Skylight / July 11, 2018 / Nicolas Charlebois
The structure of the house is another deciding factor. If there are beams pillars or pipes in the way the skylight on the roof may not get the right amount of visibility. Making structural changes is not an affordable option in most cases. So it is better to evaluate the room before you place skylights on the roof. In most cases skylights should be built into the house at the time of drawing the design of the house. In case skylights are introduced at a later point of time care must be taken to ensure that they are placed correctly and installed properly. Skylights are overhead windows often in a roof that allow sunlight to filter inside any enclosed area; they are a great natural light option to artificial lighting solutions during the daytime.
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.
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.
