Pilkington Activ™ Clear


Pilkington Activ™ Clear is a UK-manufactured, on-line coated, self-cleaning glass intended to give householders low-maintenance clean windows.

Based on a Pilkington UK invention, the invisible coating works in two stages:

How it works

The coating has photo-catalytic and hydrophilic properties:

Stage 1 (photo-catalytic) - The coating reacts with natural daylight to break down and loosen organic dirt.

Stage 2 (hydrophilic) - When it rains, instead of forming droplets, the water is attracted to the coating and spreads evenly over the surface of the glass, helping to wash away any dirt and reduce streaking.

During long dry spells the glass can be cleaned by simply hosing it down with clean water.

Pilkington Spectrum

Pilkington Spectrum is a Windows-based glass performance model which enables you to quickly and efficiently calculate key properties of a wide range of single glazing and insulating glass units. Also available as an app for mobile devices, you can use Pilkington Spectrum to provide the following information:

  • Light and solar properties (transmittance, reflectance, absorptance, g value, etc.).
  • Centre pane Ug-value.
  • Sound insulation values.
  • Global Warming Potential (GWP), or carbon footprint.
  • Ultra violet (uv) transmittance and colour rendering index (Ra).
  • Other properties (e.g. pendulum body impact resistance, fire resistance, resistance to manual attack, etc.).
