Bow Windows

Bow and bay windows are often confused as being the same. Although similar in many ways especially in set-up, both are made up from a series of casement and picture windows, each has interesting and unique features that make them different from one another. Perhaps, the main difference between the two is the angle at which they are installed. The configuration of bow windows consists of four or more window units while a bay window only has three.  Moreover, with bow windows, the individual window units are joined together to form an arc while with bays, they are arranged between 30 and 45 degrees to each other.

Bay-Bow-WindowBow windows first gained popularity in the 1870s. They actually first appeared in the 18thcentury in the United Kingdom, and in the US during the Federal period. Bow windows got the name because of their shape, which is slightly curved like a crescent. Largely because of this design, bow windows are a popular choice when it comes to spicing up the design element of a house or building.

Just like bay windows, they provide extra space inside a room which can be utilized for the placement of ornaments and houseplants. Most people however use the extra area for cushioned window seats creating a cozy and relaxing nook by the window. Another great thing about bow windows is that they invite a significant amount of natural light into the home.

Today, vinyl bow windows remain the most popular although those that are made from fiber glass are not far behind. Bow replacement windows are offered in several varieties. Some come with a curved glass while other models feature straight panels of glass that offer a more circular look than common types of bow windows.

If you are planning to have bow windows installed in your home, it would be nice to go for those that have windows that can be opened from either side. Other great options are models that come with double-paned glass for better insulation. Installing these bow windows can definitely increase the overall energy efficiency of your home.
