I have an old house. In the basement I want to take down exising plywood walls and replace with proper insulation and wall board. It seems it is recommended to insulate the rim joist area as well as the walls but I've noticed that the floor joists are embedded within the concrete(house built in late 1920s). Is it wise to insulate the rim joist area if the joists are embedded in the conrete?
Thanks for any advice.
