Our lowes has this in 1.5" and 2" insulation... 2" is R-10... was just a little concerned about where it's only 1" thick where the furring strips would go... but if that still is a problem, might as well cough up for the XPS 2" and frame it out
btw.. what kind of adhesive is best for this to the cinder blocks?
