The natural product wood is always unique. Due to its hardness and resilience, a distinction is made between hardwood and softwood, with hardwood being very popular due to its wide range of uses.

In a nutshell

  • The kiln density is used to classify the wood as hardwood or softwood
  • Robinia wood valuable and robust
  • Teak is purely imported wood
  • The sweet chestnut has a very noble wood
  • Hardwoods mainly from deciduous trees

Hardwood at a glance

Mainly hardwoods come from deciduous trees. Softwood and hardwood are differentiated on the basis of the existing kiln density. This stands for the average raw density of completely dry wood. The wood moisture content is 0 percent. It is given in g/cm³. If this specification is over 0.55 g/cm³, then it is hardwood. Anything below that represents softwood.

frequently asked Questions

What are the differences between softwood and hardwood?

The kilned density is used to assess or classify wood into hardwood or softwood. The fiber density and the narrowness of the vascular structure of the wood indicate the hardness and resilience of each individual wood. A guide value of 0.55 g/cm³ was set. Wood with a kilned density above the guide value is considered hardwood. They are more resilient and harder. The wood underneath is called softwood.

How can wood be cared for in the garden?

Regular maintenance is required 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 purpose. Faded garden furniture can be given a new shine quickly, for example by using a teak degreyer. In addition, all new coats of paint should always be well prepared. Two coats of paint within two to three days are always advisable.

What to look out for when buying tropical woods?

If possible, the purchase of tropical wood should be avoided. Despite plantations, some of these are still illegally harvested. They can confidently be exchanged for local woods, including beech, robinia and oak. These have the same properties. However, if it absolutely has to be tropical wood, then you should definitely pay attention to the FSC seal. It stands for Forest Stewardship Council, an organization that promotes sustainable cultivation.
