Different types of windows used in Buildings

Windows are classified into the following main types:

1. Casement windows: A window having shutters which open like a door is called a casement window. This type of window consists of a frame and shutters composed of vertical and horizontal sash bars, styles, top and bottom rails. Its frame is made and fixed in the wall in the same manner as the door frame. Such windows are provided for
admission of light and air in a room. Shutters of such windows may open inward or outward and are hung to the frame with butt hinges.

A casement window may be full panelled or fully glazed or partly panelled and partly glazed. A window provided with panels as a whole is known as fully panelled window, whereas a window with glass panes as a whole is called a fully glazed window. When the upper portion of a casement window is glazed and the lower portion is panelled it is called partly panelled and partly glazed window.

2. Casement window with fan light: The Integral part of a door or a window at its top, meant for more light and ventilation of the room is known as fan light. This type of window is recommended when the headroom is restricted and a separate ventilator cannot be provided. This window saves one sill member as the head of the door or
window frame acts also as a sill of frame for the fan light. It also economises the construction as it saves one lintel because in general two lintels are provided, one at the top of the door or window opening and the other at top of the ventilator.

3. Corner windows: The window provided at the corner of a building is called a corner window. This is an ordinary window provided for entrance of more light and air in a room. This window saves one post since the central is common to both the windows.

4. Bay windows: The window which projects outside the room of a building is called a bay window. This type of window provides an increased space for admitting more light and air in the room. This window also enhances the architectural appearance of the buildings.

5. Dormer windows: The vertical window provided in the pitched roof is called dormer window. This type of window is used for admitting light and for ventilation of the room. It may be gable type or shed type.

6. Lantern windows: The window provided in the flat roof of a room in which a natural light from ordinary windows cannot be achieved is called a lantern window. This type of window projects above the normal surface of the roof. Such windows are provided for admitting light in inner rooms of a building.

7. Clerestory window and ventilators: The ventilator provided in a wall under the roof but above the adjoining verandah of a room is called a clerestorey window or C-window. When there is no adjoining verandah, the arrangements made near the roof level for natural ventilation and entrance of light into the room is called ventilators. The leaf of a ventilator is fixed to the stiles by swinging it on two horizontal pivots so that it can be
opened or closed by means of cords.

8. Sky light: The window provided in the sloped roof with its top parallel to the surface is called a sky light. This type of window is provided for ventilation and admitting light from a pitched or stoped roof.
