Decking quality

To find decking boards of the best quality, it is important to choose a suitable type of wood, careful production and subsequent hand sorting. Betterwood Each board is additionally tested and advice during terrace construction ensures that the high material quality is maintained over the long term.

The best decking wood meets objective criteria such as high wood quality (Premium or FAS), long durability (resistance class 1-2), kiln drying (KD), and sustainable origin with FSC® certification. Your personal taste in color and grain also plays a role, which is why samples and advice are helpful in your selection.

The wood species differ primarily in durability, dimensional stability, price, and appearance. Tropical woods such as cumaru, ipe, or teak offer a very long service life and high stability, while European woods such as larch or Douglas fir are cheaper but less durable. In addition, color and grain vary greatly, so personal taste plays a role alongside technical properties.

The decking boards are sorted by hand according to strict criteria. Each board is inspected on both sides: the A-side must be free of defects such as deep cracks, planing defects, or large holes, while minor defects on the B-side are tolerated. If a board fails to meet the quality requirements, it is rejected.

Cracks and warping can be avoided primarily through proper drying and the right choice of wood. Kiln-dried wood with approximately 15% residual moisture content is significantly more dimensionally stable, and wood species such as teak are considered particularly durable. Additionally, treatment with decking oil and edge wax protects against cracks and ensures a long-lasting deck.

The durability of a wooden deck depends heavily on the wood species: Tropical woods such as Cumaru or teak can last over 1 years in resistance class 25, while European woods such as Douglas fir are often susceptible to fungal decay after just 5–10 years. Factors such as good ventilation, a slope, dry storage, and regular maintenance with oil or impregnation further extend the lifespan.

A wooden substructure adapts better to the working decking boards, eliminates tension, and thus prevents screws from breaking. While aluminum is extremely durable and very straight, it carries a higher risk of screw breakage and has a poorer environmental impact. Therefore, wood is recommended as a substructure in most cases.

The best system for concealed screwing is fastening from below, as it provides a secure hold, improves the terrace's ventilation, and reduces the risk of splintering. BioMadera Clips or Sihga DielenFix are particularly recommended. These are made of stainless steel and are suitable for all wood types, although installation is somewhat more complex.

Branded decking products offer the advantage of transparent quality and traceability, and reliable standards are maintained. Manufacturers have a long-term interest in satisfied customers, which is why they focus on sustainable production and high credibility.
