Foilboard GREEN 20 mm
Heat Flow out (Winter) : RT2.2
Heat Flow in (Summer) : RT2.0
Foilboard® Insulation Panel will not sag and leave uninsulated pockets that can reduce R Values. Installed correctly, the full ‘R’ value will last the life of the building. Once fixed in place, it will maintain complete coverage around the building and as it covers the frame, there can be no loss of effectiveness via thermal bridging through the frame.
RT - R-values displayed are "total system R-values", as required by the Energy Provisions of the Building Code of Australia.
