Can I finish a room's walls and ceiling by first sealing the walls with 1/2 plywood and then 1/2 drywall? I mean I know I physically can accomplish it, but I'm askign if this might create problems?
A friend mentioned to me that I'd be better doing two layers of 1/2 drywall, since putting ply behind dry may prevent proper humidity transfer, etc. I'm dubious since many people put plastic sheeting as a total vapor barrier behind drywall (at least in basements), so what harm in plywood?
Thanks!
