What is the Difference Between Bay and Bow Windows?
Bay windows and bow windows both have similar architectural features that protrude from the wall. And, they have more than one panel tailored together to form a single unit. However, both have a few key distinctions that make them unique. The main difference is architecture. One form of window is angled, while the other has a curved structure.
Here are a few key differences between the two window options.
A bay window generally consists of three windows with a picture window in the center. And on the sides, it has smaller windows. A bow window, on the other hand, comprises four to six windows and curves outside. Each window is of a similar size, thereby creating a gentle curve. This is especially appropriate for a Victorian house but can also be a great addition to a modern house. Because of the size and shape of these windows, you may have to order custom treatments increasing the total cost.
Of the two window styles, bay windows are those that add square footage. You can use the additional interior space for storage or as a window seat. However, they take up quite a bit of outdoor space. This can become a problem if your home is pretty close to the street or sidewalk.
Bow windows generally have a small ledge but add no actual area. So if you don’t have much open space, this is the way to go. But they take more than a bit of wall space, while bow windows never take that much floor space.
Bay windows look nice in modern homes as their angles are shaped. However, they have been around for hundreds of years and can be seen in colonial homes. Bow windows make up some of the newer designs. But, bays are more versatile and are ideal for modern, colonial, and traditional homes. On the other hand, if you live in a historic Victorian house or an upscale home, bow windows will fit right in.
Ventilation is not an option with bow windows. The opening mechanisms can interfere with the architecture. But, bay windows offer better ventilation because they can contain more venting options. They have one large picture window center and two narrow sides down either side. Picture windows will not open since they are formed from a fixed glass pane. However, the side windows are operable. They can either be casement, double-hung, or single hung.
Installing both windows is quite challenging even for a professional. This is because they are much more complicated than a standard window. Due to its larger size and weight, the bow window is more difficult to install. However, both types may present challenges for a DIY installation. The existing window opening will need to be enlarged and expanded to fit the current frame. It’s best to get window installers to do this renovation project.
With a proper installation, both bow and bay windows can increase the resale value of the house. A beautiful and appealing glass window featuring sparkling glass will attract buyers. It has also been proven to increase light. Moreover, it also reduces clutter while ensuring good ventilation inside and outside.
Bay and bow windows allow lots of natural light than flat windows. However, bow windows are perfect for homes that require abundant light. Natural light is said to improve health by preventing seasonal affective syndrome. It also helps increase vitamin D levels.
In contrast, the bay contains only three glass panels. Hence, they give less natural light than a four-wall bow window. As a result, the bay windows don’t get enough sunlight, but they give more privacy.
Large windows give great views of the sky. A bow window gives you a broader panoramic look at your surrounding landscape. However, if you want a clear view of the outdoor area, a bay window is a perfect option. A bow window is better for a larger view offering a more broad view than a bay window.
A bay window extends from the building by at least 2 feet. They may be a poor choice for buildings located closer to road surfaces and curbs. In contrast, bow windows have narrower profiles up to 4 inches. They need only 11 inches for an 8-foot wide window, making them the better choice for places with space constraints.
Energy-efficient windows are vital if you are looking to save money on your energy bills. Unfortunately, the larger surface area of both windows may affect your energy efficiency. But, with an energy-certified star window, you should be able to save on heating and cooling costs.

Compared to your standard windows, both bay and bow windows are expensive. However, a bow window is more expensive when compared to its counterpart due to its large size.

Bow window installations require a new roof and a soffit tie-in to seal the windows against the draft.
