Biological durability

The biological durability of wood is its resistance to weathering and to attack by living organisms such as fungi and insects. This is substantially determined by the chemical composition and structure of the wood and its ability to absorb water.

Based on a number of tests (according to European norm NBN EN 350-1) wood was divided into a number of sustainability classes.

Resistance against fungi

Class Durability Significance under Belgian climatic conditions
1 Very durable 25 years and more
2 Durable 15-25 years
3 Moderately durable 10-15 years
4 Little durable 5-10 years
5 Non durable Less than 5 years
