Scotch 3311-10a Foil Tape, 2 In. X 10 Yds., Aluminum Backing

Scotch Foil Tape is a conformable, moisture-resistant sealing tape designed for HVAC ductwork, insulation jacketing, and general maintenance repairs. The soft aluminum foil backing flexes to fit irregular surfaces and seams, creating a reliable vapor barrier that helps maintain duct integrity and optimize heating and cooling system performance. Whether you're sealing joints on foil-jacketed insulation, repairing damaged ductwork, or tackling automotive repairs, this tape delivers dependable moisture protection in both professional and DIY applications.

The silver-colored foil finish provides visibility and a reflective surface that highlights sealed areas. Its silicone-treated liner unwinds smoothly to minimize waste and application errors, and the flexible construction makes it easy to apply in tight spaces and around corners where rigid materials cannot reach. This single roll offers 10 yards of sealing capability from a trusted brand.
