Wh Where vented dropped ceiling cavities occur over conditioned spaces, the t d d d ili iti diti d th ceiling shall be considered to be both the upper thermal envelope and pressure envelope of the building and shall contain a continuous air barrier between the conditioned space and the vented unconditioned space that is also sealed to the air barrier of the walls. See the definition of air barrier in Section C202. C402.4.9.2 Unvented dropped ceiling cavities. Where unvented dropped ceiling cavities occur over conditioned spaces that pp g p do not have an air barrier between the conditioned and unconditioned space (such as T-bar ceilings), they shall be completely sealed from the exterior environment (at the roof plane) and adjacent spaces by a continuous air barrier that is also sealed to the air barrier of the walls In that case the roof barrier that is also sealed to the air barrier of the walls.
