Our Cool-Roof™ pavers utilize a high reflective value and low emissivity rate resulting in a high Solar Reflectance Index (SRI) value; Tile Tech Cool-Roof™ pavers have a minimum SRI value of 78. This high SRI value allows you to meet the needs for LEED certified projects when used on your roof and balconies and can also be installed on pedestals for a complete roofing system.
