The top of the obstacle is a storm collar clamped, not sealed, to the chimney. Over the ceiling, the air and vapour barrier is twisted around the drywall to get in touch with the firestop sealer.


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

This ratio describes unblocked air vent location to the shielded ceiling location.


Also, do not utilize electric exhaust followers for attic room ventilation as these can attract a lot more air than can be supplied with the soffit vents. This will actually pull residence air into the attic, leading to better warmth loss and moisture buildup. They are likewise vulnerable to failure, noise manufacturing and increased power usage.
