Skylight / July 16, 2018 / Delphine Demers
Your ventilating skylight can be operated by one of three ways: Manual skylight controls - These are opened by your use of an extended rod to manually crank the skylight open. These are designed for ceilings of less than 15 feet. Electronic skylight controls - A simpler model of this type of control is wired to a wall mounted switch which opens and closes the skylight. More complex models are controlled by a special wall console of a wireless remote control. Automatic operating controls - With this type of control integrated heat sensors trigger the skylight to open when the interior heat reaches a preset temperature. Exterior sensors automatically close the unit when they sense moisture.
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.
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.
