D/S Reflective Aluminum Foil Insulation
Description & Application
CM Grade D/S Foil Insulation. It is made from 2 outer layers of pure aluminum foil and 1 layer natural Kraft paper. These layers are bonded together with polyethylene 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 glasswool / rockwool / mineral wool / foam insulation, it is excellent as a vapor barrier and reflective foil insulation for air-conditioning ducts, pipes and vessels.
