The DuPont Tyvek DrainVent Rainscreen, DuPont Safety & Construction’s newest addition to its Tyvek envelope and exterior product line, is designed to create a 6 mm/0.25-inch space behind a home’s exterior cladding for water drainage and air movement. This not only allows for drying behind cladding, but protects against moisture damage to exterior walls, including rot, cracking, and peeling.
The Tyvek DrainVent may be installed behind stucco, stone veneer, brick, wood, fiber cement and metal panel cladding. It replaces the intervening layer required for stucco and stone cladding, and prevents mortar or stucco infiltration with a layer of filter fabric.
“We are bringing new solutions to help our customers build high-performance walls and provide peace of mind for homebuyers desiring the most popular claddings and designs. DuPont Tyvek DrainVent helps walls dry by simply letting water drain, and air to circulate behind the cladding, to help prevent long-term damage to the structure,” says Alan Hubbell, Residential Market Manager, Performance Building Solutions, DuPont Safety & Construction. “The new offering is an important addition to our DuPont Tyvek weatherization portfolio and customers can rest assured it will offer the performance, reliability and durability expected from a leader like DuPont.”
The Tyvek DrainVent material uses a honeycomb-textured design to provide protection against exterior moisture damage. The roll is designed to be easy to cut, roll tight against corners, and lay flat. The material carries both a high perm rating for breathability and a Class A fire rating as per ASTM E84.
