Skylight / July 16, 2018 / Delphine Demers
Roof skylights bring in natural sunlight into your house and add to the style of your house. But those who install it are always worried about one problem and that is a leaking roof skylight. It cant be denied that there is increased risk of a leak but if you install and seal your skylight properly you can make your skylight absolutely leak proof and secure. Skylights have a reputation that they always leak. But it is not so. You must not let this rumor stop you from installing a roof skylight that you have always wanted. There has been great progress in technology and techniques used in installing a roof skylight and if the skylight is installed properly there is hardly any chance of it developing a leak.
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.
It is recommended that the skylight size should never be more than five percent of the floor area in rooms with many windows and not more than fifteen percent of the rooms total floor area for spaces with very few windows. Skylights on north-facing roofs provide cool illumination while east-facing roofs provide maximum light and heat in the morning. West-facing skylights provide afternoon sunlight and heat. South-facing skylights provide more passive solar heat than any other location. Skylights are an excellent way to bring more natural light into your home. Just one skylight can dramatically transform your room by adding 30% more natural light than a window. This helps you save energy and makes your home warmer during the winter.
