There are three types of casement windows. Here they are:
Single Frame Casement Windows
This is the most basic type of casement window. As the name suggests, it only has one window frame. But it can have one or two casements.
Additionally, these windows can open inward or outward depending on how the window is mounted on the wall.
French Casement Windows
Typically, this type of casement window has two windows hinged on each side of the window frame, and they both meet at the center. These windows are reminiscent of French doors.
You can open them both outward for an unobstructed view of the outdoors or choose to swing out one casement giving you control of the ventilation.

What Are The Pros And Cons Of Casement Windows?
There are different market window types, each with its own set of strengths and weaknesses. Here's what you can expect when you choose casement windows for your home.
Casement windows are easy to open. Just turn the crank to unlock it from its position and push it away from you.
They are recommended for those window openings in the hard-to-reach areas of your house, such as above the countertops and kitchen sink.
They open to the sides and from top to bottom, allowing more fresh air to enter your room. This also gives you a complete view of your outdoor area.
These windows are also more energy efficient than other window types that don't open all the way. As they allow more air to enter or circulate, your home is made cooler, reducing your cooling costs.
When closed, they form an airtight seal with the window frame so that no air can get in or out of the house. You can also add weather stripping along its perimeter to improve insulation.
Casement windows are also versatile. They can be made of different materials and come in various colors, so you can use them as part of a larger window installation. They'll work well with bay or bow windows.

Generally, when casement windows are open, they protrude on the exterior portion of your house. They can cause accidents for people passing by who don't notice them.
They can also get damaged when there are heavy winds since they don't have much support other than the hinges on the side.
However, casement windows are also on the pricier side. Their frame and casement need to be made of stronger materials and have to use more hardware to support their weight.
You can't afford to choose low-quality materials as this would affect the performance and lifespan of your window. These windows also come in limited sizes. They can't be too wide since they swing outward.
You also need to be mindful of the maintenance of their hardware. They are prone to wear and tear and rusting since they are exposed to the elements.
Once the hardware deteriorates, the performance and amount of security will suffer.
You won't be able to install a window air conditioner on a casement window if you have plans to put one. You'll have too much open space, and it won't be able to provide adequate support to the AC unit.
These are the main benefits and drawbacks of using casement windows. Moreover, it's good to know these things so that you can assess if these windows fit your preference and need.
