We built a "pretty good house" in Jefferson NH this year and are getting condensation on the interior of the windows.
We have 3 layers of 2.5" XPS with staggered and sealed seams on the walls and 4 layers on the roof. So 7.5" and 10" respectively. The interior stud cavities have been left open and empty. The windows are set as "outies" and the doors as "innies" and space between the studs/plywood boxes and the doors/windows were filled with cans of window and door spray foam. The house is heated by two mini splits and has been performing very well to date. It is a vacation home and when we come back after a week plus away there is condensation at the bottom of the glass of the window. We have yet to install the HRV, it is going in next week, but we are concerned that it will not remedy this issue. Do you think it will remedy this issue, and if not is there another tact we should consider?
