Skylight / July 14, 2018 / Onfroi Berger
To maximize the energy efficiency of skylight windows you must choose the material carefully. Both glass and plastic skylights have their unique benefits and disadvantages. Glass is more durable but there are limitations in shape. It is also quite expensive. On the other hand plastic is flexible and can easily be bent or stretched to different shapes. It is inexpensive too. But plastic glazing has a tendency to change color after a while. More importantly irregular shapes lead to more heat loss as larger surface areas are exposed. Windows VS Skylights: It is wrong to believe that skylights can replace or take the place of windows.
However these surfaces scratch easily and can become brittle and discolored. Glass glazing - This is found in the more expensive skylights. It is more durable than plastic and does not discolor. All glass used for skylights must be made of "safety glazing" a generic term for both tempered and laminated glass. Tempered glass is the most impact resistant. Laminated glass is fabricated with a thin layer of plastic embedded near the center of the glass. Both types keep the glass from breaking into large sharp pieces. Skylights are often made with a tempered glass on the exterior side and a laminated pane on the interior side. This arrangement gives maximum impact resistance while protecting occupants from falling shards of glass.
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.
