3M 1581a-silver_3x60 Aluminum Foil Tape Silver 3 Inches X 60 Yd

Product Description

The 3M 1581a-silver_3x60 is a silver aluminum foil tape designed for HVAC duct sealing applications. This tape measures 3 inches wide and 60 yards long, giving technicians a generous supply for large jobs. The aluminum foil backing is 4 mil thick, providing strength and resistance to tearing during installation. HVAC professionals rely on this tape for sealing rigid duct board, flexible duct connections, and fiberglass duct board systems. It meets UL 181A-P and UL 181B-FX listings, which are required standards for duct sealing materials used in pressure-sensitive tape applications on rigid fiberglass ducts and flexible air ducts. It also carries ULC S102 listing for Canadian fire hazard classification compliance. This makes it a code-compliant choice for commercial and residential HVAC work in both the United States and Canada. The aluminum foil construction handles high heat and high humidity environments without breaking down. This makes it suitable for mechanical rooms, attic spaces, crawlspaces, and other demanding installation areas where standard tapes may fail. The tape also functions as an effective vapor barrier when applied to reinforced fiberglass duct board, helping prevent moisture infiltration that can degrade duct systems over time. One practical advantage for field technicians is that this tape is hand-tearable. Workers can cut it to length without needing scissors or a utility knife, speeding up installation on the job. The silver finish integrates cleanly with standard duct materials for a professional appearance. HVAC installers, sheet metal contractors, and mechanical insulation workers will find this tape a reliable option for both new construction and retrofit duct sealing projects.

• UL 181A-P and UL 181B-FX listed for use on rigid and flexible air duct systems
