DuPont Tyvek DrainWrap offers excellent drainage and durability for residential construction. Vertical grooves on the surface of Tyvek DrainWrap make it a superior water-resistive barrier (WRB), engineered to channel bulk water away from the wall systems and drain safely to the outside. Combined with the superior air and water resistance, vapor permeability and strength of the Tyvek Brand, Tyvek DrainWrap provides enhanced drainage behind claddings such as primed wood (all six sides), fiber cement siding, and foam board applied over flat surfaces.
High Performance Durability: Outperforms other textured water-resistive barriers in tests involving bulk water application.
Temperature and UV Resistance: Withstands up to four months (120 days) of UV exposure.
Air and Water Barrier Performance: Helps hold out bulk water, while allowing water vapor to pass through it, promoting drying in the wall system, which can help prevent mold and water damage
