Our Replacement Window Styles Fit Any Home Your new Pella® windows should complement the architectural style of your house and your lifestyle. Browse through these examples of the window options offered or that are available at our Boston showroom. Casement Windows A practical option for those who are looking for easy operation and no reaching – the windows open and close outward with a swift turn of a handle. Awning Replacement Windows 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 enhance the view. Double-Hung Windows Double-hung windows combine a traditional style with flexibile ventilation. Both sashes open - a little or a lot. Single-Hung Windows Single-hung windows have a traditional style and open by sliding up the bottom sash. They are typically less expensive than double-hung windows. Sliding Replacement Windows Sliding windows have a sliding sash that opens horizontally so you won’t have to reach. Specialty Windows We offer additional window options featuring styles and operational types frequently found in first-rate homes around the world. Special Shape Replacement Windows These windows may be used to feature other architectural features in your space, such as a fireplace, or they may 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. Our team can create virtually any design you would like.
