Tyvek Drainwrap

  • Resists Air Penetration

  • Resists Water Penetration

  • Allows Moisture to Escape

During exterior wall sheathing with oriented strand board we wrap our houses with Tyvek drainwrap rather than standard house wrap. Standard house wrap allows water to rest on the house wrap and slowly drains away. Tyvek drainwrap has vertical groves which gathers water and quickly drains the water to the outside of the house.
