Interesting.7', which was what is what's called for in my location.
No frost wall, just thickened edge slab.
Did 2ft on my old place, seemed like it was a waste of foam.
This place doesn't have it and the snow melts no different near the building.
If anything, this one is better, can stand barefoot near the walls inside and the slab is still warm.
Old place would be ice cold.
