Aluminum has a sturdy thickness, and the wax paper peels easily off the Adhesive Backing of the Aluminum Foil Tape. Great Adhesion -- the Aluminum Foil Tape sticks to the ductwork surfaces with a solid grip. I bought the 3-inch wide tape and recommend it for the overlap needed to join two surfaces. Also an Excellent Value at under 10 cents per foot.
