Skylight / July 12, 2018 / Odo Vaillancour
Skylights are best suited to catch sunlight from the overhanging clouds. In addition to this skylight windows allow a deeper penetration of the suns light into the structure of the house in such a way that it is less obtrusive. Skylights also keep heating and cooling costs down. Skylights are your windows to the heaven. They can breathe drama into any living space. And they are all the rage these days. In such a scenario it is easy for people to forget important considerations while choosing skylights. Energy problems that influence windows operate just as strongly or even more so in skylights. For instance heat loss heat gains solar gains ventilation and water pooling affect skylight windows too.
However these surfaces scratch easily and can become brittle and discolored. Glass glazing - This is found in the more expensive skylights. It is more durable than plastic and does not discolor. All glass used for skylights must be made of "safety glazing" a generic term for both tempered and laminated glass. Tempered glass is the most impact resistant. Laminated glass is fabricated with a thin layer of plastic embedded near the center of the glass. Both types keep the glass from breaking into large sharp pieces. Skylights are often made with a tempered glass on the exterior side and a laminated pane on the interior side. This arrangement gives maximum impact resistance while protecting occupants from falling shards of glass.
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.
