DuPont Safety & Construction, a business unit of DowDuPont Specialty Products Division, today announced the release of the DuPont™ Tyvek® DrainVent™ Rainscreen to provide advanced protection against moisture damage in exterior wall systems. The product is the business’ first roll good offering that creates a 6mm (0.25”) space for water drainage and air movement for drying behind cladding.

The Tyvek® DrainVent™ can be installed behind stucco, stone veneer, brick, wood, fiber cement and metal panel systems. And helps to prolong the life of exterior cladding by creating a gap that helps prevent rot, cracking and peeling problems. The product replaces the intervening layer required with stucco and stone, while the attached heavy-duty filter fabric prevents mortar and stucco infiltration.

A benefit to contractors looking for time efficient products, Tyvek® DrainVent™ is easy to cut and install, lays flat and rolls tight against corners, helping protect against poor installation and detailing errors. The heavy-duty filter fabric keeps mortar out, helps create a flat surface to allow the cladding to lay flat and has a high perm rating so it is very breathable. Thanks to its unique three-dimensional honeycomb-textured design and durability, it also provides uniform nonstructural support for the various claddings.

“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,” said 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.”

Tyvek® DrainVent™ includes a 10-year limited product warranty, and a 10-year limited product and labor warranty if installed properly with DuPont™ Tyvek® wrap and flashing products. For customers to ensure they are eligible for the warranty, it’s recommended that 

Tyvek® water-resistive barriers, like HomeWrap®, be used underneath Tyvek® DrainVent™ rainscreen. DuPont™ Tyvek® Tape and DuPont Flashing Products are suggested as well to ensure optimal building envelope performance. Using Tyvek® full system of products in this way will enable customers to take advantage of the available warranties. In addition to the warranty, the Tyvek® Specialist Network is available across the United States for additional information and customer support.

Tyvek® DrainVent™ also features a Class “A” fire rating per ASTM E84, the standard test method for surface burning characteristics of building materials.
