Egress Window Buying Guide: Your Escape Plan Just Got an Upgrade

Being prepared for an emergency should be your number one priority if you own a home. Building codes typically require basements, bedrooms, and living spaces to have a way out. Give your home an emergency exit with an egress window. They are called that because egress means exit or a way out. This guide will discuss what an egress window is, the different types, building requirements, and installation tips.

To put it simply, an egress window is an emergency exit. Their main purpose is to provide an emergency way out in case your primary exit is blocked, such as during a fire. Firefighters and first responders can also use them as an entryway. They also add natural light, ventilation, and increase property value. While most commonly used in a basement, they can be used in other rooms. This page will focus on basement egress windows.

If your basement is used as a bedroom, you need to have an egress window to comply with local building codes. Without egress windows, your home will violate fire safety standards. If there is a fire, occupants and the smoke will be trapped inside. Basements cannot be listed as a habitable bedroom without an egress window. This will lower your home's value should you try to sell it.

Bedrooms are typically required to have at least one egress window, but the exact number varies based on local building codes and the size of the room. An egress window is not always required in a basement if there is no bedroom.

Building codes are designed to allow anyone in the basement to pass through. Exact size requirements vary by state and municipality, but the International Building Code recommends that egress windows have:

• An opening no higher than 44 inches from the floor
• Be 20 inches wide by 24 inches high
• Have a clear opening of 5.7 square feet

Always consult local building authorities before installing egress windows in your basement to ensure compliance with building codes.

Installing an egress window in your basement is not an easy task. Before starting, consider the labor and money that will go into it.

You may need to install a window well because egress windows are beneath ground level. Window wells have steps or a ladder to help you climb safely out of the basement. It is important to facilitate proper drainage and waterproofing during this stage.

A grate or cover will prevent accidents and unauthorized access. They can be opened from the inside. The money you spend will depend on the type of window, labor required, and whether you do it yourself or hire a professional. Consider everything before starting.

Do not attempt to install an egress window by yourself unless you are sure you know what you are doing and you have expert knowledge of home construction, building codes, and proper installation methods. While doing it yourself will save money, improper installation will cause problems later on.

1. Choose the Ideal Location
   • Select a location with an unobstructed escape path.
   • Avoid spots near downspouts or any low-lying areas that may collect water.
2. Excavate and Mark the Opening
   • Dig out the area for the window well.
   • Mark the wall opening according to local building code requirements.
   • Double-check that the dimensions meet the minimum height and width requirements for egress.
3. Carefully Cut the Wall Opening
   • If cutting through concrete, use a masonry saw with a diamond blade.
   • Wear safety gear and take precautions to avoid compromising the structure.
4. Install the Window and Well
   • Set the window in place and ensure it is level and properly shimmed.
   • Use fasteners appropriate for your foundation type.
   • Securely attach the window well and backfill with gravel for drainage.
5. Seal and Insulate Properly
   • Use waterproof flashing and high-quality sealant around the window.
   • Insulate any gaps to improve energy efficiency and block drafts.
6. Ensure Adequate Drainage
   • Install a drain at the base of the window well.
   • Connect the drain to your home's drainage system if necessary to prevent water buildup.

Below is a guide to the two most common types of egress windows.

Casement Egress Windows

Also known as in-swing egress windows, these windows that roll out are hinged on one side and open towards the outside like a door. Because they can open completely, they offer great ventilation. Casement egress windows are great for those who do not have a lot of wall space because they open outward.

Basement Sliding Egress Windows

In sliding egress windows, two sashes slide horizontally and overlap each other. If you are interested in sliding windows, remember that because they slide open, building codes require a bigger space. The code refers to the size that the window opens to, not the window itself. Sliding basement windows must be wider since the opening is roughly half as wide as the window. A 20-inch opening width, for instance, would require sliding windows in your basement that are approximately 40 inches wide. Sliding windows are preferred when outside space is limited.

While egress windows make your basement safer, they also add to your home's energy efficiency. Wellcraft egress windows come with 3/4-inch insulated Low-E glass, which blocks out the sun's ultraviolet and infrared rays. This brings in heat during winter and reflects it during the summer.

A basement egress window is essential to provide a safe escape route for you and your residents in the event of a fire. If you plan to install the window yourself, follow local building codes and adhere to a safe installation process. Decide which type of egress window is best for your basement based on the space available.
