What is a Casement Window?

In its simplest form, a casement window is a window that attaches to its frame by hinges installed on the side. This allows the windows to open outwards instead. Casement windows, however, can differ significantly. Before you choose casement windows for your home, explore your options to decide which one you like most.

Opening Casement Windows

Casement windows often have cranks that control how far they open. The crank also prevents strong winds from blowing windows shut. That’s an important aspect of casement windows. If a strong wind slammed a window shut with great force, then it could damage the frame or cause the glass to break.

With the crank (some have cam handles or levers), people remain in control of the window.

Out-Swinging Casement Windows

Out-swinging casement windows have hinges located on the outside. Placing the hinges in this location allows them to open into the outdoors without damaging the frame.

This is the most popular design for a casement window. Windows that open outwardly take up less interior space than those that open into the home. There are some casement windows, however, that do open inwardly. Regardless of which way the window opens, they are both considered “casement windows.”

Energy-Efficient Casement Windows

Casement windows with two or more frames in them might qualify as energy-efficient windows. Manufacturers often fill the spaces between glass panes with argon gas. This gas creates an additional barrier that prevents the outside temperature from affecting the temperature inside the house. Since homes with these windows don’t have to use as much energy to maintain a constant interior climate, they can lower bills and help protect the environment.

Decorative Casement Windows

Some casement windows have decorative glass that adds something special to homes. Decorative glass can refer to all types of designs. Some casement windows have colored glass. Others have multiple pains held together by iron or other metals. When done well, this can make a typical window look luxurious.

A lattice pattern, for instance, can make a casement window more ornate without creating a fussy aesthetic. Instead, the pattern has a homey, comfortable feel that could belong in practically any kind of house.

Different Types of Casement Windows

Standard casement windows always have hinges built into their sides. Whether they open to the left or right, they rely on properly placed hinges. Similar windows, however, open by lowering the top of the window or lifting the bottom of the window.

If a casement window has hinges at the bottom, then it is considered a “hopper.” If it has hinges at the top, then it is called an “awning window.” Other than the hinge placement, it is nearly impossible to tell the difference between these windows.

Casement windows have been popular for hundreds of years. Today, many people prefer windows that slide. Still, these crank-controlled windows fill a unique niche in modern architecture by adding an extra layer of decoration that can turn a house into a home.

    Casement windows would really fit in our basement and my husband is always trying to convince me to get them but to be honest, I think they’re ugly! This article was great though – I never thought about using decorative glass, that’s a great idea. It would be a happy compromise between what he wants and what I want and I think I’m OK with that 🙂
