Key Features

  • Low-e coating reflects heat back into the room, reducing heat loss
  • U g-values of 0.6 W/m²K when incorporated in triple glazing units
  • Intended to reduce external reflection when used in triple glazing units when compared to Pilkington Optitherm™ S1 Plus
  • Neutral view through glass due to high light transmission
  • Achieves Class C to EN 1096-3
  • Single stock product available in annealed form and can be toughened without compromising performance or appearance

 

Applications


Pilkington Optitherm™ S3 Plus is suitable for a wide range of residential and commercial projects where triple glazing units are required:

  • New-build housing/buildings
  • Replacement windows
  • Conservatories and garden rooms
  • Energy-efficient upgrades to existing homes

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.).
