Our Replacement Window Styles Fit Any Home Your new Pella® replacement windows should match the architectural style of your home and your lifestyle. Explore our examples of the window options Pella offers or that are available at our Calgary showroom. Casement Replacement Windows A practical style for those who need easy operation with no reaching – casement windows open and close outward with the quick turn of a handle. Awning Replacement Windows Awning windows smoothly open and shut with one handle. Bay and Bow Replacement Windows Even with limited wall space, a bay or bow window allows you to have 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 Windows Single-hung windows feature a traditional style and open by raising the bottom sash. They are usually less expensive than double-hung windows. Sliding Windows Sliding windows have a single sliding sash that opens horizontally so reaching isn’t a problem. Specialty 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 highlight other architectural features in your space, such as a fireplace, or they can be used alone on walls where space is tight, like a stair landing. Custom Windows These original wood windows are designed and built just for your home. Pella can make almost any design you bring us.
