A CRRC product rating describes the radiative performance of an exterior wall material; it does not indicate a ranking or approval. A product’s placement on the Rated Wall Products Directory (Directory) does not mean that the product is “cool” as defined by any particular code or program. Only products with active ratings can be found on the Directory.
CRRC product ratings are determined for a fixed set of conditions and may not be appropriate for determining seasonal energy performance. The actual effect of solar reflectance and thermal emittance on building performance may vary. The manufacturer of each product stipulates that these ratings were determined in accordance with the applicable CRRC procedures.
A letter (e.g. “a”) at the end of a CRRC ID indicates that a product has been retested or reformulated, and new rated product values have replaced the original values.
