Basement Insulation R-Value
I'm going to be insulating and framing the walls of our poured basement. We live in Michigan's Upper Peninsula on top of a well-drained bluff so our basement is very dry and the climate is very cold in the winter.
Any recommendations for R-value? I've read that an R value of 25 would be recommended for our region.
The plan is to use 2" foam board against the concrete, then frame against that and roll in insulation between the studs.
Any recommendations or advice for our project would be appreciated. Thank you.
