Foil scrim kraft insulation consists of 15u foil and 2-way scrim (5x5mm spacing) with heat-activated polyethylene on its back. Good corrosion-resistance and abrasive-resistance. It is a premium grade Heat Sealing FSK Insulation facing,it is both a vapor barrier and a flame retardant.

FSK faced insulation has a vapor barrier or a vapor retarder (the facing) that helps prevent moisture from moving from one space to another. The facing also helps protect the surface, hold the insulation together and fasten the material to building components.

Foil scrim kraft insulation is suitable for in-line lamination with insulation materials by heating. No need applying extra adhesive.Foil Scrim Kraft Insulation is widely used in construction, water-proofing, reinforcing and coating applications.
