Activ selfcleaning glass

Pilkington Activ™ Self-Cleaning Glass uses the forces of nature to maintain its clear appearance without leaving unsightly streaks. Dirt is broken down by daylight and is then washed away by rain, thus making it environmentally friendly and very easy to maintain.
The glass uses a microscopic coating with a unique dual-action. The first stage is “photocatalytic” – the coating reacts with daylight to break down organic dirt. The second stage is “hydrophilic” – 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. The self-cleaning glass can also be combined with a range of different products to offer many additional benefits (such as thermal, solar and noise control).
