A radiation barrier produces a 75 millimetre or 3-inch air area around the smokeshaft and expands 75 millimetres or 3 inches above the attic room insulation, preserving the range from flammable materials. The top of the obstacle is a storm collar secured, not sealed, to the smokeshaft. Over the ceiling, the air and vapour barrier is twisted around the drywall to call the firestop sealant.
