An air and vapour obstacle covers the floor of the attic room and is sealed to the joists with acoustical sealer. Factory-built steel chimneys need to be kept from contacting insulation by a minimum 75 mm (3 in.) unless or else specified by manufacturer or neighborhood authorities.

The top of the radiation guard should likewise be a minimum of 75 mm (3 in.) greater than the degree of existing or brand-new insulation to be included.

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

There is typically a space between the party wall surface (such as the common wall between devices in duplexes, triplexes and row homes) and the side of the attic floor.


A hefty polyethylene sheet which is caulked with acoustical sealer and stapled to the ceiling encases the electric box.
