Thermobar - a unique solution for building an energy
More and more compatriots are showing interest in building a house from a thermo-bar. And this is not surprising, since many perceive thermobar as a building material with the use of which they build the most energy-efficient houses to date. Is it really?
Construction features
Heat-saving lumber is a relatively new development designed for the construction of high-quality low-rise buildings in a short time.
In fact, thermobar is a complex structure consisting of wooden lamellae and a layer of insulation. All elements of a single structure are glued together with special compounds that provide a strong, almost monolithic connection.
Materials used
Coniferous, mainly hardwood boards with a thickness of 80, 60, 50 and 40 mm are used for the production of lamellae. As a heater for timber used polystyrene foam. However, the choice of filler for such structures is great, and you can buy exactly what corresponds to the needs of the construction.
For the first time, the construction of houses from a thermo-bar was carried out about 30 years ago and since then has not lost its relevance. At the moment, as the main building material, profiled glued bars with a layer of insulation are used.
Main advantages
The choice of this material is not accidental, because it is a thermal bar with a glued structure that provides many different advantages, including:
- optimum degree of humidity (no more than 14%);
- resistance to the negative effects of environmental factors;
- lack of need, both in internal, and in exterior finish;
- biological safety (material is not subject to rotting and the appearance of pathogenic microorganisms);
- fire safety due to flame retardant treatment;
- a log house is not prone to intense shrinkage (no more than 1%);
- stability of sizes and shape of the finished building;
- resistance to mechanical deformations and, as a result, the absence of cracks;
- thermal bar has low thermal conductivity and, as a result, high energy efficiency of the finished house;
- more affordable cost of building material in comparison with solid sawn timber.
Technical and operational characteristics
Do you decide to purchase timber from thermotree or opt for more traditional materials? It should be understood that it is a multi-layer construction that is able to provide the minimum degree of thermal conductivity of walls. As a result, when operating the house, it will be possible to save money on heating the premises in the winter and on their air conditioning in the summer.
A modern thermal bar is made from dry wood that has been treated with flame retardant and antiseptic compounds. Consequently, a house built of such material will be resistant to fire. In addition, a variety of microorganisms will bypass your house side and the walls will not be subject to rotting.
Such advantages make the house of the thermo-bar and log not only optimally adapted for all-season living, but also durable. If the construction is followed by instructions and all technological requirements, such houses without the need for repairs can be operated for decades.
Another important advantage of this building material is the stability of the geometric dimensions. Unlike traditional sawn timber, glued bars are able to maintain their original shape and size for as long as possible.
The thermobar with glued lamels practically has no shrinkage. As a result, the built wall will remain intact and level. The fact is that glued wood does not bend or twist. Firstly, this is due to the fact that the material is dry, and secondly, the structure of laminated wood eliminates the formation of internal stresses.
Wall thickness calculation
If you decide to build a house with your own hands, initially calculate the thickness of the walls in order for them to ensure optimal energy efficiency of the future home. Properly compiled estimates for the initial pores will determine how costly it will be to build a house and how profitable will its operation be.
The calculation of wall thickness is carried out in accordance with the standards given in SNiP II-3-79 "BUILDING HEATING TECHNOLOGY". Listed here are data on the degree of thermal conductivity of lumber and the values of thermal resistance for different regions. Multiplying these parameters, you can get the nominal coefficient of thermal conductivity.
Since the thermal bar is made using coniferous wood, the value is calculated for pine and spruce across the fibers. In this case, the degree of thermal conductivity is 0.15 W / (m. C). This number is multiplied by 3.15 (the values of thermal resistance for the Moscow region) and we get 0.47 m.
The resulting figure complies with the requirements of GOST 8486-66 and GOST 9463-72. Thus, a 47 cm thick thermal bar with lamellas of laminated wood will be the best solution from the point of modern building standards. Moreover, this thickness will be quite enough in order to do without additional insulation.
Important: the use of solid wood with a wall thickness of 47 cm does not meet modern building standards, and therefore requires the need for additional thermal insulation.
Conclusion
From the above, a number of conclusions can be drawn, namely: a thermal bar is a real opportunity to build walls of small width with optimal thermal conductivity parameters. Thermobar can be used for walling both in temperate regions and in conditions of the Far North. In addition, this building material has an affordable price and it demonstrates the optimal combination of better quality and ease of use.
Thermobar has low weight in comparison with traditional building materials, as well as with solid logs and bars. As a result, the construction of a house can be managed not only quickly, but also with the involvement of a small number of employees. Of course, the rent of lifting special equipment for the construction of such houses is not needed, which favorably affects the cost of finished construction.
