Here in Northern Virginia, every sheetrock hanger I know (or have used on a job) glues the board. Whether they are using nails or screws, they wouldn’t think of hanging without glue. Now I’m seeing more and more articles about using unfaced insulation with a poly vapor barrier over the framing. I understand the theory behind this. It is rarely, if ever, done around here. Is this something that’s unique to New England or more severe climates further north? And since glueing the drywall to a sheet of poly would be useless, do the hangers use 3 times as many fasteners per sheet? Can you still get as good a job?

My experience with drywall glued to the studs comes from the demolition and remodeling side. I hate it. Tearing off glued drywall is difficult. Then you have to scrape/cut the glue off the studs before putting on new drywall. I think glue is used so fewer screws or nails can be used. I use sufficient screws when hanging drywall and no glue ever. The screws don't pop and the drywall doesn't fall off the wall.

Scott:
Do you also see sheetrock glued over cellulose insulation without any vapor barrier? And when it is glued, have you seen sheets glued to the wall and only use two screws in the middle of a 54"x96" sheet?( In addition to the screws around the edges)I see both in the Fredericksburg area.
