Our Replacement Window Styles Fit Any Home Your new 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 Wellesley showroom. Casement A practical option for those who are looking for easy operation with no reaching – casement windows open and close outward with a swift turn of a handle. Awning Windows Awning windows gently open and shut with one handle. Bay and Bow Even with limited wall space, a bay or bow window gives you more windows to capture the view. Double-Hung Replacement Windows Double-hung windows combine a traditional style with ventilation flexibility. 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 usually less expensive than double-hung windows. Sliding Replacement Windows Sliding windows have a single sliding sash that moves horizontally so reaching isn’t a problem. Specialty Windows Our Architect Series® line offers extra window options featuring styles and operational types commonly found in fine homes around the world. Special Shape You can use them to feature other architectural features in your room, such as a fireplace, or they may be used alone on walls where space is tight, like a stair landing. Custom These unique wood windows are designed and built just for your home. We can create almost any design you would like.
