Currently doing a reno on our basement. After roughing everything out, I have insulated the outside walls with R13 (2x4). The house has never had insulation in the basement. Should I insulate the ceiling as well? The ceiling is 2x6 and I think R19/R22 should do. Is this practical/good benefit or am I just wasting my time/money. The house is in New England, basement is dry, standard poured cement style.
The answer to this question will help: How should I insulate my basement?
Short answer: You don't need to insulate the ceiling, but you can optionally do it if you want some sound blocking.
