Siding - Weather Resistant Barrier - SFW Construction

Weather Resistant Barriers (WRB)

Weather Resistant Barriers (WRB), a key structure to long lasting siding repairs is a moisture and air resistant envelope created with high-performance building wrap, specialized fasteners, penetration gaskets and flashings, polypropylene seam tape, and butyl flashings. There are many benefits of WRB’s.  Besides protection against water infiltration and better control of air flow WRB’s can improve your home’s energy efficiency and lower your energy costs. They also are essential in prevention of rot, mold, and mildew and help enhance your indoor air quality.

A few Water Resistant Barrier options are:

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.
