FSK Foil Faced Insulation is composed of a 15u aluminum foil laminated to a 2-way fiberglass scrim (5x5mm spacing) with a heat-activated polyethylene backing. This robust construction ensures excellent corrosion resistance, high durability, and effective thermal insulation. The reflective foil surface helps to prevent heat loss, while the scrim provides added strength and resistance to abrasion.
FSK Faced Insulation, also known as Foil Scrim Kraft facing, is designed for a wide range of thermal insulation and vapor barrier applications. This versatile material is a go-to choice for improving energy efficiency and durability in construction projects.
