You basically use vapor barriers in high humidity climates or maybe some other situations that I may not be so familiar with. I think of it as an additional layer of protection from moisture to catch whatever comes through the insulation. With todays insulation I am not so sure, lots of it is fiber anyways and I dont see how moisture gets through that. Its really a question around insulation more so than what drywall you use. If you are concerned about insulation, enduraflood will not help because remember you dont want to caulk up the seams otherwise you cant get the panels off later.
