Description

Electrochromic glass is an advanced glazing technology consisting of multi-layered ceramic coatings (less than 1/50th human hair thickness) that tint or clear when low voltage (< 5V DC) is applied. Available in double (24mm) or triple (32mm) IGU configurations, it provides dynamic solar control with U-values of 0.14-0.29 W/m²K and variable SHGC from 0.05-0.48, eliminating the need for blinds while maintaining views.

Electrochromic technology was first developed in the 1960s but only became commercially viable for architectural applications in the 2000s. Major manufacturers like SAGE Electrochromics (now Saint-Gobain's SageGlass) pioneered mass production in 2010. Australian adoption began around 2015 with high-profile projects in commercial buildings. The technology has evolved from simple on/off switching to graduated tinting with zone control and predictive algorithms based on solar positioning and weather data.
