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 types we offer or that are available at our Des Moines showroom. Casement Replacement Windows A good choice for those who are looking for easy operation with no reaching – casement windows open and close outward with just the turn of a handle. Awning Windows Awning windows easily open and shut with one handle. Bay and Bow Windows Despite having little wall space, a bay or bow window allows you to have more windows to capture the view. Double-Hung Double-hung windows mix a traditional style with flexibile ventilation. Both sashes open - a little or a lot. Single-Hung Single-hung windows have a traditional style and open by raising 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 Pella offers additional window options featuring styles and operational types often found in fine homes around the world. Special Shape Windows Use specialty shape windows to highlight other architectural features in your home, like a fireplace, or they are also frequently used alone in spaces where space is tight, like a stair landing. Custom Windows These original wood windows are designed and built just for your space. Our team can make virtually any design you would like.
