Factory-built steel smokeshafts need to be avoided getting in touch with insulation by a minimal 75 mm (3 in.) unless otherwise specified by producer or local authorities.

A radiation obstacle creates a 75 millimetre or 3-inch air room around the chimney and expands 75 millimetres or 3 inches above the attic insulation, keeping the range from combustible materials. The top of the barrier is a tornado collar secured, not sealed, to the chimney. Over the ceiling, the air and vapour obstacle is wrapped around the drywall to contact the firestop sealant.


A collar-like ceiling trim plate is attached below the firestop. Job safely around electric circuitry (switch off the power).
