NyloBoard decking was described to us as a “noncomposite composite.” The resin is mixed with post-industrial carpet fiber rather than sawdust. Although the product is 80% carpet fiber by volume (20% by weight), the resin makes it impervious to water. It looks like capped decking but isn’t — the resin rises to the surface during the manufacturing process. Board edges can be grooved or square. The 1x6 boards come in lengths up to 24 feet and are rated for 200 pounds per square foot for a 16-inch span, 100 pounds for a 24-inch span. They cost $3.50 to $4 per linear foot.
