Foil scrim kraft facing is a premium grade laminated insulation facing protects insulation materials as like as a jacket.
Foil scrim kraft facing 718B mainly used as a facing & vapor barrier for glasswool / rockwool / foam duct wrap insulation, also a good choice for radiant barrier applications because of its low emissivity.
FSK is a laminated insulation facing protects insulation materials as like as a jacket. It is most commonly used to exposed surfaces of Duct wrap, HVAC Ductwork, Exterior wall insulation, Metal building insulation, Pipeline insulation, Hot water tank insulation.
Foil Scrim Kraft Facing is laminated 5 layers of structure, the outer layer is Aluminum foil and 80gsm Kraft paper.The middle layer is the glass fiber layer double side coated with adhesive, it increased tensile strength of FSK, and the aluminum foil and kraft paper are firmly bonded.
FSK: Foil-scrim-kraft, Scrim=Yarn
