Skylight / July 16, 2018 / Delphine Demers
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.
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.
Tubular skylights An alternative to the conventional skylight which looks like a window in your roof is the tubular skylight. The tubular skylight is a roof-mounted dome which collects natural light and delivers it to the room below. It is less expensive than the conventional skylight because it is designed to fit between roof and ceiling framing eliminating the need for structural modifications. You will commonly see these used in bathrooms hallways and closets but they can be used in any room of your house. The average tubular skylight ranges in size from 10 - 21 inches in diameter which lights a 100-600 square foot interior space.
