A improved commercial grade Heat-sealing Foil-kraft-scrim Facing with 3-way scrim and 60gsm Kraft as well as heat-activated polyethylene on its back. The thicker Kraft provides neat apperance and enhances tensile strength, tear resistant and durability. It is mainly used under roof decking, under attic rafters, over existing attic insulation, in floors, walls and crawl spaces, and in industrial and commercial buildings as radiant barrier to block radiant heat coming ductworks and cold rooms combining with traditional insulation such as glass wool, rock wool, phenolic panel, PU foam.
The Heat-sealing Foil-Kraft-Scrim Facing is a industrial strength foil scrim kraft insulation. It is widely used in construction, water-proofing, reinforcing and coating applications. No need for extra adhesive when using this foil scrim kraft paper.
