What is a Casement Window?

A casement window is hinged on one side and swings outward like a door, operated by a smooth crank handle. When fully open, it allows maximum airflow across the entire window opening, making it one of the most effective styles for ventilation. The crank mechanism also gives you precise control over how much fresh air enters your home.

Why Choose Casement Windows

See why casement windows are a top choice among Toronto homeowners for performance, comfort, and style.

Maximum Ventilation

Because the entire sash swings open, casement windows provide 100% airflow across the window opening—the highest of any operable window style.

Energy Efficiency

When closed, the window sash presses firmly against the frame’s weatherstripping, creating a high-compression airtight seal that eliminates drafts and lowers utility bills.

Enhanced Security

Equipped with multi-point locking systems, these windows hook into the frame at several spots, making them incredibly difficult to force open from the outside.

Slim Frame Design

Designed without a center rail (meeting rail), the large, single pane of glass offers a clear, panoramic view of the outdoors, perfect for modern architectural styles.

Effortless Operation

The smooth crank-handle mechanism is easy to use for all ages and is ideal for hard-to-reach areas, such as over a kitchen sink or behind a large piece of furniture.

Easy Cleaning

The crank system lets the sash swing inward, giving you full access to both sides of the glass from inside your home — no ladders required, even for upper floors.
