Casement windows

Casement windows open like doors. Like doors, either the left or right side is hinged (or, more accurately, pivoted), and the non-hinged side locks securely into place with latches. Unlike a door, the casement window opens not by a knob or handle but by means of some variation of a crank.

Casement Windows May Conflict With Each Other

See the picture I have provided? See the problem here? A
bathroom casement that won't let the bedroom casement open all the way. Or vice versa, however you wish to look at it. Before you rush to judgment and say, "Never me" or "A good builder would foresee this problem," consider that reversing one or both casements may just conflict with another casement. The only true solution then is to have a double-hung or slider window. In which case, you no longer have your casements.

2. Casement Windows Are More Exposed to the Elements

Because casements open outward, the edges are exposed to sun, rain, snow, and more. The top edge particularly is exposed and gets weatherbeaten fast. Again, it's easy to rush to judgment and promise that you will religiously close your casement windows prior to the rain, think again.
