When selecting replacement windows, think about your choices on a room-by-room basis. You can’t make an informed decision without exploring the individual traits of each one.

Popular Window Styles

In today’s post, Renewal by Andersen® of Western NY explains how the popular types of unit operate and when to use them:


Also known as the window of America, double hung windows are ubiquitous. They’re the quintessential elements of practically every old-world architectural style because their design doesn’t restrict window size.

Made of two staggered sashes, they move up and down, sliding past each other. Because of the way they operate, they match the aesthetic of homes with traditional roof types, especially the gable. This is apt for designs that require glass units to be set one by one, rather than grouping them together.


Sliding windows operate exactly like double hung units, except they move sideways. In window installation, they’re a favorite choice for shorter walls. In turn, sliding units are generally wide and create an illusion of space.

Because both of their sashes are easy to reach, you can afford to set them near the top portion of the wall. As a result, you can have a greater solid area between the bottom of the window and the floor, which is a natural spot for placing furniture.


Comprising only one sash, casement units swing out and provide the entire aperture available for ventilation and egress. They’re essentially a miniature version of French doors, especially when embellished with grilles. Unlike the double hung, the casement makes the best flanker unit for bay windows, particularly when situated in tricky places, like kitchen sinks.

Casement windows don’t just regulate the airflow extremely well, but they also provide the best insulator out of all operating units. On closing, their single sash presses against the frame to create a weathertight seal for maximum energy efficiency.
