Skylights are windows which are placed-on the roof. They’re used to allow or let natural light enter, and may also be used-to allow in ventilation. Usually, there are certain factors which one needs to consider when selecting a skylight. These factors can include; placement, size, energy efficiency, type and functionality.

Choosing
When choosing a skylight, the size is a key factor since if the size is large then it’ll bring in a lot of heat and light. Usually, the rule says that the skylight will brighten the room 20 times its’ size. Another factor which is just as-important is placement of a skylight. Placing the skylight where there’s lots of sun exposure may lead to the house/room getting over-heated, especially in the warm climates. Basically, a eastern or northern exposure-position is recommended.

Energy efficient window-selection is also very important when you are installing your skylight. Glazing is 1 method of enhancing energy savings. Skylight glazing usually comes in glass or plastic, however, other solar heat control glazing are also available. Plastic-glazing is usually inexpensive, and much sturdier than the other glazing materials. But, plastic glaze lets ultraviolet rays inside, which may result in the discoloration of the objects that are inside a room. Glass skylight-glaze are much more expensive, however, they’re also much more durable & they do not discolor.

Functions
A skylight often has 1 of 3 functions: letting natural light-in, air ventilation, or/and moisture control. A light emitting or a day lighting skylight uses traditional fixed designs, that capture light and also reduce overheating & heat loss. But, they don’t open to provide view or ventilation. A ventilation skylight lets out heat which accumulates near your ceiling. The skylight often vents out of hinged panels, and is often used in the small spaces such as bathrooms and kitchens so as to relieve moisture & regulate the airflow. A moisture control skylight is also available. They’ve an interior channel, that catches-condensation so that it may evaporate later.

A skylight generally brightens up the dark rooms. Even the small units can make a huge difference in regards to the way a room looks and feels. There are numerous brands and different several styles of skylights available to choose from.One of the best choices is the high quality curbed-skylight with energy efficient glazing, with a factory-flashing kit that’s made for it. This kit will not add much to its’ cost, but it’ll mean a leak free installation. There were old fashioned types were there was a single thickness-of glass in the frame, but currently they come with tempered or laminated glass, and low-e & tinted coatings so as to control the heat transmission and the Ultraviolet radiation. Just like a window, a skylight is rated for its’ thermal efficiency by National Fenestration-Rating Council. You may compare U-values and also heat & light transmission rates-of various skylights. Although tinted glass ones are available, it’s best you stick with the clear glass ones because they allow in much more light. In case intense sunlight causes a lot of heat build up or starts to fade the carpeting & the furniture inside, you can add a screen or a shade.
