Basement has been waterproofed and has I guess you could call it a vapor barrier installed so that any water that would get through would get channelled down into the sub drain the contractors put in. I have the furring strips attached and was starting to get things in order to insulate the walls and I started questioning myself (I guess I suffer from OCD because most people probiably would just run with it) what type of insulation should I use? Should I use the non foil lined Styrofoam or the foil backed stuff? I thought for a moment and considered it a possibility that I was creating two vapor barriers and that could lead to problems being the wood furring strip would take the brunt of the moisture if I were to use foil backed stuff. Am I correct in my concern? If so just regular 1 1/2" styrofoam insulation would be the ticket yes or does it not matter? I know that fiberglass is a definate no-no due to mold concerns etc. Pictures attached so you can get an idea if my description isn't good enough. Thanks guys.
