A horizontal window unit in which the bottom of the sash swings outward for ventilation. This window can control the amount of air coming in through the window by adjusting the angle of the window.

A window that cannot be opened whose function is limited to allowing light to enter. This type of window is used in situations where light or vision alone is needed as no ventilation is possible through fixed windows.

Window sashes opening on hinges that are generally (but not necessarily), attached to the upright side of its frame. These windows open outwards as against sash windows, which slide up and down. Casement windows are better in situations that are harder to reach as sashes can be difficult to open unless you are positioned properly.

This window is the most popular style for windows due to its versatility and is ideal for any direct window replacements. This can be combined in an extensive series of configurations with or without fixed lights and is suitable for low or medium rise dwellings. Casement window gives a conventional and classic feel to the interior or premises of any place.
