A Window Style That Changes Both the Interior and Exterior

Unlike a flat window opening, a bay window projects beyond the wall. That projection changes the room inside and gives the exterior a stronger architectural presence, making bay windows a practical design upgrade as well as a window replacement choice.

How a Bay Window Is Built

A typical bay window combines a larger center unit with two narrower side units set at an angle. The exact configuration can vary based on opening width, projection depth, exterior architecture and whether the side windows need to operate.

Popular Rooms for Bay Windows

Bay windows are commonly used where the homeowner wants the window to become part of the room's design rather than simply fill an opening.

Common Bay Window Configurations

Bay window configurations can vary by projection depth, center-window size, side-window angle and whether the side units operate. The right layout depends on the opening, exterior elevation and how much interior depth you want to create.

What to Consider Before Replacing or Adding a Bay Window

Because a bay window projects beyond the wall, there is more to plan than with a standard flat replacement window. The opening, support, exterior finish and interior trim all influence the final result.

Professional Measurement and Installation

Proper installation matters on any window, but it is especially important on a projecting bay assembly because the unit must be supported, sealed and finished correctly. We help homeowners review the configuration before ordering and install the completed assembly for the opening.
