Awning
Awning windows are similar to a casement window that is turned on its side except that they have very different and special hardware. This special hardware allows the window to be hinged at the top and open towards the outside from the bottom.
Awning windows can actually provide some protection from the rain in the open position just like an 'awning'. Awning windows can be combined with Casement windows and Picture windows to create dramatic sightlines and combination windows.
