Skylight / July 11, 2018 / Nicolas Charlebois
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.
For example the optimum slope for a south-facing skylight in Columbus Ohio at 40º North latitude is 45º to 55º. Every skylight has a "shaft" which governs how much light is admitted into the room below. If all four sides are flared then the light is spread over a wide area. If your skylight has a shaft with perpendicular sides the light is focused straight below. If your skylights shaft is flared on only one or two sides then the light is sprayed in the flared direction. Ventilation If you wish you can have a skylight which also provides ventilation as well as light to your room. This allows you to release the hot air which collects at your ceiling.
This is ideal for cubicles or small offices even restrooms. The places where tubular skylights are most effective are in the bottom floor of a multi-story building in order to light the space with natural sunlight warehouses private offices or to prevent heat loss and for solar gain. The installation of tubular skylights requires a professional installer who can work with the thickness of your ceiling and angles to get the most out of your skylight. The top panel of the skylight will be affixed to your roof with the channel running through the ceiling completely hidden from sight with the bottom window attached on the visible area of the ceiling.
