We had one room remodeled. One west wall (upstairs),one north and south wall now has outside insulation, fiberglass interior, poly sheet vapor barrier, and dry wall. Now I am wondering if we need to remove it. It is only in one bedroom, but I read your article and now I am concerned. Please give your thoughts. Thanks.

Phette,
You haven't given us enough information to answer your question.
We need to know:
1. Your location or climate zone.
2. More information on the "outside insulation." Is it rigid foam? If so, what type (XPS, EPS, or polyiso)? How thick is it?
