After years of development, Low-E-Plus Self-Cleaning glass is the world’s first self-cleaning glass to use a microscopic coating with a unique dual-action.
The first stage of the cleaning process is “photocatalytic”. In this stage, the coating reacts with daylight to break down organic dirt.
The second stage is “hydrophilic”. Here, instead of forming droplets, rainwater hits the glass and spreads evenly, running off in a “sheet” and taking the loosened dirt with it, also drying quickly without leaving streaks.
