Moisture Damage Protection for Exterior Wall Systems

DrainVent Rainscreen

DuPont Safety & Construction, a business unit of DowDuPont Specialty Products Division, 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.
