AtticFoil foil tape is constructed with a strong adhesive and the same inner scrim as our foil products. The tape has a peel off paper backing to make installation easy, plus this tape cannot tear! We use an acrylic adhesive too, so that means this tape will not dry out like duct tape will. Foil tape is great for seaming, joining large pieces together, repairing cut/damaged insulation, and so much more!
