General information

General information: Wood is a set of xylem formed by roots, trunk and branches of woody plants, the bark is not part of this set. Wood is anisotropic and hygroscopic material with good mechanical properties and easy to process, and soak machined also has a special beauty. For this reason it is the only material that has been used since prehistoric times, for the protection of wood has been treated since 250,000 years ago (it heated the fire to harden).

Wood is a living being and their physicochemical properties depend on their cell walls are composed of three layers (S1, S2, S3), the walls that serve as nutrient xylophagous.
