3M 425 Aluminum Foil Tape is a 4.6 mil dead-soft aluminum foil tape with an acrylic adhesive backing, offered here as a single 1-inch-wide by 60-yard roll. Its conformable foil construction delivers thermal conductivity, flame resistance, UV resistance, and reflectivity, making it one of the most specified foil tapes for demanding sealing and insulation work.
This tape is a standard choice for HVAC duct sealing, insulation facing, thermal jacketing, and moisture barrier applications in commercial construction, mechanical contracting, and industrial manufacturing. It bonds reliably to irregular or curved surfaces and holds up in environments subject to heat, moisture, and prolonged UV exposure.
The tape meets UL 723 and UL 764c and carries a Class L File R 7311 listing, satisfying code compliance requirements for many commercial and industrial installations. Sold as one individual roll per pack.
