FSK Insulation Tape

FSK insulation tape is designed to seal foil scrim kraft facing fiberglass duct board and pipe insulation against moisture and vapor. FSK insulation jacketing tapes can also be used for patching rips and tears in foil-facing insulation ,used with fiberglass duct wrap for added strength.

Foil-scrim-kraft (FSK) is a flame retardant, vapor-barrier,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 insulation 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:

Foil scrim kraft insulation jacketing tape is used for sealing HVAC duct seams and joints where FSK is the basic insulation facing.Used for sealing and patching FSK ductwork and insulation and 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.
