Concordia premium PE composite decking combines classic and on-trend colors and grain patterns with unbeatable performance. Available in three distinct collections: Astir, Horizon, and Symmetry. The Astir Collection features a rustic cathedral grain and three fresh, nature-inspired multi-tonal hues. Durable composite core resists splintering, rotting, cracking, insects and decay. Four-sided PermaTech cap layer provides superior protection and fade resistance. Boards never need sanding, staining or painting. Simply clean with soap and water or a mild cleaner. Finished surface on top and bottom is ideal for second-story decks, and reversible boards save time and money while reducing waste.
