History of wood as building material

The history of wood as building material is as old as the history of mankind. At the beginning, wood was only easily obtainable and processable material in the nature; later on, excellent qualities of the wood were evident. During the discovering of new building materials and thanks to new development, technical procedures, technologies of industrial processing as well as owing to wood areas decreasing gradually in a drastic way, wood become more and more neglected material. Load-bearing constructions were mostly produced from reinforced concrete or steel components. However, ecologic changes and obvious problems connected with the pollution of environment have been drawing, over the last decades, the attention to the importance of ecologic awareness, people tried to live more in harmony with the nature (For example: culture from the Far East invade the Europe). Perhaps this was the reason why wood as building material has been in the limelight.

Strictly speaking, useful qualities of wood make it an excellent building material. It can be processed in simple and various ways. In the growth direction, it is highly solid, but less in the crosswise direction. It is an important quality primarily during a construction since the producer takes all these aspects into account as a base in the preparing of building construction designs. In comparison with its weight, wood is very solid, it is easily processed and well-combinable material.

In comparison with other building materials, wood is a good thermal insulator, its air-filled cell structure does not dissipate heat. It emerged that wood has a very good fireproof quality. It ignites very long time; its internal layers warm up only slowly during a fire as compared for example with metals that cannot be saved when they reach the melting point. By exposure to fire, external layers turn into carbon, which further increases thermal insulation and prevents the penetration of oxygen into internal layers of the wood structure.

From the ecological point of view, wood is the only renewable source of building constructions thanks to wood planting. For its reproduction, we do not need any fossil energy sources and as it is well-known, wood takes CO2 from the atmosphere during its growth, resulting in the considerable reduction of the greenhouse effect. After its processing, wood is re-used as a raw material for other production or as a solid fuel.

The lifespan of built-in wood depends on professional processing, assembly, treatment and level of dampness. The lifespan of wood that has been professionally treated and built in a construction may be in the range from 100 to 150 years, without any damage or impairment of static qualities. Wood creates a pleasant atmosphere in the interior, combines well with materials of other types when furnishing spaces and it is in again.
