Composite Decking

What Is Composite Decking Made Of?

Composite decking is manufactured from WPC (Wood-Plastic Composite), a material that combines recycled hardwood fibres with recycled polyethylene. This engineered composition harnesses the best properties of both wood and plastic to create decking boards that outperform traditional timber in several key areas.

The wood fibre content provides structural strength and a natural appearance, while the plastic polymer component delivers moisture resistance and dimensional stability. Unlike solid timber, WPC does not absorb water, which eliminates the rot, warping, and splitting that commonly affects wooden decking over time.

The non-porous surface of composite decking boards prevents moisture penetration, meaning the boards are not susceptible to mould, mildew, or damage from wood-eating insects. This composition ensures that the decking maintains its structural integrity and appearance throughout its lifespan.

Why Choose Composite Decking Over Wood?

The choice between composite and timber decking comes down to long-term performance, maintenance requirements, and overall lifespan. Understanding how these materials compare helps you make an informed decision for your outdoor space.

Maintenance Requirements

Timber decking requires regular maintenance to remain in good condition. This includes annual treatment with wood preservative, sanding to remove splinters, and repainting or staining every few years. Composite decking boards require none of this ongoing work. A periodic wash with soapy water is typically all that is needed to keep the boards clean.

Lifespan and Durability

Standard timber decking typically lasts 10-15 years before requiring replacement, with significant maintenance throughout that period. Composite decking is engineered to last considerably longer, backed by our 20 year warranty. The material does not rot, warp, or suffer from the moisture-related deterioration that shortens the life of wooden decking.

Safety

Timber decking develops splinters as it ages, particularly as the surface weathers and dries out. This presents a hazard for bare feet, children, and pets. Composite decking is splinter-free throughout its lifespan and features an anti-slip surface that maintains grip even when wet, making it safer around pools and in areas exposed to rain.

Weather Resistance

Timber absorbs moisture, leading to swelling, warping, and eventual rot. In the UK climate, where rain is frequent, wooden decking is constantly exposed to conditions that accelerate deterioration. Composite decking is non-porous and does not absorb water, making it inherently better suited to British weather conditions. The UV-resistant composition also prevents the significant fading that affects untreated timber.

Types of Composite Decking Boards

Composite decking boards are available in different constructions to suit various requirements and preferences. Whether you are searching for cheap composite decking options or exploring our full range, understanding the differences between board types helps you select the right product for your project.

Hollow Composite Decking Boards

Hollow composite decking boards have an internal chamber structure that reduces weight while maintaining strength. This construction makes the boards lighter and easier to handle during installation. Hollow boards are suitable for most residential decking applications where pedestrian traffic is the primary load. The reduced weight also means less stress on the supporting subframe.

Solid Composite Decking Boards

Solid composite decking boards are denser and heavier than hollow alternatives. This construction provides a more substantial feel underfoot and can handle heavier loads. Solid boards are often preferred for commercial applications, areas with heavy furniture, or where a more robust feel is desired. The denser construction also provides enhanced sound dampening.

Dual-Sided Boards

Our composite decking boards feature a dual-sided design. One side has a 3D deep embossed woodgrain finish that replicates natural timber, while the reverse side features straight grooves for a sleeker, more contemporary appearance. This gives you the flexibility to choose the look that best suits your garden design during installation.

Installation and System

Composite decking is designed for straightforward installation, whether you are working with a professional installer or undertaking a DIY project.

Subframe Requirements

Composite decking boards are installed onto a supporting subframe, typically constructed from treated timber joists or composite joists. The subframe provides the structural foundation for the deck and must be level and properly spaced according to the board specifications. Correct subframe construction is essential for the longevity and performance of the finished deck.

Clip System Installation

Our composite decking uses a hidden clip system that secures the boards to the subframe without visible fixings on the deck surface. The clips slot into grooves on the edge of each board, creating a clean, seamless appearance. This system speeds up installation and ensures consistent spacing between boards for drainage and expansion.

DIY and Trade Installation

The installation system is accessible for competent DIY installers while also being efficient for trade professionals. Comprehensive installation guides are provided with all orders. The lightweight nature of composite boards (particularly hollow boards) makes handling easier than heavy timber. For those seeking composite decking near me with installation support, we can provide guidance on finding qualified installers in your area.

Colours, Finishes and Design Options

Composite decking is available in a range of colours and finishes to suit different property styles and personal preferences.

Grey Composite Decking

Grey composite decking is one of the most popular choices for contemporary gardens. The neutral tone complements modern architecture and works well with a range of outdoor furniture styles. Grey provides a sophisticated, understated appearance that does not compete with garden planting or architectural features.

Charcoal

Charcoal offers a darker alternative to grey, creating a bold, contemporary statement. This colour works particularly well in modern garden designs and provides striking contrast against green foliage and colourful planting. Charcoal decking suits minimalist outdoor spaces and contemporary architecture.

Teak

Teak provides warm, natural wood tones for those who prefer a traditional timber appearance. This colour suits period properties, cottage-style gardens, and outdoor spaces where a natural, organic look is desired. Teak composite decking delivers the appearance of exotic hardwood without the associated maintenance requirements.

Design Flexibility

The range of colours, combined with the dual-sided board design, provides flexibility to create a deck that complements your property. The 3D embossed woodgrain side offers authentic timber character, while the grooved reverse suits contemporary, minimalist aesthetics. Boards can be laid in different patterns to create visual interest.

Where Composite Decking Is Used

Composite decking suits a wide range of outdoor applications in both residential and commercial settings.

Garden Decking

Residential garden decking is the most common application for composite boards. The material creates attractive outdoor entertaining areas, seating zones, and transitions between house and garden. Composite decking UK homeowners install provides a durable surface for furniture, barbecues, and daily use throughout the year.

Patios and Outdoor Living Areas

Composite decking provides an alternative to paved patios, offering a warmer feel underfoot and a different aesthetic. Decked areas work well for outdoor dining spaces, lounging areas, and extensions of indoor living spaces. The splinter-free, anti-slip surface is practical for areas used barefoot.

Raised Decking Areas

Raised decks make use of sloped gardens, create level outdoor spaces, or provide elevated entertaining areas. Composite decking is well-suited to raised structures where exposure to weather is increased. The moisture resistance and dimensional stability of composite boards perform well in these more demanding applications.

Commercial Outdoor Spaces

Commercial properties including restaurants, hotels, bars, and offices benefit from composite decking's professional appearance and minimal maintenance requirements. The material handles heavy footfall and maintains its appearance in demanding environments.

Maintenance and Longevity

One of the primary advantages of composite decking is the minimal maintenance required to keep it in good condition.

No Painting or Staining

Composite decking never needs painting, staining, or treating with preservatives. The colour is integral to the material rather than a surface coating, so there is no paint to peel or stain to fade unevenly. This eliminates the regular maintenance cycle that timber decking requires.

Easy Cleaning

The non-porous surface resists staining and can be cleaned with soapy water and a stiff brush. Bird droppings, general dirt, and most marks wash away without specialist cleaning products. The board composition also resists mould and mildew growth, reducing cleaning frequency in shaded or damp areas.

Long Lifespan

Composite decking is engineered for long-term performance in outdoor conditions. The material does not rot, warp, or split. It resists moisture damage and UV degradation. Our composite decking comes with a 20 year warranty, providing confidence in the product's longevity and performance.

Safety and Performance

Composite decking is designed with safety in mind, particularly for family gardens and areas used barefoot.

Anti-Slip Surface

The textured surface of composite decking boards provides grip underfoot, even when wet. This makes composite decking suitable for pool surrounds, garden steps, and areas exposed to rain. The anti-slip properties are maintained throughout the product's lifespan.

Splinter-Free

Unlike timber decking, which develops splinters as it ages and weathers, composite decking maintains a smooth, safe surface throughout its life. This makes it particularly suitable for areas where children play and for use barefoot during warmer months.

Safe for Children and Pets

The combination of anti-slip surface and splinter-free construction makes composite decking a practical choice for family gardens. The smooth surface is comfortable for pets' paws, and there are no splinters or rough edges to cause injury. The material does not absorb pet odours and is easy to clean.
