A casement window is vertically oriented with hinges along the side so it opens outward like a door. It’s crank operated and can also be automated to open with the touch of a button. When it’s open, it lets in fresh air from the top to the bottom. When it’s closed, the sash gets pulled into the frame by the locking hardware, making it one of the most energy efficient window types.
It has a clean look, due to its single sash design, so it works well in more modern homes. But it can also be dressed up with grilles or even to imitate the look of a double-hung window where you want the functionality of a casement with the look of a more traditional window. In short, the casement is an ever-adaptable window option.

As you’ve no doubt gathered, a casement window will work well in a number of different home styles and in a number of different rooms. Still, there are a few places where its shape and functionality make it a particularly natural fit. Here’s where you might consider using a casement window.
Windows in modern homes are typically made for looking through, rather than looking at — think more glass and less framing around the glass. Casement windows have a single sash, so a simpler design than a double-hung window, which has two sashes. (A sash is the glass and framing around it.) Here are a few options to keep in mind when selecting casement windows for a modern home:

Casement windows can be combined with other windows to create a major statement that’s especially impactful in a gathering space like a living room or dining room. The benefits of a window combination unit include the opportunity to bring in lots of light, frame an expansive view, and create a feature that adds character to your home’s exterior.
Because window combinations often feature picture windows, which don’t open, casement windows bring an important element — fresh air! Here are a couple of ideas about using casements in window combinations:
Above a sink, over a counter, or anywhere you must reach to open the window, a casement will be more functional than a hung window. That’s why we love casement windows in kitchens, bathrooms, and more places. Check out the photos below for inspiration.
Yes! Casement windows (along with awning windows) are some of our most efficient windows. This is due to their design and their seal. With only a single sash, there are fewer opportunities for air leakage, and their sealing design tightens when the window blows against them. The only window that’s more energy efficient is the one that doesn’t open — the picture window.
To further maximize your casement window’s energy efficiency, consider these selections:
