What makes Bradford Black so different?
Bradford Black is approved by the National Asthma Council's Sensitive Choice program, making it suitable for use in homes of asthma and allergy sufferers.
The first thing most people notice about Bradford Black is that it’s white. It’s also fluffy and very soft, like cotton wool.
Installation is easy for homeowners, handymen and builders. The batts are tightly compressed into lightweight packs for easy
transport and storage. They retain their shape and rigidity for easier installation, and are soft to touch.
Bradford Black is manufactured in Australia by CSR Bradford using sustainable recycled glass. Like all products by CSR Bradford, Bradford Black insulation batts comply with all local standards. Click here to find out where to buy Bradford Black.
DIY Installation Guide
Installing Bradford Black is child's play
Bradford Black makes DIY installation easy. Batts are tightly compressed into a lightweight pack for easy transport and storage. The batts retain their shape and rigidity.
What you need
Sharp knife and cutting board
- Step ladder, torch or lamp and kneeling board
- Non-electrical conductive insulation poker (poker can be made using 25mm rod one metre long and two nails about 25mm and 100mm from one end)
Basic rules for ceiling
- Take enough packs into the roof for the whole job.
- Purchase 430mm insulation for 450mm joist centres and 580mm insulation for 600mm centres. For those unsure of their joist centres, 430mm insulation is perforated in the centre to suit both 430mm and 580mm joist centres.
- Stand on ceiling joists only.
- Ensure kneeling board is positioned over at least two ceiling joists.
- Start laying insulation from the furthest point from the manhole.
- Do not block ventilation openings – leave 50mm clearance around chimney from your heater.
- Please refer to plasterboard manufacturers for maximum ceiling load.
Laying Bradford Black ceiling insulation
- Turn off power at the fuse box before commencing the installation.
- Ensure you place a warning tag to prevent power being restored prior to completion of the install.
- Be aware that your electrical appliances will not operate during this time.
- Lay insulation between ceiling joists using the poker to push them into limited access areas.
- Do not leave any gaps between the insulation.
- Fit insulation tightly between joists, but do not compress insulation.
- Push insulation out towards eaves so the end of the first segment is 50mm into the wall plate. Use wooden rod or other non-conductive poker.
- For best results install the insulation with the top surface up. The top surface is that facing the front of the pack.
- Insulation must not be installed in contact with downlights recessed into ceilings. To meet AS3999 in Australian homes a clearance of 25-50mm must be provided around the perimeter of the fitting to help heat dissipation, however the clearance should be as close to 25mm as possible to ensure
maximum insulation performance. To meet NZ4246.1 in New Zealand homes a clearance of 200mm must be provided around the perimeter of the fitting to help heat dissipation, however the clearance should be as close to 200mm as possible to ensure maximum insulation performance.
Electric cables and equipment
- Electric cables and equipment partially or completely covered may overheat and fail.
- Lay insulation with electrical wiring and equipment, such as transformers, on top. For excessive runs covered by insulation seek advice from an electrician as to whether cardboard spacers or similar would be required to allow air circulation.
- Electrical wiring must not be completely surrounded by insulation without prior approval from a licenced electrical contractor. Partially surrounding of electrical wiring is acceptable as long as the wiring has been done in compliance with AS/NZS3000 post 1984.
- For more information regarding the installation of insulation around electrical cables and equipment, please refer to AS3999.
