Casement Windows

Casement windows from Pella of Portsmouth open and close smoothly with the turn of a handle. When you aren’t using the handle, it collapses away nicely so it won’t get in the way of your house’s blinds. Our casement windows feature high-quality operating arms and hinges that avoid rust and corrosion, ensuring years of reliable operation. Also, because of how easy they are to open, they are a good choice for difficult-to-reach windows—like windows over your kitchen sink.

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