Self Cleaning glass is a relatively new product which was invented by Pilkington glass. It is frequently used on sloping patent glazing areas which are difficult to reach or do not benefit from a regular cleaning schedule. The performance of the permanent self cleaning coating will not diminish over time which gives an advantage over other spray coatings available which may need re-applying after five years.
glass is available in a clear format as well as being offered with solar control properties to reduce solar heating within the occupied space of the building.
The Activ Product Range
Pilkington Activ™ Clear is a self-cleaning glass with advanced dual-action for superior results.
The Self-Cleaning Process
Pilkington Activ's unique dual-action coating 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 glass.
Using a "photocatalytic" process, the coating on Pilkington Activ™ Clear reacts with ultra-violet rays present in natural daylight to break down and disintegrate organic dirt. The second stage occurs when rainwater hits the glass. Pilkington Activ™ Clear is "hydrophilic" which means that instead of forming droplets, the water spreads evenly over the surface and as it runs off takes the dirt with it. Compared with conventional glass, the water also dries off very quickly without leaving unsightly drying spots.

Pilkington Activ™ Clear
This product is effectively the same as conventional glass but with a specially developed coating on the outside that has a unique dual action. Once exposed to daylight, the coating chemically reacts in two ways. Firstly, it breaks down any ‘organic’ dirt deposits – such as bird droppings and tree sap – and secondly, rainwater ‘sheets’ down the glass to wash the loosened dirt away.
