Nashua Heavy Duty FoilMastic Butyl Rubber Tape (360-45): 4 in. (96mm actual) x 30 ft. (Silver)

Nashua 360-45 Heavy Duty FoilMastic Butyl Rubber Tape is a printed, 2 mil dead-soft aluminum foil backing with a 43 mil butyl rubber mastic adhesive. It is a waterproofing repair tape used for indoor or outdoor sealing of low, medium & high-pressure HVAC duct systems (includes: metal duct, fiberglass duct and flexible duct systems). It seals cracks and seams in gutters, roof alleys, eaves, hips and ridges. Seal around chimneys and vent stacks; rooftop duct systems; and leaks in vans, cars and trucks. Also used for mobile home repair. Repair gouges, rips, tears in metal panels of trailers, shipping containers and metal buildings. Use duct mastic to mend poorly sealed connections; improve indoor air quality (since fewer pollutants circulating); lower utility bills; and burn fewer fossil fuels.

Please note that Nashua 360-45 and Polyken 360-45 are the same product manufactured by Berry Plastics. Therefore the tape roll core may be branded with Nashua or Polyken, depending on current inventory.
