Our Replacement Window Styles Fit Any Home Your Pella® windows should match the architectural style of the room and your lifestyle. Browse through these examples of the window styles offered or that are available at our Long Island showroom. Casement Windows A good option for those who desire easy operation with no reaching – casement windows open and close outward with just the turn of a handle. Awning Awning windows smoothly open and shut with one handle. Bay and Bow Replacement Windows Even with a smaller wall space, a bay or bow window gives you more windows to enhance the view. Double-Hung Replacement Windows Double-hung windows combine a traditional style with ventilation options. Both sashes open - a little or a lot. Single-Hung Windows Single-hung windows feature a traditional style and open by raising the bottom sash. They are typically less expensive than double-hung windows. Sliding Windows Sliding windows have one sliding sash that moves horizontally so reaching isn’t a problem. Specialty Our Architect Series® line offers extra window options featuring styles and operational types frequently found in first-rate homes around the world. Special Shape Replacement Windows Use specialty shape windows to feature other architectural features in your room, such as a fireplace, or they are also frequently used alone in areas where space is tight, like a stair landing. Custom One-of-a-kind wood windows are designed and built just for your space. Pella can make nearly all designs you have in mind.
