Products made from TherraWood®. Are a unique blend of PVC, wood fiber and other proprietary components. The decking is an elegant, cost-effective, durable and safe alternative to wood, for both residential and commercial areas. The lifespan of wood is limited when exposed to harsh weather conditions and insect damage. Wooden decks require chemical treatments to maintain appearance and structural integrity. Screw heads pop out over time and required maintenance which generates extra cost and takes time away from your fun and relaxation. In addition, the safety of wooden structures can put friends and family at risk with splintered or slippery surfaces.
