Vaulted ceiling-ridge beam sealing at drywall intersection
New construction, PNW zone 4marine.
I have a 14′ high vaulted ceiling (vented roof via channel above using TJI flange) with a large glulam ridge beam. The beam drops down about six inches below where the ceiling plane intersects. On the original plans, the beam is taped and wrapped with drywall. Now that it’s all up there, it would look much, much better to have the glulam beam left exposed.
So the problem is now how to air seal that intersection between the drywall and the side of the beam. Complicating matters is that the hangers for the I-joists are pretty beefy and hold about two or three inches of the bottom flange of the I joist making it difficult/impossible to install blocking there. Besides, I’m not too excited to nail into the sides of the flange for fear of splitting them at a pretty crucial point.
Any good ideas on how to seal this intersection? Drywall beads with gaskets? Eurotapes lapped 1/2″ onto the beam? Caulk?
