Pilkington Optitherm™ Range


The Pilkington Optitherm™ Range are high performance, off-line coated low-e glass products specially developed for use in Insulating Glass Units (IGUs) to help with energy saving. They are optimised for thermal insulation having ultra low Ug values and are super neutral in colour.

The range includes: Pilkington Optitherm™ S3 and Pilkington Optitherm™ S1A.

The Pilkington Optitherm™ Range can also be combined with other glass products from our range to provide additional benefits such as safety, security, noise control, self-cleaning and solar control.

Spectrum Calculation Program

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.).
