How much air gap before a wall is not considered a leaf?

Is there a general rule of thumb that dictates how much of an air gap must exist between a stud wall (or a double stud wall) and an outer wall before the outer wall is not considered a leaf of the design? I apologize if this has been covered, but my search didn't turn up a result. Thank you in advance! -Bryan

The short answer is no. The goos answer is that as the gap becomes greater, the gap is no longer "wasted space" but becomes usable floor area. I am certain you have slept in rooms with quadruple leaf partitions and noticed no sound from the room on the other side. Or at least coming through the partition,a s it would be through the openings. Are you in suspense after reading my last sentence? Think of hotel rooms across the hallway from each other. :shot: Andre

dunno, i'm sure i've heard things from across the hall i don't want to think about... :oops: then again, maybe that was due to lack of good seals on the doors :wink:

Agreed. Strategically located marine life is critical for best hotel room satisfaction. :love: Andre
