Cold, wet sheathing on double stud wall?
The exterior sheathing on double stud walls is known gain moisture during winters. The data I've seen is all about "conventional" sheathing choices. There are several brands of fiberglass reinforced gypsum sheathing in the market, being sold as exterior sheathing, all of these products require "bracing" by other means. Denseglass is one brand and it has a moisture permeability of about 20 perms. Does use of fiber glass reinforced gypsum exterior sheathing result in a more resilient assembly than plywood?
