Description & Application
A light duty, utility 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 3-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 for air-conditioning ducts, pipes and vessels.
