Skylight / July 7, 2018 / Arnou Gabriaux
If the room you intend to illuminate with the skylight has an open ceiling with no attic space above you can install the skylight without needing to construct a light shaft. This is by far the simplest installation and it offers the maximum amount of light and a view of the sky. For ceilings with an attic space above a light shaft must be constructed that connects the skylight to the room. Skylight shafts take one of three forms: Straight in which the shaft drops vertically from the roof to the ceiling and is the same dimension as the skylight itself. This type is the easiest to construct but because of its offset angle relative to the skylight offers the least amount of light.
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.
Fixed skylights are among the most popular and they come in a wide variety of shapes. Ventilated skylights can be opened and closed to allow the passage of air. These make a great addition to bathrooms and kitchens and they can be controlled by temperature sensor remote control wall switch and manual or motorized cranks. Tubular skylights are among the newest styles. They are popular because they are small and can be used where full-sized skylights will not fit. They allow for the passage of light and theyre installed the same way as regular skylights. Flat glass skylights are built into a framework (usually made of wood rubber or metal) and can be placed directly into a cut hole in your roof.
