I recently purchased a house with a poured foundation that has an unfinished basement. I would like to completely finish it but I'm confused on which way I should insulate it. Should I stud it up with an air space (up to 1") between the studs and the foundation and insulation with vapor barrier or should I thermal strap with foam. Which will give the me the best comfort in the end. I've been thinking also of thermal strapping the floor, is this wise or just a waste of money.
