Welcome to our latest blog post, where we'll dive into the wonderful world of casement windows!

If you're in the market for new windows or simply curious about the different options available, you've come to the right place. Let's explore!

What Is A Casement Window?

Let's start with the basic knowledge of what a casement window is. Casement windows are those where the window is attached to its frame with hinges on one side, allowing it to open outward or inward instead of sliding like other windows.

They are becoming popular due to their attractive design, low-maintenance needs, and energy efficiency. Their tightly sealed edges keep the drafts out and provide excellent insulation.

Plus, they come in various materials – wood, metal, and plastic – and multiple styles for those of you looking to make a statement. So, no matter what your needs are, you'll find the perfect casement window for your space.

Now, let's move on and explore the different types of casement windows.

Single Frame Casement

These are the most basic casement windows. They are constructed from one pane of glass and open outward, like a door. They are usually hinged on the side and use a crank mechanism to open and close. 

A single frame allows these windows to offer an unobstructed view of the outdoors. Plus, they provide better security as it's hard to pry open them from the outside. They're also relatively inexpensive compared to other types.

Yet one of the downsides of these windows is their size. Due to being crafted from one frame, there are limits on how large they can be.

French Casement (Double Windows)

French casement windows are composed of two frames hinged on either side, connecting at the center. They’re like a double door. 

The plus point of these windows is that they’re available in large sizes. So, people who prefer expansive windows, more sunlight, or a larger view of the outside can opt for this type. Moreover, their two-frame design makes them easy to open and close.

On the downside, these windows cost more than single-frame ones due to the extra frame. Also, due to the presence of two edges, they are more prone to drafts since they don't seal as tightly.

Push-Out Windows

Push-out windows are called so because of their mechanism. They are designed to open outward by pushing them with your hands. Both single casement and French windows can be found with this mechanism.

These windows are great for those who find cranks just too "cranky" to handle. Plus, with their minimal hardware, you get a nice and uncluttered look.

They're also straightforward to clean. Push them in for easy access, and there you go. And yes, they are securely locked at whatever angle you leave them.

However, they do ask for maintenance. To ensure your push-out windows keep performing smoothly, keep an eye on the hinges and hardware. If left unattended, these components can start to become stiff, loose, or rusty. And this will make it hard to open the windows.

In a nutshell, push-out windows are a great way to add convenience and style to your home. They require minimal effort to operate and look good. Just remember to keep up with the maintenance, and your push-out windows will serve you well for many years to come!

Egress Window

Egress windows are one of the most specific types of casement windows.  They are designed and installed primarily for safety reasons. As the name suggests, these windows provide an emergency exit route in case of a fire or other disasters.

For this reason, these windows must meet strict criteria. This includes being large enough for someone to enter or exit through them easily. In most cases, they must be at least 5.7 square feet in size and have a minimum clear opening height of 24 inches.

Egress windows are usually installed in basements but can be placed in any other accessible home area.

Beyond keeping your family safe, installing these windows can have more fun perks. When they're open, you'll be sure to experience a nice breeze and abundant natural light to brighten your house – making it the perfect spot for a summer staycation!

Parts Of A Casement

No matter which style of casement window you choose, there are a few essential parts that each one has in common. Let's take a look at them. 

  • Frame: This is the outermost part of the window that houses all the other parts.
  • Sash: It's the moveable part of the window that holds the glass.
  • Crank handle:It's also known as the operator and allows you to open and close the window.
  • Hinges:These are attached to either side of the sash and connect it to the frame, allowing it to swing open outward or inward.
  • Lock latch:This keeps the window securely shut when closed.
  • Casing:This is a trim around the frame that helps to seal the frame and makes it look neat. 
  • Stays:These are the supports that hold the window open when desired.
  • Screen:This is a metal mesh piece that is usually removable. It is installed outside the window to prevent pests and other debris from entering your home.
  • Weather stripping:This material goes around the perimeter of the frame to help seal it from outdoor elements.
  • Decorative grills: These optional pieces can be added to the outside of your window for extra aesthetic appeal.


These are all of the main parts of casement windows, but there may also be other components depending on the type and style you choose.

Now that you know the different parts and types of casement windows, you're ready to select the perfect one for your home or business. With all the options available, you'll find something that fits your style and budget. Good luck shopping!
