Pilkington Activ™

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 - Pilkington Activ does just that.
Its unique dual-action uses the forces of nature to help keep the glass clear of 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 normal glass with a special coating 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.

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

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.
