Skylight / July 11, 2018 / Nicolas Charlebois
After the hole is cut the skylight frame is simply attached to the roof sheathing with L-brackets and then the installation is completed using the factory-supplied flashing kit. Ease of installation superior insulating qualities less tendency to scratch and a cleaner finished appearance all add to the popularity and somewhat higher cost of glass skylights. Glass skylights also have a greater number of optional accessories. These include tempered laminated or wire glass; shades and blinds for light control; glass tints for heat retention or to block sunlight; and the ability to open fully or partially for ventilation. Domed acrylic skylights are less expensive than glass.
Typically flat glass skylights include all the installation materials and they are among the easiest to install. Moreover because they are glass these flat skylights are less likely to scratch. Domed acrylic skylights are among the most affordable especially compared to glass alternatives. These skylights are available in a variety of tints making them an attractive addition to any home or room. Unfortunately domed acrylic skylights do not offer the same noise protection as glass varieties and they tend to be more susceptible to leaking. Function Now that you know a little bit about the types of skylights available you should take some time to consider their function.
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.
