DuPont, Yellowstone National Park Partner to Address Long-Term Sustainability of Park Structures

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™ Tyvek® Weather Barrier Systems are being used by Yellowstone National Park to help
reduce the energy load required to heat and cool buildings and to protect structures from air and
water penetration, while still allowing moisture to escape.

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.

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.
