I am finishing my basement and have a room that will have soffits covering utilities around the entire perimeter of the room. Two sides of the room will be against a poured foundation wall which I plan to apply a plastic moisture barrier over the studs and insulation. Do I wrap up the wall and then out and up over the soffits as well? This is the only way I can think of doing it and keeping the integrity of the seal. I am in Atlanta area so pretty mild climate.
