Special glass refers to various types of glass that have unique properties or functionalities, making them suitable for specific applications. Examples include tempered glass, which is heat-treated for increased strength and safety, and laminated glass, which consists of layers that hold together when shattered, enhancing security and sound insulation. Another type is smart glass, which can change its transparency or color in response to electrical signals or environmental conditions. This technology is often used in modern buildings and vehicles to improve energy efficiency and privacy. Special glass plays a crucial role in architecture, automotive design, and electronics.
