Promenade has the look of handcrafted wood decking and the durability of premium PVC. It resists mold, splinters, and cracks, making it perfect for docks, marinas and other waterside use. It's tested and approved for use in fresh water, salt water, and chlorinated water environments, and is suitable for installations that may be submerged, like dock and pool stairs. In comparison to wood and PE boards, Promenade outperforms in terms of mold, water absorption, and discoloration, and meets all performance standards for San Diego County and ASTM E84 Class A.
