Factory-built steel chimneys should be avoided contacting insulation by a minimal 75 mm (3 in.) unless otherwise defined by maker or regional authorities.

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

A hefty polyethylene sheet which is caulked with acoustical sealer and stapled to the ceiling encases the electric box. An electrical cable diverts from Resources the electric box and down via a hole right into an indoor wall surface.

There is commonly a gap in between the event wall surface (such as the common wall in between units in duplexes, triplexes and row houses) and the side of the attic floor.


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