Casement Windows

A casement window is any window that is attached to its frame by one or more hinges. Specifically, windows attached to the frame on the side (windows hinged at the top are awning windows, but more on that later). Basically they're like doors, only instead of opening with a knob they open with a crank.They Provide Excellent Ventilation – The hinged design of the casement allows the window to swing fully open, making casement windows ideal for large rooms that require lots of airflow.
