Hi guys im from Canada and I recently finish studying and insulating my basement. I used one and a half inch polyiso board insulation glued to the wall with adhesive and I left a half inch Gap all around the board to spray foam. In front of the wall I frame to buy for walls and insulated with Roxul insulation Batts I went to go do some electrical work today and pulled back a bath and noticed that there was a bunch of condensation and a little bit of mold in between the bat and the polyiso. Did I do something wrong here? The humidity in my basement is 45%.
Will spray foam on basement walls prevent condensation?
