Floor over slab insulation?
I live in Pittsburgh, PA. I’m turning an existing porch into a dinning room. There is an existing 6″ slab with 1 1/2″ thick pavers over it. The pavers are cemented to the slab and grouted. Dirt under the slab.
The local code calls for R10 insulation 2′ in around the perimeter walls. I wanted the entire floor insulated. My contractor only did the 2′ perimeter insulation. In your opinion is this OK?
