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.
