A radiation obstacle develops a 75 millimetre or 3-inch air space around the smokeshaft and prolongs 75 millimetres or 3 inches over the attic insulation, preserving the distance from combustible materials. The top of the barrier is a tornado collar secured, not sealed, to the smokeshaft. Over the ceiling, the air and vapour obstacle is covered around the drywall to speak to the firestop sealer.


A collar-like ceiling trim plate is attached below the firestop. Job safely around electrical wiring (transform off the power).
