Durability of Wood

Holz als CO2-neutraler Baustoff - Forschung und Studien

Traditionally, wood has not left any environmentally damaging footprints.


Wood has been serving humans as a construction material since antiquity. The first pylon constructions were documented from the time of 2500 BC (before Christ). Some residential buildings from the middle ages, primarily built as log houses and in no way comparable to comfortable modern wood buildings, are still in existence today.


Wood is not only a very old but also an extraordinarily durable material. Wood's natural physical properties, such as the ability to absorb and regulate moisture, protect it while the tree is growing. Even after the wood has been processed, these properties are maintained and are a significant basis for particularly long-lasting and stable structures. The manufacturing and processing methods of wood have been continuously improved upon.


Technical wood drying and wood finishing processes have since given rise to a wide range of styles and designs that meet the highest requirements for stability, durability and comfort.


The positive experiences with wooden structures in recent decades have, in the meantime, also been introduced into the standards, for example in DIN 68800 or ÖNORM B 3802. With the exception of where they come into contact with the ground or salt water, it is possible to develop wooden structures of far above-average service life and lasting value without having to use any chemicals.
