I have an off grade house that was built in 1952. I think it still has only the originaly insulation in the attic. Which is probably only about 2 inches and has two large gabels on each end. I know for sure I need more insulation in the attic, but my question is should I reduce the size of the gabels. Also it is cost effective to insulate the underside of the house? The floor is always very cold.
Thanks for any help. I appreciate it very much.
