Am I right in thinking that thermal bridging where a 100mm polished concrete floor meets a door/glazed area is inevitable? We have cavity walls - we were going to lower the inner block and extend the insulation through to the outer block. I understand that normally perimeter insulation would be used, and then the final floor covering would cover that. However, in this case, because the final floor covering is 100mm, there's no room for perimeter insulation (unless it was to remain visible)?
Secondly, if this is the case, how significant will it be? We will have UFH so will definitely lost a bit of heat here. But will it be a major cost-issue? With thermal bridging, as long as the heat loss isn't insane, I am mainly concerned about condensation/mould. But I figure if the UFH is always on low in winter, this will keep the area warm.
