The Beauty of Bow & Bay Windows
Although bow and bay windows are often thought of as the same thing, they have slight differences. Bay windows are typically comprised of just three windows. Often the center window doesn’t open and is a solid pane of glass, while the two side windows may or may not open. The center window can be the same size or larger than the side windows. You may notice that the angles of the three windows are greater in a bay window than bow, making a bay window the perfect choice for a window seat or indoor garden.
A bow window has four or five windows, all of which typically open. It has a gently arched shape and is most often comprised of casement windows or double-hung windows. The benefit of both is that they add more space and light to a home than a straight window wall. You may even feel that the room is bigger when you add bay or bow windows.
Bow & Bay Windows from Renewal by Andersen
If you’re looking to add some architectural interest to your home or make a room feel bigger, consider changing the space by adding a bow or bay window. The change can be quite dramatic without the cost of a huge renovation. When you work with a Renewal by Andersen consultant, he or she can help you decide which option is best for your home, space and budget.
Of course, if you already have bay or bow windows and want replacement windows, we can help with that too. They are available in the same great interior and exterior options as our other replacement window products. Although most people choose no grid in the center panel of the bay window, we do offer four grille grid options. All our replacement windows are energy efficient and low maintenance. In fact, you will find when you replace your current windows of any style with our Low E-4™ double pane windows that your room will be more comfortable all year.
Bow and bay windows are a great way to add more light, space and architectural style to your home.
