An air and vapour barrier covers the floor of the attic space and is secured to the joists with acoustical sealant. Factory-built metal smokeshafts ought to be maintained from contacting insulation by a minimum 75 mm (3 in.) unless or else specified by maker or regional authorities.

Getting The Green Attics To Work

The top of the radiation shield must likewise be a minimum of 75 mm (3 in.) more than the degree of existing or new insulation to be included. To avoid insulation from falling behind the guard, attach a clamp-type storm collar without sealer on top of the radiation guard, as received Number 5-4.

The top of the obstacle is a tornado collar clamped, not sealed, to the chimney. Above the ceiling, the air and vapour obstacle is covered around the drywall to get in touch with the firestop sealer.

Around the smokeshaft.

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

There is frequently a void in between the event wall (such as the shared wall surface in between units in duplexes, triplexes and row homes) and the side of the attic flooring.


A hefty polyethylene sheet which is caulked with acoustical sealant and stapled to the ceiling encloses the electric box. An electric wire diverts from the electric box and down with an opening right into an indoor wall. Holes around electric wires are full of caulking or foam sealer, and caulking seals gaps along the top of the indoor wall surfaces.

The 8-Minute Rule for Green Attics

After air securing, attic ventilation is your 2nd line of defence against the water vapour that might have discovered its means into the attic. It makes sure a colder, well-vented attic area much less vulnerable to the development of ice dams at the eaves.

This ratio refers to unhampered vent location to the protected ceiling location.


Do not use electrical exhaust fans for attic room air flow as these can attract more air than can be provided via the soffit vents. This will in fact pull home air right into the attic, leading to better warmth loss and wetness buildup. They are likewise vulnerable to failure, sound manufacturing and increased energy usage.
