Casement windows are hinged windows that open by the turn of a crank. They can be hinged on the left or the right to open fully outward. Typically, casement windows are split into two separate panes with the hinges placed at each side of the frame.
Casement windows are ideal when the weather turns warm. They can be opened at any angle, and they’re great for ventilation. Yet when closed they provide better insulation than many single hung and double hung windows.
Unlike casement windows, awning windows are hinged at top. When opened, they create the awning effect that give them their name. And you can keep an awning window open while it’s raining outside without any water entering your home.
Like casement windows, awning windows are very well sealed when closed and provide better insulation than many other window styles.
