Our Replacement Window Styles Fit Any Home Your new Pella® replacement windows should match the architectural style of your home and your lifestyle. Here are some examples of the window styles offered or that are available at our Haverhill showroom. Casement Windows A practical style for those who desire easy operation and no reaching – the windows open and close outward with a swift turn of a handle. Awning Awning windows easily open and shut with one handle. Bay and Bow Windows Despite having little wall space, a bay or bow window will use more windows to capture the view. Double-Hung Replacement Windows Double-hung windows mix a traditional style with ventilation options. Both sashes open - a little or a lot. Single-Hung Single-hung windows are 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 single sliding sash that moves horizontally so there is no reaching involved. Specialty Replacement Windows We offer extra window options featuring styles and operational types often found in exquisite homes around the world. Special Shape Replacement Windows You can use them to highlight other architectural features in your home, 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 build nearly all designs you bring us.
