Ceiling service cavity
I’m sold on having a service cavity. In the walls, it’s easy to see how to implement one with double stud walls but. However the ceiling is not so apparent. Is it easier to delay building interior partitions till after the trusses are in place and the air barrier material installed on their bottoms? Should the interior partitions be the same height as the exterior walls or only to the bottom of the cavity? Is there a “preferred method of attaching the “ceiling joists”?
