Aluminum foil vapor barrier is F/R grade Foil-Scrim-Kraft Facing with 2-way scrim and 60gsm Kraft (F/R treated). Used facing & vapor barrier for duct wrap insulation.
Aluminum foil vapor barrier is a flame retardant, vapor-barrier, and insulation facing for the insulation industry.Foil-scrim-kraft is laminated 5 layers of structure, all 5 layers laminated together using a flame-retardant adhesive. The outer layer is aluminum foil and kraft paper.Middle layer is the glass fiber layer double side coated with flame-retardant adhesive, it increased tensile strength of FSK, and the aluminum foil and kraft paper are firmly bonded.
Aluminum foil vapor barrier protects insulation materials as like as a jacket. Aluminum foil vapor barrier 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: Foil-scrim-kraft, Scrim=Yarn
