Double sided reflective foil insulation as radiant barriers and reflective insulation work by reflecting radiant heat. D/S Reflective Aluminum foil radiant barriers are installed outside the glass wool, rock wool, mineral wool, foam insulation materials.

Flame-retardant CM grade foil insulation. Double sided reflective 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 2-way fiberglass scrim. It 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 foil insulation for air-conditioning ducts, pipes and vessels.
