Coated glass is also known as reflective glass. Coated glass covers one or more layers of metal, alloy, or compound film on the surface of the glass. It changes the optical properties of the glass to meet certain specific requirements.
According to the different characteristics of the products, the coated glass can divide into the following categories: heat-reflective glass, Low-E glass, conductive film glass, etc.
The heat reflective glass covers one or more films composed of metals or their compounds such as chromium, titanium, or stainless steel on the surface of the glass. So that it has a different color, has an appropriate transmittance for visible light, and has a higher resistance to the infrared, high absorption rate of ultraviolet rays, so it has another name of solar control glass, mainly used in construction and glass curtain walls;
It covers multiple layers of silver, copper, tin, and other metals or their compounds on the surface of the glass. The reflective low e glass has high transmittance to visible light, high reflectivity to infrared, and good heat insulation performance. Construction, vehicles, ships, and other transportation tools use many low e glass. Due to the poor film strength, it is generally composite in insulated glass;
Conductive film glass:
It covers with a conductive film such as indium tin oxide on the surface of the glass. So it uses for heating, defrosting, defogging of glass, and as a liquid crystal display.
There are many reflective glass production methods, including vacuum magnetron sputtering, vacuum evaporation, chemical vapor deposition, and sol-gel, among others.
The most common usages are heat-reflective glass and Low-E glass. The two production methods are vacuum magnetron sputtering and chemical vapor deposition.
