Hi All, Hope this is posted in the correct spot as it somewhat involves barriers but the dry wall is the prime concern. We moved into our new home several months ago and i'm gonna get to doing some dry walling in our basement. The basement is a walk-out. The back wall is not your typical concrete wall, but it is framed down to the footing as it seems to be what some/most builders are doing on walk outs these days. Anyway, the inside of the studded walls have insulation and a plastic vapor barrier over the inso and studs. Now while I don't really see the need (contrary to pop belief) for a vapor barrier over 8 inches of concrete, I do understand why it may be useful over the inside of a studded external wall. So during our final walk through with the home builder, the project manager pointed out that if we ever dry wall the studded wall to be sure and remove the plastic vapor barrier so the dry wall can "breathe"....HUH ? Seems like the past years all we have ever heard from building "Professionals" is that there should always be a vapor barrier installed. So my question is...do I assume that the builder is not "confused" and follow his recommendation and remove it before dry walling?...or should I leave the plastic up ?
