Common Types Of Timber For Decking
There are several timber species available for decking, each with its own unique properties. Below, we will explore the top choices based on performance, appearance, and sustainability.
Accoya Wood: The Superior Choice
Accoya wood is one of the top contenders when it comes to decking material. This timber is often praised for its durability, sustainability, and low maintenance.
Features Of Accoya Timber
- Durability: Accoya wood is highly durable, with exceptional resistance to moisture, decay, and insects. It is ideal for Australian climates, particularly in coastal regions.
- Sustainability: Accoya is made from sustainably sourced wood, and its production process is environmentally friendly. The wood is modified using a non-toxic process called acetylation, which enhances its natural properties.
- Low Maintenance: Accoya requires minimal maintenance compared to other timbers. It doesn’t need to be re-oiled as often, which makes it a low-maintenance choice for homeowners.
Why Choose Accoya For Decking?
- Long-lasting and resistant to decay.
- Environmentally friendly and sustainable.
- Low maintenance and high performance.
Hardwood Decking: A Popular Choice For Strength And Style
Hardwood timber is another popular option for decking in Australia. Species such as merbau, ironbark, and spotted gum are frequently used for decking due to their strength and natural beauty.
Features Of Hardwood Decking
- Strength: Hardwood species like merbau and spotted gum are known for their robustness and are able to handle heavy foot traffic and wear.
- Appearance: Hardwood timbers offer a rich, natural aesthetic with varying colours and grain patterns.
- Longevity: These timbers are highly durable and can last for many years with proper maintenance.
Pros Of Hardwood Decking
- Strong and long-lasting.
- Attractive appearance that improves with age.
- Ideal for heavy-duty outdoor use.
Softwood Decking: Affordable And Versatile
Softwood timbers, such as pine, are often used for decking due to their affordability and ease of use. While they may not be as durable as hardwood or modified wood like Accoya, they still provide a solid decking solution for those on a budget.
Features Of Softwood Decking
- Cost-Effective: Softwood decking is generally less expensive than hardwood or modified timber options.
- Easy to Work With: Softwood is easier to cut and shape, making it ideal for DIY projects.
- Maintenance: While not as durable as hardwood, softwood can be treated with preservatives to improve its resistance to moisture and decay.
Pros Of Softwood Decking
- Lower cost compared to hardwoods and modified woods.
- Suitable for DIY installations.
- Can be treated for enhanced durability.
Composite Decking: An Alternative To Timber
Composite decking is made from a mixture of wood fibres and plastic, providing a low-maintenance alternative to traditional timber decking. While composite decking isn’t made from pure timber, it offers several benefits that may appeal to homeowners.
Features Of Composite Decking
- Low Maintenance: Unlike traditional timber, composite decking doesn’t require staining, sealing, or frequent cleaning.
- Durability: Composite decking is resistant to rot, insects, and fading, making it a great choice for high-moisture areas like poolsides.
- Environmental Impact: Many composite decking materials are made from recycled plastic and wood fibres, which reduces the environmental footprint.
Pros Of Composite Decking
- Requires minimal maintenance and upkeep.
- Highly resistant to weathering and fading.
- Often made from recycled materials.
Bamboo Decking: A Sustainable Option
Bamboo decking has gained popularity in recent years as a sustainable and eco-friendly alternative to traditional timber. It is highly renewable and offers a unique aesthetic.
Features Of Bamboo Decking
- Sustainability: Bamboo is one of the most sustainable materials available, as it grows much faster than traditional hardwoods.
- Durability: While bamboo is naturally durable, it is important to choose properly treated bamboo that has been carbonised to prevent moisture damage.
- Aesthetic Appeal: Bamboo has a distinctive look, with its natural texture and colour adding an exotic touch to your deck.
Pros Of Bamboo Decking
- Environmentally friendly and sustainable.
- Attractive appearance with a unique texture.
- Resistant to pests and decay when properly treated.
Factors To Consider When Choosing Timber For Decking
Now that we’ve explored some of the top timber options for decking, it’s essential to consider additional factors that can impact your decision.
Climate And Environmental Conditions
The climate in your region will significantly affect the performance of your chosen timber. For example, coastal areas with high humidity and salt exposure may require more durable timbers like Accoya or hardwoods, which can withstand these harsh conditions.
Timber Maintenance Requirements
Some timbers require more maintenance than others to preserve their appearance and strength. Softwoods, for instance, may need regular treatment to protect them from decay and moisture. Hardwoods and modified timbers like Accoya generally require less upkeep.
Aesthetic Preferences
Your personal taste plays a significant role in choosing the right timber for your deck. Hardwood timbers offer a natural and timeless aesthetic, while modified woods like Accoya offer a more modern and sleek finish. If you prefer a more unique look, bamboo decking may be the right choice for you.
Budget
Cost is often a determining factor in the choice of timber. Softwood decking is the most affordable option, while Accoya and hardwood decking are higher-end choices. Composite decking may also be more expensive initially but can save money in the long run due to its low maintenance requirements.
Conclusion
Selecting the best timber for your decking project requires careful consideration of several factors, including durability, aesthetics, maintenance, and sustainability. Accoya wood stands out as one of the best choices for long-lasting, low-maintenance decking that also has a minimal environmental impact.
However, for those on a budget or seeking a traditional appearance, hardwoods and softwoods are also excellent options. Composite and bamboo decking offer sustainable alternatives with distinct benefits, depending on your preferences and requirements.
By understanding the different types of timber available and evaluating your personal needs, you can make an informed decision that will result in a beautiful and durable deck for years to come.
Conclusion
What Is The Most Durable Timber For Decking In Australia?
Accoya timber is one of the most durable options for decking in Australia. Its acetylation process makes it highly resistant to moisture, decay, and insects, making it ideal for harsh outdoor conditions. Other durable hardwood options, like merbau and spotted gum, are also excellent choices for long-lasting decks, especially in coastal or high-humidity areas.
How Often Should I Maintain My Timber Deck?
The frequency of maintenance for your timber deck depends on the type of timber used. Hardwoods like merbau typically require less maintenance and can be cleaned once or twice a year. Softwood decks may need more frequent maintenance, including oiling or staining every 12-18 months, while Accoya timber has a low-maintenance requirement and only needs occasional cleaning to retain its appearance.
Is Composite Decking Better Than Timber?
Composite decking offers several advantages over timber, such as low maintenance and resistance to weathering, fading, and insects. It does not require staining or sealing, making it a convenient choice for busy homeowners. However, timber decking offers a more natural aesthetic and can be a better choice if you’re looking for authentic wood grain patterns and a traditional look for your outdoor space.
