For homeowners with beautiful landscapes or gardens, the lack of dividers (unless ornamental grids are included) provides a picture-window impact while still allowing for airflow.
3. High Energy Efficiency
Casement windows are commonly considered the most energy-efficient operable window type. When the window is closed, the sash presses firmly versus the frame's weather-stripping, creating an airtight seal. Unlike sliders, which need a certain amount of "play" in the tracks to move, the compression seal of a casement window reduces air seepage and drafts.

Security is a primary issue for any home owner. Casement windows are notoriously tough to get into from the exterior. The locking mechanism is incorporated into the frame, and because the crank is situated inside your home, a burglar can not quickly pry the window open from the exterior. The majority of modern casements include multi-point locking systems that secure the sash at a number of spots along the frame.
