1. INTRODUCTION 

DesignSmart 

Bradford’s new DesignSmart program has been developed 

to help our customers create smarter, faster and more cost 

effective designs. 

This brochure has been developed to assist Architects, 

Designers and Builders to meet the insulation requirements 

of the Building Code of Australia (BCA) for key applications 

within factories and warehouses. It summarises the key 

information regarding the requirements of the BCA and 

allows you to quickly and easily select the most cost 

effective products that meet the minimum requirements 

for these applications. 

For further specification assistance the DesignSmart section 

of our website includes full details of regulations, specification 

calculators, product brochures, data sheets, MSDSs and 

much more information to make your job even easier.

Insulation in Factories & Warehouses 

Manufacturing and the storage and distribution of finished 

goods are key elements of a healthy economy. The requirements 

of this sector are extremely diverse. From high tech ‘clean’ 

manufacturing environments to storage of refrigerated or 

flammable goods, each application needs careful consideration 

to ensure all requirements are met. 

This must be balanced with the wellbeing and comfort of 

the personnel in these facilities to ensure optimum levels of 

productivity and job satisfaction. 

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. 

Where the BCA does not specifically cover factories and 

warehouses – such as sound insulation provisions – there 

is a strong argument to support the voluntary inclusion of 

high standard sound insulation to ensure the health and 

safety of personnel. 


Fortunately, bulk insulation products used to achieve wall 

insulation energy efficiency provisions also provide excellent 

acoustic protection. This is not the case for reflective foil 

laminates or closed cell foam insulation products used in 

walls – nor do they meet strict non-combustibility standards. 

General 

Insulation used to meet BCA Volume 1 Class 2-9 Part J1 

Energy Efficiency Provisions must comply with AS/NZS 

4859.1 amdt1 and insulation for all purposes should be 

installed so that it: 

1. abuts or overlaps adjoining insulation; and 

2. forms a continuous barrier with ceilings, walls, bulkheads, 

floors and the like that inherently contribute to the thermal, 

acoustic or fire barrier; and 

3. does not affect the safe or effective operation of a service 

or fitting 

Bulk insulation must: 

1. maintain its position and thickness, other than where it 

crosses roof battens, water pipes, electrical cabling or the 

like; and 

2. extend to the perimeter member by not less than 50mm 

in ceilings where there is no wall insulation; and 

3. not be installed over old wiring installed prior to 1989 

Installation must comply with AS3000. 

Reflective insulation must be installed: 

1. with the necessary non-ventilated airspace to achieve the 

required R-Value between a reflective side and a building 

lining or cladding; and 

2. closely fitted against any penetration, door or window 

opening: and 

3. adequately supported by framing members; and 

4. so that each adjoining sheet is either overlapped not 

less than 50mm or taped together and when attached 

to bulk insulation must be installed with sufficient sag 

to allow the insulation to recover to its normal thickness 

and not pulled tight

2. AppLICABLE BUILDING REGULATIONS 

Building Code of Australia – 2010 

volume One Class 2 to Class 9 Buildings 

The following list is a summary of the applicable building regulations with respect to this building type. For full details of the 

building regulations please refer to the Building Code of Australia. Bradford also 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.

CLASS 8 – FACTORy

3. ENERGy EFFICIENCy (Section J) 

Energy Efficiency provisions are included in Volume 1 of the 

BCA for class 2 to 9 buildings. Please refer to BCA Section J1 

for specific application notes. 

These represent only minimum acceptable energy efficiency 

standards – eliminating worst practice – and do not necessarily 

demonstrate optimum levels of insulation. 

Bradford recommends an increase in insulation performance 

over and above BCA 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 short term return 

on installation costs. The benefits of reduced energy costs can be 

passed on to building occupants and contribute to reduction of 

greenhouse gases. 

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 below:

4. INSULATION pRODUCT STANDARD AS/NZS4859 

AS/NZS4859.1: 2002 amended Dec 2006 “Materials for the 

thermal insulation of buildings” is called up in the BCA. 

This standard sets testing and labelling requirements to ensure 

R-Value actual performance is as per manufacturers claims. 

Not all insulation products will readily meet thermal, fire and 

acoustic performance claims. Always ask for tested and certified 

insulation product documentation. 

5. MATERIAL vS TOTAL R-vALUES 

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 (R T ) 


an insulation product must demonstrate compliance with 

aS/nZS4859.1 to meet the BCa. 

Compliance documentation to AS/NZS4859.1: 2002 for all 

Bradford products is available from your Bradford representative. 

The 2006 amendment provides details of how to derate 

reflective foil products for dust and other factors. 

can be calculated as R3.2 for summer and R2.9 in winter. 

Bradford presents its product performance as base blanket 

performance R MAT to allow designers flexibility to design and 

specify the most cost effective projects. To ensure value for 

money ensure products are compared based on the same criteria 

e.g. base material performance or total application performance.

6. SOUND INSULATION 

While the BCA does not make specific provisions for the sound 

insulation of factories and warehouses, consideration should 

be given to the potential for noise entering the buildings and 

the need to control noise which may be generating by the 

manufacturing processes. 

Particular consideration should be given to the following areas: 

• External noise entering through external walls 

• Rain noise on the roof which may make effective 

communication in the building difficult 

• Noise from the manufacturing area entering 

administration areas 

• Noise from the HVAC system 

ExTERNAL NOISE 

Walls 

Bradford Insulation products will provide acoustic benefits 

as well as meeting thermal requirements. For details of noise 

transmission losses please refer to the Bradford Insulation 

technical manual. 

Roofs 

Bradford Anticon fixed under metal roofs will greatly reduce 

rain noise entering the building. Performance can be enhanced 

by using acoustic material overlay over ceilings. 

INTERNAL NOISE 

Partition walls 

Bradford Insulation recommends a minimum Rw+Ctr of 

45 or Rw45 in QLD and NT for partition walls between 

manufacturing and administration areas which can be 

achieved using a variety of wall systems including either 

Bradford Partition Batts or Bradford SoundScreen. 

For quiet zones such as training facilities needing a higher 

level of performance we recommend Rw+Ctr of 50 or Rw50 

in QLD and NT. 

Bradford offers an excellent range of quality acoustic insulation products including: 

Bradford Glasswool Partition Batts 

50mm, 75mm, 110m and 

165mm 

Bradford Rockwool Partition Batts 45mm Premium grade partition batts 

Bradford Soundscreen 60mm, 75mm, 88mm For use in walls, ceilings or floors 


HVaC Systems 

Fan noise from HVAC can significantly add to the ambient 

sound level. Care must be taken to ensure that the fixed 

ductwork is adequately insulated internally down stream of the 

fan units. Bradford Supertel with an appropriate facing such as 

Ultraphon or Acoustituff provide an easily cleanable solution 

with excellent sound absorption properties. 

Reverberation 

Attention should also be given to reverberation from noise 

sources within the building which is often fitted out with hard 

durable surfaces. Absorptive surfaces such as acoustic baffles and 

acoustic wall linings can significantly reduce reverberation. 

Individual production processes may require specific acoustic 

enclosures to ensure the protection and safety pf personnel 

working on or near the equipment. Your Bradford technical 

team can advise you on systems to achieve the required acoustic 

performance for your project. 

SOUND INSULATION pRODUCTS 

To ensure that Bradford products provide stated acoustic 

performance Bradford has embarked on a program to 

manufacture its acoustic products to conform to AS/ 

NZS4859.1. This standard refers to the method of testing and 

labeling a product’s thermal performance, however, this standard 

can also be used to control product consistency for acoustic 

performance. 

The thermal and acoustic performance of a product is directly 

linked by controlling 3 key parameters; density, thickness and 

fibre size. By specifying Bradford thermally rated products for 

acoustic applications, a consumer is ensuring an Australian 

Standard is employed which sets controls on density, thickness 

and fibre size and hence ultimately ensures consistent acoustic 

performance. 

Currently there is no Australian Standard for acoustic insulation 

materials and it is up to the individual manufacturers quality 

control program to achieve the acoustic rating. Bradford ensures 

acoustic performance by strictly adhering to an established 

Australian Standard.

All Bradford glasswool and rockwool products offer acoustic benefits with a wide range of specialty facings available and fully tested by Bradford. For a detailed list 

of wall, ceiling and floor systems for partition walls please refer to the Bradford Acoustistar manual. For detailed information of HVAC systems, including NRC 

values, performance and details of available facings please refer to the Bradford Acoustic Design Guide.

7. FIRE RESISTANCE 

The BCA details comprehensive fire safety requirements for Class 2,3,5,6,7,8, and 9 buildings depending on the number of storeys. 

Type of Construction Required 

Rise in Storeys Class of Building: 7 & 8 

4 or more A 

3 B 

2 C 

1 C 

Spec C1.1-3 of the BCA outlines the detailed building 

requirements for each of the types of construction. For 

required FRL levels refer to BCA C1.1-3. 

The BCA requires all types of A & B buildings with fire rated 

walls to be of non-combustible construction. This means that 

insulation must be rated non-combustible to AS1530.1 

Bradford Insulation would argue there should be no 

compromise on the protection of students and staff 

against fire - specifiers should favour products that are 

non-combustible. 

The relevant factors for insulation products are: 

1. non-combustibility 

An insulation product is deemed “non-combustible” 

if it passes AS1530.1 

Bradford supplies a range of non-combustible products. For 

further information on non combustibility of our products 

contact Bradford Insulation. Bradford can supply other 

insulation products dependent on your state location, such as 

polyester, Thermofoil Board, polystyrene and FR Armaflex, 

however, please note that these products will not meet BCA 

non-combustible requirements. Check with your local Bradford 

office for your specific insulation product availability. 

FIRE pROTECTION INSULATION pRODUCTS 

Product Size application 

Please note that FireSeal products must be installed at 15% compression to achieve fire resistant properties. For further information on fire protection please 

refer to the Bradford Fire Protection Design Guide. 


Non-combustibility compliance test certificates are available 

on request from your Bradford representative. 

2. General Fire Hazard Properties 

Most Bradford glasswool and rockwool unfaced products 

achieve a 4 zeros rating when tested to AS1530.3 and so not 

only comfortably meet any BCA requirements but also 

provide the best possible fire resistance properties. 

For specific product details refer to the relevant Bradford 

Product Data Sheets. 

Sarking-type materials i.e. reflective foil, require a Flammability 

Index of not more than 5. Bradford EnviroSeal and Thermofoil 

reflective foil products meet these requirements. 

3. Ductwork 

Air-conditioning ductwork must comply with: 

a) Spread-of-Flame not greater than 0, Smoke-Developed 

not greater than 3 when tested to AS1530.3 

b) UL181 Burning test 

Bradford flexible and rigid glasswool or rockwool insulation 

meet these requirements for ductwork insulation. 

CONSTRUCTION IN BUSH FIRE pRONE 

AREAS 

In general Bradford recommends the use of non-combustible 

insulation in the ceiling and walls. 

The use of premium grade Bradford Rockwool FireSeal is recommended for use in areas where the protection of life in the event 

of fire is paramount. All Bradford FireSeal products pass AS1530.1 for non-combustibility. 

Bradford FireSeal Party Wall Batts 1500x168x100mm For sealing gaps above fire rated walls 

Bradford Fire Damper Strips 750x225x13mm 

Bradford FireSeal Batts 75 and 115mm 

For installation around wall and floor penetrations - is also available 

Alfoil wrapped 

For additional fire protection in walls, floor or ceiling insulation 

applications such as behind kitchen areas

8. OCCUpATIONAL HEALTH & SAFETy 

Glasswool and rockwool insulation products are excellent 

insulation materials and are fully safe to use under all 

conditions. Both insulation materials have been in world wide 

use for over 70 years, and during that time their manufacture 

and use have been extensively monitored and researched. 

Bradford glasswool and rockwool products are manufactured 

using the latest FBS-1 biosoluble technology and are not 

classified as hazardous according to the criteria of the ASCC 

(Formerly NOHSC) guidelines. 

Extensive research has been conducted on internal ductliners 

and ceiling insulation and the use of glasswool or rockwool 

in these applications has not been found to contribute any 

detectable increase in fibre counts. 

Detailed information on health & safety is contained in the 

MSDS & ICANZ (Insulation Council of Australian & 

New Zealand) literature enclosed. 

HANDLING COMFORT 


To make the installation of glasswool and rockwool even 

easier, Bradford has developed ComfortSleeve. 

Bradford ComfortSleeve kits are available from selected 

trade outlets including Gyprock Trade Centres.
