Skylight / July 11, 2018 / Nicolas Charlebois
For one thing skylights are positioned in such a way that they are inaccessible unless they are operated by remote. Even in cases of motorized skylights which are easily manipulated there are still some disadvantages that are inherent to skylights that are not present or minimized in windows. Vertical windows lose less heat by convection when compared to skylights. Also since windows are generally protected by overhangs or shrubs they lose less heat by radiation. On the other hand skylights are directly exposed to the sky. Thus they lose more heat by radiation. Proper insulation can reduce this heat loss to a large extent. In the summer season skylights are more exposed to the direct heat of the sun than windows.
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.
The structure of the house is another deciding factor. If there are beams pillars or pipes in the way the skylight on the roof may not get the right amount of visibility. Making structural changes is not an affordable option in most cases. So it is better to evaluate the room before you place skylights on the roof. In most cases skylights should be built into the house at the time of drawing the design of the house. In case skylights are introduced at a later point of time care must be taken to ensure that they are placed correctly and installed properly. Skylights are overhead windows often in a roof that allow sunlight to filter inside any enclosed area; they are a great natural light option to artificial lighting solutions during the daytime.
