5. The Single or Double-hung window, classic in appearance, offers excellent control of ventilation. You can raise the lower sash or lower the upper one
A casement window is hinged on one side and swings out when you turn a crank (some are inward-swinging). Because it opens fully, it affords good ventilation and is easy to clean

6. A slider. It's made from two separate sashes-one is fixed, the other slides in a track. Half opens for ventilation. A slider is easy to operate and most types are particularly weather-tight.
Jalousie or "louvered" windows are excellent for ventilation but poor insulators-they leak a great deal of air.

7. An awning window hinges at the top and tilts out at the bottom, providing partial ventilation. These are often used above doors or other windows.
A hopper window hinges at the bottom. A hopper is normally used for ventilation above a door or window, where protected by eaves

The bay window, made from a central sash and two angled side sashes, is a classic favorite for expanding a room with light, views and drama. Angled side windows are often operable casements or double-hung windows.
