Building a deck is a project that promises a lot: an outdoor space to relax, entertain, or enjoy a lazy weekend morning. Transforming your outdoor space with a durable, low-maintenance composite decking is a smart investment. But choosing the right materials can feel overwhelming. This comprehensive guide provides an in-depth look at the benefits, costs, and top brands of composite decking, equipping you with the knowledge needed to make an informed decision and achieve a high-quality, enduring outdoor space.
What Are Composite Decking Boards?
Composite decking boards are a mix of wood fibres and plastic. This combination creates a material that mimics the look of natural timber but offers improved durability and lower maintenance requirements. Unlike traditional wood, composite decking resists rot, splintering, and fading, making it ideal for outdoor use.
You might also hear them called composite decking or composite deck boards. The construction involves a core material topped with a protective layer that maintains its appearance over time.
Advantages of Composite Decking
There’s a reason why more homeowners are switching to composite decking. Here are some of the big reasons:
- Low Maintenance: No need for staining, sealing, or sanding. Only regular cleaning with soap and water keeps it looking new.
- Durability: It’s resistant to rot, mould, and insect damage. It can handle harsh weather without warping or cracking.
- Appearance: Modern composite decking looks quite realistic, mimicking wood grain and texture.
- Longevity: Proven to last many years, decks can go 25+ years with minimal issues.
- Eco-Friendly Options: Many brands use recycled materials, making it a greener choice.
During the hot Australian summers, composite decking stays cool underfoot, unlike some traditional woods that get scorching. It’s a small thing, but it makes a difference when you’re barefoot.
Disadvantages to Consider
It’s not all sunshine and rainbows. Some drawbacks include:
- Initial Cost: The composite decking cost can be higher upfront than traditional timber.
- Appearance: While many options look good, some purists argue that it doesn’t have the same “warmth” as real wood.
- Installation Challenges: It can be tricky if you don’t follow proper procedures. It’s not as forgiving as wood in cutting and fitting.
- Heat Retention: In direct sunlight, composite boards can absorb heat, making them somewhat uncomfortable underfoot on hot days.
Cost of Composite Decking in Australia
When budgeting for a new deck, understanding the composite decking cost is crucial. In Australia, the price varies depending on brand, quality, and design, but it falls between $70 and $150 per square metre.
Compared to hardwood or treated timber, which might cost around $50-$80 per square metre, composite decks are more expensive. Considering the long-term savings on maintenance and replacement, many find them economical in the long run.
For example, if you’re covering a 20m² space, expect to spend roughly $1,400 to $3,000 for the material alone. Installation costs add another $500 to $100, depending on complexity and whether you hire professionals.
Installation Guide for Composite Decking
Proper composite decking installation is key to getting the most out of your investment. Here are some quick tips:
- Plan Your Layout: Measure carefully and decide on the direction of the boards. Many prefer running them parallel to the house.
- Prepare the Substrate: Ensure the foundation is level and solid. Most use concrete or timber supports.
- Use the Right Tools: A good circular saw with a fine-tooth blade works best to cut composite deck boards without chipping.
- Follow Manufacturer’s Instructions: Every brand may have specific installation requirements regarding spacing, fasteners, and expansion gaps.
- Secure Properly: Use the recommended clips or screws to prevent movement and squeaking over time.
- Leave Gaps: It helps with drainage and prevents board warping.
