Skylight / July 11, 2018 / Nicolas Charlebois
A skylight is like a window which has been placed in your roof. It has a frame specially designed to withstand rain and prevent leakage from rain and snow. To maximize a skylights use of natural light to illuminate a room or its passive solar heating potential you will want to take into consideration how a skylight is positioned. Facing north your skylight will provide fairly constant illumination but will not provide a lot of heat. Facing east it will provide the maximum amount of light and solar heat gain in the morning. Facing west your skylight provides afternoon sunlight as well as heat gain. A skylight facing south provides the greatest potential for winter passive solar heat gain than any other location but will often allow unwanted heat gain in the summer.
If installed badly however they can do a great deal of damage. Many people dont realize how easily that damage can be avoided by purchasing a replacement skylight instead of giving it up altogether. A skylight might be detrimental to a house in many different ways. They require flashing when installed and without proper flashing of aluminum or some other sturdy material the light will leak. Rain and other forms of moist weather will find its way into the house itself. Roof design is very important when choosing and installing a skylight. It is another reason why skylights fail after awhile. The angle or tilt of a roof and the angle at which the skylight is set will determine how strong and supported the light is.
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.
