Our Replacement Window Styles Fit Any Home Your Pella® windows should go hand in hand with the architectural style of the room and your lifestyle. Explore our examples of the window options offered or that are available at our Gaithersburg showroom. Casement A practical choice for those who are looking for easy operation without reaching – the windows open and close outward with the quick turn of a handle. Awning Awning windows gently open and shut with one handle. Bay and Bow Despite having little wall space, a bay or bow window allows you to have more windows to enhance the view. Double-Hung Replacement Windows Double-hung windows bring together a traditional style with flexibile ventilation. Both sashes open - a little or a lot. Single-Hung Windows Single-hung windows are a traditional style and open by lifting the bottom sash. They are often less expensive than double-hung windows. Sliding Replacement Windows Sliding windows have a sliding sash that opens horizontally so there is no reaching involved. Specialty Replacement Windows Pella offers several additional window options featuring styles and operational types commonly found in fine homes around the world. Special Shape Windows Use specialty shape windows to feature other architectural features in your home, such as a fireplace, or they can be used alone in spaces where space is tight, such as a stair landing. Custom Windows One-of-a-kind wood windows are designed and built just for you. We can build nearly all designs you would like.
