DuPont Building Envelope Solutions help make buildings more durable, comfortable, and energy-efficient. Whether it’s a skyscraper or a single-family home, the building envelope is an essential line of defense against air, water and wasted energy. DuPont Building Envelope offers solutions that meet or exceed codes, help extend building life, and help reduce fossil fuel consumption. They resist moisture and air, but are highly permeable, to reduce the risk of condensation damage, wood rot or mold growth. DuPont has been the industry leader since it invented the building wrap category more than 30 years ago. Today, we’re working with architects, builders and installers on innovative solutions for the next generation of new construction, and renovation of existing buildings.
