About this episode
The boys start with a really cool problem-solving involving a monopoly framing, big overhangs, and thermal bridging. And the follow-up is an excellent question from Western Canada regarding the use of ZIP sheathing with a Class I interior vapor retarder. It's a great discussion involving R-values, air barriers, vapor permeability (including all Classes of vapor retarders), wetting, and drying. Whew! Good thing that Steve had a "great" joke to close this one out...(gag).
