for Seamless Designs

Why 4 m and 5 m Decking Boards Are Especially Practical

Long board lengths like 4 m or 5 m decking boards offer several advantages: they enable a smooth, joint-minimised installation, ideal for large terraces where visual harmony is essential. Fewer board cuts mean reduced material waste – especially for symmetrical layouts with fixed widths.

Another benefit: continuous lengths create a calmer, more uniform surface with fewer structural interruptions. Fewer fixings are required, which often simplifies the installation and results in a cleaner overall look. This is especially valuable in modern architectural designs with clean lines.
If you value efficiency, visual appeal and long-term durability, extra-long decking boards offer a compelling solution both technically and aesthetically.

Choosing the Right Type of Decking Board for Your Project

WPC and BPC Solid Boards – Low Maintenance and Dimensionally Stable

If you're after a low-maintenance option with a modern appearance, WPC or BPC solid decking boards are an excellent choice. These composite materials are made from wood fibres and plastics, offering high dimensional stability, weather resistance and a splinter-free surface. Ideal for those who enjoy barefoot walking or want to avoid regular upkeep. Their solid structure makes them especially suitable for longer lengths such as 4 m or 5 m decking boards. Whether smooth, grooved or with a woodgrain texture – these surfaces support both classic and contemporary design styles.

Bangkirai Hardwood Boards – Natural, Durable, Full of Character

Bangkirai is a dense tropical hardwood known for its natural durability. A terrace built with Bangkirai boards can offer exceptional longevity when installed properly and maintained regularly. Over time, the wood develops a silver-grey patina – which can be delayed with suitable oil treatments. Compared to larch, Bangkirai is more resistant and longer-lasting, though it comes at a higher price point. Costs typically range between €50 and €90 per square metre, depending on board type and finish.

Autentica Solid Boards – The Modern Alternative

Autentica solid decking boards combine high strength with a sleek, modern aesthetic. Made from a high-quality composite of bamboo fibres and polymer, they are especially durable, colourfast and easy to maintain. Thanks to their elegant surface and impressive stability, they are a well-considered choice for anyone looking to combine design, strength and sustainability – even in extra-long formats.

What to Consider When Installing Long Decking Boards

Extra-long decking boards require careful planning, especially regarding the substructure, material properties and intended use. A solid supporting frame is crucial, tailored to both the length and material of the boards – for example, using the correct joist spacing. For WPC and BPC decking boards, it's also essential to allow for expansion gaps, as these materials expand and contract with temperature changes.
Depending on the environment, surface texture also matters: grooved decking boards provide better slip resistance and are ideal around pools. Smooth planed boards offer a modern look and feel pleasant under bare feet.

For hardwoods like Bangkirai, regular maintenance is key. Only with proper oil treatment and professional installation can the wood remain dimensionally stable and weather-resistant over time. Lastly, make sure the colour and texture of your boards harmonise with the surrounding architecture and furniture – for a visually cohesive terrace design.
