DuPont™ Tyvek® DrainWrap™
Grooved Air and Water-Resistive and Air Barrier (WRB) Engineered to Enhance Drainage
<br><b>DuPont™ Tyvek® DrainWrap™</b> offers excellent drainage and durability for residential construction. Vertical grooves on the surface of <b>Tyvek® DrainWrap™</b> make it a superior water-resistive barrier (WRB), engineered to channel bulk water away from the wall systems and drain safely to the outside. <br><br> Combined with the superior air and water resistance, vapor permeability and strength of the Tyvek® Brand,<b> Tyvek® DrainWrap™</b> provides enhanced drainage behind claddings such as primed wood (all six sides), fiber cement siding, and foam board applied over flat surfaces.

Features & Benefits
High Performance Durability
- Outperforms other textured water-resistive barriers in tests involving bulk water application.
- Provides superior sustained performance compared to Grade D building paper and #15 felt.
Temperature and UV Resistance
- Withstands up to four months (120 days) of UV exposure.
- Maximum in-service temperature of 180° F.
Air and Water Barrier Performance
- Helps hold out bulk water, while allowing water vapor to pass through it, promoting drying in the wall system, which can help prevent mold and water damage.
- Unique non-woven structure helps prevent air movement through walls, contributing to a more energy efficient building.
- Type I air barrier per ASTM E1677.
- Offers > 98% drainage efficiency when tested in accordance with ASTM 2273.
- Meets ASTM E2556, Type II standards for vapor permeable flexible sheet water-resistive barriers.
- Pliable, wraps around corners with ease.
- Lightweight, easy to handle, and faster to install than the average house wrap.
- Flexible, easily interfaces at joints and over architectural elements.
- Minimizes seams and helps reduce labor costs.
- Maintains constant drainage rate, even after repeated wetting and drying cycles.

FAQ
What’s the difference between DuPont™ Tyvek® CommercialWrap® D and DuPont™ Tyvek® DrainWrap™? Each of the WRBs help with drainage, with both having a 98% or greater drainage efficiency per ASTM E2273. The major difference between the two WRBs is the UV exposure. Tyvek® CommercialWrap® D can be left exposed for 9 months while Tyvek® DrainWrap™ has a 4-month UV exposure. These UV exposure limits were designed for the products applications. CommercialWrap® D is typically used on commercial projects while DrainWrap™ is used on residential projects. For additional information regarding application and use refer to the installation guidelines for the applicable project type. Can DuPont™ Tyvek® DrainWrap™ be used under brick? Yes. It is perfectly acceptable to use DuPont™ Tyvek®DrainWrap™ under brick.It is also acceptable to use Tyvek® HomeWrap® and Tyvek® CommercialWrap® in this application. When using Tyvek® WRBs under brick, it is important to follow the brick manufacturer’s guidelines regarding the use of an air space between the brick veneer and sheathing. Typically, this space is 1-2 inches, and will act as a drainage plane if incidental moisture penetrates the brick, in addition to ventilating behind the cladding, which aids in drying of the wall assembly.
