FSK Insulation Facing enhances the thermal performance of insulation by reflecting radiant heat, helping to maintain temperature control and energy efficiency in HVAC systems. The foil layer of FSK Facing acts as a vapor barrier, preventing water vapor from permeating the insulation. This helps to prevent mold growth and maintain the effectiveness of the insulation. The combination of foil, scrim, and kraft paper layers provides FSK Facing with durability and resistance to tearing, puncturing, and other physical damage. FSK Insulation Facing is compatible with a wide range of insulation materials, including fiberglass, mineral wool, and foam insulation boards. The kraft paper layer in FSK Facing adds a level of fire resistance to the material, making it suitable for applications where fire safety is a concern. It is easy to install and can be applied to insulation materials using adhesive or mechanical fasteners. The Facing can help reduce noise transmission through insulation systems, contributing to soundproofing in addition to thermal insulation.
