Skylight / July 16, 2018 / Baptiste Allain
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.
For one thing skylights are positioned in such a way that they are inaccessible unless they are operated by remote. Even in cases of motorized skylights which are easily manipulated there are still some disadvantages that are inherent to skylights that are not present or minimized in windows. Vertical windows lose less heat by convection when compared to skylights. Also since windows are generally protected by overhangs or shrubs they lose less heat by radiation. On the other hand skylights are directly exposed to the sky. Thus they lose more heat by radiation. Proper insulation can reduce this heat loss to a large extent. In the summer season skylights are more exposed to the direct heat of the sun than 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.
