Skylight / July 12, 2018 / Odo Vaillancour
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.
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.
There is a dimmer type of switch located in the room and with the help of this switch you may open shut or adjust the venting skylight and even fine tune the angle to which you want it tilted. Nowadays the vent roof skylights have become virtually leak proof. The venting roof skylights have great flashing systems which prevent any sort of leakage. But dont think that you may merrily leave the venting skylight open even during storm and rain. Then the water will definitely enter your house. In case the roof skylight has got wet all that you have to do is shut the vent roof skylight and wipe it dry. Just like every other thing you may accessorize the vent skylights too.
