Low-Emissivity Energy-Saving Glass is produced by vacuum sputtering coating equipment. In the process of vacuum
sputtering coating, the surface will have a thin-film metal layer combined by metal and electrolyte, which is the so-called coating layer. General energy of sunlight has 51.2% energy in the infrared ray, has 46.8% energy in visible light and has approximately 2% in the ultraviolet and other rays. The metal film of Low-E glass is the most vital point to block the infrared ray and the ultraviolet ray of sunlight. In 380nm-780nm visible light area, the light transmittance is good so it ensures the great lightness.
By blocking the thermal energy from outside, the consuming of air conditioner and the ultraviolet ray transmittance will decrease at the same time. Comparing to clear glass,
reflection and absorption are the main points in traditional coating glass and tinted float glass. In other words, the coating layer of Low-E Glass will make the light transparency up to 80%, and its reflection of far infrared
ray will be 70-90%.
It can use in curtain walls and skylights of modern green buildings to reach the requirements of high light transparency, low reflection, high heat resistance and energy saving. |
