The Best Weather Resistant Barrier Options For Homes In The Pacific Northwest
DuPont Tyvek Drainwrap
Drainwrap helps provide enhanced drainage behind claddings such as primed wood (all six sides), fiber cement siding, and foam board applied over flat substrates. Vertical grooves on the surface of Tyvek® DrainWrap™ make it a superior moisture barrier, engineered to channel bulk water away from wall systems and drain safely to the outside. Its unique structure 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. This also helps prevent air movement through the walls, contributing to a more energy efficient home.
Benjamin Obdyke Hydro Gap
This product effectively eliminates excess moisture which protects against the damaging effects of mold and rot. Hydro Gap sheds bulk water away from the structure, up to 100x more than standard house wraps on the market.
HardieWrap® Weather Barrier
HardieWrap is a high performance weather barrier made by James Hardie, the top producer of siding in the United States. HardieWrap weather barrier offers a balance of water resistance and breathability. This allows moisture from inside your home to escape which, in turn, keeps the area within the wall dry.
Moisture and water infiltration is a significant problem in the Pacific Northwest, especially in Portland. As a result Oregon has adopted a new code to help eliminate moisture infiltration. A weather resistant barrier (WRB) is your home’s best defense against the elements.

New Oregon Siding Repair Code
The Oregon siding repair code was adopted on January 1st, 2010. The new code requires that there is at least 1/8″ gap between the siding and the weather resistant barrier (rain-screen). It’s important to consider Oregon’s new siding regulation when completing a siding repair or dry rot repair project. There are a few exceptions to this rule.
Space is not required where:
- Window sills are equipped with pan flashing.
- An enhanced drainage system is installed that meets 75% drainage efficiency.
- It is matching the existing exterior finish as in additions, alterations, or repairs.

Though you may want to familiarize yourself with this document, it is not your job to know these specifications, it is ultimately the responsibility of the contractor you hire to work on your home.
