Casement windows are a popular choice for homeowners and builders alike due to their versatility, energy efficiency, and aesthetic appeal. However, it's essential to be aware of the egress requirements for these windows, as they play a crucial role in ensuring safety and compliance with building codes. In this blog post, we'll delve into the details of casement window egress requirements, so you can make informed decisions when selecting and installing these windows in your home or building project.
Egress refers to the ability to exit a building or space quickly and safely in case of an emergency, such as a fire. Building codes typically require that every bedroom and habitable space have at least one egress window or door to provide a means of escape. These requirements are designed to ensure that occupants can evacuate the building quickly and safely, and that emergency responders can enter the building if necessary.
Casement windows, which are hinged on one side and swing outward, can serve as egress windows if they meet specific size and operational requirements. The International Residential Code (IRC) and local building codes typically dictate these requirements. While the exact specifications may vary depending on your location, the following are some general guidelines for casement window egress:
To qualify as an egress window, a casement window must have a minimum net clear opening area of 5.7 square feet (5.0 square feet for ground floor windows). This measurement refers to the actual free and unobstructed space that is available when the window is fully open.
In addition to the minimum opening area, egress windows must also meet specific width and height requirements. For casement windows, the minimum net clear opening width is 20 inches, and the minimum net clear opening height is 24 inches. It's important to note that these dimensions refer to the actual opening, not the overall window size.
The sill height of an egress window refers to the distance from the floor to the bottom of the window opening. To comply with egress requirements, the maximum sill height for a casement window must not exceed 44 inches. This ensures that occupants can easily access the window in case of an emergency.
Egress windows must be easily operable without the need for tools, keys, or special knowledge. Casement windows typically meet this requirement, as they can be opened with a simple crank mechanism. However, make sure that the window hardware is in good working condition and that the window can be opened fully and easily.
In addition to meeting the size and operational requirements, it's essential to consider other factors when selecting and installing casement windows for egress purposes:
If your casement window is located below ground level, such as in a basement, you'll need to install a window well to ensure safe egress. The window well must be large enough to accommodate the window's full opening and provide a minimum horizontal projection of 36 inches from the exterior wall.
Make sure that there are no obstructions, such as furniture or window coverings, that could impede access to the egress window. Additionally, ensure that the window's exterior is free of obstructions, such as bushes or fences, that could hinder escape or entry by emergency responders.
If you have security bars or grilles installed on your casement windows, they must be easily removable or operable from the inside without the use of tools, keys, or special knowledge. This ensures that occupants can quickly exit through the window in case of an emergency.
Understanding and adhering to casement window egress requirements is crucial for ensuring the safety of your home's occupants and compliance with building codes. By following the guidelines outlined in this blog post, you can make informed decisions when selecting and installing casement windows for your home or building project. Remember to consult your local building codes for specific requirements in your area, and don't hesitate to consult with a professional if you have any questions or concerns.
Casement windows are the most common style of window. They feature hinged panels that swing open and closed. Casement windows are available in single panels or multiple panels. The direction a door swings, either to the right or the left, is called the handing. In addition to handing, window are identified as either inswing or outswing depending on whether they open into the house or towards the outside.

This newly built private house is in Sydney, Australia. The area occupied by the fenestration system in our scheduled design drawings was up to more than 110 square meters. A wide range of design details made the perfect mix of modern aesthetics and traditional sophistication, the simulated vertical hung windows with tilt & turn opening systems in this home are absolutely breathtaking. SDLS (Simulated Divided Lites with Spacer Bar) brings some historical vintage feeling to the whole building without losing any energy saving performance. Long narrow fixed windows creating larger-than-life expenses, coupled with German high-end systems made this project stand out from the rest.
The client's idea was to maintain a certain vintage feel, and our aim was to meet the energy efficiency needs and standards of modern houses as much as possible while maintaining a retro design. Doorwin’s 61S simulated hung windows with tilt & turn openings is a respectful modernization of a classic architectural masterwork.
Why choose the tilt and turn opening method?
Because it generally has better air seals than sliding, single hung, or double hung window frames. Tilt and turn windows form a complete seal when fully closed, this means they are less prone to water leakage, and cold draughts and you’ll keep more of your heating indoors where it belongs. They can be opened in the upper tilt way to ventilate at a minimum opening status and are easy to clean outside of the glass; when there’s a good day, they can be opened as normal inward casement windows.
Our well-crafted bespoke systems enhance the functionality and panoramic view of this modern house.
Huge, fixed glass walls up to seven meters long and two meters high bring great lighting and open views, making it really refreshing to the mind. Five meters high long narrow windows give the whole building a contemporary aesthetic.
Every window’s placement and shape not only add to the uniqueness of this home but also provide a more energy-saving ability for the owners.
Doorwin energy-efficient integrated glazing units feature double-pane glass, warm-edge spacers, argon gas fill, Low-E coatings, and fully tempered glass, they can not only create a comfortable and natural indoor environment but also save electricity bills and heating bills of more than 100 USD for the owner, it’s a real bargain compared to choosing a regular glazing set.
Aluminum Door offered an air of uniqueness and elegance to a home. With their luxurious patterns and beautiful finishes, it provides this house with a bounty of aesthetics and security.
