The top of the obstacle is a storm collar clamped, not sealed, to the chimney. Above the ceiling, the air and vapour obstacle is twisted around the drywall to contact the firestop sealer.

A hefty polyethylene sheet which is caulked with acoustical sealer and stapled to the ceiling encloses the electrical box.
