I am building out my basement and am ready to dry wall. For $100.00 more I can dry wall my basement with green board vs regular dry wall. My basement does not leak however there is some humidity in the basement. What are the pros and cons of this move. Also, do I need to slit my kraft faced insulation if I go w/ green borad? I was told that this is necessary to allow prevent condensation in the insulation. Plz let me know.
