The top of the obstacle is a storm collar secured, not sealed, to the chimney. Over the ceiling, the air and vapour barrier is wrapped around the drywall to call the firestop sealant.

This proportion describes unblocked air vent location to the insulated ceiling location.


Do not use electric exhaust followers for attic room air flow as these can attract much more air than can be provided through the soffit vents.
