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.
The air near the ceiling is automatically cooled when fresh air flows in from outside. These roof skylights are so designed that they open and close a little to let in the fresh air. The glass tilts at about 45 degrees. There is a small handle to manually open the venting roof skylight. You crank the handle slightly to open or close or adjust the angle and position of the glass. The venting roof skylights are located in the ceiling of the house and are hard to reach so there is an extension to the handle. Otherwise every time you want to open or shut the venting roof skylight you will need a ladder or a high stool. Nowadays electronically operated venting skylights are also becoming very popular.
To make sure that glass skylights are protected these are made of tempered glass on the outside and have a laminated pane on the inside. Position: Where and how you place skylights within the home is equally important. Location plays a vital role in natural lighting and solar heating. When they are placed on the roof and facing the north you can expect consistent but cool lighting. Skylights that face the east provide maximum solar energy in the mornings while those facing the west will give maximum afternoon sunlight. If heat is a problem you may install skylights in the shade of a tree or have a shading device on top of the skylight. The slope at which skylights are placed also controls the amount of heat and light received. Before buying skylights for the home do a little research. Prices tend to vary from a few hundred to a few thousand dollars. Price climbs with the addition of features like shading devices remote control and special glazing.
