Stone foundation - dirt floor basement... insulation?
Has anyone insulated a stone foundation, dirt floor basement? A friend of mine (with a new house) suggested the spray foam insulation. I wonder if anyone has done it in an OLD house. It is supposed to be insulating AND protect from moisture.
I know the cost is more then anything else... but the other options is leaving the basement uninsulated and I wonder what that will do to the heating costs over time!
