Aluminum tape is a durable tape that belongs to the large family of pressure sensitive tapes. Made of aluminum foil and adhesives, it conforms to uneven surfaces and has a high resistance to moisture, vapour, and temperature fluctuations. Aluminum foil tape can be used under extreme temperatures, both hot and cold and is flame resistant, which adds to its flexibility of use.It is commonly used in HVAC (heating, ventilation, and air conditioning) systems to seal and secure joints, seams, and connections in the ductwork.
