Skylight / July 12, 2018 / Odo Vaillancour
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.
There are shades screens and many other window treatments available for the skylights. Thus you may customize even the roof skylight to create a dream house you had always imagined. Jerry asks "I am thinking about installing a skylight. I have heard that there are different types of skylights. My in-laws have one that I think is plastic. It is very noisy when it rains and is extremely hot. Ive heard that there are glass ones. What are the different types? Is there a glass one that doesnt make all the noise in the rain and filters some of the heat? Yes there are different types. Lets discuss them. The term skylight or roof window is often used to describe several styles.
