Pilkington Activ™

The clean pane for easy-care glazing.

Product

With Pilkington Activ™ water drop marks are a thing of the past – and also the frequent cleaning of the outer glass surfaces. Pilkington Activ™ is the first glass worldwide with the dual-active self-cleaning effect. It only needs UV light and rain.

The special Activ™ glass surface on the outer side reacts with the UV rays and disintegrates organic dirt deposits – and will simply be washed off by the next rainfall.

In particular architects, façade engineers, contractors and facility managers are delighted with the possibilities offered by this glass. Our new brochure for architects explores the diversification, the possible combinations and the profitability of this product. (This brochure is available in German only. In case of interest, you'll find it for download on our German website.)

High efficiency – tested and approved.

Functioning

Pilkington Activ™ takes advantage of the nature on two counts in order to achieve its unique cleaning effect:

Photocatalytic effect (active oxygen): First, the Activ™ glass surface absorbs the ultraviolet sun rays causing a chemical reaction in the compound with oxygen: organic dirt particles are disintegrated and removed.

Hydrophilic effect (water film): The next rainfall guarantees the ultimate ‘cleaning effect’. Based on the hydrophilic properties of the Activ™ glass surface, the water forms an evenly spread film instead of forming drops and washes the partially dissolved dirt off.

Clean: In contrast to conventional glass, on Pilkington Activ™ water dries very quickly without leaving drop marks. The result: a clean pane.

Questions and answers

Does Pilkington Activ™ operate immediately?
Once mounted, the glass surface needs approximately five days to activate the self-cleaning function.

Can the self-cleaning process of Pilkington Activ™ be impaired?
If the self-cleaning process is stopped by a conventional cleaning it always self-activates after a few days. Leaves of other heavy soiling on the glass surface must be removed immediately. Pilkington Activ™ then needs approximately five days to accumulate new energy and to reactivate the self-cleaning process.

How long does Pilkington Activ™ operate?
Tests have proved that the self-cleaning function of the Activ™ glass surface provides as high a service life as standard insulation glass types – under normal circumstances and considering all handling guidelines.

Does Pilkington Activ™ operate even if it is cloudy and at night?
Once activated, Pilkington Activ™ operates round the clock. Due to the fact that the special glass surface needs only little UV-light and also accumulates this energy, the self-cleaning process continues operating even under heavy clouds or at night.

Where and how can Pilkington Activ™ be applied?
Both vertically and inclined, for nearly all kind of exterior use – such as windows, facades, winter gardens and glass roofs.

Can Pilkington Activ™ be combined with other function glass types?
Pilkington Activ™ can be combined with the whole range of Flachglas MarkenKreis products in order to optimise thermal insulation, sound insulation, burglary prevention or solar control.

Does glazing with Pilkington Activ™ ever need to be cleaned again?
Yes. Although the self-cleaning function of Pilkington Activ™ extends the cleaning intervals considerably, the cleaning does not at all become unnecessary. An additional cleaning is reasonable after longer periods without rainfall or in case of heavy soiling. In general, this cleaning is needed less and is far more uncomplicated than it would be for conventional glass. Normally, a simple washing off with water is enough, but you may also use a soft cloth and warm soapsuds. Special cleaning agents or drying are unnecessary.

Is Pilkington Activ™ also effective in case of heavy soiling (e.g. bird droppings)?
The Activ™ glass surface also disintegrates little by little heavy organic dirt deposits. If the UV-rays do not reach the glass anymore due to extreme dirt, the self-cleaning effect cannot reactivate. In this case, you should clean the glass with warm soapsuds using a soft cloth. Only a few days later, the Activ™ function reactivates again.

What are the effects of the special Activ™ surface on the appearance ot the glass?
The most important effect: the glass keeps clean for a longer period! From a certain angle, it shows a slightly greater reflecting effect with a light tinge. The glass thickness remains unchanged.

Is Pilkington Activ™ eco-friendly?
The composition of the Activ™ glass surface is completely inoffensive. What's more: Pilkington Activ™ saves many litres of cleaning water and cleaning agents and is, therefore, in a strict sense more eco-friendly than it is conventional glass.
