Safety should be a top priority when designing or renovating your home, and that’s where egress windows come in. Specifically designed to open quickly and easily during emergencies, these windows provide a vital escape route in situations like fires or floods. Installing egress windows not only enhances your home’s safety but also offers peace of mind, knowing you're prepared for the unexpected.
What Is an Egress Window?
Egress windows are windows that can serve as an exit route during an emergency. They’re designed to open easily and provide enough space for a person to fit through, allowing the occupants inside to escape.
Having a window that opens quickly and effortlessly during a time of crisis has always been important. But today, egress window dimensions are governed by code and – thanks to modern technology – they’re strong and functional without sacrificing aesthetic appeal.
Egress Window Requirements to Meet Code
If you’re thinking about egress window installation, you should first familiarize yourself with local building codes. These codes vary by state and region, so there’s no comprehensive list of regulations. Here are a few common rules:
- One must be able to open the window without using a tool.
- The minimum well requirement is 9 square feet.
- Must have at least 24 inches of net clear opening height. (Keep in mind this isn’t the height of the window itself. It’s the height of the actual opening that a person could fit through in an emergency.)
- Must have at least 20 inches of net clear opening width.
- Sill must be no more than 44 inches from the floor.
- There must be 5.7 feet of total clear opening.
For more information on dimensions and other regulations, check with the Building Department of your local city or county.
Types of Egress Windows
Egress windows can be found in any room in the house, though they are most commonly installed in basements and bedrooms. (In fact, most regulatory agencies require them in these locations.) Choosing the right egress window for your home starts with understanding your options.
Casement
Casement windows are an excellent option for egress windows, particularly in bedrooms where they are commonly found. Their design makes them one of the easiest window types to operate, requiring just a simple turn of a hand-crank to open. This combination of practicality and ease of use makes them a smart and reliable choice.
Single-Hung
One of the most common types of windows, single-hung windows are the perfect egress window size because they typically have a large enough opening. Like a casement window, they open rather easily – you just unlock it and push up the lower sash – so they’re a good choice for an egress window.
Double-Hung
A double-hung window might increase your egress window cost, but you might find that it’s worth it. Double-hung windows have two movable sashes, so you can choose which one to open. This increases ventilation and also makes them easier to clean.
Horizontal Slider
Horizontal slider windows are becoming increasingly more popular over the last few years, particularly in contemporary style homes. They offer a different look than single-hung or double-hung windows, and they provide a great way to ventilate your space.
Does My Basement Need Egress Windows?
If your basement is finished and has liveable space, for example a bedroom, game room, or TV room, it might need egress windows. Horizontal sliders are a popular choice because they come in a wide variety of basement egress window sizes. Casement windows also make good basement egress windows because they’re easy to open and have large openings.
If you’re installing windows in your basement, make sure you’re aware of basement egress window requirements. Talk to an expert about the rules in your area. For example, there may be window well requirements if you don’t have enough clearance outside your windows. That can add to the overall cost of a basement egress window.
Egress Window Installation Process and Cost
So, how much does an egress window cost? And what happens next? The installation process is essentially the same as it is for regular windows. As a result, you shouldn’t expect to see a higher installation cost compared to other types of windows. However, there are exceptions. For example, if the contractor needs to reframe an opening or install an egress window well cover, this could raise the cost.
If you’re doing the installation yourself, then you won’t have to worry about additional charges. But if you are installing the windows, make sure that you have an egress window kit before you get started. This kit should contain all the tools you’ll need.
Window Covers
It’s a good idea to invest in egress window covers, which can be made from a variety of materials, including aluminum, plexiglass, and fiberglass. These covers are usually placed over basement egress windows to protect your windows from destructive storms and falling debris. These covers are also good protection from snow and rain and offer an added layer of energy efficiency and noise reduction.
Egress window covers will add to the cost, especially if you choose one of the more expensive materials. But you might find that it’s worth it if you live in a region that regularly experiences hurricanes or intense storms.
How Much Value Does an Egress Window Add?
Adding egress windows to your home is more than just a safety upgrade—it’s an investment that pays off. As these windows are legally required, they can make your property more appealing to potential buyers—particularly younger families who prioritize safety for their children.
Having egress windows also leads to peace of mind. Knowing that you have a viable escape route should an emergency happen is reassuring, allowing you and your loved ones to rest easy when you’re inside your home.
