Casement Windows

Casement windows from Pella of Gaithersburg open and close easily with a simple handle turn. When you aren’t opening or closing your window with the handle, it collapses away seamlessly so it doesn’t get in the way of roomside blinds. Our casement windows come with some of the most highly regarded operating arms and hinges that avoid rust and corrosion, offering years of reliable operation. Plus, because of how easy they are to operate, they are a good choice for tough-to-reach windows—like those over the kitchen sink.

Like every window from Pella of Gaithersburg, we have a number of possibilities for casement windows that are ENERGY STAR® certified.
