NATURAL DURABILITY AND TREATABILITY
| Funghi (according to E.N. standards): |
class 1 - very durable |
| Dry wood borers: |
durable - sapwood demarcated (risk limited to sapwood) |
| Termites (according to E.N. standards): |
class D - durable |
| Treatability (according to E.N. standards): |
class 4 - not permeable |
| Use class ensured by natural durability: |
class 3 - not in ground contact, outside |
| Species covering the use class 5: |
No |
| Note: |
Although BETE is mentioned in the natural durability class 1 towards fungi (very durable) in the standard NF EN 350-2, it is important to know that it is sensible to white rot "Coriolus versicolor" attacks, hence, its classification in class 2 (durable). According to the European standard NF EN 335, performance length might be modified by the intensity of end-use exposition. |
