Tue, 4 Dec 2012 04:04:56 EST

Along the coast where wind-blown rain is a regular weather feature, it's no surprise to builders that the exterior of a home must be carefully detailed to manage water. Properly installed housewrap and flashing are the key elements of an effective water-resistive barrier. But rainwater is not the only moisture source, explains building-science consultant Steve Easley. The air itself, particularly the humid air associated with coastal regions, carries a significant moisture load as well. This means that sealing up air leaks is a vital step to managing moisture.
