Nanotechnology and Its Uses for Skylights and Glazing
Low e3 glass is standard on all Velux skylights, but what is Low e3? Low-e3 coatings reduce the amount of ultraviolet and infrared light that can pass through glass without compromising the amount of visible light transmitted.
Low e3 coatings are only about 19 nano-meters in thickness. They usually apply 8 coatings on the skylight, for a total thickness of about 150 nano-meters. A human hair is about 75,000 nano-meters thick.
Think of it this way, the coatings keep the glass transparent to visible light, but solid (like chrome or silver) to UV or Infrared light.
- Research and technology development at the atomic, molecular or macro-molecular levels, in the length scale of approximately 1 to 100 nano-meter range.
- Creating and using structures, devices and systems that have novel properties and functions because of their small and/or intermediate size.
- Ability to control or manipulate on the atomic scale.
The nano-scale is about a thousand times smaller than the micro scale (i.e. microscopic) or about 1/80,000 of the diameter of a human hair. Approximately 3 to 6 atoms can fit inside of a nano-meter, depending on the atom. The prefix nano means ten to the minus ninth power, or one billionth (1/1,000,000,000). Nano-scale technologies are the development and use of devices that have a size of only a few nano-meters.
