Factory-built steel smokeshafts need to be avoided contacting insulation by a minimal 75 mm (3 in.) unless or else defined by supplier or regional authorities.

A radiation obstacle produces a 75 millimetre or 3-inch air room around the chimney and extends 75 millimetres or 3 inches over the attic room insulation, maintaining the range from combustible products. The top of the barrier is a tornado collar clamped, not secured, to the chimney. Over the ceiling, the air and vapour barrier is twisted around the drywall to call the firestop sealant.


A collar-like ceiling trim plate is affixed below the firestop. Job securely around electric wiring (switch off the power).

Around the chimney. Building ordinance require that air spaces between chimneys and flooring or ceiling assemblies whereby they pass be sealed with a non-combustible fire stop (see Number 5-3 and Figure 5-4). Along the edge of common wall surfaces. There is frequently a gap between the party wall (such as the common wall in between systems in duplexes, triplexes and row residences) and the edge of the attic room flooring.


A heavy polyethylene sheet which is caulked with acoustical sealer and stapled to the ceiling frames the electric box. An electrical cable leads away from the electrical box and down through an opening into an indoor wall surface. Openings around electrical cords are full of caulking or foam sealant, and caulking seals voids along the top of the interior walls.

This will really pull house air into the attic room, resulting in higher heat loss and moisture build-up. They are likewise prone to failure, sound production and raised power usage.
