All you need to know about Egress Windows in Canada

Have you ever been involved in a fire accident or any other life threatening incident? In such a situation, you get confused and thinking rationally may be quite challenging. People scramble for the door which in most cases leads to accidents.  Countable people bother to look for exits in buildings. If you have been in such a compromising position before, you know how important an egress window is to a building. You need egress windows in your home to add value to your home and to increase livability and light in most rooms.

Most window companies do not provide clients with adequate information about egress window regulations. In most cases, they end up installing windows that are below the provincial fire code standard. This is not only deadly but also unlawful. We have decided to educate you about egress windows by compiling some of the most important things that you should know about them.

Why you should have Egress Windows

When building homes and offices, your safety matters a lot as much as you care about the architectural designs. Egress windows are required in particular locations in a building. Do you know that these windows must meet specific standards for them to be considered as egress windows? Egress windows provide exit in case of emergency. It is worth noting that safety codes require you to have egress windows in habitable places in your basement or bedrooms.

When to Get Egress Windows

According to the National Building Code of Canada (NBCC), a bedroom window should meet various requirements which are:

  • The window should be large enough such that it can be used as an Emergency Exit. You should be able to open such a window without special knowledge, hardware, tools or keys
  • The window must provide adequate Ventilation throughout the year
  • The window should provide at least 5 percent Light to the entire room

However, these building codes are not the same for all provinces. It is important for you to conduct your research or contact Window Mart to find out the building codes that apply to your area of residence. These regulations may vary even within the same province. Generally, the vertical slider, horizontal slider and casement windows are acceptable as egress windows.

Egress Window Size Limitations

Like earlier mentioned, egress window sizes vary in provinces and cities. It is advisable that you visit your city offices for first hand information. Let’s have a look at the Alberta Building Code (ABC 2014) criteria that all egress windows must satisfy:

  • Unobstructed opening of not less than 0.35 m2 in area with no dimension less than 380 mm (this window should maintain the required opening during an emergency without the need for additional support)
  • All dimensions should be over 15 inches (380 mm)
  • If a window well is required, it must be out from the window at least 760 mm (about 30″) to provide easy exit
  • The window well opening must be more than 30 inches deep
  • 44 inches maximum sill height from the floor level

Important

  • Net clear opening is the actual clear/free space available when you fully open the window.
  • The opening should be large enough to allow people to crawl through.
  • Tools and keys should also not be used to open the window.
  • You are free to install grates and bars as long as keys or tools are not needed to open them.

Other Applicable Rules

  • Egress windows should not be higher than 1.5m above the surface of the floor. The distance should be good enough to allow easy escape even for short people
  • In case you install a sprinkler system in your room, you do not need an outside window for an emergency exit

Differences between Egress Windows and those on Higher Levels

Regardless of your location, the same style and size of windows applies. However, basement windows are generally higher than 1.5 meters above floor level. It is advisable for you to build a step to a high window to allow easy exit incase of fire. Window wells should be located at a minimum distance of 760mm from the window. Basement awning windows are not large enough and do not meet the requirements of building codes.

Should a Special Type of Window be used?

Casement windows can still be used as egress windows although they are relatively small. The hinged sashes of casement windows swing freely. Where space is limited, these windows can serve as ideal egress windows for basements.

Why Most Windows Don’t Meet Egress Requirements

Most older homes were actually built before egress window requirements existed. This means that they did not follow the current egress window requirements. Additionally, some homes were constructed when the standard requirement for egress windows were 5 sq. ft. However, some new homes still lack egress windows. Basements and attics were in most cases remodeled into offices or family rooms but later changed into bedrooms. If you convert your basement into a bedroom without the guidance of an inspector or a certified company such as Window Mart, it can be quite dangerous without a standard egress window. During remodeling, most homeowners tend to replace egress windows with relatively smaller ones that do not qualify to be egress windows.
