Get great results and the best value with SLS Capped Composite Decking. This superior composite outperforms standard wood plastic composite boards when it comes to installation and long-term beauty.

SLS Composite is not the same as run-of-the-mill composite decking. SLS composite is a high-performance blend of polypropylene and inorganic fillers. With no wood content, it absorbs virtually no water. SLS boards won’t expand and contract because of moisture. And, they don’t get too hot on sunny days.

Capped on 4 sides for extra protection and durability. A tough outer layer protects boards from wear and weather. Resists scratches, a plus when you’re busy building. No-fade, easy-clean surface resists stains.

10-year warranty against defects resulting in splintering, rotting, termite damage, and fungal decay. 10-year warranty against fading & staining.

Overall very good quality dollar for dollar! I was expecting this product be double sided based on phone interaction with an agent and photos provided on the listing. Unfortunately, it’s not so using it as a deck + privacy fence as shown in the photos was not easily done. There is black product labeling on the underside, so to appease the HOA I needed to find a paint match the color to and paint over the bottom-side so you can’t see the writing. It would have been great if it were like the photos with grain line effect on both sides, not sure what happens there? Never heard back from the service rep on my issues there. But, it took a while to get photos to her as we built during the winter so we had numerous weather delays. The sale price still made it a great deal. Only negative that I found was that light Frost is slick on these boards but it doesn’t take much to warm up. Snow and ice doesn’t last long and traction was better than expected. Additionally, they don’t have that glare effect that heats up quickly (some composite boards have it as part of the finish) so these don’t get crazy hot in the sun. All around good quality, extremely durable and tough against drops and don’t scratch during construction so you don’t have to be overly cautious with them while building.
