Exactly what is self-
cleaning glass?

Pilkington ActivTM is normal glass with a special coatin
on the outside that has a unique dual-action. Once
exposed to daylight, the coating firstly breaks down any
organic dirt deposits and secondly, causes rainwater to
‘sheet’ down the glass to wash the loosened dirt away.

A Better Way of Cleaning
Your Windows

Q. What effect does the coating have on the glass?

A. Very little, other than keeping it cleaner for longer! It has no effect on its strength, and only
reduces the amount of light and energy that passes through by about 5%. From certain angles it
has a slightly greater reflective quality than normal glass, with an attractive faint blue tint, giving it a
clearer, brighter appearance.

Q. Can it be scratched or rubbed off?

A. The coating is integral to the glass – it will not flake off or discolour, so it can only be affected if
the surface itself is damaged; for example, by pointed objects, abrasive cleaners or steel wool.

Q. How long will the coating last? Can it be replaced?

A. The coating has been developed to last as long as the insulating glass unit itself. The coating is
permanent and will not need re-applying.

Q. Is it environmentally friendly?

A. Yes. The coating contains harmless chemical substances already found in the home, in items
such as bath oils and toothpaste. In fact, because of the reduction in the use of detergents and
fresh water needed to clean the glass, The Building Research Establishment has indicated that
Pilkington ActivTM is actually more beneficial to the environment than normal glass. What’s more, it
also reduces maintenance costs.

Q. How do I know I have Pilkington ActivTM in my windows?

A. Pilkington ActivTM can be identified using a unique hand-held detector on the coated surface,
which your installer should have available. Your installer should also provide you with a Pilkington
ActivTM installation certificate.
