Frequently Asked Questions
Roofing insulation is a barrier layer that is installed under a rooftop. It reduces and slows heat transfer, helping keep the interior of the building warmer in winter and cooler in summer.
Not only does insulating your roof enhance comfort inside the home or other premises, but it also improves the building’s energy efficiency and can actively reduce energy bills.
Installing a COLORBOND® roof effectively requires items including self-drilling screws that meet Australian standard AS3566.1 Class 3 (or above) and which feature a neoprene or EPDM sealing washer. Select screws that are painted in the exact COLORBOND® colour as your rooftop sheeting to ensure a seamless finish.
