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 shape of the skylights installed in your home will impact the design and look of the room. In the past skylights were prone to vapor build-up during the cold season. This vapor would then trickle down as water droplets into the room. However these days it is possible to buy skylights with channels that collect water vapor. More expensive skylights are less vulnerable to condensation related problems. Material: The kind of material used on skylights at home has a direct impact on their look and efficiency. Glass and plastic are the most popular materials used for glazing the skylights. Plastic skylights are less expensive and do not break easily. However plastic glazing may become discolored over time and may even have scratches. Glass on the other hand is scratch proof and does not fade. But it is more expensive and is usually found in commercial structures.
Tubular skylights An alternative to the conventional skylight which looks like a window in your roof is the tubular skylight. The tubular skylight is a roof-mounted dome which collects natural light and delivers it to the room below. It is less expensive than the conventional skylight because it is designed to fit between roof and ceiling framing eliminating the need for structural modifications. You will commonly see these used in bathrooms hallways and closets but they can be used in any room of your house. The average tubular skylight ranges in size from 10 - 21 inches in diameter which lights a 100-600 square foot interior space.
