T&G cathedral ceiling air barrier question
We are located in the Finger lakes region of NY and are considering T&G cathedral ceiling. Roof assembly would be Zip Roof Sheathing, un-vented roof with 7" of closed cell foam (R-49). I found a company that uses Lapolla Foam Lok 2000 4G foam with climate-friendly blowing agents. Based on this assembly, I am assuming that I would not need a dry wall layer under the T&G; am I correct?
