Casement Windows

Casement windows from Pella of Westerly open and close smoothly with the turn of a handle. When you aren’t opening or closing your window with the handle, it folds away seamlessly so it doesn’t get in the way of roomside blinds. Our casement windows feature top-notch operating arms and hinges that avoid rust and corrosion, offering years of trusty operation. Plus, because of how easy they are to use, they are a good choice for difficult-to-reach windows—like windows over your kitchen sink.

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