Skylight / July 14, 2018 / Onfroi Berger
For one thing skylights are positioned in such a way that they are inaccessible unless they are operated by remote. Even in cases of motorized skylights which are easily manipulated there are still some disadvantages that are inherent to skylights that are not present or minimized in windows. Vertical windows lose less heat by convection when compared to skylights. Also since windows are generally protected by overhangs or shrubs they lose less heat by radiation. On the other hand skylights are directly exposed to the sky. Thus they lose more heat by radiation. Proper insulation can reduce this heat loss to a large extent. In the summer season skylights are more exposed to the direct heat of the sun than windows.
These are like Gods own television screens! Moreover skylights will usually bring in more light than windows and are a great alternative to artificial lighting. Skylights have been used in housing and other architecture from time immemorial and these can never go out of style. Very often skylights have been found in old churches. They add certain warmth and charm to the somber interiors. Skylights are used frequently in modern architecture as well and many modern malls hospitals restaurants and other large public places make use of skylights for natural daylight to light up common areas. When selected carefully and installed an energy-efficient skylight can help minimize heating cooling and lighting costs to very large extent.
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.
