 * Wood is a hard, fibrous tissue found in many trees.
 * It has been used for hundreds of thousands of years for both fuel and as a construction material.
 * It is an organic material, a natural composite of cellulose fibers (which are strong in tension) embedded in a matrix of lignin which resists compression.
 * The earth contains about one trillion tonnes of wood, which grows at a rate of 10 billion tonnes per year.

 * for its favourable relationship between density and strength,
 * for its low thermal conduction,
 * for its acoustic qualities,
 * for its elastic qualities.
 * it neither gives off harmful substances nor causes allergies,
 * it balances the humidity in the air,
 * it is antistatic,
 * it is not radioactive.
 * wood is the only renewable building material
 * wood allows for the highest degree of prefabrication and rapid assembly,

EXAMPLES media type="file" key="EXAMPLES.mp3" width="240" height="20"
 * The history of wood construction can be traced consistently in China, Korea, and Japan and in the domestic architecture of northern Europe and North America
 * The most representative exponent of building with wood in our country has been the architect Fruto Vivas.
