An EPD (Environmental Product Declaration) is a verified and registered document that communicates transparent and comparable information about the life-cycle environmental impact of products. The International EPD System is a global programme for environmental declarations based on ISO 14025 and EN 15804.
The EPD for Tyvek Air and Water Barrier System is Certified by Underwriters Laboratory (UL).
Use of DuPont Tyvek Air and Water Barrier Systems on Low Rise Framed Building Walls can reduce building air leakage rates and, in turn, building energy consumption required for space heating and cooling. Tyvek systems also can prevent risks associated with water intrusion and air infiltration.
