Can Casement Windows Be Used for Egress?

Casement windows are typically admired for their sleek design and excellent ventilation. But did you know they can also be used for egress purposes? The key here is ensuring they meet specific requirements for size, operability, and accessibility.

Egress windows serve a critical role in emergencies, such as fires, by offering a safe escape route. Casement windows, which are hinged on the side and open outward like a door, can be adapted to serve this purpose effectively. As long as they meet local building codes and regulations, casement windows can indeed double as egress windows.

The trick to making a casement window suitable for egress is ensuring the window opens fully, providing a large enough exit path. The window must be accessible without requiring tools or special knowledge, which is something homeowners should keep in mind during installation.

What is the Difference Between Egress and Casement Windows?

At first glance, it may seem like “egress” and “casement” refer to two different things. In reality, they’re more like overlapping concepts. So, what’s the difference?

1. Egress Windows:

Egress windows are designed with safety as their primary focus. They ensure that in an emergency, such as a fire, residents can easily exit the home. Egress windows must meet specific size criteria, as defined by local building codes, to ensure a full-sized adult can comfortably fit through them. These windows are often required in bedrooms, basements, and other areas where an additional exit is necessary for safety.

2. Casement Windows:

Casement windows are a type of window with a sash that is hinged on one side, opening outward like a door. They are known for their great ventilation and energy efficiency, as they seal tightly when closed. While casement windows aren’t automatically classified as egress windows, they can be adapted to meet egress standards.

The key takeaway is that casement windows, with the right modifications, can double as egress windows, giving you the best of both worlds—safety and style.

What is the Egress Code for Windows in Canada?

Egress codes are in place to ensure that all windows used for emergency exits provide enough space for a safe escape. While the specific egress codes can vary slightly across different provinces and territories in Canada, there are some general rules you should be aware of.

1. Size Requirements:

The opening of an egress window in Canada must be at least 550 mm (21.7 inches) wide and 900 mm (35.4 inches) tall. This ensures that an adult can exit through the window safely. These dimensions apply to the clear, unobstructed opening—so hardware, window frames, or latches that take up space are not included in the measurement.

2. Location:

Egress windows are required in sleeping areas, such as bedrooms, and in basements where people might spend extended periods. This makes it easier for people to escape quickly in case of an emergency. Keep in mind that basement egress windows may also need window wells to provide a clear path outside.

3. Unobstructed Pathway:

The path from the window to the outside should be free from obstructions, allowing for a fast, unhindered exit.

4. Operability:

Egress windows should open easily without the use of tools or keys. In the case of casement windows, they should be hinged on the correct side and not require excessive force to operate.

5. Safety Latches and Bars:

If the window is in an area with small children, you may need to install safety latches or bars, but these must be easy to release in case of an emergency.

What Type of Windows Can Be Used for Egress?

When it comes to egress windows, you actually have a few options, depending on your needs and the style of your home. Let’s look at the most common types of windows that can be used for egress:

1. Casement Windows:

As discussed earlier, casement windows can be adapted for egress use. They’re a popular choice due to their energy efficiency and sleek design.

2. Double-Hung Windows:

Double-hung windows, where both the upper and lower sashes slide vertically, are another common option. They allow for excellent ventilation and, if designed with a large enough opening, can meet egress requirements.

3. Slider Windows:

With one fixed sash and one that slides horizontally, slider windows are also a good option for egress. They offer ease of use and can meet the necessary size requirements.

4. Awning Windows:

While not as commonly used for egress, awning windows (which open outward from the bottom) can be a solution in some cases.

5. Hopper Windows:

Hopper windows are small windows that open inward from the top, typically used in basements. They’re compact and can be a smart choice for basement egress windows, provided they meet the necessary dimensions.

What Size Casement Window Meets Egress?

If you’re set on using a casement window for egress purposes, you’ll need to pay attention to the window size. The minimum clear opening for an egress window in Canada is 550 mm (21.7 inches) wide and 900 mm (35.4 inches) tall.

The size requirements are strict to ensure that even an adult can easily escape through the window during an emergency. When you’re choosing a casement window, you’ll want to make sure that the frame and any hardware don’t block the opening, reducing the clear space to below the minimum size.

What Type of Window is Best for Basement Egress?

When it comes to basements, the rules for egress windows are no different, but the challenges can be unique. Basements are often lower to the ground and may require additional considerations, such as window wells.

1. Hopper Windows:

Hopper windows are hinged at the bottom and open inward. They are a great option for basements due to their compact design.

2. Slider Windows:

Slider windows, with one sash that slides horizontally, offer a wider opening, making them a good choice for basement egress windows.

3. Double-Hung Windows:

Double-hung windows, which have two sashes that slide vertically, can also meet egress requirements for basements, as long as they provide enough space for a clear opening.

4. Window Wells:

In many cases, basement egress windows require window wells, which provide the necessary space outside the window for easy escape.

5. Egress Window Covers:

Window wells may also need covers to keep out debris and water. These covers must be easy to remove from the inside in case of an emergency.

Conclusion

Egress casement windows strike the perfect balance between safety and style, making them a popular choice for homeowners. With the right size and installation, casement windows can easily fulfil egress requirements while maintaining their sleek and modern look.
