Part 3475 of Coto is an electrochromic glazing system, which uses specialized glass with an electrically applied films to control light transmission, glare and heat gain. This technology can be used to reduce energy use in both commercial and residential buildings. The technology is designed to switch between a clear, light-transmitting state and an opaque, non-light-transmitting state, and to offer a full range of shades between these two states. It is a cost-effective, safe and efficient way to reduce energy use, along with providing benefits such as natural light, solar control and privacy.
