I am finishing my basement, and have a question on insulation. The home builders installed a fiberglass "blanket" drape over the entire cement foundation walls of the basement. This drape has a plastic layer that faces the living area, I am assuming acting as a vapor barrier.
When the basement walls were framed out, the drape was left in place and the walls were spaced out from the foundation walls. My question is this. If I want to add additional insulation between the wall framing, to up the basement wall R-value, what do I need to do, as it pertains to the vapor barrier?
Removing the plastic from the wall drape isn't really an option, because that is how it is attached to the wall. Can I simply add new fiberglass insulation between the studs, then add another vapor barrier to finished wall? Or is it a no-no to have a vapor barrier sandwich like I would then have?
