I know the topic of basement insulation has been reviewed numerous times, but I have not found any questions similar to this one yet. I am in the planning stages of finishing my poured-foundation-wall basement. The upper half of the walls have been covered by the builder with a blanket-type insulation (Johns Manville Basement Wall Insulation, R-11, kraft-paper) to reach down to the frostline. I intend to place wood framed walls in front of this insulation. Is this upper-wall insulation sufficient (Chicago winters) the way it is or is full-length insulation a better way to go? I could add insulation between the studs with kraft-paper batts, but I do not want to double up any vapor barriers. I could use paperless insulation between the studs, but my vapor barrier would be behind this additional insulation. Should I opt to remove the blanket insulation and insulate in the traditional manner to keep the vapor barrier against the hot wall? Please advise with some suggestions. Thanks.
