Bay Windows

Bay windows are made up of a combination of 3 windows, typically with a picture window in the center and two venting side windows. These venting windows can be casement windows or single hung windows. That being said bay windows don’t necessarily need to feature a fixed window in the middle and vents on the sides, although they usually do. With Gienow’s custom window team, we could design you a bay window with fixed (or picture) windows everywhere, or put an awning in the middle if the bay is small enough. The possibilities are endless.

What is the difference between a bay and a bow window?

You will often hear industry experts refer to all protruding bay or bow window styles as ‘bay windows’ however, this is not entirely true. In fact, the term ‘bay windows’ refers to a combination of three different windows, where as a standard ‘bow window’ can be made up of a combination of 5 individual windows. 

What is a bay window?

By comparison to a standard picture window, bay windows can make a room appear much larger, offer extra space (like a lovely reading nook), and let in more natural light. 

Usually projecting from a wall at 30 or 45 degrees angle, this window style can use any combination of picture, casement, or hung windows. 

What are the styles of bay windows?

Bay windows come in two styles: bench styles and floor models. 

Bench style bay windows feature a head at the top and a seat at the bottom of the bay window. Bench bays are great in kitchens, where they can provide extra counter space. Larger bench bays can be used in living rooms or bedrooms to provide a sitting area or extra shelf space.

Floor model bays allow provide extra living space in a room, as the project out from the home’s main walls.
