I am going to start finishing my basement in a couple weeks with the framing. My question is regarding the proper installation of vapor barrier. I was thinking of stapling the vapor barrier to the studs so it creates a barrier between the studs and concrete wall. Others have told me that putting it on the interior is better....what are your thoughts or suggestions? How have others done this? Installing it on the interior would seal the insulation between the concrete and vapor barrier...which sounds like a recipe for disaster to me. Also how would you route piping and conduit?
Traditionally, the vapor barrier would be attached to the interior studs, below the sheetrock. Any invasions of this barrier would be sealed on a case by case basis with a plastic type pocket
That being said. I erected my steel walls 2" away from the foundation and wrapped a vapor barrier behind the studs, under the bottom plate and up the front of the studs( under the sheetrock). I didn't want moisture from the foundation driving into the fiberglass from behind.
I live on Long Island, NY which is also a cold zone and have had no moisture issues since I've done this in 1996. I know this because I left 6 observational openings so I could monitor each exterior wall, top and bottom.
