St. Louis Casement Windows

For Superior Window Products, Call Building Envelope Experts!

People love their casement windows, and for good reason—they provide the ultimate combination of airflow, flexibility, and ease of use. Unlike double-hung windows, casement windows are not prone to seizing and becoming extremely difficult to open. They’re incredibly easy to use for almost anyone, since they operate by only a simple hand crank, and they allow you to enjoy a fresh breeze on a beautiful day with little effort. However, older and worn-out casement windows are an extremely likely source of energy leaks, particularly when seals fall apart or sash components begin to degrade and crack.

Why Replace Your Casement Windows?

Just like any other type of window around your home, your casement windows will eventually wear out, and when they do, they’ll become a serious drain on your home’s energy efficiency. Because casement windows have a single pane of glass that swings outward, the entire area around the pane is actually vulnerable to air leaks. Unlike double-hung windows where two sides are constantly in contact with your window’s frame, casement windows are hinged on one side, meaning the connection is generally small.

Over time, when materials start to wear out, casement windows are extremely leak-prone, both around the window and through other areas like the hinges and window sash. Modern casement windows feature not only improved materials for better durability and energy efficiency but typically also feature double-pane technology that helps reduce heat loss through the glass itself. Plus, with maximized glass space and improved crank mechanisms, you’ll enjoy a more beautiful view, whether you want the window open or closed.
