Can anyone tell me what's the proper way to insulate a cathedral ceiling so I don't end up with condensation problems? I'm building an addition and the rafters are 2"X8". thanks for any help.

I am putting an addition on my home and I've been told to use R-38 in the ceiling, and R-19 in the walls. I put kraft-faced in the ceiling and installed a vapor barrier. After talking to a local inspector, I was told to remove the vapor barrier and either replace the batts with unfaced insulation or basically shred the kraft face with a utility knife and put the barrier back up. Also, in the walls I put in an encapsulated batt (johns-mansville comfort therm) and was told again to shred the face then poly over, or replace with unfaced. I was told this encapsulated product should not even be sold, as it violates local building codes. The inspector said that the vapor barrier would be too much, and I would have moisture problems. HELP!!!
