I’m converting a barn to a residence
The slab is not insulated, and there are no below-grade details beyond the posts that support the structure. My architect is resistant to insulating on top of the slab. He worries that if I don’t leech heat into the soil…
The slab is 64′ x 46′, and 4″ thick. The central section was tapered toward center drains, so we have some leveling to do. We are in zone 5, I believe, and temperatures have recently dropped to -18F, though that is unusually cold. My concerns are comfort as well as avoiding condensation that might degrade floor coverings and encourage mold growth.
