AZEK® Cladding


AZEK Cladding delivers the full aesthetic experience of wood without the laborious, costly, and constant upkeep required with traditional lumber. Our one-of-a-kind capped polymer boards achieve a realistic wood look that lasts—that’s why we back them with industry-leading warranties for both commercial and residential buildings. AZEK® Capped Polymer Cladding offers a wide range of color options, multiple board widths and offers both tongue-and-groove (closed-joint) and square shoulder boards (open-joint). With AZEK Cladding, you lock in exclusive application options for your uniquely beautiful design.


AZEK square shoulder boards installed with small gaps (open-joints) between each board creates a cladding rainscreen. The open-joints between the cladding elements create a strong, linear design pattern while also functionally providing air flow to promote ventilation.

Install AZEK tongue-and-groove cladding boards that interlock together with ease as another cladding design option. The closed-joint finished look has a more subtle linear design with a smoother finish compared to the larger gaps of the open-joint aesthetic.
