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. Browse through these examples of the window options we offer or that are available at our Birmingham showroom. Casement Replacement Windows A practical style for those who are looking for easy operation and no reaching – casement windows open and close outward with just the turn of a handle. Awning Awning windows smoothly open and shut with one handle. Bay and Bow 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 combine a traditional style with flexibile ventilation. Both sashes open - a little or a lot. Single-Hung Replacement 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 Sliding windows have a sliding sash that moves horizontally so you won’t have to reach. Specialty Pella offers additional window options featuring styles and operational types frequently found in fine homes around the world. Special Shape Windows These windows may be used to highlight other architectural features in your space, such as a fireplace, or they may be used alone in areas where space is tight, like a stair landing. Custom These original wood windows are designed and built just for your space. We can build almost any design you would like.
