Please can someone from NCARB confirm NCARB's position, literally, on the placement of the vapor barrier for different climates. I have been on an ARE facebook account and have had different feedback from people in New Orleans, NY, CA etc on location of barriers, both air and vapor barriers. Add the proliferation of air tight insulation to confuse it all.
It's recurring question in the practice exams as to where to put the VB. For NCARB and the ARE, can we agree that VB goes on the warm side, be it exterior side in humid climates and interior side temperate climates. My remaining question is when you get mixed climates as I have seen that question come up too. I am hoping that posting here on NCARB site will get some definitive answer for the exam.
