Since its launch in September 2022, the Cool Roof Rating Council (CRRC) has issued third-party product ratings for more than 100 exterior paint and siding products on the CRRC Rated Wall Products Directory (Wall Directory). As of July 30, 2024, there are 111 rated products spanning seven manufacturers and two product categories: architectural coatings and metal siding.
CRRC Wall Product Ratings are obtained through participation in the CRRC Wall Product Rating Program. The CRRC began accepting Wall Product Rating applications in January 2022 after years of development by experts. The program is overseen by the CRRC Wall Rating Program Committee.
The Wall Directory provides verified ratings of products’ solar reflectance and thermal emittance, informing design professionals and consumers about a product’s ability to reflect solar energy away from a building and cool itself by radiating absorbed heat. These properties improve resilience to heat, mitigate the urban heat island effect, and reduce cooling energy use. Exterior “cool” walls are promoted by standards, energy and building codes, and programs such as LEED.
