Timber vs Composite Decking: The Basics

Before making a decision on your decking, it's essential to grasp the basics of both timber and composite options. Understanding the fundamental characteristics of each material will help you make an informed choice that suits your needs and preferences.

What is Timber Decking?

Timber decking is made from natural wood, offering a unique, rustic appearance that many homeowners desire. It is available in various types, including hardwood and softwood, each with its own set of characteristics and benefits. Timber decking is often prized for its natural beauty and the warmth it brings to outdoor spaces.

The types of timber used for decking vary, with some of the most popular being durable hardwoods that can withstand harsh weather conditions. The natural variation in timber gives each deck a unique character, which is part of its appeal.

What is Composite Decking?

Composite decking, on the other hand, is manufactured from a blend of wood fibres and plastics. This composition gives composite decking its durability and resistance to rot, mould, and insect damage. Composite materials are designed to mimic the appearance of natural timber while offering enhanced performance and lower maintenance requirements.

Composite decking is available from various leading brands, offering a range of colours and styles to suit different tastes and architectural styles. The use of composite materials in decking represents a modern approach to outdoor flooring, combining aesthetics with functionality.

Pros and Cons of Timber Decking

When considering decking materials, timber stands out for its natural beauty and specific benefits. Timber decking has been a long-standing choice for homeowners due to its unique characteristics and advantages.

Advantages of Natural Timber

Natural timber offers several benefits that make it a preferred choice for many. One of the primary advantages is its aesthetic appeal.

Aesthetic Appeal and Natural Beauty

Timber decking is praised for its natural beauty, which can enhance the overall look of an outdoor space. The variety of timber species available allows homeowners to choose a style that suits their preferences.

Durability and Weather Concerns

Timber decking can be susceptible to weather damage, including rot, mould, and insect infestation if not properly maintained.

Australian Climate Considerations

The Australian climate can be particularly harsh on timber decking, with high UV levels and varying moisture conditions. This requires careful selection of timber species and regular maintenance to ensure longevity.

Pros and Cons of Composite Decking

For homeowners weighing their decking options, composite decking stands out due to its long-lasting nature and minimal maintenance requirements. Composite decking, made from a combination of materials, offers a unique set of benefits and drawbacks that are essential to consider.

Advantages of Composite Materials

Composite decking is renowned for its numerous advantages, making it a popular choice among homeowners.

Low Maintenance Benefits

One of the primary benefits of composite decking is its low maintenance requirements. Unlike timber decking, composite materials do not need to be stained or sealed regularly, saving time and effort.

Resistant to rot, mould, and mildew
Easy to clean with simple soap and water

Longevity and Durability

Composite decking is also known for its durability and longevity. It can withstand harsh weather conditions and heavy foot traffic without significant wear and tear.

Consistent Appearance and Colour Options

Composite decking comes in a variety of colours and styles, offering a consistent appearance that does not fade quickly. This ensures that the decking maintains its aesthetic appeal over time.

Disadvantages of Composite Decking

While composite decking has several benefits, it also has some drawbacks that need to be considered.

Higher Initial Investment

One of the main disadvantages of composite decking is its higher upfront cost compared to timber decking. Although it may save money in the long run through reduced maintenance, the initial investment can be a barrier for some homeowners.

Heat Retention in Australian Summers

Composite decking can retain heat, making it uncomfortable to walk on during Australian summers. This is a crucial consideration for homeowners who plan to use their decking extensively.

Limited Repair Options

Unlike timber decking, which can be repaired relatively easily, composite decking has limited repair options. Damaged boards often need to be replaced entirely, which can be costly and inconvenient.

Cost and Installation Comparison

When deciding between timber and composite decking, one crucial factor to consider is the cost and installation process.

The initial cost of materials and installation is a significant consideration for homeowners. Timber decking is generally less expensive upfront, with costs varying depending on the species and quality of the timber.

Popular Australian Timber Species and Their Costs

Australia offers a variety of timber species suitable for decking, each with its own cost profile. Some popular choices include:

Spotted Gum: Known for its durability and attractive appearance, Spotted Gum is a popular choice, priced around $100-$150 per square meter.
Blackbutt: A durable and versatile timber, Blackbutt is moderately priced, costing between $80-$120 per square meter.
Merbau: A hardwood with high durability, Merbau is priced higher, ranging from $150-$200 per square meter.

Installation Considerations for Both Materials

The installation process for both timber and composite decking requires careful planning. Factors such as the complexity of the design, the size of the deck, and the installer's labour costs can significantly affect the overall cost. Generally, composite decking is more straightforward to install, potentially reducing labour costs.

Long-term Value Assessment

While timber decking may be cheaper initially, composite decking offers long-term value through its durability and low maintenance requirements. Composite decking resists rot, mould, and insect damage, potentially saving homeowners on repair and replacement costs over time.

Conclusion

Ultimately, the choice between timber and composite decking depends on individual preferences, budget, and specific needs. When deciding on the ideal decking material for your outdoor space, it's essential to weigh the pros and cons of each option.

Timber decking offers a natural aesthetic, while composite decking provides durability and low maintenance. By considering factors like durability, maintenance, cost, and environmental impact, you can make an informed decking decision that suits your lifestyle.
