Windows can crank, lift, glide, tilt and turn, move up, down and sideways. For homeowners who need to replace windows in their home, it can seem that options for the look and functionality to replace your old windows are endless. The type of product you choose and how it operates will help you determine the ideal function and look of the windows for your project, so it is important to understand terminology your contractor or building professional might use to describe the options available to you.
Before you begin exploring materials, colors and hardware options, get familiar with five of the most popular window types, what they look like, and how they function.
Double Hung Window
The most popular type of window, the double hung, has previously been associated with more traditional homes, but is making a resurgence in transitional and even modern projects. Two sections of framed glass offer ventilation by sliding bottom up and top down.
This window is hinged on the side, and swings inward or outward like a door, letting air flow freely. You might hear the term “crank-out casement,” which refers to the motion of the hardware when you’re opening and closing the window.
Designed specifically for horizontal operation, gliders have glass-framed panels that slide open on tracks, meaning no lifting is involved.
This type of window is hinged on top and swings outward, so you can leave it open when it rains. Awnings are often placed higher in a home for added privacy and natural light.
Bay and Bow Windows
Bays feature a fixed center window, with venting windows angled on the sides. Bows are made up of a series of windows connected in a gentle curve.
