Advanced Rainscreen Moisture Protection for Exterior Wall Systems

Easily installed rainscreen helps protect against rot and other damage in exterior walls by ventilating and moving moisture out of the wall cavity.

Tyvek® DrainVent™ Rainscreen is a three-dimensional honeycomb-textured drainage mat that provides advanced protection against moisture damage in exterior wall systems. Ideal for stucco and stone exteriors, Tyvek® DrainVent™ Rainscreen is suitable for use with a variety of other materials, including brick, wood siding, fiber cement siding, metal panel systems, cedar shake and shingles. 

Tyvek® DrainVent™ is easy to cut and rolls tight against corners, helping protect against installation and detailing errors. It offers a flat surface for cladding application, optimal compression resistance and multi-directional channels for optimal drainage and airflow. Builders who use Tyvek® DrainVent™ can enjoy the assurance that water will drain out of the wall system. 

Helps Prolong the Life of Exterior Cladding
Tyvek® DrainVent™ Rainscreen creates a gap that helps prevent rot, cracking and peeling problems by promoting moisture movement and ventilation in the wall cavity.

Ideal for Stucco and Stone
Tyvek® DrainVent™ replaces one layer of WRB required with stucco and stone. The heavy-duty filter fabric eliminates stucco and mortar infiltration.
