Our Replacement Window Styles Fit Any Home Your Pella® windows should go hand in hand with the architectural style of your home and your lifestyle. Explore our examples of the window options we offer or that are available at our Saint Louis showroom. Casement Windows A practical choice for those who are looking for easy operation with no reaching – casement 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 Windows Even with limited wall space, a bay or bow window gives you more windows to capture the view. Double-Hung Double-hung windows bring together a traditional style with flexibile ventilation. Both sashes open - a little or a lot. Single-Hung Single-hung windows feature a traditional style and open by sliding up the bottom sash. They are usually less expensive than double-hung windows. Sliding Sliding windows have a sliding sash that opens horizontally so reaching isn’t a problem. Specialty Our Architect Series® line offers extra window options featuring styles and operational types often found in fine homes around the world. Special Shape Windows Use specialty shape windows to highlight other architectural features in your home, such as a fireplace, or they can be used alone in areas where space is tight, like a stair landing. Custom Replacement Windows One-of-a-kind wood windows are designed and built just for you. We can create virtually any design you bring us.
