Compared to its weight, wood is the best building materials. Long held in his only appearance, wood resistance is increasingly evaluated according to scientific methods to use with an optimum level of safety and efficiency. The wood is resistant to shock: The wood subjected to impact or blows undergoes only insignificant deformations not affecting its function. It also absorbs shocks and causes the objects that strike the less serious damage than a material harder.

At low temperature, the wood does not become so brittle at high temperatures, resistance remains intact and on about his relatively constant volume. Combined with a high capacity for storing and heat to a very low coefficient of conductivity, these properties make wood a temperate material in all climates. It is also used in some local chilled as cold stores, or strongly heated like pools.

The wood does not emit any radiation, the man has nothing to fear from materials with very low radiation are aligned with those of his own body. Note also that the wood does not destroy totally the magnetic field of the atmosphere, as is the case for example of reinforced concrete that sustains man in a dead field. Finally, unlike almost every other building materials, wood absorbs and releases moisture from the air, thereby regularizing the environment.
