Factory-built steel chimneys should be maintained from calling insulation by a minimal 75 mm (3 in.) unless otherwise defined by supplier or neighborhood authorities.

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

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


Additionally, do not make use of electric exhaust fans for attic room ventilation as these can draw a lot more air than can be provided via the soffit vents.
