In case of a home emergency, it’s important to have multiple escape routes. Egress windows provide an additional option to leave your home quickly and safely. In many municipalities, building codes require homes to have egress windows in certain rooms, especially basements and bedrooms. Have greater peace of mind with our in-depth guide to egress windows.
What is an Egress Window?
Not only do egress windows open wide enough to allow you to crawl out in case of an emergency, but they’re also large enough for first responders and their equipment to enter your home if your entry doors are blocked. When time is of the essence, escaping through your basement or lower-level bedroom window can be a lifesaver.
While added safety is important, egress windows also welcome ventilation and natural light in basements or windowless rooms. Increased circulation can improve indoor air quality, plus the extra light can make small, dark rooms feel less like a dungeon.
Why Do You Need Egress Windows?
Installing egress windows is more than a want—it may be required. By ensuring a safe evacuation plan in case of a fire or other emergency, your home meets the legal and building code requirements in many areas. For more daily use, providing airflow and daylight to dark basement spaces enhances the livability of the spaces you once avoided. Once you’ve converted unfished basements or below-grade rooms into livable spaces, your home’s overall functionality and appeal to potential buyers increases.
Egress Window Size Requirements
To ensure your new egress windows meet all legal requirements, make sure they satisfy the following dimensions and guidelines:
- At least 20 inches wide & 24 inches high for escape
- Opening area of at least 5.7 square feet (or about 820 square inches)
- No more than 44 inches above ground level
- Windows must open fully without obstructions like trees and bushes
Types of Egress Windows
Egress windows come in three main styles—casement, double-hung and sliding. Let’s take a look at the characteristics of each type.
Casement Egress Windows
- Operate with a crank to swing outward
- Offer a wide opening that’s easy to open in emergencies
- Ideal for small or narrow spaces
Double-Hung Egress Windows
- Both sashes are movable to allow for more flexible opening options
- The most popular style due to its aesthetic appeal and ease of use
- Requires ample space for full opening
Sliding Egress Windows
- Open horizontally with one panel sliding over the other
- Great for basements or other spaces with limited height clearance
- Provide a larger opening than other options in certain configurations
Egress Window Installation Considerations
Once you’ve determined which rooms need egress windows, place them based on the room’s layout and emergency accessibility. Hiring a professional will ensure the job is done correctly and up to code from start to finish. They’ll help you determine where egress windows are needed and install them properly, which is especially important in non-standard rooms like basements.
