TwinFinish® Collection

This wood composite decking is great for use near water. It features a VertiGrain slip-resistant surface, making it the affordable choice for decking.

TwinFinish Decking offers many benefits for those seeking affordable decking with a slip-resistant surface:

  • Tough: Proprietary wood composite material; VertiGrain slip resistant surface on one side, serrated pattern on the other
  • Enduring: Stands up to harsh weather
  • Durable: Resists mold, mildew, and moisture damage
  • Beautiful: Texturized for a wood-like appearance
  • Low-maintenance: No annual sealing or staining required for protection
  • Protected: Comes with 30-year limited warranty in residential applications

Twin Finish®, Docksider™ and ReliaBoard® are covered by TimberTech’s 30-Year Limited Warranty but do not include separate fade and stain coverage. TwinFinish, ReliaBoard, and DockSider are designed to naturally weather over time and the surface grain pattern will weather to a more consistent color. Most of the weathering process will be complete within the first year of the deck’s life.
