Articles about the construction | The advantages of wooden materials Anyone who decided to go in building a house or cottage, you want it to long standing and well served.The traditional material for the walls of old low-rise buildings is a tree. Wood as a material has many important advantages. Wood is fairly easy to "stick together", easily connects 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 metals. The walls of your home or cottage must be durable, have good sound insulating qualities, have, perhaps, less weight, to provide a constant indoor temperature required for the building.

Its disadvantages are the only sedimentary deformation in the first year or two, and low fire. However, now with both disadvantages can be overcome. To improve the fire resistance using special equipment, which is impregnated wood. This allows the fire to increase to such an extent that even at high temperatures, the tree will smolder, not burn. The most comfortable on the sanitary-hygienic requirements (including having low thermal conductivity) are cobbled and chopped walls of coniferous trees.

Coniferous trees are more suitable than hardwood for the reason that they have a more regular shape of the trunk and less prone to decay.

The main parameters that determine the longevity of the tree are:

resistance to cracking
resistance to decay
low knotty
low hardness
high taunt

The strength of wood is determined by the breed of tree density, moisture content, presence of defects.

Humidity is the free and bound. Feature of the free moisture is that it evaporates from the wood very easily. To test this, just remember that the rain soaked wood dries fairly quickly, within a few hours. Associated moisture, on the contrary, evaporates slowly, and in order to dry the wood, without resorting to the help of special technology, can take several years. As the number of bound water is less than the strength of the wood. When moisture enters the limit of water absorption (30%), moisture is no longer influence the strength of the wood. In addition, the practical value of the difference between free and bound moisture is that the evaporation of the first changes only the severity of the tree, while the second varies the amount of evaporation, ie, shrinkage occurs. Reducing the amount of wood at its drying varies in different directions. As the thickness is greater than the length. The table tree species were divided into 3 groups according to the coefficient of volumetric shrinkage.

When drying wood moisture evaporates evenly. First, moisture evaporates from the outer layers, and then from the interior.
Malousyhayuschie spruce, fir, cedar, white poplar, pine, etc.
Sredneusyhayuschie oak, elm, beech, aspen, ash, black poplar, small-leaved lime, etc.
Sredneusyhayuschie platanoides maple, hornbeam, larch and birch.
This is not a uniform evaporation of moisture leads to what occurs in the wood inner tension, pulling it to the surface and inside the contraction, resulting in a tree may appear cracked.

With the density and moisture content of wood is closely related to the ability to hold its own metal fasteners. The higher wood density, the higher the resistance pulled out a nail or screw. Humidity makes driving nails into wood.

Hardness - the ability of wood to resist the penetration of solids. According to the degree of hardness tree species can be divided into three groups:

Soft pine, spruce, cedar, fir, aspen, linden, alder, and poplar.
Solid birch, beech, elm, larch, ash, elm, elm, maple, apple.
Very solid Hornbeam, dogwood, boxwood, locust, and birch.
Durability of wood - is its ability to resist destruction in the process of friction. Here there is a pattern: the higher the hardness and density of the wood, the less wear.

Rot is the result of activity of different fungi that destroy wood, and in most cases make it unfit for work.

Knotty - the presence of base branches (twigs) of living or dead during growth. Violates the uniformity of the structure of knotty wood and reduces its strength, makes it difficult to process. Easy - the property of wood, which is advantageous in the construction, in combination with other qualities. about the advantages of building homes or cottages is pine. Our company is engaged in building houses cobbled pine. The advantages of wooden houses you already know, I would like to talk about the advantages of a separate building houses or cottages is pine.

Дійсно, дерево має надзвичайно багато переваг в порівнянні з іншими матеріалами. Його можна використовувати практично всюди, від будівництва будинку до елементів декору. Тим паче,що зараз в тренді використання натуральних матеріалів в оздобленні.. Одним словом, незамінний матеріал.
