vapor barrier necessary?
Hi. I'm getting our 1969 basement paneling removed, adding insulation, and drywalling. My contractor says I don't need any type of vapor barrier/moisture preventative behind the drywall because there isn't really a water problem down there. That is true, but there is a dampness and mustiness. So we got a dehumidifier and problem solved. It feels great and doesn't smell musty. But I wanted to know what most people do in terms of vapor barrier? the walls behind the paneling are cinderblock painted with some sort of white paint. Do I need to insist that he add something before the insulation?
