Monolithic slab in a cold climate
I've been talking to an excavator who says that he has done quite a few monolithic slabs up here in Vermont, including one for his own home. I'm wondering if anyone else has used a monolithic slab in a cold climate and if so, how did they do it? I'm thinking that 4" of foam insulation under the slab and another 4" around the slab would work, but I wonder how far out it should go. I also wonder about what kind of vertical insulation to use around the slab perimeter. Any advice?

Is it OK to step the slab thickness over the footings to accommodate insulation between the slab and the footings?
