What Is Composite Decking Material? Everything You Need to Know

Why Composite Decking Is Reshaping Outdoor Design?

Outdoor spaces are an essential part of modern architecture. From cozy rooftop lounges to expansive terrace decks, demand for beautiful, durable, and low-maintenance surfaces is on the rise.

While traditional wood was once the go‑to, concerns about maintenance, weathering, and environmental impact led professionals to look for better alternatives. Composite decking delivers on all fronts, combining the warmth of wood with enhanced durability and practical benefits.

In this guide, you’ll learn what composite decking is, understand the key terms professionals use, explore the types available, and find out how it suits both residential and commercial projects. Let’s build that foundation of knowledge.

Key Takeaways

✓ Composite decking combines recycled or bio-based materials to provide boards that are durable, moisture-resistant, and low-upkeep. This makes it a practical choice for architects and developers aiming for long-term performance.

✓ Understanding key decking terminology, such as profiles, span ratings, and fastening methods, ensures accurate specifications. It also helps in aligning material choice with project requirements and industry standards.

✓ Different composite types like wood-plastic, fully synthetic, and bio-based offer unique benefits in aesthetics, strength, and sustainability. Selecting the right type depends on project scale, environment, and design goals.

✓ Resysta’s wood-free, bio-based, composite decking merges a sustainable source with architectural versatility. It delivers the warmth of wood without the ongoing maintenance or environmental drawbacks.

Core Definitions and Common Terminologies in Decking

Before diving into the types and benefits, it’s important to understand the language of decking. Knowing these terms helps professionals specify the right materials and ensure code compliance, and also helps homeowners make informed choices for their projects.

• Composite Decking – An engineered board made from a blend of wood fibers, plastics, or alternative binders. Designed to mimic the appearance of wood but with enhanced durability.

• • Capstock / Capped Composite – Decking with a protective polymer shell around the core to resist fading, staining, and moisture.
  • WPC (Wood-Plastic Composite) – A mix of recycled wood flour and plastic. Strong, versatile, and widely used in residential decks.
  • PVC Decking – Made entirely from polyvinyl chloride (plastic) with no organic content. Often lighter, but not technically a composite.
  • Profiles – The shape of the board’s cross-section. Includes:
    • Solid: Fully dense and heavy-duty.
    • Grooved: Designed for hidden fasteners.
    • Tongue-and-Groove: Boards interlock for a seamless look.
    • Scalloped: Hollowed underside to reduce weight.

• Deck Board Fastening
• • Hidden Fasteners: Clips or brackets that secure boards without visible screws.
  • Face Screws: Traditional fastening method where screws are driven into the board’s surface.
• Span Ratings – The maximum distance a board can span between supports without bending.
• Fascia & Riser Boards – Trim boards used for finishing edges and covering stair risers.

For more technical definitions, refer to the American Wood Council for recognized industry standards.

Types of Composite Decking Materials on the Market

Not all composite decking is the same. The composition impacts weight, durability, sustainability, and aesthetics.

Wood-Plastic Composites (WPC)

• A blend of wood fibers and recycled plastics.
• Offers the look of wood with reduced upkeep.
• Common in residential projects and moderately priced.
• Drawback: Can be heavier and more prone to surface scratching compared to other options.

Fully Synthetic Composites

• Made without organic material, no wood fibers.
• Excellent resistance to moisture, insects, and rot.
• Often lighter due to hollow-core construction.
• Drawback: May lack the natural grain variation and warmth of wood-based composites.

Bio-Based Composite Decking

• Uses rice husks, bamboo, or agricultural waste.
• Lower carbon footprint and highly sustainable.
• Mimics the look and texture of real wood.
• Resysta Building Products USA offers a wood-free, rice husk-based composite that is moisture-resistant, dimensionally stable, and LEED-compliant, ideal for projects where performance and environmental responsibility matter.

Benefits of Using Bio-Based Composite Decking

1. Durability – Composite boards won’t splinter, crack, or warp like natural wood, making them ideal for heavy use.
2. Moisture Resistance – Perfect for pool surrounds, coastal homes, and humid climates. Bio-based composites like Resysta resist water absorption.
3. Low Maintenance – No sanding, staining, or sealing is required. Occasional cleaning is all it needs.
4. Design Variety – Available in multiple colors, grain patterns, and finishes, allowing flexibility in design.
5. Sustainability – Many composites use recycled materials. Bio-based products reduce the need for virgin timber, helping preserve forests. According to the U.S. Green Building Council, using sustainable materials can contribute toward LEED certification points.
6. Cost Efficiency Over Time – While the initial investment is higher than traditional wood, lower maintenance and longer lifespan make it cost-effective over the decades.
7. Thermal and Energy Performance – According to the U.S. Department of Energy, material choice can influence surface heat retention, improving comfort in outdoor spaces.

A Smart Investment in Design and Durability

Natural or bio-based composite decking has evolved into a high-performance, low-maintenance, and sustainable choice for architects, developers, and builders. With multiple material options, customizable aesthetics, and proven durability, it outperforms traditional wood in both lifespan and cost efficiency.
