Electrochromic Glass (24mm-32mm as IGU)
Electrically tintable smart glass IGU that dynamically controls solar heat gain and visible light transmission, offering 20-34% energy savings compared to static glazing
Electrically tintable smart glass IGU that dynamically controls solar heat gain and visible light transmission, offering 20-34% energy savings compared to static glazing
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.
