I'm mapping out my basement remodel. It was finished in the 1960s with yellow psychadelic floor tile and paneling installed with furring strips
. I plan on fully studding the walls, mainly for plumbing, running HVAC ducts down to the floors and possibly insulation.
BUT- I discovered the exterior walls of my house do not have any insulation
My energy bills aren't terrible, even with the original 1955 windows (though they do have storm windows). My bills have been around $100 a month for wintertime electric and gas. I'm wondering if there is any point in insulating the basement walls and rim joist in this situation.
My thought for insulating is, since the basement is naturally colder, it will help keep heat in the basement before it flows up to the upper level.
My thought against is- it may not be worth the expense or effort, since the upper levels have no insulation in the walls. Also, I should note parts of my house the exterior brick veneer walls are below grade. It's been like that for 50+ years and I don't see any evidence of mortar failure. One theory I have is since there's no insulation, heat from the basement comes through and prevents the damaging effects of the brick soaking up water then freezing. If I insulate the wall, then the brick may freeze. This is only my thought and I may be totally off, so that's why I thought I'd ask here
