Double Sided Foil Insulation is a flame-retardant CM grade foil Insulation. Double foil insulation is made from 2 outer layers of pure aluminum foil and 1 layer F/R Kraft paper. These layers are bonded together with F/R Glue and reinforced with 3-way fiberglass scrim.
Double Sided Foil Insulation is ideally used as sarking and insulation under roofs, in walls behind cladding or under timber floors, for residential and commercial building. Combining with glass-wool /rockwool/ mineral wool/ foam insulation, it is excellent as a vapor barrier and reflective aluminum foil insulation for air-conditioning ducts, pipes and vessels.
Double Sided Foil Insulation systems as Radiant barriers and Reflective insulation work by reflecting radiant heat. It is excellent as radiant barriers, flame retardant and vapor barriers can reduce energy loss costs 5% to 10%.
