I'm going to renovate my basement, currently there is paneling on the walls, with wood studs and fiberglass insulation. It's pretty old and according to the previous homeowner and inspector, there is no moisture down there which is good. I haven't started taking down the paneling yet, but should the insulation be ok if there's no moisture? What should I look for, how do I know if I should change the insulation, and if I do, should I put some sort of moisture barrier to prevent mold? Could I add a moisture barrier and keep the same insulation? Also, is it a good idea to change to metal studs? Thanks, and sorry for so many questions.
