What it is?

Russian people – often a supporter of traditional construction. If the country house or bath is then from a log, rounded or profiled. But if earlier such houses did relatively inexpensively, because the forests were even debugged, now both the log, and the bar, especially qualitatively processed and dried – the pleasure is not cheap. Therefore, even the most ardent supporters of natural materials are thinking not only about the ecology of construction, but also about its economy.

And here the Finnish construction technology comes to the rescue, which is called “Double Bar”. Of course, while this method is not too common in our country, which is skeptical and with difficulty perceives new foreign technologies, but now there were people who estimated the benefits of such a construction method. A double bar is, in fact, the “sandwich” of two dried profbusyev, in the space between which the insulation is laid. It can be two species – cellulosic or mineral.

EcoWhat use as cellulosic insulation.

EcoCite is used much more often than mineral insulation. Its composition is natural cellulose and antispires with antipirens in a ratio of 4: 1. Antiseptic additives are effective in protection against mice and rats, fungus, rot. In most cases, a boraner acts as an antiseptic. Nipple is needed to reduce the probability of fire and burning insulation. EcoWhat use more often due to its bulk structure. It can be poured or using special devices to blew into the emptiness between two bars.

It is the flowability of eco-boys that helps her fill out the emptiness of any configurations, each gap, a gap. Due to this, the formation of a continuous circuit of insulation. Equouth, among other things, moisture resistant and vapor permeate. Therefore, additional equipment of vapor insulation during its use does not need. To insulate overlapping, the EcoWhat is also suitable, but the floating floor with its help will not work. For the insulation of the roof in the house on Finnish technology in most cases, the Minvata is used.

What is better: double bar or frame?

The technology of “double rack” has plenty of pluses.

  • He does not need shrinkage.
  • Material is easy to transport.
  • You can start construction immediately, the installation is not as folded. Delivery of items is made immediately in the desired size, while all the elements are equipped with fastening locks. Collect the house or bath easily – practically as the details of the designer.
  • No additional equipment for construction work is required.
  • The material is not cracking, does not breed.
  • The structure does not require the arrangement of vapor barrier – the walls “breathe” themselves.
  • No need to use neither interventic seals, nor.
  • In the structure, good thermal insulation, as there is not a single gap.
  • Cover with the construction of a bath or a house is not very difficult, to make it with your own hands can even begin.
  • The material is environmentally friendly, does not highlight harmful evaporation even when heated.
  • Thanks to the small weight of the material, the finished structure is also light. Therefore, it can be put on a ribbon foundation or screw piles, the capital foundation is not needed to lay.
  • The attractiveness of the appearance is an important factor. And due to the availability of emptiness between two layers of the bar, you can hide there wiring and communications lines.

Of course, there are also disadvantages that can not be mentioned.

  • There is a difference in the shrinkage of the external and inner layers of the bar, especially if the climate assumes harsh temperature differences. Therefore, the material should only be used very high quality.
  • Selection of insulation – a very important step. If you make a choice incorrectly, in the structure, at the end of the work it will be cold, and nothing will be changed.
  • The need for mandatory impregnation of each wooden element with special compositions from fungus and mold. If this is not done or do it inexpressive, the wood will deteriorate. Replacing the same items are very difficult, since all of them are clips with the locks.

Comparing the buildings erected by Finnish technology, with frames not quite correctly. All stages of construction differ. The frame structure requires a solid, reliable, well-thought-out pile-screw foundation.

If the foundation seeks even 1 cm, the frame building completely turns and can lose the form. “Double bruus” of this is not necessary, t. To. He is not hard.

In houses and baths, for the construction of which a framework technology is used, it is necessary to equip vaporizolation and, as a result, high-quality ventilation, otherwise the air may become either too wet, or dry. The buildings of the double bar in such do not need, as natural material itself regulates the processes of absorbing or giving moisture.

Frame structures are cutting off walp or chipboard sheets, another sheet material. The composition of each of them is glue, and therefore the chemistry that a person is unsafe inhaled. Houses from a double bar are completely environmentally friendly, they will not be harmful to man. In addition, they are strengthened due to the beams of overlapping, if they are embedded in the walls when collecting the structure. But there is one trick – for this only fully dried wood will fit. Its size must be 160 x 50. Only in this case the deformation will not happen. Despite the fact that the thickness of the carrier bars is only 45 mm, the structure of the Finnish technology is durable, not thrown, do not deform.

Dimensions

In production, manufacturers most often offer mini-timber 45×130 and 45×140 mm. When using a bar of this size, the finished walls have a thickness of from 200 to 220 mm, the insulation layer is approximately 130 mm. Also a bar may have a cross section 44 x 135 mm, 70×140 or 150 mm, 70 x 190 mm, 65 x 142 mm. It is possible to order a domocomplekt for individual sizes, however, it will cost much more expensive.

Each bar must be well succeeded, its humidity cannot exceed 12%. Only after drying to the desired humidity produce profiling on high-tech equipment, after which the surface is subjected to careful processing. The finished material is completely homogeneous – both by structure, and on a shade, and in quality. Connection of parts occurs with the help of the “Schip – Groove” method.

Thanks to a thorough dryer, the finished structure does not form cracks, and its shrinkage is insignificant.

Construction process

Any construction begins with the creation of the project. It is also necessary for the country house, and for the bath, and for summer kitchen, and for any other building. Manufacturers of houses on Finnish technology have ready-made projects (with household complexes that can be purchased immediately). It can be both projects developed by them and borrowed from others. Many firms make it possible to make a minor modification of projects and household complexes in accordance with the needs of the customer, but this is in most cases the construction more costly.

After the project is approved, the creation of the details of the structure begins in accordance with the drawing (It does not matter whether the project was typical or individual). Before building a house, it is necessary to lay the foundation. Let the deep and expensive foundation are not required, but the small-breeding belt is still needed. Or, if the client already has a ready-made foundation, the structure can be collected and on it.

To bring the future house, disassembled to the details, in place of its assembly, no special transport will be required – neither the size nor the weight of the details is small. Build a building too easy. First put the base from the rivers, the first level of the bar is laid out on it. Mounting foam will help close the slit. Next, the grazing is assembly – as in the designer. Because the angles are connected by locks, nor glue, nor nails will be needed. The interventovation compound keeps firmly due to the profile, which is based on teeth and grooves. For one operation still requires special equipment, and a master professional. This is the process of strangling the insulation, which cannot be evenly placed in voids without special equipment.

When the insulation is placed, the log house is assembled, the installation of the roof begins. This establishes a rafter system. Excellent if at the design stage they thought out where communication would be located. At the end of the roof mounting, you can move to the external and interior finish of the house. It should be noted that the bar, which is used in the buildings on Finnish technology, looks attractive and without additional finishes. Therefore, to finish the walls, you can use lescing, tinting or apply lacquered. This will be enough.

As for the treatment with antiseptics and antipirens, it must be carried out during the manufacture of details of the house.

Review reviews

Reviews of household owners and dual bar baths for 90% positive. AND Even those who are not satisfied with the construction of 100%, celebrate heat, dryness, excellent appearance. Residents of the northern regions add that the individual thermal insulation of windows and doors is still required, otherwise you will have to install additional heating sources, which will lead to an increase in electricity card. Owners of houses in regions with temperate climate, on the contrary, noted excellent thermal insulation and reduction of electricity fees. Almost all users note the need to properly choose the insulation, as it plays a decisive role in the answer to the question whether there will be warmth in the house or bath. From the complaints of the owners of the most common is the shrinkage of the structure.

Developer firms promise shrinkage by 2%, but, for example, in the house, a height of 7 m 2% of height is 14 cm, and this is a lot. Therefore, to order the construction of houses and baths from a double bar and experts, and users themselves are recommended only from those developers who specialize in such construction for at least 5 years and have a good reputation in the market. Do not chase at low prices of one-day firms that close a year after the opening. The house is a serious building, expensive. In order not to turn out to be storm, which pays twice, it is better to purchase a little more expensive, but a proven developer who provides a guarantee for its work.
