The top of the barrier is a tornado collar secured, not sealed, to the chimney. Above the ceiling, the air and vapour obstacle is twisted around the drywall to contact the firestop sealant.

A collar-like ceiling trim plate is connected listed below the firestop. Work securely around electric wiring (shut off the power).

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

Additionally, do not utilize electrical exhaust fans for attic room air flow as these can draw much more air than can be provided with the soffit vents. This will really draw residence air into the attic, leading to higher warmth loss and moisture accumulation. They are additionally prone to failure, sound manufacturing and enhanced power usage.
