1. InTrOdUCTIOn
Designing and selecting the right materials to meet
the building code and end user requirements is
critical during the design phase of a project. With the
introduction of the Building Code of Australia 2011
(Contained within the National Construction Code of
Australia NCC 2011), Bradford Insulation has updated
this Under Slab Product Selector to incorporate the
latest changes to the Energy Efficiency provisions for
Class 2-9 commercial buildings.
This brochure provides information on:
• The building code energy provisions for under slab
roof and floor insulation applications
• How to meet and exceed these BCA/NCC
requirements with Bradford Insulation products
• Decorative and foil facing options for a broad range
of applications
In addition to this guide, the online DesignSmart
calculator from Bradford Insulation has also been
updated to provide a real-time BCA/NCC compliant
calculator. Check online at
www.bradfordinsulation.com.au.
The BCA/NCC 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 under slab insulation
R-Values during the design phase can decrease the
heating & cooling load, thus reducing project capital
equipment costs as well as future running costs.

2. Under SlAB deSIGn COnSIderATIOnS
2.1. The Benefits of Using Insulation
• Helps meet BCA/NCC Energy Efficiency requirements,
by providing thermal insulation. By meeting these
requirements your smart design helps reduce
greenhouse gas emissions
• A more comfortable working environment, by reducing
heat flow in and out of the building
• A better working environment, by reducing external
noise and by deadening internal noise
• A safer environment, as it reduces the possibility of fire
spread in the event of a sub floor or ceiling space fire
• Reduced 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/nCC Section J
and Green Star
The Building Code of Australia (BCA) & National
Construction Code (NCC) provide the minimum total
thermal performance required for roofs and floors.
Insulation plays a major role in achieving these
minimum values.
In Green Star buildings one of the highest factors that
contribute to 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/NCC 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 for noise Control
Noise control particularly for interfloor concrete slabs
can be critical. Bradford Insulation’s range of under slab
products have been acoustically appraised and their
Noise Reduction Coefficients (NRC) are available in the
Technical Information section of this brochure.
2.4. designing to Control Fire risk
Bradford Insulation offers a range of facing
and bulk insulation products that can meet the
BCA/NCC Fire Hazard Properties and your project
needs. Please ensure that your fire engineer reviews all
recommendations prior to installation.
2.5. designing for Sustainability
Bradford Insulation glasswool is manufactured from up
to 65%, recycled content. Much of this recycled glass
is not suitable for recycling in flat or container glass
manufacture. All water used in the manufacture of our
glasswool products is also recycled.
Bradford Insulation has undertaken an audit of our
Glasswool, Rockwool and reflective foil laminate
insulation manufacturing processes referencing the
US EPA List of Ozone Depleting Substances (Class 1
and Class 2). This audit found that no ozone depleting
substances are involved in either the manufacture or
composition of these products.
Our conclusion is that Bradford Insulation’s glasswool,
rockwool and reflective foil laminates have an Ozone
Depleting Potential of zero. Bradford insulation
recognises that our products have a significant role to
play in the passive reduction of energy use in our world.

2.6. designing for Installed Cost
Bradford Insulation glasswool is quick to install. One
of the attributes of glasswool is that it can be easily
cut and drilled to enable fixings and penetrations to be
assembled through the insulation. Alternative products,
such as polyester may get caught in drill bits resulting in
delays to other trades following insulation contractors.
Drilling through Glasswool Drilling through polyester
2.7. designing for Aesthetics
Bradford Insulation offers a range of products for under
slab insulation:
• Where aesthetics are a prime consideration, higher
density products like Bradford Supertel and Ultratel
provide a smoother flatter finish.
• The Bradford Glasswool Building Blanket provides a
good finish with some pillowing.
Supertel for a high quality
aesthetic finish

2.8. designing for Indoor Air Quality
Bradford Insulation’s glasswool and rockwool insulation
have been tested and found to have low Volatile Organic
Content (VOC).
2.9. design for light requirements
A range of facing finishes are available for Bradford
under slab insulation as the colour and reflectivity of the
facing can play a critical part in ensuring that the under
slab insulation meets the lighting design requirement.

3. enerGY eFFICIenCY (SeCTIOn J)
The BCA/NCC Section J 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 is a
guide only and Bradford Insulation 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.
Bradford Insulation recommends an increase in
insulation performance over and above BCA/NCC
minimum levels. This will result in long term energy
savings for the building with little increase in overall
installed cost. Increasing insulation levels will quickly
pay dividends for building owners presenting a short
term return on installation costs. The benefits of
reduced energy costs can be passed on to building
occupants and contribute to a reduction of
greenhouse gases.
STeP A. Select the Climate Zone
Compliance can be achieved via verification with an
acceptable rating scheme or using the Deemed to
Satisfy provisions in the BCA. In part, these general
requirements are listed overleaf.
The Bradford DesignSmart program has been developed
specifically to help simplify the process of meeting the
Deemed to Satisfy provisions of Section J1 for building
elements forming the envelope of a conditioned space.
Please refer to the BCA/NCC for the complete application
of Section J and follow these simple steps to specify the
right roofing and floor underslab insulation for your project.
Select the climate zone for your project location
A. from the BCA/nCC map
B. determine the required thermal performance
C.
For your roof or floor system read off the
minimum required insulation product
The BCA/NCC specifies the minimum deemed to satisfy performance for roofs and floors dependent upon on the
climate zone your building is in. Locate the climate zone from the following map or refer to abcb.gov.au for more
detailed maps.

STeP B. determine the Thermal
Performance required by the BCA/nCC
Select from either the Floor or Roof System tables.
The energy efficiency provisions for roofing vary
depending on the roof colour in climate zones 1,2
and 3, Table 3.1 below reflects this requirement. For
designs in climate zones 1,2 and 3 it is critical to
obtain solar absorbance values from the roof material
manufacturer in order to determine the required
minimum insulation.
3.1. roof Systems
Please note that the absorbance values for each roof colour class are different between BCA 2010 and NCC 2011.

4. APPlICATIOnS And PrOdUCTS
4.1. Introduction
As most Bradford Insulation under slab products
combine a glasswool base blanket with a facing, a very
wide range of products is available. In order to select
the right products for your application we recommend
that you follow these simple steps:
1. Determine the product required to meet the thermal
requirements of the project using Tables 3.3.1 to 3.4.
2. Select the facing that provides the best level
of performance or aesthetics for your
particular application using Table 4.3.
3. Specify these materials as follows:
Bradford Glasswool [Supertel 50] faced with Bradford
[Thermofoil Medium Duty].
4.3 Available Facings for Under Slab Applications
Anticon products are available in a range of facings as follows:
Facing description
4.2. Material Base Blanket (rMAT ) & Total
System r Values (rT ) - explained
AS/NZS 4859.1: 2002 allows insulation manufacturers
to present the performance in a number of ways.
Two common methods of presenting product
performance are R MAT (the base material thermal
performance) or R T (the total performance of the
product installed in a system). E.g. Anticon 100HP has
a base blanket performance of R2.5 (R MAT ), however,
when installed in a warehouse roof, the total R-Value
of the roof can be calculated as R3.2 (R T ). Bradford
presents its product performance as base blanket
performance R MAT to allow designers the flexibility to
design and specify the most cost effective projects. To
ensure value for money it is important that products
are compared based on the same criteria, e.g. base
material performance or total performance.

4.4. Popular Under Slab Product & Facing Combinations
There are many Bradford Insulation base blanket and facing permutations that can be manufactured. However, the
most applicable and cost effective solutions are as follows:
Application Base Blanket Facing
Car parks where high light reflectivity and high durability
is required.
Supertel or Ultratel glasswool. White Thermoplast
Exposed ceiling where a flat finish is required Supertel or Ultratel glasswool Underslab Premium facing
Car parks where high reflectivity and puncture resistance is required Supertel or Ultratel glasswool. Underslab premium facing
Car parks where high light reflectivity and good acoustic absorption
is required.
Roof insulation where maximum thermal performance is required and
insulation is hidden from view (ie concealed by plasterboard).
Applications where acoustic absorption is critical. Provides low reflectivity,
high durability and relatively flat surface
Chilled beam applications where acoustic absorption is critical and a
premium black finish is required
Applications where low reflectivity and high durability and relatively dark
surface is required.
Car parks which require low reflectivity and high durability, some pillowing
is acceptable.

5.1. General
Bradford Insulation’s under slab products should be
installed by qualified professionals. Care should be
taken in the installation of the insulation to ensure
that sufficient room is provided to allow the insulation
to recover to its design thickness. If the insulation is
compressed the total R-Value will be reduced and the
insulation may not recover to meet the design R-Value
