Basement with Existing Stud Walls - Insulation Options
Been reading all about the recommendations for basement insulation, and feeling a bit like we need to tear apart our basement and start over! But there has to be another option, and I'm hoping someone here can shed some light on this for me.
We have Dry-lok-ed block walls, and existing stud walls (with 1/2" gap between stud walls and block walls). We're in central Illinois, so even if we could get 1/2" foam insulation in between the stud walls and the block that's not really enough thickness in our climate.
What other safe options are there?
