What is SRI?

Solar Reflectance Index combines two surface properties: solar reflectance (how much solar energy is reflected) and thermal emittance (how effectively absorbed heat is released.) A higher SRI generally indicates a surface that stays cooler in sunlight.

A Cooler Roof Can Support a Better Building

One roof coating system can protect the asset while supporting energy, comfort and sustainability objectives.

Where the greatest benefit is likely

  • Large exposed roof areas. Warehouses, distribution centres, factories, retail units and other low-rise industrial buildings.
  • High summer heat gain. Sites with dark roofs, direct solar exposure, limited shading or heat-sensitive internal operations.
  • Mechanical cooling. The financial opportunity is usually stronger where air-conditioning operates for long daytime periods.
  • Planned roof refurbishment. Solar-reflective performance can be considered alongside roof protection and waterproofing requirements.
