Factory-built steel smokeshafts must be maintained from calling insulation by a minimal 75 mm (3 in.) unless otherwise specified by producer or local authorities.

Along the edge of shared wall surfaces. There is usually a space between the event wall surface (such as the shared wall surface in between units in duplexes, triplexes and row houses) and the edge of the attic room flooring.


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