The top of the radiation guard should likewise be a minimum of 75 mm (3 in.) more than the degree of existing or new insulation to be added. To prevent insulation from dropping behind the shield, affix a clamp-type tornado 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 room around the chimney and prolongs 75 millimetres or 3 inches over the attic room insulation, maintaining the range from combustible products. The top of the barrier is a storm collar clamped, not sealed, to the chimney. Above the ceiling, the air and vapour barrier is twisted around the drywall to call the firestop sealer.


A collar-like ceiling trim plate is affixed below the firestop. Conventional interior recessed lights are challenging to air seal efficiently and can become a fire hazard if covered with insulation.

Around wires or ceiling light fixtures that pass through the attic floor and dividers and outside wall top plates (see Number 5-7 and Figure 5-8).




Around the chimney. Building codes call for that air areas between chimneys and floor or ceiling settings up whereby they pass be sealed with a non-combustible fire stop (see Figure 5-3 and Number 5-4). Along the edge of common wall surfaces. There is usually a space between the event wall surface (such as the common wall surface in between systems in duplexes, triplexes and row residences) and the side of the attic room floor.

A hefty polyethylene sheet which is caulked with acoustical sealer and stapled to the ceiling encloses the electric box. An electrical cord leads away from the electrical box and down with a hole right into an interior wall. Holes around electrical cords are loaded with caulking or foam sealer, and caulking seals voids along the top of the indoor walls.


Attic air flow offers a number of functions. It lowers summertime warmth buildup, prolonging the life of roofing and minimizes air conditioner tons. After air sealing, attic ventilation is your second line of defence versus the water vapour that might have found its way into the attic room - HVAC maintenance. It guarantees a colder, well-vented attic room room much less prone to the formation of ice dams at the eaves.




You might need to locate roof covering or soffit vents from outside if they are not clearly visible from inside the attic. Homes with actually peaked roofings and accessible attic rooms are the easiest to vent by making use of the ratio of 1 to 300. This proportion refers to unblocked air vent location to the protected ceiling area.


Additionally, do not use electric exhaust fans for attic ventilation as these can attract extra air than can be supplied via the soffit vents. This will really draw house air right into the attic, leading to better warmth loss and dampness accumulation. They are also susceptible to failing, noise production and enhanced energy use.

If the attic room retrofit is being completed combined with interior improvements, the easiest approach is to mount a new, single air and vapour obstacle on the underside of the ceiling joists


Structure codes need that air rooms in between chimneys and flooring or ceiling settings up via which they pass be sealed with a non-combustible fire stop (see Number 5-3 and Figure 5-4). There is typically 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 flooring.


A heavy polyethylene sheet which is caulked with acoustical sealer and stapled to the ceiling encloses the electric box. An electric wire leads away from the electric box and down with an opening right into an interior wall surface. Holes around electrical cords are filled up with caulking or foam sealer, and caulking seals spaces along the top of the interior walls.

After air sealing, attic room ventilation is your 2nd line of protection versus the water vapour that might have found its method into the attic. It makes sure a chillier, well-vented attic room much less vulnerable to the development of ice dams at the eaves.

Houses with actually peaked roofs and accessible attic rooms are the easiest to vent by utilizing the proportion of 1 to 300. This proportion refers to unblocked air vent location to the protected ceiling area.


Do not use electrical exhaust followers for attic ventilation as these can attract a lot more air than can be provided with the soffit vents. This will really draw home air into the attic, resulting in greater warm loss and wetness buildup. They are also vulnerable to failure, sound production and increased power use.


The following Components detail the finest method depending on your attic type. After you have actually inspected the attic and lugged out any kind of restorative work, focus initially on air and wetness control.

The Main Principles Of Green Attics

On the various other hand, spray foam offers air securing and an initial layer of excellent quality insulation that can be topped approximately the desired RSI (R) degree. If the attic room retrofit is being completed along with interior renovations, the simplest technique is to install a brand-new, single air and vapour barrier on the bottom of the ceiling joists.
