Future Decking Materials Outlook
As reported by Research and Markets, the global wooden decking market is projected to reach $8.55 billion by 2025, while innovative materials like carbon-negative composite decking are emerging to address environmental concerns in the construction industry.
Carbon-Negative Composite Decking
Carbon-negative composite decking represents a groundbreaking advancement in sustainable construction materials. Developed by researchers at the Pacific Northwest National Laboratory (PNNL), this innovative decking material stores more carbon dioxide than is emitted during its production. The composite is made from low-quality brown coal or lignite fibers, modified with carbon dioxide to enhance their compatibility with plastics. This process results in a material that is not only environmentally friendly but also 16% cheaper than standard composite decking.
Key features of carbon-negative composite decking include:
- Sequesters 2.5% carbon dioxide by weight
- Meets international building codes for strength and durability
- Potential to sequester 230,000 tonnes of CO2 annually if widely adopted in the US market
- Expected commercial availability as early as summer 2025
- Versatility for use in other building materials like fencing and siding
This innovation represents a significant step towards reducing the construction industry’s carbon footprint while offering a cost-effective and durable alternative to traditional decking materials.
High-Performance Wood Alternatives
High-performance wood alternatives are gaining traction in the decking industry, offering superior durability and low maintenance compared to traditional wood. Composite decking, made from a blend of recycled plastic and wood fibers, has become a popular choice due to its resistance to rot, warping, and insect damage. PVC decking, composed entirely of synthetic materials, provides excellent moisture resistance and is ideal for waterfront properties.
These alternatives come in a variety of colors and textures that mimic natural wood grain, allowing homeowners to achieve the aesthetic of wood without the upkeep. Some composite and PVC decking options feature a protective polymer shell for enhanced stain and fade resistance. While these materials typically have higher upfront costs than traditional wood, their long-term durability and minimal maintenance requirements can offer better value over time.
PVC Decking Durability
PVC decking stands out for its exceptional durability, offering superior resistance to environmental factors compared to traditional wood and even composite alternatives. Made from 100% plastic, PVC decking is impervious to moisture, making it highly resistant to rot, mold, and warping. This material can withstand extreme temperature fluctuations without significant expansion or contraction, maintaining its stability in various climates.
Key durability features of PVC decking include:
- Resistance to fading, staining, and scratching due to advanced polymer technology
- Excellent performance in harsh UV exposure and prolonged sunlight
- Potential lifespan of over 50 years, outperforming composite decking
- Imperviousness to insect damage and decay
- Minimal maintenance requirements, typically only needing occasional cleaning
While PVC decking may have a higher upfront cost, its long-term durability and low maintenance needs often result in better value over time compared to other decking materials.
