Pella Platinum Certified Contractor
Casement windows built for Front Range weather.
Casement windows hinge on the side and open outward with a crank, creating a full, unobstructed opening for ventilation. Because they seal by pressing shut against the frame rather than sliding, they typically outperform sliding styles on airtightness — meaning less energy loss during Colorado’s winter cold snaps and summer heat.
- Strong ventilation control
- Compression seal efficiency
- Unobstructed views

Built for ventilation, views & efficiency.
Casement windows hinge on the side and open outward with a crank, creating a full, unobstructed opening for ventilation — with a compression seal that outperforms sliding styles on airtightness.
Strong ventilation control
Crank-operated hinges let the window swing fully open, capturing airflow that sliding styles can’t match.
Energy efficiency
The compression seal presses shut against the frame rather than sliding, cutting energy loss through Colorado’s cold snaps and summer heat.
Unobstructed views
No center rail means a clean, open sightline — just glass, frame, and the view outside.
Easy operation
A simple crank mechanism makes opening and closing effortless, even for hard-to-reach windows.
