Skylight / July 11, 2018 / Nicolas Charlebois
A skylight might seem like the easiest option for rooms that are cramped dingy and dark. In many cases it is but only if the right kind of skylight is combined with the right type of roof. Fixing a skylight on the roof is not like placing a window in the wall. Most of us think only of the interior when we fix skylights. But did you know that your first priority should be your roof followed by the positioning of the skylight on the roof? The shape of the roof is a vital to the selection of skylights. There are different skylights for sloped roofs and different skylights for flat roofs. Incorrect installation can lead to problems in the future.
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.
Your ventilating skylight can be operated by one of three ways: Manual skylight controls - These are opened by your use of an extended rod to manually crank the skylight open. These are designed for ceilings of less than 15 feet. Electronic skylight controls - A simpler model of this type of control is wired to a wall mounted switch which opens and closes the skylight. More complex models are controlled by a special wall console of a wireless remote control. Automatic operating controls - With this type of control integrated heat sensors trigger the skylight to open when the interior heat reaches a preset temperature. Exterior sensors automatically close the unit when they sense moisture.
