FSK foil scrim kraft facing FKSE-7511B is a utility grade Heat-sealing Foil-kraft-scrim Facing with 2-way scrim and 50gsm Kraft as well as heat-activated polyethylene on its back. The thicker Kraft provides neat apperance and enhances tensile strength, tear resistant and durability.

FSK foil scrim kraft facing 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.
