DuPont™ Tyvek® DrainWrap™ CA

Grooved Air and Water Barrier Engineered to Enhance Drainage

<br><b>DuPont™ Tyvek® DrainWrap™ CA</b> moisture barrier offers excellent drainage and durability for homes. Vertical groves on the surface of <b>Tyvek® DrainWrap™ CA</b> make it a superior moisture barrier, engineered to channel bulk water away from 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™ CA</b> helps provide enhanced drainage behind claddings such as primed wood (all six sides), fiber cement siding, and foam board applied over flat substrates.
 
 
 
 
 
 

Features & Benefits 

 
 
 

default-features-benifits.png
Ease of Installation
  • 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
default-features-benifits.png
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.

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.
