Skylight / July 12, 2018 / Odo Vaillancour
Skylight windows are a wonderful addition to a home. Theres no doubt about it. But a lot depends on where exactly the house is located. Skylight windows are best suited for cool climates where the rays of the sun are not very harsh. Fortunately many places in the US have just this kind of weather. When used in such places skylight windows become the most important source of solar heating. And even when the sun is wobbly and there is little sunshine entering the room large skylight windows make the room look airy and bright dispelling the gloom. In areas where there is limited light and heat vertical windows are less efficient than large skylights because vertical sunlight is scant.
The acrylic dome is typically mounted in an aluminum frame which is in turn mounted on a box called a "curb." Once the hole is cut in the roof to the manufacturers specifications the curb is typically constructed on-site to raise the skylight above the level of the roof sheathing. Site-built or factory-supplied flashings are used to seal the roofing around the curb. Domed skylights are available in clear smoked bronze or other tints. Some domed plastic skylights are flush mounted which means that the lens piece and flashing piece are both made of plastic and then placed on the roof without a curb. The problem with this type is that they are loud and very susceptible to leakage.
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.
