DuPont™ Tyvek® and other sustainable building products from DuPont have received the Green Approved Product Seal for National Green Building Certification.

Sustainable building products can contribute to reducing use of fossil fuels, a benefit for society as a whole. But the DuPont products listed above can also benefit home owners, by helping to protect against bulk water intrusion and air infiltration.
This can contribute to improved energy efficiency, and prevent the formation of mold in the wall assembly. In fact, DuPont data shows that the use of Tyvek® Building Envelope systems products can help reduce annual energy costs up to 20 percent over a house without an air and water barrier.
