where sufficient

vapours are given off for ignition to occur

Fire development depends mostly on room geometry

and ventilation the fuel type the amount and surface

area of the fuel Fire is often discussed in terms of the

temperature development and can be divided into

different stages incipience (ignition) growth flashover

fully developed fire and decay

How materials behave in the early stages of a fire from

ignition to flashover (the spontaneous ignition of hot

smoke and gasses) needs to be assessed at the design

stage for buildings and also for plants and equipment

Euroclasses a new European harmonised classification

system for materialsrsquo reaction to fire in most Europeancountries replaced the old national standards The

Euroclass fire classification covers not only materials

used in building structures but it is being extended also

to technical insulations to cover building equipment

and industrial installations This will help to compare

the reaction to fire of different thermal insulation

materials

The classification levels are A1A2 (completely non-

combustible) B C D E and F A1A2 corresponds to

the safest situation E would be the most dangerous

situation and F would mean not classified

ISOVER mineral wool insulations are totally non-

combustible and completely fire safe achieving

Euroclass A1 fire rating (A2 for products with facing)when classified in accordance with EN 13501-1 One

of the most important issues studied under reaction to

fire performance is the potential for flashover to occur

which can lead to a fire spreading uncontrollably Isover

stone wool is not susceptible to flashover

This is a guide to common building materials and their

likely Euroclassification

Check with individual product manufactures for spedific

product specifications

REACTION TO FIRE

Smoke and flaming droplet risk(1) In the EU classification system for reaction to fire

a construction product will be classified as Euroclass A1

A2 B C D E or F depending on its tendency to burn

(2) The product testing will provide data represented

by the signs s1 s2 or s3 which indicate the tendency

to release smoke Smoke causes over 60 of deaths in

fire across the EU The measurement of smoke release

has been put into these 3 broad bands that can be

translated as ldquolittle or no smokerdquo s1 - rdquoquite a lot of

smokerdquo s2 - rdquosubstantial smoke releaserdquo s3

(3) Some construction products like these made of

polystyrene can melt and ignite to form Flaming

Droplets Wooden products on the other hand will tend

to char before the char falls away as Flaming Particles

to expose more material

These rdquoflaming dropletsparticlesrdquo will tend to

initiate new fires away from the original point of

ignition and must be considered when the products

are used horizontally in ceiling or roof applications

The classification system ranks the level of release of

flaming dropletsparticles as d0 (none) d1 (some) and

d2 (quite a lot)

FIRE PROTECTION DESIGN FOR VENTILATION DUCTS

Produced with the stone wool technology of Isover

fire protection system ORSTECH Protect is mineral

wool that combines all the advantages of conventionalthermal and acoustic insulation with top level of fire

safety Mineral wool insulations have the melting point

higher than 1000 degC From the fire protection point of

view products Isover are one of the safest materials

ORSTECH Protect consists of slab or lamella mat

solutions offering up to one hour fire protection for

both vertical and horizontal applications of rectangular

and circular ductwork systems

Passive protection of ventilation ducts is possible by

two basic means

Installed a fire damper into the duct to the place of

fire separation

Use a fire protection insulation system which is

tested according EN 1366-1 and has a classification

protocol in accordance with EN 13 501-3 This second

case is covered by insulation system ORSTECH

Protect

LEGISLATION

Air duct which shall resist the spread of fire from one

compartment to another is tested according to EN

1366-1 The standard can be applied to vertical and

horizontal ducts with or without branches for fire inside

or outside the duct The test measures the time period

for which ducts of specified dimensions suspended as

they would be in practice satisfy criteria when exposed

to fire from inside or outside (separately)

This standard is used in conjunction with EN 1363-1

which prescribes requirements for the determinationof fire resistance of various components of building

structures which are exposed to standard fire

conditions In this standard there are failure criteria

whereby it is possible to evaluate the ability of a tested

duct to prevent fire spread due to the destruction of

the duct (integrity failure E) heat transfer (insulationfailure I) and prevention of the smoke penetration

(smoke leakage S) Fire protection is expressed by time

in minutes for which failure criteria are fulfilled

Designation itself is then done according to

classification standard EN 13 501-3 Classification

states if criteria are fulfilled for fire outside (marking

o rarr i) valid for duct type A or fire inside (marking

irarr o) or from both directions (iharr o) valid for duct type

B and if this is valid for a horizontal duct (marking ho)

or a vertical one (ve) or both (ve ho) Eg class bdquoEI 30 S

ndash ve ho (orarr i) Sldquo represents duct capability to maintain

integrity insulation and smoke leakage for time period

of 30 minutes under fire exposure from outside both

for vertical and horizontal positions

MAXIMUM DUCT SIZES

Maximum size is according to EN 1366-1 for rectangular

duct 1250 x 1000 mm and for circular duct up to

diameter 1000 mm If a duct has bigger dimensions the

classification protocol cannot be used

ACOUSTIC PERFORMANCE

Noise is a sound which impacts negatively on the

surroundings Noise levels emanating from HVAC

services (pipework ductwork and air handlingequipment) and other services can be significantly

reduced with the use of Isover products which will

help to achieve acceptable environmental noise levels

Isover insulations are due to its fibre structure an ideal

material for sound attenuation not only for industrial

application The degree of sound insulation will depend

upon the application the thickness of insulation used

and the nature of any finish used to clad over the

installation In suitable frequencies they can absorb up

to 95 of the sound energy (α = 095)

SOUND ABSORPTIONWhen a sound wave strikes a surface the sound energy

is broken down into transmitted energy (through the

material) converted energy (usually heat) and reflected

energy (back towards the source of the sound)

The more absorbent the material the less sound is

reflected That part of sound energy which is converted

and transmitted is usually expressed as an absorption

coefficient α

The absorption coefficient for a material varies with

the frequency An absorbent layer of mineral wool

has the best absorption capacity in medium and high

frequencies The absorption in low frequencies is

improved by increasing the thickness or by providing an

air gap behind the absorbent layer

Examples of the effectiveness of Isover products in noise

control are given in the following table

ABSORPTIVE STRUCTURES

The most common task in room acoustics is to attenuate

or cancel some frequencies or a whole frequency band

This is possible to realise by using convenient absorptive

material or structures which are frequency-dependent

In this way we can control not only absorption ie

reverberation time but also suppress or completely

remove unpleasant sounds

In a porous material acoustic absorption is mainlycaused by friction in pores ie friction between

oscillating particles and the surface of pores Since the

energy loss due to friction is proportional to the length

of the path the most absorption will occur when the

porous material is placed in a position where the particle

displacement is the largest (maxima displacement)

When sound strikes a rigid wall like concrete for

example a standing wave result and the maxima of

particle displacement appear at the distances λ14

3λ24 5λ

34 hellip from the surface of a room These are the

critical distances which must be covered by adsorbers

ie layers with thicknesses d1 = λ

14 d

2 = 3λ

24 d

3 = 5λ

34

In short an absorber with a thickeness d placed directly

on the solid structure will effectively attenuate only

those frequencies where f ge c4d (c is the velocity of

sound 340 ms) For example insulation thickness

of 50 mm wil l reliably attenuate frequencies higher

than 1700 Hz thickness 100 mm then already from

frequencies 850 Hz The higher the frequency the

shorter the wave length and better attenuation

An absorbing layer tightly adjacent to a solid structure

has nevertheless one disadvantage To attenuate

low frequencies it would be necessary to use verythick layers (for example for attenuation of 500 Hz a

thickness of about 20 cm would be necessary) Therefore

acoustic tiles can hardly attenuate low frequency noise

(frequencies lower than 100 dB such as noise from

discotheques)

Fortunately it is possible to avoid expensive acoustic

tiles with high thickness If we use a very thin layer

and place it just in the position of the displacement

maximum of a chosen frequency this chosen frequency

and its odd multiples will be attenuated Acoustic

tiles thus work as a selective frequency filter On theselective basis also other acoustic attenuators work

namely membranes oscillating plates and resonators

ACOUSTICS INSULATIONS

Isover stone wool products with a high longitudinal air-

flow resistance (up to 95 kPasm2) and uniform porosity

(93 ndash 99 ) are used as sound attenuation insulations

In suitable frequencies they can absorb up to 95 of

the sound energy (α = 095) Sound attenuation in a

construction is related to elastic properties of Isover

mineral wool insulations and their low modulus of

elasticity (they have low dynamic toughness and

therefore they are much more suitable for acoustic

purposes in comparison with foam plastics)

Sound attenuation properties of Isover products are

characterised by an absorption coefficient α which

can be found in the table for three thicknesses andsix frequencies According to a given noise spectrum

it is possible to design a sound attenuation structure

of which our material is only a part Since we provide

only insulation material we launch only absorption

coefficients Final attenuation will be dependent on

the whole designed construction (considering also

supporting construction hangers) and assembly

Isover does not design sound attenuation and thus it

is necessary to ask specialists who are able to design a

proper structure

Generally we can say that transmission loss is higher

for constructions with higher plane weight therefore

in most cases insulation with higher density has

better sound attenuation (eg slabs Orstech 65 90

110 Isover FireProtect 150) than insulation with lower

density (eg Orstech 45) Slabs can be manufacturedwith a facing ndash glass black tissue

GENERAL RULES FOR USING ISOVER INSULATIONS

Between insulated piping sufficient distances must

be kept

Valves should be placed without needing to go on theinsulated pipes when handling them

Spindle of valves should not be installed in an upward

direction to avoid water leakage into the insulation

Surfaces before insulating must be clean and dry It

is not possible to insulate wet or frostbitten surfaces

which may later cause damages of insulation or

insulated surfaces

Dirt and rust must be rubbed down from untreated

carbon steels

Smear and oils must be removed by detergents or

solvents from insulated surfaces

Stainless steel surfaces must not be cleaned by

detergents or solvents with chloride content They

may be cleaned only by stainless steel brushes

Chloride solution attacks stainless steel surface and

causes stress corrosion cracking in the material With

increasing surface temperature the danger of stress

corrosion cracking is raised

Piping and equipment from stainless steel can be

insulated only by mineral wool insulation in AS

quality Such material can have maximum content

of chloride ions of 10 mg in 1 kg of the insulation

material

It is necessary to avoid contact of metals which can

cause galvanic corrosion (Cu-Zn Fe-Al)For operating temperatures higher than 600 degC

aluminium jacketing should not be used

Self-tapping screw bold or rivet should be from the

same material as the jacketing

Surfaces with temperatures higher than 500 degC

should be insulated by more insulation layers in a

way that each layer has a different apparent density

Material with higher density insulates better under

higher temperatures than material with lower

density therefore insulation with higher density is

placed closer to the hot side Under low operating

temperatures thermal performance is almost equalSafety working principles must be kept for insulation

assembly

Isover products are packed into PE foil They must be

transported in covered vehicles under such conditions

to avoid moistening or other degradation They must

be stored in covered places

Wired mats

After the cutting of needed length the wired mat shall

be tightly wrapped on the pipe Wired matsrsquo butt jointsshould be in close contact to each other to ensure no

gaps between mats For multiple layer construction

each layer is staggered when applied Each layer must

be secured in place before the next is applied Individual

mats are bound together with a wire with minimal 07

mm thickness Alternatively wired hook or stainless

steel bands (with minimum width of 10 mm) can be

used Maximum distance between hooks is 150 mm

The decision to use multiple layers may be made for one

or more of the following reasons

to provide compensation for pipe expansion andcontraction

to reduce heat flow by staggering joints thus creating

a more thermally efficient installation

to achieve thickness in excess of manufacturersrsquo

capabilities

for retrofitting purposes

Lamella mats

Lamella mats Orstech LSP H consist of mineral wool

lamellas which have been glued to aluminium foil

reinforced with a glass fibre grid and these fibres are

predominantly perpendicular to the surface of themat Compressive strength but thermal conductivity

too are increased compared to mats with a fibre

orientation parallel to the surface (wired mats) Due

to its compressive strength resistance they have less

demands for undeconstruction (less thermal bridges)

in comparison with wired mats Temporary securing in

place is done by aluminium tapes final fixing shall be

done by a baling wire

Protective coverings

The efficiency and service of insulation is directly

dependent upon its protection from moisture entry andmechanical and chemical damage Choices of jacketing

materials are based upon the mechanical chemical

thermal and moisture conditions of the installation

as well as cost and appearance requirements The

basic function of the weather protection is to protect

the insulation from rain snow sleet wind solar

radiation atmospheric contamination and mechanical

damage With this definition in mind several service

requirements must be considered

PIPING INSULATION

For domestic hot water piping with smaller diameters

insulation pipe sections which are covered withaluminium foil are ideal Pipe sections with a facing

have a self-adhesive overlap in a longitudinal joint

to ensure perfect enclosure of a pipe section It is

recommended to secure pipe sections by an aluminium

tape or by galvanized wire transversely They are usually

knotted three times per meter more for pipe sections

with higher diameter Higher diameters should be

secured either by wire or by metal band (at least two

bands per meter)

Pipings with bigger diameters are most commonly

insulated by lamella mats Orstech LSP (stone woolinsulation) or Isover ML-3 (glass wool insulation)

eventually by wired mats Orstech DP (especially for higher

temperatures) Lamella and wired mats are also suitable

for appliances and vessels (both ends and cylindrical

parts) residential heating systems and air ducts

Internal mechanical forces ndash expansion and contraction

of the pipe or vessel must be considered because the

resulting forces are transferred to the external surface ofthe weather barrier Ability to slide elongate or contract

must be provided

External mechanical forces ndash mechanical abuse (ie

on the weather barrier and chemically attack the pipe or

vessel jacketing Elements that create corrosive issues

must be well understood and accounted for Insulation

design of coastal facilities should account for chloride

attack

Galvanic corrosion Contacts between two different

types of metal must be considered for galvanic corrosion

potential Similarly water can act as an electrolyte and

galvanic corrosion can occur because of the differentpotential of the pipe and vessel and a metal jacketing

Materials used as weather barriers for insulation

Typical metal jacketing materials bare aluminium coated

aluminium stainless steel painted steel galvanized steel

aluminium-zinc coated steel

Typical polymeric jacketing materials polyvinyl chloride

(PVC) polyvinyliedene chloride (PVDC) polyisobutylene

multiple-layer composite materials (eg polymericfoil

mesh laminates) fabrics (silicone-impregnated fibreglass)

Fittings valves

Insulation of fittings valves flanges and couplings is

the most time consuming and often expensive aspectof commercial and industrial insulation But it is crucial

to insulate also these parts properly otherwise most of

energy will be transported by these thermal bridges For

example for 200 degC medium heat loss of one uninsulated

valve corresponds to one meter of uninsulated pipe or

ten meters of uninsulated pipe

Fittings are items used to change size direction of flow

level or assembly of piping They may be of the screwed

sweat or welded types Valves are any of various devices

that regulate liquid or gas flow and they may be of the

screwed sweated flanged or welded types Flanges areprotruding rims and edges of the screwed or sweated

type used with fittings valves couplings etc And finally

mechanical couplings are devices used in assembly of

piping Screwed and flanged connections on fittings

valves couplings etc usually require oversized insulation

applications to compensate for the protrusions

Minimum spacing between pipes and

constructions

It is essential to ensure sufficient space between pipies

and between a pipe and a wall (minimally 100 mm)

Otherwise there is a great danger of creating a zone withalmost no cenvenction The result can be too high surface

temperature (needed personal protection against burn)

or possibility of condensation on cold piping Besides

mounting would have been more difficult

DUCTING INSULATION

Isover products are designed to provide high levels of

thermal acoustic and fire protection insulation in HVACductwork applications such as rectangular flat oval and

circular ductwork

The most suitable insulation materials for ducts are

felts KLIMAROL with aluminium foil facing lamella mats

Orstech LSP or Isover ML-3 wired mats Orstech DP or

slabs Orstech H with aluminium foil facing

Duct insulation mounting

Insulation is mostly fixed to the duct by welded pinsWhen using Orstech H slabs with aluminium facing all

the joints shall be sealed with aluminium tape If a steel

clamping band is used it is necessary to use thin-walled

steel L-profiles to avoid trimming of the insulation If

using Orstech slabs without aluminium facing or Orstech

DP wired mats proper jacketing shall be made (the most

suitable is metal steel jacketing)

FIRE PROTECTION OF VENTILATION DUCT

Description

It is vital to develop safe durable and reliable solutions

for ventilation systems as fire can easily spread from the

point of origin via ductwork Isover meets the highest

standards for fire protection providing excellent fire

resistance and top-rated reaction to fire performance

Rectangular ducts shall be insulated by Orstech 65 H

slabs with 40 mm thickness (60 mm for fire resistance EI

60 for a horizontal duct) circular ducts shall be insulated

by Orstech LSP PYRO lamella mats with 50 mm thickness

By these solutions fire resistances EI 15 30 45 and 60 S

have been certified to comply with EN 1366-1

Orstech system with fire resistance has been proven to

meet the requirements of all possible scenarios for fire

from the outside The scenarios can be identified by duct

orientation and duct shape (see table below) Horizontal

ducts normally serve one floor of a building Vertical

ducts normally serve between floors of a building All

scenarios have been done only with one layer Insulation

is fixed to a duct by welded pins Such solution is time

and material saving

Metal ductworkThe steel duct is constructed in sections of galvanised

steel sheet or stainless steel sheet minimum 08 mm thick

(standard duct sheeting for rectangular ducts specified

in DIN 24190 for circular ducts in DIN 24145) Maximum

duct size for which classification protocol is valid is 1250

mm (width) x 1000 mm (height) for rectangular duct or

diameter up to 1000 mm for a circular duct

At each cross joint flanges are fastened to the duct

with spot welds at 150 mm nominal centres

Use a ceramic tape gasket and fire-stopping mastic

between the flanges to seal the joints

Flanges are bolted together with an M10 steel nut

and bolt at each corner

Fasten the flanges together with steel clamps with

bolts M8 (see the figure) in quantity of 3 clamps per 1

meter of the flange length

Drop rods and hangers

Rectangular ducts are suspended by threaded rods and

channel section bearers A duct shall be hung with asuspension system which is independently fire rated

according to EN 1363-1 Certificated suspension system

MUPRO is recommended for the purpose Each steel

hanger consists of two threaded drop rods minimum

M10 and a channel section bearer 3840 mm Fasten

the bearer to the drop rods using hexagonal nuts and

washers The drop rods can be positioned either inside

the insulation material or outside If drop rods are outside

there is no need to insulate them separately The bearers

are positioned inside the insulation material

Circular ducts are suspended by MUumlPRO steel hangerswhich consist of two threaded drop rods minimum

M10 and a two-part industrial circular band The ends

of each band section are bent outwards Fasten the band

sections together and attach them to the drop rods with

hexagonal nuts and washers Place these hangers inside

the insulation The rods do not need to be protected by

insulation

When fixing them to a concrete construction use all-

steel expanding anchors to fasten the threaded rod

hangers to concrete soffits The anchors should penetrate

the concrete by at least 60 mm When fixing to a steel

supporting construction drill a hole through the steel

member allowing the drop rod to be supported by a steel

nut and washer above If a clamp type fixing is used the

clamp must be steel suitable for the purpose It should

pass around the steel member and be fastened back on

itself Clamps that rely on friction to hold them in place

are not suitable

Insulation

Rectangular ducts are insulated by Orstech 65 H slabs

(with apparent density 65 kgm3 and with one-sidedaluminium foil facing) with 40 mm thickness (60 mm

for fire resistance EI 60 for a horizontal duct) Circular

ducts are insulated by lamella mats Orstech LSP PYRO

with 50 mm thickness Insulation slabs (lamella mats)

need to be cut to fit the duct as tightly as possible the

insulation may need to be cut to fit around flanged duct

joints Install the insulation so that one slab (lamella

mat) is adjacent and tightly fitted against the other No

gaps must be present between butt joints of insulation

Insulation can be easily cut with a standard laggers knife

There is no need for adhesive on joints All the joints shall

be sealed by aluminium tape For rectangular ducts in theposition of flange the slabs are snick first 15 mm of the

thickness to avoid lifting of the slabs Butt joints should

be positioned out of flanges Fire protective insulation for

circular ducts does not require usage of a wire net mesh

on the outer side of insulation

Stud welded pins

The insulation is fixed to the duct using steel pins 27 mm

to 3 mm nominal diameter and spring steel washers

minimum 30 mm diameter The length of pin should

be equal to the insulation thickness The orientational

number of pins is 16 piecesm2 for rectangular ducts and14 piecesm2 for circular ducts

Recommended distance from duct edges and joints is

80 mm 50 mm from flanges

Wallfloor penetration

At wallfloor penetration one must insure the same fire

resistance of ventilation duct as has the fire separation

to avoid the spreading of fire from one compartment to

other via a duct This is possible by two basic principles

or their combinations - install a fire damper at the

penetration point or use insulation with fire resistancewhere the crucial thing is the fire-stopping The fire-

stopping is from the second insulation layer with the

width of 150 mm from both side of fire separation

The same general principle is used for both rectangular

and circular ducts regardless of orientation Place

the duct in the penetration of the construction with

approximately 10 mm gap between insulated duct and

opening Before installing the fire-stopping with the

same insulation thickness as is used for the first layer

pack the space between the duct and partition with

as many pieces of insulation as possible Ensure tight

compression in order to completely fill the opening This

must be done because system ORSTECH Protect does

not require stiffeners inside the duct Then install thesecond insulation layer so that it is adjacent and tightly

fitted against the penetration The insulation must be

cut leaving excess length so that it exerts some pressure

between the penetration and the last fitted piece of

insulation

The second layer is fixed by welded pins with length

equal to double insulation thickness The second layer for

circular ducts (lamella mats) is clamped with 1-2 wires

with a diameter 16 mm Then the insulation is secured

to the duct by welded pins

A inovative solution is the considerable simplification of

a fire-stopping concept There is no need to use any kind

of stiffener either inside or outside of the duct A great

advantage is to mount the whole ventilation section

at once and the wall itself can be placed anywhere

Therefore the position variability of fire separation is

provided No glue or mastic is needed at wallfloor

penetrations

Fire classification

ORSTECH Protect insulation with fire resistance has

been tested by the fire testing laboratory Pavus as an

authorised body AO 216 Classification protocols on the

request

Fire protection system ORSTECH Protect has been tested

in accordance with EN 1366-1 Maximum size for the

rectangular duct is 1250 x 1000 mm and for the circular

duct up to diameter 1000 mm If a duct has bigger

dimensions the certificate connected to the standard

cannot be used

to provide compensation for pipe expansion and

contraction

to reduce heat flow by staggering joints thus creatinga more thermally efficient installation

to achieve thickness in excess of manufacturersrsquo

capabilities

for retrofitting purposes

Insulation is usually fixed by mechanical fasteners - by

studs or pins Spacing between them is dependent on the

design of the vessel its surface temperature fire hazard

potential involved and presumptive loading Each slab

should be fixed by minimally two pins

BOILER INSULATIONInsulations for boilers kettles and ovens are one of

the most demanding applications in industry because

these units are operating at very high temperatures

Good insulation not only saves energy considerably but

the main purpose is personal protection against burn

According to the surface shape and temperature are used

either slabs with higher densities Orstech 65 to 110 (for

boilers with flat surfaces) or wired mats Orstech DP 65 to

DP 100 (for boilers with cylindrical parts)

Boiler walls are exposed to very high temperatures

(usually around 500 or 600 degC) Therefore it is essential

to use mechanical fasteners for the fixing of insulation

to the surface Insulation for boilers is done in at least

two layers each layer must be staggered when applied

Each layer must be secured in place before the next is

applied A product with high density should be placed as

the first layer because it has a higher maximum surface

temperature (higher resistance against high operating

temperatures) and better insulation performace than

products with lower densities

CHIMNEY INSULATION

Insulations for prefabricated chimneys are directly

supplied by producers of such systems In cooperation

with specialized wholesale companies we offer slabs

with multi-plate stripes which allow easy and perfect

application for prefabricated chimneys suitable both

for stainless steel chimney liners as well as with other

brands of chimney lining systems The main advantage

is the time saving during the installation in comparison

with the use of lamella mats and horizontal orientation

of fibres (better thermal conductivity) Insulation

dimensions ie thickness of slabs and groove dimensions

dependent on the chimney diameter are supplied

according to customer needs

For non-prefabricated chimneys are mostly used wired

mats Orstech DP or slabs Orstech 90 or 110 (for chimneys

with rectangular cross-section)

TECHNOLOGICAL APPLIANCEINSULATIONWhere big quantities of energy is used eg within

petrochemical paper and pulp industries thermal

insulation is necessary in order to reduce expensive

energy losses Tanks vessels exhausts exchangers

and technological piping are appliances that are often

working at high temperatures Good insulation will save

energy considerably which will benefit the environment

and keep the working costs down At the same time

the insulation will reduce temperature fall which could

disturb the production process

Proper insulation can be chosen in accordance with

dimension surface temperature the manner of fixing

and requirements for jacketing For pipes and cylindrical

parts are used lamella mats Orstech LSP H and Isover

ML-3 (only for temperatures up to 250 degC) or wired mats

Orstech DP For appliances and vessels with rectangular

shapes Orstech slabs are suitable (type according to a

surface temperature) Slabs can have aluminium facing

If insulation is done in more than one layer each layer

is staggered when applied Each layer must be secured

in place before the next is applied The decision to use

multiple layers may be made for one or more of the

following reasons

Economic thickness calculations are based on the law

of diminishing returns Because no insulation material

can completely stop the flow of heat each increment ofinsulation added to the thickness saves only a percentage

of the heat which has escaped through the underlying

insulation Therefore each increment of insulation

saves less than the one before it and must be evaluated

against the cost of installation to determine if it is a

ldquogood investmentrdquo It is possible to determine how much

insulation applied to a given system will repay its initial

costs in a specified time This point is reached when the

cost of the last incremental of insulation added is offset

by the savings generated by that increment

Refer to the stetch on the left The vertical scale is the

annual cost The horizontal scale is insulation thickness

As the insulation thickness increases from 0 the cost of

heat loss through the insulation decreases Note that this

cost (line B) tends to approach a horizontal line at high

thicknesses As the insulation thickness increases the

cost of the insulation also increases (line A) The total

annual cost at any insulation thickness is the sum of the

cost of the insulation and the cost of the lost heat (line

C) Line C goes through a minimum value of total annual

cost at the Economic thickness

With thicknesses less than the economic thickness the

total annual cost is higher because of the higher valueof the cost of lost heat With thicknesses higher than

the economic thickness the total annual cost is higher

because of the higher value of the cost of the insulation

In the case of computer results each pipe size will be

listed with the recommended thickness as well as

the average heat savings (as compared to a pre-listed

thickness or bare surface whichever chosen) and the

present value of the heat saved

In order to use any of the available manuals tables

or computer programs the two cost factors (cost of

lost energy and cost of insulation) must be found Thefollowing data is generally provided by the investor

Cost of lost energy

This factor is derived from the combination of the

rate of energy transfer the cost of energy and the

operational hours per year of the building Computing

the rate of energy transfer requires surface and

ambient temperatures thermal conductivity of the

chosen insulation the maximumminimum thickness of

insulation to be considered surface emissivity and last

but not least consideration of surface orientation (i evertical horizontal) and wind (air) velocity

Cost of insulation

This factor is derived from computing a bdquounit installed

price of insulationldquo with the total cost annualized overthe projectacutes life The unit installed price is a combination

of the cost of materials cost of labor and worker

productivity This is a sensitive variable in the economic

thickness calculation Only the roughest of regional

averages are available As a result care must be taken not

to perceive these estimates as fixed budget prices used

for installing insulation Material prices are related to the

volume and cost of the insulation jacketing securement

finishing and structural support material used Also

included in this figure are storage and handling costs to

the contractor Labor costs vary regionally and include

wages fringe benefits per diem and travel expensesas well as overhead and profit Labor production varies

with pipe size complexity number of layers necessary

accessibility of piping and surfaces type of materials

used and general working conditions Other costs

involve the job size and increase with the magnitude of

the job They include the preparation scaffolding clean-

up and tear-down costs supervision costs and general

overhead

ISOCALreg

For economic thickness calculation program IsoCal

can be used The program also handles the followingcalculations

heat loss calculation

temperature change in pipes or ducts

temperature change in a tank

internal or external condensation

frost protection of water pipes

sound attenuation in ducts

IsoCalreg is a computer program for calculations of

thermal insulation for building equipment and

industrial installations The program mainly calculates

according to EN ISO 12 241 IsoCalreg has been developedprimarily for Saint-Gobain Isoverrsquos range of insulation

products it is however possible to perform more

generic calculations For more information about the

English version 10 please contact your local Isover

representative

MAXIMUM SERVICE TEMPERATURE

MST is determined in a laboratory by testing under de-

fined conditions which are dependent upon the form

of delivery and which are laid down in EN 14 706 (for

wired or lamella mats slabs and felts) and EN 14 707(for pipe sections and segments) MST is determined

by establishing the temperature and time related de-

crease in thickness in one-sided heating For the test

the sample shall take a load of 500 Pa The sample is

heated with a transient of at least 5 Kmin The hot-

face temperature must be maintained for 72 hours at

the expected maximum service temperature At the

maximum service temperature no test result must dis-

play a deformation under load of more than 5

In data sheets of different producers (not only mineral

wool) you will often find MST and value which is not

measured accordance to EN 14 706 This temperature

is only assumed When using such temperature there

is a danger of insulation degradation mainly insulation

thickness If mineral wool product has MST 700 or 750 degC

in its data sheet you can be sure that the material will

not withstand such temperature without degradation

of assessed properties Such temperatures shall not

be used Producers should leave field of assumed MST

and test their products to be able to use declared

MST according to EN 14 706 It is an outstandingimprovement compared to the past because individual

products on the European market can be compared to

each other according to standards valid in the EU

Slabs wired and lamella mats Orstech are certificated

according to valid European standards they are

regularly tested in testing laboratory FIW Muumlnchen

according to VDI 2055 and AGI Q 132 Maximum service

temperatures for various products can be found at the

end of the catalogue in the chapter Isover Products on

page 21)

EVAPORATION OF BINDERS

Binders and greasing agents in mineral wool products

dissolve and evaporate in areas with temperatures

higher than 150 degC Binder evaporation does not have any

influence on thermal properties only the compactness

of a material is decreased If proper underconstruction

is made there is almost no danger of insulation slide

down But if too small insulation thickness or improper

type of insulation is used (mostly insulation with too

low density for too high temperatures) danger of binder

evaporation in the whole thickness is possible with

consequent insulation slide down In this case no well

made underconstruction will help Insulation will not

work any more In the outer colder areas no dissolution

and evaporation take place

FIRE PERFORMANCE

FIRE ndash a chemical reaction involving rapid oxidation or

burning of a fuel occurs only when three elements are

present in the proper conditions and proportions

FUEL ndash Fuel can be any combustible material - solid

liquid or gas Most solids and liquids become a vapour

or gas before they burn

OXYGEN ndash The air we breathe is about 21 oxygen Fire

only needs an atmosphere with at least 16 oxygen

HEAT ndash Heat is the energy necessary to increase the

temperature of the fuel to a point where sufficient

vapours are given off for ignition to occur

Fire development depends mostly on room geometry

and ventilation the fuel type the amount and surface

area of the fuel Fire is often discussed in terms of the

temperature development and can be divided into

different stages incipience (ignition) growth flashover

fully developed fire and decay

How materials behave in the early stages of a fire from

ignition to flashover (the spontaneous ignition of hot

smoke and gasses) needs to be assessed at the design

stage for buildings and also for plants and equipment

Euroclasses a new European harmonised classification

system for materialsrsquo reaction to fire in most Europeancountries replaced the old national standards The

Euroclass fire classification covers not only materials

used in building structures but it is being extended also

to technical insulations to cover building equipment

and industrial installations This will help to compare

the reaction to fire of different thermal insulation

materials

The classification levels are A1A2 (completely non-

combustible) B C D E and F A1A2 corresponds to

the safest situation E would be the most dangerous

situation and F would mean not classified

ISOVER mineral wool insulations are totally non-

combustible and completely fire safe achieving

Euroclass A1 fire rating (A2 for products with facing)when classified in accordance with EN 13501-1 One

of the most important issues studied under reaction to

fire performance is the potential for flashover to occur

which can lead to a fire spreading uncontrollably Isover

stone wool is not susceptible to flashover

REACTION TO FIRE

Smoke and flaming droplet risk(1) In the EU classification system for reaction to fire

a construction product will be classified as Euroclass A1

A2 B C D E or F depending on its tendency to burn

(2) The product testing will provide data represented

by the signs s1 s2 or s3 which indicate the tendency

to release smoke Smoke causes over 60 of deaths in

fire across the EU The measurement of smoke release

has been put into these 3 broad bands that can be

translated as ldquolittle or no smokerdquo s1 - rdquoquite a lot of

smokerdquo s2 - rdquosubstantial smoke releaserdquo s3

(3) Some construction products like these made of

polystyrene can melt and ignite to form Flaming

Droplets Wooden products on the other hand will tend

to char before the char falls away as Flaming Particles

to expose more material

These rdquoflaming dropletsparticlesrdquo will tend to

initiate new fires away from the original point of

ignition and must be considered when the products

are used horizontally in ceiling or roof applications

The classification system ranks the level of release of

flaming dropletsparticles as d0 (none) d1 (some) and

d2 (quite a lot)

FIRE PROTECTION DESIGN FOR VENTILATION DUCTS

Produced with the stone wool technology of Isover

fire protection system ORSTECH Protect is mineral

wool that combines all the advantages of conventionalthermal and acoustic insulation with top level of fire

safety Mineral wool insulations have the melting point

higher than 1000 degC From the fire protection point of

view products Isover are one of the safest materials

ORSTECH Protect consists of slab or lamella mat

solutions offering up to one hour fire protection for

both vertical and horizontal applications of rectangular

and circular ductwork systems

Passive protection of ventilation ducts is possible by

two basic means

Installed a fire damper into the duct to the place of

fire separation

Use a fire protection insulation system which is

tested according EN 1366-1 and has a classification

protocol in accordance with EN 13 501-3 This second

case is covered by insulation system ORSTECH

Protect

LEGISLATION

Air duct which shall resist the spread of fire from one

compartment to another is tested according to EN

1366-1 The standard can be applied to vertical and

horizontal ducts with or without branches for fire inside

or outside the duct The test measures the time period

for which ducts of specified dimensions suspended as

they would be in practice satisfy criteria when exposed

to fire from inside or outside (separately)

This standard is used in conjunction with EN 1363-1

which prescribes requirements for the determinationof fire resistance of various components of building

structures which are exposed to standard fire

conditions In this standard there are failure criteria

whereby it is possible to evaluate the ability of a tested

duct to prevent fire spread due to the destruction of

the duct (integrity failure E) heat transfer (insulationfailure I) and prevention of the smoke penetration

(smoke leakage S) Fire protection is expressed by time

in minutes for which failure criteria are fulfilled

Designation itself is then done according to

classification standard EN 13 501-3 Classification

states if criteria are fulfilled for fire outside (marking

o rarr i) valid for duct type A or fire inside (marking

irarr o) or from both directions (iharr o) valid for duct type

B and if this is valid for a horizontal duct (marking ho)

or a vertical one (ve) or both (ve ho) Eg class bdquoEI 30 S

ndash ve ho (orarr i) Sldquo represents duct capability to maintain

integrity insulation and smoke leakage for time period

of 30 minutes under fire exposure from outside both

for vertical and horizontal positions

MAXIMUM DUCT SIZES

Maximum size is according to EN 1366-1 for rectangular

duct 1250 x 1000 mm and for circular duct up to

diameter 1000 mm If a duct has bigger dimensions the

classification protocol cannot be used

ACOUSTIC PERFORMANCE

Noise is a sound which impacts negatively on the

surroundings Noise levels emanating from HVAC

services (pipework ductwork and air handlingequipment) and other services can be significantly

reduced with the use of Isover products which will

help to achieve acceptable environmental noise levels

Isover insulations are due to its fibre structure an ideal

material for sound attenuation not only for industrial

application The degree of sound insulation will depend

upon the application the thickness of insulation used

and the nature of any finish used to clad over the

installation In suitable frequencies they can absorb up

to 95 of the sound energy (α = 095)

SOUND ABSORPTIONWhen a sound wave strikes a surface the sound energy

is broken down into transmitted energy (through the

material) converted energy (usually heat) and reflected

energy (back towards the source of the sound)

The more absorbent the material the less sound is

reflected That part of sound energy which is converted

and transmitted is usually expressed as an absorption

coefficient α

The absorption coefficient for a material varies with

the frequency An absorbent layer of mineral wool

has the best absorption capacity in medium and high

frequencies The absorption in low frequencies is

improved by increasing the thickness or by providing an

air gap behind the absorbent layer

Examples of the effectiveness of Isover products in noise

control are given in the following table

ABSORPTIVE STRUCTURES

The most common task in room acoustics is to attenuate

or cancel some frequencies or a whole frequency band

This is possible to realise by using convenient absorptive

material or structures which are frequency-dependent

In this way we can control not only absorption ie

reverberation time but also suppress or completely

remove unpleasant sounds

In a porous material acoustic absorption is mainlycaused by friction in pores ie friction between

oscillating particles and the surface of pores Since the

energy loss due to friction is proportional to the length

of the path the most absorption will occur when the

porous material is placed in a position where the particle

displacement is the largest (maxima displacement)

When sound strikes a rigid wall like concrete for

example a standing wave result and the maxima of

particle displacement appear at the distances λ14

3λ24 5λ

34 hellip from the surface of a room These are the

critical distances which must be covered by adsorbers

ie layers with thicknesses d1 = λ

14 d

2 = 3λ

24 d

3 = 5λ

34

In short an absorber with a thickeness d placed directly

on the solid structure will effectively attenuate only

those frequencies where f ge c4d (c is the velocity of

sound 340 ms) For example insulation thickness

of 50 mm wil l reliably attenuate frequencies higher

than 1700 Hz thickness 100 mm then already from

frequencies 850 Hz The higher the frequency the

shorter the wave length and better attenuation

An absorbing layer tightly adjacent to a solid structure

has nevertheless one disadvantage To attenuate

low frequencies it would be necessary to use verythick layers (for example for attenuation of 500 Hz a

thickness of about 20 cm would be necessary) Therefore

acoustic tiles can hardly attenuate low frequency noise

(frequencies lower than 100 dB such as noise from

discotheques)

Fortunately it is possible to avoid expensive acoustic

tiles with high thickness If we use a very thin layer

and place it just in the position of the displacement

maximum of a chosen frequency this chosen frequency

and its odd multiples will be attenuated Acoustic

tiles thus work as a selective frequency filter On theselective basis also other acoustic attenuators work

namely membranes oscillating plates and resonators

ACOUSTICS INSULATIONS

Isover stone wool products with a high longitudinal air-

flow resistance (up to 95 kPasm2) and uniform porosity

(93 ndash 99 ) are used as sound attenuation insulations

In suitable frequencies they can absorb up to 95 of

the sound energy (α = 095) Sound attenuation in a

construction is related to elastic properties of Isover

mineral wool insulations and their low modulus of

elasticity (they have low dynamic toughness and

therefore they are much more suitable for acoustic

purposes in comparison with foam plastics)

Sound attenuation properties of Isover products are

characterised by an absorption coefficient α which

can be found in the table for three thicknesses andsix frequencies According to a given noise spectrum

it is possible to design a sound attenuation structure

of which our material is only a part Since we provide

only insulation material we launch only absorption

coefficients Final attenuation will be dependent on

the whole designed construction (considering also

supporting construction hangers) and assembly

Isover does not design sound attenuation and thus it

is necessary to ask specialists who are able to design a

proper structure

Generally we can say that transmission loss is higher

for constructions with higher plane weight therefore

in most cases insulation with higher density has

better sound attenuation (eg slabs Orstech 65 90

110 Isover FireProtect 150) than insulation with lower

density (eg Orstech 45) Slabs can be manufacturedwith a facing ndash glass black tissue

GENERAL RULES FOR USING ISOVER INSULATIONS

Between insulated piping sufficient distances must

be kept

Valves should be placed without needing to go on theinsulated pipes when handling them

Spindle of valves should not be installed in an upward

direction to avoid water leakage into the insulation

Surfaces before insulating must be clean and dry It

is not possible to insulate wet or frostbitten surfaces

which may later cause damages of insulation or

insulated surfaces

Dirt and rust must be rubbed down from untreated

carbon steels

Smear and oils must be removed by detergents or

solvents from insulated surfaces

Stainless steel surfaces must not be cleaned by

detergents or solvents with chloride content They

may be cleaned only by stainless steel brushes

Chloride solution attacks stainless steel surface and

causes stress corrosion cracking in the material With

increasing surface temperature the danger of stress

corrosion cracking is raised

Piping and equipment from stainless steel can be

insulated only by mineral wool insulation in AS

quality Such material can have maximum content

of chloride ions of 10 mg in 1 kg of the insulation

material

It is necessary to avoid contact of metals which can

cause galvanic corrosion (Cu-Zn Fe-Al)For operating temperatures higher than 600 degC

aluminium jacketing should not be used

Self-tapping screw bold or rivet should be from the

same material as the jacketing

Surfaces with temperatures higher than 500 degC

should be insulated by more insulation layers in a

way that each layer has a different apparent density

Material with higher density insulates better under

higher temperatures than material with lower

density therefore insulation with higher density is

placed closer to the hot side Under low operating

temperatures thermal performance is almost equalSafety working principles must be kept for insulation

assembly

Isover products are packed into PE foil They must be

transported in covered vehicles under such conditions

to avoid moistening or other degradation They must

be stored in covered places

Wired mats

After the cutting of needed length the wired mat shall

be tightly wrapped on the pipe Wired matsrsquo butt jointsshould be in close contact to each other to ensure no

gaps between mats For multiple layer construction

each layer is staggered when applied Each layer must

be secured in place before the next is applied Individual

mats are bound together with a wire with minimal 07

mm thickness Alternatively wired hook or stainless

steel bands (with minimum width of 10 mm) can be

used Maximum distance between hooks is 150 mm

The decision to use multiple layers may be made for one

or more of the following reasons

to provide compensation for pipe expansion andcontraction

to reduce heat flow by staggering joints thus creating

a more thermally efficient installation

to achieve thickness in excess of manufacturersrsquo

capabilities

for retrofitting purposes

Lamella mats

Lamella mats Orstech LSP H consist of mineral wool

lamellas which have been glued to aluminium foil

reinforced with a glass fibre grid and these fibres are

predominantly perpendicular to the surface of themat Compressive strength but thermal conductivity

too are increased compared to mats with a fibre

orientation parallel to the surface (wired mats) Due

to its compressive strength resistance they have less

demands for undeconstruction (less thermal bridges)

in comparison with wired mats Temporary securing in

place is done by aluminium tapes final fixing shall be

done by a baling wire

Protective coverings

The efficiency and service of insulation is directly

dependent upon its protection from moisture entry andmechanical and chemical damage Choices of jacketing

materials are based upon the mechanical chemical

thermal and moisture conditions of the installation

as well as cost and appearance requirements The

basic function of the weather protection is to protect

the insulation from rain snow sleet wind solar

radiation atmospheric contamination and mechanical

damage With this definition in mind several service

requirements must be considered

PIPING INSULATION

For domestic hot water piping with smaller diameters

insulation pipe sections which are covered withaluminium foil are ideal Pipe sections with a facing

have a self-adhesive overlap in a longitudinal joint

to ensure perfect enclosure of a pipe section It is

recommended to secure pipe sections by an aluminium

tape or by galvanized wire transversely They are usually

knotted three times per meter more for pipe sections

with higher diameter Higher diameters should be

secured either by wire or by metal band (at least two

bands per meter)

Pipings with bigger diameters are most commonly

insulated by lamella mats Orstech LSP (stone woolinsulation) or Isover ML-3 (glass wool insulation)

eventually by wired mats Orstech DP (especially for higher

temperatures) Lamella and wired mats are also suitable

for appliances and vessels (both ends and cylindrical

parts) residential heating systems and air ducts

Internal mechanical forces ndash expansion and contraction

of the pipe or vessel must be considered because the

resulting forces are transferred to the external surface ofthe weather barrier Ability to slide elongate or contract

must be provided

External mechanical forces ndash mechanical abuse (ie

tools being dropped abrasion from wind-driven sand

personnel walking on the system) inflicted on a pipe or

vessel needs to be considered in design This may affect

insulation type as well as the weather barrier jacketing

type

Chemical resistance Some industrial environments may

have airborne or spilled corrosive agents that accumulate

on the weather barrier and chemically attack the pipe or

vessel jacketing Elements that create corrosive issues

must be well understood and accounted for Insulation

design of coastal facilities should account for chloride

attack

Galvanic corrosion Contacts between two different

types of metal must be considered for galvanic corrosion

potential Similarly water can act as an electrolyte and

galvanic corrosion can occur because of the differentpotential of the pipe and vessel and a metal jacketing

Materials used as weather barriers for insulation

Typical metal jacketing materials bare aluminium coated

aluminium stainless steel painted steel galvanized steel

aluminium-zinc coated steel

Typical polymeric jacketing materials polyvinyl chloride

(PVC) polyvinyliedene chloride (PVDC) polyisobutylene

multiple-layer composite materials (eg polymericfoil

mesh laminates) fabrics (silicone-impregnated fibreglass)

Fittings valves

Insulation of fittings valves flanges and couplings is

the most time consuming and often expensive aspectof commercial and industrial insulation But it is crucial

to insulate also these parts properly otherwise most of

energy will be transported by these thermal bridges For

example for 200 degC medium heat loss of one uninsulated

valve corresponds to one meter of uninsulated pipe or

ten meters of uninsulated pipe

Fittings are items used to change size direction of flow

level or assembly of piping They may be of the screwed

sweat or welded types Valves are any of various devices

that regulate liquid or gas flow and they may be of the

screwed sweated flanged or welded types Flanges areprotruding rims and edges of the screwed or sweated

type used with fittings valves couplings etc And finally

mechanical couplings are devices used in assembly of

piping Screwed and flanged connections on fittings

valves couplings etc usually require oversized insulation

applications to compensate for the protrusions

Minimum spacing between pipes and

constructions

It is essential to ensure sufficient space between pipies

and between a pipe and a wall (minimally 100 mm)

Otherwise there is a great danger of creating a zone withalmost no cenvenction The result can be too high surface

temperature (needed personal protection against burn)

or possibility of condensation on cold piping Besides

mounting would have been more difficult

DUCTING INSULATION

Isover products are designed to provide high levels of

thermal acoustic and fire protection insulation in HVACductwork applications such as rectangular flat oval and

circular ductwork

The most suitable insulation materials for ducts are

felts KLIMAROL with aluminium foil facing lamella mats

Orstech LSP or Isover ML-3 wired mats Orstech DP or

slabs Orstech H with aluminium foil facing

Duct insulation mounting

Insulation is mostly fixed to the duct by welded pinsWhen using Orstech H slabs with aluminium facing all

the joints shall be sealed with aluminium tape If a steel

clamping band is used it is necessary to use thin-walled

steel L-profiles to avoid trimming of the insulation If

using Orstech slabs without aluminium facing or Orstech

FIRE PROTECTION OF VENTILATION DUCT

Description

It is vital to develop safe durable and reliable solutions

for ventilation systems as fire can easily spread from the

point of origin via ductwork Isover meets the highest

standards for fire protection providing excellent fire

resistance and top-rated reaction to fire performance

Rectangular ducts shall be insulated by Orstech 65 H

slabs with 40 mm thickness (60 mm for fire resistance EI

60 for a horizontal duct) circular ducts shall be insulated

by Orstech LSP PYRO lamella mats with 50 mm thickness

By these solutions fire resistances EI 15 30 45 and 60 S

have been certified to comply with EN 1366-1

Orstech system with fire resistance has been proven to

meet the requirements of all possible scenarios for fire

from the outside The scenarios can be identified by duct

orientation and duct shape (see table below) Horizontal

ducts normally serve one floor of a building Vertical

ducts normally serve between floors of a building All

scenarios have been done only with one layer Insulation

is fixed to a duct by welded pins Such solution is time

and material saving

Metal ductworkThe steel duct is constructed in sections of galvanised

steel sheet or stainless steel sheet minimum 08 mm thick

(standard duct sheeting for rectangular ducts specified

in DIN 24190 for circular ducts in DIN 24145) Maximum

duct size for which classification protocol is valid is 1250

mm (width) x 1000 mm (height) for rectangular duct or

diameter up to 1000 mm for a circular duct

At each cross joint flanges are fastened to the duct

with spot welds at 150 mm nominal centres

Use a ceramic tape gasket and fire-stopping mastic

between the flanges to seal the joints

Flanges are bolted together with an M10 steel nut

and bolt at each corner

Fasten the flanges together with steel clamps with

bolts M8 (see the figure) in quantity of 3 clamps per 1

meter of the flange length

Drop rods and hangers

Rectangular ducts are suspended by threaded rods and

channel section bearers A duct shall be hung with asuspension system which is independently fire rated

according to EN 1363-1 Certificated suspension system

MUPRO is recommended for the purpose Each steel

hanger consists of two threaded drop rods minimum

M10 and a channel section bearer 3840 mm Fasten

the bearer to the drop rods using hexagonal nuts and

washers The drop rods can be positioned either inside

the insulation material or outside If drop rods are outside

there is no need to insulate them separately The bearers

are positioned inside the insulation material

Circular ducts are suspended by MUumlPRO steel hangerswhich consist of two threaded drop rods minimum

M10 and a two-part industrial circular band The ends

of each band section are bent outwards Fasten the band

sections together and attach them to the drop rods with

hexagonal nuts and washers Place these hangers inside

the insulation The rods do not need to be protected by

insulation

When fixing them to a concrete construction use all-

steel expanding anchors to fasten the threaded rod

hangers to concrete soffits The anchors should penetrate

the concrete by at least 60 mm When fixing to a steel

supporting construction drill a hole through the steel

member allowing the drop rod to be supported by a steel

nut and washer above If a clamp type fixing is used the

clamp must be steel suitable for the purpose It should

pass around the steel member and be fastened back on

itself Clamps that rely on friction to hold them in place

are not suitable

Insulation

Rectangular ducts are insulated by Orstech 65 H slabs

(with apparent density 65 kgm3 and with one-sidedaluminium foil facing) with 40 mm thickness (60 mm

for fire resistance EI 60 for a horizontal duct) Circular

ducts are insulated by lamella mats Orstech LSP PYRO

with 50 mm thickness Insulation slabs (lamella mats)

need to be cut to fit the duct as tightly as possible the

insulation may need to be cut to fit around flanged duct

joints Install the insulation so that one slab (lamella

mat) is adjacent and tightly fitted against the other No

gaps must be present between butt joints of insulation

Insulation can be easily cut with a standard laggers knife

There is no need for adhesive on joints All the joints shall

be sealed by aluminium tape For rectangular ducts in theposition of flange the slabs are snick first 15 mm of the

thickness to avoid lifting of the slabs Butt joints should

be positioned out of flanges Fire protective insulation for

circular ducts does not require usage of a wire net mesh

on the outer side of insulation

Stud welded pins

The insulation is fixed to the duct using steel pins 27 mm

to 3 mm nominal diameter and spring steel washers

minimum 30 mm diameter The length of pin should

be equal to the insulation thickness The orientational

number of pins is 16 piecesm2 for rectangular ducts and14 piecesm2 for circular ducts

Recommended distance from duct edges and joints is

At wallfloor penetration one must insure the same fire

resistance of ventilation duct as has the fire separation

to avoid the spreading of fire from one compartment to

other via a duct This is possible by two basic principles

or their combinations - install a fire damper at the

penetration point or use insulation with fire resistancewhere the crucial thing is the fire-stopping The fire-

stopping is from the second insulation layer with the

width of 150 mm from both side of fire separation

The same general principle is used for both rectangular

and circular ducts regardless of orientation Place

the duct in the penetration of the construction with

approximately 10 mm gap between insulated duct and

opening Before installing the fire-stopping with the

same insulation thickness as is used for the first layer

pack the space between the duct and partition with

as many pieces of insulation as possible Ensure tight

compression in order to completely fill the opening This

must be done because system ORSTECH Protect does

not require stiffeners inside the duct Then install thesecond insulation layer so that it is adjacent and tightly

fitted against the penetration The insulation must be

cut leaving excess length so that it exerts some pressure

between the penetration and the last fitted piece of

insulation

The second layer is fixed by welded pins with length

equal to double insulation thickness The second layer for

circular ducts (lamella mats) is clamped with 1-2 wires

with a diameter 16 mm Then the insulation is secured

to the duct by welded pins

A inovative solution is the considerable simplification of

a fire-stopping concept There is no need to use any kind

of stiffener either inside or outside of the duct A great

advantage is to mount the whole ventilation section

at once and the wall itself can be placed anywhere

Therefore the position variability of fire separation is

provided No glue or mastic is needed at wallfloor

penetrations

Fire classification

ORSTECH Protect insulation with fire resistance has

been tested by the fire testing laboratory Pavus as an

authorised body AO 216 Classification protocols on the

request

Fire protection system ORSTECH Protect has been tested

in accordance with EN 1366-1 Maximum size for the

rectangular duct is 1250 x 1000 mm and for the circular

duct up to diameter 1000 mm If a duct has bigger

dimensions the certificate connected to the standard

cannot be used

to provide compensation for pipe expansion and

contraction

to reduce heat flow by staggering joints thus creatinga more thermally efficient installation

to achieve thickness in excess of manufacturersrsquo

capabilities

for retrofitting purposes

Insulation is usually fixed by mechanical fasteners - by

studs or pins Spacing between them is dependent on the

design of the vessel its surface temperature fire hazard

potential involved and presumptive loading Each slab

should be fixed by minimally two pins

BOILER INSULATIONInsulations for boilers kettles and ovens are one of

the most demanding applications in industry because

these units are operating at very high temperatures

Good insulation not only saves energy considerably but

the main purpose is personal protection against burn

According to the surface shape and temperature are used

either slabs with higher densities Orstech 65 to 110 (for

boilers with flat surfaces) or wired mats Orstech DP 65 to

DP 100 (for boilers with cylindrical parts)

Boiler walls are exposed to very high temperatures

(usually around 500 or 600 degC) Therefore it is essential

to use mechanical fasteners for the fixing of insulation

to the surface Insulation for boilers is done in at least

two layers each layer must be staggered when applied

Each layer must be secured in place before the next is

applied A product with high density should be placed as

the first layer because it has a higher maximum surface

temperature (higher resistance against high operating

temperatures) and better insulation performace than

products with lower densities

CHIMNEY INSULATION

Insulations for prefabricated chimneys are directly

supplied by producers of such systems In cooperation

with specialized wholesale companies we offer slabs

with multi-plate stripes which allow easy and perfect

application for prefabricated chimneys suitable both

for stainless steel chimney liners as well as with other

brands of chimney lining systems The main advantage

is the time saving during the installation in comparison

with the use of lamella mats and horizontal orientation

of fibres (better thermal conductivity) Insulation

dimensions ie thickness of slabs and groove dimensions

dependent on the chimney diameter are supplied

according to customer needs

For non-prefabricated chimneys are mostly used wired

mats Orstech DP or slabs Orstech 90 or 110 (for chimneys

with rectangular cross-section)

TECHNOLOGICAL APPLIANCEINSULATIONWhere big quantities of energy is used eg within

petrochemical paper and pulp industries thermal

insulation is necessary in order to reduce expensive

energy losses Tanks vessels exhausts exchangers

and technological piping are appliances that are often

working at high temperatures Good insulation will save

energy considerably which will benefit the environment

and keep the working costs down At the same time

the insulation will reduce temperature fall which could

disturb the production process

Proper insulation can be chosen in accordance with

dimension surface temperature the manner of fixing

and requirements for jacketing For pipes and cylindrical

parts are used lamella mats Orstech LSP H and Isover

ML-3 (only for temperatures up to 250 degC) or wired mats

Orstech DP For appliances and vessels with rectangular

shapes Orstech slabs are suitable (type according to a

surface temperature) Slabs can have aluminium facing

If insulation is done in more than one layer each layer

is staggered when applied Each layer must be secured

in place before the next is applied The decision to use

multiple layers may be made for one or more of the

following reasons

MAXIMUM SERVICE TEMPERATURE

MST is determined in a laboratory by testing under de-

fined conditions which are dependent upon the form

of delivery and which are laid down in EN 14 706 (for

wired or lamella mats slabs and felts) and EN 14 707(for pipe sections and segments) MST is determined

by establishing the temperature and time related de-

crease in thickness in one-sided heating For the test

the sample shall take a load of 500 Pa The sample is

heated with a transient of at least 5 Kmin The hot-

face temperature must be maintained for 72 hours at

the expected maximum service temperature At the

maximum service temperature no test result must dis-

play a deformation under load of more than 5

In data sheets of different producers (not only mineral

wool) you will often find MST and value which is not

measured accordance to EN 14 706 This temperature

is only assumed When using such temperature there

is a danger of insulation degradation mainly insulation

thickness If mineral wool product has MST 700 or 750 degC

in its data sheet you can be sure that the material will

not withstand such temperature without degradation

of assessed properties Such temperatures shall not

be used Producers should leave field of assumed MST

and test their products to be able to use declared

MST according to EN 14 706 It is an outstandingimprovement compared to the past because individual

products on the European market can be compared to

each other according to standards valid in the EU

Slabs wired and lamella mats Orstech are certificated

according to valid European standards they are

regularly tested in testing laboratory FIW Muumlnchen

according to VDI 2055 and AGI Q 132 Maximum service

temperatures for various products can be found at the

end of the catalogue in the chapter Isover Products on

page 21)

EVAPORATION OF BINDERS

Binders and greasing agents in mineral wool products

dissolve and evaporate in areas with temperatures

higher than 150 degC Binder evaporation does not have any

influence on thermal properties only the compactness

of a material is decreased If proper underconstruction

is made there is almost no danger of insulation slide

down But if too small insulation thickness or improper

type of insulation is used (mostly insulation with too

low density for too high temperatures) danger of binder

evaporation in the whole thickness is possible with

consequent insulation slide down In this case no well

made underconstruction will help Insulation will not

work any more In the outer colder areas no dissolution

and evaporation take place

FIRE PERFORMANCE

FIRE ndash a chemical reaction involving rapid oxidation or

burning of a fuel occurs only when three elements are

present in the proper conditions and proportions

FUEL ndash Fuel can be any combustible material - solid

liquid or gas Most solids and liquids become a vapour

or gas before they burn

OXYGEN ndash The air we breathe is about 21 oxygen Fire

only needs an atmosphere with at least 16 oxygen

HEAT ndash Heat is the energy necessary to increase the

temperature of the fuel to a point where sufficient

vapours are given off for ignition to occur

Fire development depends mostly on room geometry

and ventilation the fuel type the amount and surface

area of the fuel Fire is often discussed in terms of the

temperature development and can be divided into

different stages incipience (ignition) growth flashover

fully developed fire and decay

How materials behave in the early stages of a fire from

ignition to flashover (the spontaneous ignition of hot

smoke and gasses) needs to be assessed at the design

stage for buildings and also for plants and equipment

Euroclasses a new European harmonised classification

system for materialsrsquo reaction to fire in most Europeancountries replaced the old national standards The

Euroclass fire classification covers not only materials

used in building structures but it is being extended also

to technical insulations to cover building equipment

and industrial installations This will help to compare

the reaction to fire of different thermal insulation

materials

The classification levels are A1A2 (completely non-

combustible) B C D E and F A1A2 corresponds to

the safest situation E would be the most dangerous

situation and F would mean not classified

ISOVER mineral wool insulations are totally non-

combustible and completely fire safe achieving

Euroclass A1 fire rating (A2 for products with facing)when classified in accordance with EN 13501-1 One

of the most important issues studied under reaction to

fire performance is the potential for flashover to occur

which can lead to a fire spreading uncontrollably Isover

stone wool is not susceptible to flashover

This is a guide to common building materials and their

likely Euroclassification

Check with individual product manufactures for spedific

product specifications

REACTION TO FIRE

Smoke and flaming droplet risk(1) In the EU classification system for reaction to fire

a construction product will be classified as Euroclass A1

A2 B C D E or F depending on its tendency to burn

(2) The product testing will provide data represented

by the signs s1 s2 or s3 which indicate the tendency

to release smoke Smoke causes over 60 of deaths in

fire across the EU The measurement of smoke release

has been put into these 3 broad bands that can be

translated as ldquolittle or no smokerdquo s1 - rdquoquite a lot of

smokerdquo s2 - rdquosubstantial smoke releaserdquo s3

(3) Some construction products like these made of

polystyrene can melt and ignite to form Flaming

Droplets Wooden products on the other hand will tend

to char before the char falls away as Flaming Particles

to expose more material

These rdquoflaming dropletsparticlesrdquo will tend to

initiate new fires away from the original point of

ignition and must be considered when the products

are used horizontally in ceiling or roof applications

The classification system ranks the level of release of

flaming dropletsparticles as d0 (none) d1 (some) and

d2 (quite a lot)

FIRE PROTECTION DESIGN FOR VENTILATION DUCTS

Produced with the stone wool technology of Isover

fire protection system ORSTECH Protect is mineral

wool that combines all the advantages of conventionalthermal and acoustic insulation with top level of fire

safety Mineral wool insulations have the melting point

higher than 1000 degC From the fire protection point of

view products Isover are one of the safest materials

ORSTECH Protect consists of slab or lamella mat

solutions offering up to one hour fire protection for

both vertical and horizontal applications of rectangular

and circular ductwork systems

Passive protection of ventilation ducts is possible by

two basic means

Installed a fire damper into the duct to the place of

fire separation

Use a fire protection insulation system which is

tested according EN 1366-1 and has a classification

protocol in accordance with EN 13 501-3 This second

case is covered by insulation system ORSTECH

Protect

LEGISLATION

Air duct which shall resist the spread of fire from one

compartment to another is tested according to EN

1366-1 The standard can be applied to vertical and

horizontal ducts with or without branches for fire inside

or outside the duct The test measures the time period

for which ducts of specified dimensions suspended as

they would be in practice satisfy criteria when exposed

to fire from inside or outside (separately)

This standard is used in conjunction with EN 1363-1

which prescribes requirements for the determinationof fire resistance of various components of building

structures which are exposed to standard fire

conditions In this standard there are failure criteria

whereby it is possible to evaluate the ability of a tested

duct to prevent fire spread due to the destruction of

the duct (integrity failure E) heat transfer (insulationfailure I) and prevention of the smoke penetration

(smoke leakage S) Fire protection is expressed by time

in minutes for which failure criteria are fulfilled

Designation itself is then done according to

classification standard EN 13 501-3 Classification

states if criteria are fulfilled for fire outside (marking

o rarr i) valid for duct type A or fire inside (marking

irarr o) or from both directions (iharr o) valid for duct type

B and if this is valid for a horizontal duct (marking ho)

or a vertical one (ve) or both (ve ho) Eg class bdquoEI 30 S

ndash ve ho (orarr i) Sldquo represents duct capability to maintain

integrity insulation and smoke leakage for time period

of 30 minutes under fire exposure from outside both

for vertical and horizontal positions

MAXIMUM DUCT SIZES

Maximum size is according to EN 1366-1 for rectangular

duct 1250 x 1000 mm and for circular duct up to

diameter 1000 mm If a duct has bigger dimensions the

classification protocol cannot be used

ACOUSTIC PERFORMANCE

Noise is a sound which impacts negatively on the

surroundings Noise levels emanating from HVAC

services (pipework ductwork and air handlingequipment) and other services can be significantly

reduced with the use of Isover products which will

help to achieve acceptable environmental noise levels

Isover insulations are due to its fibre structure an ideal

material for sound attenuation not only for industrial

application The degree of sound insulation will depend

upon the application the thickness of insulation used

and the nature of any finish used to clad over the

installation In suitable frequencies they can absorb up

to 95 of the sound energy (α = 095)

SOUND ABSORPTIONWhen a sound wave strikes a surface the sound energy

is broken down into transmitted energy (through the

material) converted energy (usually heat) and reflected

energy (back towards the source of the sound)

The more absorbent the material the less sound is

reflected That part of sound energy which is converted

and transmitted is usually expressed as an absorption

coefficient α

The absorption coefficient for a material varies with

the frequency An absorbent layer of mineral wool

has the best absorption capacity in medium and high

frequencies The absorption in low frequencies is

improved by increasing the thickness or by providing an

air gap behind the absorbent layer

Examples of the effectiveness of Isover products in noise

control are given in the following table

ABSORPTIVE STRUCTURES

The most common task in room acoustics is to attenuate

or cancel some frequencies or a whole frequency band

This is possible to realise by using convenient absorptive

material or structures which are frequency-dependent

In this way we can control not only absorption ie

reverberation time but also suppress or completely

remove unpleasant sounds

In a porous material acoustic absorption is mainlycaused by friction in pores ie friction between

oscillating particles and the surface of pores Since the

energy loss due to friction is proportional to the length

of the path the most absorption will occur when the

porous material is placed in a position where the particle

displacement is the largest (maxima displacement)

When sound strikes a rigid wall like concrete for

example a standing wave result and the maxima of

particle displacement appear at the distances λ14

3λ24 5λ

34 hellip from the surface of a room These are the

critical distances which must be covered by adsorbers

ie layers with thicknesses d1 = λ

14 d

2 = 3λ

24 d

3 = 5λ

34

In short an absorber with a thickeness d placed directly

on the solid structure will effectively attenuate only

those frequencies where f ge c4d (c is the velocity of

sound 340 ms) For example insulation thickness

of 50 mm wil l reliably attenuate frequencies higher

than 1700 Hz thickness 100 mm then already from

frequencies 850 Hz The higher the frequency the

shorter the wave length and better attenuation

An absorbing layer tightly adjacent to a solid structure

has nevertheless one disadvantage To attenuate

low frequencies it would be necessary to use verythick layers (for example for attenuation of 500 Hz a

thickness of about 20 cm would be necessary) Therefore

acoustic tiles can hardly attenuate low frequency noise

(frequencies lower than 100 dB such as noise from

discotheques)

Fortunately it is possible to avoid expensive acoustic

tiles with high thickness If we use a very thin layer

and place it just in the position of the displacement

maximum of a chosen frequency this chosen frequency

and its odd multiples will be attenuated Acoustic

tiles thus work as a selective frequency filter On theselective basis also other acoustic attenuators work

namely membranes oscillating plates and resonators

ACOUSTICS INSULATIONS

Isover stone wool products with a high longitudinal air-

flow resistance (up to 95 kPasm2) and uniform porosity

(93 ndash 99 ) are used as sound attenuation insulations

In suitable frequencies they can absorb up to 95 of

the sound energy (α = 095) Sound attenuation in a

construction is related to elastic properties of Isover

mineral wool insulations and their low modulus of

elasticity (they have low dynamic toughness and

therefore they are much more suitable for acoustic

purposes in comparison with foam plastics)

Sound attenuation properties of Isover products are

characterised by an absorption coefficient α which

can be found in the table for three thicknesses andsix frequencies According to a given noise spectrum

it is possible to design a sound attenuation structure

of which our material is only a part Since we provide

only insulation material we launch only absorption

coefficients Final attenuation will be dependent on

the whole designed construction (considering also

supporting construction hangers) and assembly

Isover does not design sound attenuation and thus it

is necessary to ask specialists who are able to design a

proper structure

Generally we can say that transmission loss is higher

for constructions with higher plane weight therefore

in most cases insulation with higher density has

better sound attenuation (eg slabs Orstech 65 90

110 Isover FireProtect 150) than insulation with lower

density (eg Orstech 45) Slabs can be manufacturedwith a facing ndash glass black tissue

GENERAL RULES FOR USING ISOVER INSULATIONS

Between insulated piping sufficient distances must

be kept

Valves should be placed without needing to go on theinsulated pipes when handling them

Spindle of valves should not be installed in an upward

direction to avoid water leakage into the insulation

Surfaces before insulating must be clean and dry It

is not possible to insulate wet or frostbitten surfaces

which may later cause damages of insulation or

insulated surfaces

Dirt and rust must be rubbed down from untreated

carbon steels

Smear and oils must be removed by detergents or

solvents from insulated surfaces

Stainless steel surfaces must not be cleaned by

detergents or solvents with chloride content They

may be cleaned only by stainless steel brushes

Chloride solution attacks stainless steel surface and

causes stress corrosion cracking in the material With

increasing surface temperature the danger of stress

corrosion cracking is raised

Piping and equipment from stainless steel can be

insulated only by mineral wool insulation in AS

quality Such material can have maximum content

of chloride ions of 10 mg in 1 kg of the insulation

material

It is necessary to avoid contact of metals which can

cause galvanic corrosion (Cu-Zn Fe-Al)For operating temperatures higher than 600 degC

aluminium jacketing should not be used

Self-tapping screw bold or rivet should be from the

same material as the jacketing

Surfaces with temperatures higher than 500 degC

should be insulated by more insulation layers in a

way that each layer has a different apparent density

Material with higher density insulates better under

higher temperatures than material with lower

density therefore insulation with higher density is

placed closer to the hot side Under low operating

temperatures thermal performance is almost equalSafety working principles must be kept for insulation

assembly

Isover products are packed into PE foil They must be

transported in covered vehicles under such conditions

to avoid moistening or other degradation They must

be stored in covered places

Wired mats

After the cutting of needed length the wired mat shall

be tightly wrapped on the pipe Wired matsrsquo butt jointsshould be in close contact to each other to ensure no

gaps between mats For multiple layer construction

each layer is staggered when applied Each layer must

be secured in place before the next is applied Individual

mats are bound together with a wire with minimal 07

mm thickness Alternatively wired hook or stainless

steel bands (with minimum width of 10 mm) can be

used Maximum distance between hooks is 150 mm

The decision to use multiple layers may be made for one

or more of the following reasons

to provide compensation for pipe expansion andcontraction

to reduce heat flow by staggering joints thus creating

a more thermally efficient installation

to achieve thickness in excess of manufacturersrsquo

capabilities

for retrofitting purposes

Lamella mats

Lamella mats Orstech LSP H consist of mineral wool

lamellas which have been glued to aluminium foil

reinforced with a glass fibre grid and these fibres are

predominantly perpendicular to the surface of themat Compressive strength but thermal conductivity

too are increased compared to mats with a fibre

orientation parallel to the surface (wired mats) Due

to its compressive strength resistance they have less

demands for undeconstruction (less thermal bridges)

in comparison with wired mats Temporary securing in

place is done by aluminium tapes final fixing shall be

done by a baling wire

Protective coverings

The efficiency and service of insulation is directly

dependent upon its protection from moisture entry andmechanical and chemical damage Choices of jacketing

materials are based upon the mechanical chemical

thermal and moisture conditions of the installation

as well as cost and appearance requirements The

basic function of the weather protection is to protect

the insulation from rain snow sleet wind solar

radiation atmospheric contamination and mechanical

damage With this definition in mind several service

requirements must be considered

PIPING INSULATION

For domestic hot water piping with smaller diameters

insulation pipe sections which are covered withaluminium foil are ideal Pipe sections with a facing

have a self-adhesive overlap in a longitudinal joint

to ensure perfect enclosure of a pipe section It is

recommended to secure pipe sections by an aluminium

tape or by galvanized wire transversely They are usually

knotted three times per meter more for pipe sections

with higher diameter Higher diameters should be

secured either by wire or by metal band (at least two

bands per meter)

Pipings with bigger diameters are most commonly

insulated by lamella mats Orstech LSP (stone woolinsulation) or Isover ML-3 (glass wool insulation)

eventually by wired mats Orstech DP (especially for higher

temperatures) Lamella and wired mats are also suitable

for appliances and vessels (both ends and cylindrical

parts) residential heating systems and air ducts

Internal mechanical forces ndash expansion and contraction

of the pipe or vessel must be considered because the

resulting forces are transferred to the external surface ofthe weather barrier Ability to slide elongate or contract

must be provided

External mechanical forces ndash mechanical abuse (ie

tools being dropped abrasion from wind-driven sand

personnel walking on the system) inflicted on a pipe or

vessel needs to be considered in design This may affect

insulation type as well as the weather barrier jacketing

type

Chemical resistance Some industrial environments may

have airborne or spilled corrosive agents that accumulate

on the weather barrier and chemically attack the pipe or

vessel jacketing Elements that create corrosive issues

must be well understood and accounted for Insulation

design of coastal facilities should account for chloride

attack

Galvanic corrosion Contacts between two different

types of metal must be considered for galvanic corrosion

potential Similarly water can act as an electrolyte and

galvanic corrosion can occur because of the differentpotential of the pipe and vessel and a metal jacketing

Materials used as weather barriers for insulation

Typical metal jacketing materials bare aluminium coated

aluminium stainless steel painted steel galvanized steel

aluminium-zinc coated steel

Typical polymeric jacketing materials polyvinyl chloride

(PVC) polyvinyliedene chloride (PVDC) polyisobutylene

multiple-layer composite materials (eg polymericfoil

mesh laminates) fabrics (silicone-impregnated fibreglass)

Fittings valves

Insulation of fittings valves flanges and couplings is

the most time consuming and often expensive aspectof commercial and industrial insulation But it is crucial

to insulate also these parts properly otherwise most of

energy will be transported by these thermal bridges For

example for 200 degC medium heat loss of one uninsulated

valve corresponds to one meter of uninsulated pipe or

ten meters of uninsulated pipe

Fittings are items used to change size direction of flow

level or assembly of piping They may be of the screwed

sweat or welded types Valves are any of various devices

that regulate liquid or gas flow and they may be of the

screwed sweated flanged or welded types Flanges areprotruding rims and edges of the screwed or sweated

type used with fittings valves couplings etc And finally

mechanical couplings are devices used in assembly of

piping Screwed and flanged connections on fittings

valves couplings etc usually require oversized insulation

applications to compensate for the protrusions

Minimum spacing between pipes and

constructions

It is essential to ensure sufficient space between pipies

and between a pipe and a wall (minimally 100 mm)

Otherwise there is a great danger of creating a zone withalmost no cenvenction The result can be too high surface

temperature (needed personal protection against burn)

or possibility of condensation on cold piping Besides

mounting would have been more difficult

DUCTING INSULATION

Isover products are designed to provide high levels of

thermal acoustic and fire protection insulation in HVACductwork applications such as rectangular flat oval and

circular ductwork

The most suitable insulation materials for ducts are

felts KLIMAROL with aluminium foil facing lamella mats

Orstech LSP or Isover ML-3 wired mats Orstech DP or

slabs Orstech H with aluminium foil facing

Duct insulation mounting

Insulation is mostly fixed to the duct by welded pinsWhen using Orstech H slabs with aluminium facing all

the joints shall be sealed with aluminium tape If a steel

clamping band is used it is necessary to use thin-walled

steel L-profiles to avoid trimming of the insulation If

using Orstech slabs without aluminium facing or Orstech

DP wired mats proper jacketing shall be made (the most

suitable is metal steel jacketing)

FIRE PROTECTION OF VENTILATION DUCT

Description

It is vital to develop safe durable and reliable solutions

for ventilation systems as fire can easily spread from the

point of origin via ductwork Isover meets the highest

standards for fire protection providing excellent fire

resistance and top-rated reaction to fire performance

Rectangular ducts shall be insulated by Orstech 65 H

slabs with 40 mm thickness (60 mm for fire resistance EI

60 for a horizontal duct) circular ducts shall be insulated

by Orstech LSP PYRO lamella mats with 50 mm thickness

By these solutions fire resistances EI 15 30 45 and 60 S

have been certified to comply with EN 1366-1

Orstech system with fire resistance has been proven to

meet the requirements of all possible scenarios for fire

from the outside The scenarios can be identified by duct

orientation and duct shape (see table below) Horizontal

ducts normally serve one floor of a building Vertical

ducts normally serve between floors of a building All

scenarios have been done only with one layer Insulation

is fixed to a duct by welded pins Such solution is time

and material saving

Metal ductworkThe steel duct is constructed in sections of galvanised

steel sheet or stainless steel sheet minimum 08 mm thick

(standard duct sheeting for rectangular ducts specified

in DIN 24190 for circular ducts in DIN 24145) Maximum

duct size for which classification protocol is valid is 1250

mm (width) x 1000 mm (height) for rectangular duct or

diameter up to 1000 mm for a circular duct

At each cross joint flanges are fastened to the duct

with spot welds at 150 mm nominal centres

Use a ceramic tape gasket and fire-stopping mastic

between the flanges to seal the joints

Flanges are bolted together with an M10 steel nut

and bolt at each corner

Fasten the flanges together with steel clamps with

bolts M8 (see the figure) in quantity of 3 clamps per 1

meter of the flange length

Drop rods and hangers

Rectangular ducts are suspended by threaded rods and

channel section bearers A duct shall be hung with asuspension system which is independently fire rated

according to EN 1363-1 Certificated suspension system

MUPRO is recommended for the purpose Each steel

hanger consists of two threaded drop rods minimum

M10 and a channel section bearer 3840 mm Fasten

the bearer to the drop rods using hexagonal nuts and

washers The drop rods can be positioned either inside

the insulation material or outside If drop rods are outside

there is no need to insulate them separately The bearers

are positioned inside the insulation material

Circular ducts are suspended by MUumlPRO steel hangerswhich consist of two threaded drop rods minimum

M10 and a two-part industrial circular band The ends

of each band section are bent outwards Fasten the band

sections together and attach them to the drop rods with

hexagonal nuts and washers Place these hangers inside

the insulation The rods do not need to be protected by

insulation

When fixing them to a concrete construction use all-

steel expanding anchors to fasten the threaded rod

hangers to concrete soffits The anchors should penetrate

the concrete by at least 60 mm When fixing to a steel

supporting construction drill a hole through the steel

member allowing the drop rod to be supported by a steel

nut and washer above If a clamp type fixing is used the

clamp must be steel suitable for the purpose It should

pass around the steel member and be fastened back on

itself Clamps that rely on friction to hold them in place

are not suitable

Insulation

Rectangular ducts are insulated by Orstech 65 H slabs

(with apparent density 65 kgm3 and with one-sidedaluminium foil facing) with 40 mm thickness (60 mm

for fire resistance EI 60 for a horizontal duct) Circular

ducts are insulated by lamella mats Orstech LSP PYRO

with 50 mm thickness Insulation slabs (lamella mats)

need to be cut to fit the duct as tightly as possible the

insulation may need to be cut to fit around flanged duct

joints Install the insulation so that one slab (lamella

mat) is adjacent and tightly fitted against the other No

gaps must be present between butt joints of insulation

Insulation can be easily cut with a standard laggers knife

There is no need for adhesive on joints All the joints shall

be sealed by aluminium tape For rectangular ducts in theposition of flange the slabs are snick first 15 mm of the

thickness to avoid lifting of the slabs Butt joints should

be positioned out of flanges Fire protective insulation for

circular ducts does not require usage of a wire net mesh

on the outer side of insulation

Stud welded pins

The insulation is fixed to the duct using steel pins 27 mm

to 3 mm nominal diameter and spring steel washers

minimum 30 mm diameter The length of pin should

be equal to the insulation thickness The orientational

number of pins is 16 piecesm2 for rectangular ducts and14 piecesm2 for circular ducts

Recommended distance from duct edges and joints is

80 mm 50 mm from flanges

Wallfloor penetration

At wallfloor penetration one must insure the same fire

resistance of ventilation duct as has the fire separation

to avoid the spreading of fire from one compartment to

other via a duct This is possible by two basic principles

or their combinations - install a fire damper at the

penetration point or use insulation with fire resistancewhere the crucial thing is the fire-stopping The fire-

stopping is from the second insulation layer with the

width of 150 mm from both side of fire separation

The same general principle is used for both rectangular

and circular ducts regardless of orientation Place

the duct in the penetration of the construction with

approximately 10 mm gap between insulated duct and

opening Before installing the fire-stopping with the

same insulation thickness as is used for the first layer

pack the space between the duct and partition with

as many pieces of insulation as possible Ensure tight

compression in order to completely fill the opening This

must be done because system ORSTECH Protect does

not require stiffeners inside the duct Then install thesecond insulation layer so that it is adjacent and tightly

fitted against the penetration The insulation must be

cut leaving excess length so that it exerts some pressure

between the penetration and the last fitted piece of

insulation

The second layer is fixed by welded pins with length

equal to double insulation thickness The second layer for

circular ducts (lamella mats) is clamped with 1-2 wires

with a diameter 16 mm Then the insulation is secured

to the duct by welded pins

A inovative solution is the considerable simplification of

a fire-stopping concept There is no need to use any kind

of stiffener either inside or outside of the duct A great

advantage is to mount the whole ventilation section

at once and the wall itself can be placed anywhere

Therefore the position variability of fire separation is

provided No glue or mastic is needed at wallfloor

penetrations

Fire classification

ORSTECH Protect insulation with fire resistance has

been tested by the fire testing laboratory Pavus as an

authorised body AO 216 Classification protocols on the

request

Fire protection system ORSTECH Protect has been tested

in accordance with EN 1366-1 Maximum size for the

rectangular duct is 1250 x 1000 mm and for the circular

duct up to diameter 1000 mm If a duct has bigger

dimensions the certificate connected to the standard

cannot be used

capabilities

for retrofitting purposes

Insulation is usually fixed by mechanical fasteners - by

studs or pins Spacing between them is dependent on the

design of the vessel its surface temperature fire hazard

potential involved and presumptive loading Each slab

should be fixed by minimally two pins

BOILER INSULATIONInsulations for boilers kettles and ovens are one of

the most demanding applications in industry because

these units are operating at very high temperatures

Good insulation not only saves energy considerably but

the main purpose is personal protection against burn

According to the surface shape and temperature are used

either slabs with higher densities Orstech 65 to 110 (for

boilers with flat surfaces) or wired mats Orstech DP 65 to

DP 100 (for boilers with cylindrical parts)

Boiler walls are exposed to very high temperatures

(usually around 500 or 600 degC) Therefore it is essential

to use mechanical fasteners for the fixing of insulation

to the surface Insulation for boilers is done in at least

two layers each layer must be staggered when applied

Each layer must be secured in place before the next is

applied A product with high density should be placed as

the first layer because it has a higher maximum surface

temperature (higher resistance against high operating

temperatures) and better insulation performace than

products with lower densities

CHIMNEY INSULATION

Insulations for prefabricated chimneys are directly

supplied by producers of such systems In cooperation

with specialized wholesale companies we offer slabs

with multi-plate stripes which allow easy and perfect

application for prefabricated chimneys suitable both

for stainless steel chimney liners as well as with other

brands of chimney lining systems The main advantage

is the time saving during the installation in comparison

with the use of lamella mats and horizontal orientation

of fibres (better thermal conductivity) Insulation

dimensions ie thickness of slabs and groove dimensions

dependent on the chimney diameter are supplied

according to customer needs

For non-prefabricated chimneys are mostly used wired

mats Orstech DP or slabs Orstech 90 or 110 (for chimneys

with rectangular cross-section)

TECHNOLOGICAL APPLIANCEINSULATIONWhere big quantities of energy is used eg within

petrochemical paper and pulp industries thermal

insulation is necessary in order to reduce expensive

energy losses Tanks vessels exhausts exchangers

and technological piping are appliances that are often

working at high temperatures Good insulation will save

energy considerably which will benefit the environment

and keep the working costs down At the same time

the insulation will reduce temperature fall which could

disturb the production process

Proper insulation can be chosen in accordance with

dimension surface temperature the manner of fixing

and requirements for jacketing For pipes and cylindrical

parts are used lamella mats Orstech LSP H and Isover

ML-3 (only for temperatures up to 250 degC) or wired mats

Orstech DP For appliances and vessels with rectangular

shapes Orstech slabs are suitable (type according to a

surface temperature) Slabs can have aluminium facing

If insulation is done in more than one layer each layer

is staggered when applied Each layer must be secured

in place before the next is applied The decision to use

multiple layers may be made for one or more of the

following reasons

FIRE PERFORMANCE

FIRE ndash a chemical reaction involving rapid oxidation or

burning of a fuel occurs only when three elements are

present in the proper conditions and proportions

FUEL ndash Fuel can be any combustible material - solid

liquid or gas Most solids and liquids become a vapour

or gas before they burn

OXYGEN ndash The air we breathe is about 21 oxygen Fire

only needs an atmosphere with at least 16 oxygen

HEAT ndash Heat is the energy necessary to increase the

temperature of the fuel to a point where sufficient

vapours are given off for ignition to occur

Fire development depends mostly on room geometry

and ventilation the fuel type the amount and surface

area of the fuel Fire is often discussed in terms of the

temperature development and can be divided into

different stages incipience (ignition) growth flashover

fully developed fire and decay

How materials behave in the early stages of a fire from

ignition to flashover (the spontaneous ignition of hot

smoke and gasses) needs to be assessed at the design

stage for buildings and also for plants and equipment

Euroclasses a new European harmonised classification

system for materialsrsquo reaction to fire in most Europeancountries replaced the old national standards The

Euroclass fire classification covers not only materials

used in building structures but it is being extended also

to technical insulations to cover building equipment

and industrial installations This will help to compare

the reaction to fire of different thermal insulation

materials

The classification levels are A1A2 (completely non-

combustible) B C D E and F A1A2 corresponds to

the safest situation E would be the most dangerous

situation and F would mean not classified

ISOVER mineral wool insulations are totally non-

combustible and completely fire safe achieving

Euroclass A1 fire rating (A2 for products with facing)when classified in accordance with EN 13501-1 One

of the most important issues studied under reaction to

fire performance is the potential for flashover to occur

which can lead to a fire spreading uncontrollably Isover

stone wool is not susceptible to flashover

This is a guide to common building materials and their

likely Euroclassification

Check with individual product manufactures for spedific

product specifications

REACTION TO FIRE

Smoke and flaming droplet risk(1) In the EU classification system for reaction to fire

a construction product will be classified as Euroclass A1

A2 B C D E or F depending on its tendency to burn

(2) The product testing will provide data represented

by the signs s1 s2 or s3 which indicate the tendency

to release smoke Smoke causes over 60 of deaths in

fire across the EU The measurement of smoke release

has been put into these 3 broad bands that can be

translated as ldquolittle or no smokerdquo s1 - rdquoquite a lot of

smokerdquo s2 - rdquosubstantial smoke releaserdquo s3

(3) Some construction products like these made of

polystyrene can melt and ignite to form Flaming

Droplets Wooden products on the other hand will tend

to char before the char falls away as Flaming Particles

to expose more material

These rdquoflaming dropletsparticlesrdquo will tend to

initiate new fires away from the original point of

ignition and must be considered when the products

are used horizontally in ceiling or roof applications

The classification system ranks the level of release of

flaming dropletsparticles as d0 (none) d1 (some) and

d2 (quite a lot)

FIRE PROTECTION DESIGN FOR VENTILATION DUCTS

Produced with the stone wool technology of Isover

fire protection system ORSTECH Protect is mineral

wool that combines all the advantages of conventionalthermal and acoustic insulation with top level of fire

safety Mineral wool insulations have the melting point

higher than 1000 degC From the fire protection point of

view products Isover are one of the safest materials

ORSTECH Protect consists of slab or lamella mat

solutions offering up to one hour fire protection for

both vertical and horizontal applications of rectangular

and circular ductwork systems

Passive protection of ventilation ducts is possible by

two basic means

Installed a fire damper into the duct to the place of

fire separation

Use a fire protection insulation system which is

tested according EN 1366-1 and has a classification

protocol in accordance with EN 13 501-3 This second

case is covered by insulation system ORSTECH

Protect

LEGISLATION

Air duct which shall resist the spread of fire from one

compartment to another is tested according to EN

1366-1 The standard can be applied to vertical and

horizontal ducts with or without branches for fire inside

or outside the duct The test measures the time period

for which ducts of specified dimensions suspended as

they would be in practice satisfy criteria when exposed

to fire from inside or outside (separately)

This standard is used in conjunction with EN 1363-1

which prescribes requirements for the determinationof fire resistance of various components of building

structures which are exposed to standard fire

conditions In this standard there are failure criteria

whereby it is possible to evaluate the ability of a tested

duct to prevent fire spread due to the destruction of

the duct (integrity failure E) heat transfer (insulationfailure I) and prevention of the smoke penetration

(smoke leakage S) Fire protection is expressed by time

in minutes for which failure criteria are fulfilled

Designation itself is then done according to

classification standard EN 13 501-3 Classification

states if criteria are fulfilled for fire outside (marking

o rarr i) valid for duct type A or fire inside (marking

irarr o) or from both directions (iharr o) valid for duct type

B and if this is valid for a horizontal duct (marking ho)

or a vertical one (ve) or both (ve ho) Eg class bdquoEI 30 S

ndash ve ho (orarr i) Sldquo represents duct capability to maintain

integrity insulation and smoke leakage for time period

of 30 minutes under fire exposure from outside both

for vertical and horizontal positions

MAXIMUM DUCT SIZES

Maximum size is according to EN 1366-1 for rectangular

duct 1250 x 1000 mm and for circular duct up to

diameter 1000 mm If a duct has bigger dimensions the

classification protocol cannot be used

ACOUSTIC PERFORMANCE

Noise is a sound which impacts negatively on the

surroundings Noise levels emanating from HVAC

services (pipework ductwork and air handlingequipment) and other services can be significantly

reduced with the use of Isover products which will

help to achieve acceptable environmental noise levels

Isover insulations are due to its fibre structure an ideal

material for sound attenuation not only for industrial

application The degree of sound insulation will depend

upon the application the thickness of insulation used

and the nature of any finish used to clad over the

installation In suitable frequencies they can absorb up

to 95 of the sound energy (α = 095)

SOUND ABSORPTIONWhen a sound wave strikes a surface the sound energy

is broken down into transmitted energy (through the

material) converted energy (usually heat) and reflected

energy (back towards the source of the sound)

The more absorbent the material the less sound is

reflected That part of sound energy which is converted

and transmitted is usually expressed as an absorption

coefficient α

The absorption coefficient for a material varies with

the frequency An absorbent layer of mineral wool

has the best absorption capacity in medium and high

frequencies The absorption in low frequencies is

improved by increasing the thickness or by providing an

air gap behind the absorbent layer

Examples of the effectiveness of Isover products in noise

control are given in the following table

ABSORPTIVE STRUCTURES

The most common task in room acoustics is to attenuate

or cancel some frequencies or a whole frequency band

This is possible to realise by using convenient absorptive

material or structures which are frequency-dependent

In this way we can control not only absorption ie

reverberation time but also suppress or completely

remove unpleasant sounds

In a porous material acoustic absorption is mainlycaused by friction in pores ie friction between

oscillating particles and the surface of pores Since the

energy loss due to friction is proportional to the length

of the path the most absorption will occur when the

porous material is placed in a position where the particle

displacement is the largest (maxima displacement)

When sound strikes a rigid wall like concrete for

example a standing wave result and the maxima of

particle displacement appear at the distances λ14

3λ24 5λ

34 hellip from the surface of a room These are the

critical distances which must be covered by adsorbers

ie layers with thicknesses d1 = λ

14 d

2 = 3λ

24 d

3 = 5λ

34

In short an absorber with a thickeness d placed directly

on the solid structure will effectively attenuate only

those frequencies where f ge c4d (c is the velocity of

sound 340 ms) For example insulation thickness

of 50 mm wil l reliably attenuate frequencies higher

than 1700 Hz thickness 100 mm then already from

frequencies 850 Hz The higher the frequency the

shorter the wave length and better attenuation

An absorbing layer tightly adjacent to a solid structure

has nevertheless one disadvantage To attenuate

low frequencies it would be necessary to use verythick layers (for example for attenuation of 500 Hz a

thickness of about 20 cm would be necessary) Therefore

acoustic tiles can hardly attenuate low frequency noise

(frequencies lower than 100 dB such as noise from

discotheques)

Fortunately it is possible to avoid expensive acoustic

tiles with high thickness If we use a very thin layer

and place it just in the position of the displacement

maximum of a chosen frequency this chosen frequency

and its odd multiples will be attenuated Acoustic

tiles thus work as a selective frequency filter On theselective basis also other acoustic attenuators work

namely membranes oscillating plates and resonators

ACOUSTICS INSULATIONS

Isover stone wool products with a high longitudinal air-

flow resistance (up to 95 kPasm2) and uniform porosity

(93 ndash 99 ) are used as sound attenuation insulations

In suitable frequencies they can absorb up to 95 of

the sound energy (α = 095) Sound attenuation in a

construction is related to elastic properties of Isover

mineral wool insulations and their low modulus of

elasticity (they have low dynamic toughness and

therefore they are much more suitable for acoustic

purposes in comparison with foam plastics)

Sound attenuation properties of Isover products are

characterised by an absorption coefficient α which

can be found in the table for three thicknesses andsix frequencies According to a given noise spectrum

it is possible to design a sound attenuation structure

of which our material is only a part Since we provide

only insulation material we launch only absorption

coefficients Final attenuation will be dependent on

the whole designed construction (considering also

supporting construction hangers) and assembly

Isover does not design sound attenuation and thus it

is necessary to ask specialists who are able to design a

proper structure

Generally we can say that transmission loss is higher

for constructions with higher plane weight therefore

in most cases insulation with higher density has

better sound attenuation (eg slabs Orstech 65 90

110 Isover FireProtect 150) than insulation with lower

density (eg Orstech 45) Slabs can be manufacturedwith a facing ndash glass black tissue

GENERAL RULES FOR USING ISOVER INSULATIONS

Between insulated piping sufficient distances must

be kept

Valves should be placed without needing to go on theinsulated pipes when handling them

Spindle of valves should not be installed in an upward

direction to avoid water leakage into the insulation

Surfaces before insulating must be clean and dry It

is not possible to insulate wet or frostbitten surfaces

which may later cause damages of insulation or

insulated surfaces

Dirt and rust must be rubbed down from untreated

carbon steels

Smear and oils must be removed by detergents or

solvents from insulated surfaces

Stainless steel surfaces must not be cleaned by

detergents or solvents with chloride content They

may be cleaned only by stainless steel brushes

Chloride solution attacks stainless steel surface and

causes stress corrosion cracking in the material With

increasing surface temperature the danger of stress

corrosion cracking is raised

Piping and equipment from stainless steel can be

insulated only by mineral wool insulation in AS

quality Such material can have maximum content

of chloride ions of 10 mg in 1 kg of the insulation

material

It is necessary to avoid contact of metals which can

cause galvanic corrosion (Cu-Zn Fe-Al)For operating temperatures higher than 600 degC

aluminium jacketing should not be used

Self-tapping screw bold or rivet should be from the

same material as the jacketing

Surfaces with temperatures higher than 500 degC

should be insulated by more insulation layers in a

way that each layer has a different apparent density

Material with higher density insulates better under

higher temperatures than material with lower

density therefore insulation with higher density is

placed closer to the hot side Under low operating

temperatures thermal performance is almost equalSafety working principles must be kept for insulation

assembly

Isover products are packed into PE foil They must be

transported in covered vehicles under such conditions

to avoid moistening or other degradation They must

be stored in covered places

Wired mats

After the cutting of needed length the wired mat shall

be tightly wrapped on the pipe Wired matsrsquo butt jointsshould be in close contact to each other to ensure no

gaps between mats For multiple layer construction

each layer is staggered when applied Each layer must

be secured in place before the next is applied Individual

mats are bound together with a wire with minimal 07

mm thickness Alternatively wired hook or stainless

steel bands (with minimum width of 10 mm) can be

used Maximum distance between hooks is 150 mm

The decision to use multiple layers may be made for one

or more of the following reasons

to provide compensation for pipe expansion andcontraction

to reduce heat flow by staggering joints thus creating

a more thermally efficient installation

to achieve thickness in excess of manufacturersrsquo

capabilities

for retrofitting purposes

Lamella mats

Lamella mats Orstech LSP H consist of mineral wool

lamellas which have been glued to aluminium foil

reinforced with a glass fibre grid and these fibres are

predominantly perpendicular to the surface of themat Compressive strength but thermal conductivity

too are increased compared to mats with a fibre

orientation parallel to the surface (wired mats) Due

to its compressive strength resistance they have less

demands for undeconstruction (less thermal bridges)

in comparison with wired mats Temporary securing in

place is done by aluminium tapes final fixing shall be

done by a baling wire

Protective coverings

The efficiency and service of insulation is directly

dependent upon its protection from moisture entry andmechanical and chemical damage Choices of jacketing

materials are based upon the mechanical chemical

thermal and moisture conditions of the installation

as well as cost and appearance requirements The

basic function of the weather protection is to protect

the insulation from rain snow sleet wind solar

radiation atmospheric contamination and mechanical

damage With this definition in mind several service

requirements must be considered

PIPING INSULATION

For domestic hot water piping with smaller diameters

insulation pipe sections which are covered withaluminium foil are ideal Pipe sections with a facing

have a self-adhesive overlap in a longitudinal joint

to ensure perfect enclosure of a pipe section It is

recommended to secure pipe sections by an aluminium

tape or by galvanized wire transversely They are usually

knotted three times per meter more for pipe sections

with higher diameter Higher diameters should be

secured either by wire or by metal band (at least two

bands per meter)

Pipings with bigger diameters are most commonly

insulated by lamella mats Orstech LSP (stone woolinsulation) or Isover ML-3 (glass wool insulation)

eventually by wired mats Orstech DP (especially for higher

temperatures) Lamella and wired mats are also suitable

for appliances and vessels (both ends and cylindrical

parts) residential heating systems and air ducts

Internal mechanical forces ndash expansion and contraction

of the pipe or vessel must be considered because the

resulting forces are transferred to the external surface ofthe weather barrier Ability to slide elongate or contract

must be provided

External mechanical forces ndash mechanical abuse (ie

tools being dropped abrasion from wind-driven sand

personnel walking on the system) inflicted on a pipe or

vessel needs to be considered in design This may affect

insulation type as well as the weather barrier jacketing

type

Chemical resistance Some industrial environments may

have airborne or spilled corrosive agents that accumulate

on the weather barrier and chemically attack the pipe or

vessel jacketing Elements that create corrosive issues

must be well understood and accounted for Insulation

design of coastal facilities should account for chloride

attack

Galvanic corrosion Contacts between two different

types of metal must be considered for galvanic corrosion

potential Similarly water can act as an electrolyte and

galvanic corrosion can occur because of the differentpotential of the pipe and vessel and a metal jacketing

Materials used as weather barriers for insulation

Typical metal jacketing materials bare aluminium coated

aluminium stainless steel painted steel galvanized steel

aluminium-zinc coated steel

Typical polymeric jacketing materials polyvinyl chloride

(PVC) polyvinyliedene chloride (PVDC) polyisobutylene

multiple-layer composite materials (eg polymericfoil

mesh laminates) fabrics (silicone-impregnated fibreglass)

Fittings valves

Insulation of fittings valves flanges and couplings is

the most time consuming and often expensive aspectof commercial and industrial insulation But it is crucial

to insulate also these parts properly otherwise most of

energy will be transported by these thermal bridges For

example for 200 degC medium heat loss of one uninsulated

valve corresponds to one meter of uninsulated pipe or

ten meters of uninsulated pipe

Fittings are items used to change size direction of flow

level or assembly of piping They may be of the screwed

sweat or welded types Valves are any of various devices

that regulate liquid or gas flow and they may be of the

screwed sweated flanged or welded types Flanges areprotruding rims and edges of the screwed or sweated

type used with fittings valves couplings etc And finally

mechanical couplings are devices used in assembly of

piping Screwed and flanged connections on fittings

valves couplings etc usually require oversized insulation

applications to compensate for the protrusions

Minimum spacing between pipes and

constructions

It is essential to ensure sufficient space between pipies

and between a pipe and a wall (minimally 100 mm)

Otherwise there is a great danger of creating a zone withalmost no cenvenction The result can be too high surface

temperature (needed personal protection against burn)

or possibility of condensation on cold piping Besides

mounting would have been more difficult

DUCTING INSULATION

Isover products are designed to provide high levels of

thermal acoustic and fire protection insulation in HVACductwork applications such as rectangular flat oval and

circular ductwork

The most suitable insulation materials for ducts are

felts KLIMAROL with aluminium foil facing lamella mats

Orstech LSP or Isover ML-3 wired mats Orstech DP or

slabs Orstech H with aluminium foil facing

Duct insulation mounting

Insulation is mostly fixed to the duct by welded pinsWhen using Orstech H slabs with aluminium facing all

the joints shall be sealed with aluminium tape If a steel

clamping band is used it is necessary to use thin-walled

steel L-profiles to avoid trimming of the insulation If

using Orstech slabs without aluminium facing or Orstech

DP wired mats proper jacketing shall be made (the most

suitable is metal steel jacketing)

FIRE PROTECTION OF VENTILATION DUCT

Description

It is vital to develop safe durable and reliable solutions

for ventilation systems as fire can easily spread from the

point of origin via ductwork Isover meets the highest

standards for fire protection providing excellent fire

resistance and top-rated reaction to fire performance

Rectangular ducts shall be insulated by Orstech 65 H

slabs with 40 mm thickness (60 mm for fire resistance EI

60 for a horizontal duct) circular ducts shall be insulated

by Orstech LSP PYRO lamella mats with 50 mm thickness

By these solutions fire resistances EI 15 30 45 and 60 S

have been certified to comply with EN 1366-1

Orstech system with fire resistance has been proven to

meet the requirements of all possible scenarios for fire

from the outside The scenarios can be identified by duct

orientation and duct shape (see table below) Horizontal

ducts normally serve one floor of a building Vertical

ducts normally serve between floors of a building All

scenarios have been done only with one layer Insulation

is fixed to a duct by welded pins Such solution is time

and material saving

Metal ductworkThe steel duct is constructed in sections of galvanised

steel sheet or stainless steel sheet minimum 08 mm thick

(standard duct sheeting for rectangular ducts specified

in DIN 24190 for circular ducts in DIN 24145) Maximum

duct size for which classification protocol is valid is 1250

mm (width) x 1000 mm (height) for rectangular duct or

diameter up to 1000 mm for a circular duct

At each cross joint flanges are fastened to the duct

with spot welds at 150 mm nominal centres

Use a ceramic tape gasket and fire-stopping mastic

between the flanges to seal the joints

Flanges are bolted together with an M10 steel nut

and bolt at each corner

Fasten the flanges together with steel clamps with

bolts M8 (see the figure) in quantity of 3 clamps per 1

meter of the flange length

Drop rods and hangers

Rectangular ducts are suspended by threaded rods and

channel section bearers A duct shall be hung with asuspension system which is independently fire rated

according to EN 1363-1 Certificated suspension system

MUPRO is recommended for the purpose Each steel

hanger consists of two threaded drop rods minimum

M10 and a channel section bearer 3840 mm Fasten

the bearer to the drop rods using hexagonal nuts and

washers The drop rods can be positioned either inside

the insulation material or outside If drop rods are outside

there is no need to insulate them separately The bearers

are positioned inside the insulation material

Circular ducts are suspended by MUumlPRO steel hangerswhich consist of two threaded drop rods minimum

M10 and a two-part industrial circular band The ends

of each band section are bent outwards Fasten the band

sections together and attach them to the drop rods with

hexagonal nuts and washers Place these hangers inside

the insulation The rods do not need to be protected by

insulation

When fixing them to a concrete construction use all-

steel expanding anchors to fasten the threaded rod

hangers to concrete soffits The anchors should penetrate

the concrete by at least 60 mm When fixing to a steel

supporting construction drill a hole through the steel

member allowing the drop rod to be supported by a steel

nut and washer above If a clamp type fixing is used the

clamp must be steel suitable for the purpose It should

pass around the steel member and be fastened back on

itself Clamps that rely on friction to hold them in place

are not suitable

Insulation

Rectangular ducts are insulated by Orstech 65 H slabs

(with apparent density 65 kgm3 and with one-sidedaluminium foil facing) with 40 mm thickness (60 mm

for fire resistance EI 60 for a horizontal duct) Circular

ducts are insulated by lamella mats Orstech LSP PYRO

with 50 mm thickness Insulation slabs (lamella mats)

need to be cut to fit the duct as tightly as possible the

insulation may need to be cut to fit around flanged duct

joints Install the insulation so that one slab (lamella

mat) is adjacent and tightly fitted against the other No

gaps must be present between butt joints of insulation

Insulation can be easily cut with a standard laggers knife

There is no need for adhesive on joints All the joints shall

be sealed by aluminium tape For rectangular ducts in theposition of flange the slabs are snick first 15 mm of the

thickness to avoid lifting of the slabs Butt joints should

be positioned out of flanges Fire protective insulation for

circular ducts does not require usage of a wire net mesh

on the outer side of insulation

Stud welded pins

The insulation is fixed to the duct using steel pins 27 mm

to 3 mm nominal diameter and spring steel washers

minimum 30 mm diameter The length of pin should

be equal to the insulation thickness The orientational

number of pins is 16 piecesm2 for rectangular ducts and14 piecesm2 for circular ducts

Recommended distance from duct edges and joints is

80 mm 50 mm from flanges

Wallfloor penetration

At wallfloor penetration one must insure the same fire

resistance of ventilation duct as has the fire separation

to avoid the spreading of fire from one compartment to

other via a duct This is possible by two basic principles

or their combinations - install a fire damper at the

penetration point or use insulation with fire resistancewhere the crucial thing is the fire-stopping The fire-

stopping is from the second insulation layer with the

width of 150 mm from both side of fire separation

The same general principle is used for both rectangular

and circular ducts regardless of orientation Place

the duct in the penetration of the construction with

approximately 10 mm gap between insulated duct and

opening Before installing the fire-stopping with the

same insulation thickness as is used for the first layer

pack the space between the duct and partition with

as many pieces of insulation as possible Ensure tight

compression in order to completely fill the opening This

must be done because system ORSTECH Protect does

not require stiffeners inside the duct Then install thesecond insulation layer so that it is adjacent and tightly

fitted against the penetration The insulation must be

cut leaving excess length so that it exerts some pressure

between the penetration and the last fitted piece of

insulation

The second layer is fixed by welded pins with length

equal to double insulation thickness The second layer for

circular ducts (lamella mats) is clamped with 1-2 wires

with a diameter 16 mm Then the insulation is secured

to the duct by welded pins

A inovative solution is the considerable simplification of

a fire-stopping concept There is no need to use any kind

of stiffener either inside or outside of the duct A great

advantage is to mount the whole ventilation section

at once and the wall itself can be placed anywhere

Therefore the position variability of fire separation is

provided No glue or mastic is needed at wallfloor

penetrations

Fire classification

ORSTECH Protect insulation with fire resistance has

been tested by the fire testing laboratory Pavus as an

authorised body AO 216 Classification protocols on the

request

Fire protection system ORSTECH Protect has been tested

in accordance with EN 1366-1 Maximum size for the

rectangular duct is 1250 x 1000 mm and for the circular

duct up to diameter 1000 mm If a duct has bigger

dimensions the certificate connected to the standard

cannot be used

to provide compensation for pipe expansion and

contraction

to reduce heat flow by staggering joints thus creatinga more thermally efficient installation

to achieve thickness in excess of manufacturersrsquo

capabilities

for retrofitting purposes

Insulation is usually fixed by mechanical fasteners - by

studs or pins Spacing between them is dependent on the

design of the vessel its surface temperature fire hazard

potential involved and presumptive loading Each slab

should be fixed by minimally two pins

BOILER INSULATIONInsulations for boilers kettles and ovens are one of

the most demanding applications in industry because

these units are operating at very high temperatures

Good insulation not only saves energy considerably but

the main purpose is personal protection against burn

According to the surface shape and temperature are used

either slabs with higher densities Orstech 65 to 110 (for

boilers with flat surfaces) or wired mats Orstech DP 65 to

DP 100 (for boilers with cylindrical parts)

Boiler walls are exposed to very high temperatures

(usually around 500 or 600 degC) Therefore it is essential

to use mechanical fasteners for the fixing of insulation

to the surface Insulation for boilers is done in at least

two layers each layer must be staggered when applied

Each layer must be secured in place before the next is

applied A product with high density should be placed as

the first layer because it has a higher maximum surface

temperature (higher resistance against high operating

temperatures) and better insulation performace than

products with lower densities

CHIMNEY INSULATION

Insulations for prefabricated chimneys are directly

supplied by producers of such systems In cooperation

with specialized wholesale companies we offer slabs

with multi-plate stripes which allow easy and perfect

application for prefabricated chimneys suitable both

for stainless steel chimney liners as well as with other

brands of chimney lining systems The main advantage

is the time saving during the installation in comparison

with the use of lamella mats and horizontal orientation

of fibres (better thermal conductivity) Insulation

dimensions ie thickness of slabs and groove dimensions

dependent on the chimney diameter are supplied

according to customer needs

For non-prefabricated chimneys are mostly used wired

mats Orstech DP or slabs Orstech 90 or 110 (for chimneys

with rectangular cross-section)

TECHNOLOGICAL APPLIANCEINSULATIONWhere big quantities of energy is used eg within

petrochemical paper and pulp industries thermal

insulation is necessary in order to reduce expensive

energy losses Tanks vessels exhausts exchangers

and technological piping are appliances that are often

working at high temperatures Good insulation will save

energy considerably which will benefit the environment

and keep the working costs down At the same time

the insulation will reduce temperature fall which could

disturb the production process

Proper insulation can be chosen in accordance with

dimension surface temperature the manner of fixing

and requirements for jacketing For pipes and cylindrical

parts are used lamella mats Orstech LSP H and Isover

ML-3 (only for temperatures up to 250 degC) or wired mats

Orstech DP For appliances and vessels with rectangular

shapes Orstech slabs are suitable (type according to a

surface temperature) Slabs can have aluminium facing

If insulation is done in more than one layer each layer

is staggered when applied Each layer must be secured

in place before the next is applied The decision to use

multiple layers may be made for one or more of the

following reasons

FIRE PROTECTION DESIGN FOR VENTILATION DUCTS

Produced with the stone wool technology of Isover

fire protection system ORSTECH Protect is mineral

wool that combines all the advantages of conventionalthermal and acoustic insulation with top level of fire

safety Mineral wool insulations have the melting point

higher than 1000 degC From the fire protection point of

view products Isover are one of the safest materials

ORSTECH Protect consists of slab or lamella mat

solutions offering up to one hour fire protection for

both vertical and horizontal applications of rectangular

and circular ductwork systems

Passive protection of ventilation ducts is possible by

two basic means

Installed a fire damper into the duct to the place of

fire separation

Use a fire protection insulation system which is

tested according EN 1366-1 and has a classification

protocol in accordance with EN 13 501-3 This second

case is covered by insulation system ORSTECH

Protect

LEGISLATION

Air duct which shall resist the spread of fire from one

compartment to another is tested according to EN

1366-1 The standard can be applied to vertical and

horizontal ducts with or without branches for fire inside

or outside the duct The test measures the time period

for which ducts of specified dimensions suspended as

they would be in practice satisfy criteria when exposed

to fire from inside or outside (separately)

This standard is used in conjunction with EN 1363-1

which prescribes requirements for the determinationof fire resistance of various components of building

structures which are exposed to standard fire

conditions In this standard there are failure criteria

whereby it is possible to evaluate the ability of a tested

duct to prevent fire spread due to the destruction of

the duct (integrity failure E) heat transfer (insulationfailure I) and prevention of the smoke penetration

(smoke leakage S) Fire protection is expressed by time

in minutes for which failure criteria are fulfilled

Designation itself is then done according to

classification standard EN 13 501-3 Classification

states if criteria are fulfilled for fire outside (marking

o rarr i) valid for duct type A or fire inside (marking

irarr o) or from both directions (iharr o) valid for duct type

B and if this is valid for a horizontal duct (marking ho)

or a vertical one (ve) or both (ve ho) Eg class bdquoEI 30 S

ndash ve ho (orarr i) Sldquo represents duct capability to maintain

integrity insulation and smoke leakage for time period

of 30 minutes under fire exposure from outside both

for vertical and horizontal positions

MAXIMUM DUCT SIZES

Maximum size is according to EN 1366-1 for rectangular

duct 1250 x 1000 mm and for circular duct up to

diameter 1000 mm If a duct has bigger dimensions the

classification protocol cannot be used

ACOUSTIC PERFORMANCE

Noise is a sound which impacts negatively on the

surroundings Noise levels emanating from HVAC

services (pipework ductwork and air handlingequipment) and other services can be significantly

reduced with the use of Isover products which will

help to achieve acceptable environmental noise levels

Isover insulations are due to its fibre structure an ideal

material for sound attenuation not only for industrial

application The degree of sound insulation will depend

upon the application the thickness of insulation used

and the nature of any finish used to clad over the

installation In suitable frequencies they can absorb up

to 95 of the sound energy (α = 095)

SOUND ABSORPTIONWhen a sound wave strikes a surface the sound energy

is broken down into transmitted energy (through the

material) converted energy (usually heat) and reflected

energy (back towards the source of the sound)

The more absorbent the material the less sound is

reflected That part of sound energy which is converted

and transmitted is usually expressed as an absorption

coefficient α

The absorption coefficient for a material varies with

the frequency An absorbent layer of mineral wool

has the best absorption capacity in medium and high

frequencies The absorption in low frequencies is

improved by increasing the thickness or by providing an

air gap behind the absorbent layer

Examples of the effectiveness of Isover products in noise

control are given in the following table

ABSORPTIVE STRUCTURES

The most common task in room acoustics is to attenuate

or cancel some frequencies or a whole frequency band

This is possible to realise by using convenient absorptive

material or structures which are frequency-dependent

In this way we can control not only absorption ie

reverberation time but also suppress or completely

remove unpleasant sounds

In a porous material acoustic absorption is mainlycaused by friction in pores ie friction between

oscillating particles and the surface of pores Since the

energy loss due to friction is proportional to the length

of the path the most absorption will occur when the

porous material is placed in a position where the particle

displacement is the largest (maxima displacement)

When sound strikes a rigid wall like concrete for

example a standing wave result and the maxima of

particle displacement appear at the distances λ14

3λ24 5λ

34 hellip from the surface of a room These are the

critical distances which must be covered by adsorbers

ie layers with thicknesses d1 = λ

14 d

2 = 3λ

24 d

3 = 5λ

34

In short an absorber with a thickeness d placed directly

on the solid structure will effectively attenuate only

those frequencies where f ge c4d (c is the velocity of

sound 340 ms) For example insulation thickness

of 50 mm wil l reliably attenuate frequencies higher

than 1700 Hz thickness 100 mm then already from

frequencies 850 Hz The higher the frequency the

shorter the wave length and better attenuation

An absorbing layer tightly adjacent to a solid structure

has nevertheless one disadvantage To attenuate

low frequencies it would be necessary to use verythick layers (for example for attenuation of 500 Hz a

thickness of about 20 cm would be necessary) Therefore

acoustic tiles can hardly attenuate low frequency noise

(frequencies lower than 100 dB such as noise from

discotheques)

Fortunately it is possible to avoid expensive acoustic

tiles with high thickness If we use a very thin layer

and place it just in the position of the displacement

maximum of a chosen frequency this chosen frequency

and its odd multiples will be attenuated Acoustic

tiles thus work as a selective frequency filter On theselective basis also other acoustic attenuators work

namely membranes oscillating plates and resonators

ACOUSTICS INSULATIONS

Isover stone wool products with a high longitudinal air-

flow resistance (up to 95 kPasm2) and uniform porosity

(93 ndash 99 ) are used as sound attenuation insulations

In suitable frequencies they can absorb up to 95 of

the sound energy (α = 095) Sound attenuation in a

construction is related to elastic properties of Isover

mineral wool insulations and their low modulus of

elasticity (they have low dynamic toughness and

therefore they are much more suitable for acoustic

purposes in comparison with foam plastics)

Sound attenuation properties of Isover products are

characterised by an absorption coefficient α which

can be found in the table for three thicknesses andsix frequencies According to a given noise spectrum

it is possible to design a sound attenuation structure

of which our material is only a part Since we provide

only insulation material we launch only absorption

coefficients Final attenuation will be dependent on

the whole designed construction (considering also

supporting construction hangers) and assembly

Isover does not design sound attenuation and thus it

is necessary to ask specialists who are able to design a

proper structure

Generally we can say that transmission loss is higher

for constructions with higher plane weight therefore

in most cases insulation with higher density has

better sound attenuation (eg slabs Orstech 65 90

110 Isover FireProtect 150) than insulation with lower

density (eg Orstech 45) Slabs can be manufacturedwith a facing ndash glass black tissue

GENERAL RULES FOR USING ISOVER INSULATIONS

Between insulated piping sufficient distances must

be kept

Valves should be placed without needing to go on theinsulated pipes when handling them

Spindle of valves should not be installed in an upward

direction to avoid water leakage into the insulation

Surfaces before insulating must be clean and dry It

is not possible to insulate wet or frostbitten surfaces

which may later cause damages of insulation or

insulated surfaces

Dirt and rust must be rubbed down from untreated

carbon steels

Smear and oils must be removed by detergents or

solvents from insulated surfaces

Stainless steel surfaces must not be cleaned by

detergents or solvents with chloride content They

may be cleaned only by stainless steel brushes

Chloride solution attacks stainless steel surface and

causes stress corrosion cracking in the material With

increasing surface temperature the danger of stress

corrosion cracking is raised

Piping and equipment from stainless steel can be

insulated only by mineral wool insulation in AS

quality Such material can have maximum content

of chloride ions of 10 mg in 1 kg of the insulation

material

It is necessary to avoid contact of metals which can

cause galvanic corrosion (Cu-Zn Fe-Al)For operating temperatures higher than 600 degC

aluminium jacketing should not be used

Self-tapping screw bold or rivet should be from the

same material as the jacketing

Surfaces with temperatures higher than 500 degC

should be insulated by more insulation layers in a

way that each layer has a different apparent density

Material with higher density insulates better under

higher temperatures than material with lower

density therefore insulation with higher density is

placed closer to the hot side Under low operating

temperatures thermal performance is almost equalSafety working principles must be kept for insulation

assembly

Isover products are packed into PE foil They must be

transported in covered vehicles under such conditions

to avoid moistening or other degradation They must

be stored in covered places

Wired mats

After the cutting of needed length the wired mat shall

be tightly wrapped on the pipe Wired matsrsquo butt jointsshould be in close contact to each other to ensure no

gaps between mats For multiple layer construction

each layer is staggered when applied Each layer must

be secured in place before the next is applied Individual

mats are bound together with a wire with minimal 07

mm thickness Alternatively wired hook or stainless

steel bands (with minimum width of 10 mm) can be

used Maximum distance between hooks is 150 mm

The decision to use multiple layers may be made for one

or more of the following reasons

to provide compensation for pipe expansion andcontraction

to reduce heat flow by staggering joints thus creating

a more thermally efficient installation

to achieve thickness in excess of manufacturersrsquo

capabilities

for retrofitting purposes

Lamella mats

Lamella mats Orstech LSP H consist of mineral wool

lamellas which have been glued to aluminium foil

reinforced with a glass fibre grid and these fibres are

predominantly perpendicular to the surface of themat Compressive strength but thermal conductivity

too are increased compared to mats with a fibre

orientation parallel to the surface (wired mats) Due

to its compressive strength resistance they have less

demands for undeconstruction (less thermal bridges)

in comparison with wired mats Temporary securing in

place is done by aluminium tapes final fixing shall be

done by a baling wire

Protective coverings

The efficiency and service of insulation is directly

dependent upon its protection from moisture entry andmechanical and chemical damage Choices of jacketing

materials are based upon the mechanical chemical

thermal and moisture conditions of the installation

as well as cost and appearance requirements The

basic function of the weather protection is to protect

the insulation from rain snow sleet wind solar

radiation atmospheric contamination and mechanical

damage With this definition in mind several service

requirements must be considered

PIPING INSULATION

For domestic hot water piping with smaller diameters

insulation pipe sections which are covered withaluminium foil are ideal Pipe sections with a facing

have a self-adhesive overlap in a longitudinal joint

to ensure perfect enclosure of a pipe section It is

recommended to secure pipe sections by an aluminium

tape or by galvanized wire transversely They are usually

knotted three times per meter more for pipe sections

with higher diameter Higher diameters should be

secured either by wire or by metal band (at least two

bands per meter)

Pipings with bigger diameters are most commonly

insulated by lamella mats Orstech LSP (stone woolinsulation) or Isover ML-3 (glass wool insulation)

eventually by wired mats Orstech DP (especially for higher

temperatures) Lamella and wired mats are also suitable

for appliances and vessels (both ends and cylindrical

parts) residential heating systems and air ducts

Internal mechanical forces ndash expansion and contraction

of the pipe or vessel must be considered because the

resulting forces are transferred to the external surface ofthe weather barrier Ability to slide elongate or contract

must be provided

External mechanical forces ndash mechanical abuse (ie

tools being dropped abrasion from wind-driven sand

personnel walking on the system) inflicted on a pipe or

vessel needs to be considered in design This may affect

insulation type as well as the weather barrier jacketing

type

Chemical resistance Some industrial environments may

have airborne or spilled corrosive agents that accumulate

on the weather barrier and chemically attack the pipe or

vessel jacketing Elements that create corrosive issues

must be well understood and accounted for Insulation

design of coastal facilities should account for chloride

attack

Galvanic corrosion Contacts between two different

types of metal must be considered for galvanic corrosion

potential Similarly water can act as an electrolyte and

galvanic corrosion can occur because of the differentpotential of the pipe and vessel and a metal jacketing

Materials used as weather barriers for insulation

Typical metal jacketing materials bare aluminium coated

aluminium stainless steel painted steel galvanized steel

aluminium-zinc coated steel

Typical polymeric jacketing materials polyvinyl chloride

(PVC) polyvinyliedene chloride (PVDC) polyisobutylene

multiple-layer composite materials (eg polymericfoil

mesh laminates) fabrics (silicone-impregnated fibreglass)

Fittings valves

Insulation of fittings valves flanges and couplings is

the most time consuming and often expensive aspectof commercial and industrial insulation But it is crucial

to insulate also these parts properly otherwise most of

energy will be transported by these thermal bridges For

example for 200 degC medium heat loss of one uninsulated

valve corresponds to one meter of uninsulated pipe or

ten meters of uninsulated pipe

Fittings are items used to change size direction of flow

level or assembly of piping They may be of the screwed

sweat or welded types Valves are any of various devices

that regulate liquid or gas flow and they may be of the

screwed sweated flanged or welded types Flanges areprotruding rims and edges of the screwed or sweated

type used with fittings valves couplings etc And finally

mechanical couplings are devices used in assembly of

piping Screwed and flanged connections on fittings

valves couplings etc usually require oversized insulation

applications to compensate for the protrusions

Minimum spacing between pipes and

constructions

It is essential to ensure sufficient space between pipies

and between a pipe and a wall (minimally 100 mm)

Otherwise there is a great danger of creating a zone withalmost no cenvenction The result can be too high surface

temperature (needed personal protection against burn)

or possibility of condensation on cold piping Besides

mounting would have been more difficult

DUCTING INSULATION

Isover products are designed to provide high levels of

thermal acoustic and fire protection insulation in HVACductwork applications such as rectangular flat oval and

circular ductwork

The most suitable insulation materials for ducts are

felts KLIMAROL with aluminium foil facing lamella mats

Orstech LSP or Isover ML-3 wired mats Orstech DP or

slabs Orstech H with aluminium foil facing

Duct insulation mounting

Insulation is mostly fixed to the duct by welded pinsWhen using Orstech H slabs with aluminium facing all

the joints shall be sealed with aluminium tape If a steel

clamping band is used it is necessary to use thin-walled

steel L-profiles to avoid trimming of the insulation If

using Orstech slabs without aluminium facing or Orstech

DP wired mats proper jacketing shall be made (the most

suitable is metal steel jacketing)

FIRE PROTECTION OF VENTILATION DUCT

Description

It is vital to develop safe durable and reliable solutions

for ventilation systems as fire can easily spread from the

point of origin via ductwork Isover meets the highest

standards for fire protection providing excellent fire

resistance and top-rated reaction to fire performance

Rectangular ducts shall be insulated by Orstech 65 H

slabs with 40 mm thickness (60 mm for fire resistance EI

60 for a horizontal duct) circular ducts shall be insulated

by Orstech LSP PYRO lamella mats with 50 mm thickness

By these solutions fire resistances EI 15 30 45 and 60 S

have been certified to comply with EN 1366-1

Orstech system with fire resistance has been proven to

meet the requirements of all possible scenarios for fire

from the outside The scenarios can be identified by duct

orientation and duct shape (see table below) Horizontal

ducts normally serve one floor of a building Vertical

ducts normally serve between floors of a building All

scenarios have been done only with one layer Insulation

is fixed to a duct by welded pins Such solution is time

and material saving

Metal ductworkThe steel duct is constructed in sections of galvanised

steel sheet or stainless steel sheet minimum 08 mm thick

(standard duct sheeting for rectangular ducts specified

in DIN 24190 for circular ducts in DIN 24145) Maximum

duct size for which classification protocol is valid is 1250

mm (width) x 1000 mm (height) for rectangular duct or

diameter up to 1000 mm for a circular duct

At each cross joint flanges are fastened to the duct

with spot welds at 150 mm nominal centres

Use a ceramic tape gasket and fire-stopping mastic

between the flanges to seal the joints

Flanges are bolted together with an M10 steel nut

and bolt at each corner

Fasten the flanges together with steel clamps with

bolts M8 (see the figure) in quantity of 3 clamps per 1

meter of the flange length

Drop rods and hangers

Rectangular ducts are suspended by threaded rods and

channel section bearers A duct shall be hung with asuspension system which is independently fire rated

according to EN 1363-1 Certificated suspension system

MUPRO is recommended for the purpose Each steel

hanger consists of two threaded drop rods minimum

M10 and a channel section bearer 3840 mm Fasten

the bearer to the drop rods using hexagonal nuts and

washers The drop rods can be positioned either inside

the insulation material or outside If drop rods are outside

there is no need to insulate them separately The bearers

are positioned inside the insulation material

Circular ducts are suspended by MUumlPRO steel hangerswhich consist of two threaded drop rods minimum

M10 and a two-part industrial circular band The ends

of each band section are bent outwards Fasten the band

sections together and attach them to the drop rods with

hexagonal nuts and washers Place these hangers inside

the insulation The rods do not need to be protected by

insulation

When fixing them to a concrete construction use all-

steel expanding anchors to fasten the threaded rod

hangers to concrete soffits The anchors should penetrate

the concrete by at least 60 mm When fixing to a steel

supporting construction drill a hole through the steel

member allowing the drop rod to be supported by a steel

nut and washer above If a clamp type fixing is used the

clamp must be steel suitable for the purpose It should

pass around the steel member and be fastened back on

itself Clamps that rely on friction to hold them in place

are not suitable

Insulation

Rectangular ducts are insulated by Orstech 65 H slabs

(with apparent density 65 kgm3 and with one-sidedaluminium foil facing) with 40 mm thickness (60 mm

for fire resistance EI 60 for a horizontal duct) Circular

ducts are insulated by lamella mats Orstech LSP PYRO

with 50 mm thickness Insulation slabs (lamella mats)

need to be cut to fit the duct as tightly as possible the

insulation may need to be cut to fit around flanged duct

joints Install the insulation so that one slab (lamella

mat) is adjacent and tightly fitted against the other No

gaps must be present between butt joints of insulation

Insulation can be easily cut with a standard laggers knife

There is no need for adhesive on joints All the joints shall

be sealed by aluminium tape For rectangular ducts in theposition of flange the slabs are snick first 15 mm of the

thickness to avoid lifting of the slabs Butt joints should

be positioned out of flanges Fire protective insulation for

circular ducts does not require usage of a wire net mesh

on the outer side of insulation

Stud welded pins

The insulation is fixed to the duct using steel pins 27 mm

to 3 mm nominal diameter and spring steel washers

minimum 30 mm diameter The length of pin should

be equal to the insulation thickness The orientational

number of pins is 16 piecesm2 for rectangular ducts and14 piecesm2 for circular ducts

Recommended distance from duct edges and joints is

80 mm 50 mm from flanges

Wallfloor penetration

At wallfloor penetration one must insure the same fire

resistance of ventilation duct as has the fire separation

to avoid the spreading of fire from one compartment to

other via a duct This is possible by two basic principles

or their combinations - install a fire damper at the

penetration point or use insulation with fire resistancewhere the crucial thing is the fire-stopping The fire-

stopping is from the second insulation layer with the

width of 150 mm from both side of fire separation

The same general principle is used for both rectangular

and circular ducts regardless of orientation Place

the duct in the penetration of the construction with

approximately 10 mm gap between insulated duct and

opening Before installing the fire-stopping with the

same insulation thickness as is used for the first layer

pack the space between the duct and partition with

as many pieces of insulation as possible Ensure tight

compression in order to completely fill the opening This

must be done because system ORSTECH Protect does

not require stiffeners inside the duct Then install thesecond insulation layer so that it is adjacent and tightly

fitted against the penetration The insulation must be

cut leaving excess length so that it exerts some pressure

between the penetration and the last fitted piece of

insulation

The second layer is fixed by welded pins with length

equal to double insulation thickness The second layer for

circular ducts (lamella mats) is clamped with 1-2 wires

with a diameter 16 mm Then the insulation is secured

to the duct by welded pins

A inovative solution is the considerable simplification of

a fire-stopping concept There is no need to use any kind

of stiffener either inside or outside of the duct A great

advantage is to mount the whole ventilation section

at once and the wall itself can be placed anywhere

Therefore the position variability of fire separation is

provided No glue or mastic is needed at wallfloor

penetrations

Fire classification

ORSTECH Protect insulation with fire resistance has

been tested by the fire testing laboratory Pavus as an

authorised body AO 216 Classification protocols on the

request

Fire protection system ORSTECH Protect has been tested

in accordance with EN 1366-1 Maximum size for the

rectangular duct is 1250 x 1000 mm and for the circular

duct up to diameter 1000 mm If a duct has bigger

dimensions the certificate connected to the standard

cannot be used

capabilities

for retrofitting purposes

Insulation is usually fixed by mechanical fasteners - by

studs or pins Spacing between them is dependent on the

design of the vessel its surface temperature fire hazard

potential involved and presumptive loading Each slab

should be fixed by minimally two pins

BOILER INSULATIONInsulations for boilers kettles and ovens are one of

the most demanding applications in industry because

these units are operating at very high temperatures

Good insulation not only saves energy considerably but

the main purpose is personal protection against burn

According to the surface shape and temperature are used

either slabs with higher densities Orstech 65 to 110 (for

boilers with flat surfaces) or wired mats Orstech DP 65 to

DP 100 (for boilers with cylindrical parts)

Boiler walls are exposed to very high temperatures

(usually around 500 or 600 degC) Therefore it is essential

to use mechanical fasteners for the fixing of insulation

to the surface Insulation for boilers is done in at least

two layers each layer must be staggered when applied

Each layer must be secured in place before the next is

applied A product with high density should be placed as

the first layer because it has a higher maximum surface

temperature (higher resistance against high operating

temperatures) and better insulation performace than

products with lower densities

CHIMNEY INSULATION

Insulations for prefabricated chimneys are directly

supplied by producers of such systems In cooperation

with specialized wholesale companies we offer slabs

with multi-plate stripes which allow easy and perfect

application for prefabricated chimneys suitable both

for stainless steel chimney liners as well as with other

brands of chimney lining systems The main advantage

is the time saving during the installation in comparison

with the use of lamella mats and horizontal orientation

of fibres (better thermal conductivity) Insulation

dimensions ie thickness of slabs and groove dimensions

dependent on the chimney diameter are supplied

according to customer needs

For non-prefabricated chimneys are mostly used wired

mats Orstech DP or slabs Orstech 90 or 110 (for chimneys

with rectangular cross-section)

TECHNOLOGICAL APPLIANCEINSULATIONWhere big quantities of energy is used eg within

petrochemical paper and pulp industries thermal

insulation is necessary in order to reduce expensive

energy losses Tanks vessels exhausts exchangers

and technological piping are appliances that are often

working at high temperatures Good insulation will save

energy considerably which will benefit the environment

and keep the working costs down At the same time

the insulation will reduce temperature fall which could

disturb the production process

Proper insulation can be chosen in accordance with

dimension surface temperature the manner of fixing

and requirements for jacketing For pipes and cylindrical

parts are used lamella mats Orstech LSP H and Isover

ML-3 (only for temperatures up to 250 degC) or wired mats

Orstech DP For appliances and vessels with rectangular

shapes Orstech slabs are suitable (type according to a

surface temperature) Slabs can have aluminium facing

If insulation is done in more than one layer each layer

is staggered when applied Each layer must be secured

in place before the next is applied The decision to use

multiple layers may be made for one or more of the

following reasons

ACOUSTIC PERFORMANCE

Noise is a sound which impacts negatively on the

surroundings Noise levels emanating from HVAC

services (pipework ductwork and air handlingequipment) and other services can be significantly

reduced with the use of Isover products which will

help to achieve acceptable environmental noise levels

Isover insulations are due to its fibre structure an ideal

material for sound attenuation not only for industrial

application The degree of sound insulation will depend

upon the application the thickness of insulation used

and the nature of any finish used to clad over the

installation In suitable frequencies they can absorb up

to 95 of the sound energy (α = 095)

SOUND ABSORPTIONWhen a sound wave strikes a surface the sound energy

is broken down into transmitted energy (through the

material) converted energy (usually heat) and reflected

energy (back towards the source of the sound)

The more absorbent the material the less sound is

reflected That part of sound energy which is converted

and transmitted is usually expressed as an absorption

coefficient α

The absorption coefficient for a material varies with

the frequency An absorbent layer of mineral wool

has the best absorption capacity in medium and high

frequencies The absorption in low frequencies is

improved by increasing the thickness or by providing an

air gap behind the absorbent layer

Examples of the effectiveness of Isover products in noise

control are given in the following table

ABSORPTIVE STRUCTURES

The most common task in room acoustics is to attenuate

or cancel some frequencies or a whole frequency band

This is possible to realise by using convenient absorptive

material or structures which are frequency-dependent

In this way we can control not only absorption ie

reverberation time but also suppress or completely

remove unpleasant sounds

In a porous material acoustic absorption is mainlycaused by friction in pores ie friction between

oscillating particles and the surface of pores Since the

energy loss due to friction is proportional to the length

of the path the most absorption will occur when the

porous material is placed in a position where the particle

displacement is the largest (maxima displacement)

When sound strikes a rigid wall like concrete for

example a standing wave result and the maxima of

particle displacement appear at the distances λ14

3λ24 5λ

34 hellip from the surface of a room These are the

critical distances which must be covered by adsorbers

ie layers with thicknesses d1 = λ

14 d

2 = 3λ

24 d

3 = 5λ

34

In short an absorber with a thickeness d placed directly

on the solid structure will effectively attenuate only

those frequencies where f ge c4d (c is the velocity of

sound 340 ms) For example insulation thickness

of 50 mm wil l reliably attenuate frequencies higher

than 1700 Hz thickness 100 mm then already from

frequencies 850 Hz The higher the frequency the

shorter the wave length and better attenuation

An absorbing layer tightly adjacent to a solid structure

has nevertheless one disadvantage To attenuate

low frequencies it would be necessary to use verythick layers (for example for attenuation of 500 Hz a

thickness of about 20 cm would be necessary) Therefore

acoustic tiles can hardly attenuate low frequency noise

(frequencies lower than 100 dB such as noise from

discotheques)

Fortunately it is possible to avoid expensive acoustic

tiles with high thickness If we use a very thin layer

and place it just in the position of the displacement

maximum of a chosen frequency this chosen frequency

and its odd multiples will be attenuated Acoustic

tiles thus work as a selective frequency filter On theselective basis also other acoustic attenuators work

namely membranes oscillating plates and resonators

ACOUSTICS INSULATIONS

Isover stone wool products with a high longitudinal air-

flow resistance (up to 95 kPasm2) and uniform porosity

(93 ndash 99 ) are used as sound attenuation insulations

In suitable frequencies they can absorb up to 95 of

the sound energy (α = 095) Sound attenuation in a

construction is related to elastic properties of Isover

mineral wool insulations and their low modulus of

elasticity (they have low dynamic toughness and

therefore they are much more suitable for acoustic

purposes in comparison with foam plastics)

Sound attenuation properties of Isover products are

characterised by an absorption coefficient α which

can be found in the table for three thicknesses andsix frequencies According to a given noise spectrum

it is possible to design a sound attenuation structure

of which our material is only a part Since we provide

only insulation material we launch only absorption

coefficients Final attenuation will be dependent on

the whole designed construction (considering also

supporting construction hangers) and assembly

Isover does not design sound attenuation and thus it

is necessary to ask specialists who are able to design a

proper structure

Generally we can say that transmission loss is higher

for constructions with higher plane weight therefore

in most cases insulation with higher density has

better sound attenuation (eg slabs Orstech 65 90

110 Isover FireProtect 150) than insulation with lower

density (eg Orstech 45) Slabs can be manufacturedwith a facing ndash glass black tissue

GENERAL RULES FOR USING ISOVER INSULATIONS

Between insulated piping sufficient distances must

be kept

Valves should be placed without needing to go on theinsulated pipes when handling them

Spindle of valves should not be installed in an upward

direction to avoid water leakage into the insulation

Surfaces before insulating must be clean and dry It

is not possible to insulate wet or frostbitten surfaces

which may later cause damages of insulation or

insulated surfaces

Dirt and rust must be rubbed down from untreated

carbon steels

Smear and oils must be removed by detergents or

solvents from insulated surfaces

Stainless steel surfaces must not be cleaned by

detergents or solvents with chloride content They

may be cleaned only by stainless steel brushes

Chloride solution attacks stainless steel surface and

causes stress corrosion cracking in the material With

increasing surface temperature the danger of stress

corrosion cracking is raised

Piping and equipment from stainless steel can be

insulated only by mineral wool insulation in AS

quality Such material can have maximum content

of chloride ions of 10 mg in 1 kg of the insulation

material

It is necessary to avoid contact of metals which can

cause galvanic corrosion (Cu-Zn Fe-Al)For operating temperatures higher than 600 degC

aluminium jacketing should not be used

Self-tapping screw bold or rivet should be from the

same material as the jacketing

Surfaces with temperatures higher than 500 degC

should be insulated by more insulation layers in a

way that each layer has a different apparent density

Material with higher density insulates better under

higher temperatures than material with lower

density therefore insulation with higher density is

placed closer to the hot side Under low operating

temperatures thermal performance is almost equalSafety working principles must be kept for insulation

assembly

Isover products are packed into PE foil They must be

transported in covered vehicles under such conditions

to avoid moistening or other degradation They must

be stored in covered places

Wired mats

After the cutting of needed length the wired mat shall

be tightly wrapped on the pipe Wired matsrsquo butt jointsshould be in close contact to each other to ensure no

gaps between mats For multiple layer construction

each layer is staggered when applied Each layer must

be secured in place before the next is applied Individual

mats are bound together with a wire with minimal 07

mm thickness Alternatively wired hook or stainless

steel bands (with minimum width of 10 mm) can be

used Maximum distance between hooks is 150 mm

The decision to use multiple layers may be made for one

or more of the following reasons

to provide compensation for pipe expansion andcontraction

to reduce heat flow by staggering joints thus creating

a more thermally efficient installation

to achieve thickness in excess of manufacturersrsquo

capabilities

for retrofitting purposes

Lamella mats

Lamella mats Orstech LSP H consist of mineral wool

lamellas which have been glued to aluminium foil

reinforced with a glass fibre grid and these fibres are

predominantly perpendicular to the surface of themat Compressive strength but thermal conductivity

too are increased compared to mats with a fibre

orientation parallel to the surface (wired mats) Due

to its compressive strength resistance they have less

demands for undeconstruction (less thermal bridges)

in comparison with wired mats Temporary securing in

place is done by aluminium tapes final fixing shall be

done by a baling wire

Protective coverings

The efficiency and service of insulation is directly

dependent upon its protection from moisture entry andmechanical and chemical damage Choices of jacketing

materials are based upon the mechanical chemical

thermal and moisture conditions of the installation

as well as cost and appearance requirements The

basic function of the weather protection is to protect

the insulation from rain snow sleet wind solar

radiation atmospheric contamination and mechanical

damage With this definition in mind several service

requirements must be considered

PIPING INSULATION

For domestic hot water piping with smaller diameters

insulation pipe sections which are covered withaluminium foil are ideal Pipe sections with a facing

have a self-adhesive overlap in a longitudinal joint

to ensure perfect enclosure of a pipe section It is

recommended to secure pipe sections by an aluminium

tape or by galvanized wire transversely They are usually

knotted three times per meter more for pipe sections

with higher diameter Higher diameters should be

secured either by wire or by metal band (at least two

bands per meter)

Pipings with bigger diameters are most commonly

insulated by lamella mats Orstech LSP (stone woolinsulation) or Isover ML-3 (glass wool insulation)

eventually by wired mats Orstech DP (especially for higher

temperatures) Lamella and wired mats are also suitable

for appliances and vessels (both ends and cylindrical

parts) residential heating systems and air ducts

Internal mechanical forces ndash expansion and contraction

of the pipe or vessel must be considered because the

resulting forces are transferred to the external surface ofthe weather barrier Ability to slide elongate or contract

must be provided

External mechanical forces ndash mechanical abuse (ie

tools being dropped abrasion from wind-driven sand

personnel walking on the system) inflicted on a pipe or

vessel needs to be considered in design This may affect

insulation type as well as the weather barrier jacketing

type

Chemical resistance Some industrial environments may

have airborne or spilled corrosive agents that accumulate

on the weather barrier and chemically attack the pipe or

vessel jacketing Elements that create corrosive issues

must be well understood and accounted for Insulation

design of coastal facilities should account for chloride

attack

Galvanic corrosion Contacts between two different

types of metal must be considered for galvanic corrosion

potential Similarly water can act as an electrolyte and

galvanic corrosion can occur because of the differentpotential of the pipe and vessel and a metal jacketing

Materials used as weather barriers for insulation

Typical metal jacketing materials bare aluminium coated

aluminium stainless steel painted steel galvanized steel

aluminium-zinc coated steel

Typical polymeric jacketing materials polyvinyl chloride

(PVC) polyvinyliedene chloride (PVDC) polyisobutylene

multiple-layer composite materials (eg polymericfoil

mesh laminates) fabrics (silicone-impregnated fibreglass)

Fittings valves

Insulation of fittings valves flanges and couplings is

the most time consuming and often expensive aspectof commercial and industrial insulation But it is crucial

to insulate also these parts properly otherwise most of

energy will be transported by these thermal bridges For

example for 200 degC medium heat loss of one uninsulated

valve corresponds to one meter of uninsulated pipe or

ten meters of uninsulated pipe

Fittings are items used to change size direction of flow

level or assembly of piping They may be of the screwed

sweat or welded types Valves are any of various devices

that regulate liquid or gas flow and they may be of the

screwed sweated flanged or welded types Flanges areprotruding rims and edges of the screwed or sweated

type used with fittings valves couplings etc And finally

mechanical couplings are devices used in assembly of

piping Screwed and flanged connections on fittings

valves couplings etc usually require oversized insulation

applications to compensate for the protrusions

Minimum spacing between pipes and

constructions

It is essential to ensure sufficient space between pipies

and between a pipe and a wall (minimally 100 mm)

Otherwise there is a great danger of creating a zone withalmost no cenvenction The result can be too high surface

temperature (needed personal protection against burn)

or possibility of condensation on cold piping Besides

mounting would have been more difficult

DUCTING INSULATION

Isover products are designed to provide high levels of

thermal acoustic and fire protection insulation in HVACductwork applications such as rectangular flat oval and

circular ductwork

The most suitable insulation materials for ducts are

felts KLIMAROL with aluminium foil facing lamella mats

Orstech LSP or Isover ML-3 wired mats Orstech DP or

slabs Orstech H with aluminium foil facing

Duct insulation mounting

Insulation is mostly fixed to the duct by welded pinsWhen using Orstech H slabs with aluminium facing all

the joints shall be sealed with aluminium tape If a steel

clamping band is used it is necessary to use thin-walled

steel L-profiles to avoid trimming of the insulation If

using Orstech slabs without aluminium facing or Orstech

DP wired mats proper jacketing shall be made (the most

suitable is metal steel jacketing)

FIRE PROTECTION OF VENTILATION DUCT

Description

It is vital to develop safe durable and reliable solutions

for ventilation systems as fire can easily spread from the

point of origin via ductwork Isover meets the highest

standards for fire protection providing excellent fire

resistance and top-rated reaction to fire performance

Rectangular ducts shall be insulated by Orstech 65 H

slabs with 40 mm thickness (60 mm for fire resistance EI

60 for a horizontal duct) circular ducts shall be insulated

by Orstech LSP PYRO lamella mats with 50 mm thickness

By these solutions fire resistances EI 15 30 45 and 60 S

have been certified to comply with EN 1366-1

Orstech system with fire resistance has been proven to

meet the requirements of all possible scenarios for fire

from the outside The scenarios can be identified by duct

orientation and duct shape (see table below) Horizontal

ducts normally serve one floor of a building Vertical

ducts normally serve between floors of a building All

scenarios have been done only with one layer Insulation

is fixed to a duct by welded pins Such solution is time

and material saving

Metal ductworkThe steel duct is constructed in sections of galvanised

steel sheet or stainless steel sheet minimum 08 mm thick

(standard duct sheeting for rectangular ducts specified

in DIN 24190 for circular ducts in DIN 24145) Maximum

duct size for which classification protocol is valid is 1250

mm (width) x 1000 mm (height) for rectangular duct or

diameter up to 1000 mm for a circular duct

At each cross joint flanges are fastened to the duct

with spot welds at 150 mm nominal centres

Use a ceramic tape gasket and fire-stopping mastic

between the flanges to seal the joints

Flanges are bolted together with an M10 steel nut

and bolt at each corner

Fasten the flanges together with steel clamps with

bolts M8 (see the figure) in quantity of 3 clamps per 1

meter of the flange length

Drop rods and hangers

Rectangular ducts are suspended by threaded rods and

channel section bearers A duct shall be hung with asuspension system which is independently fire rated

according to EN 1363-1 Certificated suspension system

MUPRO is recommended for the purpose Each steel

hanger consists of two threaded drop rods minimum

M10 and a channel section bearer 3840 mm Fasten

the bearer to the drop rods using hexagonal nuts and

washers The drop rods can be positioned either inside

the insulation material or outside If drop rods are outside

there is no need to insulate them separately The bearers

are positioned inside the insulation material

Circular ducts are suspended by MUumlPRO steel hangerswhich consist of two threaded drop rods minimum

M10 and a two-part industrial circular band The ends

of each band section are bent outwards Fasten the band

sections together and attach them to the drop rods with

hexagonal nuts and washers Place these hangers inside

the insulation The rods do not need to be protected by

insulation

When fixing them to a concrete construction use all-

steel expanding anchors to fasten the threaded rod

hangers to concrete soffits The anchors should penetrate

the concrete by at least 60 mm When fixing to a steel

supporting construction drill a hole through the steel

member allowing the drop rod to be supported by a steel

nut and washer above If a clamp type fixing is used the

clamp must be steel suitable for the purpose It should

pass around the steel member and be fastened back on

itself Clamps that rely on friction to hold them in place

are not suitable

Insulation

Rectangular ducts are insulated by Orstech 65 H slabs

(with apparent density 65 kgm3 and with one-sidedaluminium foil facing) with 40 mm thickness (60 mm

for fire resistance EI 60 for a horizontal duct) Circular

ducts are insulated by lamella mats Orstech LSP PYRO

with 50 mm thickness Insulation slabs (lamella mats)

need to be cut to fit the duct as tightly as possible the

insulation may need to be cut to fit around flanged duct

joints Install the insulation so that one slab (lamella

mat) is adjacent and tightly fitted against the other No

gaps must be present between butt joints of insulation

Insulation can be easily cut with a standard laggers knife

There is no need for adhesive on joints All the joints shall

be sealed by aluminium tape For rectangular ducts in theposition of flange the slabs are snick first 15 mm of the

thickness to avoid lifting of the slabs Butt joints should

be positioned out of flanges Fire protective insulation for

circular ducts does not require usage of a wire net mesh

on the outer side of insulation

Stud welded pins

The insulation is fixed to the duct using steel pins 27 mm

to 3 mm nominal diameter and spring steel washers

minimum 30 mm diameter The length of pin should

be equal to the insulation thickness The orientational

number of pins is 16 piecesm2 for rectangular ducts and14 piecesm2 for circular ducts

Recommended distance from duct edges and joints is

80 mm 50 mm from flanges

Wallfloor penetration

At wallfloor penetration one must insure the same fire

resistance of ventilation duct as has the fire separation

to avoid the spreading of fire from one compartment to

other via a duct This is possible by two basic principles

or their combinations - install a fire damper at the

penetration point or use insulation with fire resistancewhere the crucial thing is the fire-stopping The fire-

stopping is from the second insulation layer with the

width of 150 mm from both side of fire separation

The same general principle is used for both rectangular

and circular ducts regardless of orientation Place

the duct in the penetration of the construction with

approximately 10 mm gap between insulated duct and

opening Before installing the fire-stopping with the

same insulation thickness as is used for the first layer

pack the space between the duct and partition with

as many pieces of insulation as possible Ensure tight

compression in order to completely fill the opening This

must be done because system ORSTECH Protect does

not require stiffeners inside the duct Then install thesecond insulation layer so that it is adjacent and tightly

fitted against the penetration The insulation must be

cut leaving excess length so that it exerts some pressure

between the penetration and the last fitted piece of

insulation

The second layer is fixed by welded pins with length

equal to double insulation thickness The second layer for

circular ducts (lamella mats) is clamped with 1-2 wires

with a diameter 16 mm Then the insulation is secured

to the duct by welded pins

A inovative solution is the considerable simplification of

a fire-stopping concept There is no need to use any kind

of stiffener either inside or outside of the duct A great

advantage is to mount the whole ventilation section

at once and the wall itself can be placed anywhere

Therefore the position variability of fire separation is

provided No glue or mastic is needed at wallfloor

penetrations

Fire classification

ORSTECH Protect insulation with fire resistance has

been tested by the fire testing laboratory Pavus as an

authorised body AO 216 Classification protocols on the

request

Fire protection system ORSTECH Protect has been tested

in accordance with EN 1366-1 Maximum size for the

rectangular duct is 1250 x 1000 mm and for the circular

duct up to diameter 1000 mm If a duct has bigger

dimensions the certificate connected to the standard

cannot be used

capabilities

for retrofitting purposes

Insulation is usually fixed by mechanical fasteners - by

studs or pins Spacing between them is dependent on the

design of the vessel its surface temperature fire hazard

potential involved and presumptive loading Each slab

should be fixed by minimally two pins

BOILER INSULATIONInsulations for boilers kettles and ovens are one of

the most demanding applications in industry because

these units are operating at very high temperatures

Good insulation not only saves energy considerably but

the main purpose is personal protection against burn

According to the surface shape and temperature are used

either slabs with higher densities Orstech 65 to 110 (for

boilers with flat surfaces) or wired mats Orstech DP 65 to

DP 100 (for boilers with cylindrical parts)

Boiler walls are exposed to very high temperatures

(usually around 500 or 600 degC) Therefore it is essential

to use mechanical fasteners for the fixing of insulation

to the surface Insulation for boilers is done in at least

two layers each layer must be staggered when applied

Each layer must be secured in place before the next is

applied A product with high density should be placed as

the first layer because it has a higher maximum surface

temperature (higher resistance against high operating

temperatures) and better insulation performace than

products with lower densities

CHIMNEY INSULATION

Insulations for prefabricated chimneys are directly

supplied by producers of such systems In cooperation

with specialized wholesale companies we offer slabs

with multi-plate stripes which allow easy and perfect

application for prefabricated chimneys suitable both

for stainless steel chimney liners as well as with other

brands of chimney lining systems The main advantage

is the time saving during the installation in comparison

with the use of lamella mats and horizontal orientation

of fibres (better thermal conductivity) Insulation

dimensions ie thickness of slabs and groove dimensions

dependent on the chimney diameter are supplied

according to customer needs

For non-prefabricated chimneys are mostly used wired

mats Orstech DP or slabs Orstech 90 or 110 (for chimneys

with rectangular cross-section)

TECHNOLOGICAL APPLIANCEINSULATIONWhere big quantities of energy is used eg within

petrochemical paper and pulp industries thermal

insulation is necessary in order to reduce expensive

energy losses Tanks vessels exhausts exchangers

and technological piping are appliances that are often

working at high temperatures Good insulation will save

energy considerably which will benefit the environment

and keep the working costs down At the same time

the insulation will reduce temperature fall which could

disturb the production process

Proper insulation can be chosen in accordance with

dimension surface temperature the manner of fixing

and requirements for jacketing For pipes and cylindrical

parts are used lamella mats Orstech LSP H and Isover

ML-3 (only for temperatures up to 250 degC) or wired mats

Orstech DP For appliances and vessels with rectangular

shapes Orstech slabs are suitable (type according to a

surface temperature) Slabs can have aluminium facing

If insulation is done in more than one layer each layer

is staggered when applied Each layer must be secured

in place before the next is applied The decision to use

multiple layers may be made for one or more of the

following reasons

ACOUSTICS INSULATIONS

Isover stone wool products with a high longitudinal air-

flow resistance (up to 95 kPasm2) and uniform porosity

(93 ndash 99 ) are used as sound attenuation insulations

In suitable frequencies they can absorb up to 95 of

the sound energy (α = 095) Sound attenuation in a

construction is related to elastic properties of Isover

mineral wool insulations and their low modulus of

elasticity (they have low dynamic toughness and

therefore they are much more suitable for acoustic

purposes in comparison with foam plastics)

Sound attenuation properties of Isover products are

characterised by an absorption coefficient α which

can be found in the table for three thicknesses andsix frequencies According to a given noise spectrum

it is possible to design a sound attenuation structure

of which our material is only a part Since we provide

only insulation material we launch only absorption

coefficients Final attenuation will be dependent on

the whole designed construction (considering also

supporting construction hangers) and assembly

Isover does not design sound attenuation and thus it

is necessary to ask specialists who are able to design a

proper structure

Generally we can say that transmission loss is higher

for constructions with higher plane weight therefore

in most cases insulation with higher density has

better sound attenuation (eg slabs Orstech 65 90

110 Isover FireProtect 150) than insulation with lower

density (eg Orstech 45) Slabs can be manufacturedwith a facing ndash glass black tissue

GENERAL RULES FOR USING ISOVER INSULATIONS

Between insulated piping sufficient distances must

be kept

Valves should be placed without needing to go on theinsulated pipes when handling them

Spindle of valves should not be installed in an upward

direction to avoid water leakage into the insulation

Surfaces before insulating must be clean and dry It

is not possible to insulate wet or frostbitten surfaces

which may later cause damages of insulation or

insulated surfaces

Dirt and rust must be rubbed down from untreated

carbon steels

Smear and oils must be removed by detergents or

solvents from insulated surfaces

Stainless steel surfaces must not be cleaned by

detergents or solvents with chloride content They

may be cleaned only by stainless steel brushes

Chloride solution attacks stainless steel surface and

causes stress corrosion cracking in the material With

increasing surface temperature the danger of stress

corrosion cracking is raised

Piping and equipment from stainless steel can be

insulated only by mineral wool insulation in AS

quality Such material can have maximum content

of chloride ions of 10 mg in 1 kg of the insulation

material

It is necessary to avoid contact of metals which can

cause galvanic corrosion (Cu-Zn Fe-Al)For operating temperatures higher than 600 degC

aluminium jacketing should not be used

Self-tapping screw bold or rivet should be from the

same material as the jacketing

Surfaces with temperatures higher than 500 degC

should be insulated by more insulation layers in a

way that each layer has a different apparent density

Material with higher density insulates better under

higher temperatures than material with lower

density therefore insulation with higher density is

placed closer to the hot side Under low operating

temperatures thermal performance is almost equalSafety working principles must be kept for insulation

assembly

Isover products are packed into PE foil They must be

transported in covered vehicles under such conditions

to avoid moistening or other degradation They must

be stored in covered places

Wired mats

After the cutting of needed length the wired mat shall

be tightly wrapped on the pipe Wired matsrsquo butt jointsshould be in close contact to each other to ensure no

gaps between mats For multiple layer construction

each layer is staggered when applied Each layer must

be secured in place before the next is applied Individual

mats are bound together with a wire with minimal 07

mm thickness Alternatively wired hook or stainless

steel bands (with minimum width of 10 mm) can be

used Maximum distance between hooks is 150 mm

The decision to use multiple layers may be made for one

or more of the following reasons

to provide compensation for pipe expansion andcontraction

to reduce heat flow by staggering joints thus creating

a more thermally efficient installation

to achieve thickness in excess of manufacturersrsquo

capabilities

for retrofitting purposes

Lamella mats

Lamella mats Orstech LSP H consist of mineral wool

lamellas which have been glued to aluminium foil

reinforced with a glass fibre grid and these fibres are

predominantly perpendicular to the surface of themat Compressive strength but thermal conductivity

too are increased compared to mats with a fibre

orientation parallel to the surface (wired mats) Due

to its compressive strength resistance they have less

demands for undeconstruction (less thermal bridges)

in comparison with wired mats Temporary securing in

place is done by aluminium tapes final fixing shall be

done by a baling wire

Protective coverings

The efficiency and service of insulation is directly

dependent upon its protection from moisture entry andmechanical and chemical damage Choices of jacketing

materials are based upon the mechanical chemical

thermal and moisture conditions of the installation

as well as cost and appearance requirements The

basic function of the weather protection is to protect

the insulation from rain snow sleet wind solar

radiation atmospheric contamination and mechanical

damage With this definition in mind several service

requirements must be considered

PIPING INSULATION

For domestic hot water piping with smaller diameters

insulation pipe sections which are covered withaluminium foil are ideal Pipe sections with a facing

have a self-adhesive overlap in a longitudinal joint

to ensure perfect enclosure of a pipe section It is

recommended to secure pipe sections by an aluminium

tape or by galvanized wire transversely They are usually

knotted three times per meter more for pipe sections

with higher diameter Higher diameters should be

secured either by wire or by metal band (at least two

bands per meter)

Pipings with bigger diameters are most commonly

insulated by lamella mats Orstech LSP (stone woolinsulation) or Isover ML-3 (glass wool insulation)

eventually by wired mats Orstech DP (especially for higher

temperatures) Lamella and wired mats are also suitable

for appliances and vessels (both ends and cylindrical

parts) residential heating systems and air ducts

Internal mechanical forces ndash expansion and contraction

of the pipe or vessel must be considered because the

resulting forces are transferred to the external surface ofthe weather barrier Ability to slide elongate or contract

must be provided

External mechanical forces ndash mechanical abuse (ie

tools being dropped abrasion from wind-driven sand

personnel walking on the system) inflicted on a pipe or

vessel needs to be considered in design This may affect

insulation type as well as the weather barrier jacketing

type

Chemical resistance Some industrial environments may

have airborne or spilled corrosive agents that accumulate

on the weather barrier and chemically attack the pipe or

vessel jacketing Elements that create corrosive issues

must be well understood and accounted for Insulation

design of coastal facilities should account for chloride

attack

Galvanic corrosion Contacts between two different

types of metal must be considered for galvanic corrosion

potential Similarly water can act as an electrolyte and

galvanic corrosion can occur because of the differentpotential of the pipe and vessel and a metal jacketing

Materials used as weather barriers for insulation

Typical metal jacketing materials bare aluminium coated

aluminium stainless steel painted steel galvanized steel

aluminium-zinc coated steel

Typical polymeric jacketing materials polyvinyl chloride

(PVC) polyvinyliedene chloride (PVDC) polyisobutylene

multiple-layer composite materials (eg polymericfoil

mesh laminates) fabrics (silicone-impregnated fibreglass)

Fittings valves

Insulation of fittings valves flanges and couplings is

the most time consuming and often expensive aspectof commercial and industrial insulation But it is crucial

to insulate also these parts properly otherwise most of

energy will be transported by these thermal bridges For

example for 200 degC medium heat loss of one uninsulated

valve corresponds to one meter of uninsulated pipe or

ten meters of uninsulated pipe

Fittings are items used to change size direction of flow

level or assembly of piping They may be of the screwed

sweat or welded types Valves are any of various devices

that regulate liquid or gas flow and they may be of the

screwed sweated flanged or welded types Flanges areprotruding rims and edges of the screwed or sweated

type used with fittings valves couplings etc And finally

mechanical couplings are devices used in assembly of

piping Screwed and flanged connections on fittings

valves couplings etc usually require oversized insulation

applications to compensate for the protrusions

Minimum spacing between pipes and

constructions

It is essential to ensure sufficient space between pipies

and between a pipe and a wall (minimally 100 mm)

Otherwise there is a great danger of creating a zone withalmost no cenvenction The result can be too high surface

temperature (needed personal protection against burn)

or possibility of condensation on cold piping Besides

mounting would have been more difficult

DUCTING INSULATION

Isover products are designed to provide high levels of

thermal acoustic and fire protection insulation in HVACductwork applications such as rectangular flat oval and

circular ductwork

The most suitable insulation materials for ducts are

felts KLIMAROL with aluminium foil facing lamella mats

Orstech LSP or Isover ML-3 wired mats Orstech DP or

slabs Orstech H with aluminium foil facing

Duct insulation mounting

Insulation is mostly fixed to the duct by welded pinsWhen using Orstech H slabs with aluminium facing all

the joints shall be sealed with aluminium tape If a steel

clamping band is used it is necessary to use thin-walled

steel L-profiles to avoid trimming of the insulation If

using Orstech slabs without aluminium facing or Orstech

DP wired mats proper jacketing shall be made (the most

suitable is metal steel jacketing)

FIRE PROTECTION OF VENTILATION DUCT

Description

It is vital to develop safe durable and reliable solutions

for ventilation systems as fire can easily spread from the

point of origin via ductwork Isover meets the highest

standards for fire protection providing excellent fire

resistance and top-rated reaction to fire performance

Rectangular ducts shall be insulated by Orstech 65 H

slabs with 40 mm thickness (60 mm for fire resistance EI

60 for a horizontal duct) circular ducts shall be insulated

by Orstech LSP PYRO lamella mats with 50 mm thickness

By these solutions fire resistances EI 15 30 45 and 60 S

have been certified to comply with EN 1366-1

Orstech system with fire resistance has been proven to

meet the requirements of all possible scenarios for fire

from the outside The scenarios can be identified by duct

orientation and duct shape (see table below) Horizontal

ducts normally serve one floor of a building Vertical

ducts normally serve between floors of a building All

scenarios have been done only with one layer Insulation

is fixed to a duct by welded pins Such solution is time

and material saving

Metal ductworkThe steel duct is constructed in sections of galvanised

steel sheet or stainless steel sheet minimum 08 mm thick

(standard duct sheeting for rectangular ducts specified

in DIN 24190 for circular ducts in DIN 24145) Maximum

duct size for which classification protocol is valid is 1250

mm (width) x 1000 mm (height) for rectangular duct or

diameter up to 1000 mm for a circular duct

At each cross joint flanges are fastened to the duct

with spot welds at 150 mm nominal centres

Use a ceramic tape gasket and fire-stopping mastic

between the flanges to seal the joints

Flanges are bolted together with an M10 steel nut

and bolt at each corner

Fasten the flanges together with steel clamps with

bolts M8 (see the figure) in quantity of 3 clamps per 1

meter of the flange length

Drop rods and hangers

Rectangular ducts are suspended by threaded rods and

channel section bearers A duct shall be hung with asuspension system which is independently fire rated

according to EN 1363-1 Certificated suspension system

MUPRO is recommended for the purpose Each steel

hanger consists of two threaded drop rods minimum

M10 and a channel section bearer 3840 mm Fasten

the bearer to the drop rods using hexagonal nuts and

washers The drop rods can be positioned either inside

the insulation material or outside If drop rods are outside

there is no need to insulate them separately The bearers

are positioned inside the insulation material

Circular ducts are suspended by MUumlPRO steel hangerswhich consist of two threaded drop rods minimum

M10 and a two-part industrial circular band The ends

of each band section are bent outwards Fasten the band

sections together and attach them to the drop rods with

hexagonal nuts and washers Place these hangers inside

the insulation The rods do not need to be protected by

insulation

When fixing them to a concrete construction use all-

steel expanding anchors to fasten the threaded rod

hangers to concrete soffits The anchors should penetrate

the concrete by at least 60 mm When fixing to a steel

supporting construction drill a hole through the steel

member allowing the drop rod to be supported by a steel

nut and washer above If a clamp type fixing is used the

clamp must be steel suitable for the purpose It should

pass around the steel member and be fastened back on

itself Clamps that rely on friction to hold them in place

are not suitable

Insulation

Rectangular ducts are insulated by Orstech 65 H slabs

(with apparent density 65 kgm3 and with one-sidedaluminium foil facing) with 40 mm thickness (60 mm

for fire resistance EI 60 for a horizontal duct) Circular

ducts are insulated by lamella mats Orstech LSP PYRO

with 50 mm thickness Insulation slabs (lamella mats)

need to be cut to fit the duct as tightly as possible the

insulation may need to be cut to fit around flanged duct

joints Install the insulation so that one slab (lamella

mat) is adjacent and tightly fitted against the other No

gaps must be present between butt joints of insulation

Insulation can be easily cut with a standard laggers knife

There is no need for adhesive on joints All the joints shall

be sealed by aluminium tape For rectangular ducts in theposition of flange the slabs are snick first 15 mm of the

thickness to avoid lifting of the slabs Butt joints should

be positioned out of flanges Fire protective insulation for

circular ducts does not require usage of a wire net mesh

on the outer side of insulation

Stud welded pins

The insulation is fixed to the duct using steel pins 27 mm

to 3 mm nominal diameter and spring steel washers

minimum 30 mm diameter The length of pin should

be equal to the insulation thickness The orientational

number of pins is 16 piecesm2 for rectangular ducts and14 piecesm2 for circular ducts

Recommended distance from duct edges and joints is

80 mm 50 mm from flanges

Wallfloor penetration

At wallfloor penetration one must insure the same fire

resistance of ventilation duct as has the fire separation

to avoid the spreading of fire from one compartment to

other via a duct This is possible by two basic principles

or their combinations - install a fire damper at the

penetration point or use insulation with fire resistancewhere the crucial thing is the fire-stopping The fire-

stopping is from the second insulation layer with the

width of 150 mm from both side of fire separation

The same general principle is used for both rectangular

and circular ducts regardless of orientation Place

the duct in the penetration of the construction with

approximately 10 mm gap between insulated duct and

opening Before installing the fire-stopping with the

same insulation thickness as is used for the first layer

pack the space between the duct and partition with

as many pieces of insulation as possible Ensure tight

compression in order to completely fill the opening This

must be done because system ORSTECH Protect does

not require stiffeners inside the duct Then install thesecond insulation layer so that it is adjacent and tightly

fitted against the penetration The insulation must be

cut leaving excess length so that it exerts some pressure

between the penetration and the last fitted piece of

insulation

The second layer is fixed by welded pins with length

equal to double insulation thickness The second layer for

circular ducts (lamella mats) is clamped with 1-2 wires

with a diameter 16 mm Then the insulation is secured

to the duct by welded pins

A inovative solution is the considerable simplification of

a fire-stopping concept There is no need to use any kind

of stiffener either inside or outside of the duct A great

advantage is to mount the whole ventilation section

at once and the wall itself can be placed anywhere

Therefore the position variability of fire separation is

provided No glue or mastic is needed at wallfloor

penetrations

Fire classification

ORSTECH Protect insulation with fire resistance has

been tested by the fire testing laboratory Pavus as an

authorised body AO 216 Classification protocols on the

request

Fire protection system ORSTECH Protect has been tested

in accordance with EN 1366-1 Maximum size for the

rectangular duct is 1250 x 1000 mm and for the circular

duct up to diameter 1000 mm If a duct has bigger

dimensions the certificate connected to the standard

cannot be used

capabilities

for retrofitting purposes

Insulation is usually fixed by mechanical fasteners - by

studs or pins Spacing between them is dependent on the

design of the vessel its surface temperature fire hazard

potential involved and presumptive loading Each slab

should be fixed by minimally two pins

BOILER INSULATIONInsulations for boilers kettles and ovens are one of

the most demanding applications in industry because

these units are operating at very high temperatures

Good insulation not only saves energy considerably but

the main purpose is personal protection against burn

According to the surface shape and temperature are used

either slabs with higher densities Orstech 65 to 110 (for

boilers with flat surfaces) or wired mats Orstech DP 65 to

DP 100 (for boilers with cylindrical parts)

Boiler walls are exposed to very high temperatures

(usually around 500 or 600 degC) Therefore it is essential

to use mechanical fasteners for the fixing of insulation

to the surface Insulation for boilers is done in at least

two layers each layer must be staggered when applied

Each layer must be secured in place before the next is

applied A product with high density should be placed as

the first layer because it has a higher maximum surface

temperature (higher resistance against high operating

temperatures) and better insulation performace than

products with lower densities

CHIMNEY INSULATION

Insulations for prefabricated chimneys are directly

supplied by producers of such systems In cooperation

with specialized wholesale companies we offer slabs

with multi-plate stripes which allow easy and perfect

application for prefabricated chimneys suitable both

for stainless steel chimney liners as well as with other

brands of chimney lining systems The main advantage

is the time saving during the installation in comparison

with the use of lamella mats and horizontal orientation

of fibres (better thermal conductivity) Insulation

dimensions ie thickness of slabs and groove dimensions

dependent on the chimney diameter are supplied

according to customer needs

TECHNOLOGICAL APPLIANCEINSULATIONWhere big quantities of energy is used eg within

petrochemical paper and pulp industries thermal

insulation is necessary in order to reduce expensive

energy losses Tanks vessels exhausts exchangers

and technological piping are appliances that are often

working at high temperatures Good insulation will save

energy considerably which will benefit the environment

and keep the working costs down At the same time

the insulation will reduce temperature fall which could

disturb the production process

Proper insulation can be chosen in accordance with

dimension surface temperature the manner of fixing

and requirements for jacketing For pipes and cylindrical

parts are used lamella mats Orstech LSP H and Isover

ML-3 (only for temperatures up to 250 degC) or wired mats

Orstech DP For appliances and vessels with rectangular

shapes Orstech slabs are suitable (type according to a

surface temperature) Slabs can have aluminium facing

If insulation is done in more than one layer each layer

is staggered when applied Each layer must be secured

in place before the next is applied The decision to use

multiple layers may be made for one or more of the

following reasons

GENERAL RULES FOR USING ISOVER INSULATIONS

Between insulated piping sufficient distances must

be kept

Valves should be placed without needing to go on theinsulated pipes when handling them

Spindle of valves should not be installed in an upward

direction to avoid water leakage into the insulation

Surfaces before insulating must be clean and dry It

is not possible to insulate wet or frostbitten surfaces

which may later cause damages of insulation or

insulated surfaces

Dirt and rust must be rubbed down from untreated

carbon steels

Smear and oils must be removed by detergents or

solvents from insulated surfaces

Stainless steel surfaces must not be cleaned by

detergents or solvents with chloride content They

may be cleaned only by stainless steel brushes

Chloride solution attacks stainless steel surface and

causes stress corrosion cracking in the material With

increasing surface temperature the danger of stress

corrosion cracking is raised

Piping and equipment from stainless steel can be

insulated only by mineral wool insulation in AS

quality Such material can have maximum content

of chloride ions of 10 mg in 1 kg of the insulation

material

It is necessary to avoid contact of metals which can

cause galvanic corrosion (Cu-Zn Fe-Al)For operating temperatures higher than 600 degC

aluminium jacketing should not be used

Self-tapping screw bold or rivet should be from the

same material as the jacketing

Surfaces with temperatures higher than 500 degC

should be insulated by more insulation layers in a

way that each layer has a different apparent density

Material with higher density insulates better under

higher temperatures than material with lower

density therefore insulation with higher density is

placed closer to the hot side Under low operating

temperatures thermal performance is almost equalSafety working principles must be kept for insulation

assembly

Isover products are packed into PE foil They must be

transported in covered vehicles under such conditions

to avoid moistening or other degradation They must

be stored in covered places

Wired mats

After the cutting of needed length the wired mat shall

be tightly wrapped on the pipe Wired matsrsquo butt jointsshould be in close contact to each other to ensure no

gaps between mats For multiple layer construction

each layer is staggered when applied Each layer must

be secured in place before the next is applied Individual

mats are bound together with a wire with minimal 07

mm thickness Alternatively wired hook or stainless

steel bands (with minimum width of 10 mm) can be

used Maximum distance between hooks is 150 mm

The decision to use multiple layers may be made for one

or more of the following reasons

to provide compensation for pipe expansion andcontraction

to reduce heat flow by staggering joints thus creating

a more thermally efficient installation

to achieve thickness in excess of manufacturersrsquo

capabilities

for retrofitting purposes

Lamella mats

Lamella mats Orstech LSP H consist of mineral wool

lamellas which have been glued to aluminium foil

reinforced with a glass fibre grid and these fibres are

predominantly perpendicular to the surface of themat Compressive strength but thermal conductivity

too are increased compared to mats with a fibre

orientation parallel to the surface (wired mats) Due

to its compressive strength resistance they have less

demands for undeconstruction (less thermal bridges)

in comparison with wired mats Temporary securing in

place is done by aluminium tapes final fixing shall be

done by a baling wire

Protective coverings

The efficiency and service of insulation is directly

dependent upon its protection from moisture entry andmechanical and chemical damage Choices of jacketing

materials are based upon the mechanical chemical

thermal and moisture conditions of the installation

as well as cost and appearance requirements The

basic function of the weather protection is to protect

the insulation from rain snow sleet wind solar

radiation atmospheric contamination and mechanical

damage With this definition in mind several service

requirements must be considered

PIPING INSULATION

For domestic hot water piping with smaller diameters

insulation pipe sections which are covered withaluminium foil are ideal Pipe sections with a facing

have a self-adhesive overlap in a longitudinal joint

to ensure perfect enclosure of a pipe section It is

recommended to secure pipe sections by an aluminium

tape or by galvanized wire transversely They are usually

knotted three times per meter more for pipe sections

with higher diameter Higher diameters should be

secured either by wire or by metal band (at least two

bands per meter)

Pipings with bigger diameters are most commonly

insulated by lamella mats Orstech LSP (stone woolinsulation) or Isover ML-3 (glass wool insulation)

eventually by wired mats Orstech DP (especially for higher

temperatures) Lamella and wired mats are also suitable

for appliances and vessels (both ends and cylindrical

parts) residential heating systems and air ducts

Internal mechanical forces ndash expansion and contraction

of the pipe or vessel must be considered because the

resulting forces are transferred to the external surface ofthe weather barrier Ability to slide elongate or contract

must be provided

External mechanical forces ndash mechanical abuse (ie

tools being dropped abrasion from wind-driven sand

personnel walking on the system) inflicted on a pipe or

vessel needs to be considered in design This may affect

insulation type as well as the weather barrier jacketing

type

Chemical resistance Some industrial environments may

have airborne or spilled corrosive agents that accumulate

on the weather barrier and chemically attack the pipe or

vessel jacketing Elements that create corrosive issues

must be well understood and accounted for Insulation

design of coastal facilities should account for chloride

attack

Galvanic corrosion Contacts between two different

types of metal must be considered for galvanic corrosion

potential Similarly water can act as an electrolyte and

galvanic corrosion can occur because of the differentpotential of the pipe and vessel and a metal jacketing

Materials used as weather barriers for insulation

Typical metal jacketing materials bare aluminium coated

aluminium stainless steel painted steel galvanized steel

aluminium-zinc coated steel

Typical polymeric jacketing materials polyvinyl chloride

(PVC) polyvinyliedene chloride (PVDC) polyisobutylene

multiple-layer composite materials (eg polymericfoil

mesh laminates) fabrics (silicone-impregnated fibreglass)

Fittings valves

Insulation of fittings valves flanges and couplings is

the most time consuming and often expensive aspectof commercial and industrial insulation But it is crucial

to insulate also these parts properly otherwise most of

energy will be transported by these thermal bridges For

example for 200 degC medium heat loss of one uninsulated

valve corresponds to one meter of uninsulated pipe or

ten meters of uninsulated pipe

Fittings are items used to change size direction of flow

level or assembly of piping They may be of the screwed

sweat or welded types Valves are any of various devices

that regulate liquid or gas flow and they may be of the

screwed sweated flanged or welded types Flanges areprotruding rims and edges of the screwed or sweated

type used with fittings valves couplings etc And finally

mechanical couplings are devices used in assembly of

piping Screwed and flanged connections on fittings

valves couplings etc usually require oversized insulation

applications to compensate for the protrusions

Minimum spacing between pipes and

constructions

It is essential to ensure sufficient space between pipies

and between a pipe and a wall (minimally 100 mm)

Otherwise there is a great danger of creating a zone withalmost no cenvenction The result can be too high surface

temperature (needed personal protection against burn)

or possibility of condensation on cold piping Besides

mounting would have been more difficult

DUCTING INSULATION

Isover products are designed to provide high levels of

thermal acoustic and fire protection insulation in HVACductwork applications such as rectangular flat oval and

circular ductwork

The most suitable insulation materials for ducts are

felts KLIMAROL with aluminium foil facing lamella mats

Orstech LSP or Isover ML-3 wired mats Orstech DP or

slabs Orstech H with aluminium foil facing

Duct insulation mounting

Insulation is mostly fixed to the duct by welded pinsWhen using Orstech H slabs with aluminium facing all

the joints shall be sealed with aluminium tape If a steel

clamping band is used it is necessary to use thin-walled

steel L-profiles to avoid trimming of the insulation If

using Orstech slabs without aluminium facing or Orstech

DP wired mats proper jacketing shall be made (the most

suitable is metal steel jacketing)

FIRE PROTECTION OF VENTILATION DUCT

Description

It is vital to develop safe durable and reliable solutions

for ventilation systems as fire can easily spread from the

point of origin via ductwork Isover meets the highest

standards for fire protection providing excellent fire

resistance and top-rated reaction to fire performance

Rectangular ducts shall be insulated by Orstech 65 H

slabs with 40 mm thickness (60 mm for fire resistance EI

60 for a horizontal duct) circular ducts shall be insulated

by Orstech LSP PYRO lamella mats with 50 mm thickness

By these solutions fire resistances EI 15 30 45 and 60 S

have been certified to comply with EN 1366-1

Orstech system with fire resistance has been proven to

meet the requirements of all possible scenarios for fire

from the outside The scenarios can be identified by duct

orientation and duct shape (see table below) Horizontal

ducts normally serve one floor of a building Vertical

ducts normally serve between floors of a building All

scenarios have been done only with one layer Insulation

is fixed to a duct by welded pins Such solution is time

and material saving

Metal ductworkThe steel duct is constructed in sections of galvanised

steel sheet or stainless steel sheet minimum 08 mm thick

(standard duct sheeting for rectangular ducts specified

in DIN 24190 for circular ducts in DIN 24145) Maximum

duct size for which classification protocol is valid is 1250

mm (width) x 1000 mm (height) for rectangular duct or

diameter up to 1000 mm for a circular duct

At each cross joint flanges are fastened to the duct

with spot welds at 150 mm nominal centres

Use a ceramic tape gasket and fire-stopping mastic

between the flanges to seal the joints

Flanges are bolted together with an M10 steel nut

and bolt at each corner

Fasten the flanges together with steel clamps with

bolts M8 (see the figure) in quantity of 3 clamps per 1

meter of the flange length

Drop rods and hangers

Rectangular ducts are suspended by threaded rods and

channel section bearers A duct shall be hung with asuspension system which is independently fire rated

according to EN 1363-1 Certificated suspension system

MUPRO is recommended for the purpose Each steel

hanger consists of two threaded drop rods minimum

M10 and a channel section bearer 3840 mm Fasten

the bearer to the drop rods using hexagonal nuts and

washers The drop rods can be positioned either inside

the insulation material or outside If drop rods are outside

there is no need to insulate them separately The bearers

are positioned inside the insulation material

Circular ducts are suspended by MUumlPRO steel hangerswhich consist of two threaded drop rods minimum

M10 and a two-part industrial circular band The ends

of each band section are bent outwards Fasten the band

sections together and attach them to the drop rods with

hexagonal nuts and washers Place these hangers inside

the insulation The rods do not need to be protected by

insulation

When fixing them to a concrete construction use all-

steel expanding anchors to fasten the threaded rod

hangers to concrete soffits The anchors should penetrate

the concrete by at least 60 mm When fixing to a steel

supporting construction drill a hole through the steel

member allowing the drop rod to be supported by a steel

nut and washer above If a clamp type fixing is used the

clamp must be steel suitable for the purpose It should

pass around the steel member and be fastened back on

itself Clamps that rely on friction to hold them in place

are not suitable

Insulation

Rectangular ducts are insulated by Orstech 65 H slabs

(with apparent density 65 kgm3 and with one-sidedaluminium foil facing) with 40 mm thickness (60 mm

for fire resistance EI 60 for a horizontal duct) Circular

ducts are insulated by lamella mats Orstech LSP PYRO

with 50 mm thickness Insulation slabs (lamella mats)

need to be cut to fit the duct as tightly as possible the

insulation may need to be cut to fit around flanged duct

joints Install the insulation so that one slab (lamella

mat) is adjacent and tightly fitted against the other No

gaps must be present between butt joints of insulation

Insulation can be easily cut with a standard laggers knife

There is no need for adhesive on joints All the joints shall

be sealed by aluminium tape For rectangular ducts in theposition of flange the slabs are snick first 15 mm of the

thickness to avoid lifting of the slabs Butt joints should

be positioned out of flanges Fire protective insulation for

circular ducts does not require usage of a wire net mesh

on the outer side of insulation

Stud welded pins

The insulation is fixed to the duct using steel pins 27 mm

to 3 mm nominal diameter and spring steel washers

minimum 30 mm diameter The length of pin should

be equal to the insulation thickness The orientational

number of pins is 16 piecesm2 for rectangular ducts and14 piecesm2 for circular ducts

Recommended distance from duct edges and joints is

80 mm 50 mm from flanges

Wallfloor penetration

At wallfloor penetration one must insure the same fire

resistance of ventilation duct as has the fire separation

to avoid the spreading of fire from one compartment to

other via a duct This is possible by two basic principles

or their combinations - install a fire damper at the

penetration point or use insulation with fire resistancewhere the crucial thing is the fire-stopping The fire-

stopping is from the second insulation layer with the

width of 150 mm from both side of fire separation

The same general principle is used for both rectangular

and circular ducts regardless of orientation Place

the duct in the penetration of the construction with

approximately 10 mm gap between insulated duct and

opening Before installing the fire-stopping with the

same insulation thickness as is used for the first layer

pack the space between the duct and partition with

as many pieces of insulation as possible Ensure tight

compression in order to completely fill the opening This

must be done because system ORSTECH Protect does

not require stiffeners inside the duct Then install thesecond insulation layer so that it is adjacent and tightly

fitted against the penetration The insulation must be

cut leaving excess length so that it exerts some pressure

between the penetration and the last fitted piece of

insulation

The second layer is fixed by welded pins with length

equal to double insulation thickness The second layer for

circular ducts (lamella mats) is clamped with 1-2 wires

with a diameter 16 mm Then the insulation is secured

to the duct by welded pins

A inovative solution is the considerable simplification of

a fire-stopping concept There is no need to use any kind

of stiffener either inside or outside of the duct A great

advantage is to mount the whole ventilation section

at once and the wall itself can be placed anywhere

Therefore the position variability of fire separation is

provided No glue or mastic is needed at wallfloor

penetrations

Fire classification

ORSTECH Protect insulation with fire resistance has

been tested by the fire testing laboratory Pavus as an

authorised body AO 216 Classification protocols on the

request

Fire protection system ORSTECH Protect has been tested

in accordance with EN 1366-1 Maximum size for the

rectangular duct is 1250 x 1000 mm and for the circular

duct up to diameter 1000 mm If a duct has bigger

dimensions the certificate connected to the standard

cannot be used

capabilities

for retrofitting purposes

Insulation is usually fixed by mechanical fasteners - by

studs or pins Spacing between them is dependent on the

design of the vessel its surface temperature fire hazard

potential involved and presumptive loading Each slab

should be fixed by minimally two pins

BOILER INSULATIONInsulations for boilers kettles and ovens are one of

the most demanding applications in industry because

these units are operating at very high temperatures

Good insulation not only saves energy considerably but

the main purpose is personal protection against burn

According to the surface shape and temperature are used

either slabs with higher densities Orstech 65 to 110 (for

boilers with flat surfaces) or wired mats Orstech DP 65 to

DP 100 (for boilers with cylindrical parts)

Boiler walls are exposed to very high temperatures

(usually around 500 or 600 degC) Therefore it is essential

to use mechanical fasteners for the fixing of insulation

to the surface Insulation for boilers is done in at least

two layers each layer must be staggered when applied

Each layer must be secured in place before the next is

applied A product with high density should be placed as

the first layer because it has a higher maximum surface

temperature (higher resistance against high operating

temperatures) and better insulation performace than

products with lower densities

CHIMNEY INSULATION

Insulations for prefabricated chimneys are directly

supplied by producers of such systems In cooperation

with specialized wholesale companies we offer slabs

with multi-plate stripes which allow easy and perfect

application for prefabricated chimneys suitable both

for stainless steel chimney liners as well as with other

brands of chimney lining systems The main advantage

is the time saving during the installation in comparison

with the use of lamella mats and horizontal orientation

of fibres (better thermal conductivity) Insulation

dimensions ie thickness of slabs and groove dimensions

dependent on the chimney diameter are supplied

according to customer needs

For non-prefabricated chimneys are mostly used wired

mats Orstech DP or slabs Orstech 90 or 110 (for chimneys

with rectangular cross-section)

TECHNOLOGICAL APPLIANCEINSULATIONWhere big quantities of energy is used eg within

petrochemical paper and pulp industries thermal

insulation is necessary in order to reduce expensive

energy losses Tanks vessels exhausts exchangers

and technological piping are appliances that are often

working at high temperatures Good insulation will save

energy considerably which will benefit the environment

and keep the working costs down At the same time

the insulation will reduce temperature fall which could

disturb the production process

Proper insulation can be chosen in accordance with

dimension surface temperature the manner of fixing

and requirements for jacketing For pipes and cylindrical

parts are used lamella mats Orstech LSP H and Isover

ML-3 (only for temperatures up to 250 degC) or wired mats

Orstech DP For appliances and vessels with rectangular

shapes Orstech slabs are suitable (type according to a

surface temperature) Slabs can have aluminium facing

If insulation is done in more than one layer each layer

is staggered when applied Each layer must be secured

in place before the next is applied The decision to use

multiple layers may be made for one or more of the

following reasons

Wired mats

After the cutting of needed length the wired mat shall

be tightly wrapped on the pipe Wired matsrsquo butt jointsshould be in close contact to each other to ensure no

gaps between mats For multiple layer construction

each layer is staggered when applied Each layer must

be secured in place before the next is applied Individual

mats are bound together with a wire with minimal 07

mm thickness Alternatively wired hook or stainless

steel bands (with minimum width of 10 mm) can be

used Maximum distance between hooks is 150 mm

The decision to use multiple layers may be made for one

or more of the following reasons

to provide compensation for pipe expansion andcontraction

to reduce heat flow by staggering joints thus creating

a more thermally efficient installation

to achieve thickness in excess of manufacturersrsquo

capabilities

for retrofitting purposes

Lamella mats

Lamella mats Orstech LSP H consist of mineral wool

lamellas which have been glued to aluminium foil

reinforced with a glass fibre grid and these fibres are

predominantly perpendicular to the surface of themat Compressive strength but thermal conductivity

too are increased compared to mats with a fibre

orientation parallel to the surface (wired mats) Due

to its compressive strength resistance they have less

demands for undeconstruction (less thermal bridges)

in comparison with wired mats Temporary securing in

place is done by aluminium tapes final fixing shall be

done by a baling wire

Protective coverings

The efficiency and service of insulation is directly

dependent upon its protection from moisture entry andmechanical and chemical damage Choices of jacketing

materials are based upon the mechanical chemical

thermal and moisture conditions of the installation

as well as cost and appearance requirements The

basic function of the weather protection is to protect

the insulation from rain snow sleet wind solar

radiation atmospheric contamination and mechanical

damage With this definition in mind several service

requirements must be considered

PIPING INSULATION

For domestic hot water piping with smaller diameters

insulation pipe sections which are covered withaluminium foil are ideal Pipe sections with a facing

have a self-adhesive overlap in a longitudinal joint

to ensure perfect enclosure of a pipe section It is

recommended to secure pipe sections by an aluminium

tape or by galvanized wire transversely They are usually

knotted three times per meter more for pipe sections

with higher diameter Higher diameters should be

secured either by wire or by metal band (at least two

bands per meter)

Pipings with bigger diameters are most commonly

insulated by lamella mats Orstech LSP (stone woolinsulation) or Isover ML-3 (glass wool insulation)

eventually by wired mats Orstech DP (especially for higher

temperatures) Lamella and wired mats are also suitable

for appliances and vessels (both ends and cylindrical

parts) residential heating systems and air ducts

Internal mechanical forces ndash expansion and contraction

of the pipe or vessel must be considered because the

resulting forces are transferred to the external surface ofthe weather barrier Ability to slide elongate or contract

must be provided

External mechanical forces ndash mechanical abuse (ie

tools being dropped abrasion from wind-driven sand

personnel walking on the system) inflicted on a pipe or

vessel needs to be considered in design This may affect

insulation type as well as the weather barrier jacketing

type

Chemical resistance Some industrial environments may

have airborne or spilled corrosive agents that accumulate

on the weather barrier and chemically attack the pipe or

vessel jacketing Elements that create corrosive issues

must be well understood and accounted for Insulation

design of coastal facilities should account for chloride

attack

Galvanic corrosion Contacts between two different

types of metal must be considered for galvanic corrosion

potential Similarly water can act as an electrolyte and

galvanic corrosion can occur because of the differentpotential of the pipe and vessel and a metal jacketing

Materials used as weather barriers for insulation

Typical metal jacketing materials bare aluminium coated

aluminium stainless steel painted steel galvanized steel

aluminium-zinc coated steel

Typical polymeric jacketing materials polyvinyl chloride

(PVC) polyvinyliedene chloride (PVDC) polyisobutylene

multiple-layer composite materials (eg polymericfoil

mesh laminates) fabrics (silicone-impregnated fibreglass)

Fittings valves

Insulation of fittings valves flanges and couplings is

the most time consuming and often expensive aspectof commercial and industrial insulation But it is crucial

to insulate also these parts properly otherwise most of

energy will be transported by these thermal bridges For

example for 200 degC medium heat loss of one uninsulated

valve corresponds to one meter of uninsulated pipe or

ten meters of uninsulated pipe

Fittings are items used to change size direction of flow

level or assembly of piping They may be of the screwed

sweat or welded types Valves are any of various devices

that regulate liquid or gas flow and they may be of the

screwed sweated flanged or welded types Flanges areprotruding rims and edges of the screwed or sweated

type used with fittings valves couplings etc And finally

mechanical couplings are devices used in assembly of

piping Screwed and flanged connections on fittings

valves couplings etc usually require oversized insulation

applications to compensate for the protrusions

Minimum spacing between pipes and

constructions

It is essential to ensure sufficient space between pipies

and between a pipe and a wall (minimally 100 mm)

Otherwise there is a great danger of creating a zone withalmost no cenvenction The result can be too high surface

temperature (needed personal protection against burn)

or possibility of condensation on cold piping Besides

mounting would have been more difficult

DUCTING INSULATION

Isover products are designed to provide high levels of

thermal acoustic and fire protection insulation in HVACductwork applications such as rectangular flat oval and

circular ductwork

The most suitable insulation materials for ducts are

felts KLIMAROL with aluminium foil facing lamella mats

Orstech LSP or Isover ML-3 wired mats Orstech DP or

slabs Orstech H with aluminium foil facing

Duct insulation mounting

Insulation is mostly fixed to the duct by welded pinsWhen using Orstech H slabs with aluminium facing all

the joints shall be sealed with aluminium tape If a steel

clamping band is used it is necessary to use thin-walled

steel L-profiles to avoid trimming of the insulation If

using Orstech slabs without aluminium facing or Orstech

DP wired mats proper jacketing shall be made (the most

suitable is metal steel jacketing)

FIRE PROTECTION OF VENTILATION DUCT

Description

It is vital to develop safe durable and reliable solutions

for ventilation systems as fire can easily spread from the

point of origin via ductwork Isover meets the highest

standards for fire protection providing excellent fire

resistance and top-rated reaction to fire performance

Rectangular ducts shall be insulated by Orstech 65 H

slabs with 40 mm thickness (60 mm for fire resistance EI

60 for a horizontal duct) circular ducts shall be insulated

by Orstech LSP PYRO lamella mats with 50 mm thickness

By these solutions fire resistances EI 15 30 45 and 60 S

have been certified to comply with EN 1366-1

Orstech system with fire resistance has been proven to

meet the requirements of all possible scenarios for fire

from the outside The scenarios can be identified by duct

orientation and duct shape (see table below) Horizontal

ducts normally serve one floor of a building Vertical

ducts normally serve between floors of a building All

scenarios have been done only with one layer Insulation

is fixed to a duct by welded pins Such solution is time

and material saving

Metal ductworkThe steel duct is constructed in sections of galvanised

steel sheet or stainless steel sheet minimum 08 mm thick

(standard duct sheeting for rectangular ducts specified

in DIN 24190 for circular ducts in DIN 24145) Maximum

duct size for which classification protocol is valid is 1250

mm (width) x 1000 mm (height) for rectangular duct or

diameter up to 1000 mm for a circular duct

At each cross joint flanges are fastened to the duct

with spot welds at 150 mm nominal centres

Use a ceramic tape gasket and fire-stopping mastic

between the flanges to seal the joints

Flanges are bolted together with an M10 steel nut

and bolt at each corner

Fasten the flanges together with steel clamps with

bolts M8 (see the figure) in quantity of 3 clamps per 1

meter of the flange length

Drop rods and hangers

Rectangular ducts are suspended by threaded rods and

channel section bearers A duct shall be hung with asuspension system which is independently fire rated

according to EN 1363-1 Certificated suspension system

MUPRO is recommended for the purpose Each steel

hanger consists of two threaded drop rods minimum

M10 and a channel section bearer 3840 mm Fasten

the bearer to the drop rods using hexagonal nuts and

washers The drop rods can be positioned either inside

the insulation material or outside If drop rods are outside

there is no need to insulate them separately The bearers

are positioned inside the insulation material

Circular ducts are suspended by MUumlPRO steel hangerswhich consist of two threaded drop rods minimum

M10 and a two-part industrial circular band The ends

of each band section are bent outwards Fasten the band

sections together and attach them to the drop rods with

hexagonal nuts and washers Place these hangers inside

the insulation The rods do not need to be protected by

insulation

When fixing them to a concrete construction use all-

steel expanding anchors to fasten the threaded rod

hangers to concrete soffits The anchors should penetrate

the concrete by at least 60 mm When fixing to a steel

supporting construction drill a hole through the steel

member allowing the drop rod to be supported by a steel

nut and washer above If a clamp type fixing is used the

clamp must be steel suitable for the purpose It should

pass around the steel member and be fastened back on

itself Clamps that rely on friction to hold them in place

are not suitable

Insulation

Rectangular ducts are insulated by Orstech 65 H slabs

(with apparent density 65 kgm3 and with one-sidedaluminium foil facing) with 40 mm thickness (60 mm

for fire resistance EI 60 for a horizontal duct) Circular

ducts are insulated by lamella mats Orstech LSP PYRO

with 50 mm thickness Insulation slabs (lamella mats)

need to be cut to fit the duct as tightly as possible the

insulation may need to be cut to fit around flanged duct

joints Install the insulation so that one slab (lamella

mat) is adjacent and tightly fitted against the other No

gaps must be present between butt joints of insulation

Insulation can be easily cut with a standard laggers knife

There is no need for adhesive on joints All the joints shall

be sealed by aluminium tape For rectangular ducts in theposition of flange the slabs are snick first 15 mm of the

thickness to avoid lifting of the slabs Butt joints should

be positioned out of flanges Fire protective insulation for

circular ducts does not require usage of a wire net mesh

on the outer side of insulation

Stud welded pins

The insulation is fixed to the duct using steel pins 27 mm

to 3 mm nominal diameter and spring steel washers

minimum 30 mm diameter The length of pin should

be equal to the insulation thickness The orientational

number of pins is 16 piecesm2 for rectangular ducts and14 piecesm2 for circular ducts

Recommended distance from duct edges and joints is

80 mm 50 mm from flanges

Wallfloor penetration

At wallfloor penetration one must insure the same fire

resistance of ventilation duct as has the fire separation

to avoid the spreading of fire from one compartment to

other via a duct This is possible by two basic principles

or their combinations - install a fire damper at the

penetration point or use insulation with fire resistancewhere the crucial thing is the fire-stopping The fire-

stopping is from the second insulation layer with the

width of 150 mm from both side of fire separation

The same general principle is used for both rectangular

and circular ducts regardless of orientation Place

the duct in the penetration of the construction with

approximately 10 mm gap between insulated duct and

opening Before installing the fire-stopping with the

same insulation thickness as is used for the first layer

pack the space between the duct and partition with

as many pieces of insulation as possible Ensure tight

compression in order to completely fill the opening This

must be done because system ORSTECH Protect does

not require stiffeners inside the duct Then install thesecond insulation layer so that it is adjacent and tightly

fitted against the penetration The insulation must be

cut leaving excess length so that it exerts some pressure

between the penetration and the last fitted piece of

insulation

The second layer is fixed by welded pins with length

equal to double insulation thickness The second layer for

circular ducts (lamella mats) is clamped with 1-2 wires

with a diameter 16 mm Then the insulation is secured

to the duct by welded pins

A inovative solution is the considerable simplification of

a fire-stopping concept There is no need to use any kind

of stiffener either inside or outside of the duct A great

advantage is to mount the whole ventilation section

at once and the wall itself can be placed anywhere

Therefore the position variability of fire separation is

provided No glue or mastic is needed at wallfloor

penetrations

Fire classification

ORSTECH Protect insulation with fire resistance has

been tested by the fire testing laboratory Pavus as an

authorised body AO 216 Classification protocols on the

request

Fire protection system ORSTECH Protect has been tested

in accordance with EN 1366-1 Maximum size for the

rectangular duct is 1250 x 1000 mm and for the circular

duct up to diameter 1000 mm If a duct has bigger

dimensions the certificate connected to the standard

cannot be used

capabilities

for retrofitting purposes

Insulation is usually fixed by mechanical fasteners - by

studs or pins Spacing between them is dependent on the

design of the vessel its surface temperature fire hazard

potential involved and presumptive loading Each slab

should be fixed by minimally two pins

BOILER INSULATIONInsulations for boilers kettles and ovens are one of

the most demanding applications in industry because

these units are operating at very high temperatures

Good insulation not only saves energy considerably but

the main purpose is personal protection against burn

According to the surface shape and temperature are used

either slabs with higher densities Orstech 65 to 110 (for

boilers with flat surfaces) or wired mats Orstech DP 65 to

DP 100 (for boilers with cylindrical parts)

Boiler walls are exposed to very high temperatures

(usually around 500 or 600 degC) Therefore it is essential

to use mechanical fasteners for the fixing of insulation

to the surface Insulation for boilers is done in at least

two layers each layer must be staggered when applied

Each layer must be secured in place before the next is

applied A product with high density should be placed as

the first layer because it has a higher maximum surface

temperature (higher resistance against high operating

temperatures) and better insulation performace than

products with lower densities

CHIMNEY INSULATION

Insulations for prefabricated chimneys are directly

supplied by producers of such systems In cooperation

with specialized wholesale companies we offer slabs

with multi-plate stripes which allow easy and perfect

application for prefabricated chimneys suitable both

for stainless steel chimney liners as well as with other

brands of chimney lining systems The main advantage

is the time saving during the installation in comparison

with the use of lamella mats and horizontal orientation

of fibres (better thermal conductivity) Insulation

dimensions ie thickness of slabs and groove dimensions

dependent on the chimney diameter are supplied

according to customer needs

For non-prefabricated chimneys are mostly used wired

mats Orstech DP or slabs Orstech 90 or 110 (for chimneys

with rectangular cross-section)

TECHNOLOGICAL APPLIANCEINSULATIONWhere big quantities of energy is used eg within

petrochemical paper and pulp industries thermal

insulation is necessary in order to reduce expensive

energy losses Tanks vessels exhausts exchangers

and technological piping are appliances that are often

working at high temperatures Good insulation will save

energy considerably which will benefit the environment

and keep the working costs down At the same time

the insulation will reduce temperature fall which could

disturb the production process

Proper insulation can be chosen in accordance with

dimension surface temperature the manner of fixing

and requirements for jacketing For pipes and cylindrical

parts are used lamella mats Orstech LSP H and Isover

ML-3 (only for temperatures up to 250 degC) or wired mats

Orstech DP For appliances and vessels with rectangular

shapes Orstech slabs are suitable (type according to a

surface temperature) Slabs can have aluminium facing

If insulation is done in more than one layer each layer

is staggered when applied Each layer must be secured

in place before the next is applied The decision to use

multiple layers may be made for one or more of the

following reasons

Internal mechanical forces ndash expansion and contraction

of the pipe or vessel must be considered because the

resulting forces are transferred to the external surface ofthe weather barrier Ability to slide elongate or contract

must be provided

External mechanical forces ndash mechanical abuse (ie

tools being dropped abrasion from wind-driven sand

personnel walking on the system) inflicted on a pipe or

vessel needs to be considered in design This may affect

insulation type as well as the weather barrier jacketing

type

Chemical resistance Some industrial environments may

have airborne or spilled corrosive agents that accumulate

on the weather barrier and chemically attack the pipe or

vessel jacketing Elements that create corrosive issues

must be well understood and accounted for Insulation

design of coastal facilities should account for chloride

attack

Galvanic corrosion Contacts between two different

types of metal must be considered for galvanic corrosion

potential Similarly water can act as an electrolyte and

galvanic corrosion can occur because of the differentpotential of the pipe and vessel and a metal jacketing

Materials used as weather barriers for insulation

Typical metal jacketing materials bare aluminium coated

aluminium stainless steel painted steel galvanized steel

aluminium-zinc coated steel

Typical polymeric jacketing materials polyvinyl chloride

(PVC) polyvinyliedene chloride (PVDC) polyisobutylene

multiple-layer composite materials (eg polymericfoil

mesh laminates) fabrics (silicone-impregnated fibreglass)

Fittings valves

Insulation of fittings valves flanges and couplings is

the most time consuming and often expensive aspectof commercial and industrial insulation But it is crucial

to insulate also these parts properly otherwise most of

energy will be transported by these thermal bridges For

example for 200 degC medium heat loss of one uninsulated

valve corresponds to one meter of uninsulated pipe or

ten meters of uninsulated pipe

Fittings are items used to change size direction of flow

level or assembly of piping They may be of the screwed

sweat or welded types Valves are any of various devices

that regulate liquid or gas flow and they may be of the

screwed sweated flanged or welded types Flanges areprotruding rims and edges of the screwed or sweated

type used with fittings valves couplings etc And finally

mechanical couplings are devices used in assembly of

piping Screwed and flanged connections on fittings

valves couplings etc usually require oversized insulation

applications to compensate for the protrusions

Minimum spacing between pipes and

constructions

It is essential to ensure sufficient space between pipies

and between a pipe and a wall (minimally 100 mm)

Otherwise there is a great danger of creating a zone withalmost no cenvenction The result can be too high surface

temperature (needed personal protection against burn)

or possibility of condensation on cold piping Besides

mounting would have been more difficult

DUCTING INSULATION

Isover products are designed to provide high levels of

thermal acoustic and fire protection insulation in HVACductwork applications such as rectangular flat oval and

circular ductwork

The most suitable insulation materials for ducts are

felts KLIMAROL with aluminium foil facing lamella mats

Orstech LSP or Isover ML-3 wired mats Orstech DP or

slabs Orstech H with aluminium foil facing

Duct insulation mounting

Insulation is mostly fixed to the duct by welded pinsWhen using Orstech H slabs with aluminium facing all

the joints shall be sealed with aluminium tape If a steel

clamping band is used it is necessary to use thin-walled

steel L-profiles to avoid trimming of the insulation If

using Orstech slabs without aluminium facing or Orstech

DP wired mats proper jacketing shall be made (the most

suitable is metal steel jacketing)

FIRE PROTECTION OF VENTILATION DUCT

Description

It is vital to develop safe durable and reliable solutions

for ventilation systems as fire can easily spread from the

point of origin via ductwork Isover meets the highest

standards for fire protection providing excellent fire

resistance and top-rated reaction to fire performance

Rectangular ducts shall be insulated by Orstech 65 H

slabs with 40 mm thickness (60 mm for fire resistance EI

60 for a horizontal duct) circular ducts shall be insulated

by Orstech LSP PYRO lamella mats with 50 mm thickness

By these solutions fire resistances EI 15 30 45 and 60 S

have been certified to comply with EN 1366-1

Orstech system with fire resistance has been proven to

meet the requirements of all possible scenarios for fire

from the outside The scenarios can be identified by duct

orientation and duct shape (see table below) Horizontal

ducts normally serve one floor of a building Vertical

ducts normally serve between floors of a building All

scenarios have been done only with one layer Insulation

is fixed to a duct by welded pins Such solution is time

and material saving

Metal ductworkThe steel duct is constructed in sections of galvanised

steel sheet or stainless steel sheet minimum 08 mm thick

(standard duct sheeting for rectangular ducts specified

in DIN 24190 for circular ducts in DIN 24145) Maximum

duct size for which classification protocol is valid is 1250

mm (width) x 1000 mm (height) for rectangular duct or

diameter up to 1000 mm for a circular duct

At each cross joint flanges are fastened to the duct

with spot welds at 150 mm nominal centres

Use a ceramic tape gasket and fire-stopping mastic

between the flanges to seal the joints

Flanges are bolted together with an M10 steel nut

and bolt at each corner

Fasten the flanges together with steel clamps with

bolts M8 (see the figure) in quantity of 3 clamps per 1

meter of the flange length

Drop rods and hangers

Rectangular ducts are suspended by threaded rods and

channel section bearers A duct shall be hung with asuspension system which is independently fire rated

according to EN 1363-1 Certificated suspension system

MUPRO is recommended for the purpose Each steel

hanger consists of two threaded drop rods minimum

M10 and a channel section bearer 3840 mm Fasten

the bearer to the drop rods using hexagonal nuts and

washers The drop rods can be positioned either inside

the insulation material or outside If drop rods are outside

there is no need to insulate them separately The bearers

are positioned inside the insulation material

Circular ducts are suspended by MUumlPRO steel hangerswhich consist of two threaded drop rods minimum

M10 and a two-part industrial circular band The ends

of each band section are bent outwards Fasten the band

sections together and attach them to the drop rods with

hexagonal nuts and washers Place these hangers inside

the insulation The rods do not need to be protected by

insulation

When fixing them to a concrete construction use all-

steel expanding anchors to fasten the threaded rod

hangers to concrete soffits The anchors should penetrate

the concrete by at least 60 mm When fixing to a steel

supporting construction drill a hole through the steel

member allowing the drop rod to be supported by a steel

nut and washer above If a clamp type fixing is used the

clamp must be steel suitable for the purpose It should

pass around the steel member and be fastened back on

itself Clamps that rely on friction to hold them in place

are not suitable

Insulation

Rectangular ducts are insulated by Orstech 65 H slabs

(with apparent density 65 kgm3 and with one-sidedaluminium foil facing) with 40 mm thickness (60 mm

for fire resistance EI 60 for a horizontal duct) Circular

ducts are insulated by lamella mats Orstech LSP PYRO

with 50 mm thickness Insulation slabs (lamella mats)

need to be cut to fit the duct as tightly as possible the

insulation may need to be cut to fit around flanged duct

joints Install the insulation so that one slab (lamella

mat) is adjacent and tightly fitted against the other No

gaps must be present between butt joints of insulation

Insulation can be easily cut with a standard laggers knife

There is no need for adhesive on joints All the joints shall

be sealed by aluminium tape For rectangular ducts in theposition of flange the slabs are snick first 15 mm of the

thickness to avoid lifting of the slabs Butt joints should

be positioned out of flanges Fire protective insulation for

circular ducts does not require usage of a wire net mesh

on the outer side of insulation

Stud welded pins

The insulation is fixed to the duct using steel pins 27 mm

to 3 mm nominal diameter and spring steel washers

minimum 30 mm diameter The length of pin should

be equal to the insulation thickness The orientational

number of pins is 16 piecesm2 for rectangular ducts and14 piecesm2 for circular ducts

Recommended distance from duct edges and joints is

80 mm 50 mm from flanges

Wallfloor penetration

At wallfloor penetration one must insure the same fire

resistance of ventilation duct as has the fire separation

to avoid the spreading of fire from one compartment to

other via a duct This is possible by two basic principles

or their combinations - install a fire damper at the

penetration point or use insulation with fire resistancewhere the crucial thing is the fire-stopping The fire-

stopping is from the second insulation layer with the

width of 150 mm from both side of fire separation

The same general principle is used for both rectangular

and circular ducts regardless of orientation Place

the duct in the penetration of the construction with

approximately 10 mm gap between insulated duct and

opening Before installing the fire-stopping with the

same insulation thickness as is used for the first layer

pack the space between the duct and partition with

as many pieces of insulation as possible Ensure tight

compression in order to completely fill the opening This

must be done because system ORSTECH Protect does

not require stiffeners inside the duct Then install thesecond insulation layer so that it is adjacent and tightly

fitted against the penetration The insulation must be

cut leaving excess length so that it exerts some pressure

between the penetration and the last fitted piece of

insulation

The second layer is fixed by welded pins with length

equal to double insulation thickness The second layer for

circular ducts (lamella mats) is clamped with 1-2 wires

with a diameter 16 mm Then the insulation is secured

to the duct by welded pins

A inovative solution is the considerable simplification of

a fire-stopping concept There is no need to use any kind

of stiffener either inside or outside of the duct A great

advantage is to mount the whole ventilation section

at once and the wall itself can be placed anywhere

Therefore the position variability of fire separation is

provided No glue or mastic is needed at wallfloor

penetrations

Fire classification

ORSTECH Protect insulation with fire resistance has

been tested by the fire testing laboratory Pavus as an

authorised body AO 216 Classification protocols on the

request

Fire protection system ORSTECH Protect has been tested

in accordance with EN 1366-1 Maximum size for the

rectangular duct is 1250 x 1000 mm and for the circular

duct up to diameter 1000 mm If a duct has bigger

dimensions the certificate connected to the standard

cannot be used

to provide compensation for pipe expansion and

contraction

to reduce heat flow by staggering joints thus creatinga more thermally efficient installation

to achieve thickness in excess of manufacturersrsquo

capabilities

for retrofitting purposes

Insulation is usually fixed by mechanical fasteners - by

studs or pins Spacing between them is dependent on the

design of the vessel its surface temperature fire hazard

potential involved and presumptive loading Each slab

should be fixed by minimally two pins

BOILER INSULATIONInsulations for boilers kettles and ovens are one of

the most demanding applications in industry because

these units are operating at very high temperatures

Good insulation not only saves energy considerably but

the main purpose is personal protection against burn

According to the surface shape and temperature are used

either slabs with higher densities Orstech 65 to 110 (for

boilers with flat surfaces) or wired mats Orstech DP 65 to

DP 100 (for boilers with cylindrical parts)

Boiler walls are exposed to very high temperatures

(usually around 500 or 600 degC) Therefore it is essential

to use mechanical fasteners for the fixing of insulation

to the surface Insulation for boilers is done in at least

two layers each layer must be staggered when applied

Each layer must be secured in place before the next is

applied A product with high density should be placed as

the first layer because it has a higher maximum surface

temperature (higher resistance against high operating

temperatures) and better insulation performace than

products with lower densities

CHIMNEY INSULATION

Insulations for prefabricated chimneys are directly

supplied by producers of such systems In cooperation

with specialized wholesale companies we offer slabs

with multi-plate stripes which allow easy and perfect

application for prefabricated chimneys suitable both

for stainless steel chimney liners as well as with other

brands of chimney lining systems The main advantage

is the time saving during the installation in comparison

with the use of lamella mats and horizontal orientation

of fibres (better thermal conductivity) Insulation

dimensions ie thickness of slabs and groove dimensions

dependent on the chimney diameter are supplied

according to customer needs

For non-prefabricated chimneys are mostly used wired

mats Orstech DP or slabs Orstech 90 or 110 (for chimneys

with rectangular cross-section)

TECHNOLOGICAL APPLIANCEINSULATIONWhere big quantities of energy is used eg within

petrochemical paper and pulp industries thermal

insulation is necessary in order to reduce expensive

energy losses Tanks vessels exhausts exchangers

and technological piping are appliances that are often

working at high temperatures Good insulation will save

energy considerably which will benefit the environment

and keep the working costs down At the same time

the insulation will reduce temperature fall which could

disturb the production process

Proper insulation can be chosen in accordance with

dimension surface temperature the manner of fixing

and requirements for jacketing For pipes and cylindrical

parts are used lamella mats Orstech LSP H and Isover

ML-3 (only for temperatures up to 250 degC) or wired mats

Orstech DP For appliances and vessels with rectangular

shapes Orstech slabs are suitable (type according to a

surface temperature) Slabs can have aluminium facing

If insulation is done in more than one layer each layer

is staggered when applied Each layer must be secured

in place before the next is applied The decision to use

multiple layers may be made for one or more of the

following reasons

DUCTING INSULATION

Isover products are designed to provide high levels of

thermal acoustic and fire protection insulation in HVACductwork applications such as rectangular flat oval and

circular ductwork

The most suitable insulation materials for ducts are

felts KLIMAROL with aluminium foil facing lamella mats

Orstech LSP or Isover ML-3 wired mats Orstech DP or

slabs Orstech H with aluminium foil facing

Duct insulation mounting

Insulation is mostly fixed to the duct by welded pinsWhen using Orstech H slabs with aluminium facing all

the joints shall be sealed with aluminium tape If a steel

clamping band is used it is necessary to use thin-walled

steel L-profiles to avoid trimming of the insulation If

using Orstech slabs without aluminium facing or Orstech

DP wired mats proper jacketing shall be made (the most

suitable is metal steel jacketing)

FIRE PROTECTION OF VENTILATION DUCT

Description

It is vital to develop safe durable and reliable solutions

for ventilation systems as fire can easily spread from the

point of origin via ductwork Isover meets the highest

standards for fire protection providing excellent fire

resistance and top-rated reaction to fire performance

Rectangular ducts shall be insulated by Orstech 65 H

slabs with 40 mm thickness (60 mm for fire resistance EI

60 for a horizontal duct) circular ducts shall be insulated

by Orstech LSP PYRO lamella mats with 50 mm thickness

By these solutions fire resistances EI 15 30 45 and 60 S

have been certified to comply with EN 1366-1

Orstech system with fire resistance has been proven to

meet the requirements of all possible scenarios for fire

from the outside The scenarios can be identified by duct

orientation and duct shape (see table below) Horizontal

ducts normally serve one floor of a building Vertical

ducts normally serve between floors of a building All

scenarios have been done only with one layer Insulation

is fixed to a duct by welded pins Such solution is time

and material saving

Metal ductworkThe steel duct is constructed in sections of galvanised

steel sheet or stainless steel sheet minimum 08 mm thick

(standard duct sheeting for rectangular ducts specified

in DIN 24190 for circular ducts in DIN 24145) Maximum

duct size for which classification protocol is valid is 1250

mm (width) x 1000 mm (height) for rectangular duct or

diameter up to 1000 mm for a circular duct

At each cross joint flanges are fastened to the duct

with spot welds at 150 mm nominal centres

Use a ceramic tape gasket and fire-stopping mastic

between the flanges to seal the joints

Flanges are bolted together with an M10 steel nut

and bolt at each corner

Fasten the flanges together with steel clamps with

bolts M8 (see the figure) in quantity of 3 clamps per 1

meter of the flange length

Drop rods and hangers

Rectangular ducts are suspended by threaded rods and

channel section bearers A duct shall be hung with asuspension system which is independently fire rated

according to EN 1363-1 Certificated suspension system

MUPRO is recommended for the purpose Each steel

hanger consists of two threaded drop rods minimum

M10 and a channel section bearer 3840 mm Fasten

the bearer to the drop rods using hexagonal nuts and

washers The drop rods can be positioned either inside

the insulation material or outside If drop rods are outside

there is no need to insulate them separately The bearers

are positioned inside the insulation material

Circular ducts are suspended by MUumlPRO steel hangerswhich consist of two threaded drop rods minimum

M10 and a two-part industrial circular band The ends

of each band section are bent outwards Fasten the band

sections together and attach them to the drop rods with

hexagonal nuts and washers Place these hangers inside

the insulation The rods do not need to be protected by

insulation

When fixing them to a concrete construction use all-

steel expanding anchors to fasten the threaded rod

hangers to concrete soffits The anchors should penetrate

the concrete by at least 60 mm When fixing to a steel

supporting construction drill a hole through the steel

member allowing the drop rod to be supported by a steel

nut and washer above If a clamp type fixing is used the

clamp must be steel suitable for the purpose It should

pass around the steel member and be fastened back on

itself Clamps that rely on friction to hold them in place

are not suitable

Insulation

Rectangular ducts are insulated by Orstech 65 H slabs

(with apparent density 65 kgm3 and with one-sidedaluminium foil facing) with 40 mm thickness (60 mm

for fire resistance EI 60 for a horizontal duct) Circular

ducts are insulated by lamella mats Orstech LSP PYRO

with 50 mm thickness Insulation slabs (lamella mats)

need to be cut to fit the duct as tightly as possible the

insulation may need to be cut to fit around flanged duct

joints Install the insulation so that one slab (lamella

mat) is adjacent and tightly fitted against the other No

gaps must be present between butt joints of insulation

Insulation can be easily cut with a standard laggers knife

There is no need for adhesive on joints All the joints shall

be sealed by aluminium tape For rectangular ducts in theposition of flange the slabs are snick first 15 mm of the

thickness to avoid lifting of the slabs Butt joints should

be positioned out of flanges Fire protective insulation for

circular ducts does not require usage of a wire net mesh

on the outer side of insulation

Stud welded pins

The insulation is fixed to the duct using steel pins 27 mm

to 3 mm nominal diameter and spring steel washers

minimum 30 mm diameter The length of pin should

be equal to the insulation thickness The orientational

number of pins is 16 piecesm2 for rectangular ducts and14 piecesm2 for circular ducts

Recommended distance from duct edges and joints is

80 mm 50 mm from flanges

Wallfloor penetration

At wallfloor penetration one must insure the same fire

resistance of ventilation duct as has the fire separation

to avoid the spreading of fire from one compartment to

other via a duct This is possible by two basic principles

or their combinations - install a fire damper at the

penetration point or use insulation with fire resistancewhere the crucial thing is the fire-stopping The fire-

stopping is from the second insulation layer with the

width of 150 mm from both side of fire separation

The same general principle is used for both rectangular

and circular ducts regardless of orientation Place

the duct in the penetration of the construction with

approximately 10 mm gap between insulated duct and

opening Before installing the fire-stopping with the

same insulation thickness as is used for the first layer

pack the space between the duct and partition with

as many pieces of insulation as possible Ensure tight

compression in order to completely fill the opening This

must be done because system ORSTECH Protect does

not require stiffeners inside the duct Then install thesecond insulation layer so that it is adjacent and tightly

fitted against the penetration The insulation must be

cut leaving excess length so that it exerts some pressure

between the penetration and the last fitted piece of

insulation

The second layer is fixed by welded pins with length

equal to double insulation thickness The second layer for

circular ducts (lamella mats) is clamped with 1-2 wires

with a diameter 16 mm Then the insulation is secured

to the duct by welded pins

A inovative solution is the considerable simplification of

a fire-stopping concept There is no need to use any kind

of stiffener either inside or outside of the duct A great

advantage is to mount the whole ventilation section

at once and the wall itself can be placed anywhere

Therefore the position variability of fire separation is

provided No glue or mastic is needed at wallfloor

penetrations

Fire classification

ORSTECH Protect insulation with fire resistance has

been tested by the fire testing laboratory Pavus as an

authorised body AO 216 Classification protocols on the

request

Fire protection system ORSTECH Protect has been tested

in accordance with EN 1366-1 Maximum size for the

rectangular duct is 1250 x 1000 mm and for the circular

duct up to diameter 1000 mm If a duct has bigger

dimensions the certificate connected to the standard

cannot be used

Butt joints of insulation are placedapart from flanges

There is no need to use any

kind of stiffener either in-side or outside of the duct

to provide compensation for pipe expansion and

contraction

to reduce heat flow by staggering joints thus creatinga more thermally efficient installation

to achieve thickness in excess of manufacturersrsquo

capabilities

for retrofitting purposes

Insulation is usually fixed by mechanical fasteners - by

studs or pins Spacing between them is dependent on the

design of the vessel its surface temperature fire hazard

potential involved and presumptive loading Each slab

should be fixed by minimally two pins

BOILER INSULATIONInsulations for boilers kettles and ovens are one of

the most demanding applications in industry because

these units are operating at very high temperatures

Good insulation not only saves energy considerably but

the main purpose is personal protection against burn

According to the surface shape and temperature are used

either slabs with higher densities Orstech 65 to 110 (for

boilers with flat surfaces) or wired mats Orstech DP 65 to

DP 100 (for boilers with cylindrical parts)

Boiler walls are exposed to very high temperatures

(usually around 500 or 600 degC) Therefore it is essential

to use mechanical fasteners for the fixing of insulation

to the surface Insulation for boilers is done in at least

two layers each layer must be staggered when applied

Each layer must be secured in place before the next is

applied A product with high density should be placed as

the first layer because it has a higher maximum surface

temperature (higher resistance against high operating

temperatures) and better insulation performace than

products with lower densities

CHIMNEY INSULATION

Insulations for prefabricated chimneys are directly

supplied by producers of such systems In cooperation

with specialized wholesale companies we offer slabs

with multi-plate stripes which allow easy and perfect

application for prefabricated chimneys suitable both

for stainless steel chimney liners as well as with other

brands of chimney lining systems The main advantage

is the time saving during the installation in comparison

with the use of lamella mats and horizontal orientation

of fibres (better thermal conductivity) Insulation

dimensions ie thickness of slabs and groove dimensions

dependent on the chimney diameter are supplied

according to customer needs

For non-prefabricated chimneys are mostly used wired

mats Orstech DP or slabs Orstech 90 or 110 (for chimneys

with rectangular cross-section)

TECHNOLOGICAL APPLIANCEINSULATIONWhere big quantities of energy is used eg within

petrochemical paper and pulp industries thermal

insulation is necessary in order to reduce expensive

energy losses Tanks vessels exhausts exchangers

and technological piping are appliances that are often

working at high temperatures Good insulation will save

energy considerably which will benefit the environment

and keep the working costs down At the same time

the insulation will reduce temperature fall which could

disturb the production process

Proper insulation can be chosen in accordance with

dimension surface temperature the manner of fixing

and requirements for jacketing For pipes and cylindrical

parts are used lamella mats Orstech LSP H and Isover

ML-3 (only for temperatures up to 250 degC) or wired mats

Orstech DP For appliances and vessels with rectangular

shapes Orstech slabs are suitable (type according to a

surface temperature) Slabs can have aluminium facing

If insulation is done in more than one layer each layer

is staggered when applied Each layer must be secured

in place before the next is applied The decision to use

multiple layers may be made for one or more of the

following reasons

FIRE PROTECTION OF VENTILATION DUCT

Description

It is vital to develop safe durable and reliable solutions

for ventilation systems as fire can easily spread from the

point of origin via ductwork Isover meets the highest

standards for fire protection providing excellent fire

resistance and top-rated reaction to fire performance

Rectangular ducts shall be insulated by Orstech 65 H

slabs with 40 mm thickness (60 mm for fire resistance EI

60 for a horizontal duct) circular ducts shall be insulated

by Orstech LSP PYRO lamella mats with 50 mm thickness

By these solutions fire resistances EI 15 30 45 and 60 S

have been certified to comply with EN 1366-1

Orstech system with fire resistance has been proven to

meet the requirements of all possible scenarios for fire

from the outside The scenarios can be identified by duct

orientation and duct shape (see table below) Horizontal

ducts normally serve one floor of a building Vertical

ducts normally serve between floors of a building All

scenarios have been done only with one layer Insulation

is fixed to a duct by welded pins Such solution is time

and material saving

Metal ductworkThe steel duct is constructed in sections of galvanised

steel sheet or stainless steel sheet minimum 08 mm thick

(standard duct sheeting for rectangular ducts specified

in DIN 24190 for circular ducts in DIN 24145) Maximum

duct size for which classification protocol is valid is 1250

mm (width) x 1000 mm (height) for rectangular duct or

diameter up to 1000 mm for a circular duct

At each cross joint flanges are fastened to the duct

with spot welds at 150 mm nominal centres

Use a ceramic tape gasket and fire-stopping mastic

between the flanges to seal the joints

Flanges are bolted together with an M10 steel nut

and bolt at each corner

Fasten the flanges together with steel clamps with

bolts M8 (see the figure) in quantity of 3 clamps per 1

meter of the flange length

Drop rods and hangers

Rectangular ducts are suspended by threaded rods and

channel section bearers A duct shall be hung with asuspension system which is independently fire rated

according to EN 1363-1 Certificated suspension system

MUPRO is recommended for the purpose Each steel

hanger consists of two threaded drop rods minimum

M10 and a channel section bearer 3840 mm Fasten

the bearer to the drop rods using hexagonal nuts and

washers The drop rods can be positioned either inside

the insulation material or outside If drop rods are outside

there is no need to insulate them separately The bearers

are positioned inside the insulation material

Circular ducts are suspended by MUumlPRO steel hangerswhich consist of two threaded drop rods minimum

M10 and a two-part industrial circular band The ends

of each band section are bent outwards Fasten the band

sections together and attach them to the drop rods with

hexagonal nuts and washers Place these hangers inside

the insulation The rods do not need to be protected by

insulation

When fixing them to a concrete construction use all-

steel expanding anchors to fasten the threaded rod

hangers to concrete soffits The anchors should penetrate

the concrete by at least 60 mm When fixing to a steel

supporting construction drill a hole through the steel

member allowing the drop rod to be supported by a steel

nut and washer above If a clamp type fixing is used the

clamp must be steel suitable for the purpose It should

pass around the steel member and be fastened back on

itself Clamps that rely on friction to hold them in place

are not suitable

Insulation

Rectangular ducts are insulated by Orstech 65 H slabs

(with apparent density 65 kgm3 and with one-sidedaluminium foil facing) with 40 mm thickness (60 mm

for fire resistance EI 60 for a horizontal duct) Circular

ducts are insulated by lamella mats Orstech LSP PYRO

with 50 mm thickness Insulation slabs (lamella mats)

need to be cut to fit the duct as tightly as possible the

insulation may need to be cut to fit around flanged duct

joints Install the insulation so that one slab (lamella

mat) is adjacent and tightly fitted against the other No

gaps must be present between butt joints of insulation

Insulation can be easily cut with a standard laggers knife

There is no need for adhesive on joints All the joints shall

be sealed by aluminium tape For rectangular ducts in theposition of flange the slabs are snick first 15 mm of the

thickness to avoid lifting of the slabs Butt joints should

be positioned out of flanges Fire protective insulation for

circular ducts does not require usage of a wire net mesh

on the outer side of insulation

Stud welded pins

The insulation is fixed to the duct using steel pins 27 mm

to 3 mm nominal diameter and spring steel washers

minimum 30 mm diameter The length of pin should

be equal to the insulation thickness The orientational

number of pins is 16 piecesm2 for rectangular ducts and14 piecesm2 for circular ducts

Recommended distance from duct edges and joints is

80 mm 50 mm from flanges

Wallfloor penetration

At wallfloor penetration one must insure the same fire

resistance of ventilation duct as has the fire separation

to avoid the spreading of fire from one compartment to

other via a duct This is possible by two basic principles

or their combinations - install a fire damper at the

penetration point or use insulation with fire resistancewhere the crucial thing is the fire-stopping The fire-

stopping is from the second insulation layer with the

width of 150 mm from both side of fire separation

The same general principle is used for both rectangular

and circular ducts regardless of orientation Place

the duct in the penetration of the construction with

approximately 10 mm gap between insulated duct and

opening Before installing the fire-stopping with the

same insulation thickness as is used for the first layer

pack the space between the duct and partition with

as many pieces of insulation as possible Ensure tight

compression in order to completely fill the opening This

must be done because system ORSTECH Protect does

not require stiffeners inside the duct Then install thesecond insulation layer so that it is adjacent and tightly

fitted against the penetration The insulation must be

cut leaving excess length so that it exerts some pressure

between the penetration and the last fitted piece of

insulation

The second layer is fixed by welded pins with length

equal to double insulation thickness The second layer for

circular ducts (lamella mats) is clamped with 1-2 wires

with a diameter 16 mm Then the insulation is secured

to the duct by welded pins

A inovative solution is the considerable simplification of

a fire-stopping concept There is no need to use any kind

of stiffener either inside or outside of the duct A great

advantage is to mount the whole ventilation section

at once and the wall itself can be placed anywhere

Therefore the position variability of fire separation is

provided No glue or mastic is needed at wallfloor

penetrations

Fire classification

ORSTECH Protect insulation with fire resistance has

been tested by the fire testing laboratory Pavus as an

authorised body AO 216 Classification protocols on the

request

Fire protection system ORSTECH Protect has been tested

in accordance with EN 1366-1 Maximum size for the

rectangular duct is 1250 x 1000 mm and for the circular

duct up to diameter 1000 mm If a duct has bigger

dimensions the certificate connected to the standard

cannot be used

to provide compensation for pipe expansion and

contraction

to reduce heat flow by staggering joints thus creatinga more thermally efficient installation

to achieve thickness in excess of manufacturersrsquo

capabilities

for retrofitting purposes

Insulation is usually fixed by mechanical fasteners - by

studs or pins Spacing between them is dependent on the

design of the vessel its surface temperature fire hazard

potential involved and presumptive loading Each slab

should be fixed by minimally two pins

BOILER INSULATIONInsulations for boilers kettles and ovens are one of

the most demanding applications in industry because

these units are operating at very high temperatures

Good insulation not only saves energy considerably but

the main purpose is personal protection against burn

According to the surface shape and temperature are used

either slabs with higher densities Orstech 65 to 110 (for

boilers with flat surfaces) or wired mats Orstech DP 65 to

DP 100 (for boilers with cylindrical parts)

Boiler walls are exposed to very high temperatures

(usually around 500 or 600 degC) Therefore it is essential

to use mechanical fasteners for the fixing of insulation

to the surface Insulation for boilers is done in at least

two layers each layer must be staggered when applied

Each layer must be secured in place before the next is

applied A product with high density should be placed as

the first layer because it has a higher maximum surface

temperature (higher resistance against high operating

temperatures) and better insulation performace than

products with lower densities

CHIMNEY INSULATION

Insulations for prefabricated chimneys are directly

supplied by producers of such systems In cooperation

with specialized wholesale companies we offer slabs

with multi-plate stripes which allow easy and perfect

application for prefabricated chimneys suitable both

for stainless steel chimney liners as well as with other

brands of chimney lining systems The main advantage

is the time saving during the installation in comparison

with the use of lamella mats and horizontal orientation

of fibres (better thermal conductivity) Insulation

dimensions ie thickness of slabs and groove dimensions

dependent on the chimney diameter are supplied

according to customer needs

For non-prefabricated chimneys are mostly used wired

mats Orstech DP or slabs Orstech 90 or 110 (for chimneys

with rectangular cross-section)

TECHNOLOGICAL APPLIANCEINSULATIONWhere big quantities of energy is used eg within

petrochemical paper and pulp industries thermal

insulation is necessary in order to reduce expensive

energy losses Tanks vessels exhausts exchangers

and technological piping are appliances that are often

working at high temperatures Good insulation will save

energy considerably which will benefit the environment

and keep the working costs down At the same time

the insulation will reduce temperature fall which could

disturb the production process

Proper insulation can be chosen in accordance with

dimension surface temperature the manner of fixing

and requirements for jacketing For pipes and cylindrical

parts are used lamella mats Orstech LSP H and Isover

ML-3 (only for temperatures up to 250 degC) or wired mats

Orstech DP For appliances and vessels with rectangular

shapes Orstech slabs are suitable (type according to a

surface temperature) Slabs can have aluminium facing

If insulation is done in more than one layer each layer

is staggered when applied Each layer must be secured

in place before the next is applied The decision to use

multiple layers may be made for one or more of the

following reasons

Insulation

Rectangular ducts are insulated by Orstech 65 H slabs

(with apparent density 65 kgm3 and with one-sidedaluminium foil facing) with 40 mm thickness (60 mm

for fire resistance EI 60 for a horizontal duct) Circular

ducts are insulated by lamella mats Orstech LSP PYRO

with 50 mm thickness Insulation slabs (lamella mats)

need to be cut to fit the duct as tightly as possible the

insulation may need to be cut to fit around flanged duct

joints Install the insulation so that one slab (lamella

mat) is adjacent and tightly fitted against the other No

gaps must be present between butt joints of insulation

Insulation can be easily cut with a standard laggers knife

There is no need for adhesive on joints All the joints shall

be sealed by aluminium tape For rectangular ducts in theposition of flange the slabs are snick first 15 mm of the

thickness to avoid lifting of the slabs Butt joints should

be positioned out of flanges Fire protective insulation for

circular ducts does not require usage of a wire net mesh

on the outer side of insulation

Stud welded pins

The insulation is fixed to the duct using steel pins 27 mm

to 3 mm nominal diameter and spring steel washers

minimum 30 mm diameter The length of pin should

be equal to the insulation thickness The orientational

number of pins is 16 piecesm2 for rectangular ducts and14 piecesm2 for circular ducts

Recommended distance from duct edges and joints is

80 mm 50 mm from flanges

Wallfloor penetration

At wallfloor penetration one must insure the same fire

resistance of ventilation duct as has the fire separation

to avoid the spreading of fire from one compartment to

other via a duct This is possible by two basic principles

or their combinations - install a fire damper at the

penetration point or use insulation with fire resistancewhere the crucial thing is the fire-stopping The fire-

stopping is from the second insulation layer with the

width of 150 mm from both side of fire separation

The same general principle is used for both rectangular

and circular ducts regardless of orientation Place

the duct in the penetration of the construction with

approximately 10 mm gap between insulated duct and

opening Before installing the fire-stopping with the

same insulation thickness as is used for the first layer

pack the space between the duct and partition with

as many pieces of insulation as possible Ensure tight

compression in order to completely fill the opening This

must be done because system ORSTECH Protect does

not require stiffeners inside the duct Then install thesecond insulation layer so that it is adjacent and tightly

fitted against the penetration The insulation must be

cut leaving excess length so that it exerts some pressure

between the penetration and the last fitted piece of

insulation

The second layer is fixed by welded pins with length

equal to double insulation thickness The second layer for

circular ducts (lamella mats) is clamped with 1-2 wires

with a diameter 16 mm Then the insulation is secured

to the duct by welded pins

A inovative solution is the considerable simplification of

a fire-stopping concept There is no need to use any kind

of stiffener either inside or outside of the duct A great

advantage is to mount the whole ventilation section

at once and the wall itself can be placed anywhere

Therefore the position variability of fire separation is

provided No glue or mastic is needed at wallfloor

penetrations

Fire classification

ORSTECH Protect insulation with fire resistance has

been tested by the fire testing laboratory Pavus as an

authorised body AO 216 Classification protocols on the

request

Fire protection system ORSTECH Protect has been tested

in accordance with EN 1366-1 Maximum size for the

rectangular duct is 1250 x 1000 mm and for the circular

duct up to diameter 1000 mm If a duct has bigger

dimensions the certificate connected to the standard

cannot be used

More information

For more information about fire protective systems

sheets

Butt joints of insulation are placedapart from flanges

There is no need to use any

kind of stiffener either in-side or outside of the duct

to provide compensation for pipe expansion and

contraction

to reduce heat flow by staggering joints thus creatinga more thermally efficient installation

to achieve thickness in excess of manufacturersrsquo

capabilities

for retrofitting purposes

Insulation is usually fixed by mechanical fasteners - by

studs or pins Spacing between them is dependent on the

design of the vessel its surface temperature fire hazard

potential involved and presumptive loading Each slab

should be fixed by minimally two pins

BOILER INSULATIONInsulations for boilers kettles and ovens are one of

the most demanding applications in industry because

these units are operating at very high temperatures

Good insulation not only saves energy considerably but

the main purpose is personal protection against burn

According to the surface shape and temperature are used

either slabs with higher densities Orstech 65 to 110 (for

boilers with flat surfaces) or wired mats Orstech DP 65 to

DP 100 (for boilers with cylindrical parts)

Boiler walls are exposed to very high temperatures

(usually around 500 or 600 degC) Therefore it is essential

to use mechanical fasteners for the fixing of insulation

to the surface Insulation for boilers is done in at least

two layers each layer must be staggered when applied

Each layer must be secured in place before the next is

applied A product with high density should be placed as

the first layer because it has a higher maximum surface

temperature (higher resistance against high operating

temperatures) and better insulation performace than

products with lower densities

CHIMNEY INSULATION

Insulations for prefabricated chimneys are directly

supplied by producers of such systems In cooperation

with specialized wholesale companies we offer slabs

with multi-plate stripes which allow easy and perfect

application for prefabricated chimneys suitable both

for stainless steel chimney liners as well as with other

brands of chimney lining systems The main advantage

is the time saving during the installation in comparison

with the use of lamella mats and horizontal orientation

of fibres (better thermal conductivity) Insulation

dimensions ie thickness of slabs and groove dimensions

dependent on the chimney diameter are supplied

according to customer needs

For non-prefabricated chimneys are mostly used wired

mats Orstech DP or slabs Orstech 90 or 110 (for chimneys

with rectangular cross-section)

TECHNOLOGICAL APPLIANCEINSULATIONWhere big quantities of energy is used eg within

petrochemical paper and pulp industries thermal

insulation is necessary in order to reduce expensive

energy losses Tanks vessels exhausts exchangers

and technological piping are appliances that are often

working at high temperatures Good insulation will save

energy considerably which will benefit the environment

and keep the working costs down At the same time

the insulation will reduce temperature fall which could

disturb the production process

Proper insulation can be chosen in accordance with

dimension surface temperature the manner of fixing

and requirements for jacketing For pipes and cylindrical

parts are used lamella mats Orstech LSP H and Isover

ML-3 (only for temperatures up to 250 degC) or wired mats

Orstech DP For appliances and vessels with rectangular

shapes Orstech slabs are suitable (type according to a

surface temperature) Slabs can have aluminium facing

If insulation is done in more than one layer each layer

is staggered when applied Each layer must be secured

in place before the next is applied The decision to use

multiple layers may be made for one or more of the

following reasons

to provide compensation for pipe expansion and

contraction

to reduce heat flow by staggering joints thus creatinga more thermally efficient installation

to achieve thickness in excess of manufacturersrsquo

capabilities

for retrofitting purposes

Insulation is usually fixed by mechanical fasteners - by

studs or pins Spacing between them is dependent on the

design of the vessel its surface temperature fire hazard

potential involved and presumptive loading Each slab

should be fixed by minimally two pins

BOILER INSULATIONInsulations for boilers kettles and ovens are one of

the most demanding applications in industry because

these units are operating at very high temperatures

Good insulation not only saves energy considerably but

the main purpose is personal protection against burn

According to the surface shape and temperature are used

either slabs with higher densities Orstech 65 to 110 (for

boilers with flat surfaces) or wired mats Orstech DP 65 to

DP 100 (for boilers with cylindrical parts)

Boiler walls are exposed to very high temperatures

(usually around 500 or 600 degC) Therefore it is essential

to use mechanical fasteners for the fixing of insulation

to the surface Insulation for boilers is done in at least

two layers each layer must be staggered when applied

Each layer must be secured in place before the next is

applied A product with high density should be placed as

the first layer because it has a higher maximum surface

temperature (higher resistance against high operating

temperatures) and better insulation performace than

products with lower densities

CHIMNEY INSULATION

Insulations for prefabricated chimneys are directly

supplied by producers of such systems In cooperation

with specialized wholesale companies we offer slabs

with multi-plate stripes which allow easy and perfect

application for prefabricated chimneys suitable both

for stainless steel chimney liners as well as with other

brands of chimney lining systems The main advantage

is the time saving during the installation in comparison

with the use of lamella mats and horizontal orientation

of fibres (better thermal conductivity) Insulation

dimensions ie thickness of slabs and groove dimensions

dependent on the chimney diameter are supplied

according to customer needs

For non-prefabricated chimneys are mostly used wired

mats Orstech DP or slabs Orstech 90 or 110 (for chimneys

with rectangular cross-section)

TECHNOLOGICAL APPLIANCEINSULATIONWhere big quantities of energy is used eg within

petrochemical paper and pulp industries thermal

insulation is necessary in order to reduce expensive

energy losses Tanks vessels exhausts exchangers

and technological piping are appliances that are often

working at high temperatures Good insulation will save

energy considerably which will benefit the environment

and keep the working costs down At the same time

the insulation will reduce temperature fall which could

disturb the production process

Proper insulation can be chosen in accordance with

dimension surface temperature the manner of fixing

and requirements for jacketing For pipes and cylindrical

parts are used lamella mats Orstech LSP H and Isover

ML-3 (only for temperatures up to 250 degC) or wired mats

Orstech DP For appliances and vessels with rectangular

shapes Orstech slabs are suitable (type according to a

surface temperature) Slabs can have aluminium facing

If insulation is done in more than one layer each layer

is staggered when applied Each layer must be secured

in place before the next is applied The decision to use

multiple layers may be made for one or more of the

following reasons
