Casement Windows: Advantages and Disadvantages

Ah casement windows. They offer better views and air circulation than your typical double-hung windows. They also look perfect in a bay window too.

Casement windows are a popular choice for window replacements because they have so many benefits. However, like all fine things in life, there are also disadvantages of casement windows.

Today, we’ll be discussing the advantages and disadvantages of casement windows so that you’ll have a complete view of the picture before deciding to get casement windows for your new window replacement.

The Basics on Casement Windows

What are casement windows? They are windows that open outward with a hinge on one side. It’s like how a door opens, but instead of a door, you’re opening a window frame.

There are many types of casement windows to pick from, such as ones that have one frame, two frames, and ones that swing inward versus outward.

Advantages of Casement Windows

Now that you know what casement windows are, let’s look at the various advantages of having them. You might already know some of these because you’ve been looking into getting casement windows.

In case you need some more reassurance, let’s look at all the wonderful aspects of casement windows. There are quite a few of them!

Casement Windows Look Beautiful

First off, we have appearance. Windows are not just a functional accessory for your home. No, they offer real aesthetic value and increase your home’s curb appeal.

If you’re going to be spending more on casement windows, how they look matters.

Casement windows come in various sizes, designs, and more. You can customize them to your liking. Some different examples are double French casement windows versus a single frame.

There are a variety of casement window types, so it’s easy to find one that fits your needs for your home.

It’s as if you’re living in another country and enjoying the slight breeze that flows through your window.

Sure, some might say casement windows are old-fashioned. Others will say that they’re classical and tasteful instead.

It depends on personal preference, but having the option to choose casement windows rather than the typical double-hung window is a great benefit. More options is definitely a bonus when it comes to the window world.

Opening Casement Windows is Easy

Next up in terms of advantages is the functionality of casement windows.

Unlike double-hung or single-hung windows, casement windows can open up all the way. The entire window opening gets air instead of just small gaps here and there.

Air circulation helps with preventing condensation inside of your windows and your home.

Casement windows are also easier to open from difficult areas such as above kitchen windows or high windows.

That’s because you can use a crank to open up casement windows instead of pushing with your arms.

As someone who is quite short, I can’t use the top part of double-hung windows. I can barely even reach the bottom sash in the window next to the kitchen sink to push it up.

In that case, a casement window would make opening it up much easier.

There are also options without cranks. There it is again, that word. OPTIONS.

With casement windows, there are swing-in or push-out methods too. All you have to do is turn and tilt the handle to open it up. It’s that simple.

Casement Windows Gives You Good Ventilation

Good ventilation makes your home’s air better. You get fresh air at all times rather than stale air that smells funky.

Also, it reduces dust and moisture in your home too. What a win.

With casement windows, you can open them all the way. That means you get 100% air flow with these windows.

Sliding windows or sash windows, in comparison, can only open about 50% of the way instead of 100%.

Casement Windows Have Better Security

Security is always something to think about when getting new windows. If your home looks like the windows are easy to break into, it’ll become more of a target for bad actors.

Fear no more. Casement windows are also impossible to open up from the outside.

They have locks that are on the inside that can only be opened from the inside.

Of course, it’s still possible to break the glass itself and break in. But that can happen to any window.

If you want the best security, try using window sensors and alarm systems to discourage any burglars from even trying to break into your home.

Casement Windows Have Better Energy Efficiency

Better energy efficiency can lead to lower energy bills. It also makes it easier for your home to maintain the temperature that you want to have. Like if you want to keep your home at 75 degrees in the summer time, better energy efficiency will decrease the temperature swing in your home.

Of course, this includes using extra window features such as double-glazing, argon gas, and low E coats too.

Compared to windows that can slide such as sliding windows or sash windows, casement windows have completely airtight seals when they are closed.

They use a compression seal that create an airtight space between the window sash and frame.

Because of this seal, you don’t get any air leaks or drafts inside of your home.

Disadvantages of Casement Windows

Okay, we’ve looked at all the good parts about casement windows. But what about the not so good?

Lucky for us, there’s really only a few disadvantages of casement windows.

Casement Windows Need More Maintenance

The first disadvantage is that casement windows need more maintenance.

Why? Well, if you have casement windows that open via a crank, you need to clean it and lube it often.

If not, over time, the crank won’t rotate as good. That means you’ll have a harder time opening up your beautiful window to allow in good airflow.

Cleaning the glass of casement windows is easy though. Because they open up all the way, you can clean them by just reaching out. If your windows are on the first story, it’s even easier.

Casement Windows Are More Expensive

Probably, the biggest downside of casement windows is the cost. It’s much more expensive than a sliding window and sash windows.

Casement windows are more difficult to install, which comes with more labor costs. They also have more parts, such as the crank and the airtight seal too.

However, casement windows have better energy efficiency, so maybe the extra cost will be made up in the long run.

Casement Windows Take Up More Exterior Space

If your casement window is on the first story, they can block a walkway or something when you open them because they open outwards.

Unlike sliding windows or sash windows that just slide, casement windows take up a lot more space.

Casement Windows Can’t Have Screens

If you live in an area with lots of bugs or pollen, you don’t want those things entering your home when your windows are open.

Unfortunately, casement windows can’t have screens installed into them. They open outwards, which would interfere with any screen if you had them.

Casement Windows Can’t Have Window AC Units

If you live in an area that’s hot and you use window AC units, it won’t be a good match with casement windows.

Air conditioners work with windows that slide up and down or side to side. With casement windows, there’s no way to secure the AC unit to the window.

In summary, here are the advantages and disadvantages of casement windows.

Why Choose Casement Windows

  • Homes in windy areas: Casement windows are better for windy areas because they are more secure. Casement windows have a compression seal, offering better energy efficiency.
  • Homes in extreme weather: Casement windows have better energy efficiency for when you’re running your heater or air conditioning more.

They’re also good if you like the aesthetic and open airflow. Casement windows are PERFECT for above the kitchen sink.
