Advantages Of Low-e Glass

Jan 14, 2017

Glass is an important building material, with the improvement of building decorative requirements, amount of glass used in the construction industry is also increasing. Today, however, when the people in the choice of glass Windows and doors of the building, in addition to the aesthetics and appearance features, focusing more on the heat control, refrigeration cost and internal issues such as sunlight and comfortable balance. Upstart in the family that makes coated glass--Low-E glass stand out, become the focus of attention.
Low-e glass, also known as low-e glass in glass-coated metal or other compounds of coating products. Its coating layer having high visible light through the high and far-infrared reflection characteristics, make it with the glass and compared to the traditional coated glass for building purposes, has the following advantages:

Excellent thermal performance
External glazing of heat loss is a major part of building energy consumption, accounting for more than 50% of building energy consumption. Relevant research data shows that glass inner surface of heat transfer with radiation, 58%, it means changing the properties of glass to reduce heat loss, the most effective way is to inhibit surface radiation. Regular float glass emissivity of 0.84 per cent, when coated with a layer based on the silver low-e film, the radiation rate below 0.1 per cent. Therefore, low-e glass doors and Windows of buildings, can greatly reduce Interior heat to the outside due to radiation delivery, achieve the ideal energy-saving effect.
Interior heat loss reduction brought about another significant benefit is environmental protection. Cold season, heating of buildings caused by CO2, SO2 emissions of harmful gases is an important source of pollution. If you are using low-e glass, due to the reduction of heat loss, can significantly reduce fuel consumption for heating, thereby reducing the emission of harmful gases.

Good optical properties
Low-e glass light transmittance of visible light have a high, up to 80% per cent, while reflectance is low, compared to traditional coated glass, optical performance improved significantly. Viewed from the outside, the appearance of more transparent and clear, which is to ensure good lighting of the buildings also used large glass curtain wall, glass Windows and doors light pollution caused by light reflection, creating a more soft and comfortable lighting environment.
Coated glass according to the different product characteristics, can be divided into the following categories: heat-reflective glass, low-e glass (low-e), conductive film glass and so on. Hot reflection glass General is in glass surface plating a layer or multilayer such as chrome, and titanium or stainless steel, metal or its compounds composition of film, makes products is rich of color, for visible has appropriate of transmission rate, on infrared has high of reflection rate, on UV has high absorption rate, so, also called sun control glass, main for building and glass curtain wall; low radiation glass is in glass surface plating by more layer silver, and copper or Tin, metal or its compounds composition of film Department, products on visible has high of transmission rate, Infrared has a high reflectivity, has good insulating properties, mainly used in buildings and cars, ships and other means of transport, due to the strength of the film is bad, generally made of insulating glass; conductive film glass is coated with conductive indium tin oxide thin films on glass surface, can be used for heating, defrosting, demisting of the glass as well as LCD screens
