The natural product wood is always unique. Due to its hardness and resistance, a distinction is made between hardwood and softwood, with hardwood being very popular due to its diverse uses.
In a nutshell
- By means of kiln density, there is a division into hard or soft wood
- Robinia wood is valuable and robust
- Teak is a pure import wood
- The sweet chestnut has a very noble wood
- Hardwoods mainly from deciduous trees
Overview of hardwood
Hardwoods mainly come from deciduous trees. The distinction between softwood and hardwood is made on the basis of the existing kiln density. This stands for the average density of completely dry wood. The wood moisture is 0 percent. It is given in g / cm³. If this figure is above 0.55 g / cm³, then it is hardwood. Everything underneath stands for softwood.

frequently asked Questions
For assessment or The classification of wood into hard or soft wood is based on the kiln density. The fiber density and the narrowness of the vascular structure of the wood refer to the hardness and resilience of each individual wood. A guideline value of 0.55 g / cm³ was set. Woods with a kiln density above the standard value are considered hardwood. They are more resilient and tougher. Woods lying underneath are referred to as softwood.
Regular maintenance is necessary here. However, only agents that do not contain any solvents or biocides should be used. The trade offers wood oils and special care products for this. In this way, faded garden furniture can quickly be given a new shine, for example by using a teak gray remover. In addition, all new coatings should always be well prepared. Two coats within two to three days are always advisable.
If possible, you should refrain from buying tropical woods. In spite of the plantations, some of these are still being beaten illegally. They can confidently be exchanged for native woods, including beech, robinia and oak. These have the same properties. However, if it has to be tropical woods, then you should definitely pay attention to the FSC seal. It stands for Forest Stewardship Council, an organization that advocates sustainable cultivation.
