Cumaru Rhombus 28x143mm

Important properties of Cumaru rhombus

  • The rhombus profile has the shape of a parallelogram (about 15 degrees). This diamond-shaped profile is suitable for open facade cladding. The longitudinal sides are slightly rounded to prevent splintering at the sharp corners.
  • Working width: 143 mm
  • The boards are sorted on one visible side, the rear may contain some scraping errors, tire marks and/or roller marks.
  • The production reserves the right to deviate a maximum of 3-4% from the head size, in order to be able to plan a nice, straight and dimensionally stable product. In addition, humidity can affect the head size (dry and warm weather causes shrinkage).
  • We supply wood at trade length. This means: not sawn square and not shortened to length, often with some excess length.
  • Dry cracks can be seen on the short sides. Always calculate at least 10 cm extra sawing loss in length.
  • Correct installation is very important. Good ventilation, sufficient framing and correct fastening are required. Before you start, read our mounting tips and instructions carefully!


This product is FSC 100% certified. The origin of FSC wood meets global standards for sustainable forest management. The forest will remain. Trees only disappear if they can be missed.

KD 18-20% Humidity

This product is machine dried back (kiln dried) to a moisture content that is in balance with the typical outdoor usage. Upon delivery, the product has a more or less elaborated shape and will mainly shrink or expand (provided assembling instructions are properly applied) depending on the weather conditions.

FAS Grade

This product is sorted according to the FAS (First and Second) grade. This is the most common and also the highest grade of (tropical) hardwood. With this grading, at least 83.3% of the wood is free from defects, small defects can occur over the remaining part. For complete defect-free processing, this product must be assembled saw-falling.


Cumaru is one of the hardest woods from the Amazon region. The durability is very high thanks to the good resistance to wood-destroying fungi and insects. Cumaru has a beautiful flame pattern and a beautiful color.

Cumaru is a reliable building material when it comes to structures that are subject to heavy loads. As a construction timber, it is ideal for outdoor applications such as bridges and locks and outdoor furniture in public areas. In addition, the wood is often used for wooden decking and terraces. Cumaru is also very suitable for heavily loaded floors in industry or in workshops.

This type of wood has a high density and a somewhat coarser structure that is often homogeneous. The fiber course is usually tightly alternating and often irregular. The grain is generally straight, but the wood has a rather pronounced crosshair. The grain is moderately coarse. Over the years, Cumaru discolours to a beautiful gray shade.


  • Versatile type of wood
  • Reliable material
  • Durability class 1
  • Quiet and simple texture
  • Good wear resistance and moderate deformation


Cumaru can be processed like a typical hardwood species. Screw connections must be pre-drilled to avoid cracks and damage. In addition, we always advise to use stainless steel screws and fasteners, this prevents stains on the wood. Make sure you have sharp tools due to the high hardness and the irregular wire.

Caution: Deep milling, longitudinal sawing or re-cutting can expose stresses. These stresses may have arisen during drying and processing. This is one of the reasons why we recommend adding 10% wood to your order. This way you can be sure that you have enough material to work with.

What is a rhombus board?

A Cumaru rhombus is a popular choice. It is a material that is popular to use untreated. The longitudinal sides of the plank are obliquely rounded, so that the water always drains outwards. The profile is extremely suitable for open facade cladding. Rhombus parts are ideal for facade cladding for houses or outdoor areas.
