Gold Ceiling Insulation

What you need

Tools

• Sharp knife and cutting board

For Ceilings

• 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. 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 Gold 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 a wooden rod or another non-conductive poker. In a retrofit, it is best practice for the top plate to have 50% coverage and a 25mm clearance between the insulation and any roofing material.
• 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 NZS 4246.1 in New Zealand homes a clearance of 100mm (unless otherwise indicated by luminaire manufacturer) must be provided around the perimeter of the fitting to help heat dissipation, however the clearance should be as close to 100mm as possible to ensure maximum insulation performance.

Product performance

• After unpacking, the product is designed to achieve its nominal stabilised thickness within 24 hours of installation.
• The performance of this product may be reduced if stored for too long in its compression packaging.
• The total R-Value depends on installation and may be greater than or less than the R-Value of the product.
• The material R-Value represented on this pack was determined at a mean temperature of 15°C for products sold in New Zealand, as per AS/NZS4859.1.
• The material R-Value is independent of the heat flow direction (the same R-Value is achieved in summer and winter conditions).

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.
