What is a Bay Window?
The broad definition of a bay window is a window that protrudes from the exterior wall of a building. A bay window is often comprised of three windows, but more windows are certainly an option. Most often you’ll see a bay window made of three windows that meet at a 45-degree angle. The left and right windows are usually double-hung or casement windows, whereas the center window is stationary.
What is a 90 Degree Box Bay Window?
Much like a typical bay window, a box bay window also protrudes from the exterior of the home. However, rather than windows meeting at 45 degree angles, they meet at a 90 degree angle. This gives the windows a box-like look (as you can see in the image above).
Note: If the top of your box bay window is also made of glass, it’s considered a garden bay window or sometimes a greenhouse window.
Benefits of Bay Windows
It’s indisputable that a bay window can add great interest to a home’s exterior. These window styles can be found on a wide-array of home styles ranging from Colonial, Victorian and contemporary.
Extra Living Space
Bay windows make for great reading nooks, dining areas or added seating areas.
All that extra glass at multiple angles ensures that a room with a bay window will be awash with natural light for much of the day.
The Downsides of Bay Windows
More Prone to Leaks and Sagging
For this type of window installation, you don’t want to skimp on quality. Lower-quality box windows have a habit of sagging and with all of the corners and connection points, leaks (both air and water) are more likely.
Because of the increased glass surface area, you can expect additional heat loss, resulting in a higher heating bill. Add to that, that many box bay windows use single-pane glass, as it’s difficult to join double-pane windows at 90-degree angles.
Tough to Find Window Treatments
While many homeowners like to leave their bay windows unencumbered by drapes, others want to install curtains for added privacy. Because these windows aren’t typical, it’s hard to find window treatments that aren’t custom made.
