Good morning all. Looking for some input on insulating my bathroom wall next to my tub. 2x4's that will be covered with cement board and tile. Is it better, from a mold/moisture standpoint to use 3 1/2" of styrofoam or 3 1/2" fiberglas w/ plastic sheeting? and should the fiberglas have paper face? Thanks for any input.
