Crystal Window & Door Systems has upgraded the standard powder-coat paint finish on all its aluminum windows and doors. The new finish complies with the American Architectural Manufacturers Association (AAMA) Specification 2604: High Performance Organic Coatings on Aluminum Extrusions and Panels
. The no-cost upgrade represents a substantial improvement in value, since AAMA 2604 is an enhanced durability performance standard and a significant step up from typical aluminum window paint coatings. The AAMA 2604 standard requires applicators to test samples and prove durability in the critical areas of salt spray and humidity resistance, and retention of color and gloss.
