What are Casement Windows?

Casement windows are attached to the frame by hinges on one side, and they open outward like doors (windows that are hinged on top are called awning windows). They are typically opened by turning a crank—hence their common nickname, "crank windows"—and held open by a casement stay↗

Because casement windows are available in a wide ranges of sizes and configurations, they are ideal for almost any room in the home including those that require egress windows. They're especially popular in rooms where you might want more airflow (i.e. bedrooms, bathrooms) and in places like dining rooms and sitting rooms, where you can enjoy the great view they provide. 

How are Casements Used?

Casement windows are often installed as single units or in pairs but there are many configurations.

  • You'll often see two casement windows within a single frame, in this situation they are hinged on opposite sides so that they both open from the center of the frame. 
  • It's also fairly common to see two casement windows installed on either side of a large picture window. 
  • Casement windows are also used in combination with other window styles like awning windows.
  • Some homeowners even opt for configurations with three or more consecutive casement windows are used, in this case the windows are usually hinged on the same side.

Pros and Cons of Casement Windows

The advantages of casement windows make them ideal for many situations, but not all. Carefully weight the benefits and potential disadvantages of casement windows before choosing them, or before deciding where to install them: 

Pro: The Air Flow Is Unmatched

Few if any other window styles offer as much unobstructed air flow as a casement window. That makes them ideal for warm climates and rooms where you'd like to enjoy the breeze. 

Pro: Casement Windows Are Versatile

Available in a wide range of sizes, shapes and configurations, casement windows have an incredible range of uses, and can be adapted to practically any room in your home. They also fit in with a wide variety of architectural styles, from craftsman homes and prairie-style houses to colonial mansions and contemporary architecture. 

Pro: You Can Enjoy a Great View

Casement windows don't have meeting rails like hung or sliding windows. Without the meeting rails casement windows are able to provide a clear and unobstructed view which is especially beneficial if you want your windows to frame the views outside of your home.

Pro: Casement Windows Are Efficient

Because of the way casement windows open and close, they are able to shut tightly and lock into place without the need for a flexible seal. This makes them extremely weathertight and more energy efficient than sliding windows and many other types. 

Con: They Can Get In the Way

Be careful about installing casement windows on the first floor in a high-traffic area. Casement windows can become hazards if they open into a frequently-used sidewalk or patio, or an area where kids often play. 

Con: Watch Out for the Wind

Casement windows are vulnerable to damage in high winds, much in the same way the wind can catch a door and slam it open. If you have casement windows, it's best to keep them closed on very windy days.
