In a sealed CS, they insulate the WALLS. It is not a conditioned space and they remove the floor insulation.
I am not impressed with only 2 inches on the walls and that there has to be a gap from the insulation to the rim joist for termite inspection, but it is still the way to go. A sealed CS is like a basement. We don't have that gap in basements. I think this is due to insufficient treatments. It is a big step forward, but I don't think it is still the right way to build a house. My last house was a slab, and it was not the right answer either. ( 1963 era, so no insulation)
