Bay and bow windows

A bay window combines three or more windows into one unit with windows at various angles. One popular variation is a bow window where four or more windows are arranged in an arc. 

We make bay windows that include three windows joined together. These bay windows include a picture window at the center with flanking casement or double-hung windows. The advantage of using these types of windows is that the picture window allows for a large expanse of glass while the casement or double-hung windows allow in fresh air. The flanking windows can be at an angle of 30°, 45°, or 90° degrees to the center picture window. Our bay windows project away from the home but don’t reach all the way to the floor. They’re supported by brackets underneath. On the inside, there’s a shelf that’s a favorite perch of cats and an ideal home for potted plants. Find these windows available through our 400 Series and E-Series product lines.

We also offer bow windows through our 400 Series and E-Series product lines. These options include at least four casement windows that are arranged at 10° angles to create an arc.

In addition to our factory-joined bay windows, you will see bay windows created through wall framing. A bay window created through wall framing will extend to the floor, so it adds square footage to your home. When a bay window is created in this way, it’s called a walk-out bay. This style of bay window is most easily created when you’re building a new construction home because it requires that the foundation support the bay. Walk-out bays can be created with windows from any of our product lines. You may consider including joined windows within this type of bay, particularly if it will be very large. For example, we often see joined windows (windows that attach without structural wall support) used for the center of a walk-out bay. The benefit of doing this is that you get an extra-large expanse of glass. And if this is all getting a bit confusing, just remember that your architect and builder can help you land on the perfect bay window for your home.

Due to their drama and beauty, bay windows are typically featured in gathering spaces within the home. They’re especially impactful in a living or dining room, and they create a display case for plants and the like. In rooms that face the street, their distinct look is sure to boost curb appeal, but they can also be a charming addition to a child’s bedroom. They’re hallmarks of certain classic home styles.

A bay window adds so much to a home, including the following: 

• Panoramic views created by windows set at a variety of angles.
• More natural light created by having multiple windows at a variety of angles.
• Extra space created by projecting beyond the walls of the home.
• Added character created through its distinctive look. 

The exact cost of a bay window will depend on many different factors, including the product lines selected. Our factory joined bay and bow windows are available through the E-Series and 400 Series product lines. Of these, the E-Series unit is more expensive. 

Generally speaking, bay windows are more expensive than other types of windows. This is because bay windows are made from multiple windows. Not only does that mean more materials are required, but it also means manufacturing is more complex because the windows are joined together in the factory. Another cost is that of installation. Bay windows are simply more complex and more time-consuming to install. Bow windows can be even more expensive than bay windows for all the same reasons. A bow window will include a minimum of four windows and its installation is even more complex and more time-consuming than what’s required for a bay window.

Good question! A bay is an architectural term that refers to a compartment between vertical framing elements. Bay windows relate to this concept because of the compartment they create by projecting out beyond the home.
