FSK facing insulation FKSE-7161A is a improved commercial grade Heat-sealing Foil-kraft-scrim Insulation Facing with 3-way scrim and 60gsm Kraft as well as heat-activated polyethylene on its back. No need for extra adhesive when using this foil scrim kraft paper.The thicker Kraft provides neat apperance and enhances tensile strength, tear resistant and durability.
Moisture Barrier: FSK facing acts as a moisture barrier, preventing water vapor from penetrating the insulation material and protecting it from moisture-related damage.
Radiant Heat Reflection: The aluminum foil layer reflects radiant heat, helping to maintain thermal efficiency and temperature control in HVAC systems and insulation applications.
Vapor Retarder: The kraft paper layer acts as a vapor retarder, reducing the transmission of water vapor through the insulation and maintaining indoor air quality.
Duct Insulation: FSK facing is commonly used in HVAC duct insulation to provide thermal insulation, moisture resistance, and protection against radiant heat.
Pipe Insulation: It is also used in pipe insulation applications to enhance thermal performance and prevent condensation on pipes.
Roof Insulation: FSK facing can be applied in roof insulation systems to improve energy efficiency and protect against moisture infiltration.
