PPG Industries Inc. said it has launched an initiative aimed at assisting metal-roof manufacturers in expediting registration of cool-roof coating colors with the Cool Roof Rating Council (CRRC) and EPA ENERGY STAR cool-roof program.
PPG said the initiative results from a modification made in the ENERGY STAR Cool Roof program, which now accepts products registered with CRRC under the council’s Color Family Program. Under the CRRC program, PPG said it can register a “representative” color in one of 17 standard color families, provided it has met CRRC’s prescribed three-year aged exposure criteria. New or additional colors within the same color family can be added to the CRRC registry without three-year test data, as long as they meet CRRC’s initial ratings criteria for solar reflectance (SRV), thermal emittance (TE), and color. PPG said it can then assist metal roofing manufacturers in registering these colors with CRRC and ENERGY STAR under their own company names.
PPG said it can accelerate dual color registration with CRRC and ENERGY STAR because it has registered representative color standards, including three-year test data, for all 17 CRRC color families in both polyvinylidene fluoride (PVDF) and siliconized polyester coatings technologies. The company’s Duranar ULTRA-Cool coatings are based on PVDF technology, and its Super II ULTRA-Cool coatings are made with siliconized polyester resins.
“Because we have completed testing and registration for all potential color families with CRRC, we are able to speed color registration with ENERGY STAR,” said Tom McKay, product manager for PPG coil and extrusion coatings.
PPG said it currently has 154 colors registered with CRRC; the full list can be viewed at the CRRC website, located at www.coolroofs.org. More information on the company’s cool-roof coatings can be obtained from the website located at www.ppgideascapes.com.
