Your guide to Pilkington Activ™ self-cleaning glass

A revolution in glass

Self-cleaning glass has been described as an impossible dream. Yet, following an intensive research and development programme 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.

Here are some answers to questions you may have about Pilkington Activ™ and how it works.

Exactly what is self-cleaning glass?
Pilkington Activ™ is an ordinary glass with a special coating on the outside that has the unique dual-action. Once exposed to daylight, the coating 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 coating is securely bonded to the glass — so it can only be affected if the surface of 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 discolour.

How long will it last?
Tests have shown that the coating will last as long as the glass itself.

Is it environmentally friendly?
Yes. The coating 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" is kinder to the environment than ordinary glass.
