HELP insulation question for my bathroom walls
I am remodeling my bathroom it is a very old drafty house the contractor has recommended to use fiberglass insulation with 6 mil thick plastic over that and double sheet rock the out side wall.
My question; Is it okay to use plastic over the walls and ceiling? I always heard the house has to breath. The contractor tells me the exhaust fan will take care of the moisture. Help we are getting close to insulation time!
