Our Replacement Window Styles Fit Any Home Your Pella® windows should go hand in hand with the architectural style of your house and your lifestyle. Here are some examples of the window options we offer or that are available at our Washington DC showroom. Casement Replacement Windows A good style for those who are looking for easy operation and no reaching – the windows open and close outward with the quick turn of a handle. Awning Awning windows easily open and shut with one handle. Bay and Bow Windows Even with limited wall space, a bay or bow window allows you to have more windows to let you enjoy the view. Double-Hung Replacement Windows Double-hung windows mix a traditional style with ventilation flexibility. Both sashes open - a little or a lot. Single-Hung Replacement Windows Single-hung windows feature a traditional style and open by sliding up the bottom sash. They are often less expensive than double-hung windows. Sliding Sliding windows have a single sliding sash that moves horizontally so reaching isn’t a problem. Specialty Windows We offer extra window options featuring styles and operational types frequently found in exquisite homes around the world. Special Shape Windows Use specialty shape windows to highlight other architectural features in your room, such as a fireplace, or they are also frequently used alone in areas where space is tight, such as a stair landing. Custom These unique wood windows are designed and built just for your space. We can build almost any design you would like.
