DuPont Products Help Protect and Preserve Buildings

Wilmington, Del., January 17, 2008 - When construction on the Old Faithful Visitor Education Center at Yellowstone National Park is complete, it will have been outfitted with DuPont™ Tyvek® Weather Barrier Systems. The DuPont products used in the building, along with others throughout the park, are helping to reduce Yellowstone’s overall energy consumption, as well as prepare it for increased visitation while mitigating risk to its natural resources.

“DuPont is proud to help contribute to the preservation of one of the nation’s most beautiful natural treasures,” said Thomas F. Schuler, vice president and general manager – DuPont Building Innovations. “This partnership is consistent with our commitment to help create sustainable solutions for buildings everywhere.”

Through the nonprofit Yellowstone Park Foundation, DuPont is donating its full portfolio of moisture management and weatherization products to help Yellowstone reach its goal of becoming the most sustainable national park in the United States. Yellowstone National Park is embarking on a series of new construction and remodeling projects throughout the park including the Old Faithful Visitor Education Center, the Yellowstone Justice Center and a new Canyon Ranger Station. DuPont™ Tyvek® Weather Barrier Systems will help reduce the energy load required to heat and cool the buildings and protect structures from air and water penetration, while still allowing moisture to escape.

"We are so pleased to begin this partnership with DuPont and expect it to flourish for years to come,” said Paul Zambernardi, executive director, Yellowstone Park Foundation. “DuPont™ Tyvek® is perfect for the extreme weather in Yellowstone and will assist the Park greatly in its ongoing efforts to improve its energy efficiency."

DuPont™ Tyvek® Weather Barrier Systems provide the industry’s best combination of air, water and moisture management properties. Based on 30 years of research and development measuring wall system dynamics and the attributes of secondary weather barrier systems, DuPont research indicates that protecting wall systems from water infiltration helps to prevent the growth of mold.

Additional Tyvek® applications for construction include Tyvek® AtticWrap™, the first breathable roofing membrane to create an airtight attic, and Tyvek® ThermaWrap™, which helps provide reduced energy costs and increased comfort by improving the reflection of radiant energy in wall systems. DuPont also manufactures Tyvek® Weatherization Systems, including: DuPont™ Tyvek® CommercialWrap®; DuPont™ Tyvek® DrainWrap™; DuPont™ Flashing Systems – DuPont™ FlexWrap™, DuPont™ StraightFlash™ and DuPont™ Thru-Wall Flashing; DuPont™ Tyvek® Tape and DuPont™ Wrap Caps.

Additional offerings from DuPont Building Innovations include DuPont™ Corian® solid surfaces, DuPont™ Zodiaq® quartz surfaces and Granite Certified by DuPont™; the DuPont™ StormRoom™ with Kevlar®; DuPont™ SentryGlas®, and; DuPont™ RoofLiner with Elvaloy®.

DuPont – one of the first companies to publicly establish environmental goals 18 years ago – has broadened its sustainability commitments beyond internal footprint reduction to include market-driven targets for both revenue and research and development investment. The goals are tied directly to business growth, specifically to the development of safer and environmentally improved new products for key global markets.

DuPont is a science-based products and services company. Founded in 1802, DuPont puts science to work by creating sustainable solutions essential to a better, safer, healthier life for people everywhere.
