What Is Composite Decking?

Composite decking is a modern alternative to traditional wood decking and is made from a blend of materials. It typically consists of a mix of recycled wood fibers and recycled plastic, although the exact composition can vary depending on the brand and product. This combination of materials offers several benefits over traditional wood decking. Here at Trade Warehouse, we supply the full range of composite decking boards to meet your needs.

Composite decking blends the natural beauty of wood with the durability and low maintenance of synthetic materials. This guide explores the advantages of composite decking, providing insights into why it's an increasingly preferred option for UK homeowners. We will explore the key benefits, helping you understand why it stands out as an excellent choice for your outdoor space.

Choosing Between Wood, Plastic, and Composite Decking in the UK

When deciding on the most suitable decking material in the UK, consider the specific advantages and disadvantages of timber, plastic, and composite materials.

Timber Wood Decking

  • Authentic Aesthetic: Offers a natural wood grain appearance, highly valued for traditional British garden designs.
  • Strength: Provides solid construction, crucial for the UK's varied outdoor uses.


  • Maintenance Costs: Requires more upkeep over its lifespan, which can add up in the UK's damp climate.
  • Susceptibility to Damage: Prone to rot and insect infestation over time, a notable concern in many UK regions.

Plastic Decking in the UK

  • Lower Upfront Cost: Less expensive initially, appealing to those with a tight budget.
  • Low Maintenance: Resistant to insects and requires minimal upkeep, a plus in the UK's busy lifestyle.


  • Weather Susceptibility: Can warp or bend in higher temperatures, a consideration during the UK's occasional hot spells.
  • Aesthetic Limitations: Lacks the natural look of timber, which might be a drawback for those seeking a traditional garden appearance.

What is the Composition of Composite Decking?

Composite decking, a blend of recycled hardwood fibers and high-grade recycled plastics (polyethylene), is revolutionizing garden decking in the UK. This eco-friendly composition, enhanced with quality additives, bonding agents, and tints, offers a durable and aesthetically pleasing alternative to traditional decking materials.

How is Composite Decking Manufactured?

The manufacturing process, known as co-extrusion, is a high-tech procedure that melds these materials at high temperatures. This process ensures uniformity and durability, making the decking suitable for the UK's diverse weather conditions. It involves shaping the molten blend through a die system to form the decking boards.

What is the Longevity of Composite Decks in the UK?

Composite decks are renowned for their long lifespan, typically lasting several decades. This durability is particularly beneficial in the UK, where the weather can be harsh and unpredictable. The robust nature of composite decking means it can withstand rain, wind, and occasional snow without deteriorating quickly.

What are the Primary Advantages of Composite Decking?

The main advantages include low maintenance requirements, a variety of style options, environmental friendliness, resistance to insects and pests, hidden fasteners for a sleek look, and water resistance, making it ideal for the UK's often wet conditions.

How Does Composite Decking Compare in Cost to Other Materials?

While the initial cost of composite decking might be higher than traditional wood or plastic decking, it offers significant long-term savings. The reduced maintenance and upkeep requirements make it a cost-effective choice over time, an important consideration for UK homeowners.

What Makes Composite Deck Boards Suitable for the UK?

Decking boards are specifically designed to cater to the UK's climate. Their FSC certification assures that the wood fibers used are sourced sustainably, aligning with the UK's increasing environmental consciousness. The boards are engineered to withstand the UK's varied weather, ensuring durability and maintaining their aesthetic appeal over time.

Are Composite Decks Eco-Friendly?

Yes, composite decks are an eco-friendly option. The use of recycled materials reduces the impact on forests and minimizes waste. This aspect is increasingly important for UK homeowners who are environmentally conscious and looking for sustainable building materials.

How Does Composite Decking Perform in Wet Conditions?

Composite decking performs exceptionally well in wet conditions, making it an ideal choice for the UK. Its slip-resistant surface provides safety during rainy periods, and its water-resistant properties prevent rotting and warping.

Is Special Maintenance Required for Composite Decks in the UK?

Composite decking requires minimal maintenance, which is a major advantage in the UK. It does not need to be sanded, varnished, or painted, and simple cleaning with soap and water is usually sufficient to keep it looking new.
