Yeah, well, sorry about that. I was what the helling the large green lozenge and I wasn't nice about it. Here in California we've pretty much forgotten what vapor is.
How does the vapor barrier final installation go? Does the barrier eliminate vapor or just reduce it a lot? After the drywall is up, what do you do to get to the wire? Do you end up opening a single gang hole in the face of the barrier?
Vapor barrier keeps the moisture on the warm side of the wall, so it can't condense and cause problems.
