Houses made of double timber are rotting. Turnkey wooden house inexpensively. No problems of traditional wooden log houses
















Initially, Finnish houses in Europe were called buildings made of laminated veneer lumber - high-budget designer houses with shortened construction times. The harsh climate (25% of the country's territory lies beyond the Arctic Circle) and rising energy prices year after year prompted Finnish engineers to develop a new, less costly technology.

The first houses made of double timber appeared in Finland more than 40 years ago and immediately became the object of close attention from neighbors. Everyone was interested in questions about the features of the technology, energy efficiency of buildings and minimal capital investment. Since then, the name of the houses has become a household name; they are built not only in Russia, but also in Norway, Estonia, the Czech Republic, Austria, Germany and the UK.

Beauty, comfort and savings come from Europe

The essence of technology

The name of the technology refers to the method of forming walls, which serves as an alternative to classic wooden houses. The wall is a structure of two wooden elements (planes) with a gap filled with insulation. Features of the technology are the following components:

    Wall material. Profiled timber that has undergone thorough drying in vacuum chambers.

    Insulation. Non-flammable and environmentally friendly fiber is used, often mineral wool.

    Sealed connection wall structures using the tongue-and-groove locking method, providing the necessary structural rigidity.

The technology is a successful combination of the best qualities of log, timber and frame buildings:

    Natural materials and eco-friendly life, like in a log house;

    Geometric accuracy parts and ease of assembly, as in timber;

    Warmth and significant savings energy resources, as in frame.

The assembly process is exactly like a designer's

Advantages and disadvantages of technology

Houses built using double timber technology are distinguished by high aesthetics. The details preserve the natural texture of wood, which makes this building attractive to fans of eco-style, and its walls a highlight of the interior. Professional builders note several more advantages, thanks to which such houses are in constant demand:

    Quality. Factory-made parts made according to drawings are used, which do not require additional fasteners.

    Reliability. The strength of the structure is ensured by a rigid connection based on the log house principle, a tongue-and-groove system.

    Economical. Compared to other technologies, you can save up to 30% of your budget without shelling out money for finishing.

    Build speed. Ready-made parts with precisely adjusted dimensions allow you to build a house at high speed (from the prepared material, installation of a house with an area of ​​up to 100 m2 takes 6-8 days).

    All-season. Installation can be carried out at any time of the year, since there is no “wet” work.

    Safety. Wooden surfaces are treated with a fire retardant, which retards the spread of flame, and non-flammable materials are used for insulation.

    Thermal efficiency. The three-layer construction of the walls saves heat well (the efficiency of a wall made of double timber with parameters 44x150x44, a wall made of laminated veneer lumber with a thickness of 250 mm and a wall made of rounded logs with a diameter of 270 mm are the same).

    Vapor permeability. A cottage made of double timber maintains a favorable microclimate by regulating the level of humidity in the premises.

    Environmental friendliness. Structural elements are made from natural solid wood (pine, aspen and maple, less commonly larch, oak and cedar), without the use of technical glue.

Housing made from double timber maintains a favorable microclimate

Like any object of the real (and therefore imperfect) world, houses made of double timber also have their drawbacks:

    Risk of insulation shrinkage. Possible with poor-quality installation using slab mineral wool. When using ecowool (bulk insulation), this possibility is reduced to a minimum.

    Cracks. They occur if unevenly or incompletely dried wood was used in the manufacture of the house kit.

    Risk of uneven shrinkage of the wooden structure. Uneven shrinkage (with deformation of the wall surface and the appearance of cracks) is possible in a newly built house during severe frost. A preventive measure is the use of quality materials.

    Difficulty of repair. You can replace a structural part (damaged crown) using jacks, which is very problematic. Communications are laid through castle cuts and hidden under the casing. If it is necessary to replace them, only the covering materials are removed.

Ecowool - a modern way to insulate a home

On our website you can get acquainted with the most popular projects of houses made of double timber from construction companies presented at the exhibition of houses “Low-Rise Country”.

Question about the need for vapor barrier

The walls of a house built using double timber technology are vapor permeable, that is, they are able to absorb excess water vapor from the air and return it back, restoring the natural humidity in the room.

The technology does not provide for the use of vapor barrier film in the walls. Placed between layers of timber, it will not extend the life of the house, but will disrupt the natural circulation of air and lead to the formation of condensation. Depending on where it is located (before or after the insulation layer), moisture will collect on the wooden surface or be absorbed by the insulation. Both will lead to damage and destruction of the wall. The only place where it is recommended to install a vapor barrier is on the floors.

What are the savings of using double timber technology?

The tight-fisted Finns did their best, creating a technology that allows you to save money both during the construction of a house and during its subsequent operation. You can feel its advantages by learning about some features:

    In the construction budget no expense item for insulation.

    Due to the lightness of building structures (the weight of a house kit of 100 m2 is approximately 20 tons, the weight of ordinary timber is 2 times more) you can save on the foundation. In most cases, the strip foundation is replaced with a shallow strip or pile foundation.

Foundation organization diagram

    No need to allocate funds for special equipment.

    Finishing can begin without waiting for shrinkage(it is minimal, 5-6 times less than the shrinkage of a timber house and rarely reaches 1 mm).

    No need to waste money and time on caulking walls.

    Walls produced using high-precision equipment no need for leveling or sanding.

    You can move into the house immediately after installation is completed.(the timber will stand for 1 year).

    You will not overpay for heating your home; You can limit yourself to an economical heating system. Thermal insulation of walls made of double timber with a thickness of 190-220 mm corresponds to the thermal insulation of a wall made of profiled timber with a thickness of 440 mm (made of brick or foam concrete - 1000 mm).

The house made of double timber is warm in any weather

On our website you can find contacts of construction companies that offer the service of building houses from double timber. You can communicate directly with representatives by visiting the “Low-Rise Country” exhibition of houses.

Features of construction technology

Although a house made of double timber is built in a week (you can watch it grow before your eyes), the overall construction cycle (with an area of ​​up to 100 m2) takes about 2.5-3 months, which is also not bad. You need to understand that in this case some “pitfalls” may appear:

    Preparation of the material may take from 2 to 4 weeks. This includes drying and cutting the material, and the duration of the process depends to a large extent on the initial moisture content of the wood. It is not recommended to shorten the drying time; this will increase the likelihood of wall deformation.

    Many companies do not sell double beam house kits without installation. Self-assembly is, without a doubt, a fascinating and valuable experience, but, as you know, it is also “the son of difficult mistakes.” Qualified workers will save you from making your own mistakes, save money and, what’s nice, will spend the minimum possible time on it.

The critical stage is preparing the house kit

    There are different insulation options. They use ecowool (processed natural material), mineral wool (artificial insulation containing glue) and synthetic polymers - polyurethane foam or polystyrene foam chips. In any case, it is important to calculate the required amount of insulation; its deficiency will make the walls cold. Experts do not recommend using sawdust because of its high hygroscopicity and attractiveness to mice.

    The tree needs additional processing antiseptic and fire retardant. Some manufacturers do it themselves, during the preparation of the house kit, others supply a clean board with a natural texture. In the latter case, you will have to take care of protecting the walls yourself.

Final touches: finishing a house made of double timber

Another advantage of the double timber technology is that it is not necessarily finished. The wooden surface is attractive in itself and will fit into any interior. In any case, when deciding on finishing there are two ways:

    Do not use finishing materials at all(especially if the scrap parts were processed by the manufacturer).

    If desired, you can change the shade of the wood according to the standard recipe: the surface is primed, painted or just tinted, and then covered with a protective varnish. In this case, it is recommended to choose natural, close to natural, shades of the color palette.

Wall tinting completed

If you decide to use decorative impregnations, choose formulations from trusted companies. The famous environmental friendliness of a house made of double timber can easily be negated if you use uncertified products from unscrupulous manufacturers. Such varnishes and dyes are often toxic and cause allergies.

Minimum cost of turnkey double timber housing

It is impossible to answer unequivocally how much a double timber project costs, because there is no single, standard form of house kit on the market. The price per 1 m2 depends on the set of elements offered by the construction company. You can choose from several assembly options:

    Kit for partially self-assembly(if there is a foundation on the site). It has a minimal cost and includes ready-made numbered elements manufactured according to assembly drawings. They will build load-bearing walls, internal partitions and ceilings, and install a rafter system; and for further work we will have to find other performers. The house can be inexpensive if there are communications on the site. The price starts from 8-9.5 thousand rubles/m2.

A practical option for a small area

    Basic kit. The company carries out some construction and installation work: the zero cycle with the installation of a screw foundation, the construction of load-bearing walls and internal partitions, the installation of plastic windows, the assembly of the roof with the selected roofing material. A house made of double timber, the price of which starts from 15.5-16.5 thousand rubles/m2, is an attractive option for a significant part of buyers.

    Turnkey kit. The basic kit is complemented by external and internal finishing work, and the installation of communications (usually the installation of electrical wiring and heating systems, as well as water supply/sewage systems). The project will cost 16-19 thousand rubles/m2.

House with double light

    Individual project. It will cost more than any standard one, but it will fully correspond to the customer’s ideas about a wonderful home of his own. Such projects are interesting in their details - a terrace, panoramic glazing, a spacious living room with a fireplace, a steam room, a second entrance. A popular solution is a house with double light, when the space between the first and second floors is combined. This solution expands the interior space, filling it with light and freedom unavailable in an ordinary room. Prices start from 25-30 thousand rubles/m2; if materials are ordered in Finland - 3-4 times more expensive.

How to choose the right project

Extreme opinions about the prices of double-timber house designs are equally erroneous. It is wrong to think that such houses are cheaper than apartments; Those who think that nothing worthwhile cannot be built for less than 4-5 million are completely wrong. A country house can be comfortable and profitable in any segment, from economy to premium; The main thing is that the project is well thought out and the materials are of high quality. The choice may be equally influenced by the following factors:

    Financial opportunities. It is assumed that, before entering the office of a construction company, the customer has decided on the budget he is willing to allocate for construction. Specialists in the field can be of great help. Having many years of experience, they will help you navigate the technological intricacies and make the best choice.

    Features of the land plot. They can affect the final cost of the project. The architect will definitely take an interest in the location and topography of the site, the presence of access roads and the possibility of connecting to a centralized gas and water supply.

Classic building with a mini-terrace at the entrance

    Customer requirements. Whatever they are, the architect can help correct them and thereby avoid strategic mistakes. Thus, a one-story house with a spacious terrace or veranda on a small plot will narrow the possibilities for landscaping the territory; It is better to choose a two-story project. It is also important to decide on the style of the future cottage. Despite some limited possibilities, wooden house projects are carried out in a variety of architectural styles. Only a few people like eco-style, chalets or rustic. Much more often, customers pay attention to projects made in a modern style with Scandinavian or minimalist elements.

    Cottage functionality. It is necessary to determine not only the area necessary for comfortable living of the family, but also additional parameters. The customer must understand whether he needs a garage, a large hall, storage rooms and a study; how many bedrooms and bathrooms will be needed. For a large house, it may be necessary to allocate space for a kitchen-dining room, home theater, gym, sauna and relaxation room. In luxury buildings, at the request of the customer, there is a spa complex with a swimming pool and sauna, a wine library, a spacious terrace with panoramic glazing, and a billiard room.

Projects and prices of houses made of double timber

A wooden country house made of double timber, built in compliance with technology, will be reliable and comfortable regardless of the price category. Construction organizations that care about their reputation approach any project equally responsibly. Customers are offered standard lines of houses with a thoughtful layout, which are customized individually.

Double timber houses, with designs and prices spread over a wide range, are increasingly looking like a smart investment. In the Moscow region, prices for such projects are presented as follows:

    Houses with area up to 100 m2: 900 - 1,300 thousand rubles.

    Area from 100 to 200 m2: 1,300 - 2,200 thousand rubles.

    From 200 to 300 m2: 2,400 - 3,500 thousand rubles.

Conclusion

Private houses made of double timber, a novelty for many Russian homeowners, have been built in Europe for decades; this can serve as indirect evidence of the reliability of the technology. When choosing a construction method, it is important to correctly set your personal priorities in order to understand what result you want to get. And, perhaps, a house in whose walls expensive wood is replaced by effective and durable insulation will seem worthy of your attention.

Building houses from wood has many advantages, but it is also not without its disadvantages. Houses made of wood are poorly prepared for finishing. When working with wood, the natural humidity of wooden houses causes significant shrinkage and cracks. To avoid these shortcomings, specialists from different countries are inventing new technologies. One of these new products is the construction of a house from double timber. The technology came to us from the Scandinavian countries. The climate there is very similar to Russia, so this technology has taken root well here and is actively practiced by Russian developers. Like many other Finnish technologies, the construction of buildings based on double timber does not require special equipment or tools. Therefore, it is possible to build a house using this technology with your own hands.

In fact, the construction technology using the “double timber” system has little in common with timber construction in our usual understanding. This technology is often also called mini-timber construction. This is due to the fact that the wall structure of such a house consists of two specially profiled boards with a cross-section of 47x145 or 45x135 mm with a gap between them of at least 10 cm, which is filled with insulation.

This technology is similar to the method of frame house construction, the only difference is that for such a house there is no need to install a frame to build walls.

Advantages of houses made of double timber

Houses made of double timber are not without the main advantages of any wooden house: environmentally friendly design, natural breathing of the walls, favorable microclimate and presentable appearance with beautiful wood texture.

In addition, there are many advantages that, for example, a chopped and rounded log house or a house made of profiled timber cannot boast of.

  • To create the blank, only chamber-dried lumber is used, which will avoid shrinkage and cracks of the finished walls. The shrinkage of the finished house is no more than 1 cm per 1 m of wall. You can even ignore such indicators and proceed immediately to installing windows and doors and interior decoration.
  • Wall kits are often supplied after being treated with an antiseptic. There is no need for additional protection of the walls from mold; only finishing impregnation with tinting or covering compounds is required.
  • High energy efficiency. Such buildings do not require additional insulation other than that laid between the walls.
  • No additional compaction is required between individual mini-beams along the height of the wall. A tight connection is ensured by a special profile of the boards due to a double lock.
  • The insignificant weight of the wall elements allows assembly without the use of special equipment. Even one person can assemble walls from double timber in 3-5 days, depending on the size of the house.
  • High pace of construction.
  • Cheapness of a finished house.
  • Possibility of hidden installation of all communications in the thickness of the walls or under the floors.
  • Good heat and sound insulation.

Undoubtedly, houses made of double timber also have some disadvantages. Like any wooden structure, they have a high fire hazard and require constant maintenance of the facade (it is necessary to use reliable impregnations to protect against precipitation and ultraviolet radiation). Each construction technology is not without its drawbacks, so the choice is yours. One has only to say that construction from double timber is gaining momentum in Russia, along with frame housing construction.

Technology of building a house from double timber

If you have studied all the pros and cons, and your choice has fallen on a house made of double timber, then you should familiarize yourself with the construction technology step by step.

Design work and procurement of materials

Any construction must begin with the development of a detailed house plan and utilities. Perhaps the problem in building such a house may be the purchase of the necessary material. This technology is new for Russian builders, and there are not many manufacturers of high-quality mini-beams on the market. It is likely that you will not be able to find a suitable company in your region. Don’t stop there, logistics are now well developed, and you can deliver the material to your site without compromising the quality of the material and construction time. Each manufacturer has a set of standard designs that you can rework as you wish at minimal cost.

Site preparation and foundation installation

Houses made of double timber are lightweight, which allows the use of columnar or pile foundations. It is much less common to install a shallow strip foundation (if the height of the house exceeds 2 floors) or a slab foundation (floating soils that behave unpredictably in the off-season). The construction of a foundation for a house made of double timber is no different from the construction for a frame house. We will see more than once analogies between the construction of frame houses and buildings based on double timber. Both technologies came to us from Finland and have many similar features.

Installation of the bottom frame and floor beams

Here we can also take the floor preparation steps from frame technology. After checking the horizontalness of the foundation, waterproofing is laid on it. Beams of the lower frame are laid on top of it, which are usually made of timber 100x200 or 100x250 mm, depending on the planned thickness of the wall. Installation of the first floor floor joists can be done on top of the frame or at the level of the frame using special fasteners - beam supports. The pitch between the lags is calculated based on the selected insulation and the expected load.

Usually, the floors are insulated immediately and a rough floor covering or even a finishing floor is laid. Step-by-step instructions for arranging the floors of the first floor after installing the logs:

  • Fastening the cranial beam to the side surface of the log.
  • Subfloor flooring.
  • Vapor barrier flooring.
  • Floor insulation. Typically, mineral wool or ecowool is used for insulation.
  • Rolling out another layer of vapor barrier.
  • Laying rough flooring (OSB, chipboard, plywood) or finishing (floor board, parquet board).

If you are at least a little familiar with building a house using frame technology, then this will not be a difficult test for you. The main thing is to follow the technology and lay the insulation tightly without voids. The films will protect the insulation from moisture from the ground or future rooms.

Walling

The main features of building a house from double timber lie in the installation of walls. Here you will have to rely on your own hands, because even the skills in building houses from profiled timber or frame buildings will not give you any advantages.

Let's understand the stages of wall construction

Installation of the first row

The first row of timber is usually represented by boards, where only the tenon is milled, since the lower part of the timber is laid on the frame. First, we make markings and pre-install the full contour of the first row. To control the correct gap between the outer and inner walls, temporary cuts are hammered in every 2 meters. After checking the geometry and level of the first row, both walls are fixed to the frame using corners and capercaillie (screw with a hex head). After this, the temporary cuts are removed and only those included in the technological map of the house are left. They are located on walls longer than 3 meters to maintain verticality and maintain the planned gap between the walls.

Laying the second and subsequent rows

Each subsequent row is laid on top of the previous one on an existing single or double tenon. The mini-beam is hammered tightly using a sledgehammer through a wooden spacer. It is important to follow the rule: in the corners of the house, the chamfer of each row should be exactly in the middle of the subsequent row of the perpendicular wall. If this rule is violated, it means that one of the rows is poorly punched or the production technology of the workpiece is broken. In case of insufficient penetration, the walls are finished off or screeded at the ends. If the technology is violated, the wall is dismantled down to the defective row and they try to leave it until the last row of installation.

The walls of the house are also screeded in a horizontal plane. This is necessary if there are composite walls in the structure, that is, when one wall is made of two or more boards along its length. The screed is not removed from the row until the next one is laid, then the screed is moved to the row above.

Laying the last row

After the last row is erected, a so-called cap is usually laid. Between the two mini-beams there is a board or a full-fledged profiled beam, which covers the insulation and serves as a platform for attaching the top trim of the ceiling beams.

We have already said that technology does not require special equipment or a large number of people. However, when assembling the walls of a house from double timber, great care and painstakingness are required.

Wall insulation

As with frame structures, this is the most important stage for creating a warm home. Incorrect insulation technology can ruin all your efforts.

  • Ecowool insulation. Ecowool is a bulk material based on recycled cellulose. It contains all the properties of wood, so the wall will have excellent vapor permeability and the necessary air exchange will be maintained in the house. Ecowool is blown into the gaps between the outer and inner walls. There is no need to use a vapor barrier, because the material is not afraid of moisture. The height of the well from the walls should not exceed 3 meters; after insulating the insulation, it must be allowed to settle and the required amount is added. Initially, the double beam technology was envisaged only using ecowool as insulation, but mineral wool was also used on the Russian market.
  • Mineral wool. The material is afraid of moisture, so a layer of vapor-permeable membrane is laid on the outer wall side, and a vapor barrier is laid on the inner wall side. Insulation is laid into the walls during their construction. In this case, installation is slightly delayed, and the material requires dry weather throughout the entire time of work on the walls.
  • Expanded clay, sawdust, and expanded polystyrene in the form of bulk material can also be used as insulation, but this is rather a deviation from the rules than an option that should be carefully considered. It is not advisable to order a high-quality wall kit made of double timber and save on insulation in the context of Finnish technology. Especially when you consider the low cost of such structures, made in compliance with insulation technology.

Ceiling and roof

Installation and insulation of the ceiling is no different from similar work in frame structures. The only exception is that often manufacturers of double beams supply house kits with assembled trusses for ease of installation of the roofing system. The materials for the roof and finishing of the ceiling are identical to the frames.

Communications and finishing

The double beam technology allows you to begin finishing immediately after assembling the frame of the house, because such walls do not shrink. Most communications are also laid in the process of working with floors and erecting walls, because most of these elements are “hidden” inside the walls and interfloor ceilings.

Conclusion

Starting to build a house using the “double beam” technology with your own hands is a rather risky undertaking. Construction just seems simple. Violation of the wall construction technology can disrupt the comfort in your home or even reduce the rigidity of the structure, because there are no additional fasteners inside the walls. The entire structure maintains its shape due to the correct bowls and cuts. Lack of care in sealing the beams together will create cracks in the future. Violation of the level between the outer and inner rows can lead to difficulties in installing doors and windows, and sometimes breaks the sealing of the walls. It is worth assessing your carpentry skills before starting to build such a complex high-tech project. It would be a good idea to read the recommendations and reviews of those people who have decided to take this step.










Gone are the days when houses were built only from logs. Wood was the only available material that no one thought about processing. The rotten bathhouse was easy to reassemble, since there were enough trees around.

Today, not every budget can handle a house made of logs or timber, and not everyone wants to wait for the final shrinkage, which can take 2 years. But thanks to modern technologies, natural materials are used sparingly, and housing is built quickly and has improved characteristics. One of these technologically advanced methods is the construction of houses from double timber.


House built using double timber technology

Construction from double timber: competitiveness of Finnish technology

The double timber construction technology was invented by the Finns and was originally intended for use in regions with harsh winter conditions. This method is suitable not only for building a house, it is applicable for a bathhouse or veranda.

Comparison of prices for materials used in different technologies (compared to double timber):

    Double timber with insulation (thickness 150 mm) - 5500 RUR/m².

    Profiled timber (thickness 150 mm) - 3500 RUR/m².

    Rounded timber - from 5 thousand rubles/m².

    Frame-panel technology - from 3.5 thousand rubles/m².

A comparison shows that the double beam technology is more expensive than others, but the price of insulation is already included in it. Insulating the remaining options will level out prices.

Reasons for the insufficient distribution of houses made of double timber in Russia

The above comparison clearly shows one of the reasons - the customer allocates a certain budget for construction, which he is not ready to exceed.

A house project made from double timber can have a complex layout and an original façade. The production of some parts (joints, profiles) is only possible on high-precision computer-controlled woodworking machines. Without specialized equipment, the company will not undertake the work.

About the Finnish technology for producing double timber

Double timber using the Finnish “warm house” technology should be distinguished from its profiled counterpart. If profiled timber is made from single-layer solid wood, then double-layered timber is a structure of two wall elements (boards) connected into a tenon using a special profile. The technological gap formed between them is filled with insulation with heat, steam and sound insulation properties. This layering prevents condensation from forming and retains heat.

Spruce and pine wood is used to make boards, as it is light, inexpensive and easy to process. Before use, the workpieces are dried in convection chambers. This procedure increases the strength of the wood and protects it from rotting. Lumber has high consumer characteristics: it becomes lighter and stronger, and is not subject to cracking or deformation.

The prepared boards are processed on machines, acquiring the shape and profile specified by the project, as well as a smooth surface. Tenons and grooves are cut into the products, fastening the timber using a tongue-and-groove system. In such a system, inter-crown insulation, necessary for log cabins or timber buildings, is not needed. For a house kit made of double timber, corner joints (bowls) are also made to prevent freezing of the corners and through blowing.

Insulation

Ecowool (backfill option) or mineral wool are used as insulating material, and the first is preferable for a number of reasons:

    Appearance. Lightweight grayish material with a fibrous structure and good insulating properties (heat retention).

    Compound. The basis (about 80%) is cellulose (waste paper). Additional components are boric acid and borax, which give the cotton wool antiseptic and non-flammable properties.

    Properties. Allows air to circulate without retaining moisture (the house does not need a vapor barrier, which cannot be said when using mineral wool). Protects wood from rotting. Sound insulation is 1.5-2 times higher than that of mineral wool.

Thermal insulation characteristics are similar for walls:

    made of double timber, 190–200 mm thick;

    log, 400 mm;

    foam concrete, 880 mm;

    brick, 900-1000 mm.


Only qualified builders who have undergone special training are involved in the installation of walls.

On our website you can get acquainted with the most popular projects of houses made of double timber from construction companies presented at the exhibition of houses “Low-Rise Country”.

Advantages and disadvantages of double beam technology

The benefit of choosing a house made from double timber is determined by the advantages of the technology:

    Factory quality. Modern equipment ensures high precision of parts, which is unattainable in artisanal conditions.

    Deadlines. Wall kits are produced within 2 weeks. Assembly of walls, depending on the type of project, takes 10-15 days.

    Savings during construction and operation. The construction of houses from double timber will cost 30% less than similar housing made from glued profiled timber (200 mm thick). Energy saving is 2 times more effective.

    Construction. It is carried out year-round. No special equipment is needed to build the frame.

    Saving on foundation. Due to the lightness of the structure, a pile-screw foundation can be used, which is cheaper than a strip equivalent or a monolithic slab.

    Wall properties. High heat, steam and sound protection characteristics. The front surface does not require finishing; it is treated with impregnation and, if desired, painted in the color you like.

    Interior work. Engineering communications are located in the wall. Sealed seams (lock joints) do not require additional caulking. The sanded surface of the walls is ready for varnishing or painting.


Aesthetics of natural wood; interior work is coming to an end

    Shrinkage. Thanks to the use of chamber-drying material, shrinkage does not exceed 2-3%. You can move in without spending a year waiting for settlement (for example, compared to a log house).

    Eco-friendly and stylish. Natural wood is used, without adhesives or impregnations.

The “double beam” construction technology also has its disadvantages:

    Requirements for the quality of the material. The manufacture of wall elements requires special equipment and personnel skills. Poorly dried material can cause uneven shrinkage, cracking and noticeable distortion of the walls.

    Possible shrinkage of insulation. This can happen if technology is violated or low-quality insulation is used.

    Difficulty of repair. If there is a need to replace one of the boards, it will be almost impossible to do this without the involvement of specialists.

Double timber house: from design to implementation

No matter how simple the “double beam” technology may seem, it is logical to entrust house projects and their installation to an organization that has completed projects (which will be confirmed by a portfolio). The customer can count on:

    Typical project. This option will reduce construction costs, as it is usually adapted to local conditions; It is permissible to make minor changes to it.

    Project to order (individual). It is an order of magnitude higher, as it may include geotechnical surveys, complex technical solutions and elements (for example, a roof of complex shape or a veranda).


Individual project with veranda

In addition to project development, the construction company’s package of services includes preparation of a sketch, documents and estimates, production of a set of parts, and assembly of the structure. The house is installed according to the standard wooden house assembly scheme:

    The foundation is being constructed and waterproofed.

    The embedded crown (the bottom layer in contact with the foundation) is mounted and leveled.

    The walls are erected, then the roof.

    Utilities are being installed.

    Final (interior) finishing is being carried out.

    All work is guaranteed.

The strength of the structure is ensured by the method of laying wall beams and floor beams (they are cut into the walls). Another secret is absolutely dry lumber, which retains 11-15% moisture content after drying.

The advantages of a turnkey double timber house are visible to the naked eye. After the project is approved and the contract is signed, the customer can only enjoy the process without bothering himself with purchasing materials, searching for builders and observing their work. Specialists will take care of everything.

Companies offer houses made of double timber, the designs and prices of which can be changed. You can reduce future expenses by choosing cheaper mineral wool instead of ecowool. The thickness of the walls is also chosen by customers.

The market offers houses made of double timber of various sizes and for any budget. For comparison, it is convenient to divide them into categories depending on the area (Moscow region):

    Up to 100 m². The price of a house kit starts from 335-500 thousand rubles.

    From 100 to 200 m². From 680-900 thousand rubles.

    From 200 m². Starting from 1.2-1.8 million rubles.

What can be built from double timber

Not only houses are built using double timber technology. In this way you can decorate your garden plot by building:

    gazebo and canopy;

    garden, guest and children's houses;

    utility room (tool house).

Since the wall elements have a high-quality processed front surface, they do not require additional finishing and give the buildings an impeccable eco-friendly style.

Experience shows that there are moments in the construction of a house where it is absolutely not worth saving, but there are nuances where you can not only save, but rationally spend the budget (which is a kind of reasonable saving).

A little about the bathhouse: a look from different sides

Building a bathhouse is not the cheapest pleasure, since a durable result requires high-quality materials and special construction methods. Double beam technology can speed up the process while ensuring the desired result.

The walls of the bathhouse are constantly exposed to high temperature and humidity and inevitably absorb moisture. In an effort to protect the structure, some owners insist on using a windproof membrane in the wall, between the insulation and the internal element of the double beam. The purpose of such a vapor barrier is to prevent steam from entering the insulation from the interior. If protection is not installed, wet insulation prevents air from circulating, stops saving heat and triggers the destruction of wood.

Construction companies insist that the structure provides sufficient vapor exchange, and the additional layer disrupts the “breathing” properties of wood. When using a waterproofing layer, steam will condense on it; the insulation will remain dry, and the log will begin to rot. According to the technology, it is enough to use the film in ceilings.

Conclusion

The double beam technology, developed and tested by Finnish builders, is confidently gaining popularity among Russian customers. Most are attracted by the possibility of quick construction without loss of quality, so valuable in the conditions of a short summer season and frosty winters. Improper installation can destroy the most resistant wood. To ensure that a house made of double timber does not become a disappointment and you do not have to pay for modifications, the optimal solution may be to order a turnkey house.

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

The wood used goes through several stages of processing: First, the wood is sawn on a high-precision circular sawmill, which provides it with ideal geometry. Then the entire timber with a humidity of 40-60% is placed 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), will retain its 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 the fact that a wooden house is warm and reliable. To achieve such goals, there is a profitable and effective technology for constructing wooden houses “Double Beam”. The time-tested Finnish method of construction has firmly established itself in the construction market; this technology has many advantages.

Double timber is a unique system consisting of two elements, which uses lumber that has gone through many stages of drying and calibration. The wall elements are divided into external and internal sides, between which there is a space for filling with ecowool insulation. The special structure of locking connectors allows you to create tightness in joints without the use of metal fasteners or adhesives, which is very important when building environmentally friendly and durable housing.

The beginning of all work is the preparation of timber for future construction. The lumber undergoes 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. 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. The lightweight construction of the house 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 an inner 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 condensation, and thanks to the unique properties of 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 made the right choice by 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 structure of the house is quite light, which protects you from unnecessary 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 for building your own country house is to buy a ready-made house kit for self-assembly. 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 frame of the house itself, but for roofing work (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 saving money 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, or decorative plasters. The façade finishing will cost only with regular varnish painting. A beautiful and aesthetic appearance will not require constant repair of cracks or frequent renewal of façade painting. The natural, environmentally friendly material can withstand a variety of weather conditions. The 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 of turnkey double timber deserves the title of the optimal solution for construction. The issue of cost-effective construction of a house, thanks to such a system, can now be easily resolved. Construction of a wooden house will take a short amount of time, and after completing the finishing touches, you can immediately live in the house without the need 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 catalog of houses.

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 a 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 timber” technology for building houses. A warm and comfortable house will serve you and subsequent generations for many years.

The technology for assembling wooden houses from double timber was borrowed from the Finns. This method has been used in low-rise construction on the Russian market quite recently. This is the main reason for the great interest of developers. Many people who want to have environmentally friendly housing want to figure out how profitable it is to use such technology in private housing construction. The pros and cons of building materials, construction technology, and operation of houses made of double timber are described in detail in this article.

Anything new is always alarming. This is the case with modern construction technology - the Finnish method of assembling houses, where double timber is used as wall material. What are the pros and cons of the material and the assembly technology itself?

Positive sides

  • Natural wood is environmentally friendly.
  • Elements for internal and external walls are factory-made from dry sanded boards 45 mm thick and are 100% ready for assembly. After drying, the boards reach a humidity of no more than 12%, which contributes to minimal shrinkage of the house. Therefore, you don’t have to wait six months to move in and celebrate your housewarming.
  • Each tongue and groove beam is equipped with a double comb lock, which creates a tight, reliable, windproof connection. Therefore, sealing of seams is not required, as in log buildings.

High strength of double timber connection

  • With a small wall thickness of 220 mm, where the wood is 90 mm and the insulation is 130 mm, high energy saving rates are ensured.
  • The total weight of the building is relatively small, which makes it possible not to lay a capital foundation. On loose and unstable soils on the site, screw piles are the ideal foundation. But, if the nature of the soil allows, then one of the options may well be a shallow strip foundation.
  • With the use of modern technology in wooden housing construction, it has become possible to speed up construction times as much as possible.
  • Simple assembly of wooden elements is carried out without the use of special equipment. The work is performed by several workers, which significantly saves construction costs.

Important! You can build houses from double timber at any time of the year, the only requirement is the absence of rain or snow.

Disadvantages of double timber

  • The main disadvantage of the technology is the uneven shrinkage of the wooden structure, which occurs as a result of a large difference in temperature from the outside and inside the building. The difference should not be more than 2-3 mm.
  • It is difficult to achieve high quality assembly, so it is necessary to enter into an agreement with professionals, and not “schemers” who want to make money on what seems to be an easy job.
  • Another important disadvantage is the selection of insulation, which is used to fill the voids between the outer and inner rows. Due to the large range of insulating materials available on the construction market, it is difficult to make the right choice and give preference to any one option. Only experts know what characteristics and properties each type of insulation has.

Despite the fact that the listed disadvantages of double timber are much smaller than the advantages, the main indicator is the operational characteristics of the building. The shortcomings of such technology may appear over several years. The most unfavorable moment is the climatic conditions, so before deciding to build, you should consult with specialists and find out in advance what disadvantages the Finnish construction technology has in a particular region of Russia.

Important! To avoid unpleasant moments associated with shrinkage of the building, you should carefully select candidates for the work and order building material from a trusted manufacturer who guarantees high-quality drying of the timber.

What are the pros and cons of double timber houses?

Assembling a wooden house using double beam technology resembles a “layer cake” - a sandwich, and this design has a number of undeniable advantages.

Positive sides

  • Beautiful and neat appearance.
  • There are excellent thermal insulation characteristics and high energy efficiency of the entire structure.
  • A tight connection and the absence of gaps between the seams creates reliable sealing of the walls and protection from wind penetration.
  • The walls of the house “breathe”, so there is a favorable microclimate in the rooms.
  • The presence of space between the outer and inner rows of timber walls allows you to hide all engineering and communication networks (water supply pipes, sewerage pipes, ventilation ducts).
  • Cost-effective housing due to inexpensive materials, no need for interior wall finishing and additional insulation. Quick payback due to low costs of hiring workers, heating, and building maintenance.

Important! Buildings made from double timber are much cheaper than houses of the same size, but only made from 150x150 laminated timber and without thermal insulation materials.

Disadvantages of houses made of double timber

  • The main concerns are climatic conditions. Therefore, you need to know how the climate of the region can negatively affect a house made of double timber. What are the disadvantages of frequent freezing-thawing cycles? Sudden changes in temperature can cause uneven shrinkage, causing cracks to form in the wood. The use of high quality material reduces this risk.
  • The second significant disadvantage is the wrong choice of insulation. The best choice is ecowool, which is placed between the external and internal walls without tamping, and its blowing is carried out in several stages. Only in this way can the natural density of the insulation be achieved. The main requirement for performing such a procedure is to correctly calculate the amount of ecowool at above-zero temperatures. Insufficient filling of the gaps will lead to the absence of the necessary parameters and a decrease in the energy efficiency of the building, and excess will lead to deformation of the walls at low temperatures.
  • In houses made of double timber, the disadvantage is the difficult implementation of repair work. But the manufacturer guarantees that with timely and high-quality treatment of wood with special antibacterial agents, such a procedure will not be required in the near future.

How can the advantages and disadvantages affect the choice of a house made of double timber?

Having considered all the positive and negative aspects, you can decide for yourself whether to build a house from double timber or not. The pros and cons of such construction were shared almost equally. If the number of the former is much greater, then the disadvantages prevail in importance. Therefore, before you decide to build a house from double timber, all the pros and cons need to be carefully studied and written down in a column. Possible nuances should be discussed with specialists. You should only seek help from professionals with sufficient experience.

Conclusion

In conclusion, we can say that today the construction of houses from double timber is gaining popularity, and every building material and construction technology has disadvantages. Therefore, you need to initially develop an action plan and strictly follow it, the main thing is to take into account all the disadvantages that are present in houses built using Finnish technology.
