What is a Casement Window?

A casement window is a kind of window attached to its frame by several hinges at the side.

The Advantages of Installing Casement Windows

3. High Energy Efficiency

Casement windows are commonly considered the most energy-efficient operable window type. When the window is closed, the sash presses securely against the frame's weather-stripping, developing an airtight seal.

4. Boosted Security

Security is a primary concern for any homeowner. Casement windows are notoriously challenging to break into from the outside. The locking mechanism is integrated into the frame, and since the crank lies inside your home, a trespasser can not easily pry the window open from the outside. The majority of contemporary sashes include multi-point locking systems that secure the sash at numerous spots along the frame.
