Skylight / July 11, 2018 / Nicolas Charlebois
Skylight windows are a wonderful addition to a home. Theres no doubt about it. But a lot depends on where exactly the house is located. Skylight windows are best suited for cool climates where the rays of the sun are not very harsh. Fortunately many places in the US have just this kind of weather. When used in such places skylight windows become the most important source of solar heating. And even when the sun is wobbly and there is little sunshine entering the room large skylight windows make the room look airy and bright dispelling the gloom. In areas where there is limited light and heat vertical windows are less efficient than large skylights because vertical sunlight is scant.
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.
Obviously skylights provide added day lighting and they may even offer ventilation. However heat gain and loss is also a consideration you should make. Many modern skylights feature sun tracking lenses or mirrored surfaces that provide light without heat loss or gain. Moreover whether a fixed skylight or similar alternative is better than a ventilated skylight is a question youll want to answer. Remember ventilating can help with temperature control but it is also important for preventing the buildup of moisture. Take some time to speak to your skylight or roofing professional so that you can be sure to choose the right skylight.
