When deciding on housing for ourselves and our family, each of us strives to find the best - a cozy, environmentally friendly area, the “right” construction company, best designer... And, of course, high-quality building material. And it increasingly happens that after sifting through a bunch of literature and receiving a lot of advice, people return to what has been tested by many generations in many countries - they choose wooden houses.
Such a choice today could be called a “return to origins”, if not for one significant “but”. Housing construction technologies are constantly being improved and are modern wooden houses They are in no way inferior to their “brothers” made of stone, brick or concrete, and in many respects they even surpass them. Wooden houses provide their residents not only with comfort, coziness and environmental friendliness, but also with high levels of safety, durability, and efficiency. Especially if we're talking about about housing made from modern natural material, which appeared in our country relatively recently, but is already rapidly gaining popularity. Of course, you already guessed what we are talking about - this is laminated veneer lumber.
Of course, it’s no secret that wood is a “living” material, organic, and therefore delicate. Many factors environment- from ultraviolet radiation to fungi and insects - negatively affect wood structures and contribute to its aging and destruction. Fortunately, all these issues can be resolved. Today, there are many tools and technologies that can neutralize these factors, make their influence insignificant or completely eliminate them. The only drawback This method is that it also requires some investment of time and money.
That is why it is so in demand today laminated veneer lumber- he has a much more flexible “character”, practically without losing the advantages of a solid natural wood. Glued laminated timber You can even call it a perfect material, and this will practically not be an exaggeration.
The first is not obvious, but very important advantage of the material in question - laminated veneer lumber It is impossible to produce what is called “on the knee”, in artisanal conditions. Its production requires well-established production using expensive equipment. It's complicated technological process, which includes several stages.
At the first stage of production, a high-quality log is cut into boards of the required thickness and dried until optimal humidity, after which the workpiece will be processed to an ideal geometric shape. Next, the treated boards are turned into lamellas, spliced along the length. Then the lamellas undergo a thorough quality check and treatment with the necessary protective compounds and glued together in a press under high pressure, using water-based glue. The glue, being environmentally friendly, does not affect the breathability of wood and its natural properties, allowing it to maintain full air circulation. After final processing and profiling, the result is high-quality and ready for use. laminated veneer lumber for a wooden house. With this technology, the risk of acquiring poor quality material is reduced to almost zero.
Besides, laminated veneer lumber is a construct - that is, it is structured and strict parameters can be applied to it. Consequently, documentation is provided for it, which clearly indicates these same parameters, for example, humidity, density, storage conditions and others. Accordingly, a house made of laminated veneer lumber is built according to the results of precise calculations.
One of the main arguments presented by opponents of construction wooden houses, is the fact that the tree is deformed over time, dries out and gives a very significant shrinkage. Yes, indeed, wood has this property, and shrinkage ordinary timber or logs can reach 10-15%. But the technology for producing laminated veneer lumber requires careful drying of the wood, therefore, after the construction of the house, deformation of any kind is practically eliminated - even with a sharp change in atmospheric conditions.
In general, stability of shape and size is perhaps one of the most important factors when choosing a building material, especially when it comes to wood. Glued laminated timber V in this case - right choice. Due to the fact that the wood is not only dried before gluing, but also undergoes strict quality control, shrinkage ultimately does not exceed 1%. This, among other things, means that finishing work can begin immediately after wooden house will be collected. Moreover, since laminated veneer lumber at home does not cause shrinkage, practically eliminating the formation of cracks and crevices in an already built house.
However, the choice of such material as laminated veneer lumber, in general, significantly reduces the time required at almost every stage of building a house. Another one of him distinguishing feature thing is laminated veneer lumber It is manufactured at the factory in conditions close to ideal, at a constant temperature and humidity that is optimal for wood. And all the components of the future structure are carefully adjusted, checked and supplied with accompanying documentation. In fact, on construction site The finished wooden house arrives in disassembled form, and all that remains is to assemble it, like a designer - according to the prepared documentation. In some cases, the construction time for a house made of laminated veneer lumber can be only 3-4 weeks!
Also, the speed of putting a house into operation (and, let’s note in passing, the cost of the property as a whole!) is also influenced by the fact that laminated veneer lumber, thanks to high quality surface, practically does not require subsequent decorative processing. Its production technology assumes that all knots, stains, and any other defects will be rejected, and the workpiece will be perfectly matched in color and texture. Glued laminated timber – beautiful and aesthetic, like any wood, has an impeccable appearance.
By the way, to the question of aesthetics and architecture. Glued laminated timber provides great scope for the imagination of architects: it allows you to design and construct multi-story and spacious buildings without worrying about uneven loads, reliability of floors and the need for additional load-bearing walls. The high strength of the material allows you to create beams reaching a length of 20 meters. Such a beam can withstand heavy loads without requiring the installation of additional supports. Thereby laminated veneer lumber can be used in the construction of structures such as swimming pools.
Glued laminated timber allows you to save significantly even on the “basis of the foundations” of the house: the lightness of this material allows you not only to build a house on an inexpensive shallow foundation, but also in some cases to use an existing foundation. Thanks to its lightness and stability, it makes it possible to build buildings on any type of soil and in any geological conditions.
Wooden houses, the material for which was laminated veneer lumber, have high heat specifications not only due to the natural properties of wood. The natural thermal insulation and breathability properties of natural wood make it possible to eliminate the need for additional insulation. And the tight connection of the beams during assembly is due to the need for additional sealing of the joints.
Additionally, laminated veneer lumber makes it possible to carry out hidden wiring engineering communications, for example, in floors, posts and beams. This also reduces the cost of carrying out additional work and allows you to maintain the attractive appearance of the building. Also, thanks to treatment with modern antiseptics and fire retardants, laminated veneer lumber reliably protected from most external influences: moisture, fire, insects.
Of course, with all the advantages of the material considered, we should not forget that building a house from laminated veneer lumber does not tolerate unprofessionalism, but, on the contrary, requires the appropriate qualifications, organization and experience from the craftsmen. If these conditions are met, a house made of laminated veneer lumber will delight its owners with its beauty, comfort and reliability for a hundred years!

If speak about physical and mechanical properties, then Siberian cedar, or Siberian pine, occupies an intermediate position between fir and spruce. Cedar wood is easy to process and very durable.
Laminated cedar beams: pros and cons
Cedar wood has a number of positive properties, such as strength, ease of processing, interesting options textures and colors, pleasant aroma and released antibacterial volatile substances - phytoncides. Only in rare cases should you choose wood of a different species instead.
Advantages of cedar profiled timber
Thanks to special processing, cedar wood acquires increased durability. Glued laminated timber from this species is used in wooden house construction.
Cedar is especially good in those structures and components where large differences in pressure and humidity conditions are expected. In this regard, it competes with Scots pine.
As you would expect, this type of wood has beautiful wood grain and color. Therefore, laminated cedar beams occupy a strong position among materials for the construction of a wooden house.
Cedar lives 200-300 years, has a straight trunk, reaching an exceptional diameter - up to 1.8 meters, and up to 40 m in height. Of all the sound wood species, cedar has the lightest and softest wood.
The cedar core is narrow and has a pinkish tint. The color contrasts with the yellowish-white wide sapwood.
Late wood is usually poorly developed and smoothly transitions into early wood. It is moderately resistant to cracking and rotting, is easy to work in all directions and has a beautiful, unique texture.
Siberian cedar, growing in the extremely cold conditions of the taiga, has unique heat-insulating properties. Cedar timber is stronger than some metals.
In Rus', cedar was often used to build houses, log houses and baths. Cedar resin can repel insects and destroy putrefactive bacteria.
If your house is built of cedar, the tree will provide you with healthy deep sleep and a beneficial atmosphere in the house. this means that you will prevent many diseases of the nervous system.
Properties of this coniferous tree unique from a health point of view. It is rich in essential oils and phytoncides.
When heated, cedar releases an exceptionally beneficial aroma of cedar balsam. Source of aroma - essential oils, which fight many types of pathogens.
A house made of cedar beams is beneficial for human health for a long time. Cedar wood has a heterogeneous brownish-pinkish color.

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 significant shrinkage deteriorated the appearance of the 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:
- The shrinkage of the house 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 level 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.

Being one of the best manufacturers profiled laminated veneer lumber in Siberia, we supply house kits for assembly and build turnkey wooden houses according to individual and standard designs. Houses made of laminated veneer lumber from the NB Company are successfully operated in Russian cities from Yuzhno-Sakhalinsk to Moscow.
When humidity changes, laminated veneer lumber does not change its shape, that is, it does not “lead”, does not crack and remains with a smooth, beautiful surface.
Production process:
Sawing
- drying
- gluing
After gluing operation finished timber undergoes profiling on four-sided machines. This is one of the most critical moments in the manufacture of laminated veneer lumber. The quality of the entire timber and, ultimately, the quality of the future home depends on the accuracy of manufacturing the tongue-and-groove joint. After giving the laminated veneer lumber a profile, it ends up to the size of high accuracy, cut into elements required size in accordance with the working draft. The final stage of manufacturing laminated veneer lumber is cutting crown cups into it on special cup-cutting machines and drilling holes for dowels and special metal rods - “studs”.
In terms of durability, laminated veneer lumber is not inferior to all others wooden structures. (cm.
