D/S Reflective Aluminum Foil Insulation

A light duty, Eco grade Double sided Reflective Aluminum Foil Insulation.Reflective Aluminum Foil Insulation is made from 1 outer layer of pure aluminum foil and 1 outer layer of metalized polyester film as well as 1 layer recycled Kraft paper. These layers and bonded together with polyethylene and reinforced with 3-way fiberglass scrim. D/S Reflective Aluminum Foil Insulation is ideally used as sealing and insulation under roofs, in walls behind cladding or under timber floors, for residential and commercial building. Combining with glass wool / rock wool / mineral wool / foam insulation, it is excellent as a vapor barrier for air-conditioning ducts, pipes and vessels.
