Foil-Scrim-Kraft facing & Vapor Barrier FSK-718B

FSK-718B Foil-Scrim-Kraft facing & Vapor Barrier is a premium grade Foil-Scrim-Kraft facing with 2-way scrim and 80gsm 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.

  • 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.

Foil-Scrim-Kraft Facing 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.

Foil Scrim Kraft Vapor Barrier 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.
