FSK aluminum foil tape is designed to seal FSK-facing fiberglass duct board and pipe insulation against moisture and vapor. They provide an excellent barrier to vapor and conform to irregular surfaces.The reinforced aluminum foil tape can also be used for patching rips and tears in foil-facing insulation and can be used with fiberglass duct wrap for added strength.

Foil-scrim-kraft (FSK) is a flame retardant, vapor-barrier, and it is one of the most commonly used facings in the insulation industry. High-strength foil-scrim-kraft paper all laminated together using a flame-retardant adhesive.FSK aluminum foil tape has a combined backing of aluminum foil, kraft paper, and fiberglass scrim. It offers high puncture and tear resistance, ensuring a long life and durability in various conditions and applications.The combined backing properties result in a strong tape that provides a barrier against vapor.

Aluminium Foil Tape Applications:

FSK aluminum foil tape is used for sealing HVAC duct seams and joints where FSK is the basic insulation facing, provides a finished look for exposed HVAC systems.

Aluminium Foil Tape Features:

  • Scrim layer bends with the primary facing providing integrity to the insulation and a strong, finished, appearance.
  • Release liner provides easy removal for efficient application on the job site.
  • High-tack synthetic rubber adhesive forms an instant bond.
  • Moisture-, mold-, and UV-resistant design.
