FSK aluminum foil tape is designed to seal FSK-facing fiberglass duct board and pipe insulation against moisture and vapor. 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. The combined backing properties result in a strong tape that provides a barrier against vapor.

ALUMINUM 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.

ALUMINUM 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.
