Our Replacement Window Styles Fit Any Home Your Pella® windows should match the architectural style of the room and your lifestyle. Explore our examples of the window types we offer or that are available at our Casper showroom. Casement Windows A great choice for those who need easy operation and no reaching – casement windows open and close outward with a swift turn of a handle. Awning Awning windows easily open and shut with one handle. Bay and Bow Even with a smaller wall space, a bay or bow window gives you more windows to let you enjoy the view. Double-Hung 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 feature a traditional style and open by sliding up the bottom sash. They are typically less expensive than double-hung windows. Sliding Sliding windows have a sliding sash that opens horizontally so there is no reaching involved. Specialty Windows Our Architect Series® line offers several additional window options featuring styles and operational types often found in first-rate homes around the world. Special Shape Use specialty shape windows to feature 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 Replacement Windows These original wood windows are designed and built just for you. Our team can make virtually any design you have in mind.
