F.	Exterior:
Specifier Notes:  AAMA 2603, 2604, and 2605 are the most commonly referenced exterior finish quality standards for painted aluminum.  Pella aluminum-clad products are offered with two quality levels of paint finish, “EnduraClad” and “EnduraClad Plus”.  Pella “EnduraClad” finish meets or exceeds all AAMA 2604 requirements, which possesses the distinguishing characteristic of an elevated resistance to abrasion and corrosion.  Pella “EnduraClad Plus” finish meets or exceeds all AAMA 2605 requirements, which possesses the distinguishing characteristic of an elevated resistance to fade.  This quality makes “EnduraClad Plus” an excellent choice for deeper, more fade-prone color selections in areas of high UV exposure.
Pella “EnduraClad” and “EnduraClad Plus” exterior finish systems are also tested to the following ASTM G 85 test method.  Consult Pella for warranty options for seacoast applications.
