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.
There is a dimmer type of switch located in the room and with the help of this switch you may open shut or adjust the venting skylight and even fine tune the angle to which you want it tilted. Nowadays the vent roof skylights have become virtually leak proof. The venting roof skylights have great flashing systems which prevent any sort of leakage. But dont think that you may merrily leave the venting skylight open even during storm and rain. Then the water will definitely enter your house. In case the roof skylight has got wet all that you have to do is shut the vent roof skylight and wipe it dry. Just like every other thing you may accessorize the vent skylights too.
Tubular skylights An alternative to the conventional skylight which looks like a window in your roof is the tubular skylight. The tubular skylight is a roof-mounted dome which collects natural light and delivers it to the room below. It is less expensive than the conventional skylight because it is designed to fit between roof and ceiling framing eliminating the need for structural modifications. You will commonly see these used in bathrooms hallways and closets but they can be used in any room of your house. The average tubular skylight ranges in size from 10 - 21 inches in diameter which lights a 100-600 square foot interior space.
