An air and vapour obstacle covers the floor of the attic area and is sealed to the joists with acoustical sealant. Factory-built metal chimneys must be maintained from calling insulation by a minimal 75 mm (3 in.) unless otherwise specified by maker or regional authorities. Mount a non-flammable radiation guard that preserves a 75-mm (3-in.) air space in between the chimney and insulation.

A radiation obstacle creates a 75 millimetre or 3-inch air area 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 clamped, not secured, to the chimney. Over the ceiling, the air and vapour barrier is covered around the drywall to speak to the firestop sealer.


A collar-like ceiling trim plate is affixed below the firestop. Job safely around electrical circuitry (turn off the power).

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

Holes around electric cables are loaded with caulking or foam sealant, and caulking seals spaces along the top of the interior wall surfaces.


Attic go to website ventilation serves a variety of purposes. It reduces summer warm accumulation, prolonging the life of roof and lowers air conditioning unit lots. After air securing, attic air flow is your second line of defence versus the water vapour that may have found its means into the attic room - Home energy efficiency. It ensures a chillier, well-vented attic room area less vulnerable to the formation of ice dams at the eaves.

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


A heavy polyethylene sheet which is caulked with acoustical sealer and stapled to the ceiling encases the electric box.
