All right, here's one for the burly men (and burly women) in the crowd.
This summer, my wife and I bought an old house (1932). We love it, and have been fixing it up bit by bit. One real problem is that the house is not well-insulated... our energy bills are higher than I'd expected. I'm attacking this problem one piece at a time, and next up is the basement.
It's always freezing down there, and I'd like to see what I can do about insulating it. A friend (but I can't remember who) told me there's a new insulation that you right up against cinder block. He/she said it looks like drywall, and you can paint it, but it's just as good as roll-out fiberglass. Unfortunately, I can't for the life of me remember what this stuff was. Anybody got any ideas?
