What is Composite Decking?

Composite decking is a popular alternative to traditional wood decking and closely mimics the look and grain of real wood without high maintenance. It feels smooth to the touch and keeps its good looks with minimal upkeep. This decking is made from a blend of wood fibres and recycled plastics or uPVC, combining durability with a low-maintenance surface and making it a favourite among many homeowners.

Composite Decking vs. Wood Decking

Wondering whether to choose composite decking over natural timber? Here are the key benefits:

• Low-Maintenance: Traditional wood decks need regular sanding and refinishing, but composite decking only requires an occasional pressure wash.
• Aesthetic Appeal: Composite decking can match the beauty of wood decking and doesn’t fade as quickly.
• Durability: Made from plastic and wood pulp, composite decks are strong, although they generally don’t last as long as harder woods like Tallowwood or Ironbark.
• Resistance: It’s scratch, stain, and mould-resistant due to its manufacturing process. Although susceptible to some staining from oils, it’s generally robust against common deck wear and tear.
• Water and Fire Resistance: Most composite decks are completely water-resistant, making them ideal near pools or in gardens, and many options are fire-resistant, suitable for bushfire-prone areas.

Composite decking is also eco-friendly, often made from recycled materials, which reduces the need for virgin plastics and logging.
