Electrochromic glass is a type of smart glass that can change its tint or opacity when an electrical voltage is applied. This technology allows the glass to control the amount of light and heat entering a space, enhancing energy efficiency and comfort. It is commonly used in windows, skylights, and automotive applications. The glass contains layers of materials that react to electricity, altering their color. When activated, it can transition from clear to dark, providing privacy and reducing glare. Electrochromic glass is increasingly popular in modern architecture and design for its aesthetic and functional benefits.
