Bow Windows

Educating yourself about windows? There is a good chance your head is full of terms, styles, designs, and features. Well, might as well add one more to your collection of ideas. Take a few minutes to learn a bit more about bow windows.

Bow windows are a derivative of the bay window. Bay windows consist of three or more windows joined together that project outwards from a building. Normally, there is one main window in the center and the two side windows are at a 30° or 45° angle, connecting the main window to the building. A bow window differs from the bay window in that it consists of at least four sashes and sometimes more. The shape still projects outwards in a rounded pattern.

Bow Window Options

A bow window works well in larger locations and can be used to bring a spacious elegance to a room. The graceful curvature of the window brings a defining class to the exterior of the building as well.

Though it is more of a custom feature, you still have many options as to the type of windows you want incorporated into the bow. You can opt for fixed frames for an unobstructed view, or mix it up with windows that open on the sides and a fixed-frame in the front. Casement windows work well, as do double-hung, just to name a few.

As these images represent, you can create many beautiful designs with bow windows. Many manufacturers produce them, and in many cases they come in kits to be assembled.


A bow window can be quite an attractive focal point on your home. It creates an alluring and spacious feel to an interior room, while providing design to the exterior. Even though they come in ready-to-assemble kits, installation is no easy process. To ensure your windows are properly and skillfully installed, only request estimates from prescreened window installers in your area.

When it comes to adding style and making creative use of space, the bay window is a superhero.  With bow windows, you can squeeze a breakfast nook into a small kitchen, make a beautiful garden a room’s best feature, create a comfy window seat for curling up with a good book, and any other cozy design imaginable.

Bow windows blur the lines between inside and out, letting in extra light and added living space. Read on to get the low-down on bow windows.
