Factory-built steel smokeshafts need to be maintained from calling insulation by a minimum 75 mm (3 in.) unless otherwise defined by supplier or regional authorities.

A radiation barrier produces a 75 millimetre or 3-inch air area around the smokeshaft and expands 75 millimetres or 3 inches above the attic insulation, preserving the distance from combustible materials. The top of the obstacle is a storm collar clamped, not sealed, to the chimney. Above the ceiling, the air and vapour barrier is covered around the drywall to contact the firestop sealant.


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

There is usually a gap in between the party wall (such as the shared wall between units in duplexes, triplexes and row residences) and the side of the attic floor.


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