Skylight / October 18, 2018 / Arnou Gabriaux.
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.
A skylight might seem like the easiest option for rooms that are cramped dingy and dark. In many cases it is but only if the right kind of skylight is combined with the right type of roof. Fixing a skylight on the roof is not like placing a window in the wall. Most of us think only of the interior when we fix skylights. But did you know that your first priority should be your roof followed by the positioning of the skylight on the roof? The shape of the roof is a vital to the selection of skylights. There are different skylights for sloped roofs and different skylights for flat roofs. Incorrect installation can lead to problems in the future.
Solar heat control glazing - Manufacturers use various glazing methods to reduce the impact of summer time solar heat gains and winter time heat losses. These come in the form of heat-absorbing tints double and tripled paned skylights and low-emissivity coatings. Slope When your window professional installs your skylight one of the factors they will take into consideration is the slope. The slope or tilt of the skylight affects the amount of solar heat gain. A low slope on your skylight admits more solar heat in the summer and less in the winter which is the opposite of the effect you are trying to achieve As a rule of thumb you want to achieve a slope equal to your geographical latitude plus 5 to 15 degrees.
There must be a clear opening in the area where the skylight is to be placed. A skylight that faces the East lets in plenty of morning sunshine while one that faces the West brings lets in the afternoon sunshine. It is important to know the amount of light and the type of light your skylight lets in. Afternoon sunlight can become uncomfortably hot if you live in a warm and dry place. The size of the room also has a bearing on the effectiveness of the skylight on your roof. If the room is small your choices are severely limited as skylights are best suited for large rooms. If you still want a skylight for a small room it is best to opt for an elegant pyramid skylight. This gives the illusion of space.
