Casement Windows

Casement windows from Pella of Lewes open and close easily with the turn of a handle. When you aren’t utilizing the handle, it folds away neatly so it doesn’t get in the way of your house’s blinds. Our casement windows have high-quality operating arms and hinges that avoid rust and corrosion, providing years of dependable operation. Also, because of how easy they are to use, they are a great choice for difficult-to-reach windows—like the window above your kitchen sink.

Like all windows from Pella of Lewes, we have options for casement windows that are ENERGY STAR® certified.
