Casement Window Types: A Complete Guide

Many people try to save money on their windows and pick picture or sliding pictures, but some of us prefer sophisticated windows like casement windows.

With their superior security and energy efficiency, casement windows make a fine addition to your home. They give you clear views of the beautiful outdoors.

Fortunately, there are many different types of casement windows to choose from.

In this guide, we’ll be going over each casement window type. Afterwards, I hope that you’ll be able to tell me exactly which casement windows you want to add to your home.

Single Frame Casement Windows

First, we have the simplest of them all, the one and only classic single frame casement window.

It’s exactly as the name says. There is a singular frame that you can open and close via one hinge. Basically, it looks like a tall rectangle with a piece of glass in the middle.

Single frame casement windows are common in modern contemporary homes. They are simple and look super clean.

With a single frame, you can decide whether you want your casement window to open in or out. Opening outwards is much more common, but if also intrudes into the exterior of your home. It could block pathways.

Single frame casement windows are perfect for adding in more natural light because they give you clear views of the outdoors. There is also no clear middle, so it’s a super clean look from the outside too.

Unlike picture windows, casement windows offer ventilation and improved air circulation in your home when you open them.

These windows typically open and close via a crank.

Here are some pros for single frame casement windows:

  • Clear view of the outdoors because there is no center bar or grids
  • Better airflow because they can open completely
  • Better energy efficiency due to the airtight seals
  • Better security because it can only be opened from the inside
  • Easy to install because it’s only one frame

Double Casement Windows

Next, we have the double frame casement windows. It’s just like the name suggests. Instead of a single frame… we now have two!

They typically sit side by side and open outwards. You have a big window opening with two sashes.

Like single frame casement windows, you still get amazing airflow and ventilation.

Because casement windows open all the way, you still get an expansive clear view of the outside.

Double frame casement windows are also known as double French casement windows.

These are elegant and can give your home an open feel. These windows typically open and close via a crank.

The pros of double frame casement windows include:

  • Better airflow due to having a large window opening
  • Better lighting with no grids or center bar
  • Clear expansive view of the outside
  • Energy efficient
  • Unique style for your home

Push-Out Casement Windows

Unlike regular casement windows, which open via a crank, push-out casement windows open by pushing them out.

It usually has a handle that you turn or tilt to unlock the window. Then you just push each side out. It opens easily, and there’s less maintenance to keep the crank working well.

These windows have extra security via the handle and the sash locks.

Push-out casement windows are not very popular. They don’t have the classic look of a casement window. They’re much more minimalistic and fit into more modern homes.

However, you still get all of the benefits of a casement window, including:

  • Better airflow
  • Easy cleaning
  • Better security
  • Great view of the outdoors

Push-out windows can be a great way to make your windows more accessible to people who may have difficult operating a crank.

Or maybe you’re sick and tired of having to maintain the crank.

Push-Out French Casement Windows

Push-out French casement windows are a combination of French windows and push-out casement windows.

They have two sashes on either side that open outwards. Instead of a crank, however, they open via a handle that you turn and then push out.

In-Swing Casement Windows

Another type of casement window is the in-swing casement window. Instead of opening via a crank or by pushing out, you swing them in.

They have handles that you can pull on to open up your window.

Unlike previous casement window types, this type doesn’t protrude outwards when open.

If the outside area of your casement window is a walkway or something that blocks something else, these are perfect. They are also easier to reach to open up.

In-swing casement windows are useful for kitchen countertops where you already have to reach over your sink to open them.

You can also have in-swing double French casement windows, where you can swing both sashes inwards.

Which Casement Window Type is Best For You?

When choosing the perfect casement window for your home, there are many factors you need to consider.

The first one is where will the casement window go?

The location of your casement window is important for knowing which way you want the casement window to open.

If the casement window opens to a porch or balcony, perhaps you’ll want to get an in-swing casement window to give you more space on your balcony.

You also don’t want to limit the opening of the windows too much either.

Are you on the first floor or the second floor?

If you’re on the first floor, getting an in-swing window might make more sense too. You don’t want to block any pathways or planters you may have.

If you’re on the second floor or higher, you can open outwards via a crank or via a push-out casement window.

How big of a window opening are you looking to replace?

The size of your window will determine whether you want a single frame or double frame casement window.

So the two main decisions are:

  • Single or double frame?
  • Which way do you want it to open? Crank? Push-out? Swing in?

Once you decide those, you’re ready to go. Now you can move onto the fancy stuff like the frame material, the wood stain, grids or no grids, what kind of glass, etc.

There are so many decisions that go into getting replacement windows.

Talking to a local contractor or window expert could help you greatly.
