Also, what year is your house? Mine is 1942 and I'm just curious. Since I can see inside my walls, I can see the old insulation. We're getting it fixed before winter, so we won't know how cold it can get in here. At least not in the top part. There will still be a few walls without new insulation, but they're not in rooms we use all the time.

And hey, you never answered my questions! ;p
