Skylight / July 7, 2018 / Arnou Gabriaux
Skylights let in outdoor light cutting down on both heating and electricity costs. When a skylight is designed and installed properly it can light an entire room provide heat and improve the appearance of your home or business. These are just some of the basic benefits to using skylights; you could even look into utilizing the solar power from your skylights in different ways to live more eco-friendly. No matter what type of home or business ceiling thickness you have there is a skylight design that will work for you. For buildings with thick ceilings attics or multi-storied buildings often utilize tubular skylights. For the layperson the easiest way to describe tubular skylight design is a long tubular channel with a collector at the top and a diffuser at the bottom that will illuminate an area between 75 and 150 square feet per skylight.
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.
The air near the ceiling is automatically cooled when fresh air flows in from outside. These roof skylights are so designed that they open and close a little to let in the fresh air. The glass tilts at about 45 degrees. There is a small handle to manually open the venting roof skylight. You crank the handle slightly to open or close or adjust the angle and position of the glass. The venting roof skylights are located in the ceiling of the house and are hard to reach so there is an extension to the handle. Otherwise every time you want to open or shut the venting roof skylight you will need a ladder or a high stool. Nowadays electronically operated venting skylights are also becoming very popular.
