Pilkington Activ™ - About the Glass
Self-cleaning glass has been described as an impossible dream. Yet, following an intensive research and development program by Pilkington – inventors of the universally used float glass process, and the world's leading glass manufacturer – new Pilkington Activ™ does just that.
Its unique dual-action uses the forces of nature to help keep the glass free from organic dirt, giving you not only the practical benefit of less cleaning, but also clearer, better-looking windows.
Exactly what is self-cleaning glass?
Pilkington Activ™ is an ordinary glass with a special surface on the outside that has the unique dual-action. Once exposed to daylight, the surface chemically reacts in two ways. First, it breaks down any organic dirt deposits and second, rain water 'sheets' down the glass to wash the loosened dirt away.
Does the special coating change the glass?
From certain angles it has a slightly greater mirror effect than ordinary glass, with a faint blue tint. Otherwise, the glass is just like any other.
Can it be scratched or rubbed off?
The PhotoActiv(tm) surface is an integral part of the glass itself, so it can only be affected if the glass itself is damaged; for example, by pointed objects, abrasive cleaners or steel wool. Our tests have also shown it will not flake off or discolor.
How long will it last?
Tests have shown that the continuous-cleaning surface will last as long as the glass itself.
Is it environmentally friendly?
Yes. The surface contains harmless chemical substances already found in the home, in such things as toothpaste and paint. In fact, with only small amounts of cleaning agents needed, Pilkington Activ™ self-cleaning glass is kinder to the environment than ordinary glass.
