This is a 9 mil cast polyethylene tape with a high-tack synthetic rubber adhesive, sold in a 4 in. by 180 ft. roll. It is built to seal seams and edges of 10 mil or thicker polyethylene vapor barriers in crawl spaces, basements and under-slab or insulation jobs. Its 126 oz/in. adhesion to steel and 25 lb/in. tensile strength put it in the heavy-duty class, and it resists moisture, cold and UV. Compared with general-purpose duct or sheathing tapes, it is thicker and made to bond to PE film rather than to paper or metal.

This heavy duty vapor barrier sealing tape is made from a cast polyethylene film coated with a high tack rubber adhesive. It is 9 mil thick and comes on a roll 4 in. wide and 180 ft. long.
The tape resists moisture, cold temperature and UV light. It works with most polyethylene vapor barrier films that are 10 mil or thicker, including Husky Yellow Guard Vapor Barrier and other extruded polyethylene films.
It is used to seal seams in crawl space vapor barriers, moisture barriers, vapor retarders and basement vapor barriers. For best performance, use it with a 10 mil or thicker vapor barrier.
