Aluminum duct tape, also known as aluminum foil tape, is a type of adhesive tape that is specifically designed for use in HVAC (heating, ventilation, and air conditioning) systems and ductwork. Thickness 25um normal aluminum foil backing, coated with Acrylic adhesive, protected by an easy-release silicone paper liner.

Aluminum duct tape feature extreme performance adhesives formulated to work in a wide range of cold and hot temperatures. These tapes are commonly used for sealing and patching joints, seams, and connections in ductwork to prevent air leaks and to provide thermal insulation. It is heat-resistant and can withstand a wide range of temperatures, making it suitable for use in both residential and commercial HVAC systems. Aluminum duct tape is also known for its durability and ability to adhere to a variety of surfaces, making it a popular choice for HVAC professionals and homeowners alike.
