Basement framing and insulation question
I'm no expert but sharing what I am doing. Using rigid foam r13 along studs exterior wall which is concrete. I used drylok extreme paint to water proof the porous concrete in my basement. It typically brings moisture in slowly but this should deter it. The 2" foam will act as my moisture and vapor barrier as well. The basement is typically controlled and should maintain fair temperatures. I am using drywall right on top with a 1.5" space between foam and drywall for breathing.
