Made with a unique non-woven fiber structure, Tyvek® DrainWrap™ works behind claddings to channel bulk water away from the wall assembly while allowing water vapor to pass through. It also provides air resistance and structural durability during construction. A vertically-grooved surface provides added protection against water, by enhancing drainage away from the wall assembly. DuPont™ Tyvek® DrainWrap™ is a moisture barrier designed to provide enhanced drainage in areas subject to extreme, wind driven rain. It combines the exceptional air and water resistance, vapor permeability and strength of Tyvek® with a vertically grooved surface, to help channel water safely to the outside.
