D/S Reflective Aluminum Foil Insulation is installed outside the Glass wool, Rock wool, mineral wool, foam insulation materials. It can reduce energy loss costs 5% to 10%.
Double sided aluminum foil insulation is a light duty, utility Grade D/S Foil Insulation. It 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, it is excellent as a vapor barrier for air-conditioning ducts, pipes and vessels.
