Composite decking is a popular alternative to traditional wood, offering durability, low maintenance, and an eco-friendly option for outdoor spaces. But what exactly is composite decking made of? This article will break down the materials and processes involved in creating composite boards, ensuring you have all the information you need to make an informed decision.
Primarily consists of a blend of wood fibers and plastic. These materials are often sourced from recycled content, making composite decking an environmentally responsible choice. The wood fibers provide a natural look and feel, while the plastic enhances strength and longevity.
Reclaimed sawdust, wood chips, and other wood by-products make up the wood flour that gives the decking its natural appearance and texture.
Manufacturers typically use polyethylene (PE), polypropylene (PP), or polyvinyl chloride (PVC) to add durability to the decking.
Various additives improve the decking’s performance and appearance:
Produced using two main processes: extrusion and compression molding.
In this process, the mixed materials (wood fibers, plastic, and additives) are heated until malleable. The mixture is then forced through a mold that shapes the decking boards.
Here, raw materials are placed into a mold, and pressure shapes the boards. This method often results in a more consistent texture and density.
Both processes ensure that the decking remains strong, durable, and resistant to common issues like warping, rotting, and insect damage.
When choosing composite decking, you’ll primarily find capped options. Capped decking includes a protective outer layer that surrounds the board, offering enhanced protection against the elements.
The protective cap shields the board from moisture, stains, fading, and scratches. This protection keeps the deck looking new for longer, even with minimal maintenance. Leading brands like Trex, TimberTech, and Fiberon offer capped composite options known for their durability.
This older technology lacks a protective cap, making it more vulnerable to damage from moisture, UV rays, and daily wear and tear. Without the cap, uncapped decking may require more frequent maintenance and show signs of wear sooner. Due to these limitations, most homeowners now prefer the enhanced durability of capped composite decking.
Offers several advantages over traditional wood:
You won’t need to stain, seal, or paint it. A quick clean with soap and water is usually all it takes to maintain its appearance.
Resists warping, splintering, and insect damage, making it a long-lasting option for outdoor spaces.
The protective cap on capped decking shields it from moisture and UV rays, ensuring a longer lifespan.
Made from recycled materials, supports sustainable living while delivering high performance.
So, what is composite decking made of? It’s a blend of wood fibers and plastic, enhanced with protective additives, and manufactured into durable, low-maintenance boards. Capped composite decking, offered by leading brands like Trex, TimberTech, and Fiberon, provides superior durability and protection, making it the ideal choice for long-lasting, beautiful outdoor spaces.
