Moisture Management in Window Rough Openings
The phrase "leaky, drafty windows" is common in the construction industry and, unfortunately, it seems too often true. However, the perception may not be the reality. There may be leaks and drafts in close proximity to the window, but the window units themselves may not have anything to do with the problem. In many cases it is the wall system that the window unit is installed in that may be the actual source of the leaks and drafts. We need to focus our attention on the rough opening to conquer some of the air and moisture problems blamed on windows.
