Market Overview
Smart glass refers to advanced glazing materials that can alter their light transmission properties dynamically, depending on environmental conditions or user control. These materials use technologies like electrochromic, thermochromic, photochromic, polymer-dispersed liquid crystal (PDLC), and suspended particle devices (SPD) to adjust transparency or opacity.
Applications of smart glass span multiple sectors — from residential and commercial construction, where it enables energy savings and privacy, to automotive and aerospace, where it improves passenger comfort, reduces glare, and enhances design aesthetics.
The key value proposition of smart glass lies in its ability to reduce energy consumption, improve interior comfort, and offer sleek, modern alternatives to traditional shading systems such as curtains or blinds.
