Aluminum tape

Description

An adhesive tape that is back by a metallic foil. The flexible metal allows the tape to conform to curves and uneven surfaces. Aluminum tape is reflective, UV resistant and thermally conductive. It is often used to seal off vapors in fiberglass duct board, sheet metal ducts and other HVAC conduits. It typically contains an acrylic adhesive that adheres well in a wide range of temperatures and humidities (note: some tapes have rubber-based adhesives).
