Pilkington Activ™ Self-Cleaning Glass
Activ glass uses the forces of nature to maintain its clear appearance without leaving unsightly streaks. In a dual-action process organic dirt is broken down by daylight and is then washed away by rain, thus making it environmentally friendly and very easy to maintain.

Benefits of self-cleaning glass
If you clean your own windows you will save time and energy as cleaning windows will be a thing of the past; if you currently employ a window cleaner, you'll save money to spend on things you really enjoy.

How self-cleaning glass works
After years of development, Pilkington Activ™ is the world's first self-cleaning glass to use 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.
