An air and vapour barrier covers the floor of the attic room area and is secured to the joists with acoustical sealer. Factory-built steel smokeshafts must be avoided contacting insulation by a minimal 75 mm (3 in.) unless or else defined by manufacturer or local authorities. Install a non-flammable radiation shield that preserves a 75-mm (3-in.) air area between the smokeshaft and insulation.

Green Attics Can Be Fun For Everyone

The top of the radiation guard ought to also be a minimum of 75 mm (3 in.) more than the level of existing or brand-new insulation to be added. To stop insulation from dropping behind the shield, affix a clamp-type storm collar without sealer at the top of the radiation guard, as displayed in Number 5-4.


A radiation barrier creates a 75 millimetre or 3-inch air area around the chimney and expands 75 millimetres or 3 inches above the attic room insulation, preserving the distance from combustible materials. The top of the barrier is a tornado collar clamped, not sealed, to the smokeshaft. Over the ceiling, the air and vapour obstacle is twisted around the drywall to speak to the firestop sealant.

Around cables or ceiling lighting fixtures that penetrate the attic flooring and dividing and outside wall leading plates (see Number 5-7 and Number 5-8).




Around the chimney. Building ordinance call for that air rooms in between chimneys and floor or ceiling assemblies via which they pass be sealed with a non-combustible fire stop (see Number 5-3 and Number 5-4). Along the side of shared walls. There is frequently a space in between the celebration wall surface (such as the common wall surface in between devices in duplexes, triplexes and row houses) and the edge of the attic flooring.

Not known Facts About Green Attics

A heavy polyethylene sheet which is caulked with acoustical sealer and stapled to the ceiling encloses the electric box. An electrical wire diverts from the electric box and down with a hole into an interior wall surface. Holes around electrical cords are loaded with caulking or foam sealer, and caulking seals gaps along the top of the interior walls.


Attic air flow serves a number of objectives. It minimizes summer heat build-up, extending the life of roof covering and reduces air conditioning unit loads. After air securing, attic air flow is your second line of support against the water vapour that might have discovered its way right into the attic room - Duct cleaning.

If the attic retrofit is being completed together with indoor remodellings, the most convenient approach is to install a brand-new, solitary air and vapour barrier on the bottom of the ceiling joists


Around the chimney. Building ordinance need that air areas between smokeshafts and floor or ceiling assemblies whereby they pass be secured with a non-combustible fire stop (see Number 5-3 and Number 5-4). Along the edge of shared wall surfaces. There is usually a space between the party wall surface (such as the shared wall surface between systems in duplexes, triplexes and row homes) and the edge of the attic room floor.


A heavy polyethylene sheet which is caulked with acoustical sealer and stapled to the ceiling encases the electric box. An electric cable diverts from the electrical box and down through an opening into an indoor wall. Openings around electrical cables are full of caulking or foam sealer, and caulking seals spaces along the top of the interior wall surfaces.

Green Attics Fundamentals Explained

After air sealing, attic room air flow is your 2nd line of support versus the water vapour that might have located its method right into the attic. It makes certain a colder, well-vented attic room room much less susceptible to the formation of ice dams at the eaves.

Homes with peaked roofings and easily accessible attic rooms are the most convenient to vent by using the proportion of 1 to 300. This ratio describes unobstructed air vent location to the protected ceiling location.


Do not use electric exhaust followers for attic ventilation as these can attract more air than can be provided through the soffit vents. This will really draw house air right into the attic room, resulting in better heat loss and dampness build-up. They are also susceptible to failure, noise production and raised energy usage.


The complying with Parts information the finest technique depending on your attic room kind. After you have actually checked the attic room and carried out any type of restorative job, emphasis initially on air and dampness control.

If the attic room retrofit is being completed in combination with interior remodellings, the easiest approach is to mount a new, solitary air and vapour obstacle on the bottom of the ceiling joists.
