DuPont Building Envelope systems are designed to help meet the growing demand for more sustainable buildings. We continue to create products and processes that pass rigorous criteria for use in buildings designed to use less energy, water and materials.
Innovative DuPont™ Tyvek® weather barriers and other DuPont Building Envelope systems products apply field tested material science to help in the sustainable design of commercial and residential buildings.
Energy consumed during building operation – from lighting to heating and cooling — accounts for the major share of energy consumption over the life of a building. Helping to create an air-and water-tight building envelope contributes to energy efficiency in three important ways:
Efficient HVAC operation and IEQ (Indoor Environmental Quality) are core features in sustainable buildings. DuPont Building Envelope systems help reduce the envelope loads and improve the HVAC efficiency by protecting against air and water infiltration. By reducing air infiltration, DuPont Building Envelope systems can help maintain comfortable temperatures and IEQ. By preventing bulk water intrusion into the walls, they also help reduce the risk of mold and mildew, and maintain IEQ.
For residential construction, weather barriers can help keep external contaminants from entering a building, which can help meet garage separation recommendations from green rating systems.
Keeping out bulk water and allowing moisture vapor to escape can help extend the life of the walls by inhibiting water damage, corrosion and mold. Dry walls can help extend the life of a structure by reducing the risk of water damage or corrosion to structural materials. This can mean fewer materials are needed for repair and replacement, over the life of the building.
