Skylight / July 15, 2018 / Arnou Gabriaux
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.
Fixed skylights are among the most popular and they come in a wide variety of shapes. Ventilated skylights can be opened and closed to allow the passage of air. These make a great addition to bathrooms and kitchens and they can be controlled by temperature sensor remote control wall switch and manual or motorized cranks. Tubular skylights are among the newest styles. They are popular because they are small and can be used where full-sized skylights will not fit. They allow for the passage of light and theyre installed the same way as regular skylights. Flat glass skylights are built into a framework (usually made of wood rubber or metal) and can be placed directly into a cut hole in your roof.
