Skylight / July 12, 2018 / Odo Vaillancour
The air near the ceiling is automatically cooled when fresh air flows in from outside. These roof skylights are so designed that they open and close a little to let in the fresh air. The glass tilts at about 45 degrees. There is a small handle to manually open the venting roof skylight. You crank the handle slightly to open or close or adjust the angle and position of the glass. The venting roof skylights are located in the ceiling of the house and are hard to reach so there is an extension to the handle. Otherwise every time you want to open or shut the venting roof skylight you will need a ladder or a high stool. Nowadays electronically operated venting skylights are also becoming very popular.
If the room you intend to illuminate with the skylight has an open ceiling with no attic space above you can install the skylight without needing to construct a light shaft. This is by far the simplest installation and it offers the maximum amount of light and a view of the sky. For ceilings with an attic space above a light shaft must be constructed that connects the skylight to the room. Skylight shafts take one of three forms: Straight in which the shaft drops vertically from the roof to the ceiling and is the same dimension as the skylight itself. This type is the easiest to construct but because of its offset angle relative to the skylight offers the least amount of light.
These are like Gods own television screens! Moreover skylights will usually bring in more light than windows and are a great alternative to artificial lighting. Skylights have been used in housing and other architecture from time immemorial and these can never go out of style. Very often skylights have been found in old churches. They add certain warmth and charm to the somber interiors. Skylights are used frequently in modern architecture as well and many modern malls hospitals restaurants and other large public places make use of skylights for natural daylight to light up common areas. When selected carefully and installed an energy-efficient skylight can help minimize heating cooling and lighting costs to very large extent.
