Sometimes known as side hung windows, casement windows come with one sash that is connected to the outer frame through butt hinges or friction hinges, which are excellent for more air circulation. uPVC Casement windows are very energy efficient and come in different variations like side hung, and top hung.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.
