Being one of the best manufacturers profiled glued laminated timber in Siberia, we supply house kits for assembly and build "turnkey" wooden houses according to individual and standard projects. Houses from glued laminated timber from the NB Company are successfully operated in the cities of Russia from Yuzhno-Sakhalinsk to Moscow.
When humidity changes, glued laminated timber 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 the gluing operation finished timber passes profiling on four-sided machines. This is one of the most crucial moments in the manufacture of glued beams. The quality of the entire timber and, ultimately, the quality of the future home depends on the accuracy of the manufacture of the tongue-and-groove connection. After giving the glued beam a profile, it ends up in size with high precision, cut into elements required size in accordance with the working draft. The final stage in the manufacture of glued laminated timber is the “cutting” of crown cups in it on special cup-cutting machines and drilling holes for dowels, special metal rods - “studs”.
In terms of durability, glued laminated timber is not inferior to all others wooden structures. (cm.
Humidity 10-12% and, as a result, minimum shrinkage(less than 1%) - finishing work can be carried out immediately after the installation of the roof;
A special profile lock rigidly and accurately bases the beam in the wall relative to the above and below the crown;
High strength and physical and mechanical properties, rigidity, clear geometry and structural stability;
Fast construction time (ready-made constructor with cut bowls), without the need to order a crane;
The possibility of using for overlapping large-span structures;
Heat transfer resistance exceeds similar characteristic massive wood is almost doubled, since the structure of the timber is more uniform and free of cracks. For example,the thermal conductivity of a 150x150 timber 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. Wood species: spruce, pine, larch, cedar.

When deciding on housing for ourselves and our families, each of us strives to find the best - a cozy, environmentally friendly area, the “right” construction company, the best designer… And, of course, high-quality building material. And more and more often it happens that having shoveled a bunch of literature and received 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 the roots”, if not for one significant “but”. Housing construction technologies are constantly being improved and modern wooden houses they are in no way inferior to their "brothers" made of stone, brick or concrete, and in many respects even surpass them. Wooden houses provide their residents with not only comfort, coziness and environmental friendliness, but also high rates of safety, durability, efficiency. Especially if we are talking about housing made of modern natural material, which appeared in our country relatively recently, but is already rapidly gaining popularity. You, of course, have already guessed what we are talking about - this is glued laminated timber.
Of course, it's not a secret for anyone that wood is a "live", organic material, and therefore delicate. Many factors environment- starting from ultraviolet radiation and ending with fungi and insects - they negatively affect wood structures and contribute to its aging and destruction. Fortunately, all these issues are solvable. To date, there are many tools and technologies that can neutralize these factors, make their influence insignificant or completely nullify. The only downside This method is that it also requires some time and money.
That is why today is so in demand glued laminated timber- it has a much more accommodating "character", practically without losing the advantages of a solid natural wood. Glued laminated timber one can even call it a perfect material, and this will practically not be an exaggeration.
The first is not obvious, but a very important advantage of the material under consideration - glued laminated timber it is impossible to produce what is called “on the knee”, in artisanal conditions. Its production requires well-established production with the use of expensive equipment. It's complicated technological process, which includes several stages.
At the first stage of production, a high-quality log is unraveled into boards of the required thickness and dried to optimal humidity, after which the workpiece will be processed to an ideal geometric shape. Further, the processed boards are turned into lamellas, spliced along the length. Then the lamellas undergo a thorough quality check, processing with the necessary protective compounds and glued on the press under high pressure, using a water-based adhesive. The glue, being environmentally friendly, does not affect the air permeability of wood and its natural properties, allowing it to maintain full air circulation. After finishing and profiling, a high-quality and ready-to-use product is obtained. glued timber for wooden house . With this technology, the risk of acquiring poor quality material reduces to almost zero.
Besides, glued laminated timber is a construct - that is, it is structured and strict parameters can be applied to it. Therefore, documentation is provided for it, in which these same parameters are clearly indicated, for example, humidity, density, storage conditions, and others. Accordingly, a house made of glued laminated timber is being built according to the results of accurate 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 such a property, and shrinkage ordinary timber or logs can reach 10-15%. But the technology for the production of glued laminated timber involves a thorough drying of the wood, therefore, after the construction of the house, deformation of any kind is practically excluded - even with a sharp change in atmospheric conditions.
In general, shape and size stability is perhaps one of the most important factors when choosing a building material, especially when it comes to wood. Glued laminated timber 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 you can proceed to finishing work immediately after wooden house will be collected. In addition, since glued timber at home does not shrink, the formation of cracks and crevices in an already erected house is practically excluded.
However, the choice of material glued laminated timber, generally significantly reduces the time at almost every stage of building a house. Another one of his distinguishing feature thing is glued laminated timber is manufactured at the factory under conditions close to ideal, at a constant - optimal for wood - temperature and humidity. And all the components of the future structure are carefully adjusted, checked and supplied with accompanying documentation. In fact, on construction site a finished wooden house arrives disassembled, and it remains only to assemble it, as a designer - according to the prepared documentation. The term for building a house from glued laminated timber in some cases can be only 3-4 weeks!
Also, the speed of putting the house into operation (and, we note in passing, the cost of the object as a whole!) Is also affected by the fact that glued laminated timber, thanks to high quality surface, practically does not require subsequent decorative processing. The technology of its production assumes that all knots, spots, and any other defects will be rejected, and the workpiece is perfectly matched in color and texture. Glued timber - beautiful and aesthetic, like any wood, it has an impeccable appearance.
By the way, to the question of aesthetics and architecture. Glued laminated timber provides a lot of scope for the imagination of architects: it allows you to design and build multi-storey and spacious buildings without worrying about load unevenness, reliability of ceilings and the need for additional bearing walls. The high strength of the material allows you to create beams reaching a length of 20 meters. Such a beam is able to withstand heavy loads without requiring the installation of additional supports. Thereby glued laminated timber can be used in the construction of structures such as swimming pools.
Glued laminated timber allows you to significantly save even on the “base 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 in some cases also use an existing foundation. Due 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 glued laminated timber, have high heat specifications not only due to the natural properties of wood. Natural indicators of thermal insulation and breathability of natural wood make it possible to refuse additional heaters. And the tight connection of the bars during assembly - from the need for additional sealing of the joints.
Additionally, glued laminated timber makes it possible to carry out concealed wiring engineering communications, for example, in floors, pillars and beams. This also reduces the cost of additional work and allows you to maintain an attractive appearance of the building. Also, thanks to the treatment with modern antiseptics and flame retardants, glued laminated timber protected from most external influences: moisture, fire, insects.
Of course, with all the advantages of the considered material, one should not forget that building a house from glued laminated timber does not tolerate unprofessionalism, but, on the contrary, requires appropriate qualifications, organization and experience from the craftsmen. Under these conditions, a house made of glued laminated timber will delight the owners with its beauty, comfort and reliability for a hundred years!

Advantages of glued laminated timber
Glued 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 glued beams exceeds the strength of solid wood structures by an average of 60%.
Stability geometric shapes, lack of internal "stress"
Having decided to build a house from glued beams, you can be sure that the building will not shrink, but individual elements, from which its walls are made, will not be deformed.
No defects on the finished material
Each blank is carefully checked for defects, all of them are selected for texture and color. This is also facilitated by the use of high-quality adhesives, which minimize the risk of cracking. Buildings made of glued laminated timber, even many years later, retain their original appearance and strength of the walls.
Excellent thermal properties
Glued timber has a low thermal conductivity. AT winter period walls retain heat, and in summer they do not let the heat through.
No need for finishing work
Walls made of glued laminated timber are characterized by smooth, smooth surface, which allows you to save on the purchase of finishing materials.
High resistance to microorganisms and fungus
Structural features of the material, its processing by special means, preventing rotting, as well as the presence of adhesive layers, does not allow bacteria and wood pests to penetrate 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 of glued laminated timber are lightweight with their high strength. Installation of the foundation is optional, which saves time and money spent on construction.
Low shrinkage
This property allows you to start finishing immediately after the completion of the main construction works.
Environmental friendliness
Glulam buildings are completely safe for human health. In addition, the material maintains an optimal microclimate in the room, due to its “breathing ability” (natural regulation of the humidity level).
Glued laminated timber: what types of this material are sold
sell several types of glued beams:- enclosing, for non-bearing partitions;
- structural, for load-bearing walls;
- single layer;
- multilayer.
Production material and properties of glued beams
The essence of the process of production of glued beams is to glue individual boards of certain sizes together with the help of 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 large-span timber. Used in Russia and European countries. Color - transparent.
- resorcinol. It is used in the manufacture of structures intended for external walls, which must withstand high level humidity. Mainly used in USA and Japan. Color - dark.
- polyurethane. Quick-setting adhesive that allows you to produce glued laminated timber several times faster. It makes it possible to glue wood with a moisture level of up to 18%. Color - transparent.

Glulam construction, product selection
Information about the main stages of construction of buildings from glued laminated timber will allow customers to adequately assess the qualifications of craftsmen and control the quality of work:- Project creation, approval technical nuances, drawing up estimates, determining the cost of work.
- Foundation laying. Due to the lightness of glued beams, a powerful foundation is not laid under it. If the area is not characterized increased level ground water, the height of the foundation will be 0.5-1 meter in height.
- Installation of the building box according to the project.
- Roofing works according to the project.
- Connecting the house to communication engineering networks and electrical system.
- Internal Finishing work according to the wishes of the customer.
First and most important point, which you should pay attention to when choosing a building material - its purpose.
Other options are also possible:
Glulam house for permanent residence
To create comfortable living conditions in a house made of glued laminated timber, where it is supposed 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 enough to create a comfortable temperature regime even on frosty days. An economy version of such a house is walls made of timber with a cross section of 140 mm with a heat resistance of 1 m ° C / W, insulated from the outside with foam or Ursa. On top of the insulation - decorative trim.
Glulam house for seasonal living
If you use the house during the first night frosts, then it is better to choose a material with a cross section of 160-180 mm. This thickness of the walls will withstand temperatures within 1-2 degrees below zero. If you leave the house before the first cold snaps come, then you can purchase a bar with a thickness of 140-150 mm. Additional insulation walls are not required.
You should also pay attention to the following points:
Tree origin
If a tree for production is brought from the northern regions, then it will be much better than wood from the southern regions. The cheapest, and therefore low-grade, wood from the marshy area is considered.
Wood type
The middle class is pine or spruce. Low grade - pine and spruce lamellas, laid mixed. You can distinguish pine from spruce by the number and size of knots. Pine has few of them, but they are larger.
Timber grade
The material must match specifications, where tolerances for the number of knots and the presence of defects are prescribed. If the seller says that the glued laminated timber complies with GOST, this does not guarantee the quality of the material at all, since GOST has too many tolerances.
Glued laminated timber grades sold:
Material Warranty:
If the manufacturer gives a guarantee on the material - this is a big plus. Immediately specify the moment about replacing the marriage, reporting the stock, the type of profile used, the possibility of cutting in the bowls of the wind pockets.
Glued beam length:
By the length of the proposed timber, you can find out what equipment is used for its production. If the manufacturer offers a beam 12 meters long, this means that modern equipment is used that is capable of producing such long lamellae. The old equipment is capable of producing timber up to a maximum of 6 meters in length. Pay attention to the length of the front boards. The longer they are, the more quality wood was used. Top grades- boards 1.5-2 meters on average, but such a beam is usually used in shipbuilding, lower grades of beam can be used for wall construction.

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 work with and very durable.
Glued cedar timber: pros and cons
Cedar wood has a number positive properties such as strength, ease of processing, interesting options textures and colors, pleasant aroma and emitted antibacterial volatile substances - phytoncides. Only in rare cases should wood of a different species be preferred instead.
Advantages of cedar profiled timber
Thanks to a special treatment, cedar wood acquires increased durability. Glued laminated timber from this breed is used in wooden housing construction.
Cedar is especially good in those structures and units where large drops in pressure and humidity modes are expected. In this regard, it competes with Scotch pine.
As you would expect, this type of wood has a beautiful wood texture and color. That is why cedar glued timber occupies a strong position among the 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 meters in height. Of all the heartwood species, cedar has the lightest and softest wood.
The core of the cedar is narrow and has a pinkish hue. The color contrasts with the yellowish-white broad sapwood.
Late wood is usually poorly developed and smoothly transitions into early wood. It is moderately resistant to cracking and rot, easily machined 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. In terms of strength, cedar timber surpasses some metals.
In Rus', cedar was often used for the construction of houses, log cabins and baths. Cedar resin can repel insects and destroy putrefactive bacteria.
If your house is built of cedar, the wood will provide you with a healthy deep sleep and a wholesome atmosphere in the house. this means that you will prevent many diseases of the nervous system.
properties of this coniferous tree in terms of health are unique. It is rich in essential oils and phytoncides.
When heated, the cedar gives off an exceptionally beneficial aroma of cedar balsam. Aroma Source - essential oils, which fight many types of pathogenic microbes.
A house made of cedar timber is favorable for human health for a long time. Cedar wood has a heterogeneous brownish-pinkish color.
