Windows and doors in double-stud walls

摘要

As noted in the previous "Energy-Smart Details," double-stud walls have high R-values and are straightforward to frame. If you look either at the interior frame or the exterior frame of a double-stud wall, it looks like a single-stud wall. The tricky part of double-stud wall construction is the gap between the inner and outer walls that window and door openings need to bridge. This requires attention to the moisture- and air-control layers, the operation of the window or door, and the finish details.
