Why is there frost/ice formed on inside of drywall!
Just moved into a new house a few months ago... (4 level split with 3rd level on a concrete slab). On the 3rd level in the corner of our family room there was ice on the drywall (very cold out -45 with wind chill). Was wondering if possibly vapour barrier was not installed correctly because I know for a fact there is insulation behind the wall? Another person mentioned because we had several large blankets stuffed in this corner that is why the ice formed between the wall and the blankets... any truth to this?
