It is OK to use Kraft-faced batts in interior walls but it is a waste of money given the fact you would be paying for a vapor barrier. If you are thinking about using the Kraft facing for fastening the insulation to the studs, you should purchase QuietZone® insulation rather than Kraft-faced batts.
