Our Replacement Window Styles Fit Any Home Your Pella® windows should match the architectural style of the room and your lifestyle. Here are some examples of the window styles we offer or that are available at our Boise showroom. Casement Windows A great choice for those who are looking for easy operation without reaching – casement windows open and close outward with just the turn of a handle. Awning Replacement Windows Awning windows gently open and shut with one handle. Bay and Bow Even with a smaller wall space, a bay or bow window allows you to have more windows to let you enjoy the view. Double-Hung Double-hung windows mix a traditional style with ventilation flexibility. Both sashes open - a little or a lot. Single-Hung Single-hung windows feature a traditional style and open by lifting 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 Pella offers several 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 feature other architectural features in your room, like a fireplace, or they are also frequently used alone on walls where space is tight, like a stair landing. Custom One-of-a-kind wood windows are designed and built just for your space. We can build virtually any design you would like.
