Finnish laminated veneer lumber is a new generation building material. Three-lamella Finnish timber Laminated timber using Finnish technology

On Russian market wooden house construction long time Finnish laminated timber was extremely popular. It is known that laminated veneer lumber began to be produced in Finland about 25 years ago. The technological process for the production of timber was constantly improved: new ones were selected adhesive compositions, methods for orienting timber lamellas, thickness of workpieces, etc. The result was a very high quality material - Finnish laminated veneer lumber. Glued together from sorted and specially selected lamellas, Finnish three-lamella laminated veneer lumber combines environmental friendliness with high strength and durability.

Why is Finnish timber so popular?

1. Specially cut wood is used to produce timber.

This is a cut down the center of a log, capturing or removing the core, resulting in radial cut wood that is least prone to warping. As a rule, thin gauge (small diameter trunks) or the top part of the tree is used.

A special feature of laminated veneer lumber using this type of sawing is the orientation of the outer lamellas when gluing with the core side facing out. This technology avoids significant cracks in outside timber during operation.

2. Thick lumber.

In the production of Finnish timber, thicker lumber is used - 75 mm versus 50 mm for Russian manufacturers. Art Holz purchases thicker lumber from an Austrian company that successfully harvests timber in the Leningrad, Arkhangelsk regions and Karelia.

3. Taking care of your health.

Just like Finnish companies, we were the first in Russia to use laminated veneer lumber in the manufacture of polyurethane glue Purbond, which is harmless to health due to the absence of formaldehyde and other components hazardous to humans.

The Art Holz company can offer you a house made of high-quality Finnish timber, which fully complies with Finnish house-building technologies.

Price for Finnish timber cut for the project

The price of a complete house is made up of the cost of those cut for the project external walls, internal partitions, interfloor ceilings from laminated veneer lumber, Mauerlat and load-bearing roof structures.

Today, quite often, buildings made of laminated timber are called “Finnish”, which is not entirely correct and confuses many clients. To build a log cottage, it is not at all necessary to go to Finland. On this moment It is domestic enterprises that are leaders in the production of this raw material and the construction of cottages from these raw materials.

Finnish houses made of laminated veneer lumber

Structures made of laminated veneer lumber are called Finnish, for the reason that it was Scandinavian specialists who created the technique of gluing timber. Timber has always been considered the best and most energy-efficient material, but owners of wooden cottages have encountered such unpleasant situations as cracks, twisting, and other defects. In the 70s of the last century, specialists invented a technique that allows you to make solid timber from several parts. This method makes timber stronger, more reliable and functional. It was after this that national identity was forever assigned to this raw material. Very quickly the gluing technique became known and popular in many countries. Now domestic enterprises produce glued raw materials according to Finnish technology from timber from the northern forest belt, which has been famous for its high quality.

Finnish laminated veneer lumber is widely popular in our country due to its high reliability, energy efficiency and aesthetic appearance. Companies in any region of the state offer to purchase a house made from this raw material. For example, the company “Priozersky Timber Plant” delivers laminated veneer lumber and logs, as well as ready-made house kits from these raw materials, not only in the North-West region, but throughout the country. This company is also engaged in the construction of turnkey buildings.

The high potential of this company, European technologies used in production and, as a result, the high quality of the resulting materials have made Priozersky Timber Mill a well-known supplier of this material not only in Russia, but also abroad. Well-known Finnish companies, for example, “Honka-Talot”, “Evrohonka”, “Lameco”, use timber from the Priozersky Timber Plant Group to produce laminated veneer lumber.

History of invention

The history of laminated timber begins in the 12th century. It was in those distant times that Japanese archers began to make weapons by gluing together components from bamboo and wood. After this, well-known European architects began to use bent laminated, wedged structures made of timber in the construction of buildings, and architects in our country. However, the official inventor of this material is considered to be a master from Germany, Otto Hetzer, who at the end of the 19th century filed a patent for bent glued forms, which included more than two boards.

The homeland of beautiful cottages made from such raw materials is picturesque Finland. The use of laminated timber as a raw material for the construction of walls in Finland began around the 70s of the last century. Traditionally, Finnish laminated timber is made from pine (Honka).

It all started with the fact that around the middle of the twentieth century, the famous construction companies In Finland, for example, Honka or Kontio began to develop innovative construction raw materials. Finnish experts decided to adopt and modernize the centuries-old knowledge of their ancestors, who erected buildings from laminated veneer lumber. The result was the most serious discovery in the construction industry - an innovative high-tech material. Since that time, laminated veneer lumber and wood processing using Finnish methods have become world heritage. This discovery has once again made wooden housing construction one of the most sought-after industries in the global construction market.

In our state, this material appeared at the end of the last century. Over the past 20 years, the production capacities of construction companies have been constantly updated, following the latest technological methods; only the most up-to-date equipment for processing timber from well-known global companies is used.

Glued laminated timber is a type of timber that consists of 2-5 lamellas (boards) obtained by longitudinal sawing of logs. At the end of sawing, the boards are dried in special chambers until a moisture level of 8-12% is obtained. After that, the boards can be combined into “packages”, glued together in such a way that the result is a bar, which is then kept under pressure in specialized presses.

Due to the implementation of longitudinal cutting, the “tension” of the timber is eliminated. It appears in the intervals of the annual rings. After eliminating the tension, the likelihood of destruction of timber during drying is eliminated. When gluing the lamellas into one beam, the core part of the trunk is placed outside, because it is characterized by a denser structure, as a result of which the beam will be less susceptible to cracking. For this reason, wooden buildings made from this raw material do not lose their attractiveness for many years. In addition, the material is characterized by high strength indicators of the interlocking connection, which guarantees a strong connection of all components and completely eliminates the risk of the formation of gaps and cracks.

Structures made of laminated veneer lumber can be erected from timber of different sections: its width ranges from 45 to 275 mm, and its height from 130 to 275 mm. Dimensions are selected by specialists based on the specific use of the structure. All cottage projects are compiled in accordance with climate standards, as well as the purpose of the future building. For example, if a family plans to live in a house only in summer period, experts recommend building it from timber 180 mm wide, and if a house is being built for permanent residence, then you should choose raw materials of at least 210, and preferably 245 or 275 mm.

When creating Finnish cottages, it is established gable roof, preventing the accumulation of snow and ice. The material used has high noise insulation characteristics. Another one distinctive feature such buildings are open terrace and a large balcony above it. Finnish buildings usually have two entrances with a vestibule, and also install large size double-hung windows. The ceilings in such cottages are low - up to 2.5 meters. Such a house must have a spacious entrance hall, a large living room and a bright kitchen; a sauna is also quite often designed during construction.

Main advantages

The main advantages of laminated timber buildings include:

  • reliability guarantee. Such structures are significantly superior to those made from conventional timber in terms of strength and durability. Most often, timber loses its aesthetic appearance due to the formation of cracks, which allow moisture and dust to penetrate, which causes the appearance of microorganisms
  • insignificant and predictable shrinkage. While walls made of solid wood shrink by an average of 7-10%, and quite unevenly, glued materials shrink by 1.5-2% and this parameter is taken into account during design
  • environmental friendliness. During the production of timber, for example, the Rovaniemi company uses exclusively timber from Lapland forests, which are one of the most environmentally friendly regions in the world. To glue boards together, a special water-based adhesive composition is used, which does not contain compounds hazardous to humans and does not damage natural properties timber.
  • quick assembly. The warm contour of a log cottage is installed in just 2-3 months, and turnkey Finnish cottages are built within 6-12 months. The duration of construction is directly proportional to the complexity of the project. But for an ordinary log building it will take from 1.5 to 2 years
  • extensive architectural possibilities. The use of glued structures can significantly expand the architectural capabilities of the cottage. The use of these materials makes it possible to increase the size load-bearing structure, windows, as well as a span width of up to 12 m, which were previously limited by the size of the log
  • ideal geometric proportions. Finnish laminated veneer lumber is produced using high-tech equipment, as a result of which high precision processing of the components is guaranteed, ensuring a tight fit of the crowns. Such a house is warmer because it is not blown by the wind and does not freeze, resulting in lower heating costs.

Projects of Finnish houses made of laminated veneer lumber

Any construction firm offers its clients a whole catalog of projects for every taste. And in each such catalog, of course, most of all are projects of classic Finnish one-story buildings made of laminated veneer lumber, because they are the most in demand. Many projects have some distinctive features. For example, the client may be offered a building with three bedrooms, a sauna and a square terrace, or elongated in length, with dimensions of 20x4 m. In the second option, inside There is a long veranda, making the area especially cozy. It is extremely rare to find projects of Finnish cottages of the usual 12x12, or 9x9. Almost all projects involve a complex configuration, multi-level roofs, which makes this style recognizable and unique. 90% of Finnish laminated timber buildings have a veranda, garage, workshop and sauna. For each individual project, a package of timber is produced in production.

The construction of a Finnish cottage on two floors will be cheaper for the customer than a one-story cottage of the same living space. You can save on roofing materials and foundation. On the websites of construction companies you can find many videos that clearly describe the construction of a two-story turnkey building. The cost of laminated veneer lumber varies widely and depends on the materials used, for example, whether Finnish or domestic laminated timber will be used. Projects are very popular two-story houses with an attic.

Standard designs for Finnish buildings are ready-made plans, developed taking into account the wishes of customers and many years of experience collected by construction companies over the years. for long years work. Finnish buildings are distinguished by their convenience and functionality. Having made a choice from the catalog, the customer can always make additions to it. Almost all projects have a couple of different layouts to choose from. Despite the fact that almost all country wooden cottages presented in the catalogs were built more than once, each new project- unique, because as a result of making additions, a standard project turns into a unique one.

The price of a Finnish cottage according to a standard project is much less than when drawing up individual project. When choosing a standard project, the customer is provided with the entire package of design documents without any additional payments.

Experts from construction companies create projects of Finnish country cottages of various levels of complexity based on personal sketches or from the client’s words. Creating a project “from scratch” is a very exciting business, during the implementation of which, together with the client, sometimes quite bold and unusual solutions are obtained. Finnish log buildings created according to a personal project most often represent the implementation of a specific architectural direction. Construction wooden structure according to an exclusive project, it gives the client the opportunity to take part in the creation of a unique exterior and interior, to create the home of his dreams, which will exude comfort.

However, during individual design It is quite difficult to predict the time of sale and the final price of the house. Therefore, it is necessary to order a wooden Finnish house in advance, so that the project is worked out in detail before the start of construction.

The construction of cottages using Finnish technology today is intensively acquiring the title of the most dynamically developing area in the construction of comfortable, energy-efficient and high-quality housing outside the city limits. Let us note that the Finnish cottage made of laminated veneer lumber has been an object of veneration and pride among the population of Finland for many decades. Construction experts use only high-quality, natural and expensive materials. Detailed elaboration of innovative techniques and active use of old Finnish traditions have made this raw material the most recognizable in the construction industry around the world.

Glued laminated timber- this is the most durable construction material, used for walls residential buildings. Designs from laminated wood 50-70% stronger than solid ones wooden structures. Shrinkage wooden houses from laminated veneer lumber is only 1-2%. The use of expensive environmentally friendly German-made adhesives and strict adherence to drying and gluing technologies allowed MAANHONKA company obtain unprecedentedly high strength indicators not only of the wood itself, but also of adhesive joints, which is confirmed by certification tests.

Finnish laminated timber

As a material for the production of high quality Finnish laminated timber our company uses polar pine or winter-cut spruce from central or northern regions Finland.

Winter cutting time is explained by the fact that with the onset of cold weather, the movement of juices inside stops. tree, the pores close and when drying the log is practically not deformed, which has a positive effect on further operational properties timber.

Glued laminated timber consists of several (from two to four) lamellas with a thickness of ~ 65 mm. Lamels are sawn parts of a solid log.

Manufacturing process production of laminated timber consists of the following steps:

  1. Drying of workpieces for production on special equipment;
  2. Carrying out the connection of lamellas using the hot gluing method with parallel pressing;
    (During the joining process, the lamellas are placed in opposite directions from each other in the direction of the “annual rings”. In this case, the adhesive seams are formed that are extremely strong, but allow moisture to pass through).
  3. Profiling and planing of workpieces;
  4. Application of a special protective composition to the surface of the workpieces.

As a result, the surface timber The result is very high quality and does not require further finishing.

Quality of laminated veneer lumber depends on the professionalism of cutting the building material.

Finnish houses made of laminated veneer lumber

MAANHONKA is devoid of such risks, since mathematical cutting accuracy is added to the experience of specialists glued blanks under the control of computers equipped production equipment companies.

When purchasing a product made in Finland, we have long become accustomed to its well-known good quality. The Finnish manufacturer will not allow a situation in which one batch of goods will be of worse quality than another. Defective goods, or goods produced in violation of production technology, will not leave the factory gates. Over time technological process production was constantly improved. Adhesive compositions, wood thickness, methods of orienting timber lamellas, thickness of workpieces, etc. were selected. The traditional accuracy, hard work and qualifications of Finnish workers remained unchanged. As a result, the result was a fairly perfect material - Finnish laminated veneer lumber.

B) Log cutting technology

In Finland, the approach to cutting wood is special. Raw logs are sawn in a strictly defined manner. Its individual parts are used only for a specifically defined group of products. The best parts of wood are used for wall or shaped products. Middle parts - for the production of floors and panels. The rest are for the production of bars, glazing beads, and efficient small moldings.

Glued laminated timber is made from a board close to the core. The lamellas are glued together with the core facing out to prevent possible tiny cracks. Finnish timber can be distinguished from afar by its characteristic “regular” wood pattern.

The blades (boards) from which the timber is made are obtained from the middle of the log. Only these boards have identical properties and it is from them that an array of laminated veneer lumber is made. These properties, common to the three boards, are transferred to the entire structure of the log. (IN technical documentation on English language glued laminated timber is translated as “tied fingers” - “finger jointed”)

In a word, laminated veneer lumber in Finland is not made from boards that were hastily purchased at favorable price, but only from that which is used for this type of product, in accordance with ISO 9000.

B) Gluing technology

For gluing, prepare a board with a moisture content of 12-13%. Gluing is carried out at a stable temperature in the workshop and, just as important, at a certain humidity. These parameters are constantly regulated by special equipment in automatic mode. At Lameco LHT Oy, adherence to technology is simply the norm.

For the production of timber the following are used: Collanon Purbond HB530 and Dynea Prefere 6000 for finger jointing; - Cascon MUF Cascomin 1240/2540 - for connecting lamellas. Gluing is done on a press with high-frequency heating (high frequency) with constantly changing polarity. The water molecule contained in the glue rotates at high speed due to its variable polarity. Due to this, the diffusion of glue with wood reaches maximum values ​​in a short period.

D) Splicing onto a furniture tenon

To obtain a good aesthetic perception of boards joined along the length, it is customary in Finland to join them on a furniture tenon with a “shelf”. From the side, a smooth (inconspicuous) line remains visible. The quality of this line is amazing. Especially Lameco. The explanation is simple - suffice it to say that the company has the most powerful press for merging lamellas in Europe. (http://en.lamecolht.fi/5).

D) Control system.

Lameco Lht Oy is part of the quality certification system Inspecta Sertifioinnti Oy (state standard). Lameco has obtained the right to use the SFS Quality Control Certificate and the “J” Quality Mark for finger jointed building materials.

E) Features.

The main secret of Finnish laminated timber and Finnish wooden houses is the whole system know-how, where everything is thought out down to the smallest details. This system is strictly implemented in production. There is no place for “simplifications” and “trifles”. Manufacturing is high-tech and capital-intensive.

Assortment of timber sizes

A wide range of standard sizes of laminated veneer lumber leaves the customer a lot of room for choice. You can choose a thin beam - for summer houses, a medium one - for comfortable living in winter, or a more prestigious one - high and wide standard size– in accordance with architectural preferences.

Finnish houses made of laminated veneer lumber are especially popular among buyers today and are highly valued by professionals in the wooden house-building market.

Glued laminated timber- This is lumber consisting of several lamellas (boards) obtained by longitudinal sawing of a log. After cutting, wood fragments selected in accordance with size and quality requirements are dried in special chambers. Then, upon reaching optimal humidity- 8-12%, boards are made into “packages”, glued along the plane, and pressed.

Thanks to the longitudinal cut, the so-called “tension” of wood that forms between the annual rings is eliminated. This eliminates the possibility of wood deformation during drying. And in the process of gluing the lamellas into a single beam, the core part of the trunk appears outside. It has a denser structure and due to this the surface is less susceptible to cracking. This is why Finnish wooden houses made from laminated veneer lumber retain an attractive appearance for many years. In addition, in the manufacture of the material, reliable locking connections, ensuring high-quality tight joining of all elements, which eliminates the risk of gaps and cracks.

Wooden houses from Rovaniemi timber are built using material of various sections: its width can vary from 45 to 275 mm, and its height from 130 to 275 mm. The size of laminated veneer lumber is usually selected based on the purpose of the future structure, as well as depending on geographical latitude, climate and terrain. For example, Finnish cottages for seasonal living are recommended to be built from timber 180 mm wide. But if you plan to live in the house all year round, then, as a rule, choose sizes 205, 243 or 275 mm. In regions with difficult climatic conditions - strong winds, long winters, low temperatures and heavy rainfall throughout most of the year - the best solution is the construction of a wooden house from laminated veneer lumber of large sections (243x275 mm and 275x275 mm). For regions with temperate climate, such as Moscow or St. Petersburg, a thickness of 205 mm is sufficient.

Finnish laminated timber is especially popular today in construction in Scandinavian style. It emphasizes the refined restraint and laconicism of Finnish architecture, its special charm.

In other styles, be it classic, modern, hi-tech, chalet or Canadian style, this material has also proven itself well. Pine wood, from which laminated veneer lumber is made, due to its plasticity and ease of processing, allows you to implement the most complex and varied ideas.

In addition to suburban residential construction, Finnish glued material is also widely used in the construction of non-residential buildings: bathhouses, hotels, churches, etc. Especially for the construction of objects within the city, TM Rovaniemi presents a unique lock for connecting timber - “city-corner”. Given gusset It is highly durable and makes any structure not only reliable, but also aesthetically attractive due to the absence of protruding crowns at the corners.

Advantages of a Finnish house made of laminated veneer lumber

Finland is a world leader in the field of wooden housing construction. The forest-rich country is famous for the high quality of its wood, advanced production technologies, and adherence to fashion trends and fresh design ideas. In addition, wooden houses from Finland are invariably associated with environmental friendliness and a special atmosphere of warmth and comfort. A unique invention of Finnish craftsmen - laminated veneer lumber - the main material used in construction. Finnish timber houses successfully exported to the most different countries peace. In Russia they have also gained great popularity: not only in Moscow and St. Petersburg, but also in other remote regions of our country, many projects using this technology have already been successfully implemented.

Despite the fact that the cost of houses made of timber is slightly higher compared to traditional ones, many of our clients choose to build country house exactly this material.
And there are many reasons for this:

  • Reliability. Houses made from Rovaniemi laminated veneer lumber are significantly superior in strength and durability to buildings made from traditional building materials. As a rule, wood loses its aesthetic appearance due to the appearance of cracks - moisture and dust get into them, which can lead to the appearance of fungus and mold. A special production technology minimizes the susceptibility of wood to cracking and helps preserve the pristine beauty of the cottage for many years.
  • Low and predictable shrinkage. The shrinkage of a house made of laminated veneer lumber occurs evenly and is only 1-2% - this is 5 times less than the shrinkage of a structure made of solid wood. The low shrinkage rate of glued materials can significantly speed up the construction process.
  • Environmental friendliness. In the production of Rovaniemi timber, wood from Lapland forests is used - one of the most environmentally friendly parts of the planet. The gluing of the lamellas is carried out using environmentally friendly modern glue on water based. It does not have a harmful effect on human health, and also does not deprive the tree of its ability to “breathe”.
  • Short time assemblies. As Rovaniemi's long-term practice shows, warm contour timber houses assembled in 1.5 - 3 months. A Finnish houses turnkey laminated veneer lumber can be erected within 6-12 months, depending on the complexity of the project. For comparison: building a traditional log cottage takes from 1.5 to 2 years (including the time required for shrinkage).
  • Wide architectural possibilities. The architectural potential of a structure made from glued laminated structures is truly great: there are no restrictions on the length of the timber, window openings and the width of the spans allows you to implement any solutions.
  • Flawless Geometry. Finnish laminated veneer lumber is produced using the most modern equipment, which guarantees high precision processing of parts, which, in turn, ensures a tight fit of the crowns. Due to this, the house becomes warmer, since it is not blown by winds and does not freeze, and the costs of its heating and operation are reduced.
