Concrete slab details
My architect has drawn the attached detail for a house in Madison County NC just above Asheville, so in climate zone 4A-5A. We have chosen AAC walls as we are somewhat isolated and far away from any fire departments. We will have an outdoor wood boiler with radiant heating in the concrete slab. My initial questions are: Since the radiant heating pipes and all of our plumbing is in the slab, would a 6″ slab offer any benefits over a 4″ slab? With radiant heating in the slab, how much insulation should we have under the slab?
