JM Launches Seal-It

February 8, 2007

Johns Manville has launched a new line of housewrap tape and flashings called Seal-It, which is specifically formulated to adhere to Gorilla Wrap, JM’s housewrap. Seal-It enhances the building envelope by tightly sealing housewrap seams and window and door enclosures. The product consists of a single-coated polyester film with an aggressive, tacky acrylic adhesive that is highly effective in creating durable, long-lasting seams and seals that reduce air infiltration and increase energy efficiency. Seal-It Housewrap Tape also has a unique serrated edge for easy tear.
Seal-It makes Gorilla Wrap, a non-perforated, nonwoven polymeric housewrap material that already provides superior air resistance that is eight times better than the current industry-leading housewrap, even more stable and strong by creating a greater weather-resistant air and vapor barrier system with ultra-low air infiltration. Gorilla Wrap’s superior strength, with a tear resistance that is 300% higher than the leading housewrap, makes it one of the most durable housewrap products on the market.
