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 options we offer or that are available at our Woburn showroom. Casement Replacement Windows A practical style for those who need easy operation with no reaching – they open and close outward with just the turn of a handle. Awning Awning windows gently open and shut with one handle. Bay and Bow Replacement Windows Despite having little wall space, a bay or bow window will use more windows to enhance the view. Double-Hung Windows Double-hung windows mix a traditional style with ventilation flexibility. Both sashes open - a little or a lot. Single-Hung Single-hung windows are a traditional style and open by lifting the bottom sash. They are usually less expensive than double-hung windows. Sliding Windows Sliding windows have a sliding sash that opens horizontally so you won’t have to reach. Specialty Replacement Windows We offer additional window options featuring styles and operational types frequently found in first-rate homes around the world. Special Shape You can use them to feature other architectural features in your room, like a fireplace, or they are also frequently used alone in spaces where space is tight, such as a stair landing. Custom These original wood windows are designed and built just for you. We can create almost any design you have in mind.
