Insulation Facing Description

 

Foil Scrim Kraft (FSK) is a high-quality insulation facing material engineered for superior thermal insulation, moisture control, and durability. By combining the reflective properties of aluminum foil, the strength of kraft paper, and the reinforcement of fiberglass scrim, Foil Scrim Kraft insulation delivers excellent performance in HVAC, building, and metal structure applications.

The foil layer acts as a radiant barrier, reflecting heat to enhance energy efficiency in heating and cooling systems. Meanwhile, the kraft paper and scrim reinforcement provide dimensional stability, tear resistance, and long-lasting protection during installation and service life.

Tape Applications:

Foil Scrim Kraft is a trusted solution across various construction and industrial settings where thermal management and moisture protection are paramount:

  • HVAC Systems: It is used extensively to wrap and insulate HVAC ducts and pipes, improving thermal efficiency and preventing condensation and air leaks.
  • Building Envelope Insulation: FSK Insulation is applied as a facing for various insulation types in walls, ceilings, and roofs in general building construction.
  • Metal Building Insulation: It is widely used to insulate metal buildings, primarily to prevent condensation and improve thermal regulation.
  • Vapor Barrier and Sealing: It acts as a primary foil scrim kraft vapor barrier on surfaces requiring protection against moisture transmission.
  • Industrial Packaging: The material is occasionally used in industrial packaging solutions where both moisture control and insulation are necessary to protect goods.

Tape Features:

  • High Reflectivity: The aluminum foil layer reflects radiant heat, improving thermal efficiency and energy savings.
  • Effective Vapor Barrier: Acts as a FSK vapor barrier that prevents moisture intrusion and protects insulation from condensation and mold.
  • Enhanced Strength: The 3-way fiberglass scrim provides reinforcement, making it resistant to tearing, punctures, and installation damage.
  • Durable Construction: The combination of foil, scrim, and 50gsm kraft paper ensures superior performance in demanding environments.
  • Easy Installation: The heat-activated polyethylene backing eliminates the need for additional adhesives.
  • Multi-Functional: Serves as both a thermal insulation facing and a moisture barrier for a wide range of insulation systems.
