Secure and seal the edges of your insulation products with this heavy-duty RESISTO® tape. Made of durable materials, it seals seams of reflective insulation materials to increase their effectiveness. By closing the juncture between two insulation pieces, the tape helps prevent water and heat from passing through the seams. This polyethylene tape features a single-coat, synthetic rubber adhesive for maximum stickiness. Sturdiness and longevity come from the strong polyethylene backing that seals vinyl joints on indoor insulation. The white tape design works with AYR-FOIL™ insulation products. One roll of this joint-sealing tape for aluminum foil insulation measures 2 in W x 180 ft L. A measuring tape and utility knife are all you need to apply this adhesive easily and quickly.
