Foil Duct Tape


Foil Duct Tape  AWF/SFK



JVCC FSK-A FSK (Foil-Scrim-Kraft) Tape is a 3-way fiberglass scrim, dead soft aluminum foil and Kraft paper tape coated with an acrylic adhesive that’s carried on a removable paper release liner (3.2-mil thick). Since the foil is malleable, this tape can conform to curved and other irregular surfaces, maximizing contact with the adhesive for a stronger bond. It has a fast, positive grab to the insulation surface, and can be used as an effective closure system for mineral wool or fiberglass insulation systems that contain foil. JVCC FSK-A FSK tape seals joints and seams on fiberglass duct board with an aluminum face. By providing a vapor barrier, it keeps the integrity of the system strong and intact.
