When starting to build a house made of profiled timber, special attention attention should be paid to the appearance of his profile. Today there are at least four of them, each of which is characterized by its inherent advantages and disadvantages. All this must be taken into account in order to end up with a solid wooden house.
In this article we will look at timber profiles, let us note their positive and negative aspects, which will allow, based on the information received, to have a holistic idea of what direction to move in when implementing a plan for the construction of a residential building, and indeed any other wooden buildings of the most for various purposes.
Wooden house construction has a centuries-old technological history. Even our grandfathers could cut down a house with one ax - warm and first-class. However, life does not stand still: change manual processing logs came machines - mechanization. This significantly simplified and accelerated the construction of wooden houses in Belarus, Russia and a number of other, mainly northern, countries.
As a result of technological improvements, a variety of wood building materials appeared on the market, but the most popular were rounded log and, of course, profiled timber.
Engineers paid great attention to the method of connecting the crowns. First of all, it was important to ensure that the walls were not blown through. Old ways connections were not suitable here, so new ones were created, which during testing received excellent characteristics and approval from specialists. These are the very timber profiles we are talking about.
What is a timber profile
The beam profile can be compared to a tread car tire. Essentially, this is a pattern that appears on the timber through machine processing. As with car tires, so with profiled timber, special importance is attached to the degree of adhesion of two surfaces, only in the first case - between rubber and the road surface, and in the other - between a crown and a crown.
The profile is created on specialized equipment. Process includes the following steps: wooden blank(for example, a beam 210x160 mm) is “driven” into the machine, and at the output a profiled beam (size 200x150 mm) is obtained, which already has a pattern corresponding to the type of profile. At the time of technological processing, the timber is ground.
As we noted above, timber profiles are different. They are distinguished by the number of grooves and tenons; some form a comb of three or four grooves on the surface of the timber. Thanks to this, the production of a rigid house structure is achieved. The convenience is that there is no need to once again measure the diagonals of the house, since high-precision equipment ensures the production of building materials with the appropriate parameters.
Types of timber profiles
Profiled timber should be divided into two types:
— with the possibility of laying along the crown of insulation;
- without such an opportunity.
Note that there is no consensus on which type of profile is better. Manufacturers praise their products over and over again, but here objective information is more useful, which will allow you to form the most reliable opinion about what type of profile can and should be given preference in a given situation.
In Belarus there is no document that would clearly regulate or establish certain standards for timber profiles. But in this matter you can rely on the experience of Finland. In this country profile beam without the possibility of laying insulation, as well as with a small/medium height comb, it is intended only for the construction of non-residential buildings, for example, outbuildings.
So, today the following are distinguished: types of timber profiles:
- profile with one spike;
—profile with two spikes;
—profile with beveled chamfers;
— comb profile - with three to four spikes;
—Finnish profile.
Timber profile with one tenon
This is the simplest type of profiled timber. This building material is used for very economical construction. As a rule, it is used in the construction of summer houses and outbuildings.
The advantage of single-tenon timber is its relatively low price. Simple technological processing of workpieces makes it possible to obtain beams with a tenon on one side and a groove on the other. The connection principle is not complicated: the tenon is inserted into the groove, which ensures the connection of the crowns.
The disadvantage of such timber is that it is not recommended for use in regions with a long winter-cold period of the year. The fit of this beam, as practice shows, is not sufficient, so cold bridges can form. In addition, when a wooden structure shrinks/shrinks, cracks more often form between the crowns, which requires their subsequent caulking, and this may not have the best effect on the appearance of the house or structure.
Thus, the use of profiled timber with one tenon is possible, but only if the technology for its laying and installation is strictly followed.
Beam profile with two tenons
It can be used for the construction of wooden houses in Belarus, but on the condition that insulation and sealant are laid between the crowns, and the thickness of the timber is at least 150 mm.
Thanks to double studding cold air does not penetrate into the inter-crown space deeply enough to worry about freezing of the walls. In addition, beams of this design have a better fit.
At the time of drying, they can twist and bend - which is natural for wood, but in this case it is necessary to use dowels, all kinds of inter-crown connectors, and the optimal principle of the lock itself must be chosen. This is the only way to stop negative consequences or minimize them during drying wooden structure.
Some manufacturers of profiled timber lay insulation along its entire length in the form of a foam seal with a diameter of 5-8 mm, which reduces thermal conductivity by 35-40 percent, therefore, inside a house built from of this type building materials, it will be warm.
Beveled timber profile
Profiled timber (with different amounts tenons and grooves) may have chamfered. This is done not only for aesthetic reasons, wanting to highlight each beam, emphasizing the naturalness of the building material. There are two more reasons why they chamfer.
One of the main ones is preventing water from flowing into the inter-crown space. Water has a negative effect on the groove and tenon: when they swell, they expand, which leads to their deformation and the appearance of cracks. In addition, the missing chamfer allows for more efficient caulking of the walls.
As a rule, the chamfer is removed from the upper edge of the beam, because if this is done from the lower edge, then the passage will be “open” for water into the inter-crown space. Not only the building material itself will suffer, but also the insulation. Everything will quickly turn to rot. Note that standard sizes There is no chamfer; each manufacturer of profiled timber decides for himself what the amount of removal should be.
German profile timber (comb)
Every specialist who is involved in the construction of wooden houses will say that profiled timber with a “comb” pattern is optimal solution in the choice of building materials.
The comb is created by selecting grooves and tenons. There can be three or four of them, which provides the maximum possible protection against cold penetration into the house. When the tenon gets into the groove, there are no conditions left for air to overcome the “obstacles”, therefore, such an inter-crown connection is considered one of the most reliable and warm.
In some regions this type of profile is called “German”. It was developed with the goal of getting rid of the use of insulation and sealants, which put “price pressure” on building materials. Indeed, this approach made it possible to reduce the cost of comb-profiled timber by as much as 15 percent, which is considerable, considering the purchased volumes of building materials necessary for the construction of a residential building in Belarus.
This profile also has one drawback: the presence of a large number of tenons and grooves complicates the work of connecting the beams to each other, because to do this you need to not only bring the beam to the wall, but also aim it with precision so that it “sits” in its place. Often, the use of comb-profiled beams during the rainy period leads to an increase in their humidity, which also complicates the process of “putting” the beam on the beam. And yet, the speed of building a house does not depend on the type of profile, because higher value has the fact of who exactly performs construction work.
Thus, if you build a house or cottage from comb-profiled timber, you will get a reliable and very warm structure that will delight its owners with its beauty and reliability for many years.
Finnish profile timber
The Finnish profile appeared on the Belarusian market relatively recently. It is noteworthy that the technology for its creation was not developed in Finland. Rather, the name of the profile was given by analogy with the high quality that Finnish houses in Belarus.
This type profile is the following figure: on the bottom of the log, select a groove of such a width that there are spikes of sufficient height (at least 1 cm) on the sides of the beam. Thanks to this, the support area of the beam increases significantly, which ensures a better connection of one crown to another.
It has been proven in practice that the Finnish profile reliably protects the house from winds and frost. In addition, a house made of profiled timber with a Finnish profile gives more uniform shrinkage. In cases where insulation is used, it will not be visible at all, which increases the aesthetic appeal of the house.
Swedish timber profile
The House Factory company does not use the Swedish profile in the production and construction of houses.
Profiled timber from "House Factory"
Company "House Factory" offers clients best samples profiled beams: with three and four tenons and beveled chamfers. Such products meet the requirements for building a truly warm and reliable home. Production technology, which is used at the enterprise, meets the requirements of our time.
Multi-tenon beam has a number of advantages.
—Firstly, the construction of walls does not require their insulation using insulation or sealing tape. A very high-quality connection leaves no hope for the cold to penetrate into the house. Thanks to this, significant money is saved for home customers.
—Secondly, such timber makes it possible to carry out construction work at an accelerated pace. The work of construction specialists can be compared to folding a Lego set. The absence of temporary “delay” also has a positive effect on the balance of the family budget.
—Thirdly, raw materials are used only high quality- this is pine and spruce wood, which has a high fiber density, which provides the material with minimal heat loss, therefore, the walls of a house made of profiled timber will never freeze, which is very important for the northern regions of Belarus.
In addition, the production cycle implemented in the workshops "Factory houses" provides for chamfering. We talked about the features of this type of bursa above and there is no point in repeating it, but we note that this principle of increasing performance properties is not applied by all industry enterprises.
Therefore, the company "House Factory" produces the two most popular types of profiled timber: German and Finnish, which have a lot of advantages and a minimum of disadvantages. The latter, by the way, can be avoided if you follow the construction technology wooden house. The specialists will take care of this "Factory houses". We work within the framework of high requirements, so we manage to carry out the tasks assigned to them at the highest possible quality and organizational levels.
A trend has developed in the market when wooden house construction began to grow in demand. Against this background, various companies and firms have appeared and this seems to be good, however, some in their work are focused on quality and modern technologies, while others focus on the opportunity to make quick money at the expense of quality.
The former purchase expensive equipment, conduct professional training for workers, introduce foreign technologies and monitor the quality of raw materials, while others are looking for opportunities to produce timber with at the lowest cost. This attitude affects the consumer properties of wooden houses, which naturally affects the image of wooden house construction as such.
You should only trust companies that have been operating for many years and are ready to guarantee the construction of wooden houses in Belarus in accordance with the high requirements of customers.
Thus, turning to "House Factory" you can protect yourself from cooperation with non-professionals, ensure reasonable investment cash in residential real estate, have positive construction experience
For construction country cottages are used various types timber. But among them, profiled is considered one of the most practical timber with comb profile, which performed best in Siberian frost conditions.
His design features provide a number of key parameters.
High thermal insulation
Tight, warm seams prevent the walls from being blown through, which allows for 20-30% better heat retention. The shape of the comb prevents moisture from flowing in. And after the house shrinks, the seams become airtight. Thus, the walls of the house become monolithic structures.
High connection rigidity
The entire structure is a strong connection. When dry, the timber is not subject to cracking, and its deformation is impossible. Moreover, it does not require a sealant.
Speed and ease of installation
Work with profiled timber with a comb profile is characterized by simple construction of walls.
Does not require additional finishing
The timber does not require sharpening, sanding, finishing with clapboard or siding. Immediately after assembly, the house takes on a noble appearance natural wood. The only thing is that the outside can be coated with an anti-corrosion compound.
Environmental friendliness
Profiled timber does not contain chemical additives or glue. The tree provides natural ventilation, constant humidity in the house. In addition, the material is able to absorb odors, creating a cozy microclimate in the rooms.
Typical sizes
The standard comb height is 9-10 mm. Less commonly used is a material in which the groove depth in the inter-crown connection is 15 mm.
How millimeters save thousands
Perhaps the price is the only drawback of the material. Construction can cost 1.5-2 times more than using regular sawn timber natural humidity. Despite this, experienced builders are confident that profile timber, on the contrary, allows them to reduce costs.
Firstly, there is no need for external facade finishing Houses.
Secondly, it gives minimal shrinkage (within 3%). And for profiled timber with a comb profile, this figure is even lower (up to 1%), and is comparable to the technological indicators of laminated veneer lumber.
Thirdly, if the house is designed for year-round accommodation, That castle type connection simplifies the work on insulating the building. Warm seams do not require caulking, make the house much warmer and reduce the cost of heating rooms.
You can argue for a long time about the advantages of one profile or another, as well as make comparisons, but any of these materials has its advantages and disadvantages.
How to choose timber for building a house
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 on construction market the most different types timber, differing in geometric parameters, profile, grade, production method. Choosing the best one is not an easy task, especially if the buyer’s financial capabilities are not unlimited.
Beam is the most popular building material made of wood
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 is obtained that has a rectangular or square section. 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 costs to build a foundation for a house made of timber.
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 with natural moisture.
It gradually decreases as the tree dries, and this can lead to the following unpleasant consequences:
- Deformation. You can buy a perfectly smooth, beautiful timber, but after a while amazing metamorphoses will begin to happen 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;
The photo clearly shows deep cracks - the result of wood shrinkage
- 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.
Log house made of planed timber with insulated seams
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 with the formation of gaps when drying, the insulation for the timber will prevent blowing.
- 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 of profiled timber is that before milling on a four-sided machine, 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 connections. 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 is distinguished by the best performance characteristics, but also high cost. Its main advantage is low humidity and, accordingly, the absence of all those negative aspects, which occur 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.
Such timber consists of well-dried and defect-free lamellas glued together.
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 flat surface alternately with all sides and make sure that it is not bent or twisted by the “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 stresses, 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.
Place the purchased material in stacks, placing even veins under each layer every 1-1.5 meters. Leave a distance of 2-3 cm between the beams in a row so that they are blown with air from all sides. Also place veins on top and cover the top of the stack.
Storing timber for drying
To avoid drying too quickly, which is accompanied by the appearance of cracks, position the timber so that the sun's rays are not directed at the ends. And whiten the ends themselves.
Construction can begin when the moisture content of the material is less than 20%. In this case, you can count on uniform shrinkage, no deep cracks. And it will be easier to work with him.

Conclusion
It is difficult to say which type of timber is better - glued, profiled or regular. Everyone has their own requirements for materials. Adherents of everything natural may not like the fact that laminated veneer lumber contains foreign polymer substances. And for those who don’t want to wait a long time for a housewarming party, planed or profiled timber is not suitable.
In this article you will see additional information on this topic, which will help you make a balanced and only correct choice in your case.
The profile of the timber is determined by the manufacturer himself, taking into account the capabilities of his production. The level of sharpening equipment allows you to produce a profile various types. The range of profiles is actually not large, but it is being improved every month. Many types of profiles came to us from Europe, where they have already proven themselves well. Manufacturers understand that the easiest to assemble and also the most popular profile is the “comb” profile. This type of profile began to be produced not only in large industries, but even in artisanal conditions.
Many factories produce the following main types of profiles:
- A type of timber with two tenons and grooves.
- A type of timber with more than three tenons - grooves - “comb” or “German”.
- Finnish profile.
The more ridges such a profile has, the better its thermal performance. But not many people know that if you deviate from the dimensions, the “comb” profile will crack when drying or glued along the lamellas. Even compliance complete technology will not give full guarantees, since when changing equipment or readjusting it, you can miss the size and an error of even half a millimeter will give such a disastrous result.
You may ask the question, why was this type of timber even invented? Why was it necessary to construct such complex processing profile? The designers based their idea on reducing the interventive distance to a minimum and completely eliminating additional insulation. The shape of such a profile should have made it possible during construction to provide a more dense connection of the beams with each other. This means that subsequently, such walls should not only become the warmest, but also completely prevent the entry of moisture and wind into the house. In fact, this did not happen, hence the negative reviews about such buildings.
Pros and cons of the comb profile
The advantages of such profiled timber with the “Comb” profile declared by the manufacturers are:
- More rigid connection between each other.
- Increased thermal insulation.
- The comb, due to its design, does not allow rain and wind to penetrate.
- As the house dries and shrinks, the seams with a “comb” appearance adhere even more tightly and become practically airtight.
- Houses made from profiled “comb” timber do not require additional sanding or planing.
- A structure made from such material can be immediately coated with impregnations and painted.
- It is faster to build from such material.
The manufacturer tells us only about the advantages of its product. This is justified by the fact that any material for him is just a commodity that needs to be sold profitably. But profiled timber “comb” also has many negative sides.
Production of the “Comb” profile
Technology of this profile requires additional equipment and the presence of special attachments for the frieze. Moreover, such a profile cannot be made on any milling machine.
The technology for its manufacture came to us from the Germans. That is why this type of timber is also called German. It is made from ordinary material by milling. After the structure is ready, it must be cleaned of sawdust and dust and treated with special antiseptics. This is done to prevent it from rotting and becoming infected with fungi. Since such a profile will be difficult to process in the future.
Is there a difference between timber from the manufacturer?
Manufacturer differs from manufacturer. We have already said that the manufacture of a “comb” profile requires precision and special adherence to all the rules and stages of its manufacture. And this can only be accomplished by a manufacturer that values its reputation. When purchasing timber of this profile, pay attention to how many years this manufacturer has been working on the market, read customer reviews. Many craftsmen have learned to make the “comb” profile in handicraft industries. They do not follow technology and are not responsible for the quality of their products. The price from such sellers will be lower, but you will not receive any guarantees. In the end, you will most likely just throw away money.
Profiled “comb” timber with a large cross-section is very difficult to dry. Buy a pocket moisture meter and don't trust what the salesman says. He will measure the moisture level of the material brought to you before paying the supplier.
High-quality materials of this profile must not only be properly made, but also stored in appropriate conditions. Fly-by-night companies cannot afford such an expensive pleasure. And this will certainly affect the quality of the product.
By purchasing profiled “comb” timber from the manufacturer, you can not only count on a guarantee, but also not spend your money in vain.
Price for profiled timber “comb”
The cost of profiled “comb” timber today depends not only on the manufacturer, but also on the time of year and the price of wood, gasoline and labor. Great value The grade and type of wood used also plays a role here.
The average price in Russia for profiled timber “comb”: natural moisture - from 7,500 thousand rubles per cubic meter, dry - from 11,000.
They say how many people there are, so many opinions. This can rightly be attributed to reviews of the profiled “comb” timber.
It is difficult to argue and agree with these reviews, since this building material has not yet been tested and it takes time to draw any conclusions. But one should not take the European experience as an example, since the climate and ecology in Russia are completely different.
If we talk about choosing timber, which profile is better? Even a highly qualified specialist cannot answer this question unequivocally. First, you need to set the goals for which this element is being purchased and determine whether the profile of the timber will justify the choice made. If an error is made in the calculations, then there is a possibility that all previously carried out construction work will have to be redone.
By choosing high-quality building materials, you ensure long-term and high-quality operation of the house.
Types of profiled timber
Today there are a lot of options for profiled timber. What exactly the profile will be is determined by the manufacturer himself based on the capabilities own production. At the same time, there are not only domestic but also foreign options on the construction market.
According to the type of profile, timber can be divided into the following types:
Bars with spikes provide better and tighter grip.
- element with two grooves and the same number of tenons;
- an element with tenons and grooves, the number of which exceeds 3;
- Finnish profile.
All presented types are designed to provide greater thermal conductivity to the room and ensure a stable temperature in it. The tight connection of the beams with each other will also significantly reduce the cost of insulating the room.
Bars with spikes and grooves of the “comb” type represent a log, on the top and lower parts which contains a whole row of teeth. They provide better adhesion of the beams to each other, however, this fastening technology also has disadvantages. One of them is the complexity of carrying out installation work, because all the blocks must fit very tightly to each other. In addition, when the temperature changes, the wood becomes deformed and loses its original appearance. Fastening such beams together will be extremely problematic.
In this case, it will be possible to hammer in the beams using a sledgehammer, but it will be impossible to guarantee that cracks and chips will not appear on the wood. However, if the construction work carried out using the “comb” profile is nevertheless crowned with success, you can safely expect that the building will stand for quite a long time.
The so-called Finnish profile is faster from an installation point of view. There are only two connecting pins on each side, but even they can ensure a reliable and high-quality fit of the elements. In addition, thanks to special processing, the “Finnish profile” practically does not shrink and is not affected by temperature changes. This profile should definitely be chosen when building baths and saunas, because such a structure can last at least 20 years! However, as additional protection, the outer surface of the walls can be treated with a special varnish that prevents damage to the wood by small rodents.
Where to buy timber?
When planning the construction of a bathhouse, many want to save money by purchasing timber second-hand. This option will be several times cheaper than the factory one. However, will it last as long? Today, getting an unambiguous answer to this question is quite problematic. Only one thing is clear: regardless of the price, preference should be given to the factory version.
The thing is that most manufacturers provide warranties for many of their products, including beams. In the event that a material, operated in accordance with all standards, suddenly begins to crack and dry out, the consumer has the right to demand compensation or replace the entire delivered batch. A private person never provides such obligations under any circumstances.
In addition, the timber made in a makeshift way and having, at first glance, an ideal appearance, may not completely correspond to the declared technology.
And this fact will certainly affect the durability of the structure being built.
The raw material that is selected by the craftsman for production also plays an important role. If the manufacturing is carried out by a specialized enterprise, which plays an important role in its reputation, it selects exclusively high-quality raw materials that can serve the buyer for many years.
What will a private workshop use to produce profiled timber? It may be a well-decorated material, but it is completely unsuitable for use.
In addition, the carving applied to wood in a factory will have a clear and perfectly even pattern, repeated on each new product. Joining such elements is not difficult, which cannot be said about products made in a different way. The thread there, at least slightly, will differ, so connecting the elements together will be much more difficult.
