I have a pole barn that I'm turning into a small apartment. The roof consists of simply a metal roof, with a blanket of insulation next to the metal underside, and a white vapor barrier on the bottom side of the insulation, then the purlins.
My question is: Would putting up R-21 insulation next to the white vapor barrier, then sheetrocking the ceiling add to any potential condensation problems? Right now, I have a little condenstation but it stays between the vapor barrier and metal roof. It gets the current insulation just a little damp. You can see a picture of the interior ceiling by using the link. Thanks.
