Factory-built steel chimneys must be avoided speaking to insulation by a minimal 75 mm (3 in.) unless or else defined by maker or neighborhood authorities.

A radiation obstacle develops a 75 millimetre or 3-inch air space around the smokeshaft and extends 75 millimetres or 3 inches above the attic insulation, preserving the distance from flammable materials. The top of the obstacle is a storm collar clamped, not secured, to the smokeshaft. Above the ceiling, the air and vapour obstacle is wrapped around the drywall to contact the firestop sealant.


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

Around cables or ceiling light fixtures that penetrate the attic floor and partition and outside wall leading plates (see Number 5-7 and Number 5-8).




Around the chimney.

This ratio describes unhampered air vent area to the insulated ceiling area.


Additionally, do not utilize electric exhaust fans for attic room air flow as these can draw more air than can be supplied with the soffit vents. This will really draw residence air right into the attic, resulting in higher heat loss and dampness buildup. They are also prone to failing, sound manufacturing and enhanced power use.
