Our aluminum cladding with the Pella EnduraClad® seven-step finish delivers a cladding system with excellent weatherability. Resists fading and will not crack Provides a beautiful, low-maintenance exterior Protects your design for years

The EnduraClad Plus finish takes our EnduraClad finish a step further featuring the superior weatherability of full-strength 70% Kynar 500/Hylar 5000 PVDF resin-based protection. Please note that only 70% PVDF resin provides ultimate weatherability protection and longer-lasting resistance to fading and chalking. Make sure that your specifications call for 70% Kynar 500/Hylar 5000 resin —not 50% PVDF resin—to ensure a significant increase in performance over our tough EnduraClad finish. Only 70% Kynar 500 finishes exceed the AAMA 2605 standards for exceptional weatherability.

Standard, Windowscaping®, and special custom colors are available. Consult manufacturer’s architectural representative and edit accordingly. Standard finish system is Pella EnduraClad™ baked-on polyester enamel. Pella EnduraClad™ Plus fluorocarbon-based (Kynar 500*) finish system also available. *Kynar and Kynar 500 are registered trademarks of Elf-Atochem North America, Inc.
