What Is a Casement Window?

A casement window is hinged on the side and opens outward using a crank handle. Unlike sliding or double-hung windows, casement windows swing open like a door, allowing for full top-to-bottom ventilation.

Casement windows are a popular choice for homeowners who want unobstructed views, maximum airflow, and a tight seal when closed—making them especially energy efficient for homes in the Chicago suburbs.

Why Homeowners CHOOSE CASEMENT Windows…

Benefits of Installing Casement Windows for Your Chicago Home

Superior Ventilation: Hinged on the side and open outward to catch the breeze from any direction.

Energy Efficient: A tight seal along all edges keeps your home comfortable and helps lower utility costs.

Unobstructed Views: Slim frames and wide openings provide a clean, modern aesthetic and maximum natural light.

Easy Operation: Smooth crank handles make them simple to open, even in hard-to-reach places.

Secure Design: Multi-point locking systems offer added safety and peace of mind.
