Skylight / July 16, 2018 / Delphine Demers
Skylights are one of the quickest and easiest ways to make any room of your home lighter and brighter adding an open and airy feeling. Ventilating skylights are excellent for kitchens or bathrooms. In addition to providing extra light they also open. This overhead ventilation creates an updraft. Ventilated skylights can be operated by several means: Controlled by temperature sensor Remote control Electric on/off wall switch Manual or motorized hand crank. Fixed skylights are for additional light only. Theyre great for attics bonus rooms or anywhere you want extra illumination without entrance or exhaustion of air. Styles and sizes vary from domes to rectangles.
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.
Obviously skylights provide added day lighting and they may even offer ventilation. However heat gain and loss is also a consideration you should make. Many modern skylights feature sun tracking lenses or mirrored surfaces that provide light without heat loss or gain. Moreover whether a fixed skylight or similar alternative is better than a ventilated skylight is a question youll want to answer. Remember ventilating can help with temperature control but it is also important for preventing the buildup of moisture. Take some time to speak to your skylight or roofing professional so that you can be sure to choose the right skylight.
