Do we need vapor barrier if installing fiberglass insul in basement (MD)? I have read dozens of internet articles & so many conflicting opinions. Basement is below grade, painted with Drylock & metal studs about 1/4-1/2 inch from foundation. I don't want to spent $$$$ for spray foam, which seems best. Can I simply put kraft paper batt (paper facing interior) & drywall over?.....
You should not install a vapor barrier on the inside of a basement wall since the wall needs to dry to the interior. Spray foam is an excellent method as long as it is gas permeable. Unfaced fiberglass insulation is fine too. I think you would be better off with wood studs since they do not conduct heat the way metal framing would. The idea is to try and prevent condensation on the metal on the cold side of the wall.
