Skylight / July 9, 2018 / Delphine Demers
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.
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.
You will need to position and mark the opening on the ceiling after the skylight is installed. Take into consideration the size of the room and the amount of light you wish to bring in and select the size and position of the hole accordingly. Once the skylight is installed and the ceiling hole is cut its then a matter of connecting the two with the shaft which is typically constructed from 2x4 or 2x6 lumber. The angles involved typically require some tricky framing and is probably best left to an experienced carpenter. After the framing is completed the inside of the shaft is covered with wood or drywall and the attic side is insulated to minimize heat loss.
