Skylight / July 11, 2018 / Nicolas Charlebois
Tubular skylights An alternative to the conventional skylight which looks like a window in your roof is the tubular skylight. The tubular skylight is a roof-mounted dome which collects natural light and delivers it to the room below. It is less expensive than the conventional skylight because it is designed to fit between roof and ceiling framing eliminating the need for structural modifications. You will commonly see these used in bathrooms hallways and closets but they can be used in any room of your house. The average tubular skylight ranges in size from 10 - 21 inches in diameter which lights a 100-600 square foot interior space.
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.
After the hole is cut the skylight frame is simply attached to the roof sheathing with L-brackets and then the installation is completed using the factory-supplied flashing kit. Ease of installation superior insulating qualities less tendency to scratch and a cleaner finished appearance all add to the popularity and somewhat higher cost of glass skylights. Glass skylights also have a greater number of optional accessories. These include tempered laminated or wire glass; shades and blinds for light control; glass tints for heat retention or to block sunlight; and the ability to open fully or partially for ventilation. Domed acrylic skylights are less expensive than glass.
