DESCRIPTION
Casement windows are hinged at the side and open outward, to the left or to the right. They are commonly called crank windows, since they are opened using a cranking mechanism.
You’ve seen them and probably even used them too, as they are the type of window that is hinged on the side or top of a window frame and then cranked out to whatever position you require. They can be opened all the way out to the exterior of your home and be wide open or you can stop cranking at any time to have them open an inch, four inches or whatever you need on the particular day.
Wherever you stop the crank is where they will sit until such times as you crank them back to the closed position. So, yes, they need a crank or a handle to use. You simply unlock the window and then use the handle to get it to the required position.

Another great aspect about casement windows are the fact that they are completely sealed so when they are shut and locked they offer the homeowner low air leakage and also great noise reduction.
Between the window’s main frame and sash, looking from the outside, there is a brush seal. This brush seal is used to keep dirt and dust out and off the sill. Just past the brush seal there are two more seals called bulb seals, they are used to create suction between the sash and the main frame to prevent water and wind from coming into the home.
The best part about casement windows is that they give maximum ventilation and view to your home. Simply open them all the way and presto, you have all the fresh air you can handle. If it gets windy or you have too much air coming in simply crank the window back in until the room is comfortable again.
Casement windows are made up of one or more distinct casements and can be made of wood, vinyl or Aluminum and because they is free of any rails or other distractions running through them it offers clean views all day every day.

I wanted to move away from my garden door as I disliked having the door open inside and near my dining set. I wanted to install a patio door, so I did my research and came across The Window & Door Specialist. After seeing their amazing reviews, I decided to make an appointment. Ali came out, took the measurements, and provided me with a quote. It was something I needed to think about at first, but I eventually contacted him again, and he came back out. I decided to go with their top-of-the-line product, and I am so glad I did! Triple pane. I am absolutely impressed with how this patio door system works and, most importantly, how professionally it was installed by Jack. Ali and Jack are two amazing people who truly go above and beyond to make sure their customers are completely satisfied. From start to finish, I felt that I was dealing with people who genuinely cared about the quality of their work and my experience as a customer.

Casement Windows – FAQ
Casement or awning windows?
Casement windows are hinged on the side and open outward; awning windows are hinged at the top. Casements catch side breezes; awnings let in air even when it rains.
Do casement windows seal well?
Yes. When closed, the sash presses against the frame, which gives a tight seal against wind and drafts.
Casement or slider windows?
Casements seal tighter and open fully. Sliders are simpler and suit wide openings. We help you choose for each room.
Is the estimate free?
Yes. In-home measurement and a written quote are free, with no obligation.
