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.
To maximize the energy efficiency of skylight windows you must choose the material carefully. Both glass and plastic skylights have their unique benefits and disadvantages. Glass is more durable but there are limitations in shape. It is also quite expensive. On the other hand plastic is flexible and can easily be bent or stretched to different shapes. It is inexpensive too. But plastic glazing has a tendency to change color after a while. More importantly irregular shapes lead to more heat loss as larger surface areas are exposed. Windows VS Skylights: It is wrong to believe that skylights can replace or take the place of windows.
Typically flat glass skylights include all the installation materials and they are among the easiest to install. Moreover because they are glass these flat skylights are less likely to scratch. Domed acrylic skylights are among the most affordable especially compared to glass alternatives. These skylights are available in a variety of tints making them an attractive addition to any home or room. Unfortunately domed acrylic skylights do not offer the same noise protection as glass varieties and they tend to be more susceptible to leaking. Function Now that you know a little bit about the types of skylights available you should take some time to consider their function.
