Factory-built metal smokeshafts must be kept from speaking to insulation by a minimum 75 mm (3 in.) unless otherwise defined by supplier or regional authorities.

A radiation barrier develops a 75 millimetre or 3-inch air area around the smokeshaft and expands 75 millimetres or 3 inches over the attic room insulation, maintaining the distance from combustible products. The top of the barrier is a tornado collar secured, not sealed, to the smokeshaft. Above the ceiling, the air and vapour barrier is wrapped around the drywall to contact the firestop sealant.


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

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

If the attic retrofit is being finished together with indoor improvements, the easiest approach is to install a new, solitary air and vapour barrier on the underside of the ceiling joists


Around the chimney. Building ordinance need that air spaces between smokeshafts and floor or ceiling settings up where they pass be secured with a non-combustible fire quit (see Figure 5-3 and Number 5-4). Along sites the side of shared wall surfaces. There is usually a space in between the party wall (such as the common wall surface between devices in duplexes, triplexes and row residences) and the side of the attic flooring.


A hefty polyethylene sheet which is caulked with acoustical sealant and stapled to the ceiling frames the electric box. An electric wire diverts from the electric box and down via an opening into an indoor wall surface. Holes around electrical cables are full of caulking or foam sealant, and caulking seals gaps along the top of the interior wall surfaces.
