Solar reflective index roofing

WebThe Solar Reflectance Index, or SRI, is a calculation using the aged solar reflectance and thermal emittance measurements of the asphalt shingles materials. It ranges from 0 to 100. This measurement can be used as an indicator of how hot shingles are likely to become … WebSolar Reflectance Index measures this crucial element on a scale of 0 to 100. Materials that absorb and retain solar radiation (and thus become hotter in direct sunlight) have a lower number, while highly reflective materials (which remain cooler in direct sunlight) have a higher number. Please note: Not every surface needs a high SRI.

SRI (Solar Reflective Index) measures a roof’s ability to reject solar heat (reflectance) and the ability to emit heat out (emittance). Cool roofs reflect and emit the sun heat instead of absorbing it. A cool roof is one that reflects the sun’s heat and emits absorbed radiation back into the atmosphere. grand lodge crested butte front desk
