They began to build houses from laminated veneer lumber in Siberia due to the high quality characteristics of the material. Such houses shrink less, walls crack less, and their thermal insulation properties are suitable for harsh climates. Houses made of laminated bursa in Irkutsk are loved both as large cottages and as small ones country houses. Bathhouses, garages and other buildings are built from laminated veneer lumber in Irkutsk. This article is about the cost and quality of houses made of laminated timber in Irkutsk.
Houses made of ordinary wood have always been favorably distinguished by their thermal insulation and aesthetic qualities from brick and concrete buildings. But due to low temperatures in Siberia, it was necessary to build from timber with a cross-section above 180 mm. And this brought with it a number of inconveniences:
- Involvement of additional equipment, since the timber weighed quite a bit.
- The 180 mm thick walls without additional insulation were still not suitable for living in the winter.
- Cracking and large shrinkage worsened appearance house, which subsequently had to be finished.
- The moisture content of timber with a cross-section of 180 mm or more does not always correspond to that stated by the manufacturer, since drying such a cross-section is difficult and time-consuming.
All these problems faded into the background with the advent of laminated veneer lumber. Homes have become more resistant to low temperatures, and the walls can be built with less thickness. All the advantages are associated with quality characteristics material:
- House shrinkage is minimal, from ordinary timber it is exactly 10-15%.
- The thermal conductivity of the walls of a house made of laminated veneer lumber is 30% less than that of similar walls made of wood or regular timber.
- There are no cracks, inaccuracies in shapes or cuts in the bowls.
- The walls of the house are more durable due to the gluing of the lamellas in the opposite direction of the fibers, the drying of each lamella, and the quality of the wood, which undergoes careful selection at the manufacturing stage.
- Because of the ease and correctness geometric shapes houses made of laminated veneer lumber in Irkutsk are erected in 2-3 weeks.
- Wall decoration, both internal and external, is not necessary.
- The fire resistance of glued material walls is higher due to additional processing, the density of glued lamellas, and a more even texture. Also, such a house rots less and is not so afraid of moisture, since there are fewer microcracks.
- The price of glued ohms in Irkutsk starts from 16 thousand/ruble m2, this also makes them attractive to residents of Siberia.
From production to construction site
Manufacturers in Irkutsk use raw materials from Siberia to produce laminated veneer lumber for houses. Northern forests are famous for their density, so the lamellas made from it are durable and have a uniform texture. This product also speaks in favor of a small amount of“handicraft” manufacturers, since its production requires expensive equipment.
The wood is dried in special chambers and only then, after automatic selection, lamellas are made from it. Automatic selection allows you to completely eliminate the “human factor”, namely: violation of the correct shape up to mm, the presence of dead rotten knots, the presence of blue stains, microcracks and other defects. Then the lamellas are glued into 12 m lamellas and only then glued under a press into a beam of the required section. All types of sections are made in Irkutsk, but for houses the most suitable material from 180 mm.
On special machines, the finished laminated veneer lumber is profiled and the bowls are cut into a certain model Houses. In Irkutsk you can build a house from laminated veneer lumber simple type. But the profiled version is more suitable, since its connection is tighter and the walls are stronger. For construction country house or baths, you can use a non-profiled glued version.
You can hear reviews about the uneconomical nature of such a house. But large Irkutsk manufacturers use only the highest quality adhesives that do not interfere with air circulation in the room and do not emit harmful fumes. The most commonly used adhesives are: AKZO NOBEL (Sweden) KLEBCHEMIE (Germany).
Then the house elements are assembled in production and the accuracy of cutting the bowls is checked. Only after this the timber is packaged in waterproof film and delivered to the construction site.
How to build a house easier and cheaper
Buyers in Irkutsk have two options for building a house from laminated veneer lumber: purchasing the material from a manufacturer or dealer + hiring a construction team, or ordering a turnkey service. Let's consider the pros and cons of such construction in the form of a table:

Advantages of laminated veneer lumber
Laminated timber is one of the most popular building materials today. This is facilitated by a number of its features:High structural strength
The strength of laminated veneer lumber exceeds the strength of solid wood structures by an average of 60%.
Stability of geometric shapes, absence of internal “tension”
Having decided to build a house from laminated veneer lumber, you can be sure that the building will not shrink, and individual elements, from which its walls are made, will not be deformed.
No defects on the finished material
Each workpiece is carefully checked for defects, all of them are selected according to texture and color. This is also facilitated by the use of high-quality adhesives that minimize the risk of cracks. Buildings made of laminated veneer lumber, even many years later, retain the original appearance and strength of the walls.
Excellent thermal properties
Glued laminated timber has low thermal conductivity. IN winter period the walls retain heat and keep the heat out in summer.
No need for finishing work
Walls made of laminated veneer lumber are smooth, smooth surface, which allows you to save on the purchase of finishing materials.
High resistance to microorganisms and fungi
Structural features of the material, its processing by special means, preventing rotting, as well as the presence of adhesive layers, prevent bacteria and wood pests from penetrating deep into the wood.
Efficiency of construction work
In Siberia, as in any other city, this indicator is of particular importance for builders. A team of 6 people is enough to erect a building with an area of about 100 m2 in a month.
No need to build a strong foundation
Buildings made from laminated veneer lumber are lightweight and yet highly durable. Installation of the foundation is not necessary, which saves time and money spent on construction.
Low shrinkage rates
This property allows you to start finishing immediately after completion of the main construction work.
Environmental friendliness
Buildings made of laminated veneer lumber are completely safe for human health. In addition, the material maintains an optimal indoor microclimate due to its “breathability” (natural regulation of humidity levels).
Glued laminated timber: what types of this material are sold
They sell several types of laminated veneer lumber:- fencing, for non-load-bearing partitions;
- structural, for load-bearing walls;
- single layer;
- multilayer.
Material of manufacture and properties of laminated timber
The essence of the process of producing laminated veneer lumber is gluing individual boards of certain sizes together using adhesives. These boards can be made from different breeds coniferous trees:- pine;
- Siberian cedar pine;
- cedar;
- larch (some species);
- Douglas fir (used only in the USA, Canada, Japan).
- melamine This adhesive composition is used for the manufacture of long-span timber. Used in Russia and European countries. Color – transparent.
- resorcinol. Used in the manufacture of structures intended for external walls that must withstand high levels of humidity. Mainly used in the USA and Japan. Color – dark.
- polyurethane. A quick-hardening adhesive that allows the production of laminated veneer lumber several times faster. Makes it possible to glue wood with a humidity level of up to 18%. Color – transparent.

Construction from laminated timber, product selection
Information about the main stages of construction of buildings made of laminated veneer lumber will allow customers to adequately assess the qualifications of craftsmen and keep the quality of work under control:- Project creation, approval technical nuances, drawing up estimates, determining the cost of work.
- Laying the foundation. Due to the lightness of laminated veneer lumber, a powerful foundation is not laid under it. If the area is not characterized increased level groundwater, the height of the foundation will be 0.5-1 meter high.
- Installation of the building frame according to the project.
- Roofing works according to the project.
- Connecting your home to communications engineering networks and electrical system.
- Domestic Finishing work according to the customer's wishes.
The first and most important point What you should pay attention to when choosing a building material is its purpose.
Other options are also possible:
House made of laminated timber for permanent residence
To create comfortable living conditions in a house made of laminated veneer lumber, where you plan to live permanently, you should opt for building material with a cross section of 200-250 mm, having a heat transfer of 1.3 m°C/W. This thickness is quite enough to create a comfortable temperature regime, even on frosty days. An economical option for such a house is walls made of timber with a cross-section of 140 mm with a thermal resistance of 1 m°C/W, insulated on the outside with penoplex or Ursa. On top of the insulation is decorative cladding.
House made of laminated veneer lumber for seasonal living
If you use the house during the first night frosts, then it is better to choose material with a cross-section of 160-180 mm. This wall thickness will withstand temperatures within 1-2 degrees below zero. If you leave the house before the first cold snap sets in, you can purchase timber whose thickness is 140-150 mm. Additional insulation There is no need to do walls.
You should also pay attention to the following points:
Origin of the tree
If the wood for production is brought from the northern regions, then it will be much better quality than wood from the southern regions. The cheapest, and therefore low-grade, wood is considered to be from swampy areas.
Wood type
Middle class - pine or spruce. Low grade - pine and spruce slats, mixed. You can distinguish pine from spruce by the number and size of knots. Pine has few of them, but they are larger.
Type of timber
The material must match technical specifications, where tolerances are specified for the number of knots and the presence of defects. If the seller says that laminated veneer lumber complies with GOST, this does not at all guarantee the quality of the material, since GOST has too many tolerances.
Types of laminated veneer lumber sold:
Material warranty:
If the manufacturer provides a guarantee on the material, this is a big plus. Immediately clarify the point about replacing defects, reporting stock, the type of profile used, the possibility of cutting wind pockets in the bowls.
Length of laminated timber:
By the length of the proposed timber you can find out what equipment is used for its production. If a manufacturer offers timber 12 meters in length, this means that modern equipment is used that is capable of producing such long lamellas. Old equipment is capable of producing timber up to a maximum of 6 meters in length. Pay attention to the length of the face boards. The longer they are, the more quality wood was used. Higher grades– boards are 1.5-2 meters on average, but such timber is usually used in shipbuilding; for wall construction, lower grades of timber can be used.

Timber harvested in winter has a long list of advantages: it is more durable.
The minimum content of juices and sugars in the winter forest reduces the likelihood of fungi, mold, rotting, and the appearance of blue and black spots.
Its own raw material base allows the Shelekhovsky woodworking plant to confidently declare - here you will be offered exclusively winter forest excellent quality.
Correct cutting
Sawing logs into boards, from which timber is subsequently glued, is carried out in different ways.
The most common method is mixed cutting, which is simpler and cheaper. With this option, the quality of the board is noticeably worse. During operation, the boards begin to crack at the joints of the annual rings, become brittle and peel off.
The most successful is the ex-log method - cutting through the core of the log. Boards obtained in this way are more durable and look more aesthetically pleasing. As a result, laminated veneer lumber looks more textured and more expensive.
The Shelekhovsky plant uses the second cutting method - tangential or ex-log. The Swedish ARI circular saw line is responsible for proper sawing.
Drying boards
Despite the fact that winter harvested wood has low humidity, the boards still need to be thoroughly dried. At this stage, the natural disadvantages of wood are minimized - susceptibility to various fungi and blackening. But only if drying is carried out in a soft mode.
Ideal conditions are created in special drying chambers oh and they require from 10 to 30 days. Unfortunately, many companies cannot afford to wait that long - it slows down the entire production process.
The Shelekhovsky woodworking plant has 17 drying chambers with a total loading volume of 2,400 cubic meters. meters. This allows us to guarantee that construction deadlines are met without disruptions or delays, even in the high season.
Processing (planing) of boards
Preliminary calibration helps to identify falling knots and resin pockets in the board.
The result is a lamella - a perfectly flat board ready for splicing.
To maintain the correct temperature regime, a return system was installed at the Shelekhovsky woodworking plant warm air Dantherm Filtration (Denmark). And even if you comply necessary conditions At the factory, they strictly ensure that after planing the lamellas, they wait no more than an hour for the next stage.
Merging of lamellas
The stage at which an important characteristic is determined - the length of the future laminated veneer lumber; it can vary depending on the project of the house and reaches 12 meters. The merging of lamellas at the Shelekhovsky woodworking plant takes place on an automated line made by German manufacturer Weinig, a world leader in the industry.
A specialized workshop (which not every manufacturer has) allows the Shelekhovsky plant to produce laminated veneer lumber up to 12 meters long. This means that the number of seams and joints on the walls of the house is reduced to a minimum.
ShelDoZ offers another unique technology, developed by the plant’s specialists - radial splicing of lamellas. The method resembles the manufacturing technology furniture board, providing additional strength to the product. In addition, timber with radial lamellas fused looks so exclusive that the walls easily become the main decoration of the house!
Pressing lamellas
The stage at which spliced lamellas are transformed into laminated veneer lumber - a natural high-tech material with excellent quality. At this stage, two characteristics are important - the quality of the glue used and the possible maximum width of the beam.
It is important that the air temperature in the processing workshop is maintained at 20 degrees Celsius. Otherwise, the wood begins to dry out on top, which in the future can have a bad effect on the quality of the product.
The German heavy press LHP 14 series, used at the Shelekhov plant, is capable of pressing any type of wood, including durable larch, because the process provides a pressure of more than 12 kg. per 1 sq. cm. It is a high-quality press that ensures the final width - than better equipment, the thicker, and therefore stronger, the walls of your house will be.
ShelDoZ uses environmentally friendly glue on water based(Norway), without toluene and formaldehyde. The glue has a European quality certificate for the production of structural timber.
Shelekhovsky woodworking plant offers interesting combinations various breeds wood in one beam, for example, the outer part is made of cedar, and the inner part is made of spruce or pine. Possible options- 240x240 mm or 280x280 mm for external walls, 180x240 mm. for structural beams and interior walls.
Profiling timber
At this stage, the laminated veneer lumber is profiled for further cutting into parts of the house kit.
Technological machineRekor Mida at the Shelekhov plant is capable of parallel planing and milling of timber on all four planes. Processing occurs automatically, without using manual labor, which guarantees smooth surfaces, even and clear cutters. The maximum possible beam cross-section for RekorMida 300x500 mm is a record for the region.
Designing a multifaceted house model for cutting
The high-precision woodworking complex Hundegger K2 (Germany) requires a specialized house design, in which every detail is calculated down to the millimeter.
At this stage, the house design developed by the architects is transferred to the programCAD-Work, designed to prepare files onHundeggerK2. According to this individual multidimensional model the equipment subsequently produces all the parts of the house.
The only one in the regionHundeggerK2 and design specialist inCAD-Work work at the Shelekhovsky woodworking plant.
Today, window laminated timber is one of the popular types of lumber. The humidity of these products is about 10%, which is achieved thanks to a special drying method. Compared to standard timber, this product has high quality characteristics, strength and resistance to various impacts.
The Siberia LLC company is engaged in the production of Tule window beams. Having our own raw materials and production base for the manufacture of these products allows us to provide high-quality products in a short time. We produce the following types of sections - 72x86 and 82x86, with a length of 3 meters or more.
Window beams can be divided into three categories:
- The middle lamella is spliced along the length, the two front lamellas are solid.
Dimensions:
Cutting: semi-radial and radial cutting for external lamellas, tangential and semi-radial - for internal ones.
Splice step: for the internal lamella - 150 mm, for the external one it is solid along the entire length.
- Two lamellas are fused along the length, one front one is solid.
Dimensions: 72x86, 82x86 and length from three meters.
Cutting: radial or semi-radial cut for two external lamellas, tangential and semi-radial - for the front
Splice step: for internal lamellas - 150 mm, for external ones - 300 mm.
Use is not allowed: resin pockets more than 20 mm, rot, knots and cracks.
- All lamellas are spliced along their length using specialized glue.
Dimensions: 72x86, 82x86 and length from three meters.
Cutting: internal and external lamellas of radial or semi-radial cut.
Splice step: for internal lamellas - 150 mm, for external ones - 250 mm.
Use is not allowed: resin pockets more than 20 mm, rot, knots and cracks.
Characteristics of laminated veneer lumber.
Window timber has increased resistance to various influences, such as rotting, due to the low humidity of the products. Wood coniferous species contains resinous substances that are a natural antiseptic, which makes these breeds the most popular in this area.
Due to its structural characteristics, laminated veneer lumber for windows is less susceptible to various humidity and temperature deformations, in contrast to solid wood. These products are more durable and have the principle of equal strength in all directions. They also do not have wood defects, such as cracks and knots, which impair strength and appearance.
During operation, glued products do not change their shape, are resistant to cracking and high level quality of front surfaces. Also, this type of product has very low shrinkage - up to 3 times less than sawn timber.
Most often, pine and spruce are used to produce laminated veneer lumber for windows. Larch and cedar are used less frequently.
Window timber production methods
Production window beam is carried out by gluing three lamellas of radial and semi-radial cuts along the thickness. The moisture content of the timber is reduced by relieving stress due to the thinner thickness of the lamellas compared to solid wood. Wood warping is minimized through the use of gentle drying modes in convection chambers. After drying, the workpiece is calibrated.
The lamellas are checked for defects, sorted and quality-reducing defects are removed. Then the blanks are spliced along their length using specialized glue. The next stage in the production of window beams is calibration, which is carried out by planing the product on four sides.
The lamellas are glued together into timber using a specialized press. The glue used does not have moisture-proofing properties, so the entire solid wood “breathes”.
Humidity is 10-12% and, as a result, minimal shrinkage(less than 1%) - finishing work can be carried out immediately after installing the roof;
A special profile lock firmly and accurately positions the beam in the wall relative to the above and underlying crown;
High strength and physical and mechanical properties, rigidity, clear geometry and structural stability;
Fast construction time (ready-made construction kit with pre-cut bowls), without the need to order a faucet;
Possibility of use for covering long-span structures;
Heat transfer resistance exceeds similar characteristic solid wood almost doubles, since the structure of the timber is more uniform and free of cracks. For example,the thermal conductivity of a 150x150 beam is approximately the same as a log with a diameter of 240 mm;
Resistance to various climatic conditions, biological factors (insects, fungus);
Production in accordance with DIN, GOST standards. Wood species: spruce, pine, larch, cedar.
Glue: 1-component, polyurethane Purbond (Switzerland), class D4, environmentally friendly, certified.
Sections: 140/160/180/200/240 (h) * 80/120/160/200/240, length up to 13 m.
Surface quality: planed, roughness up to 200 microns.
