basement floor & wall insulation & vapor barrier
We want to finish our basement space which is partially above ground and partially underground. The part that is underground has poured concrete walls and the rest is framed. We are trying to determine the best way to insulate and waterproof. I have seen you put polystyrene insulating board on the basement walls for vapor barrier and insulation, but what would be the best way to waterproof and insulate the basement concrete floor? Or Is this necessary?
