Our Replacement Window Styles Fit Any Home Your new Pella® windows should go hand in hand with the architectural style of your home and your lifestyle. Here are some examples of the window options offered or that are available at our Denver showroom. Casement A good style for those who need easy operation without reaching – they open and close outward with the quick turn of a handle. Awning Windows Awning windows easily open and shut with one handle. Bay and Bow Replacement Windows Even with a smaller wall space, a bay or bow window will use more windows to capture the view. Double-Hung Double-hung windows combine a traditional style with ventilation flexibility. 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 typically less expensive than double-hung windows. Sliding Replacement Windows Sliding windows have one sliding sash that opens horizontally so reaching isn’t a problem. Specialty Replacement Windows We offer extra window options featuring styles and operational types frequently found in first-rate homes around the world. Special Shape These windows may be used to feature other architectural features in your room, like a fireplace, or they can be used alone on walls where space is tight, such as a stair landing. Custom Replacement Windows One-of-a-kind wood windows are designed and built just for your space. Our team can make nearly all designs you have in mind.
