Gorilla Wrap Housewrap from Johns Manville Recognized As Industry Innovation With American Building Product Award.

DENVER -- Gorilla Wrap[TM] Translucent Housewrap from Johns Manville today received from HOME Magazine an American Building Product Award for product innovation and durability. The award was presented at the International Builders' Show in Orlando. For the 11th consecutive year, HOME Magazine editors selected the year's best new American building products, this year honoring 13 products.

Gorilla Wrap is a non-perforated, non-woven polymeric housewrap material that decreases air infiltration resulting in increased energy efficiency and maximum moisture control. Gorilla Wrap's superior strength, with a tear resistance that is 300 percent higher than the leading housewrap, makes it easier to handle on the job site, making Gorilla Wrap one of the most durable housewrap products on the market.

"We are honored to receive this prestigious award from HOME Magazine," said Kelly Kambs, global market development manager of Johns Manville's Engineered Products Group. "Gorilla Wrap is easier for builders to work with because of its tear strength. Gorilla Wrap is translucent, which makes installation easier and faster because contractors can see studs, nails and windows on the home framing beneath the housewrap. Home buyers appreciate Gorilla Wrap's superior air resistance, which is eight times better than the current industry-leading housewrap, helping to lower consumers' energy bills."

"HOME Magazine, as the ultimate resource guide to the best building products for home buyers and remodelers, is happy to honor Johns Manville Gorilla Wrap for its innovation and high performance," said HOME Magazine Vice President and Editor-in-Chief Donna Sapolin.

Johns Manville designed Gorilla Wrap to meet builder and home buyer needs by recognizing the performance shortcomings of ordinary housewraps. Unlike most housewraps on the market, Gorilla Wrap is non-perforated, reducing the potential for bulk water penetration and allowing trapped moisture to escape, reducing concerns about mold and mildew growth. In addition, the non-perforated material keeps wood sheathing drier, reducing the potential for rot and degradation within the wall cavity, both during construction and many years later.

An EPA-approved antimicrobial agent protects Gorilla Wrap from potential damage by mold and mildew. No VOCs are released in the manufacture or use of the product. Gorilla Wrap improves energy efficiency by providing a highly effective air and water barrier, and a water-based ink is used to apply the product logos and brands on the housewrap material. The product can be recycled if removed from a building after initial application.

"Gorilla Wrap is another example of Johns Manville's commitment to the continuous improvement of our building products offerings and the enhanced performance of all aspects of the building envelope," said Kambs.

All JM products undergo rigorous testing at the Johns Manville Technical Center to ensure products perform properly and are safe for home installation. Third-party testing of Gorilla Wrap's physical properties was also completed by RADCO, a nationally recognized testing laboratory and a listing and quality control inspection agency. Gorilla Wrap meets ICC code requirements for Water Resistive Barriers and Air Barriers. For more information about Johns Manville Gorilla Wrap, go to www.gorillawrap.com or call 800-654-3103.
