Bay & Bow Windows FAQs

What are bay and bow windows?

Bay and bow windows add classic style to any home. These styles protrude from the exterior wall of your home, creating a 3-D arc effect on the outside and opening your home up on the inside. Bay windows have 3 glass panels while bow windows may have 4-6.

What is the difference between bay windows and bow windows?

The main difference is the size and number of window panes in the configuration.

Bay windows feature either a three-pane or box design, typically with one “picture window” in the center and a smaller window pane on either side.

Bow windows are a similar structure but are made of four to six panes of angled glass in the same size.

Each bay and bow window is custom-made to perfectly fit the open space in your home and give it a one-of-a-kind look. Their dimensionality creates a dramatic new look for your interior, perfect for a reading area or breakfast nook.

What are the benefits of bow and bay windows?

Besides bringing natural light into your home, bay and bow windows can boast these benefits:

  • Incredibly strong with a slimline design

Window World was amazing! Their prices can’t be beat, and all the way from the sales rep to the install had no issues! I was extremely impressed by the installs promptness, cleanliness as well as consistently working through the install! The weather was a bit cold but the 3 men who were on the install team worked very well together and there wasn’t any debris or mess left behind!
