Radiant Barriers and Reflective Insulation Systems
Double side insulation systems, 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.D/S Foil Insulatio is excellent as radiant barriers, flame retardant and vapor barriers can reduce energy loss costs 5% to 10%.
A medium duty, Housing Grade D/S Foil Insulation.D/S Foil Insulation is made from 2 outer layers of pure aluminum foil and 1 layer thicker natural Kraft paper. These layers are bonded together with polyethylene and reinforced with 3-way fiberglass scrim. D/S 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,Aluminum Foil Insulation is excellent as a vapor barrier for air-conditioning ducts, pipes and vessels.
