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 rain water to 'sheet' down the glass to wash the loosened dirt away.
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.
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.
The coating has been proven to last as long as the glass itself. The coating is permanent and will not need re-applying.
Yes. The coating contains harmless chemical substances already found in the home, in such things as bath oils and toothpaste. In fact, with only small amounts of cleaning agents needed, Pilkington Activ'" is kinder to the environment than normal glass.
Pilkington Activ'" can be identified using a unique hand-held detector on the coated surface, which your installer should have available.
Almost any exterior application, such as windows, conservatories, facades and glass roofs. It can be installed vertically or at an angle of at least 10 degrees, but ideally 30 degrees or more, and is especially useful for inaccessible windows where organic dirt normally collects, such as skylights. Avoid glazing with Pilkington Activ™ under an overhang or in a situation where daylight and/or rain cannot reach it. It has been designed for exterior use only.
Pilkington Activ1" can be combined with other Pilkington glass products in insulating glass units to provide benefits such as thermal insulation, noise reduction, solar control and fire protection. Additionally, Pilkington Activ'" is available in toughened or laminated form for increased safety and security. Also, Pilkington Activ'" Blue offers self-cleaning properties with solar control performance.
We cannot say that your windows will never need cleaning - that depends on the amount of dirt and the amount of rain the glass in your window receives. Pilkington Activ™ reduces the amount of maintenance required. If cleaning is necessary - such as during long dry spells or if your windows are heavily soiled - it will be much less frequent and much easier than with conventional glass, either by hosing with water to replicate rainfall or using a soft cloth and warm soapy water.
Pilkington Activ'" will remove organic deposits, such as fingerprints or tree sap, but it will not break down inorganic dirt. To remove inorganic dirt before the next rainfall, simply spray or hose the glass with water.
