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.
Simple, reliable operation with a single crank mechanism.
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.
Crank-operated hinges let the window swing fully open, capturing airflow that sliding styles can’t match.
The compression seal presses shut against the frame rather than sliding, cutting energy loss through Colorado’s cold snaps and summer heat.
No center rail means a clean, open sightline — just glass, frame, and the view outside.
A simple crank mechanism makes opening and closing effortless, even for hard-to-reach windows.
