Looking to see best way to do this. I was going to use 1-1/2 rigid foam tight to concrete walls then frame 2x4 walls tight to foam with batt insulation. I was thinking however this might be overkill with the insulation. I also thought of using just 2 layers of strapping in a crossing fashion tight to the foam and fastened into to concrete and avoid using studs all together. It will save money on insulation as the foam has the required r value as is. What are you thoughts.
