Using a ‘photocatalytic’ process, the PhotoActiv™ surface reacts with ultra-violet rays from natural daylight to break down and disintegrate organic dirt.
The second part of the process happens when rain or water hits the glass. Because Pilkington Activ™ is ‘hydrophilic’, instead of forming droplets the water spreads evenly over the surface, and as it runs off takes the dirt with it. Compared with conventional glass, the water also dries off very quickly and does not leave unsightly ‘drying spots’.
