Skylight / July 9, 2018 / Delphine Demers
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.
To make sure that glass skylights are protected these are made of tempered glass on the outside and have a laminated pane on the inside. Position: Where and how you place skylights within the home is equally important. Location plays a vital role in natural lighting and solar heating. When they are placed on the roof and facing the north you can expect consistent but cool lighting. Skylights that face the east provide maximum solar energy in the mornings while those facing the west will give maximum afternoon sunlight. If heat is a problem you may install skylights in the shade of a tree or have a shading device on top of the skylight. The slope at which skylights are placed also controls the amount of heat and light received. Before buying skylights for the home do a little research. Prices tend to vary from a few hundred to a few thousand dollars. Price climbs with the addition of features like shading devices remote control and special glazing.
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.
