Bay Windows
Bay windows are comprised of three windows of varying sizes. The typical bay window will have a large window in the center with a slightly smaller window on either side. The two smaller windows will be angled away from the wall at around 25 to 45 degrees.
The large center window provides a largely unobstructed view of the outside with the two smaller windows being either fixed or vented to allow cooling air into the home.
Bow Windows
A bow window is made up of between three to six equally sized windows. The windows will extend outside the home similar to bay windows but instead of sharply angled sides, the entire bow window forms an arched shape.
Bow windows extend the view and make a wide view that looks great in a living room, bedroom or elsewhere in the home.
