For over a decade, NEXXFIELD has been using our unique, USPTO-registered Silver Grey material on our shockpad systems. This material creates the best possible compromise between a good S.R.I. (solar reflectance index) for dimensional stability during installation, and minimal visual reflection to decreases “blindness” often cited by installers when working with white material.
Solar Reflectance Index
The Solar Reflectance Index (S.R.I.) is a measure of the solar reflectance and emissivity of materials, which can be used as an indicator of how hot they are likely to become when solar radiation hits their surface. The lower the SRI, the hotter a material is likely to become in the sun.
SRI is measured on a scale from 0 to 100, where materials that absorb and retain solar radiation (and become hotter in the sun) have a lower number, while highly reflective materials (which remain cooler) have a higher number.
The measurements range from standard black (reflectance 0.05, emittance 0.90) set at 0 to standard white (reflectance 0.80, emittance 0.90) set at 100.
