Our Replacement Window Styles Fit Any Home Your Pella® windows should complement the architectural style of your house and your lifestyle. Explore our examples of the window types we offer or that are available at our Springfield showroom. Casement Windows A practical option for those who are looking for easy operation and no reaching – casement windows open and close outward with the quick turn of a handle. Awning Windows Awning windows smoothly 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 enhance the view. Double-Hung Double-hung windows combine a traditional style with ventilation flexibility. Both sashes open - a little or a lot. Single-Hung 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 a sliding sash that moves horizontally so there is no reaching involved. Specialty Replacement Windows Our Architect Series® line offers extra window options featuring styles and operational types commonly found in first-rate 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 are also frequently used alone on walls where space is tight, like a stair landing. Custom Windows These unique wood windows are designed and built just for your home. Pella can make nearly all designs you bring us.
