Bay Windows vs. Bow Windows: Which Option Fits Your Home Best?

Both bay windows and bow windows add depth to a room by pushing past the plane of the wall, but they do not do the same job in exactly the same way.

What Sets Bay Windows And Bow Windows Apart?

The easiest way to tell them apart is by how they are built. Most bay windows are made from three panes or units, arranged so the window projects in a more geometric, boxy profile. This creates a crisp, angular profile that stands out on both the inside and the outside.

A bow window uses four, five, or even six panels arranged in a gentle curve. It creates a flowing look that can soften a facade with lots of straight lines.

Choosing Based On Style, Climate, And Use
