5 Things To Know About New Skylights And Energy Efficiency

One time homeowners could see their hard-earned energy dollars drifting upwards from their plastic-domed skylights. Now, it’s not so! Skylights are now possible thanks to technological and manufacturing advances. How are skylights efficient in energy use? At least five ways.


Today’s skylights are made from high-quality Low-E glass. This is low emissivity. A measure of emissivity refers to a number between 0 – 1, where 0 completely absorbs radiant energy while 1 perfectly reflects it. Names indicate the effect desired: a low number will show that the glass reflects ultraviolet and infrared light.

Skylights such as Velux’s E Class products make passive energy efficient use of low-E glass.


Low-E or any other quality glass can reduce outside noise up to 50% when used in skylights.

Velux is a superior product that is up to 25% quieter than double-pane glass. This construction is already quite quiet. Sun tunnels and ultra-quiet sky lights are also available from other leading manufacturers like Sun-Tek and Kennedy.

3-Heat Gain

Low E glass skylights prevent Florida heat from baking your living area, kitchen, and dining room. Heat gain refers to the amount of infrared heat energy that passes through the skylight.

The solar heat gain coefficient (SHGC), of your Florida skylight without the thin, metallic coating on Low E skylight glass would be extremely high. The SHGC of Low-E glass is very close to 0.


These options can help increase the energy efficiency of Low-E skylights.

  • Use skylight blinds to block direct sun at certain times of day
  • Ventilated Skylights which open to let hot air out and fresh breezes in your home
