Mitigating Water Leaks around Windows in Wood-Framed Walls

摘要

Water infiltration from outdoors into any building construction is a significant design and construction issue. The reasons are self-evident-unwanted water can cause materials to degrade, contribute to mold growth, and cause damage to people or building contents. While it is common to think of exterior walls and roofs as the primary barriers to water infiltration, the reality is that the technology to create such surfaces that can effectively resist water is readily available and fairly common. The usual problem is the openings in those surfaces, such as roof penetrations or doors and windows that become the weak points in the water tightness of walls. If window or door openings are overlooked or addressed inadequately, then the likelihood of water leaks and the related complications is high. If they are treated properly, through the appropriate use of flashing and integration with adjacent surfaces, then it is much more likely that the successful sealing and protection of walls will be achieved not only in opaque areas, but also in all of the locations where there are openings, too.
