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 styles we offer or that are available at our San Antonio showroom. Casement A great 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 Replacement Windows Awning windows gently open and shut with one handle. Bay and Bow Replacement Windows Even with a smaller wall space, a bay or bow window gives you more windows to let you enjoy the view. Double-Hung Replacement Windows Double-hung windows bring together a traditional style with flexibile ventilation. Both sashes open - a little or a lot. Single-Hung Windows Single-hung windows are a traditional style and open by sliding up the bottom sash. They are often less expensive than double-hung windows. Sliding Windows Sliding windows have a single sliding sash that moves horizontally so there is no reaching involved. Specialty Replacement Windows Our Architect Series® line offers extra window options featuring styles and operational types frequently found in first-rate homes around the world. Special Shape Replacement Windows Use specialty shape windows to bring out other architectural features in your room, like a fireplace, or they may be used alone in areas where space is tight, like a stair landing. Custom Replacement Windows These original wood windows are designed and built just for your home. Pella can build virtually any design you bring us.
