Insulation missing in space between first floor ceiling and second floor subfloor
We are adding a second floor addition to our one story house. We’re living in it while it’s happening so most of the ceiling is staying intact as they add new floor system above. The contractor laid subfloor without insulating the exterior walls (bands) between the first floor ceiling and second floor subfloor. We can cut back the subfloor in most areas but there’s a few places where it’s impossible. Is this problematic from a condensation point of view? Will the conditioned air in that space meet the exterior wall and create condensation and rot the exterior wall sheathing in those areas?
