The Fiberon Concordia Astir Composite Fascia & Riser Board brings the same rustic cathedral grain and natural, multi-tonal woodgrain look of Astir decking to deck edges and stair risers, giving a cohesive, high-end appearance across the whole build. Finishing the perimeter of a deck or the front of a stair riser with a matching material eliminates the visual mismatch that comes from pairing composite decking with unfinished framing lumber underneath.
Built with the same four-sided PermaTech cap and composite core as Astir decking, these boards resist fading, staining, moisture, mold, and mildew, holding their color and appearance through repeated weather exposure. Like the decking, they require no sanding, staining, or sealing — a straightforward, low-maintenance option for finishing deck perimeters and stair fronts where durability and appearance both matter. Fascia boards measure 3/4" x 11-1/4" x 12', and matching riser boards measure 3/4" x 7-1/4" x 12'. Available in the same three Astir colors as the decking line — Prairie Wheat, Mountain Ash, and Seaside Mist — and compatible with Starborn Pro Plug and Deckfast Fascia System fasteners for a fully concealed installation.
