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.
Before installing a skylight in your home you need to carefully evaluate what type of skylight will work best for you considering your specific requirements and how to install it in a way that it improves your homes energy efficiency. Its a sensible idea to evaluate the energy performance ratings of skylights based on the climate that you live in and the architectural design of your home. In the U.S. you can find labeled energy-efficient skylights which tell you the minimum energy performance rating criteria by climate. The physical dimensions of the skylight also greatly affect the lux level and temperature of the space it is being used for.
To make sure that glass skylights are protected these are made of tempered glass on the outside and have a laminated pane on the inside. Position: Where and how you place skylights within the home is equally important. Location plays a vital role in natural lighting and solar heating. When they are placed on the roof and facing the north you can expect consistent but cool lighting. Skylights that face the east provide maximum solar energy in the mornings while those facing the west will give maximum afternoon sunlight. If heat is a problem you may install skylights in the shade of a tree or have a shading device on top of the skylight. The slope at which skylights are placed also controls the amount of heat and light received. Before buying skylights for the home do a little research. Prices tend to vary from a few hundred to a few thousand dollars. Price climbs with the addition of features like shading devices remote control and special glazing.
