I am building a new home in zone 4, Shelbyville, Kentucky. This is my house plan:
I am using the tremco basement waterproofing system and using a board on the outside which we carry the water away down to the footer and insulate to a value of R5. The basement slab will be insulated with foam board under the concrete floor. I am finishing the downstairs with drywall and wall studs. Since there is R5 insulation on the outside of the basement wall, should I insulate inside the basement as well? If so, what insulation do you recommend? I have seen foam board recommended to be placed against the wall, then 2x4 frames be put up over that. Will the outside board keep condensate off the wall in zone 4? Foam board inside or no foam board?

Can R-10 XPS foam against concrete and R-15 mineral wool batts between framing be combined in a basement?
