Eternal wood classic traditional material for wall low-rise buildings is a tree. Wood as a material has many important advantages. Wood fairly easy to stick together, without much Labor joined with nails, screws, etc. She is well handled and lends itself to decoration. In terms of the ratio of the density and strength of wood can be compared with metallami.Steny home should be durable, have good sound insulation qualities to have, perhaps, less weight, provide permanent facilities in the temperature regime required for the building. Its drawbacks are the only sedimentary deformation in the first 1.5-2 years and low fire. However, now with the two drawbacks can be overcome.
To improve the fire resistance using special equipment, which is impregnated wood. This allows a greater fire resistance to so much so that even at high temperatures, the tree will smolder, not burn. Most comfortable for the sanitary-hygienic requirements (including having a low thermal conductivity) are cobbled and chopped out of the wall coniferous trees. Coniferous trees are more suitable than the leaf on the ground that have a more regular shape of the trunk and less prone to decay. The main parameters that determine the durability of wood are: * Strength, density, resistance to cracking, resistance to rot * durability, low knotty, low hardness, high barb * ease. The strength of wood is defined types of wood, density, moisture content, presence of defects. Humidity is the free and bound. Feature of the free moisture is that it evaporates from the tree very easily.
To test this, it suffices to recall that soaked in the rain tree dries out fairly quickly, within a few hours. Bound moisture, by contrast, evaporates slowly, and in order to dry the wood, without resorting to the aid of special technology, can take several years. As the number of moisture-related durability of wood is getting smaller.
