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
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.
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. Tests have 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, self cleaning glass is kinder to the environment
than ordinary glass.
