Skylight / July 11, 2018 / Nicolas Charlebois
The acrylic dome is typically mounted in an aluminum frame which is in turn mounted on a box called a "curb." Once the hole is cut in the roof to the manufacturers specifications the curb is typically constructed on-site to raise the skylight above the level of the roof sheathing. Site-built or factory-supplied flashings are used to seal the roofing around the curb. Domed skylights are available in clear smoked bronze or other tints. Some domed plastic skylights are flush mounted which means that the lens piece and flashing piece are both made of plastic and then placed on the roof without a curb. The problem with this type is that they are loud and very susceptible to leakage.
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.
Skylights let natural light stream into your home bringing warmth and a feeling of spaciousness. When properly selected and used they can reduce your need for electric lighting and minimize your heating and cooling costs. There are also health benefits to this wonderful sunlight that shines on us. If you lack sufficient sunlight on your skin you will suffer health effects. Thats because the human body was designed to be exposed to sunlight on a frequent basis. We evolved after all under the natural sun not under fluorescent lighting. Our environment was one with plentiful sunlight. Skylights can provide up to 30% more natural light than vertical windows while making a small space seem bigger.
