How should I insulate my basement walls?
I live in northwestern South Carolina. I am finishing a basement and am planning to coat the block walls with a good damp-proofing product and then glue 1-2″ of rigid foam insulation on top of that. I plan to leave a small airspace between the rigid foam and my stud wall, which will be finished with sheetrock The ceiling will not be insulated. I have two questions:
1. Is this a good overall plan?
2. Should I still insulate the stud wall with fiberglass batt insulation?
