Skylight / July 16, 2018 / Baptiste Allain
Skylights are usually covered with translucent or transparent material to allow light to pass through while also protecting from extreme weather conditions. A Skylight is a great way to allow more light into your home through a flat or sloped window built into the roof structure for daylighting. Adding a skylight can almost immediately open up any room and make it lighter and brighter adding a sunny airy feeling. Skylights come in many styles and designs. They can be rectangular oval triangular or any odd shape and are perhaps the most beautiful way to enjoy the rain as you see it fall over your head. Windows cannot recreate the drama and magic that skylights can add to your house.
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.
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.
