What are bow & bay windows?

Bay windows and bow windows are beautiful and provide elegant arches, angles, and a great big view. Both bay and bow windows have distinct advantages over traditional flat windows. Not only do they provide a larger view, but they also help provide a wonderful source of light to your home. Bow and bay windows are constructed to protrude outwards from your home. They dramatically change both the feel of a room or home and also give the illusion of substatially more space.

Additionally, bow and bay windows are very attractive on the housing market!

What is the difference between a bow and bay window?

Bow and bay windows are very similar, but have key differences:

  • Bay windows often are made up of three windows of varying sizes.
  • Bay windows typically have a large center window flanked by two smaller windows, which are angled from the wall at approximately 30 to 40 degrees and are often double hung to give adequate ventilation.
  • The large center window in a bay window allows for a large, unobstructed view and serves as a way to ventilate your room.
  • Bow windows are comprised of three to six windows that are all equal size.
  • Bow windows can give the space a gradual curved look and feel, whereas the bay design has a sharper angle.
  • Bow windows can offer greater ventilation.
  • Bow windows can vary in construction, including casement windows, double hung windows, or single hung windows.
