What is an Egress Window?

Egress windows are not just an architectural feature — they are a crucial safety component for homes, especially in basement spaces and areas below ground level. These windows provide emergency exits, allowing occupants to escape quickly in dangerous situations, such as fires. But beyond safety, egress windows can improve natural light, enhance ventilation, and even add value to a home. In this comprehensive guide, we will explain what egress windows are, when they are needed, their regulatory requirements, the installation process, costs, and common mistakes to avoid.

Key Takeaways:

• Egress Windows : are required by building codes in specific areas, primarily for safety and emergency evacuation.
• Size and Operation : Egress windows must meet minimum size, height, and operability requirements to ensure safe escape.
• Installation Process : This is a complex process requiring professional expertise, often involving excavation and structural modifications.
• Legal Compliance : Understanding the legal requirements is critical to avoid fines or complications when selling a property.
• Cost and Value : Egress windows are an investment in safety, ventilation, and home value, with costs that can vary depending on factors such as installation complexity.

What is an Egress Window and Why is it Important?

An egress window is a window specifically designed to provide a means of escape from a room in the event of an emergency, such as a fire. These windows are commonly found in basements or bedrooms, where escape routes might otherwise be blocked. Unlike standard windows, which are primarily designed for ventilation or light, an egress window must meet specific size, operability, and accessibility criteria.

Why Are Egress Windows Essential?

1. Safety : In the event of a fire or other emergency, an egress window provides a second escape route, which could be life-saving.
2. Legal Requirement : In Canada, building codes mandate the installation of egress windows in certain rooms, particularly in basements and bedrooms. Not having these windows could result in safety hazards and legal issues.
3. Natural Light & Ventilation : Apart from safety, egress windows provide natural light and airflow, improving the overall quality of life in spaces that might otherwise be dark and stuffy.

Egress Window Requirements: Building Codes and Regulations

In Canada, egress windows are regulated by national and provincial building codes to ensure that they provide safe exits in an emergency. These codes are strict to ensure that the windows meet the necessary size and operation requirements. Below are the essential criteria that an egress window must meet according to most Canadian building codes:

1. Minimum Size Requirements

• Opening Area : An egress window must provide a minimum opening of 5.7 square feet (0.53 m²). This ensures enough space for an average adult to escape quickly.
• Height and Width : The height of the window opening must be at least 24 inches (61 cm), and the width must be at least 20 inches (50 cm). The total opening should allow easy access.

2. Accessibility

• Height from Floor : The bottom of the window opening must be no more than 44 inches (112 cm) from the floor to ensure accessibility for all individuals, including children and seniors.
• Openness Mechanism : The window must open easily without the use of keys, tools, or special knowledge. This ensures that the window can be used quickly in an emergency.

3. Location

Egress windows are required in specific locations within a house, typically in:

• Basements : Any finished basement used as a living space.
• Bedrooms : Bedrooms, especially those located on the lower levels, must have an egress window to comply with safety regulations.

Egress Window Installation: Step-by-Step Guide

Installing an egress window is a detailed process that requires careful planning and professional expertise. Below is a step-by-step breakdown of how egress windows are installed.

Step 1: Determine the Best Location

Choosing the correct location is crucial. The egress window should be positioned to allow a clear and unobstructed escape route. It’s typically placed in basements or bedrooms, with careful consideration given to the room's layout and foundation.

Step 2: Select the Right Window Type

The window selected for installation should meet the required size specifications and be easy to open and close. Casement or sliding windows are often chosen for their ability to open fully, providing easy access.

Step 3: Excavation and Framing

The installation of an egress window typically requires excavating around the house's foundation. This process involves cutting into the foundation to create an opening large enough to accommodate the window. A structural engineer or an experienced installer is required to assess the impact on the foundation and ensure the structure's integrity is maintained.

Step 4: Window Installation

Once the opening is prepared, the window is installed and securely fastened to the frame. The window is sealed to prevent drafts and water infiltration. Proper insulation is also applied to ensure energy efficiency.

Step 5: Backfilling and Finishing

After installation, the area around the window is backfilled with gravel or soil to ensure proper drainage. Any interior finishing is completed to match the room's aesthetics, while also ensuring proper safety and operational functionality.

Cost of Installing Egress Windows: What to Expect

The cost of installing an egress window can vary greatly depending on several factors, including the type of window, the location of the installation, and the complexity of the excavation. Here’s a general breakdown of costs:

• Basic Installation : The cost for installing a single egress window in a basement can range between $2,000 to $5,000, depending on the size and location.
• Additional Costs : More complex installations, such as those requiring significant excavation or structural reinforcement, can increase the cost to $6,000 or more.
• Standard Window vs. Egress Window : Standard window installations are typically much cheaper, ranging from $500 to $1,500. However, egress windows provide additional safety and functionality, making them a worthwhile investment.

Common Mistakes to Avoid During Egress Window Installation

1. Ignoring Building Codes : Failing to meet local building code requirements can result in fines, safety hazards, and complications when selling your home. Always ensure compliance with the relevant regulations.
2. Improper Window Size : Installing a window that doesn’t meet the minimum size requirement can compromise safety and prevent the window from functioning properly as an emergency exit.
3. Not Consulting Professionals : Installing an egress window requires structural changes to your home, including excavation and possibly foundation work. Always hire an experienced professional to ensure that the installation is done correctly.
4. Poor Sealing and Insulation : If the window is not sealed correctly, it could lead to drafts, water damage, and energy loss. Proper insulation and sealing are essential for both safety and energy efficiency.

Case Study: How Egress Windows Saved the Jones Family’s Home
