Use this RESISTO® tape to seal the surfaces of indoor construction products for a secure finish. Install the reflective insulation tape with the use of a utility knife and a tape measure for fast and easy application. It's specifically designed to use with AYR-FOIL™ products to seal metallic surface joints. Make sure the surface is dry and clean and free of any debris before applying the 2-inch aluminum tape. A single roll measures 150 ft in length. It serves as a vapour barrier to regulate the amount of moisture that passes through surrounding surfaces, such as insulation. This barrier helps minimize the transfer of humidity to protect the insulation. A silicone release film rests over the sticky side of the tape to maintain its adhesion and to provide a mess-free installation.
