PVC costs more upfront. Composite has a wood core that can absorb moisture if the cap layer fails. Both matter \u2014 but neither tells you which one belongs on your next job.<\/p>\n\n\n\n

Australian builders face a real fork here. Fire compliance zones, coastal UV exposure, and client budgets all pull in different directions. The right call depends on your project type, not just the price per board.<\/p>\n\n\n\n

This guide compares composite and PVC decking on what actually moves the needle: fire ratings, UV and weather performance, slip resistance, long-term upkeep, cost, and supply reliability. We’ll call out where each material wins \u2014 and where it doesn’t.<\/p>\n\n\n\n

What Is Composite Decking Made Of?<\/h2>\n\n\n\n

Composite boards blend wood fibre and recycled HDPE plastic into boards that look and feel close to natural timber. A co-extruded cap layer wraps the core \u2014 blocking UV rays, moisture, and surface wear.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

LastElegance composite boards use 60% recycled content. HDPE density sits at 0.95 g\/cm\u00b3. The cap layer is 0.8 mm thick, which is on the thicker end compared to most products on the market. That extra cap thickness is what drives UV protection and colour retention over time.<\/p>\n\n\n\n

The wood fibre gives boards their weight, rigidity, and warm underfoot feel. The HDPE binds it, seals it, and keeps moisture out.<\/p>\n\n\n\n

What Is PVC Decking Made Of?<\/h2>\n\n\n\n

PVC decking is 100% polyvinyl chloride \u2014 no wood fibre, no organic content. It’s a synthetic board shaped to mimic timber. Because there’s nothing organic inside, PVC boards can’t rot, swell, or feed insects.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

The trade-off is clear. Maximum moisture resistance. But a feel and look that doesn’t match natural timber \u2014 especially underfoot. For some projects, that’s fine. For others, it’s the deciding factor.<\/p>\n\n\n\n

How Do They Look and Feel?<\/h2>\n\n\n\n

On appearance, composite decking wins clearly. Wood grain patterns are pressed into the surface. Boards come in a wide colour range. The feel underfoot is warmer than solid plastic \u2014 and for most clients, that’s what they’re asking for.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

PVC boards have improved over the years. But for projects where a natural wood feel matters \u2014 residential developments, resort-style outdoor areas, landscaping jobs \u2014 composite is the stronger pick.<\/p>\n\n\n\n
