FSK-R716A is a Fire resistant grade Foil-Scrim-Kraft facing with 3-way scrim and 60gsm Kraft, 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: Foil-scrim-kraft, Scrim=Yarn
FSK as a laminated insulation facing protects insulation materials as like as a jacket. FSK is most commonly used to exposed surfaces of Duct wrap, HVAC Ductwork, Exterior wall insulation, Metal building insulation, Pipeline insulation, Hot water tank insulation.
FSK is laminated 5 layers of structure, the outer layer is Aluminum foil and 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.
