NSG Group made a significant step in the glass industry with the development of Pilkington Activ™, the first dual-action self-cleaning glass. The unique dual-action of the Pilkington Activ™ coating uses the forces of nature to help keep the glass free from dirt, giving not only the practical benefit of less cleaning, but also clearer, better-looking windows.
How it works
The unique dual-action self-cleaning coating is located on the external glass pane.
It has got photo-catalytic and hydrophilic properties, and works in two stages:
- (Stage 1) The coating reacts with natural daylight to break down and loosen organic dirt
- (Stage 2) When it rains, instead of forming droplets, the water spreads evenly over the surface of the glass, forming a thin film and helping to wash away any dirt and reduce streaks.
During long dry spells the glass can be cleaned by simply hosing it down with clean water.
The Pilkington Activ™ range includes products which benefit from both self-cleaning and solar control properties helping to create an environment that can be used all year round.
Furthermore Pilkington Activ™ is available in combination with other products from the Pilkington range to provide additional benefits such as impact resistance or increased security, noise control, thermal insulation, etc.
