THE STYLE
Casement windows
Side-hinged windows that open outward. A versatile choice for everyday ventilation in homes and selected building applications.
WHY CASEMENT WINDOWS
What they do well.
A tight seal
When locked, the sash is drawn against the frame weatherstripping, which helps keep drafts out in winter.
Easy to reach
A crank handle makes them simple to open over a counter or a deep sill.

INSIDE THE FRAME
Built to insulate.
A 32 mm thermal break separates the inside and outside of the frame, cutting the path heat takes through the aluminum and letting each side carry its own colour.
Replaceable compression seals and interior glazing keep the window serviceable for the long run.

What is a casement window?
A casement window is hinged on one side and opens outward with a crank or lever, like a door. It gives full-height ventilation and seals tightly when closed.
Aluminum or vinyl casement windows?
Vinyl is a cost-effective, low-maintenance choice for most homes. Aluminum offers slimmer frames, larger glass and a wide range of factory colours. We’ll recommend what suits your home and budget.
Where do casement windows work best?
Kitchens, bedrooms and any opening where you want maximum airflow. They also pair well with fixed picture windows in a combined unit.
Can casement windows be used for bedroom egress?
Often yes, because the whole sash opens. Egress depends on the clear opening size required by the building code, so we confirm it when we measure.
