HELP - Lost thermal break at the slab meeting code
We are building a house in upstate NY on a floating insulated slab using ICF's on top of footers. We presented the attached original plan to the town and the building inspector came back with a requirement that we put 12 inches of concrete under our double wall with no part of the wall bearing on foam (see revised wall section). He was able to cite a section of the code that says a foundation wall must have a minimum width equal to the wall size (with two exceptions that don't apply to us). This is one argument that we will not win.
Given that the forms are ready to pour, should I be concerned about the lack of a thermal break at the foundation. My builder has said he can put in a 1/2 of polyiso. Will that be sufficient? If not, does anyone have a quick fix to address this issue. We are already behind schedule.
