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?
