Bay & Bow Windows in St. Louis

Expert Installation of Bay Windows and More 

Both bay and bow windows are an extremely popular home feature that adds panoramic views and loads of additional light to any room they are in. However, by placing so many windows in such a small space, they are also vulnerable to air leaks and lost energy. At Building Envelope Experts, we can help you improve your home’s beauty and energy efficiency by replacing your old and outdated windows with state-of-the-art products from some of the industry’s leading manufacturers.

As a part of our holistic approach, Building Envelope Experts carefully analyzes your bay and bow windows and determines how they are impacting the other aspects of your home comfort.

Bay Window Replacements

A “bay window” is a series of three panes of glass that are set at an angle that bows outward. This creates a small amount of extra space in a room, but also provides a panoramic view by pushing a window out from the side of your home. That means more natural light as well as improved visibility—bay windows make it possible and easy to see almost a full 180 degrees around them.

At Building Envelope Experts, we can customize your new bay windows to exactly what you’re looking for. Whether your windows are standard-sized or customized, are solid-paned or double-hung, we offer world-class replacements from name brands like ProVia® and Sunrise Windows & Doors®.

Customized Bow Windows

Whereas bay windows are restricted to three panes that curve around the middle one, bow windows can include any number of panes forming an arc around a central point. In a bow window, the angle from pane to pane can be much shallower, resulting in a much longer but ultimately slimmer extension away from your building envelope.

Just like bay windows, bow windows can come in a variety of shapes and styles. Some panes may be solid whereas others might be double-hung or segmented. Whatever style or look you’re going for, Building Envelope Experts will help you find the right solution and complete your installation to the highest standards of quality!
