One wall of my shop is poured concrete which needs to be insulated. With the cold weather recently in this area and temps down to 5-15°F region, the walls are very cold and it is difficult to heat (and expensive). I have searched several places and found the most recommended is the following -
1-1/2" foam insulation board (pink) glued to the concrete and the joints taped
Stud the wall out and fill with R-13 fiberglass insulation and with kraft paper toward the warm side of the wall
Drywall over the studs ( I may just use pegboard.
I have read several different thoughts on a vapor barrier. I do not have a water problem on this wall and so will not use a vapor barrier except for what the kraft paper side of the insulation provides.
I hate losing 6" of my shop with the insulating and wall but this provides the best insulation.
What have other people done for basement walls?
