What is the right way to caulk a log house. Caulker of a wooden house - methods and stages

Caulking a log house is a job that our ancestors did. It was in this way that they closed the cracks in their wooden houses. Today there are more modern methods of insulation, but caulking is still one of the most popular options for sealing seams and joints between logs. Caulking is made with natural materials that breathe with the wood and do not interfere with the air exchange of the wood. Caulking is a difficult job that requires not only skills and experience, but also great patience. If you want to try your hand, you need to study in detail how to caulk a house from a bar. There are many nuances in this matter, without knowing which a good and high-quality caulking will not work. Therefore, we will dwell in more detail on how to make a caulk.

Caulking is performed several times. For the first time it is carried out immediately after the construction of the house, the second time the log house is caulked a year and a half after construction. During this time, it undergoes a shrinkage process, new cracks and gaps appear between the logs that need to be closed.

All wooden houses are deformed, perhaps only glued timber is an exception. Houses made of profiled timber of natural humidity are especially susceptible to deformation. During the shrinkage period, cracks may appear in the wood itself, which will be removed as a result of caulking. Often, the caulking of a house made of logs and timber is carried out again five to six years after construction.

Primary caulking can be performed at different times:

1. Directly during the construction of a log cabin of a bathhouse or a house. In this case, the insulation is placed between the rows of logs. First, its edges hang evenly on both sides, and then, after the frame is placed under the roof, they are hammered into the interventional seams.
2. Immediately after the construction of the house. The insulation is applied to the seam and, with the help of a tool, is pushed into the gaps between the beams.

Do-it-yourself caulking of a log house begins with the lower crowns. First, the bottom row of logs is caulked around the entire perimeter of the house on both sides, then the second, third, and so on to the end. You can not caulk the house first on one side, and then proceed to the second and subsequent ones. The caulk raises the wall by about 5-10 cm, so if you caulk the bath on one side, the whole house cannot be skewed.

For caulking, only natural materials are used, which:

• hygroscopic,
• immune to temperature fluctuations;
• breathable;
• environmentally friendly;
• similar in properties to wood.

These characteristics are:

• tow;
• jute;
• lnovatin.

Many people ask themselves: how to caulk a house from a bar? All the above materials are suitable for caulking both timber and log houses, there is no difference.

Moss

It is considered one of the best materials for caulking. No wonder our ancestors caulked with moss. Among other things, it has antibacterial properties and protects wood from pests and mold. However, getting this natural insulation today is very problematic. It is difficult to find it in free sale, you can, of course, prepare it yourself, but it is not so easy.

Tow is a waste that has arisen after the primary processing of natural fibers of flax, hemp and jute. Its characteristics entirely depend on the properties of the feedstock. The insulation can be pressed into bales or tied into ribbons. Hard and short fibers are collected in bales, which are not very convenient to work with, the rolled material is softer and more pliable in work.

Tow has slightly pronounced antibacterial properties. However, this insulation strongly absorbs moisture, which in a few years can adversely affect the wood. After laying, it is necessary to impregnate the tow with special impregnations or paint it with bird protection paint.

Jute

Produced from plants growing in China, India, Egypt. Available in the form of ropes, fibers or tapes. The insulation is easy to use, durable, due to the large amount of natural resin, mold does not form in it and microorganisms do not appear. Even at high humidity, the material remains dry.

Lnovatin

It is a needle-punched fabric produced in rolls. The material is completely ready for use and does not require any preparation. The insulation is made from short fibers of highly purified flax. Lnovatin is characterized by high heat-saving qualities, is not subject to decay, does not accumulate moisture in itself.

Caulking technology

There are two main methods of caulking:

1. "Stretch". The material is pushed with a special tool into the gap, tightly filling it with insulation. The rest of the material is wrapped in a roller, which is strongly pushed into the empty space between the logs.
2. "Vnabor". This method closes up wide cracks and gaps. Bundles are twisted from the material, which are then folded into loops. The loops are pushed into the holes between the logs and fill the free space with them.

Regardless of which method is used to caulk, proper caulking always starts from the lowest row of logs. Next, we will consider in detail how to properly caulk a log house.

Caulker "stretched"

Caulk with fibrous insulation

1. Caulking starts from the ends of the bottom row. They take a bunch of moss or tow in their hands and apply it across the fibers to the gap, then press it inward with a caulking blade.
2. The edges of the fibers are folded into a tight roller, applied to the seam and pushed into the cracks with a caulk, while the end is left hanging outside.
3. They take new strands of tow, weave them into the free edge of the roller and repeat the steps in the same sequence. It is necessary to tightly and evenly caulk the entire seam. Therefore, it is very important that the roller is not interrupted and is solid along its entire length.

Caulking with roll material

When using tape heaters, it is much easier to twist the roller. The material is slightly stretched along the seam, which allows you to more evenly distribute the insulation. The material must be applied to the seam across the fibers; with a longitudinal arrangement, it is impossible to achieve the desired density.

1. The tape is unwound from one corner of the log house to the other, without pulling, but leaving it free to lie on the ground.
2. They take the tape by the edge and push the middle of the material into the seams between the logs with a caulk, leaving the edges hanging down by 5-7 cm. The entire seam is filled in this way.
3. After the entire seam is initially filled, the tape can be cut from the roll.
4. Hammer the remaining material into the gaps between the bars. The caulked seam must be of uniform density and thickness and must protrude approximately 4 mm from the grooves.

Caulker "in set"

In this way, as a rule, wide gaps are caulked. In this case, more insulation is required, but the quality of insulation is much higher. For this, tow is used, from which long strands are made and wound into a ball. You can finish the frame with jute cords or hemp ropes, from which balls are also formed.

1. A little cord is unwound and folded into loops, which are alternately pushed into the seam with a caulk.
2. The loops are clogged with caulking, first from above the gap, and then from below.
3. Another strand is superimposed on top, with the help of which the final seal is made, then the strand is leveled with a triangular caulk.

To make the work a little easier and to fill the insulation faster, the process can be mechanized. To do this, the log house is caulked with a perforator, which is used instead of a traditional tool. But during operation, you can’t put much pressure on the puncher, otherwise its blade may get stuck between the logs, and you also need to take a break every 20 minutes. To drive the insulation, you can also use a pneumatic hammer with a compressor.

To give the seams a neat and beautiful look, on top of the caulk, you can finish the log house with a jute rope. Finishing does not insulate the house, but is purely for decorative purposes. How to fasten a rope for finishing a log house? The decorative cord is fastened with galvanized nails without caps, which are hammered into the upper and lower logs in 20 cm increments.

Grinding and painting of the house is carried out after the secondary caulking. How and how to paint a log house can be found in the article: "How to paint the facade of a wooden house."

Caulking corners

The corners are caulked after the main caulking is completed. It is more convenient to do this with the help of a roll insulation.

1. The edge of the tape is applied to the fillet weld and pushed inward with a curved caulk.
2. After fixing the material, tuck its edges and tightly hammer into the slots.
3. During operation, they move from the top seam to the bottom. In order for the material to lay down evenly, it needs to be stretched a little and constantly straightened.

How to check the quality of the log caulking? The tightness of the internal and external seams can be checked with a chisel or other sharp object that should not go through the caulk. The insulation should lie tightly, and the caulked seams should look neat and secure.

Do-It-Yourself Mistakes

It is not easy to make a caulk on your own. Lack of experience and lack of caulking skills lead to the fact that the work is of insufficient quality.

Typical mistakes that inexperienced craftsmen make:

1. Use of low quality insulation.
2. Improper preparation of material for work.
3. Violation of the sequence of work.
4. Caulking of the house on only one side, internal or external.
5. Caulking is not around the perimeter of the building, but along the walls.
6. Loose fit of the insulation and its protrusion from the seams.

Caulking will turn out to be of poor quality even if only one mistake is made. It doesn’t take long to become a specialist caulker. Experience in caulking is acquired over the years, so it is not surprising that inexperienced masters often make mistakes, which then have to be corrected by professionals.

From time immemorial, a wooden frame has served people as a warm, reliable home. And now many people prefer wood to brick and foam blocks. Wood is a living natural material. It breathes, changes shape, sometimes acts up. Therefore, it is important to know the little secrets of construction and follow the advice of experienced craftsmen. Experts know how to properly caulk a house from a bar in order to enjoy comfort in any weather. Having decided how and with what to caulk a house from a bar, you can get to work.

When purchasing a profiled beam, a person often hears that he does not need additional insulation. The beam is fitted closely to each other. A 5 mm thick insulation has already been laid between the crowns, it will protect against drafts.

In fact, the house is still shrinking a little under its own weight. Even industrially dried profiled lumber is affected by the weather. It can both gain moisture and dry out. Insignificantly, but this is enough for cracks, crevices and cold bridges to appear between the crowns. Following these, drafts will appear, moisture will penetrate into the walls. Thermal insulation also needs protection. Open, it can wrinkle, get wet and rot.

If a solid timber or a log with natural moisture has become the building material, then deformation during drying is inevitable.

Knowing how and how to caulk a house from a bar, you can avoid:

• drafts;
• moisture penetration and damage to wood and thermal insulation inside the wall;
• wall icing;
• heat loss.

After a well-made caulk, the log house will serve as a reliable refuge from the cold and will not require repairs for a long time.

Materials for caulking

When choosing how to caulk a house from a bar, you need to consider the basic requirements:

• low coefficient of thermal conductivity;
• immunity to temperature fluctuations;
• hygroscopicity;
• air tightness;
• wind resistance;
• durability (service life of 20 years);
• high antiseptic properties so that harmful insects, mold or fungus do not settle inside;
• ecological purity.

Indeed, since the house is built of wood, natural materials with similar properties should be used as interventional insulation.

These include:

• hemp hemp;
• wool;
• felt;
• other analogues.

Knowledgeable people usually use only a few of them in their work.

Moss

Moss is red and white. One of the most popular materials, known since ancient times.

Known today for its merits:

1. It is an environmentally friendly natural material.
2. It literally grows under your feet. The main thing is to be able to prepare.
3. It does not contain pests. On the contrary, the appearance and development of the fungus is excluded.
4. Resistant to temperature changes.
5. Absorbs excess moisture.
6. Has healing properties.
7. Its service life is almost infinite.

It is difficult to find it on sale, but you can assemble it yourself. They do this in late autumn, when the bulk of insects and snails have already gone into hibernation.

Natural moss requires serious processing. The earth and garbage are removed from it, then dried. Don't dry it too hard. From this, it will become fragile and will no longer be able to serve as a good insulation.

If you managed to buy ready-made moss, you need to soak it before starting work.

However, caulking with moss without the skill is very difficult.
If the caulking is not done well enough, the already laid moss is pulled out by the birds. For protection from above, they are stuffed with flashings or a decorative cord.

Tow

Tow is similar in thermal insulation properties to moss and is also loved by birds. It is also made from waste from the production of flax fibers. Sometimes hemp and jute are used.

Depending on the feedstock, there are bale and tape tow. The first consists of short fibers and is inconvenient for caulking. The second is considered almost ideal and is often used. But it contains a fire, it falls out, and the house has to be isolated again.

The big disadvantage of tow is the ability to accumulate moisture, which then begins to undermine the wood. To level this quality, the tow is impregnated with resins. Previously, it was wood resins, now petroleum products are increasingly common. This makes it impossible to call tow an environmentally friendly material.

Jute

Jute is a foreign material. It is produced in India, China and Egypt from a plant of the Malvaceae family. It compares favorably in that it does not attract the attention of birds. In addition, it is strong, durable, hygroscopic and completely similar in properties to the wood of the house.

Jute comes in the form of ropes, fibers and ribbons. Ribbons are most suitable for caulking the first and second stages. They are soft and pliable. Fibers and ropes are used in the third place.

Lnovatin

Lnovatin is made from flax, produced in the form of a canvas, immediately ready for use.
It retains heat better than others, does not rot and does not absorb water.

New types and forms of insulation appear regularly.

How to caulk a timber house

Caulking is carried out in three stages.

The first time the house was just built. Insulation is placed between the crowns and laid in the cracks.

The second time they caulk an already settled and settled house. This happens about a year and a half after construction. The insulation is pushed in tightly, leaving no space.

The third caulk should be done after 5-6 years, when the shrinkage of the house has almost stopped. If before that it was not additionally insulated from the outside and not covered with a finish.

There are several options for how to caulk a log house.

Stretched caulk, set

The stretching method is used for narrow gaps and cracks in the timber.

They use a special tool, which is called a caulk, and a mallet.

They start the process from the upper crowns, move down, go through one seam outside and inside. So that the house does not warp, it is better to work on all four walls at the same time.

First, the insulation is laid by hand, then pushed deeper with a caulk, at the end they hit it with a mallet to seal the insulation. Continue until the scapula enters the gap less than one and a half centimeters.

Sometimes a wide insulation tape is placed between the bars during the installation of the walls, so that it hangs on two sides. And then they push her inside.

After completion of the work, the height of the log house will increase by a dozen centimeters.

If the gaps have formed more than two centimeters, choose the "set-up" method.
The insulation tapes are cut off and twisted into bundles, the bundle is folded into loops, then pushed deep into the gap. Thus, all free space is filled. The final tape is applied from above and compacted with a triangular spatula.

How to caulk corners

To keep the house from getting cold, it is necessary to insulate the corners. They do it from the inside.
Take a crooked caulk, a long strand of insulation. Apply a strand to the seam, evenly distribute and push inward.

It is possible to insulate a house with your own hands, the main thing is to be patient.

Caulking, what to caulk and how to do it? Caulking cost?

In the article we will consider the following questions:
— How and what caulk a log house , or rather the gap between the logs of a wooden house.
- Caulking at home, from a log, as well as a log house from a log.

Caulker

Caulker- this is the work of filling and sealing grooves, cracks and gaps between the crowns of the log house and in places of corner cuts with heat-insulating material: tow, dry moss, hemp. This is a very time-consuming manual work that requires special skill and endurance from its performers.

In Russia, this work was carried out by masters - caulkers, whose art was passed down from generation to generation. The quality of their work could be fully appreciated in winter, when frosts set in.

Stages of caulking chopped walls.

Unfortunately, a layer of interventional insulation laid during the construction of a log house does not guarantee high-quality thermal insulation.

In addition, during operation, the walls of the house give serious shrinkage, and the thermal insulation properties of the insulation decrease, as a result of which the crowns of the log house appear.

To reduce heat loss and improve sound insulation, wooden ones need to be caulked. Typically, this procedure is caulk at home, execute several times.

The first time you need to caulk a log house immediately after its construction.

Secondarily, the frame is caulked a year or two after its partial shrinkage.

The third time the houses are caulked four to five years after the complete shrinkage of the log house.

And then wooden houses made of logs need to be caulked every two years, and “caulked” annually. However, there are “hard cases” where a house needs to be caulked every year, due to the fact that it was built with large violations of construction technologies and / or from low-quality logs, which resulted in very large gaps into which you can stick your palm

The main stages for caulking chopped walls.

Work on caulking at home must be carried out sequentially around the entire perimeter of the log house, starting from the lowest crown, rising in a circle higher. In this case, special attention must be paid to the sealing of corner joints.

At caulked chopped walls materials are spread with fibers across the groove and driven into the slots so that the fibers protrude from both sides of the log house by at least 4-6 cm. This work is performed using special devices, which are also called "caulks".

During the sealing of the gaps, periodic addition of fiber (insulation material) is allowed until the seams between the surface of the upper and lower logs are completely filled.

When laying fibrous material, it must be remembered that caulking can raise the height of the log house by as much as 15 cm, therefore, starting from the lowest groove, it is important to do this work around the perimeter of the entire log house (and not a single wall), otherwise caulking one individual wall can lead to skew the entire log house.

In the photo below - a modern version of the "caulk" - using high-tech wood sealant, but more on that a little later.

Types of caulking chopped walls.

There are two types of sealing and insulation of the walls of the log house - "in a set" and "in a stretch":

• Caulking at home "in a stretch" is used in grooves and crevices. Having made a strand of tow, put it against the slot (groove) and drive it in with a special spatula. This operation is repeated until the entire groove is filled. The stacked tow is carefully compacted. Then they make a roller out of tow, insert it into the groove and, grabbing the fibers protruding from there (otherwise it may fall out), drive it in with force.

• In wide grooves and crevices, the log house is caulked “in a set” - strands are twisted from tow or hemp and wound into a ball. Then loops are “gained” from the ball and hammered into the groove. The width of the strands depends on the depth and width of the groove between the logs.

Advantages and disadvantages of caulking.

Of course, caulking wooden walls is a good way to insulate. First of all, it is worth noting the environmental friendliness of traditionally used materials: tow, moss, hemp.

However, caulk also has its drawbacks.

First of all, given the laboriousness of its implementation, caulking is a rather laborious and expensive pleasure. At the same time, it should be understood that in order to achieve maximum efficiency, the log house must be qualitatively caulked more than once, during its operation. It is not difficult to calculate the amount of financial costs for this work.

Caulked seams do not look very aesthetically pleasing and often require additional ropes made of natural materials (see photo on the left) or other materials, which naturally entails additional costs.

It should also be mentioned that birds, our feathered friends, are very fond of pulling and pulling tow and moss from the seams between the log crowns. At the same time, this pulling apart takes on rampant proportions in the spring.

In addition, no matter how wonderful this natural material is, but under the influence of the weight of the log, moisture, the sun, it is crushed, and the next year, usually in spring (or early summer), it simply falls out of the cracks. And again, it is required to make a partial or complete caulking of the entire wooden house or bath.

That is, the caulk of a log house of a wooden house must be produced annually, or at least once every two years!

And do not forget, before using the moss collected in the swamp, it must be dried! When drying, the moss loses part of its volume, so it needs to be harvested with some margin.

The caulking of a wooden house or log house must be done simultaneously from 4 sides, (as if by encircling rings), which will avoid the distortion of the entire log house. Having done this work outside the house, continue caulk a log house from within.

The cost of caulking

The service of professional seaming and with the use of this modern material meets your expectations - DONE AND FORGET!

In the section you will find examples (photos) on the insulation of houses and baths.

Drafts and dampness will disappear forever in your house.

Look and answer this question: Are you ready to do this, and maybe more than once?

Any person dreams of living in comfortable conditions, the list of which includes a well-maintained 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 timber houses. How to properly caulk a house so that in the future you do not have to redo the erected creation? The answer to this question is trying to find a large number of private developers.

The caulk of a house made of timber is necessary for its insulation.

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

Despite this point of view, profiled beams are central to the ranking of building materials, and they also have a nice price. Any beam is a wooden base with all its inherent characteristics. It can dry out if a material of natural moisture content is chosen for construction.

Despite the fact that insulation can be laid between the logs, this will not save 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 caulk the log house, the warmed air from the room will be on the street. Timely work will exclude the occurrence of dampness on the walls and rotting of the surface.

Necessary tools for work

Tools for caulking log house.

Do I need to caulk a house from a bar? Yes, it is necessary to do this, because a properly carried out process will eliminate the gaps in the space between the timber and at the connection points of the crowns, the heat will be stored in the room, there will be no drafts and icing.

The material used for caulking must meet certain requirements. In terms of quality, it should be similar to a tree and have a clean, from an environmental point of view, base. Such raw materials do not tend to change 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. In such material there should be no rot or pests. 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, swamp moss-sphagnum, flax tow, and hemp hemp have long been used. Modern achievements in the construction industry have provided a new material for mass use, jute. One of the best options is swamp moss, which reliably protects the walls of the building from putrefactive processes and fungal manifestations.

Types of caulking.

As a result, buildings last much longer. Moss is able to actively absorb moisture, and if necessary, it saturates the wood with it. Its base perfectly passes air, has antiseptic properties. Moss can be attributed to the perfect materials for caulking. However, it is quite difficult to finish them with seams in a log house. Yes, and to collect such raw materials in the right amount is not easy.

Linen 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 disadvantage of such materials will be the residue in the form of a fire, it begins to crumble over time, and it becomes necessary to carry out 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 kind of materials, providing it with a special strength, hygroscopicity, and excellent air conduction. Jute is not able to rot, become moldy, its strong base does not allow birds to pull fibers out of the cracks, which is often observed when using tow and hemp.

Jute is sold in ribbons and fibers. The first form creates comfortable conditions for determining them in the space between the crowns in the log house. Pure jute fiber helps in the construction of a uniform seal. But such material will have a rather high price. To reduce its cost, flax becomes an integral component of jute, which does not have the best effect on its quality indicators.

Technological features of building caulking

Caulk technology.

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 sealing holes in a structure is not as easy as it seems. 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 erected from a material with a natural degree of moisture allows you to increase these figures to 10-15 cm. When constructing a building from a profiled beam, an insulating layer is placed in the space of spikes and grooves.

It happens that the beam connection resembles a combination in a log house, their lower part has a relief plane, and the opposite 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.

The difference between caulking timber and logs.

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’s good if they start working in four, that is, each of the walls is engaged in workers. In this case, you don’t have to worry about the skew of the building, on the contrary, its height may increase slightly, up to 15 cm. In order to carry out this process in a coordinated and organized manner, they use for work:

• caulk;
• ordinary knife;
• spatulas.

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

Options for caulking a house from a bar

Caulking methods.

Such measures 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 “stretch” technique here. Thanks to it, the insulating fibers are placed along the opening, after which they are hammered inside with the help of a caulk. Thus, it should be continued until the gap finally disappears.

The presence between the seams of large gaps gives rise to the use of the "in 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 filled. To check the quality of the work, you must use a kitchen knife, which must be inserted into the slot.

With its penetration into the gap by 1.5 cm or less, we can talk about the good quality of the insulation. With deep penetration of this item, you need to add another layer of insulating material. In the process of work, care should be taken: excessively applied efforts can lead to 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 filling cracks with insulating materials is not as simple as it seems at first glance. Efforts for high-quality work should be made maximum, layers should be hammered 3 times: first at the time of construction, then 1 year later and after the completion of the natural shrinkage process. The time period of caulking can stretch for 5 years.

These measures must be carried out on time, which will protect against drafts, condensation and wood decay. Qualitatively carried out work contributes to good sealing of the seams and the complete absence of cracks in the walls.

Round log cabins are in great demand. These building materials hold heat well in the room, have a pleasant appearance, and are environmentally friendly, created from natural material - wood. Thanks to the perfectly even shape of rounded logs, many people think that they do not need to worry about insulating their houses. In fact, this is not so, because it is impossible to lay the crowns on top of each other so that there are no gaps between them. Even if there are minor gaps, they will turn out, in the future, after the shrinkage of the house, they will become even larger, and heat will come out through them. It is necessary to insulate the cracks with the help of insulating materials immediately during construction and after using caulking.

The process of caulking is the driving of insulating material into the intervention gaps. It needs to be done several times:

• immediately after construction;
• a year or 1.5 after shrinkage of the house;
• 5 years after construction.

For houses made of rounded logs, one caulk produced after shrinkage of the log house is enough. This process well insulates the seams between the logs, prevents the penetration of cold into the room, the ingress of moisture and freezing of the interventional joints. The main thing is to properly insulate the house and use only high-quality insulation materials.

Materials for caulking

There are many materials for warming wooden houses with caulking. All of them can be divided into two main types:

1. artificial heaters. They are made from mineral, synthetic components.
2. Natural interventional heaters. They are made from natural materials, plant fibers.

Artificial materials include:

1. Mineral wool, glass wool and other fibrous mineral wool insulation. They are environmentally friendly, but still can lead to the development of allergic reactions in residents. They insulate well, rodents do not start in them. But these heaters are not hygroscopic and even afraid of moisture, it worsens their main characteristics.
2. Foamed polyethylene and other closed-cell insulation. Materials from it well insulate the interventional seam. They don't let in the cold, they don't let out the heat. But at the same time, they don't breathe. They can be compared with a plastic bag, creating a greenhouse effect in the intervention joint, this can lead to damage to the wooden material, its decay.
3. Foam rubber and other open-pore insulation materials. These heaters are not able to protect the interventional seam from freezing. Despite the fact that air and moisture are able to penetrate into the small pores of the material, they are compressed under the weight of the upper rims of the log house, and as a result, a non-breathing homogeneous mass of insulation is obtained.

Many artificial insulation materials do a good job with their thermal insulation tasks. But it is desirable to use them for structures built from bricks, concrete, cinder block and other mineral building materials. These heaters are not suitable for wood, they will shorten its life, worsening its strength characteristics.

Natural interventional insulation materials include:

1. Moss. This is the best insulator. It was used for caulking a hundred years ago. It does a great job of insulating your home. It has good hygroscopicity, it is able to absorb moisture with a volume of more than 20 times its own size. The structure of the moss fibers contains lignin, which prevents rotting and damage to the insulation material and the logs themselves. It has bactericidal properties, will destroy the bacteria in the room in the air.
2. Jute. It resembles moss in its properties, but it is easier to work with it. The density of jute is good, does not let heat and cold through. This material breathes, is hygroscopic. The appearance is also different, jute has a golden color, similar to the shade of wood. In interventional seams it looks beautiful and aesthetically pleasing.
3. Linen. This is a cheaper material, but its properties are worse. He is afraid of constant contact with moisture, which can lead to rotting. The shade of this material is grey. The density is not large, linen is softer to the touch. It is advisable to use this insulating material for insulating houses built from dry wood; it is perfect for glued laminated timber.
4. Lnovatin. Good insulation is made from jute and linen. These two materials together create an excellent insulation, which includes their positive qualities. Lnovatin is resistant to external influences, with good density and the ability to restore its dimensions. If the wooden material dries out, this insulation fills all the voids in the mezhventsovy space of the rounded log.

The process of caulking is not easy. It is best not to do it alone. Insulation material must be started from the lower interventional seams and gradually rise higher. Caulking must be done around the entire perimeter of the house at once, and not first completely insulate one wall, and then move on to another, otherwise the walls may squint, or even slip off the fastener, for example, a dowel.

For caulking a wooden house made of logs, it is best to use natural materials. They complement the wood material, improving rather than worsening its performance. If there is no experience with insulating materials, and caulking cannot be handled, you can use an alternative method of insulation - sealing.

Sealing seams

Sealing seams is easier and faster than caulking with sealants. It is easier to work with them than with insulating interventional materials. The hermetic formulations of the Neomid company have proven themselves well: Word Professional and Word Professional plus. These products are very similar to each other, but only the second sealant is more elastic and can be applied to surfaces with a large angle of inclination. Otherwise, they are no different.

Neomid sealants have good adhesion, excellent adhesion to wood material and excellent elasticity. Sealed compounds are applied with a construction gun. The hermetic seam is not afraid of weathering, moisture, does not turn yellow under the influence of sunlight, mold fungi do not form on it.
