DuPont™ Tyvek® DrainWrap™
Grooved Air and Water-Resistive and Air Barrier (WRB) Engineered to Enhance Drainage
DuPont™ Tyvek® DrainWrap™
Grooved Air and Water-Resistive and Air Barrier (WRB) Engineered to Enhance Drainage
<br><b>DuPont™ Tyvek® DrainWrap™</b> offers excellent drainage and durability for residential construction. Vertical grooves on the surface of <b>Tyvek® DrainWrap™</b> make it a superior water-resistive barrier (WRB), engineered to channel bulk water away from the wall systems and drain safely to the outside.
<br><br>
Combined with the superior air and water resistance, vapor permeability and strength of the Tyvek® Brand,<b> Tyvek® DrainWrap™</b> provides enhanced drainage behind claddings such as primed wood (all six sides), fiber cement siding, and foam board applied over flat surfaces.
