Skylight / July 15, 2018 / Arnou Gabriaux
To maximize the energy efficiency of skylight windows you must choose the material carefully. Both glass and plastic skylights have their unique benefits and disadvantages. Glass is more durable but there are limitations in shape. It is also quite expensive. On the other hand plastic is flexible and can easily be bent or stretched to different shapes. It is inexpensive too. But plastic glazing has a tendency to change color after a while. More importantly irregular shapes lead to more heat loss as larger surface areas are exposed. Windows VS Skylights: It is wrong to believe that skylights can replace or take the place of windows.
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.
There must be a clear opening in the area where the skylight is to be placed. A skylight that faces the East lets in plenty of morning sunshine while one that faces the West brings lets in the afternoon sunshine. It is important to know the amount of light and the type of light your skylight lets in. Afternoon sunlight can become uncomfortably hot if you live in a warm and dry place. The size of the room also has a bearing on the effectiveness of the skylight on your roof. If the room is small your choices are severely limited as skylights are best suited for large rooms. If you still want a skylight for a small room it is best to opt for an elegant pyramid skylight. This gives the illusion of space.
