The top of the barrier is a tornado collar secured, not sealed, to the smokeshaft. Above the ceiling, the air and vapour barrier is twisted around the drywall to call the firestop sealer.


A collar-like ceiling trim plate is attached listed below the firestop. Work safely around electrical circuitry (shut off the power).
