What Is More Expensive Bow or Bay Windows?

Bow Windows

• Bow windows form a series of three, four or five windows placed side by side at a slight angle, creating a curved window. The curve is generally 10 degrees, which gives the window a rounded look. Most bow windows are the same size and can consist of windows that do not open, also referred to as fixed windows; windows that do open, also called vented windows; or a combination of the two.

Bay Windows

• Bay windows are three windows fitted together to create a rounded appearance. The center window in the bay is usually a larger fixed window, while the two outside windows are smaller vented windows. Bow windows are created at either 30- or 45-degree angles -- the larger the angle, the deeper the area in front of the window.

Pricing

• Bow windows are more expensive than bay windows. One reason for the price difference is the total number of windows: Bay windows have three windows, while a bow window can have up to five. Another consideration for price is the hardware needed to make a vented window. Vented windows require a track and locking mechanisms, whereas fixed windows do not.

Considerations

• Choosing between bow and bay windows is a choice of personal preference. Bay windows, because of their steeper angle, allow for room additions such as window seats and an area to display special pieces of furniture, such as a piano. Bow windows make a good focal point and add more light to a room -- plus, they have a deep window sill, making that area ideal for sun-loving houseplants.
