4m Signature Solid Composite Decking Board
Cladco's 4m Signature solid composite decking board is a durable, high-quality alternative to traditional timber decking and is available in a choice of eight stylish composite colours. Adding composite decking to your garden is an excellent way to transform your outdoor space - especially in areas with high foot traffic or substantial outdoor furniture.
To qualify for our extended 15-year warranty, we recommend installing Signature composite decking boards onto a recycled plastic subframe, and in accordance with our installation guide.

Why choose our 4m solid composite decking boards
Thanks to its reversible, dual-sided design - with an authentic woodgrain effect on one side and low-slip narrow grooves on the other - you have the flexibility to choose the finish that best complements your outdoor space.
A popular choice for commercial and high-traffic environments, these solid-core boards deliver outstanding strength, structural integrity, and load-bearing capacity. Their enhanced sound absorption also makes them ideal for cafés, restaurants, terraces, and other public spaces.

Cladco 4m solid composite decking boards are made from 60% recycled hardwood fibres and 40% high-grade recycled plastics, bonding agents, additives, and tints. Part of our Signature range, these boards offer outstanding performance and come with a 15-year warranty for added peace of mind.
As part of the Signature range, we offer a complete selection of trims and fixings, including skirting trims, corner trims, fascia boards, and bullnose boards, to help you achieve a professional, cohesive finish.Â
or efficient installation and consistent spacing, particularly at butt joints, we recommend using T-clips. These fixings make installation easier and help ensure effective drainage between boards, reducing the risk of standing water. For a sleeker appearance, hidden clips are also available, allowing for tighter, less visible board gaps.
When compared to traditional timber decking boards, all of our composite decking boards require minimal maintenance and are easy to clean when necessary with the use of our ultimate decking cleaner. No staining, painting or varnishing is required to keep your composite decking looking its best for years to come. For long-term appearance and care, we also suggest using composite wood reviver to maintain your decking’s appearance.
Natural variations in colour and weathering are to be expected with composite decking due to its timber content. After installation, the boards will undergo a colour stabilisation process, influenced by factors such as sunlight exposure and local weather conditions.

For the most consistent results, we recommend ordering all your composite decking boards in a single purchase, as colours may vary between production batches. Even within the same batch, slight shade differences can occur. To help achieve a more blended appearance, lay out all boards prior to installation, identify any tonal variations, and mix them accordingly. Please also note that boards may appear different in wet and dry conditions.
