Sound Attenuated Drainage

In response to PPG3 and high density

living, the UK construction industry is,

more than ever, seeking new ways to

control noise in residential buildings.

Reducing noise in pipework is an

essential consideration. Recent changes

to Part E of the building regulations mean

that acoustic standards in buildings are

higher than ever, and as a leading pipe

manufacturer, Wavin Plastics recommend

using Osma SiTech for soil stacks to

achieve the best possible result.

Features and Benefits

High Density Material

A minerally reinforced polypropylene.

Because of its high specific weight and

its special molecular structure,

Astolan® is able to absorb airborne

sound as well as structure borne

sound.

Easy Installation - quick and

economic in comparison to cast iron

Osma SiTech is lightweight thus easy to

handle. Installation is quick and easy,

due to the proven push fit socket

connections and easy pipe cutting,

leading to time and cost savings.

Easy Fixing

OSMA SiTech can be fixed with any

commercial pipe bracket (with rubber

insert). Expensive fixing techniques are

not necessary.

Durable

OSMA SiTech is extremely robust,

resistant to corrosion, internally very

smooth and resistant to internal

deposition.

OSMA SiTech

OSMA SiTech is an effective low noise

system, available in 110mm.

Complemented by a full range of push-fit

fittings, the system offers flexibility of an

extensive choice, excellent quality and

reliability. Compared to Cast Iron, OSMA

SiTech is quick and easy to install,

because of its socket connections.

OSMA SiTech is resistant to hot water and

fulfils the mechanical test requirements of

BSEN 1451, which means 95ºC short

term and 90ºC long term temperature

loading. Where PVC-U fittings are used,

long-term temperature resistance is

reduced and only suitable for use with

intermittent discharges of water up to

90˚C. OSMA SiTech can be used for the

drainage of wastewater between pH 2

and pH 12.

To allow waste connections to the main

stack, OSMA Sitech can be used in

conjunction with standard OSMA Soil

PVC-U push-fit branches.

The system is designed for professional

soil installations in buildings. Moreover it

can be used for roof-drainage. Compared

to Cast Iron, the OSMA SiTech soil system

provides the specifier, the plumber and

end-user with many advantages:

Acoustic Performance

Following UK site trials and acoustic

testing, LABC are satisfied that where

robust construction details are not to be

followed, use of the Wavin SiTech system

(without a mineral wool wrap) and only a

nominal plasterboard encasement should

not compromise any acoustic testing of a

penetrated floor.

DIN 4109

Wavin SiTech has been tested at the

Frauenhofer Institute for Building Physics,

Stuttgart.

Wavin SiTech performs to a high level of

sound insulation and conforms with the

acoustic requirements for pipework laid

down in DIN 4109, achieving a sound

performance of under 30dB (A) at 2l/s.

Noise Insulating Principles & Properties

General Principles

With it’s excellent noise insulating

characteristics, OSMA SiTech is the

optimal solution where noise insulation is

required. The patented raw material

Astolan® has a high specific weight and

special molecular structure, which enables

absorption of airborne sound as well as

structure borne sound.

Structure borne sound transmits from the

shock or impact zone over the whole pipe.

Due to vibration of the pipe additional

airborne sounds are generated. The

special molecular structure of OSMA

SiTech enables the absorption of structure

borne sound.

Airborne Sound

Sound which diffuses in the air. Occurs

inside the pipe due to impact and flow

noises. Sound energy is absorbed in the

pipe wall. OSMA SiTech pipe material

provides excellent airborne sound

absorbing behaviour, because of its high

specific weight and special molecular

structure.

Impact sound

Sound which diffuses in solid materials.

Structure borne sound is created by the

impact of wastewater on the pipe wall,

especially in vertical stacks in the area of

bends and branches.

Weight per metre of OSMASiTech

The weight per meter of a soil and waste

system is of great importance in absorbing

airborne and impact sounds. The

combination of high specific weight and

low elasticity gives the optimal results in

damping the transmission of both sounds

through a pipe system. OSMA SiTech is

specifically developed to make optimal

use of both properties and resulted in

relative thick walls and high specific

material weight. Therefore the pipe weight

of 110mm Osma SiTech is no less than

3.55kg/m.

General Principles

This product and installation guide is valid

for soil and waste installations in buildings

and dwellings which are constructed in

OSMA SiTech pipe and fittings.

Sound Insulation

Sound Insulation

Building regulations should be observed

where applicable.

In order to achieve optimal sound

insulation it is highly recommended to

implement the following instructions. The

OSMA SiTech pipe system must be free

from the plaster layer, avoiding sound

bridges. It is recommended to wrap a

layer of mineral wool or 5mm PE foam

around the pipe, where contact with the

structure of the building (eg plaster layer or

floor penetration) cannot be avoided.

Emitted sounds depend highly on the

course of the pipe.

The prevention or reduction of impact

zones leads to less sound emission. It is

therefore recommended to prevent abrupt

directional changes.

For optimal sound insulation, use full

encircling brackets with rubber inserts.

OSMA SiTech brackets are fitted with

rubber inserts which insulates the system

for structure borne sound.

Multiple storey buildings requiring

noise insulation:

❚ Hotels

❚ Hospitals

❚ Shopping Malls

❚ Office Buildings

❚ Residential homes

❚ Apartments

❚ Schools and Universities

OSMA SiTech pipes and fittings can be

installed in the following fields of

application:

❚ Soil Stacks

❚ Suspended Pipe Systems

❚ Internal Rainwater Systems

DESIGN PROCEDURESApplications ■ Sound Installation


DESIGN PROCEDURESInstallation

Installation

Wall Installation

In case OSMA SiTech is to be installed

against a wall with separate decorative top

layer (e.g. plaster boards), it is required

that the brackets are fixed to the

construction wall and not to the decorative

layer. Pipe penetrations through the

decorative layer can be mended by using

elastic filler.

Pipe and shaft dimensions to be taken

from the table below and figure 5.

RainWater Down Pipes

Roof drainage pipes projected through

living, sleeping and working rooms can be

installed as pictured in figure 6. The

specific area weight of the casing should

be at least equal to the wall and preferably

for both at least 220 kg/m2.

Although the formation of condensation

on the outside of OSMA SiTech pipes is

less than on metallic pipes, it is

recommended to insulate the pipes and

fittings.

Pipe Cutting and Jointing

Pipe Cutting

OSMA SiTech can be cut simply with a

commercial pipe cutter or handsaw.

Always cut the pipe straight.

When inserting pipe into the collar end

of compensator socket: (see page 19)

Remove all swarf and burrs from the cut

end and clean the pipe end. Bevel sharp

cutting edge – do not chamfer!

Inserting pipe into standard ringseal

socket

For connections to socketed pipe and

other standard ringseal sockets, the ends

of the OSMA SiTech pipe must be

chamfered.

How to Chamfer Pipe

Where chamfering is required for ringseal

sockets only (not collar/gasket end of

compensator socket) use the special

OSMA chamfering tool. Instructions are as

follows:

1. Ensure pipe is held securely.

2. Remove end cap and load sponge with

suitable lubricant.

3. Remove template from tool, snap onto

pipe and slide to required length. Mark

pipe and remove template.

4. Saw pipe to required length.

5. Ensure chamfering tool fits snugly into

the pipe.

6. With torsion control dial on first setting

(i.e one dot) turn handle in clockwise

direction applying as little downward

pressure as possible. Gradually

increase torsion control until correct

chamfer is achieved.

7. Remove tool from pipe.

8. Using lubricating sponge apply

lubrication to end of pipe.

Installation

FittingTechnique/Instructions

When making the connection with the

compensator socket the following

instruction rules should be adhered to:

❚ When installed vertically, please

ensure that the collar/gasket end is

facing down.

❚ Clean un-chamfered pipe end.

❚ Check the position and condition of the

elastomeric sealing ring in the groove.

❚ Further check the condition of the

elastomeric expansion collar.

❚ If necessary, clean fitting, sealing ring

and collar.

4. Check final position of compensator

collar. Ensure pipe end is flush with

gasket tip

3. Apply and distribute Wavin lubricant

evenly on outside of elastomeric

compensator collar. Push fitting over

compensator collar to full insertion

depth.

1. Push the expansion collar over the

pipe end. Please Note: The

expansion collar may only be pushed

over the plain pipe ends, never over

the spigot end of fittings.

2. Apply OSMA lubricant inside

compensator socket of fitting.

Never use oil or grease

5. Apply Wavin lubricant on the spigot

fitting and insert in the socket end to

full depth.

Compensator Socket

The OSMA SiTech compensator socket is

a special fitting used to connect plain

ended pipe to a branch so that:

❚ Maximum acoustic performance is

achieved by preventing structure borne

sound.

❚ Compensation is allowed for thermal

movement on every floor without the

need to employ the common practice

of withdrawing pipe by 10mm from the

fitting.

This not only saves working time, but also

gives additional technical security to the

system.

Installation

OSMA SiTech SocketConnection

For non-acoustic installations, the

compensator socket is not essential, but

an allowance for expansion using a

standard socket is still required.

The standard socket connection is to be

installed as follows:

❚ Check the position and condition of

the elastomeric sealing ring in the

groove. If necessary, clean fitting and

sealing ring.

❚ Clean and chamfer pipe end or spigot

fitting.

❚ Apply OSMA lubricant in a thin and

equal layer on pipe end.

❚ Insert pipe end straight to the central

register of the socket.

❚ Withdraw pipe by 10mm, never the

fitting

In the case of vertical soil stacks, the

individual pipe lengths must be fixed

immediately after assembly with pipe

brackets, in order to avoid the pipe from

sliding downwards and eliminating the

10mm expansion / contraction allowance.

(see Bracket Fixing Instructions)

Connection to Pre-installedPipe

This can easily be achieved using

standard OSMA SiTech fittings.

Installation instructions using double

socketed sleeves:

1. Cut out a sufficient length of pipe

(length of fitting plus 2,5x OD of pipe)

2. Cut required pass length

3. Deburr and bevel cutting edges

4. Slide branch or access pipe on upper

pipe end

5. Fit one double socketed sleeve, over

its full length, on pass length

6. Fit one double socketed sleeve, over

its full length, on lower pipe end

7. Fit in pass length and close the pipe

by sliding the double socketed

sleeves in position

8. Fix double socketed sleeves as

pictured in fig.10

Fixed Bracket FixingInstructions

The fixed bracket creates a fixed point in

the pipe system. With fixed brackets the

pipe or fitting cannot be moved through

the bracket after the screws are tightened

(no longitudinal movement is possible).

In order to prevent sliding down of the

vertical stack, each pipe section between

floors must be secured by a fixed

bracket.

Also every horizontally installed pipe

should always be fixed with one fixed

bracket. All remaining pipe brackets – in

the vertical as well as in the horizontal

installation – must be sliding brackets. The

prescribed bracket distances should not

be exceeded.

Use sound absorbing brackets,

dimensionally compatible to the pipe

diameter. Recommended are screw-pipe

brackets with rubber inserts, which are

fixed to the wall by screws and plastic

plugs.

Sliding Bracket FixingInstructions

By using sliding brackets the pipe can still

be moved through the bracket after the

screws are tightened (longitudinal

movement is possible once installed)

Installation

Bracket Arrangement

During installation of OSMA SiTech pipes,

the following should be considered:

❚ In case of horizontal installation, the

pipe bracket distances 10x the outside

diameter of the pipe. In case of

vertical pipe installation, depending on

outside diameter, 1-2 metre.

❚ Generally pipe brackets should not be

installed in impact areas. (eg diameter

reductions and changes of directions

in the system).

❚ Pipe brackets to be fixed to building

materials with high specific area weight.

❚ For stack pipes in open mounting

shafts and high rooms (storey height

over 2.5 metres) it is advised to use

one fixed bracket and one sliding

bracket per pipe length.

❚ In buildings under 3 storeys (see fig.11),

the fixed bracket must be installed

directly above the fitting at the bottom

of the pipe end. The sliding bracket

must be installed at a distance of

maximum of 2 metres above the fixed

bracket. This pattern should be

repeated on the following floors.

❚ In multiple storey buildings (from 3

storeys and more) the stack pipes of

110mm must be secured by additional

fixing (stack pipe support) to prevent

sliding. In this case we advise using the

OSMA SiTech socketed short length

with a fixed bracket (see fig.12).

Fire Protection

Method of Installation

The SiTech fire stop seals are suitable to

be installed through steel-framed

partitions, masonry walls and concrete

floors.

The minimum permissible thickness of the

masonry wall is 120mm and the minimum

permissible thickness of the concrete floor

is 150mm.

Gaps around the pipes within the

thickness of the wall or floor are sealed

with a suitable fire rated intumescent

mastic, backed by a plug of stone mineral

wool or PE foam. The mastic should be

about the same depth as the gap width.

Use the Intumescent mastic as shown

around the fire collar to prevent structure

borne sound.

SiTech Fire Collar System Performance Standards

The OSMA SiTech fire collar is suitable to

fit around minerally reinforced

polypropylene pipes with a nominal

outside diameter of 110mm (when

passing through steel framed partitions or

masonry walls with a thickness of

minimum 120mm and concrete floors with

a thickness of at least 150mm) when

tested to BSEN 1366-3:2004 for a fire

resistance period of up to 120 minutes.

The fire collar has been approved by

(LABC) Local Authority Building Control.

Description

The OSMA SiTech Intumescent fire collar

is designed to maintain the fire resistance

of compartment walls and floors where

they are penetrated by SiTech pipes. The

depth of each seal is 60mm. The seals

have a 1mm thick circular steel housing,

powder coated, with fixing lugs at the

base, spaced equidistant around the

external periphery of the collar.

Each collar is fastened be means of a

toggle clasp and has integral lugs at one

end for ease of installation.

The intumescent layers are held in position

within the steel housing using tabs at the

top of the collar, which are bent over. The

depth of the tabs are proportional to the

thickness of intumescent used. The total

intumescent used is 8mm thick. The steel

housing is produced from a single sheet of

steel.

The SiTech fire collar is suitable for use on

UPVC, MDPE, HDPE, ABS, PP and

minerally reinforced PP 110mm plastic

pipes.

Fire Protection Installation cntd

The fixings used to secure the collars to

the face of the wall, partition or floor must

be non combustible and suitable for the

material they are being secured to. Deep

threaded screws are suitable to secure the

collars to the linings of partitions. The

screws for fixing to partitions should be at

least 12mm longer than the total thickness

of the partition lining on each side of the

partition.

A SiTech fire collar must be fitted on the

fire risk side of the partition, wall or floor.

Normally, this can be assumed to be both

sides of a wall or partition, but only to the

underside of a concrete floor.

The SiTech fire collar can also be semi or

fully cast into the soffit or into a masonry

wall using astroflame fire rated mortar.

Handling and Storage

Packing

OSMA SiTech pipes and fittings are

packed ready for transport in a customer

friendly way. The packing guarantees

optimal security, efficient storage and easy

handling.

Pipes can be delivered by the bundle. 3m

length pipe is supplied in bundles of 29

pieces. 2m lengths are supplied in bundles

of 40. Bundles can be split.

The bundles can be handled with a forklift

truck.

Transport

OSMA SiTech pipes – when no longer

packed in original bundles – must lie fully

supported over their total length during

transport. Bending of the pipes should be

avoided. Impact stress on pipes and

fittings must be prevented.

Storage

If stored correctly no lasting deformations

or damage to pipes and fittings will occur.

Factory packed bundles can be stacked.

The stack of loose pipes should never be

higher than 1.5 metre.

The elastomeric sealing rings should

preferably not be stored in the open air.

This means only PE pipe should be stored

outside.
