Smart glass, also known as switchable glass or privacy glass, refers to a type of glazing technology that can change its light transmission properties under an applied voltage, light, or heat. The most common technology used in architectural applications is Polymer Dispersed Liquid Crystal (PDLC) technology, which allows the glass to switch instantly from opaque (milky white) to transparent. Other technologies include Electrochromic (EC), Thermochromic, and Photochromic glass. Smart glass is widely used in office partitions, conference rooms, hospitals, retail storefronts, luxury bathrooms, and smart windows for energy efficiency. The global smart glass market was valued at approximately USD 6.5 billion in 2024 and is projected to reach USD 14.2 billion by 2030, growing at a CAGR of around 14.1%.
