Casement, Sliding & Double-Hung—Oh My! A Guide to Popular Window Styles

When it comes time to replace the windows in your home, one of the first decisions you'll need to make is which style of window you prefer. While you could just stick with the type you have now, you could be missing out on additional benefits if you don't even consider changing styles. To ensure you make an informed decision, here's a look at the most popular window styles and where they work best.

Double-Hung Windows

Double-hung windows are very popular. They consist of two window sashes mounted vertically within a single window frame. To open the window, you can either slide the bottom window up or the top window down.

When do these windows work well?

Double-hung windows are a good choice when you have a window against a patio or porch. They don't swing outward like other styles of windows (casement and awning windows, in particular) so people can sit against them and you can put furniture right outside them.

These windows are also a good choice for anyone with arthritis or limited mobility in their hands since you just have to push or pull on a ledge to open them. Since they open wide, they offer great ventilation.

Casement Windows

Casement windows are mounted on hinges on one side. To open the window, you turn a crank, which is usually placed at the bottom of the window frame.

When do these windows work well?

Casement windows are a good choice if you're really trying to maximize your energy efficiency. They lock very tightly, so you don't experience a lot of air leaks. Casement windows work well over a counter or behind furniture since you only have to reach the small crank to open them. They're also a good choice if you have children or pets since it's harder for them to fall through the small side opening than through a large opening in a hung window.

Awning Windows

Awning windows are very similar to casement windows, but the hinges are located along the top rather than to the side. They also open with a little crank.

When do these windows work well?

If you live in an area where it rains often, you may want to opt for awning windows. The way the window swings upwards when it opens protect the actual opening. While you won't want to leave the window open during a huge storm, you can generally leave it open during a gentle shower without worry. 

Like casement windows, awning windows work well over a counter. They are not a great choice against a patio or porch because they open into the outdoor space.

Sliding Windows

Sliding windows are sometimes sold as gliding windows. They consist of two panels mounted side-by-side in a single frame. To open the window, you slide one panel to the side. 

When do these windows work well?

Sliding windows are ideal of you have long rectangle window openings. Their operation is similar to double-hung windows (they slide to the side rather than up and down), but they have a different look because of the side-by-side arrangement. Sliding windows are a popular choice along patios since they don't take up space when you open them. They are a good choice if you have kids who you worry may play with a crank on a casement or awning window, too.
