But then with all these appellations and countries of different origins, what type to choose for its terrace? In addition, wood drying is a key factor in the use of this wood outdoors. Nature Bois Concept enlightens you on the question on several points.

What are the characteristics of Cumaru exotic wood?

Wood of South America, naturally rot-proof of class 4, it is known and recognized to be an alternative to Ipe. Cheaper than the latter, it is very similar with a density of about 1000 kg/m3 and a great resistance to external aggressions such as insects or fungi.

Wood can be totally immersed in fresh water, it is common to use in wet areas like a pool ride. Naturally nervous, it must be marketed dry kiln (KD) in order to achieve a stability allowing the laying on terrace or wood landscaping (hygrometry rate between 16% and 18%). This nervousness gives it some peculiarities that make the originality of this essence. The wood has an atypical veining that gives it a beautiful finish.

Is the color of exotic Cumaru wood a guarantee of quality?

We cannot say that the color of the wood is an indicator of the quality of the exotic Cumaru wood.

There are many varieties of Cumaru with shades of colors, this is valid for many exotic species such as IPE which has about 30 different shades. So we should not focus on the color of the wood, but rather on the quality of the production.

Brazil, Bolivia, Colombia or Peru, does the origin of the wood induce its quality?

Yes, it is possible that according to the countries of origin, and the plots of growth, the wood is of better quality. Now the name Cumaru respects an initial quality that is very satisfactory. It would, therefore, be inaccurate to judge the quality only on the origin, because there are other factors which intervene in the quality of the product.

The origin of wood

According to the country of origin, according to the climate and the plot, the wood will have divergent qualities. This is a factor in the quality of the product but it is not the only one.

Drying

Do not forget to check the drying of the wood, key point of a good Cumaru terrace blade. The wood must be kiln dried (KD for Kiln Dry). This point is imperative, the exotic wood Cumaru being naturally nervous, it must be dried in a dryer at a hygrometry rate between 16% and 18% (according to DTU 51.4 decking wood). With proper drying, it achieves stability and durability similar to IPE for a durable deck.

Sustainable development of its production

The second factor is wood certification. By turning to a supplier with a quality supply chain and legal, you fight against the slaughter and distribution of illegal timber. These woods are not subject to quality checks and therefore they will be consistently lower quality.
