Skylight / July 16, 2018 / Delphine Demers
Fixed skylights are among the most popular and they come in a wide variety of shapes. Ventilated skylights can be opened and closed to allow the passage of air. These make a great addition to bathrooms and kitchens and they can be controlled by temperature sensor remote control wall switch and manual or motorized cranks. Tubular skylights are among the newest styles. They are popular because they are small and can be used where full-sized skylights will not fit. They allow for the passage of light and theyre installed the same way as regular skylights. Flat glass skylights are built into a framework (usually made of wood rubber or metal) and can be placed directly into a cut hole in your roof.
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.
When these are pulled away and removed the drenched and water damaged roof beams come into view. Moisture comes from both inside and outside. Weather isnt the only thing that causes skylights to leak. Warm air from inside the house can catch in the skylight as it rises on warm air and then drips down onto furniture and valuables below. Modern skylight replacements can come with what is called low-e glass. This low emissivity glass keeps energy meant to heat or cool a room in and helps to reflect heat and cold out and away from the light itself. This is usually done through a special film that the glass is coated with. This film can block out UV rays and comes in many different filtering shades.
