Product Description

Polyken/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).
