Skylight / July 12, 2018 / Odo Vaillancour
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 means more heat is going to find its way into the room at the most inopportune times of the day. The problem can be rectified by careful selection of skylights. Skylights in the home are the easiest least expensive and most effective way of sprucing up your home and giving it a makeover. The reason why skylights are becoming immensely popular is the way they encompass a slice of the sky within the home. They can thus impart roominess to any room. But to get maximum impact from skylights in the home it is important to understand the design positioning and size of skylights. Size: As a rule specialists believe that skylights illuminate a room that is roughly 20 times the size of the room.
