DuPont™ Tyvek® DrainWrap™

Engineered Residential Weather Barrier with Vertical Grooves to Channel Water

DuPont™ Tyvek® DrainWrap™ is an engineered weather barrier that builds on the weather-resistive properties of DuPont™ Tyvek®. It has vertical grooves on the surface to help channel bulk water while allowing water vapor to pass through the moisture barrier, which helps to promote drying in wall systems. DuPont™ Tyvek® DrainWrap™ is the product choice when enhanced drainage is desired behind claddings such as primed wood, fiber cement siding and foam board applied over flat substrates.

How It Works:

DuPont™ Tyvek® DrainWrap™ can help enhance drainage behind claddings including:

  • primed wood (all six sides)
  • fiber cement siding
  • foam board applied over flat substrates

DuPont™ Tyvek® DrainWrap™ is a weather barrier engineered with vertical grooves to promote drainage in wall systems by helping channel water safely to the outside.

The breathable structure allows water vapor to pass through the bulk water moisture barrier to promote drying in wall systems which can help in the prevention of mold and mildew growth.
The unique non-woven fiber structure of DuPont Tyvek® DrainWrap helps stop air movement through the walls providing a more energy efficient home.
