Casement Windows

If you’re looking for a modern twist on a classic window design, you can’t beat the casement windows of Wheaton Door & Window Company. By means of an easy-to-operate hand crank, our casement windows swing outward to open—allowing fresh air to circulate in and out through the full length of the window sash. Compared to sliding or double hung windows, casement windows offer more airflow for an equivalent amount of wall space.

Beyond increased ventilation and convenience, casement windows from Wheaton Door & Window are designed to deliver the best the industry has to offer. With innovative features like low-e glass and warm edge spacers, our casement windows boost your home’s energy efficiency all year long. And because each window can be customized to your size, color, and glass preferences, you’re sure to get a look you’ll love!
