Wood is one of the oldest building/construction material and despite the evolution of the other competitive materials, it continues to preserve its value in many traditional usages. There is a gradual increase in the production of new wood material. This is due to the unique advantages it has in comparison with other constructive material:   

• Wood is extremely friendly to the environment
• It is renewable, natural organic material
• Aesthetically unrivaled, with a wide variety of colors, texture, design
• It provides a feeling of  warmth to the touch and vision
• It has a great mechanical resistance in comparison to its weight
• It is insulating to heat and electricity
• It can be processed with a small energy consumption
• It is easy to put together
• It does not pollute the environment
• It binds large amount of carbon

As a biological material, it has variable structure and its quality is influenced by hereditary factors but also from the environment where it grows . Also, it is a hygroscopic and anisotropic material, it burns and rots.

Improving the quality of wood is very important because:                                                

• increases exploitation possibilities
• improves the quality of constructions
• provides economic benefit
• reduces errors and misplacements
