08, Apr 2019


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.
