The update was made as a clarification to the requirements for outdoor or accelerated weathering testing.
The document, "Voluntary Specification, Performance Requirements and Test Procedures for Solar Reflective Finishes," was originally released in 2013.
"Advances in coatings technologies for architectural products have provided the opportunity to expand the use of solar reflective coatings," says Manny Mayer, architectural products manager at Tiger Drylac.
"Selecting high-performance coatings with these solar reflective attributes can positively impact the energy efficiency associated with all exterior coated building components. The primary purpose for utilizing coatings with solar reflective properties is to keep the coated surfaces cooler than they would be with standard coatings."
This specification is a supplement to the existing specifications (AAMA 613, 614, 615, 623, 624, 625, 653, 2603, 2604 and 2605) aned does not in any way supersede the performance requirements contained in those documents, particularly the weathering requirements.
