Our Replacement Window Styles Fit Any Home Your Pella® windows should match the architectural style of your house and your lifestyle. Here are some examples of the window options Pella offers or that are available at our Wilmington showroom. Casement Windows A great option for those who desire easy operation and no reaching – they open and close outward with the quick turn of a handle. Awning Awning windows smoothly open and shut with one handle. Bay and Bow Replacement Windows Even with limited wall space, a bay or bow window allows you to have more windows to enhance the view. Double-Hung Replacement Windows Double-hung windows mix a traditional style with ventilation options. Both sashes open - a little or a lot. Single-Hung Windows Single-hung windows are a traditional style and open by raising the bottom sash. They are often less expensive than double-hung windows. Sliding Replacement Windows Sliding windows have a sliding sash that moves horizontally so you won’t have to reach. Specialty Replacement Windows We offer additional window options featuring styles and operational types commonly found in exquisite homes around the world. Special Shape Replacement Windows Use specialty shape windows to highlight other architectural features in your room, like a fireplace, or they can be used alone in spaces where space is tight, such as a stair landing. Custom One-of-a-kind wood windows are designed and built just for your space. Pella can create nearly all designs you bring us.
