Description
DELTA-VENT S is a highly vapor permeable WRB, allowing moisture within the building enclosure to escape through the membrane. Its high permeability and extreme air-tightness makes it an ideal air and water-resistive barrier membrane for energy efficient construction. DELTA-VENT S is watertight, and will help protect the building enclosure from wind-driven rain and snow while providing a drainage plane to channel water harmlessly to the outside of the building.
