NyloBoard’s NyloDeck decking, rated to span 24 inches o.c., and NyloPorch beaded porch flooring are both made from 100% recycled carpet. The strong, lightweight composite material is reportedly impervious to moisture, mold, mildew, and insects. The maker also claims it’s one of the most dimensionally stable boards available, having passed thermocycling tests that show less than 1/8-inch movement in a 20-foot board over a 100°F temperature swing. The company also makes NyloSheet—a panel of the same material that can be used in wet-location or heavy-exposure applications. nyloboard.com
