I live in Tennessee. Do I need a vapor barrier on the outside walls and ceiling in the bathroom I am building? Should I use green back drywall board?
If I use green back should I use a vapor barrier? My house is not wrapped in tyvex and has a metal roof without tarpaper under the metal. The bathroom is going in on the second floor. I plan to use cement board in shower area.
