Types of Windows used Today
Common Double-hung sash window
The traditional window. Double hung windows give one great control of a rooms ventilation. They have an upper sash that slides down and a lower one that slides up. The two parts are not necessarily the same size. Springs, weights, or friction mechanisms help move and position the sash. With certain types, the sash can be manipulated for cleaning purposes.

These attached to the sashes using pulleys made with cords or chains.

Casement windows are side-mounted on hinges They open easily for cleaning on the hinge, swinging inward or outward. In the US they are usually opened with a crank, but in Europe they commonly use projection friction stays and espagnolette locking.
Awning windows are essentially horizontal casements that open out at the bottom with a hinge on top. These are often used for security but still give the rooms inhabitant a good view.
