Pilkington Suncool™ Pro T

Pilkington Suncool™ Pro T is a range of UK-manufactured, off-line coated, solar control and low-emissivity (low-e) glass, chosen by UK specifiers to limit solar heat gain (heat from the sun) in buildings through glass.

‘Pro T’ is the standard format in the UK and means the glass must be toughened to achieve performance potential.

We manufacture Pilkington Suncool™ Pro T on our state-of-the-art coater in St Helens, Merseyside offering the latest products and improved sustainability to the UK construction market.

Intended to meet the demands of modern UK buildings, it supports compliance with energy regulations and helps homeowners reduce heating costs—without compromising on clarity.

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.).
