What advantage does coating glass have?

Reflective glass is a coating or multilayer of metal, alloy or metal compound on the glass surface to change the properties of the glass. According to different properties, it can be divided into heat reflecting glass and low radiation glass. Thermal reflection (sunlight control) glass is generally coated with one or more layers of metal or its compound thin film on the glass surface, such as chromium, titanium or stainless steel, so that the product is rich in color, with appropriate transmittance to visible light, high reflectance to near-infrared light and low transmittance to ultraviolet light.

Therefore, also known as sunlight control glass. Compared with common glass, the shading coefficient is reduced, that is, the shading performance is improved, but the heat transfer coefficient is not changed much. LOW radiation glass (low-e), is a multi-layer plating silver on the glass surface, composed of metal or other compounds such as copper or tin film, the product of the transmittance of visible light is relatively high, and has high reflectivity to the infrared, has good heat insulation performance, due to poor film strength, are usually made of hollow glass to use and not used alone.
