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 geometric shapes, lack 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.

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.

Video. Construction from laminated veneer lumber:
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.
This is a very precise, high-tech process. He does not tolerate inattention even to the most to the smallest details. Having decided to start producing laminated veneer lumber, the Siberian Wooden Houses company began with the main thing - searching for good wood.
During our work, we have thoroughly studied the properties of different types of wood. And therefore we decided to give preference to the best pine in the world, growing in the central regions of Russia. And the workshops themselves were located in Nizhny Novgorod, which is very convenient, since the timber does not tolerate long transportation, it can get wet or crack during transportation. The same measure allowed us to reduce the time period from cutting down a tree to obtaining the final result - finished timber.
Along with wood from the central regions, we also use more expensive Siberian wood, depending on the preferences of our clients.
After conducting a thorough analysis of existing proposals in the segment of equipment for the production of “glulem”, we settled on production lines of Western European production. In particular, our company purchased a number of high-quality German-made machines from one of the world leaders in the woodworking equipment market - the Weinig company. Therefore, we not only do not hide, but are also proud of the composition of our production “park”.
When gluing timber, adhesives from one of the world leaders in the chemical industry - AkzoNobel, based on melamine, which have high heat, water and weather resistance, are used. All adhesives used have quality and sanitary certificates.
But at the same time, production times are increasing. Depending on the project, the production of laminated veneer lumber for the construction of one house, in compliance with all necessary conditions, takes from a month to two. For some, this period may seem too long. In fact, high-quality execution of all production processes not only ensures that the laminated timber preserves all performance characteristics in the long term, but also significantly speeds up the assembly of the house itself. Unlike building a house from rounded logs, carefully fitted parts from laminated veneer lumber are assembled on site literally like a construction kit, which simplifies the process of building the building as much as possible. As a result, the customer does not need to overpay for excess material and extra work construction team.
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”.
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.
