LOWELL, MA – The Cool Roof Rating Council’s (CRRC) Product Rating Program has rated Nygra Coatings’ Nygra Flex White Coating as having a solar reflectance index (SRI) of 109, among the top in the industry.
“This rating of our new formulation ranks Nygra’s white cool coating among the best of class,” said Sean O’Brien, Senior Vice President of Nygra Coatings. “While hot climates are particularly impacted by building heat, it is a critical issue everywhere, leading to increased air conditioning usage and costs. Our paints effectively address this problem by dramatically reducing building temperatures and the need for air conditioning while lowering the overall environmental impact.”
The company also announced the availability of a breakthrough line of black cool coatings. Also certified by the CRRC, Nygra’s black coatings are among the best performing black cool paints. These coatings are also available in both Rigid and Flex formulations to meet the needs of different roof surfaces.
“Producing a cool paint in black is a revolutionary breakthrough because traditional black roofs significantly increase building temperatures,” O’Brien added. “Unlike traditional bright white solutions on the market, our product does not reflect damaging heat onto neighboring buildings. Because they don’t produce glare — a significant problem around airports — Nygra’s black coatings provide a solution for those locations where white coatings are not an option.”
Nygra’s coatings also offer several significant advantages. Whether black, white or other colors, they are 80% thinner than standard cool paints and last 75% longer, reducing building heat by up to 40%.
The cool paints are rated based on the initial radiative property ratings (solar reflectance, thermal emittance and SRI). The CRRC rates various roof surface products with radiative property values rated under a strict testing program administered by the CRRC. A high SRI indicates that the material has a lower probability to become hot when exposed to sunlight.
CRRC testing demonstrated that Nygra Flex White has an initial solar reflectance of 0.86 and Emittance of 0.90 for a calculated SRI score of 109.
Based in Lowell, Massachusetts, Nygra Coatings is a pioneer of heat-reflecting paints for commercial buildings and commercial surfaces.
