Bay Windows

The bay replacement window is a set of 3 or more windows.

A bay window (sometimes called oriels window) is a window space that projects away from the main walls of a building and forms a bay in a room, which can either be square or polygonal in shape. Bay windows are commonly installed at angles of 90, 135 and 150 degrees on the inner corners of the bay. Typically associated with Victorian architecture, bay windows can completely transform both the home’s interior and exterior spaces. They offer great aesthetics that easily become the focal point for any home which clearly explains why bay windows are not just your ordinary windows.

Bay windows are commonly arranged with three panes of glass, one large pane in the middle parallel with the wall, and two smaller angled panes (called flankers) on either side. Flankers are typically angled at 30 and 45 degrees. They are also often configured as double hung or casement windows to allow them to open for ventilation purposes although they can also be permanently closed.

What is special about a bay window is its large pane at the center, which along with the two flankers on both sides, provides a clear and unobstructed view to the outside and the added benefit of some ventilation options. Just like with bow windows, the configuration of bay windows creates a nice architectural feature and at the same time provides extra living space inside the home. Typically, this additional space is designed to create a cozy and comfortable nook ideal for reading, sitting or enjoying the outdoor view.

Bay windows basically come in two main styles. The first style is shaped like a box and protrudes outwards making it suitable for the placement of house plants or ornaments. This design is commonly installed above the kitchen sink or other hard to reach areas to let a good amount of lighting in without compromising the general shape of the house. In other situations, bay windows are designed as an actual component of the floor-to-ceiling polygonal shape intended to create a nook and deviate from the floor plan. Commonly, for this design, bay windows are trapezoidal in shape wherein the narrowest part of the trapezoid projects outwards.

Bay replacement windows will open up a room and let it breathe. Additionally, they have the ability to make the room appear larger than it actually is and invite more natural light inside. By investing in bay windows, you will not only get these benefits, you will also be able to spice up and add a splash of glamour to your home.
