Insulating your windows doesn't have to be a chore! Using the Scotch Outdoor Window Film Mounting Tape makes it a lot easier. All you have to do is peel away the disposable liner on one side and mount the tape where it is needed. Then, peel off the other liner and apply the film. That's all there is to it, and the tape stays stuck until you take it off. Each roll contains an ample 500" of tape, so you don't have to worry about running out. Get some Scotch Outdoor Window Film Mounting Tape and get ready for winter!
