Casement windows can be a great window choice given the right application. The two main types of casement windows are single frame casement windows and double casement windows.
Casement windows offer a couple of unique advantages.
Ease of operation: Casement windows open via a mechanical crank and are therefore are typically easier to open than a single or double hung window.
Catch a breeze: Since casement windows open fully and “outward” it is possible to catch a breeze with the window and direct more air flow into the home.
Energy Efficient: Due to the nature of their design, casement windows form a very tight seal when closed. With an Energy Star rating and proper installation, casement windows provide a very energy efficient window solution.
