3. Conclusion

Today, wood durability is no longer synonymous with systematic chemical preservation. Today's architects and builders prefer a well-thought-out design which, by minimizing the risk of wood becoming damp, will prevent the appearance of fungi. The key to constructive prevention often lies in the mix of materials when wood, combined with metal, concrete or glass, is used to optimum effect.

The durability of structures also depends on the choice of wood that is sufficiently durable for the intended use, the biological risks involved and the expected service life.

To make the most of local forest resources, untreated (and therefore sapwood-free) wood is most often larch, Douglas fir, Scots pine and maritime pine when the risk of dampening is limited; oak, chestnut and locust, still sapwood-free, when the risk of dampening is greater.
