Traditional Composite decking, such as Trex, is a mixture of wood dust and plastic. It is extruded in a machine with lots of heat allowing the wood, plastic, coloring, and UV protectant to melt and mold together. This technology was first introduced to the decking industry in the 1990s. Today there are dozens of different brands of it available. The color selection has expanded considerably, but the technology has not changed much.
Composite decking is still a cost effective option in low-maintenance decking, and for the most part will outlast wood. It has however been surpassed in looks, durability, and user experience by PVC and PVC wrapped decking. Composite decking will soften over time with exposure to the elements, allowing things like dirt and algae to absorb into it, making it harder and harder to clean. Pvc decking will maintain it’s tight outer shell, making it much easier to maintain
Pros: Low maintenance, never needs painted or stained, no splinters, lower upfront cost
Cons: Durability concerns, needs cleaned regularly, color fading
