Tyvek DrainVent Rainscreen

Dupont Tyvek DrainVent Rainscreen is made using drainage mesh that is laminated to a filter-fabric backing. Each roll contains a 3" flap of fabric to provide an overlap of the lower courses or to act as an insect screen. DuPont Tyvek DrainVent Rainscreen blocks mortar and stucco infiltration, while also creating a 6 mm gap that prevents rot, cracking, and peeling by promoting movement and ventilation of moisture in the wall cavity.
