Choosing the right material for your outdoor decking is an essential step in creating a beautiful and functional outdoor living space. Two popular materials for decking are pressure-treated wood and wood composite. Both offer their unique set of advantages and disadvantages, which can make the decision-making process challenging. In this blog, we will discuss the differences between composite wood and pressure-treated wood, the benefits and downsides of each material, and help you make an informed decision for your outdoor decking project.

 

What’s the Difference Between Composite Wood and Pressure Treated Wood?

Composite wood is a man-made material, made from a mixture of wood fibres, plastics, and various other materials. This mixture is then heated and pressed into boards, creating a durable and low-maintenance product. Composite wood is designed to mimic the appearance of natural wood, with a variety of colours and textures available.

Pressure-treated wood, on the other hand, is a natural wood product that has been chemically treated to resist decay, insects, and fungal growth. This treatment helps to extend the life of the wood, making it suitable for outdoor use. Pressure-treated wood is typically less expensive than composite wood but requires regular maintenance, such as staining or sealing, to maintain its appearance and durability.

 

The Benefits of Composite Wood for Outdoor Decking

  • Low Maintenance: One of the most significant advantages of composite wood is its low maintenance requirements. Composite decking doesn’t need to be stained, sealed, or painted, and it resists fading, warping, and cracking. This means you can spend more time enjoying your outdoor space and less time maintaining it.
  • Durability: Composite decking is highly resistant to rot, insect damage, and fungal growth, making it a long-lasting option for your outdoor space. Additionally, its resistance to warping and cracking helps maintain a smooth, attractive surface.
  • Aesthetics: Composite wood is available in various colours and textures, allowing homeowners to choose a style that complements their home and landscaping. Many composite decking options closely resemble natural wood, providing a high-end look without the associated maintenance.
  • Environmental Friendliness: Many composite decking products are made from recycled materials, making them an eco-friendly choice for environmentally conscious homeowners.

 

The Downsides of Composite Wood for Outdoor Decking

  • Cost: One of the primary disadvantages of composite decking is its initial cost. Composite wood is generally more expensive upfront than pressure-treated wood. However, the reduced maintenance requirements and increased longevity can offset this cost over time.
  • Heat Retention: Composite decking can get hot under direct sunlight, which might make it uncomfortable to walk on during hot summer days. This issue can be mitigated by choosing lighter-coloured decking options.
  • Limited Repair Options: If a composite deck board becomes damaged, it often needs to be replaced entirely, as repairing composite materials can be challenging.

 

The Benefits of Pressure Treated Wood for Outdoor Decking

  • Cost-Effectiveness: Pressure-treated wood is generally more affordable upfront than composite decking, making it an attractive option for homeowners on a budget.
  • Natural Appearance: For homeowners who prefer the look and feel of real wood, pressure-treated wood offers an authentic, natural appearance that can’t be replicated by composite materials.
  • Versatility: Pressure-treated wood is a versatile material that can be cut, stained, and shaped to create a custom outdoor living space.

 

The Downsides of Pressure Treated Wood for Outdoor Decking

  • Maintenance: Pressure-treated wood requires regular maintenance, including staining or sealing, to maintain its appearance and protect it from the elements.
  • Chemical Concerns: The chemicals used in the pressure-treating process have raised concerns about potential health risks and environmental impact. However, newer, less toxic treatment options are available, and proper precautions can mitigate these risks.
  • Susceptibility to Weathering: Pressure-treated wood is more prone to warping, cracking, and splitting over time compared to composite decking. This can lead to an uneven surface and a less attractive appearance.
  • Shorter Lifespan: While pressure-treated wood is more durable than untreated wood, it generally has a shorter lifespan than composite decking. This means you may need to replace your deck more frequently, which could offset the initial cost savings.

 

Conclusion

Both pressure-treated wood and wood composite have their unique set of advantages and disadvantages when it comes to outdoor decking. When making your decision, it’s essential to consider factors such as initial cost, maintenance requirements, aesthetics, and longevity. Composite wood may be the right choice for those who prioritize low maintenance and durability, while pressure-treated wood could be a better option for those who prefer a natural appearance and lower upfront costs.

Ultimately, the best material for your outdoor decking project will depend on your preferences, budget, and long-term goals for your outdoor living space. By carefully considering the benefits and downsides of each material, you can make an informed decision that ensures you enjoy your outdoor deck for years to come.
