The Pilkington Activ™ Range: A Two Step Cleaning Process

 

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 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.

 

If the thought of spending endless hours cleaning windows puts you off building a new conservatory or installing skylights then self-cleaning glass is precisely what you need. View this demonstration video to gain a better understanding of how self-cleaning glass works with the forces of nature to keep your glass cleaner.

After installation the special coating needs 5 to 7 days exposure to daylight to activate fully.

The coating breaks down organic dirt and by doing so, reduces the adherance of inorganic dirt.

Water droplets spread out to form a "sheet". Dirt particles on the surface are picked up by water and washed off the glass - a remarkable difference you can actually see.
