Zone 6 R-Sheathing
I am currently constructing a home in North Dakota (Zone 6). We used Zip R6-Sheathing (R 6.6) and plan to used fiberglass bats in the 2×6 walls (not yet installed). The front wall is actually 2×8 due to some big windows.
Our intent was to create a tight, energy efficient home, and to deaden sound; however, now that we have the sheathing on and are siding, I have read people stating that R-sheathing is not well suited for cold climates and that we should have used a thicker foam and placed it on the exterior side of the sheathing.
So my question is this: What should we do, at this point, to ensure our walls do not have moisture issues or that they dry appropriately when moisture does enter the wall? For what it is worth, the siding is LP Smartside.
Thanks in advance!
