An air and vapour obstacle covers the floor of the attic room space and is secured to the joists with acoustical sealant. Factory-built metal smokeshafts ought to be avoided calling insulation by a minimum 75 mm (3 in.) unless otherwise defined by producer or neighborhood authorities. Install a non-flammable radiation guard that keeps a 75-mm (3-in.) air area in between the smokeshaft and insulation.

The top of the radiation guard should also be a minimum of 75 mm (3 in.) higher than the level of existing or new insulation to be included. To stop insulation from dropping behind the guard, attach a clamp-type storm collar without sealant at the top of the radiation shield, as received Figure 5-4.


A radiation barrier produces a 75 millimetre or 3-inch air area around the smokeshaft and prolongs 75 millimetres or 3 inches over the attic room insulation, maintaining the distance from combustible products. The top of the obstacle is a tornado collar secured, not secured, to the smokeshaft. Over the ceiling, the air and vapour obstacle is covered around the drywall to speak to the firestop sealer.


A collar-like ceiling trim plate is attached listed below the firestop. Typical indoor recessed lights are hard to air seal effectively and can end up being a fire risk if covered with insulation.

Around cords or ceiling lights that pass through the attic room flooring and dividers and outside wall surface top plates (see Figure 5-7 and Figure 5-8).




Building codes call for that air spaces in between smokeshafts and floor or ceiling assemblies via which they pass be secured with a non-combustible fire stop (see Figure 5-3 and Number 5-4). There is commonly a space between the event wall surface (such as the shared wall in between systems in duplexes, triplexes and row houses) and the side of the attic room floor.

The 9-Minute Rule for Green Attics

A hefty polyethylene sheet which is caulked with acoustical sealant and stapled to the ceiling encloses the electric box. An electrical wire leads away from the electric box and down with an opening into an indoor wall. Holes around electric wires are loaded with caulking or foam sealant, and caulking seals spaces along the top of the indoor walls.


Attic air flow serves a variety of objectives. It minimizes summer warm buildup, extending the life of roofing and minimizes ac system loads. After air securing, attic ventilation is your second line of protection versus the water vapour that may have discovered its means into the attic - HVAC installation. It makes certain a colder, well-vented attic area much less vulnerable to the formation of ice dams at the eaves.




You might need to situate roofing system or soffit vents from outside if they are not clearly noticeable from inside the attic room.

This ratio refers to unhampered air vent area to the insulated ceiling location.


Additionally, do not utilize electric exhaust followers for attic room ventilation as these can attract extra air than can be provided through the soffit vents.

Structure codes require that air areas in between chimneys and flooring or ceiling assemblies with which they pass be secured with a non-combustible fire stop (see Number 5-3 and Figure 5-4). There is usually a gap in between the event wall (such as the common wall surface between systems in duplexes, triplexes and row residences) and the edge of the attic flooring.


A hefty polyethylene sheet which is caulked with acoustical sealant and stapled to the ceiling encloses the electric box. An electrical cable diverts from the electric box and down through a hole right into an indoor wall. Holes around electric cords are filled with caulking or foam sealant, and caulking seals spaces along the top of the indoor wall surfaces.

Green Attics - The Facts

Attic ventilation serves a number of explanation purposes. It reduces summertime warm accumulation, extending the life of roof and minimizes air conditioning unit loads. After air sealing, attic air flow is your 2nd line of protection versus the water vapour that may have discovered its method into the attic. It ensures a colder, well-vented attic room room much less susceptible to the formation of ice dams at the eaves.


You may need to situate roof covering or soffit vents from outdoors if they are not clearly noticeable from inside the attic room. Houses with actually peaked roof coverings and obtainable attic rooms are the simplest to vent by utilizing the proportion of 1 to 300. This ratio describes unblocked vent location to the protected ceiling area.


Additionally, do not utilize electrical exhaust followers for attic air flow as these can draw extra air than can be provided through the soffit vents. This will in fact pull home air right into the attic, resulting in better warm loss and moisture buildup. They are also vulnerable to failure, sound production and raised energy usage.


The place of vents is as vital as their number and kind. Often, a mixture of types and locations will work best.
