Pilkington’s Activ glass uses the power of the sun to clean itself. Activ is manufactured with the same advanced pyrolytic technology used to produce glass panels for electronic and photovoltaic solar-cell applications. Activ loosens dirt, gradually breaking down organic residue with a special PhotoActiv surface that uses energy from daylight.
When it rains, the water sheets off the surface of the glass, removing dust particles and inorganic dirt so that windows dry without spots and streaks. Under most conditions natural rain is sufficient to keep the window clean, and in dry weather a quick spray with the hose will achieve the same results. Activ has been shown to dramatically reduce the need for window cleaning, providing crisp, clear views.
