A radiation barrier creates a 75 millimetre or 3-inch air space around the chimney and prolongs 75 millimetres or 3 inches above the attic insulation, maintaining the range from combustible materials. The top of the obstacle is a tornado collar secured, not secured, to the smokeshaft. Above the ceiling, the air and vapour obstacle is twisted around the drywall to call the firestop sealer.
A collar-like ceiling trim plate is connected listed below the firestop. Job safely around electrical circuitry (switch off the power).

Houses with peaked roofing systems and obtainable attics are the simplest to vent by utilizing the ratio of 1 to 300. This ratio describes unblocked air vent location to the shielded ceiling location.
Also, do not use electric exhaust fans for attic air flow as these can attract more air than can be provided through the soffit vents.
