I only have one room with a vaulted ceiling and am looking for suggestions on how to air-seal this room which is bumped out from the plane of the rest of the house (please see pics). Overall, I am planning to use the sheathing as my primary air barrier and my drywall as my secondary barrier. The wall will be 2×6 studs with fiberglass batts sheathed with OSB that will be taped and sealed. I plan to use a vented roof with fiberglass batts for the ceiling and I am in zone 4a.
Looking for advise on how to air seal this room so that it integrates into the rest of the structure.
Thanks!

BrunoF,
What specific problem are you anticipating with this space? The exterior walls get treated just like all the rest - that is the sheathing is sealed, and the drywall acts as your secondary air-barrier. Similarly, the ceiling gets air-sealed by whatever method you are using for the non-vaulted trusses on your main roof.
