Skylight / July 16, 2018 / Baptiste Allain
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.
Skylights may seem inexpensive at first glance since a quality 2x4 foot skylight along with a flashing kit costs anywhere from $100 to $400. However you need to consider adding another $3000 for installation costs. That being said you first need to carefully evaluate if installing a skylight is the right thing for your home. Till recently having a roof slope determined if you could install a skylight. Flat roofs or those which were too steep required special tools and techniques. However many of the skylight kits available today include a comprehensive installation kit and procedures which permits it to be installed on all types of roofs.
Typically flat glass skylights include all the installation materials and they are among the easiest to install. Moreover because they are glass these flat skylights are less likely to scratch. Domed acrylic skylights are among the most affordable especially compared to glass alternatives. These skylights are available in a variety of tints making them an attractive addition to any home or room. Unfortunately domed acrylic skylights do not offer the same noise protection as glass varieties and they tend to be more susceptible to leaking. Function Now that you know a little bit about the types of skylights available you should take some time to consider their function.
