Description
Product Summary
Fasson 0800 is the everyday foil tape installers reach for when a duct seam needs to be sealed and pass inspection. The 2 mil aluminum foil facestock carries a clear antimicrobial acrylic adhesive and is UL 181A-P and UL 181B-FX listed, so it is approved for sealing joints and seams on rigid fiberglass duct board and on flexible air duct, and it works just as well on sheet metal duct and foil-faced FSK board.
Each roll is 2.5 inches wide and 60 yards long. Apply it above 50°F to clean, dry surfaces and press it down firmly with a squeegee; once bonded it holds through service temperatures up to 350°F and resists UV, which makes it a good fit for attics, mechanical rooms and rooftop duct runs. Fasson backs this tape with a 20 year limited warranty.
