What Are Casement Windows?

Unlike a more traditional window like a double-hung, casement windows are hinged along one side, opening like a door to either the left or right. Casements open using a crank system and can provide an uninterrupted view of the outdoor surroundings, along with excellent ventilation. The streamlined, clean design of casement windows reinforces these attributes in modern houses. For traditional homes, a casement window can easily blend in with more ornate architecture — or add a contemporary element to the home’s design.

casement window installationAt Zen Windows Denver, we offer casement windows in a variety of sizes and configurations, such as square, rectangular, thin vertical, or thin horizontal rectangle. We can order and install your casement windows as single-lite fixed (does not open and is sometimes referred to as a casement picture window) or vented (can be opened), two-lite horizontal, three-lite with fixed center lite and vented sidelites, and more.

Casement window screens go on the inside of the window, and screens can be coordinated with the interior frame to blend with the window. Keep in mind that casement windows open outward, and outside clearance is needed so that they don’t interfere with a narrow walkway, for example. Let us know what you need or envision, and we’ll provide a free estimate that you can rely on. Then, we’ll take precise, professional measurements at your home and complete a flawless installation.

There is also another form of casement windows — French casement windows, which are divided into two sections and then open outward like French doors.

Our Casement Windows Are Made for High Altitude

High elevations in the Denver area have led to unique requirements for our windows. As you ascend higher, the air pressure decreases; it becomes less dense. This makes it harder to maintain a strong seal on the window. It also affects the way the gas between the panes expands and contracts with changing temperatures.

Zen Windows Denver glass professionals understand what special requirements should be met for high-altitude casement windows:

  • Argon or krypton gas infills keep heat inside your home
  • Low-E coating for the summer heat
  • Multiple panes separated by small air gaps
  • Non-metallic spacers
  • Superior quality frame material

Some of the frequently asked questions we receive about our high-altitude casement windows include:

Are casement windows secure?

With other windows, once you break the glass, it’s easy to reach inside and unlock. Casement windows are difficult to break into.

Can I install a casement window to meet egress requirements?

Yes. As an egress, casement windows have hinges on the side to swing in or out. They are well-suited for smaller basements.

Which is better, push-out or crank-out casements?

It’s up to you. With crank-outs, you turn the crank repeatedly until you reach the desired opening. Push-outs are just that; they require one gentle push, so they’re easier to open. Both window types offer excellent durability and energy efficiency.

  • French/double – French/doube casement windows cost slightly more but require less maintenance. They offer controlled ventilation and unobstructed view.
