Insulation Facing Description

 

Foil faced 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 Foil-Scrim-Kraft, and the Aluminum foil and Kraft paper are firmly bonded.

Using foil-faced insulation with a vapor barrier can help improve the overall energy efficiency of a building by reducing heat transfer and preventing moisture-related issues. It can also help maintain indoor comfort levels by creating a more consistent temperature environment. The foil facing of the insulation also provides reflective properties, which can help improve the insulation's thermal performance by reflecting radiant heat.

Foil-faced insulation vapor barriers are commonly used in walls, roofs, floors, and HVAC systems to provide thermal insulation and moisture control. They are suitable for both residential and commercial buildings. Foil faced 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.
