Foil Scrim Kraft Facing Vapor Barrier

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.
