The Smart Window industry is witnessing transformative growth as buildings and vehicles become increasingly energy-efficient, connected, and sustainable. Smart windows, also known as switchable or dynamic glass, use advanced technologies such as electrochromic, thermochromic, and photochromic materials to automatically control light, heat, and privacy. They can adapt to external conditions or be manually adjusted via apps or building automation systems, offering both comfort and energy savings.

With the growing global emphasis on green building standards, smart cities, and net-zero energy targets, the smart window industry is set to become a key pillar of modern architectural and automotive innovation.
