Can Casement Windows Be Used for Egress?
Casement windows, renowned for their elegant design and excellent ventilation capabilities, can indeed serve egress purposes. Egress windows are defined by their ability to offer a safe and accessible exit in emergencies such as fires or other life-threatening situations. While casement windows open outward on a hinge and might not appear as an obvious choice for egress, they can fulfill this role when designed and installed correctly.
To qualify as egress windows, casement windows must meet specific criteria regarding their size, accessibility, and location within a building. Local building codes and regulations typically define these criteria, which vary from one region to another. To determine whether casement windows can serve for egress in your home, it’s crucial to consult your local building authority or a qualified professional who can assess your specific circumstances.

What Is the Difference Between Egress and Casement Windows?
Understanding the distinction between egress and casement windows is essential to appreciate their compatibility and functionality:
Egress Windows:
- Egress windows are designed primarily for safety and emergency purposes, allowing occupants to exit a building easily in case of fire or other hazards.
- They must meet specific size requirements, which are typically defined by local building codes. These requirements ensure that an average-sized adult can escape through the window comfortably.
Casement Windows:
- Casement windows are a style of window characterized by a hinged sash that swings outward or inward like a door.
- They are known for their energy efficiency, as they provide a tight seal when closed, reducing air leakage and improving insulation.
- Casement windows are often chosen for their aesthetic appeal and unobstructed views, making them a popular choice in various architectural styles.
While egress windows are primarily concerned with safety and meeting specific size criteria, casement windows are a window style that can be adapted to meet egress requirements when necessary.

What Is the Egress Code for Windows in Canada?
Provincial or territorial building codes establish egress code requirements for windows in Canada and may vary from one jurisdiction to another. However, some general principles can help you understand the egress code in Canada:
1. Size Requirements:
Egress windows in Canada must offer a clear opening with a minimum width of 550 mm (21.7 inches) and a minimum height of 900 mm (35.4 inches). These dimensions ensure that an average-sized adult can comfortably exit through the window.
2. Location:
Egress windows should strategically place in sleeping rooms or areas that people might occupy for an extended period. Basements often necessitate egress windows to offer a safe escape route.
3. Unobstructed Pathway:
The pathway from the egress window to the exterior of the building should be clear and unobstructed to facilitate a swift exit.
4. Operability:
Egress windows must be operable without the need for special tools or knowledge. In the case of casement windows, they should be easy to open and not require excessive force.
5. Safety Latches and Bars:
Some egress windows may necessitate safety latches or bars to prevent accidental openings, especially in areas where small children are present.
Keep in mind that these are general guidelines, and consulting your local building authority or a professional is essential for specific egress code requirements in your area.

Hopper windows are hinged at the bottom and open inward from the top. They are often used in basements for egress because they are compact and space-efficient.
The choice of egress window type depends on factors such as the room’s layout, the desired aesthetic, and local building code requirements. Consulting with a professional can help you make the right selection for your specific needs.

What Size Casement Window Meets Egress?
To meet egress requirements, a casement window must offer a clear opening with a minimum width of 550 mm (21.7 inches) and a minimum height of 900 mm (35.4 inches).
