Understanding the various styles of windows

INLAND EMPIRE – When people refer to a “style” of window, they generally mean a description for the kind of operation the window unit has. Some of the most popular styles are double hung, casement, bay, bow, slider, and picture windows.

To gain a better understanding of what windows “do” and the benefits they offer, here’s a fast look at window styles from the experts at Simonton Windows:

Double hung: Both sash (top and bottom) operate independently on a double hung window. This allows keeping the bottom sash closed and the top sash open for ventilation in the home. This is a great style choice for folks with young children or pets at home because it enhances the ability to get fresh air into a room from the top of a window while keeping the bottom sash closed for safety.

Single hung: Just the bottom sash opens upwards on this window and the top sash in inoperable.

Casement: The sashes are hinged on the side and the window cranks open a full 90 degrees for maximum ventilation. This is a good option for older homeowners who don’t wish to strain their backs with the “push and pull” action of a double hung window.

Slider: You can have multiple window panels that slide open on a track with a slider window. There’s also the option of having a fixed stationary panel that doesn’t open combined with a window panel that slides and glides open. Again, this is a great option for older homeowners since the sliding action of the window is easy on the back and shoulders.

Picture: A picture window does not have the capability of opening at all. It’s a fixed unit usually installed to maximize views.

Bay: Bay windows are created by mulling together three windows at either 35 or 45 degree angles. The windows can be a combination of fixed and operable units, or they can all be operable or all be fixed. These focal point windows are oftentimes found in key areas of the home including living rooms, kitchens and master


Bow: Bow windows are more rounded in appearance than a bay window. They are generally created by placing windows at 10 degree angles. Whereas a bay window has three units, a bow window can have three, five, seven or nine separate windows mulled together as desired.

Awning: With a crank-out awning window, the sashes are hinged on top and the window opens out and upwards.

Basement (or Hopper): Similar to an awning window, except that the sashes are hinged at the bottom and the window opens from the top out for ventilation.

Geometrics: These fashionable windows are usually fixed units. They come in geometric shapes, such as an octagon, half-round or rectangle, and are often “paired” on top of operable units to add more light and style to the home. They’re also used in secluded areas of the home, such as bathrooms, hallways and foyers.

Garden: The unique garden window extends the space outwards from the window. Ideal for over a kitchen sink area, this window features functional casement sidelites and a fixed unit in the center. Shelves allow room for placing plants or other items.
