Key Features

 

  • Lower solar heat absorption compared to the glass coated on standard clear float glass, therefore it reduce the risk of thermal breakage.
  • Varied range of solar control and light transmittance options available.
  • Solar radiation transmittance (g-value) ranging from 0.45 down to 0.19.
  • External light reflections ranging from a low 10% up to 26%.
  • Light transmittance performance ranging from 75% to 30% giving excellent light/heat ratios.
  • Ideal for large areas of glazing to control solar gain whilst providing high light levels.
  • Cost effective solution for reducing energy consumption.
  • Pilkington Suncool™ OW can be supplied in toughened, toughenable and laminated forms

Applications


Pilkington Suncool™ OW is suitable for a wide range of residential and commercial projects:

  • New-build housing/buildings.
  • Commercial high-rise buildings.
  • South-facing glazing susceptible to overheating.
  • Glazed extensions, conservatories and garden rooms.

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.).
