    swooley,

    Have you got a section through that area? It’s hard to understand what’s going on. I ask because how important that thermal bypass is depends on where the rest of the insulation is.

      Malcolm,

      You can see the side of the house here from an earlier pic. Rigid is just at the top of the gravel and goes down below frost line (24”).

        swooley,

        Sorry, I should have been more specific: What are we seeing on the left hand side? Is there a step in the stem-wall and we are seeing insulation on it, or is that a framed wall? What connects the two layers of rigid insulation we see to stop heat bypassing them on the brick ledge? A very rough sketch of the foundation there would be really useful.
