On the remarkable properties of wooden houses, we can read in the brochures of any companies that specialize in the construction of the timber. According to some construction companies, then almost all of our winter ailments - from what we do not live in the wood, and stone houses. Wood - this is a good thermos, allowing to keep warm, and natural air conditioning, providing a healthy climate in the cottage, as well as saturating the air sweet smells ... A special category of "Wooden myth" - a winter forest. Representatives of companies and cooperatives that specialize in hand-chopping, argue that the building needs only from logs harvested in the winter. Finally, the wood - a material not only "alive" and quality, but affordable.

Choosing a cottage, the citizens of our country to be guided home of ceramic blocks and bricks, the materials on the basis of the foam and aerated. Houses made of wood, and even more frame houses with wooden frames, are associated with economy-class villas da shack. And, apparently, there are two reasons. First, the quality of wooden houses are not always consistent with what the manufacturer promises. Secondly, marketing, promoting brick and aerated concrete - are working luchshe.Odnako, unlike us, the United States the lion's share of low-rise housing given to homes with a wooden frame, in Europe, houses made of wood have a lot of fans, and in Japan, this wooden house, delivered from Finland, can afford only a very wealthy gentleman. Let us examine the basic myths that emerged around the wooden house.
The first myth: tree - the most eco-friendly materials
This is not a myth, but the truth. However, the "environmental friendliness" a wooden house, which is spoken by all, without exception, manufacturers can easily be reduced to nothing, if applicable fine impregnation based on the toxic solvents, preservatives, fire retardants, compounds used in the manufacture of laminated veneer lumber, insulation mezhventsovye. Finally, even log houses require insulation gables and roof space. And here are in the course of mineral wool, wood fiber plates (from different manufacturers, including those not always honest), as well as all kinds of certified and uncertified foams and expanded polystyrene, which at best - allergens, in the worst - have toxicity.
Myth Two: The wooden houses are short-lived
According to the literature, with the right technology subject to the life of wooden house - 50 years old, brick - 80 years. But this is not an axiom. There are brick structures, which are scattered over the decades, at the same time as some of the country houses of the past centuries have been preserved in such a condition, as if built yesterday. Any home requires care. He lives as long as it lives and maintain it in proper condition. Abandoned building of brick and aerated concrete blocks in our humid climate, where temperatures are constantly in the off-season rides through the ruinous for any materials "zero" mark, also deteriorating rapidly. This condition may be irreversible. The durability of wooden houses depends on the choice of the construction of antiseptics and flame retardants, wood quality, correct installation of insulation, engineering systems, ventilation and waterproofing of the basement.
We fear that the wooden structures strike mold, mice and insects. But the problem is not just a timber. Fungi also destroy and concrete, and brick, and polymers. Meanwhile, the modern technology of wood processing, using compositions having a biological basis, reduce the risk to a minimum, but the rise in demand is another myth is processed - and forgotten. But in most of the instructions for use of antiseptic formulations states that treatment should be repeated four or five years.
Myth Three: wood "breathes"
It seems that this is not a myth. Experts say that the timber accumulates the heat and the temperature usually has a couple of degrees higher than all that surrounds it. It has exclusive steam and air permeability, so the wooden house, as it were samoprovetrivaetsya, air-conditioned, but it keeps you warm and natural for a person level of humidity. A 'wooden' ability to breathe, in turn, reduces the risk of mold and putrefactive bacteria. Of course, if provided the opportunity for a "breathing", namely, high-quality ventilation (by the way, a wooden house in need of extremely high quality and sophisticated ventilation system - but it's a topic for a separate publication).
What does the home experience? Many wooden houses really breathe, but not because of the "magical" properties of wood, but due to ventilation by the corners and joints mezhventsovyh. To see this, it suffices to thermal imaging survey of modern log houses.
Builders in one voice say that the thicker the walls, the warmer the house. In fact, it is important not so much the thickness of the logs, but the fact of how much wood is chosen to put them on each other. In the timber wall at the junction always get thinner. Meanwhile, there are norms of the sample, but some builders use our ignorance. For example, if the height of the walls of your house 2.5 m, then it need not ten logs with a diameter of 25 cm, and with the sample - eighteen. An unscrupulous builder "save" on Steciw and will cost fifteen. Then the "breath" is provided. On the thermal imaging picture seen as reliable and solid walls of a calibrated timber loses heat. Protopit a house - no problem, but it cools rapidly.

Myth Four: wooden house fire risks
Any house burn, and it is a sad reality. But for some reason, potential homeowners are convinced that this wood-frame houses, and in this respect is most dangerous. And if it were not for this phobia, the fans at the wooden house would be much greater. And purchasers of apartments in the city is not the old fund would prefer the metal floor beams of wood.
Incorrectly built house, if his master on the fire spared the measures can burn in minutes. I once had occasion to observe how the new hut burns: the air gaps between the insulation and facing the fire spread quickly, as in the turbine, and the sawdust swept migrant workers under the floor, breaking out, like gunpowder. But for some reason, believe that the wooden house burned down and a brick after a fire can be restored. This is not true.
When construction is very important to keep a set of fire safety measures. Wooden elements in problem areas such as around chimneys, should be treated with flame retardants. In addition, strict adherence to the rules of installation of furnaces, chimneys, heating and electrical systems - they are the main "hot spots" that lead to fires.
Meanwhile, a statement that the wood burns better than other materials, is proving to be problematic. In fact, a wooden beam in a fire resistant than metal. When the critical temperature, the metal melts and changes shape, resulting in metal construction, especially loaded with concrete slabs may collapse much earlier wooden. A long wooden beam bearing capacity remains: to fail, it needs to burn about half, and during this time may have come in time and fire. In addition, burning difficult and the resulting ash. Yes, and set fire to the wood, especially treated with flame retardants, the problem is not so, and simple.
Many more complaints from representatives of the fire control is used as insulation foam and internal structures goryacheformovannyh penopolistrolov. They should not coexist with wood paneling. Although these materials, according to the manufacturer, "does not support combustion," but in the event of a fire is quickly building a poisonous cloud over the smoke. Strictly speaking, the premises of such a construction should not be taken in the fire service, but the "dacha amnesty" allows you to build a fire risk giving all the time. And this is a sad fact.
Myth five: winter forest
As soon as spring comes, as in our gardening will be many announcements of proposals for the construction of the so-called "winter forest". "Winter" and "northern" forest - is another source of in demand "wooden" myths and legends. Some of our builders believe promorozhennaya wood the best material for construction, while others argue that it is just a marketing ploy. According to them, in the winter in the villages were built just because the summer peasants engaged in agriculture, and to export the logs from the woods on the frost-bound soil - it was much easier. Nevertheless, this myth is under a truthful basis.
Indeed, the tree does not grow in winter and autumn flushes excess moisture. Many fans are built from the slow-growing and very dense, or Lapp Archangel pines. But here we must bear in mind the following. First, who among you can tell the real from the northern areas affected by fungal diseases of our north-west? Second, is there any guarantee that the trees that are being offered as a "winter" has not been felled in the autumn and left to plot to spring? Practice shows that it is just the winter construction is often of the "old" wood. Only in the course of the summer can go "winter". Anyone who wants a house is from the winter wood must not be interested in a period piece, and the conditions in which the timber was stored prior to entering the construction site.
