Skylight / July 11, 2018 / Nicolas Charlebois
Skylights are best suited to catch sunlight from the overhanging clouds. In addition to this skylight windows allow a deeper penetration of the suns light into the structure of the house in such a way that it is less obtrusive. Skylights also keep heating and cooling costs down. Skylights are your windows to the heaven. They can breathe drama into any living space. And they are all the rage these days. In such a scenario it is easy for people to forget important considerations while choosing skylights. Energy problems that influence windows operate just as strongly or even more so in skylights. For instance heat loss heat gains solar gains ventilation and water pooling affect skylight windows too.
Angled where the shaft is parallel to the pitch of the skylight. It too is the same dimension as the skylight but its straight-in angle offers more light than a straight shaft. Angled shafts also are used to connect two locations that cannot otherwise be aligned. This occurs when the skylight must be installed in a particular spot - between two trusses for example - and the shaft opening is likewise limited to a particular location on the ceiling that is not directly under the skylight. Splayed or pyramid in which the ceiling opening is larger than the skylight opening in width length or both. This type although a little harder to construct is the most popular simply because it allows a smaller skylight to illuminate a larger area.
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.
