Advantages of Wooden Houses. Wood Properties

When planning the construction of a house, everyone is faced with the problem of choosing the main building material. Of course, in all there are pros and cons. The main thing is to decide on your priorities. Monolithic buildings have the greatest strength and durability, but contain a lot of substances harmful to humans, therefore they are not suitable for private home ownership. Stone and brick, although not so harmful, but laborious in construction. Yes, and are expensive. It turns out that for low-rise construction, wood is best suited.

Let us consider in more detail the advantages and disadvantages of wood as a building material. Let’s start with the disadvantages:

  • Wooden houses are not suitable for multi-story construction
  • Mold, fungus forms in the wood; bark beetles appear
  • After getting wet, the tree swells
  • Long shrinkage, which can lead to warping, cracking of walls.

However, only the first can be called a real flaw, because modern technologies have long learned to fight the rest. And since we are not talking about apartment buildings, it turns out that for low-rise construction, the tree is ideally suited.

But let us dwell in more detail on the properties of this material.

The most useful and most familiar quality of wood is its ability to purify air. How does this happen? Wood fibers pass street air through them, trapping dust. Moreover, they secrete particularly useful biologically active substances – volatile, which have antibacterial protection. Due to the fact that volatile substances belong to volatile substances, they exert their effect at a distance. So, pine volatile production can “kill” Escherichia coli and the causative agent of tuberculosis. In Japan and South Korea, even doctors prescribe for their patients the so-called “bathing in the forest” – the inhalation of substances secreted by trees. Thus, the property of air purification favorably affects the health of people living in a wooden house.

The next property is humidity regulation. The trunk of the tree contains capillary and hygroscopic moisture. After the felling, the capillary gradually dries completely, and remains bound (hygroscopic). This moisture dries longer, and only to a certain limit. In the end, wood acquires a property called hygroscopicity. It means that with excessive humidity, the walls of a wooden house dry the air, absorbing moisture. Conversely, when the air is too dry, they “return” moisture to the inside. As a result, the house always has an optimal level of humidity. By the way, back to the mentioned disadvantages. Prolonged drying after construction can be avoided, as well as swelling. For this, even at the stage of manufacturing the material, the logs are placed in a special chamber, where they are subjected to uniform drying. And after the walls are erected, the logs must be treated with special means that protect them from environmental influences. Such coatings form a very thin, but dense film that does not clog the wood and does not deprive it of its beneficial properties. In the same way, wooden houses protect against a possible fire. For this, fireproofing agents are used. Another great option to avoid warping is to use dry pine in the construction. This tree dries up standing on the vine. Moreover, such natural shrinkage lasts about 150 years, giving the trunk more and more strength. Therefore, dead wood is very much appreciated.

Another important quality is low thermal conductivity. Wooden houses are much warmer than brick or monolithic. Wood is even used as insulation. With increasing humidity, the thermal conductivity increases, that is, their thermal insulation property decreases. A wet tree can no longer give you warmth, so it is important to protect the walls of the house from rain, snow and high humidity. This can be achieved with a bioprotective coating.

And finally, let’s talk about caring for our wooden house. Over time, cracks appear in the logs – this is normal. But, if you do not treat the crack with an antiseptic, it will soon cause a fungus or mold. In principle, it is enough to inspect the house 1-2 times a year, preferably before and after winter. This will be enough for the tree to serve you for more than one century.
