Particularly if the inside has a poly vapor barrier under the drywall, that wall won't be able to dry to either direction. No wall is perfect under all situations, and a wall that won't dry in at least one direction is a recipe for failure. That wall will have to be detailed very carefully on the inside to prevent any leakage at all of inside air into the cavity in winter to have any chance. The only way this wall will work is if it is spray foamed with closed cell foam.

Good to know. For as much money they are spending I would bet they would use spray foam instead of fiberglass.
