HVAC & Pipework Insulation Product Selector PAGE 3

Designing and selecting the right materials to meet Building

Code and end user requirements is critical during the design

phase of a project. With the introduction of amendments

to the National Construction Code of Australia for 2014,

CSR Bradford has updated this HVAC & Pipework manual

to incorporate the latest changes to the Energy Efficiency

provisions for Class 2-9 commercial buildings contained

within the Building Code of Australia (BCA).

This manual provides guidance on:

The Building Code energy efficiency provisions for

flexible and rigid HVAC ducting & Pipework insulation;

How to meet and exceed these BCA requirements with

CSR Bradford insulation products;

Functional and decorative insulation blanket facing

options to suit a broad range of applications.

In addition to this manual, the CSR Bradford online

DesignSmart suite of resources provides access to a

broad range of useful resources, check online at

www.bradfordinsulation.com.au/designsmart

The Building Code represents the minimum level of

insulation for good energy efficiency and performance of

the building envelope. Given the relatively low capital cost

of insulation, increasing roofing insulation R-Values during

the design phase can decrease the air conditioning load,

thus reducing project capital equipment costs as well as

future running costs.

Important Note: In some climates and air conditioning

applications, the minimum ductwork insulation requirements

specified in the BCA for energy efficiency may be insufficient

for either optimum energy efficiency performance of the

system or for control of condensation. CSR Bradford

recommends that a qualified Mechanical Services Engineer

always be consulted when specifying duct insulation for

your project.

HVAC & Pipework Insulation Product Selector

2.1 The benefits of insulation

Helps meet or exceed the BCA Energy Efficiency

requirements by providing thermal insulation - by meeting

these requirements your smart design helps reduce

greenhouse gas emissions;

Provide a more comfortable working environment for

occupants by reducing heat transfer in the HVAC system

and delivering more consistent air temperature;

A better working environment, by reducing air movement

and fan noise transmission through the ductwork;

A safer environment, as it reduces the possibility of fire

spread through the duct in the event of a fire in the HVAC

duct space;

Minimises the risk of damage to internal ceiling linings

caused by condensation;

Decreases building running costs, by reducing the load

required to heat and cool the space and/or the size of the

heating/cooling plant.

2.2 Designing for BCA Section J and Green Star

The Building Code of Australia (BCA) provides the minimum

Deemed-to-Satisfy total thermal performance required

for roofs. Insulation plays a major role in achieving these

minimum values.

In Green Star buildings one of the highest factors that

contribute to the achievement of Green Star points is energy

improvement. The upgrade of passive insulation within a

building can result in significant energy savings.

Regardless of the building achieving a Green Star rating or

meeting Deemed-to-Satisfy provisions of the BCA, there is

a strong case to increase specified insulation performance

as the energy savings can quickly pay for the increase in

capital costs.

2.3 Designing to control condensation

Condensation can become a problem when warm, moist

air comes in contact with a colder surface. Under these

conditions, condensation can form and can cause damage to

the HVAC duct as well as the surrounding building structure.

Condensation management is a critical component that

needs to be considered during the design phase and

care should be taken to select only vapour impermeable

facing materials if there is a risk of condensation. Please

ensure that your Mechanical Services Engineer reviews all

recommendations prior to installation.

2.4 Designing for noise control

HVAC ducts are primarily insulated internally for noise

absorption, as internal insulation is usually more cost

effective than using additional silencers or attenuators to

control noise. CSR Bradford offers a broad range of internal

ductlining insulation products and facings to optimise the

sound absorption performance of the duct whilst providing

thermal performance to meet BCA Energy Efficiency targets.

Technical information relating to the Noise Reduction

Co-efficient (NRC) of CSR Bradford insulation products is

contained in Table [5.1].

2.5 Designing for indoor air quality

CSR Bradford is the only approved insulation partner of the

National Asthma Council Australia Sensitive Choice program.

This program recognises companies who develop products

like Supertel, that may be better choices for people with

asthma or allergies.

Another aspect of indoor air quality is the ability to clean the

inside of the duct. CSR Bradford’s Enviroduct range includes

the Acoustituff facing which allows for easy cleaning, even

with a mechanical duct cleaner.

2.6 Designing to control fire risk

The fuel load of a building is a major consideration for Fire

Engineers. The CSR Bradford HVAC insulation range is made

using inert mineral fibres as the insulator base fibre, making

it a safer alternative than a hydrocarbon base material

(eg. polyester). As mineral fibres are inorganic and are

deemed non-combustible, the base insulator material has

a low average effective heat of combustion making it an

ideal material for use as a HVAC duct liner.

A range of facing products that can meet the BCA Fire

Hazard Properties are also available - please ensure that

your Fire Engineer and/or insurance assessor reviews all

recommendations prior to installation.

2.7 Designing for installed cost

CSR Bradford insulation products are quick to install. One

of the attributes of FBS-1 safe-to-handle Glasswool is that it

can be easily cut and fixed on standard fixing pins. Alternative

products, such as polyester are more difficult to cut and fix

which may result in delays to other trades following insulation

contractors.


2.8 Designing for sustainability

CSR Bradford glasswool insulation is manufactured from up

to 65% recycled glass which is not suitable for recycling in

other processes and would otherwise go to landfill.

CSR Bradford has undertaken an audit of our Glasswool and

Reflective Foil Laminate insulation manufacturing processes

referencing the US EPA List of Ozone Depleting Substances

(Class 1 and Class 2). The audit found that no ozone

depleting substances are involved in either the manufacture

or composition of these products. Our conclusion is that

CSR Bradford’s Glasswool and Reflective Foil Laminates

have an Ozone Depleting Potential of zero.

CSR Bradford recognises that, as an insulation supplier we

have a significant role to play in the passive reduction of

energy use in our world. Please refer to the CSR Bradford

MSDS for supporting information.

2.9 Understanding R-Values & the BCA requirement

As most CSR Bradford HVAC insulation products combine

a Glasswool base blanket with a facing, a very wide range

of products is available. In order to select the right product

combination for your application, CSR Bradford recommend

that you determine the blanket thickness required to meet

the thermal requirements of the project and then select

the facing that provides the best level of performance or

aesthetics for your particular application.

AS/NZS4859.1:2002 allows insulation manufacturers to

present the performance of insulation either as a material

value (RM) or a total system value (R

T). In order to ensure

proper product representation and accurate performance

and cost comparison of products, it is important that the

distinction between the two classifications is clear.

MATERIAL R-VALUE (RM)

This is the raw performance of the base insulation material

excluding the insulation contribution of any materials used in the

construction of the building.

Note: RM is directly proportional to the insulation material thickness

TOTAL SYSTEM R-VALUE (RT)

This is the overall performance of the roofing system, including

the base insulation material, contribution of materials used in

the construction of the building, air spaces, air film resistances

and emissivity of the insulation facing material.

Section J5.2 of the BCA requires that all HVAC materials

achieve a minimum material R-Value (RM). When comparing

insulation materials, always ensure that you compare only the

material R-Value (RM) as the total system R-Value (R

T) is not

applicable to HVAC insulating products.

2.10 Designing for aesthetics

In applications where the ductwork is exposed or the lighting

is such that the internal lining of the ductwork is visible, CSR

Bradford is able to offer a range of black facing materials

that will minimise the appearance of the insulation material.

Further information is available in the Facing section of this

manual.

Non-perforated Acoustituff™ facing is suitable for ducts that need

to control condensation and also need to be cleaned.

Black Ultraphon™ facing is suitable for applications where the

duct maybe partially visible or where acoustics are important,

but not for the control of condensation.


The BCA makes provisions for energy efficiency in conditioned

spaces, sound insulation and fire protection for public

buildings. These recognise that well insulated buildings that

control heat and cold, along with good acoustic insulation are

important elements of good building design.

Please note that the following information is a guide only and

CSR Bradford recommends that you work closely with your

building surveyor/private certifier, fire engineering consultant

and insurance provider early in the design phase of your

building to ensure compliance where appropriate to your

specific building type and project requirements.

To provide long term energy savings with a minimal increase

in initial installation cost, CSR Bradford recommends an

incremental increase in insulation performance above

the BCA Section J Deemed-to-Satisfy minimum insulation

levels. Increasing insulation levels will quickly pay dividends

for building owners, representing a short term return on

installation costs as the benefits of reduced energy costs

can be passed on to building occupants and ultimately

contribute to a reduction of greenhouse gases.

Please note that compliance can be achieved via verification

with an acceptable rating scheme or using the Deemed-to-

Satisfy provisions in the BCA.

The CSR Bradford DesignSmart program has been developed

specifically to help simplify the process of meeting the

Deemed-to-Satisfy provisions of the BCA, follow these simple

steps to specify the HVAC or Pipework insulation for your

project.

A. Select the climate zone for your project location from the BCA map

B. Determine the required compliant thermal performance

C. For your HVAC duct or pipework system, select the minimum required insulation product

4.1 Introduction

Choosing the right product for your project is essential to

ensure the proper performance and appearance. This section

provides basic guidance on insulation and facing product

selection, but if you are in doubt please contact CSR Bradford

for expert advice specific to your project needs.

4.2 Ductwork product application guide

Ducts are primarily insulated internally for noise absorption.

Internal insulation is usually more cost effective than using

additional silencers or attenuators to control noise.

Internal insulation also assists with compliance with the

BCA thermal energy efficiency provisions. If there is no

internal insulation then the duct must be externally lagged to

achieve the required thermal performance.

There are many CSR Bradford base blanket and facing

permutations that can be manufactured. However, the most

applicable and cost effective solutions are shown below in

Table [4.1]

4.3 Available facings for HVAC applications

The listed insulation products are available in a range of facings as shown below. Please note that only facings that are

vapour impermeable are suitable for condensation control.
