Aluminum foil tape is ideal for an array of uses, including general repair, sealing hot and cold air ducts (excellent HVAC tape), duct insulation systems, sealing aluminum, stainless and plastic seams / joints, temporary repair of metal surfaces, copper pipe fixing, etc.
Resists flame, moisture / vapor, UV degradation, odor, weather, some chemicals and smoke transmission. Good for both indoor and outdoor use. Chemically resistant, thermally conductive (helping cooling/heating efficiency), heat and light reflective.
The aluminum tape provides a durable bond at low and high temperatures. Conformable backing and pressure sensitive adhesive means it will adhere properly to a variety of smooth and irregular surfaces.
