Coated glass is a type of glass that has a thin layer of material applied to its surface. This coating can enhance various properties, such as energy efficiency, UV protection, and glare reduction. Common coatings include low-emissivity (Low-E) coatings, which help control heat transfer, and reflective coatings, which can reduce solar heat gain. The coatings are typically made from metals or metal oxides and are applied using processes like sputtering or chemical vapor deposition. Coated glass is widely used in buildings, vehicles, and solar panels, contributing to improved comfort and energy savings in various applications.
