Double sided aluminum insulation DFC201 is a medium duty, Housing Grade D/S Foil Insulation.Double sided aluminum 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. Double sided aluminum 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.

Double sided aluminum insulation as Radiant barriers and Reflective insulation work by reflecting radiant heat. It is installed outside the Glass wool, Rock wool, mineral wool, foam insulation materials.Excellent as radiant barriers, flame retardant and vapor barriers can reduce energy loss costs 5% to 10%.
