Foil-Scrim-Kraft facing & Vapor Barrier FSK-716B

FSK-R716A is F/R grade Foil-Scrim-Kraft Facing with 2-way scrim and 60gsm Kraft (F/R treated). All 3 layers laminated together using a flame-retardant adhesive. Foil Scrim Kraft or FSK insulation is a flame retardant, vapor-barrier, and facings for the insulation industry. It is most utilized with duct wrap, duct board and exposed surfaces of HVAC ductworks, exterior walls and ceilings.

  • Foil-Scrim-Kraft facing & Vapor Barrier Introduction

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 Flame-retardant adhesive, it increased tensile strength of FSK, and the Aluminum foil and Kraft paper are firmly bonded.
