Which timber is better for construction. Choosing timber for building a house. Steel perforated fasteners for timber

Many of those who live in stuffy apartments, and when they go outside find themselves in gray smog and deafened by the noise of cars, want to change their living environment. Live in a wooden house, breathe clean air and enjoy the silence. And those who decide to do this often wonder how to choose timber to build a beautiful and reliable home for their family.

Today the construction market presents the most different types timber, different geometric parameters, profile, variety, production method. Choosing the best one is not an easy task, especially if the buyer’s financial capabilities are not unlimited.

From this article you will learn about all types of this material, their advantages and disadvantages, as well as how to save on your purchase without sacrificing quality.

Which timber is better

If you are not faced with the question of what to choose - timber or frame, if you have already decided what you will build wooden house, then the first thing you need to do is study the range of local construction markets and hypermarkets. As a rule, they offer three main types of timber: planed, profiled and glued.

Let's consider each type separately with all its disadvantages and advantages.

Planed timber

The material is obtained by cutting a log, during which a product with a rectangular or square cross-section is obtained. Main competitive advantage planed timber before glued and profiled timber - low price. Compared to a log, it is easier to assemble into a log house, and compared to brick, it requires less effort and installation costs.

However, in addition to tangible advantages, this type of timber also has serious disadvantages that you need to be aware of and take into account if your goal is a strong, durable and warm home.

Planed timber is made from wood natural humidity.

It gradually decreases as the tree dries, and this can lead to the following unpleasant consequences:

• Deformation. You can buy a perfectly even, beautiful beam, but after a while amazing metamorphoses will begin to occur to it: it can bend or even turn out like a “helicopter”;
• Cracks. This is the most common defect that worsens not only appearance material, but also its performance properties;

• Rot, blue, mold. If raw timber is stored in improper conditions - in poorly ventilated areas or in stacks close to each other, such manifestations are inevitable;
• Shrinkage. When building a house with your own hands, it is important to remember that over time the timber will dry out and its geometric dimensions will decrease. As a result, the entire structure will shrink, which depends on the initial moisture content of the material and environmental conditions.

Please note. If we were talking only about the loss of a few centimeters in height, this trouble could not be paid attention to.
But as a result of shrinkage, window and door openings can be deformed, the outer and interior decoration walls
Therefore, the log house must be allowed to settle for several months, preferably under the roof, before continuing construction.

• Crevices. Conventional planed timber often suffers from inaccurate dimensions, so when building walls it is difficult to avoid gaps between the crowns. They also increase as the wood dries. They must be sealed: lay sealing materials between the crowns, caulk the walls to prevent the penetration of cold and moisture.

The planed timber itself is not distinguished by its ideal shape and surface, and when the described defects are applied, it is completely inferior in appearance to profiled and glued timber. Therefore, it needs additional external finishing.

Profiled timber

You can avoid some of the problems listed above if you purchase profiled timber. It differs from the planed one in the shape of the section: its front sides are smooth, and the workpieces are made of a tenon-groove or comb type.

Which timber profile to choose depends not so much on personal preferences as on the moisture content of the material.

• The tongue-and-groove connection involves the use of insulation laid between the crowns in the grooves. Even if the timber shrinks when drying, forming gaps, it will prevent ventilation.

• The protrusions of the “comb” profile fit each other very precisely and do not require the use of insulation. But if the moisture content of the wood changes, the comb parameters may change. Therefore, when choosing such a profile, you need to be sure that the timber is dry and will not shrink significantly.

For reference. The advantage is that the wood is dried until its moisture content reaches no more than 22%, otherwise the quality of processing will be low.
Therefore, it shrinks less than planed wood.

Many woodworking enterprises produce profiled timber to size, according to the customer’s design, immediately cutting into it “cups” for joints and corner joints. You no longer have to think about how to choose a groove in the timber - the log house is assembled like a children's construction set.

But this material, nevertheless, is not without such disadvantages as the appearance of cracks and shrinkage, which requires a technological break in construction.

Glued laminated timber

This type of timber has the best performance characteristics, but also the highest cost. Its main advantage is low humidity and, accordingly, the absence of all those negative aspects that arise during drying of the material and shrinkage of the finished log house. You can build a house from it in one season, without waiting for natural shrinkage.

You will learn about how laminated veneer lumber is produced from other articles in this resource. We note that the technology of its production allows us to obtain a high-quality product, practically devoid of the disadvantages of raw wood, but possessing all its useful natural qualities. In addition, it is impregnated against rotting and fire and does not require additional finishing.

As in the case of profiled timber, laminated timber can be made to order in accordance with the chosen house project. And some manufacturers offer ready-made kits, which come with assembly instructions.

Please note. Not long ago, a new product appeared on the market - D-shaped laminated veneer lumber, the convex front surface of which imitates a rounded log.

How to save money on timber construction

The budget deficit for building a house does not always allow you to choose expensive and quality materials. But, if you know how to choose the right timber - ordinary, not subjected to special treatment, and how to prepare it for work, you can save a lot and get a good-quality and beautiful structure. Our tips will help you with this.

So, what to look for when buying?

• Evenness of timber. Determined visually and practically. The product must be placed on a flat surface with all its edges in turn and make sure that it is not bent or twisted by a “propeller”.
• The distances between the annual rings, visible at the end of the beam, should be the same. If they narrow or widen on one side, this indicates that over time the beam will “lead” and it will bend.
• The surface of the wood must be uniform in color everywhere. A visually noticeable color contrast at the ends or side edges indicates the presence of layers with different internal tension, which will also lead to deformation.

It is much more difficult to determine the moisture content of the material. But even if you see that the timber is completely fresh, but good quality, you can independently bring it to the desired condition. True, this will take time.

Having your own warm and reliable home is the dream of many people. A house built of wood is not only warm and reliable, but also environmentally friendly. Modern technologies construction offer various options construction wooden houses. Perhaps the best thing is to build a house from timber.

The timber minimizes the unpredictability of wood behavior during operation, and is therefore optimal building material. The construction of timber houses is completed within one season, and the durability of these houses is at least 50 years. There are 4 types of timber used in the production of wooden houses: solid non-profiled, solid profiled, glued profiled and the so-called LVL timber (from the English LVL - Laminated Veneer Lumber).

Which one is better to use to get a house with the best price/quality ratio? Let's look at the pros and cons of each type.

Solid non-profiled

The beam is made from a single log, with a round edge cut off on four sides. For the construction of residential buildings, naturally drying 150x150 mm timber is usually used.

• low cost;
• availability at any sawmill, that is, by choosing the nearest one, the issue of delivery of building material is easily resolved.

• warping, shrinkage and cracking are the disadvantages of naturally dried wood;
• wood defects - internal rot, flying knots, pests, fungus, which appear after completion of construction;
• the need for additional finishing - it is not subject to finishing, therefore it needs additional finishing;
• the need for enhanced insulation of the seams - it does not have strict transverse dimensions and evenness of the cut, as a result - large gaps between the crowns;
• low manufacturability - initially not suitable for the construction of walls, so additional reinforcements have to be made load-bearing walls and corners of the house, which means extra labor and time.

The price of a solid non-profiled timber with natural humidity is about 9,500 rubles. per cubic meter Plus finishing costs, mandatory processing fire-retardant compounds and additional work.

Conclusion: not the best good material for building a house, but if you have the labor, patience, accuracy and attention to detail during construction, you can build a house from it, and for reasonable money.

Solid profiled

The timber is also made from a single log, only it is driven through special equipment, where it is given ideal geometric dimensions, a special lock profile is selected and, of course, planed to give it an aesthetic appearance.

• low probability of warping - industrial wood drying technology makes it possible to achieve 10-15% humidity in the final material with virtually no deformation consequences;
• does not require additional processing and finishing of the walls;
• high precision connections (no gaps);
• manufacturability - locking profiles greatly facilitate the construction process.

• all possible wood defects mentioned above;
• the need for additional time for shrinkage - after all, the existing possibility of shrinkage and warping of solid beams requires time for the finished walls to shrink.

The price for a solid profiled timber kiln-drying is on average 12,000 rubles. per cubic meter More expensive than non-profiled, but the final result is much higher in quality.

Conclusion: after treatment with fire-bioprotection, subject to construction technology, perhaps best choice in terms of price/quality ratio, however, you must be prepared to deal with possible “surprises” of solid timber.

Glued laminated timber

As the name implies, this type of timber is also calibrated and equipped with a locking profile. However, it is not made from a single log, but from separate blocks. They are glued together under pressure with a special glue.

• all the advantages of profiled timber;
• resistance to warping - thanks to combination various types wood when assembling blocks for one log, further deformation, cracking is absolutely excluded and shrinkage of the finished beams is practically eliminated;
• no need for additional time for shrinkage - a house built from laminated veneer lumber, does not shrink and is suitable for habitation almost immediately after completion of construction.

• high price;
• low environmental friendliness compared to solid timber - glue is a foreign material;
• somewhat disturbed natural circulation moisture inside the timber, due to the use of glue, moisture is not able to circulate between the layers, because of this, a slight disturbance of the microclimate inside the house is possible.

The price of laminated veneer lumber is on average 25,000 rubles. per cube - twice as expensive as a whole one. However, it should be noted that the cost of a project of wooden houses made of laminated veneer lumber is no different from similar projects of houses made of solid timber, and in the costs of the construction itself, the cost of the walls is approximately half of the entire construction budget. Consequently, the final house will not rise in price by much. In addition, when construction time is reduced, and when using laminated timber, as mentioned above, it is minimal, the cost of work also decreases.

Conclusion: if you have the opportunity to spend money on this expensive version of timber, then for the quick construction of a turnkey wooden house this is best option, otherwise, it’s probably better to stick with a solid profiled beam.

LVL timber

The manufacturing technology of LVL timber is reminiscent of the technology of laminated timber, only it is glued not from blocks, but from 3 mm veneer. Plywood is produced in almost the same way, only, unlike it, the wood of adjacent layers in LVL timber is located parallel to each other relative to the fibers. This allows you to process this type of timber in the same way as solid or laminated timber. When gluing, the density of the various layers is selected in such a way that the denser layers are located on the outside and the soft ones on the inside.

• all the advantages of profiled laminated veneer lumber, only elevated to the rank of absolute;
• increased strength and elasticity, as well as unlimited length, makes it possible to manufacture spans of any size;
• increased moisture, fire and bioresistance.

• highest price;
• lowest environmental friendliness.

The price for LVL timber is about 35,000 rubles/m 3. This price makes it unprofitable when building walls of houses made of timber, but since it makes it possible to increase spans without the use of support pillars and beams, in combination with other types of timber it significantly expands the possibilities when choosing a project.

Conclusion: It is not a rational material for the construction of walls, but it is quite suitable for auxiliary structures.

All conclusions are quite clearly shown in the final table:

Thus, what the house will be like is always decided by whoever will live in it. Materials for construction must be selected based on your needs and available funds. From the analysis we can conclude that the most preferable for building a house from timber are solid profiled and glued profiled beams, however, there is also a place for other types.

Like any other material, profiled timber has several types, each of which has a number of advantages and disadvantages. Types of profiled timber have long been discussed on forums and by builders. It is difficult to lean in favor of one of them, since the range of these products is large and many types began to be used not so long ago. They have not yet shown themselves, and it is unknown what a house made from such a product will look like in 30-40 years.

We have already talked about all of them. But not many people know that the concept of “profiled timber” hides a huge variety of types of this product.

All differences between types of profiled material can be divided according to the following characteristics:

1. Size of profiled link. It can have different lengths and cross-sections.
2. Profile view. Comb, double, Finnish, etc.
3. Structure of the material. From solid massif wood and glued profiled timber, warm.
4. Appearance. May have a straight face or a D-shaped face.
5. Dried or natural moisture.

All types of profiled timber must comply with GOST 8242-88. Let's take a closer look at these types.

Size of profiled timber

All such material comes in several sizes, which are specified in GOST. Of course, manufacturers meet the buyer halfway and can produce profiled lumber of individual sizes. But there are certain standards: 100x100, 100x150, 150x150, 150x200, 200x200. The main indicator is the thickness of 100, 150, 200 mm.

Let's consider each thickness separately.

Thickness 100 mm

This type of lumber cross-section is used to build lungs wooden structures. For example: bathhouse, gazebo, veranda. A thickness of 100 mm does not make it possible to build residential buildings from it. Although if you are building country house and you are going to use it only in the summer, this thickness is enough. In a cube of lumber of this thickness, usually: 100x150 - 11 pcs., 100x200 - 8 pcs. The profile of this type is usually two tenons - two grooves.

Thickness 150 mm

This cross-section of the product is suitable for the construction of a residential building, since it is already thicker than the 100x150 timber, but at the same time it is cheaper than the 200x200 section. In a cube of such lumber: 150x150 - 7.4 pcs., 150x200 - 5.5 pcs. In this type of profiled timber, a profile in the form of a comb is already used. This prevents houses made from such products from freezing.

Thickness 200 mm

Professionals for the construction of large residential buildings like to use this particular size of profiled product. This type has high wall resistance and is suitable for building cottages. The most common material is profiled lumber with a section of 200x150, 200x200 mm. In a cube of such goods: 200x150 - 5.5 pcs., 200x200 - 4 pcs. This type is more expensive, but in winter it exists flexible system discounts

The length of standard profiled lumber is 6 m. Manufacturing according to GOST standards is carried out by companies that are responsible for the quality of their goods. Houses made from profiled timber can have a very complex design, and the manufacturer meets the customer halfway by producing the material to individual sizes. The length is also made to suit the individual type of project.

Profile types

Profiled timber has the main difference from a simple one - it is a profile. The profile is cut on machines using special templates. Great value when choosing profiled lumber, it looks like a profile. The profile displayed on the market has a large assortment, but it also has its own standards. The profile can be:

1. Profile with one spike.
2. Profile with two spikes.
3. Profile with beveled chamfers.
4. Profile with a large number thorns - “comb”.
5. Finnish profile.

I would especially like to note the Finnish profile. It appeared on the Russian market quite recently. He did not come to us from Finland. It’s just that the quality of such lumber is great, as are the background houses. One large wide groove is made on the bottom of the workpiece, and on top there is a tenon formed by two parallel strips. The groove has a greater depth than that of a conventional profile. When connecting raw materials with a Finnish profile, one link becomes more tightly connected to another. The Finnish profile provides greater protection from wind and cold. Shrinkage with such a profile occurs more evenly and, if insulation is used, it is practically invisible.

Material structure

All such lumber is divided into types according to its structure:

1. Made from solid wood.
2. Glued profiled.
3. Warm timber.

Solid profiled timber is made from solid wood with a cross-section of 160-200, 200-200 mm. All four sides are processed on specialized machines. The result is a profiled material of the desired cross-section and profile type. Usually, varieties of coniferous trees are used in its production.

Glued profiled products are made not only from coniferous wood, but also from oak. The design of this material consists of boards - lamellas. They are glued together with a special glue, laying each lamella opposite to the cross-section of the fibers of the previous one. This makes this type of raw material more durable and makes it resistant to fire and rotting.

When producing glued products, boards undergo special selection, which makes it possible to improve its aesthetic properties.

I would especially like to dwell on such a new type of this timber as “Warm timber”.

Warm timber

A new product on the construction market that has appeared quite recently is warm lumber. Its structure resembles glued one, but has increased thermal insulation. The thickness of a building made of warm timber is 16 cm, it will be equal to a wall made of laminated laminated timber - 37 cm, and a rounded log - 47 cm. This timber was designed for construction and living in extremely harsh conditions. For example, in the North. Such a house will not be afraid of temperatures of -50 degrees. The cost of such material is several times less than glued material.

It is made in multilayers using layers of lamellas and extruded polystyrene foam. Gluing occurs under high pressure and only dry lamellas are used.

We think that this product will take its rightful place in wooden housing construction.

Appearance

This timber may differ in its appearance on the front side. There are types:

1. Straight outer side.
2. D – Shaped front side.

The straight outer side of profiled lumber is the standard option. By using this type, you will get smooth and straight external walls.

D – The shaped front side is used for Block House buildings. This type of timber is suitable for those who want to have an aesthetic house reminiscent of a Russian log hut. The rounded outer side of such a profiled beam will make it possible to create such a structure. At the same time interior walls will be smooth.

Material moisture

The profiled product is divided into two types according to the degree of moisture:

1. Profiled timber with natural humidity.
2. Dried timber.

Material with natural humidity will contain 20-25% moisture. This has a detrimental effect on the house. Buildings made from material with natural moisture will shrink by 10%, but the price for such profiled timber will be less.

Dried profiled timber is processed in special chambers. There it is dried to a moisture content of 8-12%. This material will not shrink much and will crack less. This makes it possible to move into the house immediately after construction. The shrinkage of such a house will be 3-5%. Such timber will cost more, but the difference will be equal. Since, after shrinking, the natural moisture timber will dry out and crack severely, in addition, additional caulking of the walls will be needed.

Throughout Europe, houses made from such timber are considered premium class houses, just as panel houses are considered economy class. What type of profiled timber you choose ultimately depends only on you.

Solid timber house, where it will be comfortable to relax or live permanently, is not only the beauty, comfort and charm of natural wood, but most of all warmth. It is not surprising that one of the main questions of those who decide to build their dream home is what thickness of timber to choose. After all, the costs of materials, the need for insulation and the efficiency of heat conservation in cold winters will depend on this. Well, let's find out.

Warmth in a home is a relative concept and depends on many factors. If you wish, you can heat almost any building, the only question is how much you will have to spend on it (time, money, fuel). If the walls give off too much heat to the street, in fact it turns out that you are mainly heating this very street. This will not happen only when the walls are thick enough, correctly calculated, processed and insulated.

What is the thickness of the timber?

Today, several types of timber are produced: solid, profiled and glued. The first is a log sawn on all sides and, in addition to low cost, cannot boast of many advantages. The width of the beams ranges from 150-220 millimeters. However, it should be noted that even the thickest solid beam will retain heat worse than a profiled one, since due to the absence of grooves and tenons, the inter-crown seams do not fit so tightly to each other and are blown out more strongly.

Profiled timber is much warmer, more practical and easier to assemble houses. It may have several tongues and grooves. The more of them, the better the beams adhere, the warmer and more reliable the wall becomes. The same can be said about glued profiled timber, which, among other things, is not susceptible to cracks. The width of the logs can be very different, but the most suitable sections for building houses are 100x100, 150x100, 150x150 and 200x200.

What determines the choice of timber thickness?

First of all, you should focus on the purpose of the building - will they live in it permanently or only during the summer season. For temporary use in the summer, the ability of the walls to retain heat is not so important, so a thickness of profiled timber of 100-150 millimeters is quite sufficient. If you plan to live in the house all year round, we recommend timber with a cross-section of 200x200 millimeters.

It is also important to take into account the climatic features of the region. The Moscow region is located in middle lane, winters here are not as severe as in the north or in Siberia, but not warm either. The value of heat transfer resistance in reference books is designated as 3.0.

There is a formula by which you can calculate the required wall thickness in a house depending on the climate zone. Heat transfer resistance value in climatic zone multiplied by the thermal conductivity of the material (for wood it is 0.15). That is, 3.0*0.15=0.45 meters. In other words, 450 millimeters. The only problem is that timber of this size is not produced.

What if with insulation?

We were faced with a problem: according to the formulas and SNiPs, the thickness of the wall wooden house in the Moscow region it should be 450 millimeters, but such timber cannot be found. The only way left is to insulate yourself. It is believed that 50 mm of insulation = 150 mm of ordinary timber. Accordingly, suitable options:

• timber 150 mm thick + 100 mm insulation (similar to 300 mm timber);
• beam 200 mm thick + 50 mm insulation.

In the first case, the output is exactly the 450 millimeters desired by SNiP. In the second - 350 mm, however, as practice shows, they are absolutely sufficient to retain heat if profiled timber is used. After all, its degree of wind blowability is much lower, warm air does not leave the house through cracks, and cold weather has fewer opportunities to get inside.

Conclusion

Where and for what purpose you build a house, it will be warmer and more comfortable if you choose profiled timber. For temporary residence, a section of 100x150 or 150x150 is sufficient. For permanent residence in the Moscow region, profiled timber 150x150 is suitable, provided that 100 mm of insulation is installed, or profiled timber 200x200 is suitable, provided that 50 mm of insulation is installed.

Venga company specialists are always ready to advise you on any issues related to the construction of houses made of timber, give their recommendations and bring them to life!

Wood is one of the the best materials for the construction of houses, baths, saunas. However, in order for lumber to fully reveal its advantages, you should carefully study its characteristics and make right choice. The source material is an ordinary round log. What kind of timber is there? This lumber most often has a rectangular shape (less often - arbitrary) with a section thickness of 50-400 mm. IN modern construction it exists in several forms.

All types of timber on the building materials market

• Solid (non-profiled) timber

Externally, it is a log, sawn on 4 sides, more than 50 mm wide. This material is the most popular in construction and has a multifunctional value. Wall structures are erected from ordinary timber, rafter system roofs, partitions between floors of the house. It may well be replaced wooden block. Considering what types of timber there are, it should be noted that the low cost of logs is explained by the ease of their processing. This means that the material requires additional protection.

The cross-section of the material can be from 150 to 220 mm, the humidity is natural. The diameter of the material is selected depending on the type of object being built: in the construction of houses for permanent residence, lumber with a diameter of 200-220 mm is used, for a sauna, bathhouse or cottage - 150-220 mm.

The ease of installation and low cost of non-profiled timber makes it one of the most popular in the construction industry.

Advantages of houses built from solid (non-profiled) timber

1. Availability. Today this is one of the most popular offers. Unprofiled lumber can be purchased at any construction market. At the same time, after placing an order, you do not have to wait for a long time for delivery. The ease of preparing the material explains its ubiquity.
2. Low cost. Considering the fact that the natural importance of the material is preserved, the process of its preparation is simplified as much as possible, which has a positive effect on the cost of the timber.
3. Convenience and high speed of house assembly. No specialized equipment is needed to lay non-profiled timber. Installation work Carpenters can carry out 3-4 grades. Moreover, the assembly of a 6*6 m house is carried out in less than one week.

Disadvantages of houses built from solid timber

1. The need for finishing works or planing. The best option is cladding with a block house or forcing. In addition, you will need to trim excess jute after natural drying and shrinkage at home.
2. Non-compliance of non-profiled timber with GOST requirements (relates to the evenness of the cut and the size of the cross section). As a result, differences in the placement of crowns can reach 5 mm, and the seams can be at different heights. The only way to minimize such problems is to purchase solid timber high quality. In this case, the cost of solid material is as close as possible to the price of profiled timber.
3. Fungal infection. During the harvesting process, the material is not subjected to special drying, which significantly increases the risk of wood being damaged by fungus. Today, more than 15% of non-profiled (solid) timber has this drawback. In this case, it is necessary to carry out antiseptic treatment, as a result of which the fungus is destroyed and its reappearance is prevented. However, this event significantly increases the cost of production.
4. Imperfect appearance. Compared to its profiled counterpart, solid timber has a less attractive appearance. After planing the walls, the seams and insulation between the crowns may become noticeable.
5. Corner connections are made without overhangs.
6. Cracking of the material. As a result of shrinkage and shrinkage of the walls, noticeable cracks appear that spoil the aesthetics of the house. The solution to the problem is the exterior decoration of the building.
7. Blowability of inter-crown seams. If there are no tongues and grooves when assembling the walls, the house will retain heat less well.

This type of material has clearly defined parameters. It is presented in the form of a planting bowl with tongues and grooves; there are also vertical cuts, which greatly simplifies installation. In production, the log is cut with an accuracy of 1 mm.

The use of profiled timber in the construction of houses makes it possible to obtain a structure without cracks, which means that the risk of moisture getting inside the structure and wood rotting is reduced.

In addition, a house made from profiled lumber is very warm, which minimizes the use of insulation. It is worth noting the unsurpassed appearance. Such timber has smooth and even walls and does not require finishing. But profiled timber also has weak points. It must be properly dried, otherwise there is a risk that the house will “lead” over time. Its humidity is about 10%. Drying lumber requires significant areas, and the maintenance of such areas affects the cost of the final product.

Advantages of profiled timber

1. Unsurpassed appearance. The use of this material allows you to build houses with ideal smooth walls. This eliminates the need for additional exterior finishing buildings.
2. Connections are made with projections (into the bowl). Since the connections are created in the factory, they are smooth and high-strength, which ensures high reliability of the structure and uniform shrinkage during operation.
3. There are tighter connections between the crowns and in the corners, which significantly increases the thermal characteristics of the structure and ensures minimal ventilation.
4. There is no need to trim the jute and there is no need to caulk the house. The only exceptions may be end and corner connections.

1. The need for a technological break during the construction of a house. It is caused by the fact that the material must dry. After assembling the structure, the house should “stand” for 10-12 months, after which you can proceed to finishing work.

Cracking of the material. Profiled lumber, like other types of timber, is made from solid wood, which inevitably entails the appearance of cracks.​

• Glued laminated timber

Today they are most popular. This material is made from pine, larch, spruce or cedar. The log is sawn into boards, after which they are dried. Next, the lamellas are treated with protective compounds and glued together. One beam can have from 2 to 5 lamellas. The shape of the elements is cut out with maximum precision. The result is a high-quality, durable material with less than 1% shrinkage.

Advantages:

1. The material is not subject to cracking.
2. There is no need for finishing or additional processing.
3. Minimal shrinkage and the risk that the structure will “lead.”
4. The optimal moisture content of laminated timber will eliminate the risk of rotting and damage to the wood by microorganisms.
5. Due to its high strength, this lumber can be used in highly complex projects.

Flaws:

1. Relatively high cost (2-3 times more expensive than non-profiled lumber).
2. The use of glue in production reduces the degree of its environmental friendliness in comparison with logs or profiled timber.
3. The presence of glue impairs air exchange and moisture circulation.

Glued laminated timber is the best choice for “quick” construction. On a ready-made foundation, you can build a house in just 5-6 weeks.
