What Is Composite Decking?

Composite decking is made from a blend of wood fibers and plastic, creating a material that combines the look of wood with the durability of synthetic materials. It is often marketed as a low-maintenance, long-lasting alternative to traditional timber decking.

Most composite boards are made using a process known as co-extrusion, which wraps the core of the board in a layer of durable, weather-resistant plastic to protect it from moisture, fading, and stains.

Advantages of Composite Decking:

Low Maintenance: Unlike timber, composite decking does not require regular staining, sealing, or painting. It only needs an occasional cleaning with soap and water to maintain its appearance.
Durability: Composite decking is resistant to weathering, rotting, and insect damage. It does not splinter, warp, or fade over time, making it a great choice for areas with extreme weather conditions.
Environmentally Friendly: Many composite decking products are made from recycled materials, including plastic and wood fibers, which reduces waste and helps conserve natural resources.
Variety of Styles: Composite decking comes in a wide range of colors, textures, and finishes, making it easy to find a design that matches your aesthetic preferences.
Long Lifespan: Typically, composite decks have a longer lifespan than timber decks, often lasting up to 25-30 years with minimal wear.

Disadvantages of Composite Decking:

Initial Cost: Composite decking is usually more expensive than timber decking upfront, which can be a significant consideration if you’re working with a tight budget.
Heat Retention: Composite decking can absorb more heat than timber, which can make the surface uncomfortable to walk on during hot summer months, especially in areas with direct sunlight.
Limited Repair Options: While composite decking is durable, it can be more challenging to repair than timber. If a board is damaged, it typically needs to be replaced rather than repaired.

What Is Timber Decking?

Timber decking is the traditional choice for outdoor decks, made from natural wood such as cedar, pine, redwood, or tropical hardwoods. Timber provides a warm, natural aesthetic that many homeowners prefer. It’s a versatile material that can be stained or treated to achieve different looks, and it can be customized to fit a variety of deck designs.

Advantages of Timber Decking:

Natural Look: Timber offers a classic, authentic wood appearance that many homeowners find appealing. The texture and grain of wood give a deck a timeless, natural beauty that is hard to replicate with synthetic materials.
Customizable: Timber can be stained or painted in virtually any color, allowing you to change the appearance of your deck over time. Additionally, it’s easy to make repairs to individual boards if needed.
Lower Initial Cost: Timber decking tends to be more affordable than composite decking upfront, making it a popular choice for homeowners on a budget.
Environmental Impact: If you choose sustainably sourced timber, it can be an environmentally friendly option. Wood is a renewable resource, and many timber decking products are certified by organizations like the Forest Stewardship Council (FSC).

Disadvantages of Timber Decking:

High Maintenance: Timber decking requires regular maintenance to keep it in good condition. You’ll need to stain, seal, and paint it periodically to protect it from moisture, UV rays, and the elements. Neglecting these tasks can lead to issues like rotting, warping, or fading.
Susceptible to Damage: Timber is more vulnerable to damage from pests, such as termites and woodboring insects, as well as wear from foot traffic and weathering. Over time, timber decks can splinter and crack.
Shorter Lifespan: Compared to composite decking, timber decks typically last 10-15 years before they need major repairs or replacement. However, with proper care, some types of timber decking can last longer.

Key Differences Between Composite and Timber Decking

1. Durability

Composite Decking: Resistant to weathering, rotting, and insect damage. It does not warp or splinter and can last up to 25-30 years with minimal maintenance.
Timber Decking: Timber is more susceptible to the elements, especially moisture and UV rays, leading to potential issues like rotting, warping, and fading. It typically lasts 10-15 years, depending on the type of wood and maintenance.

2. Maintenance

Composite Decking: Requires very little maintenance, with only occasional cleaning needed to preserve its appearance.
Timber Decking: Requires regular upkeep, including staining, sealing, and painting to protect it from weathering and to extend its lifespan.

3. Cost

Composite Decking: More expensive upfront but can save money over time due to reduced maintenance and longer lifespan.
Timber Decking: Less expensive initially, but the cost of maintenance and repairs can add up over time.

4. Aesthetics

Composite Decking: Available in a wide variety of colors and textures to mimic the look of wood, though it may lack the natural character of real timber.
Timber Decking: Offers a natural, classic look with authentic wood grain patterns that many homeowners find appealing. It can be customized with stains and finishes.

5. Environmental Impact

Composite Decking: Made from recycled materials, reducing waste and helping conserve natural resources. However, the production process can be energy-intensive.
Timber Decking: If sourced sustainably, timber is a renewable resource. However, deforestation and poor forest management practices can have negative environmental consequences.

Frequently Asked Questions About Decking

What is the difference between composite decking and timber decking?

Composite decking is made from a mix of recycled materials like plastic and wood fibers, offering low maintenance and durability. Timber decking, on the other hand, is constructed from natural wood species like cedar, ipe hardwood, or pressure-treated pine, showcasing the natural beauty and grain patterns of real wood. Each has its own benefits depending on your preferences for maintenance, cost, and environmental impact.

Is composite decking more expensive than wood decking?

Yes, composite decking typically has a higher initial cost compared to traditional timber decking or pressure-treated lumber. However, it offers lower maintenance costs over time, as it doesn’t require annual maintenance like staining or sealing that real wood needs to stay in good condition.

Does composite decking require a lot of upkeep?

Not at all! Composite decking offers very little maintenance compared to traditional wood. It doesn’t require staining, sanding, or sealing, and it’s resistant to insect damage, rot, and splintering. Simply keep it clean by washing it occasionally, and it will last for years.

How does natural wood compare to composite boards in terms of environmental impact?

Natural wood, when responsibly sourced, can be a sustainable choice, but it requires regular treatment to ensure durability and prevent wear. Composite decking uses recycled materials and has a lower carbon footprint during its manufacturing process. Both materials have pros and cons in terms of environmental impact, so your choice depends on your priorities.

Can composite decking boards absorb moisture?

Composite boards are designed to be water-resistant, meaning they do not absorb moisture like untreated wood. Capped composite decking, in particular, has an added plastic film layer that enhances its resistance to water, ensuring it doesn’t warp or rot over time.

What are the benefits of composite decking vs wooden decks?

Composite decking offers durability, resistance to wear, and a variety of color tints and grain designs for a more modern composite decking look. Wooden decks, such as those made from hardwood decking or pressure-treated pine, are prized for their natural feel and aesthetic but require regular maintenance to retain their appearance and structural integrity.

Which decking material is better for homeowners on a budget?

Pressure-treated pine is an affordable and traditional timber option that appeals to many homeowners due to its lower initial cost. While composite decking boards may be more expensive upfront, their low maintenance requirements can save money in the long run.

Can composite boards be used for a deck project in any climate?

Yes, composite decking is designed to withstand harsh weather conditions, making it suitable for any climate. Its durable materials ensure it resists fading and cracking due to UV exposure or extreme temperatures, making it an excellent choice for those seeking a long-lasting decking solution.
