Any person dreams of living in comfortable conditions, the list of which includes a comfortable house, a pleasant and stable microclimate. Particular attention in such buildings is paid to high-quality insulation of the building. This stage is of great importance for the owners of log houses. How to properly dig a house so that you do not have to redo the erected creation in the future? A large number of private developers are trying to find the answer to this question.

Caulking a house from a bar is necessary for its insulation.

Having searched for a sufficient amount of material on this topic, you can find the statement that it is not necessary to use a similar method of insulating a building. Such arguments are argued by the following fact: before use, wood undergoes special processing, and the buildings erected from it should not shrink. This means that the appearance of cracks in buildings from a bar is excluded.

Despite this point of view, profiled beams occupy a central place in the ranking of building materials, and they also have an attractive price. Any timber is a wooden base with all its inherent characteristics. It can dry out if a material of a natural degree of moisture is selected for the construction.

Despite the fact that insulation can be laid in the gap between the logs, this will not relieve the wood from shrinkage, as a result of which its dimensions will noticeably decrease, and the gaps will become more noticeable. If you do not dig the log house, the warmed air from the room will end up on the street. Timely work carried out will eliminate the occurrence of dampness on the walls and surface decay.

Necessary tools for work

Do I need to caulk a house from a bar? Yes, it is necessary to do this, because a correctly carried out process will eliminate the cracks in the space between the timber and at the points of connection of the crowns, the heat will be stored in the room, drafts and icing will not appear there.

The material used for caulking must meet certain requirements. In terms of quality indicators, it should be similar to a tree and have a clean, in terms of ecology, foundation. Such raw materials are not characterized by a change in external data under the influence of high humidity and temperature indicators. Air should not pass through it, at the same time, the source must absorb moisture from the surrounding air and get rid of it in a timely manner. There should be no rot or pests in such material. An important indicator of such a source will be the preservation of valuable indicators for the longest possible time.

Among the materials used to insulate the seams of houses, for a long time they used marsh moss-sphagnum, linseed tow, hemp hemp. Modern achievements in the construction field have provided a new material for mass use, jute. One of the best options is marsh moss, which reliably protects the walls of the building from putrefactive processes, fungal manifestations.

As a result, buildings last much longer. Moss is able to actively absorb moisture, and if the need arises, it saturates the wood with it. Its base is excellent for air permeability and has antiseptic properties. Moss is a flawless caulking material. However, it is rather difficult to decorate the seams in a log house with it. And it is not easy to collect such raw materials in the required volume.

Linseed tow and hemp hemp are also used for caulking at home, but their quality indicators are much lower than the considered option. These options are classified as industrial waste, have a similar structure, hemp has thicker and stronger fibers. The lack of such materials will be the remnant in the form of a fire, it begins to crumble over time, and there is a need for repeated work.

Jute is an imported product; it has been used in construction not so long ago. Any house will be reliably caulked with this type of materials, providing it with a special strength, hygroscopicity, and excellent air conduction. Jute is not capable of rotting, becoming moldy, its strong base does not allow birds to pull fibers out of crevices, which is often observed when using tow and hemp.

Jute is sold in ribbons and fibers. The first form creates comfortable conditions for defining them in the space between the crowns in the frame. Pure jute fiber helps in creating an even compactor. But such material will have a fairly high price. To make it cheaper, flax becomes an integral component of jute, which does not have the best effect on its quality indicators.

Technological features of caulking buildings

How to caulk a house from a bar? To study this issue, you need to familiarize yourself with the features of the procedure. The process of filling holes in a building is not as easy as it sounds. The beams must be clearly and stably fixed and reinforced. To connect the crowns of the house, you need to use a layer of insulating material, the thickness of which is equal to 5 mm. A log house built from a material of a natural degree of moisture allows increasing these indicators to 10-15 cm. When constructing a building from a profiled bar, an insulating layer is placed in the space of spikes and grooves.

It happens that the timber connection resembles a combination in a log house, the lower part of them has a relief plane, and the opposite is a concave shape. In this case, the space between the logs is filled with insulating material, its edges must hang 4-5 cm from the outside. A timber structure that does not allow material to be fixed in the gap between the beams, the gaps from the inside and from the outside are insulated one at a time.

Traditionally, the log house is caulked, starting from the top, gradually moving down. The ideal way out of this situation would be to attract assistants, it is good if they start working together, that is, each of the walls is occupied by workers. In this case, you do not have to worry about the skew of the building, on the contrary, its height may increase slightly, up to 15 cm.To carry out this process in a coordinated and organized manner, they use for work:

• caulk;
• an ordinary knife;
• spatulas.

The caulk has the appearance of a flattened blade made of wood with a long handle and a narrowed base. One side looks like a handle, the other looks like a spatula.

Options for caulking a house from a bar

Such activities are carried out in two ways, which depend on the width of the gaps. For the most part, such gaps are very small in the gap between the logs, so it is advisable to use the stretching technique here. Thanks to her, insulating fibers are placed along the opening, after which they are driven inward with the help of caulking. Thus, it should be continued until the gap finally disappears.

The presence of large gaps between the seams gives rise to the use of the "set" method. The insulating material is twisted in the form of thin and long ropes, the thickness of which corresponds to the gap. The gaps must be completely closed. To check the quality of the work, you need to use a kitchen knife, which you need to push into the slot.

When it penetrates into a gap of 1.5 cm or less, we can talk about a good quality of insulation. When deeply deepening this object, you need to add another layer of insulating material. In the process of work, you should be careful: excessively applied forces can lead to the separation of the laid timber.

Caulking at home with jute fiber gives good results.

It is worth noting that the process of insulating a building by plugging cracks with insulating materials is not as simple as it seems at first glance. Efforts for high-quality work must be applied to the maximum, the layers should be hammered 3 times: first at the time of construction, then after 1 year and after the completion of the process of natural shrinkage. Caulking can take up to 5 years.

These measures must be carried out on time, which will save from drafts, condensation and wood decay. A well-done work contributes to a good sealing of the seams and the complete absence of cracks in the walls.

It has happened: a new wooden handsome man has grown on your site - a house. Behind the agony of choosing an architectural style, a suitable project and building material.

Your choice fell on a profiled beam, and you were not mistaken. The realized result of your dreams - a neat, neat and pleasing structure with its impeccable geometry - will serve you and your household for a long time and reliably.
By the way, when you were deciding on the material, you were convinced that the timber walls do not require caulking. They said that a timber is not a log; here everything is smooth, and in principle there can be no gaps. In addition, when assembling a house, builders will definitely lay a layer of insulation between the crowns, so that no cold can penetrate into your home.
You didn’t believe it, and you did the right thing.

Mezhventsovy insulation, no matter how wonderful it is, is only a partial protection of the walls from bad weather.

There are always gaps between adjacent rows of timber, through which atmospheric moisture easily penetrates, and the wind freely walks.
Caulking protects the material laid between the crowns, prevents it from damp and rot, and at the same time insulates the house, preventing drafts and eliminating cold bridges. Therefore, you need to stock up on materials and tools for caulking and immediately begin the process of sealing joints and cracks.
It seems to many that this is a simple and not requiring special knowledge. But, as in any business, there are rules here. You need to familiarize yourself with them before you take on work. This is important because a careless and superficial attitude can lead to big trouble; for example, like this:

• distortion of the log house due to uneven filling of the seams;
• dampness and blackening of wood, which in the future will lead to the appearance of mold and rot;
• the appearance of "hares" (as in the professional language are called sections of the wall where icing occurs, caused by heat leakage to the outside). In winter, they should be noted, and with the arrival of warm weather, it is good to dig in all problem areas.

Neglect of these rules as a result can result in a large amount of work on alteration of carelessly made caulk, and, as a result, considerable and unjustified financial losses. "Tyap-lyap" in construction is expensive. Therefore, it is better to immediately tune in to painstaking and thorough work.

Log house caulking technology

It all starts with the right tool. See what you need:
1. Ladder - stepladder (it will not work to caulk the upper crowns from the floor).
2. Caulk (this is the name of a chisel-like object). With the help of caulking, you will seal the insulation material into the seams between the joints. Ideally, it should be made of wood, but let's be honest: most professional craftsmen use metal tools, considering them to be more reliable in operation.
3. Mallet (the so-called wooden hammer). The master taps with it on the caulk when he hammers the next portion of the insulation material deep into the gap. Varieties of this percussion instrument: rubber or steel hammer. It is clear that the second one is not used together with a wooden caulk if they do not want to smash it to smithereens after a few blows.
4. A knife (you can use a simple clerical one) for cutting the jute tape - in case you decide to bury the house with this particular material.
5. Cloth gloves, if necessary.
6. Available material for caulking: moss, tow, jute, linen or something else.
Professionals advise: When choosing a hammer - mallet, take into account its optimal weight. Too light will not allow you to close the seam tightly, too heavy - inconvenient to work with. Most craftsmen agree that the "correct" hammer should weigh one and a half to two kilograms. It is advisable to equip the handle of the mallet with a wide protective ring made of dense rubber so that the blow of the hammer does not fall on the fingers of the master.
Caulk sequentially - from bottom to top, and immediately along the entire perimeter. The lower rim is bored first; first they pass along the outer wall, then go to the inner wall. Having finished working with the first crown (and the numbering of the timber always goes from bottom to top), they proceed to caulking the second. And so on to the very top.
This sequence is very important, as it avoids skewing the structure. After all, caulking makes the house "grow"; its height increases, on average, by 10 cm. The material must be hammered without extra effort; everything should be in moderation.
Natural materials are used to seal the grooves:

• moss (where it grows) is the undisputed leader among insulation materials;
• tow is one of the most popular heaters;
• hemp - currently not used often;
• jute tapes - a controversial material for caulking; many believe that jute strongly draws in moisture, therefore it is suitable only as an inter-crown gasket;
• flax is a good material for caulking, provided that the flax content does not exceed 10%;
  and others, less common.

There are two types of caulking: in a pigtail (tow) and in a set (linen). In both cases, a tight rope-like roller is formed.

How experienced masters work with tow - caulkers

1. Oakum along the entire seam with a movement from right to left is "hung" in strands one and a half to two widths of the beam (depends on the width of the gap between the crowns).
2. The upper part of the strand is roughly hammered into the gap.
3. When the crown is completely closed, the master moves in the opposite direction - from left to right; he lifts and captures 1-2 cm of the strand, after which he hammers it into the seam.
4. New movement from right to left - now the strand is rolled up with a roller, and its lower part is embedded in the slot. It turns out a continuous row of the roller.
5. The master is now moving to the right corner of the log house, finally closing the wide roller, gradually turning it into a thin, neat and barely noticeable inside the seam.
6. Result: a beautiful inter-crown seam - even and without rags.
Professionals advise: Use only clean combed tow, no matter if it is jute or linen. The main thing is that it should be free of debris and impurities.

Techniques for working with flax

1. First, only the upper edge of the tape is hammered into the groove, the lower one simply hangs down. A second tape is placed under it, twisted into a bundle.
2. The bottom edge of the first top tape is padded.
3. The gradual embedding of the material leads to the fact that the seam becomes even and tight; it should not be easily crushed by your fingers.
4. An experienced caulker at a glance determines the required number of tapes for seam placement.
Professionals advise: The wider the seam, the more insulation tapes will be required. There may be three or four of them.

The best choice of caulking material to minimize further heat loss

The choice of insulation material for caulking depends on several factors:

• locality. If moss grows there, especially red, then nothing else is worth looking for;
• production located nearby. If there is a tow factory nearby, you will not have to order expensive jute;
• the financial capabilities of the owner. Most likely, you will have to pay attention to a more budget option. At the same time, it is reasonable to study the offers of several suppliers of caulking material, since the price for it can differ significantly.

In any case, the insulation must meet several important requirements:

• environmental friendliness;
• low thermal conductivity;
• hygroscopicity;
• breathability;
• mold and mildew resistance;
• durability.

Optimal caulking time

The caulking of a bar is carried out in several stages:
the first is preliminary: it is performed immediately after the assembly of the house kit on the site. The insulation material is not very tightly inserted into the grooves between the joints, and so it is left for the period of the initial shrinkage of the house: this is a year or a year and a half.
the second is the main one: the initial settlement of the house by this moment has already occurred, and it is imperative to seal all cracks, grooves and joints with careful observance of all technology. The better you do the job at this stage, the warmer and more durable your home will be. This stage is also considered to be the main one because at this time many begin finishing the facade (for example, with siding), after which it will be problematic to fix the flaws in the caulking.
the third is fixing: it is believed that it shrinks completely five to six years after its construction. By this time, the caulking material had condensed from the weight of the crowns, “fused” with the timber and acquired its final appearance.
You can make sure how well the caulk keeps heat by revising the seams and joints. If you used tow, then some of it could be taken away by birds. Therefore, you will have to add material to where voids have formed, or where the caulk has lost its density.
Qualitatively, with a soul, made caulking will delight more than one generation of your family; will keep your home warm and cozy for many years. And if you are lucky to buy a high-quality timber that does not rot before the caulk collapses, then your family nest will have time to please your heirs.

Houses from a bar have always been distinguished by their attractiveness not only in appearance, but also in terms of technical characteristics. Their popularity in individual construction is widespread due to the availability of a large selection of materials. However, in addition to this, wooden houses are also distinguished by environmental friendliness.

However, buildings made of wood also have disadvantages, the main one of which is the formation of gaps between the components of the structure. This is caused precisely by the naturalness of the material itself. Firstly, even the factory processing of wood will not provide and will not guarantee a perfect flat surface and absolute adhesion of the beams. And secondly, the shrinkage of the material. Billets that have undergone heat treatment still have a certain percentage of moisture. In order for the building to look presentable and to keep warm, it is necessary to caulk the building.

Stages of work:

	Preparation of tools and materials, selection of insulation options.
	Caulking at home from a bar. Choosing a suitable caulking method, identifying problem areas, performing work.
	Checking and finishing (if necessary).

How to caulk a house from a bar. Video

Caulking a log house is nothing more than a process that maximizes the compaction of the space between the crowns and logs. Such a seal of the gaps will help to save heat inside the room and maintain the optimal temperature regime.

Materials and tools: how and what to caulk

The caulking tool should be comfortable and correctly selected. For a long time, the following tools have been used for these purposes:

• curve caulking;
• typesetting caulk;
• split caulk;
• road builder;
• mallet (mushel).

To date, the most popular material for caulking is used by mezhventsovye tape seals. Their production is carried out using jute or flax. During the assembly of the log house, they are placed in the grooves, after which they are fixed with a construction stapler. Jute sealant gives off moisture well, does not rot, and is not interesting for birds. When the frame shrinks, the sealant lays down evenly.

Of the nonwovens, linen is considered the most affordable. Its distinctive qualities include elasticity, good heat retention and durability. For the caulking procedure, it is made in the form of linseed tow and eurola (flax fibers). However, it should be borne in mind that flax attracts the attention of birds and can be affected by insects.

In addition to these materials, others are also used:

• Moss is a natural material for sealing the inter-crown space, which has been tested for centuries. It has bioactive properties, excellent protection against the appearance and spread of mold. Swamp red moss easily withstands extreme temperature changes. In addition, forest moss, or as it is also called cuckoo flax, can be used for caulking.

• Wool is a material that deserves special attention. Sheep wool surpasses any type of wood in its thermal insulation properties. The material works on the principle of a spring, that is, when assembling a log house, a 20 mm thick seal can be compressed up to 6 mm. During the shrinkage of the bars, the wool expands, filling the voids.

• Tow and felt - it is on the basis of these natural materials that the insulation is made. In addition to naturalness, their advantage is excellent thermal insulation properties and prevention of drafts. But there are also disadvantages, which include a short shelf life and the ability to absorb moisture.

• Artificial materials made on the basis of mineral wool and polyethylene foam.

When choosing a heater, you can use other materials, but provided that they meet the following parameters:

• have low thermal conductivity;
• resistant to insects and microbes;
• the composition does not contain harmful and toxic elements / substances;
• resistant to external and internal factors, for example, to strong winds or high levels of humidity;
• they must not have or give off unpleasant odors.
• a mandatory parameter for any insulation is durability. The term of their application without loss of all qualities and properties should be at least 20 years.

Tip: You must be able to distinguish between ordinary felt and the jute variety, since the latter is the moth's favorite material. In addition, jute felt can rot.

Types and methods of caulking a house from a bar. Video

In total, there are two types of caulking:

• Primary - a process that is carried out at the stage of construction of a log house. In this case, the material used is placed in the log row.

• The final caulking occurs 7-12 months after the assembly of the log house. For this, builders use special equipment, with the help of which the thermal insulation material is again placed in gaps and voids.

In addition, there are two ways to caulk:

1. "In the set."

Caulking of wide voids. To carry out the process, the seal is twisted into a kind of strands 20 mm thick, after which they are wound, in small sizes, into a ball. The filling of the free space starts at the top edge and gradually moves towards the bottom. After that, the road builder is used.

1. Stretching.

Insulation is applied to the groove. With his hands, it is pushed inward, after which the remaining edges are tucked in and, with the help of caulking, are hammered inward. In order to competently perform all the necessary steps, it is recommended that you familiarize yourself with the video.

Caulking a house from a bar: insulation from the inside

After caulking the walls from the outside, you should carefully do a similar process inside the log house. Building a house from laminated veneer lumber also implies insulation from the inside. In order to do everything correctly, it is worth adhering to the same rules, that is, to perform caulking of the groove only along the perimeter of the walls. You should prepare the tool for work in advance.

Tip: any excess insulation is best cut off completely to the very edge of the groove. When carrying out caulking of internal walls, this is the main condition if the building will not be sheathed with any finishing material afterwards.

Indoor walls should have an aesthetic appearance. Therefore, the choice of material for insulation must be approached doubly carefully. The grooves should be carefully repaired, so that in the future there would be no violations of the general interior. Inside the building, the insulation is checked every three years. Exterior walls need to be caulked when assembling a log frame, after one year, and then after five years. In the future, this procedure should be carried out as needed. If you look at our video, you can learn more about the procedure for internal caulking at home.

Tips from professionals

Do-it-yourself caulking is a scrupulous and time-consuming work, during which you must make every effort. In order for the actions to be carried out to be as effective as possible, one should not only select and prepare tools, but also get acquainted with some tips and recommendations of experienced specialists.

Firstly, in order to avoid distortions in the structure of the building, it is not necessary to process each wall in turn. It is necessary to carry out work around the whole house, around the perimeter, starting from the bottom and gradually moving higher. After watching our video, the execution technology will become more clear.

Secondly, it should be borne in mind that high-quality work will increase the height of the building by at least 10 cm. This should be foreseen even during the design so that no difficulties arise.

Thirdly, when erecting a log house, the insulation should be laid between the rows. It is necessary to remember about the need for the final caulking of the walls. To do this, you will need to lay the insulation material before the cut of the wall so that there is a free space of 3-4 cm. Most often, the road builder tool is used for such purposes, which allows you to correctly and efficiently lay the insulation when sealing the gaps.

The cost of caulking a house from a bar

The feasibility of performing caulking the walls with your own hands will largely depend on the availability of experience and time. The construction of a house from a profiled bar requires additional caulking, however, due to the complexity of the castle type of connection, it is extremely difficult to carry out it yourself. Therefore, it makes sense to contact a specialist.

The price of work is made up of several factors:

• the type of diagrams and blanks that are used in the process of building a house from a bar;
• total area;
• the number of crowns together with corner joints;
• degree of material processing.

A badly burnt log house can lose its symmetry in a short period of time, for this reason the whole procedure must be carried out deliberately and accurately. It is recommended to contact a specialist to avoid the formation of any problems.

You were told that it is not necessary to caulk a house from a bar, they say, everything is perfectly fitted there anyway? You can safely send such "grief" specialists home and invite real professionals in the construction of wooden houses.

Like any other, the technology of building houses from a bar has its own stages and design features, which invariably include caulking a log house, even if you are going to do external and internal finishing with insulation in the future. You should not try to save time and money, so as not to overpay in the future. If you do not want drafts to constantly walk in your house, curtains flutter even in calm weather, and over time, wet and rotten places in the wood appear, it is better to do all the caulking work at home on time.

Is it necessary to caulk a log house and why

In some sources you can find information that a log house can not be caulked. And the builders who are building your house can say the same thing. They explain this by the fact that, unlike log houses, shrinkage and displacement of wood occurs more and more intensively in log houses, cracks and leaks appear, so it is imperative to dig the structure. But houses built from profiled timber practically do not sit down, since the wood is pre-processed. Let's see how it actually happens when building a house from a bar with your own hands.

Natural moisture bar- a relatively cheap building material, for which it is popular in the construction of economy-class houses with subsequent insulation and siding. Even if you invite the best architect, he will not be able to build a house from such a bar without gaps between the crowns and gaps. Moreover, when the timber starts to dry out, and this is inevitable, additional cracks will appear, wider, the timber will decrease in size, it will begin to "twist". As a result, such gaps will appear, due to which the wooden wall will lose its thermal insulation capabilities. To avoid such a sad end, the walls must be buried at least 3 times and carefully insulated.

Profiled timber was invented precisely in order to reduce the costs and time for the construction of a wooden house. It undergoes special processing in production, due to which it practically does not dry out during operation, and its tongue-and-groove connections are perfectly calibrated to the nearest millimeter. The bar adjoins each other as tightly as possible, and a 5 mm insulation is placed between the crowns, which is located between the engaging parts. Despite the seller's assurances, the house made of profiled timber still shrinks, since the timber finally falls into place under the weight of the building. In addition, the properties of wood are highly dependent on the region of growth, climatic conditions and storage conditions. No one can guarantee that absolutely all the timber you have purchased is of the same high quality. As a result of the movement of the building, the timber may slightly shift, the insulation wrinkle. Even if no cracks appear after shrinkage, and this option is possible, all the same, those gaps that are in the space between the joints outside and inside the house accumulate moisture, and since the place itself is very secluded and vulnerable, mold and rot can form in it.

Caulking of a log house is necessary in order to insulate wooden walls, completely filling them with natural insulation and sealing the gaps and gaps between the timber and in the corner joints. This guarantees tightness, no heat leakage through the walls, no drafts and no icing of the timber outside the building, which occurs when warm steam comes out through the cracks and settles with wet frost on the surface.

How to caulk a log house

To summarize, the material with which you can dig a house must meet the following requirements:

• Have low thermal conductivity.
• Be immune to temperature and humidity fluctuations, and easily withstand the wind.
• To prevent insects and pathogenic fungi (mold) from growing in it.
• To be absolutely environmentally friendly material, otherwise the whole point of building a wooden house is lost.
• Be relatively durable (do not lose properties for at least 20 years).
• Be breathable.
• Be hygroscopic, i.e. when it is necessary to absorb moisture, when it is necessary to give it away.
• And the most important thing is to be similar in its properties to wood.

Due to the fact that our ancestors for hundreds of generations caulked their homes on their own, materials that have been tested and tested by thousands of years of successful practice have survived to this day. They can be called traditional materials.

Moss- the best material even today for caulking wooden buildings. This sphagnum moss is a marsh plant that can be red, white or brown. Subsequently, peat is formed from it. None of the modern materials can compare with moss, it is so durable and environmentally friendly. You can drive through the old abandoned villages, look at the houses: the logs are almost rotted, and the moss is still in excellent condition. As a mezhventsovy sealant, moss is simply irreplaceable: it has antiseptic, antibacterial and medicinal properties. Sandwiched between wood, it inhibits the development of putrefactive bacteria and molds, due to which the wood lasts longer. Moss easily passes air through itself, which, passing through it, is saturated with healing vapors, so the atmosphere inside the house becomes healing. Moss is hygroscopic, which means it smoothes out fluctuations in humidity. In general, moss has no drawbacks, except for one thing - it is not so easy for them to caulk, otherwise no one would have invented or looked for anything new.

Linen fiber tow it is used as a sealant and sealant everywhere, but for caulking - mainly in regions where flax grows and where there are no swamps, where you could stock up on moss. No one produces hemp on purpose, it is waste from the production of ropes, cords and cloth or stripping and stripping after cleaning flax fibers. Hemp has some antiseptic and bactericidal properties, but to a lesser extent than moss. Therefore, in some cases, the tow is treated with resins to increase resistance to high humidity. These resins can be natural, i.e. resin of trees, then this material can still be called environmentally friendly, but oil products are also used for impregnation, then tow has nothing to do with natural materials. The tow contains a large amount of fire, which will shake out during the first years of using the house, so the caulking will need to be repeated several times.

Hemp hemp very similar to tow, only its fibers are coarser, so they are sometimes confused. Hemp is not afraid of temperature extremes and high humidity, so it can be used even in very humid regions. These properties are due to the high content of lignin polymer, which is also found in any wood for bonding cellulose fibers. Hemp does not lose its properties even after getting wet, therefore it is resistant to decay.

Among modern materials for caulking are the following:

Jute- a foreign product, it is imported to us from China, India, Egypt and other countries with a tropical climate or heavy rainfall. It is made from the shoots of the jute plant of the Malvov family. Jute fiber is very durable, not affected by mold, putrefactive bacteria, not interesting to insects and birds, hygroscopic, i.e. easily accumulates and releases moisture, allows air to pass through. Jute contains about the same amount of lignin as wood, so their properties are similar and together they are a perfect match.

Jute is produced both in fibers and in strips of various widths. Jute tape heaters very convenient to use for laying between the crowns of a log house. In addition, pure jute compresses evenly. These advantages more than exceed the price of this material.

In addition to materials made of fibers for caulking, felt insulation (inter-crown felt) are also used:

Jute mezhventsovy insulation consists of 90% jute and 10% flax. But it is better to follow this ratio, since there is jute felt, 70% consisting of jute and 30% of flax, which significantly impairs its properties.

Linen felt also called Eurolene or flax. It is a needle-punched material made from highly refined linen.

Flax-jute felt consists of jute and flax in a 1: 1 ratio.

Fully modern jute heaters are considered the best, since they perfectly interact with wood and shrink evenly, while other materials with the addition of flax deteriorate the properties of the insulation. The more flax, the worse the properties.

When to caulk a log house

Caulking work at home is carried out in several stages, this is due to the fact that the timber dries out gradually, the house sinks under its weight. The largest shrinkage occurs in the first year and a half after construction, and every year it is less and less. Experts say that after 5-6 years, shrinkage practically stops.

First time a log house is caulked immediately after construction. During the construction process, insulation is laid between the crowns, and after the whole house is erected, the gaps between the beams are filled with caulking material, but not too tightly.

Second caulk produced a year and a half after the completion of the construction of the house. The house will already sit down, so it is necessary to caulk it tightly, leaving no gaps and hanging material.

Third time caulking work will have to be done again after 5 - 6 years, carefully filling in all the newly formed gaps and crevices and adding material where it accidentally spilled out or was pulled out by birds.

If the log house is planned to be sheathed with siding from the outside, then the third caulking is not made, but the first two must be performed without fail. You should not rush and save on what you will later have to pay much more for.

Caulking is a very responsible and time-consuming process, despite a certain monotony of the operations performed. Not many construction crews agree to caulk work, they simply do not know how to do it and are afraid to spoil it, which is why they recommend not caulking at all. We have already figured out why you shouldn't listen to them.

But there are teams and entire organizations that professionally deal with caulking. For caulking a log house, the price depends on the stage of work and is a certain amount for 1 linear meter of each crown. The average cost of caulking is 50-60 rubles. for 1 lm And caulking of corner joints can reach 200 rubles. for 1 lm At a separate rate, caulking will be carried out with a decorative rope (rope), which decorates the appearance of the bored walls and prevents the birds from pulling out the material. By the way, it is customary to pay for the material separately. If you are offered to perform caulking work for 25 rubles. m.p., it is not worth agreeing, since the work will be done out of the ordinary.

If you want to do all the work yourself, then please be patient, material, tool and further information.

How to dig a log house with jute

Jute, as a material for insulating a log house, is gaining frenzied popularity. It is often used in the construction of the house itself.

Before caulking a log house, you first need to properly lay and fix the timber. Insulation is always placed in the space between the crowns with a layer of at least 5 mm. Even if the timber is profiled, jute must be laid between the spike and the groove. But its width depends on the shape of the thorn-groove system. The simplest option is when the lower beam has a surface convex with a crescent, and the upper one has the same recess (somewhat reminiscent of the connection of logs), in which case the space between the crowns is completely filled with insulation, and its edges remain hanging by 4 - 5 cm on each side. A more complex version of a profiled bar, when it is impossible to lay the insulation with a continuous carpet, then it fits only in the middle, and the external and internal slots are then caulked separately.

If the house is a timber of natural moisture, then the thickness of the mezhventsovy insulation should be 10 - 15 mm.

Important! Caulking must be done from top to bottom. In this case, first one crown is caulked completely outside, then inside, and only then they move on to the second crown. It is better if the work will be carried out by 4 people at the same time on 4 walls. This is necessary so that the house does not warp. After all, after the caulking is completed, it will rise a few centimeters, from 5 to 15 cm.

Consider the option when the insulation hangs between the beams by 4 - 5 cm. The caulking technology is very well shown in the video example. With the help of a caulking tool (tool), the jute is tucked under the bottom and slightly pushed into the gap. Then, neatly, but already more strongly, it is pushed in the upper part, and finally - in the middle. To push the material into the slot, a rubber or wooden hammer (mallet) is used, which is gently hit on the caulk.

If, after the work performed, loosely clogged cracks are still observed, then additional caulking is performed.

Consider the option when the gaps between the crowns are not filled (the insulation is somewhere in the middle of the timber). The work will be exactly the same as with additional caulking.

Usually, the gaps between the bars are rather narrow, so this method of caulking is used: a rope with a gap is twisted from jute fiber and hammered into the gap with a mallet.

There is one more way - "stretching". Separately taken jute fibers are laid with fibers across the bar and pushed inward with a spatula or caulk until the gap is completely filled. We leave the remaining ends of the material hanging down, it should turn out to be about 5 - 6 cm.Further, a little more jute is taken, rolled into a ball (roller), which is wrapped in these hanging ends and pushed into the slot.

Important! How can you check if it's enough to push in the insulation or if you still need to add a little? If a kitchen knife enters the gap between the crowns by 15 mm or less, then the caulking is successful. If the knife goes further, then the material should be added.

When large gaps are formed, the caulking method "in a set" is used. Long strands are twisted from jute and rolled into a ball. Then loops are drawn from the ball and pushed into the slots until they are filled.

After the completion of all caulking work, the house is loaded and, if possible, is operated for a whole year. In winter, it will be possible to check for gaps by the so-called "hares". These are pockets of frost on the outside of the wall. If you find them, mark the place, this means that there is a leak of warm air from the house. A year and a half after the first caulking, the second is made, the house is carefully inspected, insulation is added to the places where it spilled out or frayed, where the cracks have increased, where the timber is warped, as well as in the places of "hares".

Only after re-caulking can you start interior and exterior decoration of the house. Even if it assumes 100 mm of mineral wool and a ventilated facade.

You can also dig a log house with other materials. But there are some exceptions. For example, you can caulk only a house made of non-profiled timber with moss, since this material fits and fills the space between the crowns, which is absolutely impossible if the timber has a thorn-groove system. The work itself on caulking at home is complex and painstaking, although it seems painfully simple from the outside. If you are not confident in your abilities, invite a specialist.

Absolutely any technology for the construction of a log house assumes that wall insulation will also be carried out in the process. It doesn't matter if the plans include finishing the house, insulating it, installing siding, caulking the house from a bar still needs to be done.

Why do you need caulk

A whole article can be devoted to this process, since at least several main points in the operation of the house depend on it:

• Elimination of drafts, which can form when there is no insulation between the crowns.
• Elimination of moisture penetration through the cracks between wood in the walls... Even the most perfectly fitted profiled timber does not provide a 100% seal.
• Exclusion of "cold bridges"... Without caulking between the pieces of wood, between the crowns, cold conductors will still form, and the house will not provide a normal and comfortable atmosphere.

Accordingly, one can easily answer the question of whether it is necessary to caulk a house from a bar, even proceeding from these points.

And to summarize the answer, you can add the list of advantages that are obtained with caulking:

• Tightness, and the absence of ways for heat leakage from the premises.
• No icing of the log house from the outside.
• Increase in the service life of wood, and, accordingly, the whole house.

What to use in work

Any material that can be selected for caulking must meet certain requirements, which are easily reflected in the listing below:

• Low thermal conductivity.
• Insulation should not perceive temperature fluctuations, as well as fluctuations in humidity.
• Antiseptic properties. should not become a "home" for insects and mold with fungus.
• The service life of the material must be at least 20 years.
• The material must be airtight.
• Possess hygroscopic properties.
• Be similar in properties to wood.

So, the instructions for choosing a material are clear, now you can briefly consider the most popular materials that have been used for many generations in the construction of wooden houses.

Moss

What is most interesting about caulking is the options for using materials that in another situation could not even be thought of in this way.

This is how you can perceive the fact that one of the best materials for this kind of work is sphagnum moss.

It has its advantages:

• Durability. Moreover, sometimes you can find old houses in which logs have rotted, but not moss.
• Environmental friendliness. Natural material, ideal for interaction with both wood and humans.
• It has all the necessary antiseptic and antibacterial properties.
• Possesses the necessary hygroscopicity.

Important!
Moss really does not have a single external minus, except for the difficulty in use.
For the inexperienced builder, interacting with moss will be a real challenge!

Tow

Tow, as a sealant or sealant, is found quite often in various works, but as a material for caulking, it is much less common.

With tow, the caulking of a bar to a lesser extent than with moss will respond to a huge number of advantages of the material, but at the same time the compaction is much easier to carry out. To do this, tow is often treated with a resin solution, which instantly increases its resistance to moisture, and raises its durability in service. In addition to resins, oil products can be used to impregnate tow.

Jute

But this insulation is an overseas product, and the main importers are countries with a tropical climate and abundant rainfall. Insulation is made from the Jute tree of the same name.

It is worth noting that jute has the same set of useful qualities as moss, and in its composition is as close to a bar as possible. In addition, jute is produced both in the form of a tape and in the form of a fiber. With tape, it is just very easy to work with your own hands when you need to lay the tape evenly.

When to start caulking

The process is always carried out in several stages, and this is due to the physical properties of wood, the timber gradually dries up and the house sinks under its own weight.

The caulking process can be broken down into three stages:

• Immediately after construction. Insulation is immediately placed between the crowns, and after the house is built, the gaps are filled with material, but not tightly.
• The process is repeated a second time after about 18 months. In this case, the caulking of the profiled bar is already tight and so that the material does not hang out of the cracks.
• Caulking can be carried out for the third time after 5-6 years. This is done if the house had not acquired external siding or brick cladding by that time. All cracks are carefully processed with the selected material and clogged tightly.

Work

Actually, now that the entire theoretical basis has been studied, you can start independent work.

The first stage is not even a process after the construction of a house, but during its construction. And here it is important to immediately start laying jute tape in the space between the crowns.

Important!
If the house is being built from a dry profiled timber, then you can use a tape 4 mm thick, and if from a timber of natural moisture, then the jute should be at least 10-15 mm thick.

Using jute tape during construction, it turns out that on both sides the insulation simply hangs between the beams. Next, using a special tool. It is also called "cauldron", the jute is wrapped under the bottom and pushed a little into the gap between the crowns. Then, the same is done with the top level and in the middle.

In order for the material to normally be pushed into the gap between the crowns, you can use a rubber hammer, which beats on the caulk. That is, the insulation is based on the principle of driving in a wedge.

There is nothing complicated in how to caulk a house from a bar on your own, no. The main thing is, after all the work has been done, once again inspect the gaps between the crowns, and if there are suspicious places, make an additional seal.

There is another option in which the insulation was not wide enough, and its edges did not come out of the cracks between the timber. In this case, an additional caulking event is simply held.

For this, a kind of rope is twisted from jute fiber, which is hammered into the slot.

You can also work "in stretching", jute fibers are laid across the masonry of the timber and driven in with a "caulk" until it stops in the cracks. The ends of the fibers are wrapped in a roller, and are also hammered into the slot.

Output

The price of caulking work can be from 50 rubles per one running meter, therefore, independent execution, of course, will significantly save on the overall construction estimate.

The main thing is to maintain harmony between rational approaches to costs and quality of work. And in the video in this article, you will find useful and visual information on this issue.
