4m Signature Composite Decking Board
Cladco 4m Signature wood-effect composite decking boards are designed to replicate the appearance of natural timber and are available in eight attractive shades. Each board features a dual-sided, reversible profile - with narrow grooves on one side and an authentic woodgrain-effect pattern on the other.
Made from recycled materials, these eco-friendly boards offer a sustainable alternative to traditional timber decking. Resistant to rot and splintering, composite decking requires no staining or painting, offering a low-maintenance solution that doesn’t compromise on style or durability.

About Our Wood Effect 4m Composite Decking Boards
If you are looking to transform your outdoor space with a realistic wood-effect decking area, our reversible 4m woodgrain effect composite decking boards are the perfect choice. Featuring narrow grooves on one side and a detailed woodgrain effect on the other, these durable, low-maintenance boards elevate your garden or outdoor spaces with with both style and practicality.
Cladco composite decking offers multiple benefits over timber decking, including resistance to rotting, splintering, warping, and insect damage. Unlike timber, our Signature boards require no staining, varnishing, or painting. To maintain their appearance, we recommend regular cleaning using Cladco composite decking cleaner to remove dirt and debris. For boards that have faded over time, a composite decking reviver can help restore their original colour.
For enhanced protection against UV rays, stains, mould, and colour fading, consider our premium ProDeck range of composite decking.
To qualify for the extended 15-year warranty, we advise installing Signature composite decking boards onto a Cladco recycled plastic decking subframe, and following our installation guide.

Supporting Trims and Fixings
To support a clean and efficient installation, the Signature range includes a selection of matching trims and accessories, including:
For consistent board spacing and easier installation - especially at butt joints - we recommend using T-clips. These contribute to a professional finish while allowing rainwater to drain effectively, helping prevent surface pooling. For a more streamlined appearance with narrower gaps between boards hidden clips are also available.
Colour Variation & Installation Advice
Due to the high timber content of composite decking, natural colour variation and weathering are to be expected. In the first few months after installation, your boards will go through an initial colour stabilisation process, which may be affected by sun exposure and local weather conditions.
To minimise shade variation:
- Order all required boards in one batch.
- Inspect and mix boards before installation for a more consistent, blended finish.
- Be aware that boards may appear different in wet and dry conditions, which can make tonal differences more noticeable.
