Houses using the double beam system. Finnish technology double insulated timber TsPSB. Video - Owner's review of a house made of double timber

The season in which timber is harvested for the production of Double Beam houses does not matter for our customers, because:

All wood selected for the production of house kits undergoes a chamber drying stage to a moisture content of 10±2% in specialized drying chambers. It is noteworthy that, according to various studies, wood moisture content in the period November-February is the highest of the year, contrary to popular misconception, and wood reaches its lowest moisture content in July-August.

All natural moisture lumber is stored in ventilated stacks in an open area, which prevents the development of blue stains and fungus in the summer.

All materials that have undergone the chamber drying stage, including mini-timbers and finished house kits, are stored in a closed dry warehouse, which guarantees the safety of the wood from waterlogging when exposed to precipitation, from darkening when exposed to ultraviolet rays, as well as from other types of damage.

* If you still want to build a house or bathhouse from Double Beam from winter forest, then you must have time to conclude a construction contract no later than the end of April, this is worth keeping in mind!

Construction of a house using technology double beam

Double timber - comfortable inexpensive housing

The main problem of wooden cottages is the need additional insulation walls in the Russian climate completely solve double timber houses with internal thermal insulation. Minimal shrinkage in combination with prefabricated house kits and no restrictions internal layouts makes the technology in demand among individual developers.

Nuances of the technology of building a house made of double timber

The inventors of the wooden house-building method are Finns. The name should have been renamed “warm prefabricated timber”, but this is the name that has taken root in Russia.

Therefore, each individual developer receives the most detailed advice on the materials and structure of the “pie” of walls. The designers took all the best from the technologies of log cottages and SIP panels, eliminating their shortcomings almost completely:

    wall thickness is adjustable - you can apply any layer of thermal insulation for a specific region of operation and select the thickness of the tongue-and-groove board with a specific bearing capacity and strength characteristics

    reduction of energy-intensive work - cutting bowls for corner joints of crowns in a board is much easier than in an array of planed or laminated timber

    fire safety double timber houses- unlike SIP panels and classic “warm” timber, non-flammable ecowool is used

    saving materials and construction budget - wall light material, a massive foundation is not required, there are no dowels and inter-crown insulation, window and door blocks mounted without casing

    reduction of construction time - no special equipment is needed to assemble walls from boards

    adequate for double timber price- due to cheap raw materials, reduced labor costs, and the use of pile, columnar and shallow strip foundations

When using standard timber, the building is insulated from the outside; the thermal insulation, in turn, must be protected from wetting and weathering, and the facades must be given the necessary decorative style. Therefore, systems of wet and ventilated facades are added, which dramatically increase the construction budget.

Unlike the outer surface of SIP panels made of OSB or timber, in which cracks open over time due to internal stresses, edged polished boards double beam technology It is quite suitable as an independent external and internal finishing coating.

Production of houses from double timber

The construction material of this technology is board. Therefore, increased demands are placed on the quality of lumber:

    Made from pine - low percentage of knots and other defects, stable geometry and low internal stresses

    humidity - lumber has an acceptable 12 - 14%, which allows you to do without chamber drying, but maintain the main characteristics and reduce cost

    grade - only A and B with smooth front surface

    thickness - 44 mm or 70 mm for making grooves and ridges, cutting out bowls corner connections

Decreases by double timber price using automatic cup-cutting lines. The entire technical process is divided into stages:

    workpieces are fed onto the conveyor

    technological holes are drilled

    bowls and grooves for casing are cut

    lumber is cut according to the design

    cutting waste is removed

    marking is applied

    products are packaged for storage and transportation

Technology of constructing a dwelling from double timber

Despite the fact that the thickness of the walls can vary within any limits, the territory of the Russian Federation is located in several climatic zones with known operating conditions and negative temperatures in winter period. Therefore, for the convenience of developers, several standard options are usually used:

Options for external walls wooden houses made of double timber


For buildings for seasonal use and internal partitions - for garden house no heating and no load-bearing walls cottage, dacha, it is more rational to use 44 mm or 70 mm tongue and groove boards without insulation


warm climate, " mild winter» - wall thickness 188 mm or 238 mm from 44 mm boards and 100 mm, 150 mm ecowool layer between them, respectively, the option is also suitable for partitions

The thickness of the insulation is 100 or 150mm. The total thickness of the house wall is 188 and 238 mm, respectively.

This option is used for the manufacture of walls and partitions of residential wooden houses.

This design has become most widespread in the construction of residential wooden houses.



harsh climate, critical levels of negative temperatures - 240 mm or 290 mm walls made of 70 mm calibrated boards on both sides and 100 mm or 150 mm of insulation inside the warm timber

Production of houses from double timber provides the developer with a house kit, that is, a set of marked boards from which the building box must be assembled on the erected foundation without errors. That's why “Double beam” technology complex, combines the construction of a log house and the classic “framework” with minor differences:

    instead of a log or beam, the crowns consist of two parallel boards installed on an edge

    the corners retain cuts, but the crowns have a hollow structure like a frame without posts

    after the construction of all floors to the mauerlat and gables to the ridge, the space between the boards double timber houses filled with ecowool

Exactly final stage is considered the most important, affects the operating life and can become a source of increased operating costs when self-insulation. The fact is that specialists from specialized companies use professional technologies:

    industrial equipment for the production of ecowool and its supply under pressure of 2 kg/cm 2

    calculation of the density of the heat insulator depending on the height of the “frame structure”

An individual developer who does not have such equipment will be able to insulate with commercially available heat insulators:

    extruded polystyrene foam - does not meet fire safety standards, according to SP 4.13130, the wall perimeter adjacent to window/door units should be insulated only with non-combustible materials

    basalt wool - complies with fire safety standards, however, with high wall heights it is guaranteed to shrink without vertical fixation to load-bearing structures

    glass wool - similar to the previous case, the owner will receive crumbling insulation from below and empty space at the top of the wall after 4 - 7 years of operation

That is why production of double timber houses their assembly at sites must be carried out by specialized companies.

Price analysis or double timber versus other technologies of wooden architecture

To compare efficiency different methods construction of a wooden cottage, specific prices for 1 m2 of living space should be abandoned. Because this value is too uneven across regions. It is enough to understand at what stages “Double beam” technology allows you to reduce the construction budget and operating costs:

    Insulation:

Even when using 2 x 2 dm timber, additional heating will be required in winter, heat loss through the enclosing structures and energy consumption will increase. Therefore, both log houses and houses made of timber are additionally insulated from the outside; this is not relevant for double timber, as well as for frame construction.

Standard crowns made of calibrated timber/logs are insulated with flax, which is added to the cracks during caulking after the house shrinks; these costs are not included in the technology under consideration.

    Decoration:

There are no ventilated or wet facades, the purpose of which is to decorate the heat insulator and give the facades original design. On double timber price automatically turns on the internal and exterior finishing, the board does not crack and retains an attractive appearance on par with a block house or clapboard.

    Foundation:

Prefabricated loads at production of double timber houses much lower than in log houses. You can get by with columnar and pile grillages, if you need a floor on the ground, use a floating slab or MZLF.

Assembly takes a few weeks in almost any weather, since the cavities between the boards of double timber are filled with insulation at the last moment in one day. The tongue-and-groove lock guarantees no blowing and minimal shrinkage within 2 cm/m of the height of the house. The bowls of corner cuts are milled on machines and have precise geometry, in contrast to similar connections between timber and rounding.

Thus, double timber technology allows you to reduce the construction and operation budget ultimately after finishing and wiring of communications. To be fair, the disadvantages of the method should be noted:

    zero repairability of the walls - due to insufficient experience in operating buildings, it is not clear whether it is possible to raise the “frame structure” to replace the lower, usually rotting, crowns

    shrinkage of insulation - only when the individual developer uses the materials indicated above

Due to the insufficient service life, reviews of double beam technology are extremely positive. If technology is followed, all of the above disadvantages are compensated by adequate cost square meter, high performance. Therefore, the technique has many more supporters, and it is gaining popularity every year.

Even a novice builder knows that log houses have two main drawbacks - thin walls and shrinkage of the crowns. The latter occurs due to wood shrinkage. Therefore, they use techniques that prevent wall deformation and promote it. effective insulation. According to existing standards, the walls of a house should be no thinner than 20 cm.

The double beam technology, which was first used by Finnish builders, allows us to solve this problem. The country has a small number of trees thick enough that could be used to build houses, while protecting them from the severe frosts characteristic of the region.

What is the essence of the new technology?

Finnish engineers have managed to develop a technology that allows them to build warm wooden houses at relatively low financial costs. It was called “double beam”. In fact, this technology has little in common with timber in the usual sense. Its essence lies in the fact that to achieve the proper thickness of the walls, two tongue-and-groove boards are used, between which there is a layer of insulation.

Houses using double timber technology are distinguished by improved thermal insulation characteristics, compared to houses from solid timber similar section. Compared to insulated laminated veneer lumber, this technology does not use adhesives. The insulation is often ecowool or mineral wool.

Double beam: production

The production of material for the construction of houses using double-timber technology differs from the production of conventional profiled timber. It is carried out on special equipment - a fully or partially automated cup-cutting line.

It is carried out in several stages:

  • production of workpieces;
  • drilling holes intended for fastening edged boards;
  • cup cutting;
  • grooving;
  • cutting the workpiece;
  • removal of residues;
  • marking;
  • insulation with material;
  • package.

Advantages

The main advantage of a house made of double timber is high energy saving. The thickness of its walls does not depend on the diameter of the log or timber. The insulation layer is selected in accordance with the requirements specified in generally accepted thermal engineering standards. The second advantage of the technology is the minimal shrinkage of the walls, fluctuating in the range of 1-2%.

You can begin full operation of a house built using Finnish technology once the walls and roof are assembled. Ordinary houses You can’t use it from timber right away, since you need to wait until the wood dries and the crowns “fall” into place. In this case there is no need to wait.

Installation of a house made of double timber is relatively simple, not labor-intensive and does not require the use of complex construction equipment, which has a beneficial effect on the construction time of the house and financial costs. In parallel with the assembly of the walls, they fill the space between the boards. made of double timber there is no need to additionally insulate and finish it.

Flaws

“Double beam”, despite many advantages, also has a number of disadvantages. The most significant is the shrinkage of the insulation, but it occurs only when using mineral wool. There is also the possibility of cracks appearing.
They can form due to uneven shrinkage of the cladding of external and internal boards used for houses built using the “double beam” technology. Reviews from builders assure that in practice such problems do not arise at all. At least there were no comments.

Application experience in the domestic market

The technology has been used on the domestic market only recently, so no one can guarantee that wooden houses will fully perform their functions in our climatic conditions. You just need to trust the Finnish experience in house building, since they have been building houses from double timber for over 20 years and successfully operate buildings in their more severe climatic conditions.

It is not possible to build a house yourself using this technology, since its high-quality construction requires boards processed on special machines. It is also necessary to cut tenons, grooves and docking recesses intended for corner joints. There is no way to do it without a team of specialists and the purchase of a house kit. Therefore, saving on financial costs is problematic.

Structural strength

Double beam technology is not comparable to conventional frame construction, where the insulation is between two thin walls. In this case, everything is held on the bars. There is also a subtype of this technology - “double mini-beam” - that exists and is used. Its construction is similar, but its walls are thinner.

Increased structural strength is also ensured if they are embedded into walls during the construction process. The technology can use exclusively dry lumber, which largely affects the strength of the house as a whole. This is due to the fact that drying the timber leads to a loss of 13% moisture content, due to which the molecular bonds are broken. In the future, the timber will give off exactly the same amount of moisture that it will absorb. Therefore, no deformation will occur.

Vapor barrier

For the construction of houses whose walls consist of several floors, vapor barrier is an important issue. Without its consideration, it is not recommended to carry out construction. Double timber is an exception, despite the fact that the walls of houses built using this technology will inevitably begin to absorb moisture after a certain time. Therefore, there is an opinion that the insulation between the beams is a place for rot to form. Wherein construction companies, who specialize in building houses using this technology, claim that double beams have never caused any problems before. Reviews from the owners agree that it is enough to use the film only in ceilings.

But there are exceptions. Some owners are concerned about the lack of vapor barrier as such, so during construction they use a windproof membrane, which is applied after the insulation. Experienced builders are skeptical about this, since it will not allow the walls to “breathe” freely, but they can last much longer.

Ecowool as wall insulation

When building is not impregnated with harmful synthetic resins, the best option will be the use of harmless insulation. Optimal material is ecowool, the main component of which is cellulose. It does not rot, does not shrink and is not subject to fire.

The calculations for the material are as follows:

  • acoustic insulation - 46 dB;
  • dew point - under standard conditions, condensation will not occur;
  • insulation - 0.13 m2 for every m2 of wall;
  • thermal conductivity coefficient - 0.2 W/m 2.

Ecowool is blown dry into the space between the beams. The height should be no more than three meters. The procedure is carried out in stages. But here certain difficulties arise: ecowool is blown into the “double beam” in the same way as inside frame walls. If the latter have closed wells and it is not difficult to achieve the required density, then more material is filled in and, as a result, can settle. Experienced builders have found a way out of this situation and use a special blow molding installation. Recently it has found great use mineral wool.

Mineral wool as insulation

The material is reliable, environmentally friendly and relatively cheap. If mineral wool is used as insulation, then it is necessary to organize a vapor barrier for the room (this is not done for ecowool). In addition, over time it cakes and, as a result, empty cold cavities form in the walls. Therefore, the material will have to be coated with an antiseptic inside and outside.

Sawdust

It is recommended to use old sawdust to insulate walls. If you only have fresh ones on hand, you can soak them in lime for a day and only then knead them. The procedure is as follows: m 2 sawdust and two bags of cement are poured into the mixer. Moisten everything a little, mix it, pour it into the space between the walls and tamp it down. A significant disadvantage of the material is mice, mold or dampness.

Bulk pulp

The material effectively performs the task of wall insulation. Often, during construction, insulation is not used at all, since they believe that air itself is an excellent insulation agent. But it is important to understand that it serves as thermal insulation only when it is motionless. This is the task of other materials: they create big number cavities with “stationary” air.

Polyurethane foam is sometimes used, but it is relatively expensive, so it is not widely used in construction. In this case, the material releases toxic substances and after a certain time is destroyed.

Box-shaped walls are insulated using flax fiber. Chopped straw or other material that does not cake over time will also work. It is also important to remember its compatibility with wood.

Hello, we bring to your attention Finnish technology wooden house construction"double beam". All production is located in Orel and we are manufacturers.

The wood used goes through several stages of processing: First, the wood is sawn using a high-precision disk sawmill, which provides it with ideal geometry. Then the entire timber with a humidity of 40-60% is laid in a modern drying chamber, where it dries to a humidity of 10-15%! Such material will last at least 50 years longer, will not shrink (which is very important), and will retain the original appearance and will not crack over time. The next stage of processing is the creation of a house kit according to the project; at this stage, the dried timber is processed on German four-sided machines (a profile is cut out, grinding is performed). This house kit according to the project can be easily assembled by 2 people.

The wall thickness can be from 190 mm to 340 mm, of which mini-beams are 45 to 70 mm thick on the outer and inner sides, and between them there is ecowool insulation from 100 to 200 mm.

The minimum house kit consists of external walls And internal partitions, its cost is calculated strictly in proportion to the number of cubic meters. wood

Turnkey wooden house inexpensively

The preference of a huge number of developers is focused, first of all, on wooden house was warm and reliable. To achieve such goals, there is a beneficial and efficient technology construction of wooden houses "Double timber". Time-tested Finnish way buildings has firmly established itself in the construction market, this technology has big amount advantages.

Double beam is unique system, consisting of two elements, which uses lumber that has gone through many stages of drying and calibration. Wall elements are divided into external and inside, between which there is space for filling with ecowool insulation. The special structure of the locking connectors allows you to create a tight seal at the joints without the use of metal fasteners or adhesive compositions, which is very important when building environmentally friendly and durable housing.

The beginning of all work is the preparation of timber for future construction. Lumber passes chamber drying to prevent the appearance of cracks during operation. After preparation, the material goes into production. Using modern four-sided machines, all structural elements are created that fit together as accurately and without gaps as possible.


When designing each house, the time for its construction is determined. In some cases, there is a need to carry out work in winter time. Thanks to the double beam technology, this problem can be easily solved, since during construction this technology does not use cement mixtures or other processes that are not resistant to sub-zero temperatures. Regardless of what time of year the construction is carried out, a structure built using double-timber technology will not be subject to shrinkage thanks to calibrated, dry lumber.

An undeniable advantage is the cost-effectiveness of the entire structure. When compared with other construction methods, savings start from the foundation. Lightweight design at home will allow the use of a screw foundation, which will significantly affect costs. Despite the light weight of the house, its structure will have high rigidity thanks to the double locking connection of the longitudinal profiles.

A proper wooden house should have excellent heat-saving properties. The wall built using Finnish technology will have triple protection. This protection consists of an outer beam, a middle with a heat insulator and internal beam. Boards tightly adjacent to each other will provide effective wind protection and, together, will keep you warm in winter and cool in summer. The triple insulation system will eliminate the appearance of condensation, and thanks to unique properties wood, the humidity inside will be moderate. Dry wooden walls will create their own microclimate, filling the entire room with the aroma of wood.

One of the main advantages of the Double Beam technology is savings. Let's take a closer look. So you're done right choice, deciding to move to live outside the city. The first thing you feel

You can save your money (by choosing the Double Beam construction technology) by installing the foundation. The construction of the house is quite light, which protects you from extra costs for the construction of expensive, powerful foundations.

1) You order the entire range of works from the Novproekt company. Construction itself using double timber technology is very inexpensive. Accordingly, you again save your savings.

2) The most inexpensive option construction of your country house- Buy a ready-made house kit for self-installation. This is where our products have no equal! Neither in cost nor in ease of assembly!

And this is actually true! Two men without any house-building skills can easily assemble a house with an area of ​​100 m2. But this is about the box itself at home, but on roofing(sheathing with metal tiles or something else) you will have to invite specialists, i.e. We need, as they say, a full hand here. Thus, your savings when building your home will amount to a decent amount!

Speaking again about cost savings thanks to double timber technology, it is worth noting that a house built from timber does not require multiple finishing works, fiddling with dry mixtures, decorative plasters. Facade finishing It will only cost you regular painting with varnish. A beautiful and aesthetic appearance will not require constant repair of cracks or frequent renewal of façade painting. Natural environmentally pure material will be able to withstand many weather conditions. Interior also does not require any additional finishing. Smooth wooden walls already have a finished decorative look.

An inexpensive house made of timber will always create a pleasant atmosphere of coziness and comfort. Modern technology turnkey double timber deserves the title optimal solution for construction. The issue of cost-effective construction of a house, thanks to such a system, can now be easily resolved. Construction wooden house will take a short amount of time, and after completion final finishing You can immediately live in the house without having to wait for the structure to shrink.


STEPS OF CONSTRUCTION OF A HOUSE FROM DOUBLE BEAM:

Sketch design at this stage we must decide on the choice of architecture, plans, facades of your future home. To do this, you simply voice your wishes to us or send us a picture of the project that you would like to build. You can also choose one of our standard projects from the house catalog.

Detailed design At this stage, our designers draw a diagram for cutting off products for production. The working design is done free of charge if a construction contract is concluded. If you are not ready to build yet, a detailed design will cost you 200 rubles per sq. m. total area of ​​the house along the axes.

Making a house kit is the most important and labor-intensive process. As a rule, the production of products for the construction of a house with an area of ​​130 - 150 m² takes an average of 1 month. Depending on the complexity of the architecture of the future house.

Installation on site is carried out after the production of the “constructor” for assembly. It is important to note that the installation of a house made of double timber is carried out without single nail or the use of adhesives that are harmful to health. The strength of the structure is achieved thanks to strong locking connections.


Wood, as a material for construction, is, first of all, environmentally friendly. This material can be considered almost ideal in terms of easy processing and affordable prices. A huge number of different variations in design have allowed us to create a new understanding in the construction of houses from timber. Many designers and architects prefer the “double beam” technology for building houses. Warm and comfortable home will last long years to you and subsequent generations.
