The top of the obstacle is a storm collar secured, not sealed, to the smokeshaft. Above the ceiling, the air and vapour obstacle is twisted around the drywall to speak to the firestop sealant.


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

This ratio refers to unhampered air vent area to the insulated ceiling area.


Additionally, do not make use of electrical exhaust fans for attic ventilation as these can draw much more air than can be supplied via the soffit vents. This will actually draw house air into the attic room, leading to higher warm loss and moisture accumulation.
