Details:
The Pilkington Active self-cleaning glass range is based on a 15nm thick thin-film coating of titanium dioxide. Other varieties of Pilkington Active offer additional features like solar control and low-emissivity energy-saving glass.
Using a "photocatalytic" process, the coating on Pilkington Activ Clear reacts with ultra-violet rays present in natural daylight to break down and disintegrate organic dirt. The second stage occurs when rainwater hits the glass. Pilkington Activ Clear is "hydrophilic" which means that 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 without leaving unsightly drying spots.
