Coated glass is also called Reflective Glass. It is coated on the glass surface with one or more layers of metal, alloy or metal compound film to change the optical properties of the glass to meet a specific requirement. Heat-reflective glass is generally coated on the glass surface with one or more layers of metal such as chromium, titanium, or stainless steel or a compound thereof, so that the product is rich in color, has suitable transmittance for visible light, and has higher infrared ray reflectivity, high absorption rate for ultraviolet rays, therefore, also known as solar control glass, is mainly used for architectural and glass curtain walls.
