An air and vapour obstacle covers the flooring of the attic room space and is secured to the joists with acoustical sealer. Factory-built steel smokeshafts should be kept from getting in touch with insulation by a minimal 75 mm (3 in.) unless or else defined by producer or local authorities. Set up a non-flammable radiation shield that keeps a 75-mm (3-in.) air area in between the chimney and insulation.

Getting The Green Attics To Work

The top of the radiation shield must also be a minimum of 75 mm (3 in.) more than the degree of existing or new insulation to be included. To stop insulation from falling behind the shield, attach a clamp-type tornado collar without sealer at the top of the radiation shield, as displayed in Figure 5-4.


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


A collar-like ceiling trim plate is connected below the firestop. Typical indoor recessed lights are tough to air seal effectively and can come to be a fire danger if covered with insulation.

Around wires or ceiling lights that permeate the attic room flooring and dividers and exterior wall leading plates (see Figure 5-7 and Number 5-8).




Structure codes require that air areas between chimneys and floor or ceiling settings up via which they pass be secured with a non-combustible fire stop (see Figure 5-3 and Figure 5-4). There is typically a space between the celebration wall surface (such as the common wall in between systems in duplexes, triplexes and row residences) and the side of the attic room floor.

The Basic Principles Of Green Attics

A hefty polyethylene sheet which is caulked with acoustical sealant and stapled to the ceiling encloses the electrical box. An electrical wire diverts from the electrical box and down through a hole right into an indoor wall surface. Holes around electrical wires are loaded with caulking or foam sealer, and caulking seals voids along the top of the interior wall surfaces.


Attic ventilation serves a variety of objectives. It decreases summertime warmth buildup, lengthening the life of roof covering and minimizes air conditioning system loads. After air securing, attic air flow is your second line of defence against the water vapour that may have found its way right into the attic room - Home energy efficiency. It guarantees a cooler, well-vented attic room space much less vulnerable to the formation of ice dams at the eaves.

If the attic retrofit is being completed along with interior renovations, the simplest method is to mount a new, single air and vapour obstacle on the bottom of the ceiling joists


Structure codes require that air areas between chimneys and floor or ceiling settings up with which they pass be sealed with a non-combustible fire stop (see Number 5-3 and Figure 5-4). There is often a space between the party wall (such as the shared wall between systems in duplexes, triplexes and row residences) and the side of the attic floor.


A heavy polyethylene sheet which is caulked with acoustical sealant and stapled to the ceiling encloses the electrical box. An electric wire leads away from the electrical box and down with a hole into an interior wall surface. Holes around electric cords are full of caulking or foam sealant, and caulking seals voids along the top of the indoor wall surfaces.

Green Attics for Beginners

After air sealing, attic ventilation is your 2nd line of defence versus the water vapour that might have discovered its way into the attic room. It ensures a colder, well-vented attic space less vulnerable to the development of ice dams at the eaves.

Houses with peaked roofs and easily accessible attic rooms are the most convenient to vent by utilizing the ratio of 1 to 300. This ratio refers to unhampered air vent area to the shielded ceiling area.


Additionally, do not make use of electrical exhaust fans for attic room ventilation as these can attract a lot more air than can be provided through the soffit vents.

If the attic retrofit is being check here finished together with indoor restorations, the simplest approach is to set up a brand-new, single air and vapour barrier on the underside of the ceiling joists.
