The primary purpose for utilizing coatings with solar reflective properties is to keep the coated surfaces cooler than they would be with standard coatings.
“Since its development, cool coatings technologies have always been thought of as being strictly for roof coatings. As is the case with roofs, such coatings can be beneficial on the façade as well as window frames, railings, outdoor equipment enclosures and numerous other applications as recent studies have shown,” said Manny Mayer (TIGER Drylac U.S.A., Inc.), chair of AAMA’s Cool Coatings Task Group. “In order to specify such coatings for alternate purposes, AAMA’s Cool Coatings Task Group felt there was a need in the market place to provide a specification for manufacturers and architects to help in the evaluation and selection process of the best coating for the project.”
Carl Troiano (Trojan Powder Coating Co.), vice chair of AAMA’s Cool Coatings Task Group, added, “In order to continually meet the reduction of energy usage, AAMA 643 will help implement cool coatings technology of future projects and will be eventually used in LEED® programs.”
Additionally, AAMA 643 is intended to assist the architect, owner and contractor to specify and obtain factory-applied finishes that will provide higher than standard Total Solar Reflectance values and still maintain a high level of performance in terms of film integrity, exterior durability and general appearance over a period of many years.
