EN 1096-5 tests and classifies the self-cleaning performance of coated glass. It is the only independent assessment that can verify the performance of products that use hydrophilic and photocatalytic properties to enhance the cleanliness of the glass.
Pilkington Activ™, which this year celebrates its 15th anniversary, uses a microscopic coating with a dual action. Firstly, the coating is activated by daylight to break down organic deposits such as dirt and then, when rainwater hits the glass, the coating allows the water to spread evenly and run off in a ‘sheet’ – removing any dirt at the same time.
Independently tested by the Fraunhofer Institute for Surface Engineering and Thin Films (IST) in Germany, this result further validates the performance of Pilkington Activ™, which has previously achieved Class A, the highest classification for coating durability in accordance with EN 1096-2. This standard tests the durability of a coating to natural weathering conditions, as well as abrasion.
Alessandro Michetti, European Commercial & Marketing Director at NSG Group, said: “We’re seeing increased demand across both the commercial and domestic markets for self-cleaning glass as occupiers and homeowners look for products that help cater to modern life. As the pioneers of self-cleaning glass it’s important that we continue to invest in and develop our product range to ensure it remains best in class.
“Not only will this standard provide peace of mind for homeowners, who can insist on installers supplying self-cleaning glass that passes this latest test, it will also enable specifiers to differentiate between products with an official self-cleaning performance and those without.
“Pilkington Activ™ helps to reduce the amount of time and money spent on window cleaning, while providing clearer, better-looking windows, and this latest achievement is testament to the quality and strength of our offering.”
