How to caulk a log house yourself. How to make a log house caulk - materials and methods for sealing seams. Material for caulking

Now the fashion for the construction of baths and residential buildings from natural wood has revived. Log cabins have a respectable appearance, are warm and environmentally friendly, which is very much appreciated by modern people. But even such reliable and energy-saving buildings should be additionally insulated in order to feel truly comfortable in them in any weather.

Caulker - what kind of operation?

Since ancient times in Russia, most of the buildings were built of logs. Such buildings have always been called log cabins. AT last years interest in them has increased significantly, due to the special operational properties wooden houses and baths. The construction of log cabins these days is offered by many companies. And experienced home craftsmen build cozy dwellings and hot steam rooms from logs with their own hands. In this article, we will not describe the technology of building eco-friendly buildings, but will talk about how to make them warmer. Let's talk about the rules of caulking wooden structures. Without this operation, we will not be able to equip a really cozy sauna or a residential building, believe me.

First, let's figure out why you need to caulk a log house? Everything is simple here. During installation, gaps and voids remain between the logs from which this or that structure is built. It is clear that they cannot be left behind. Indeed, through such small, at first glance, gaps, precious heat will leave the room. Instead of comfortable building we will get a bathhouse or a house blown by all the winds. Solve this problem and allows caulking. It is understood as the procedure for carefully sealing all the cracks between the logs with the help of special tools and materials. All of their varieties will be described below.

Tools for warming log cabins - unusual, but easy to use

Caulking of any log house can be done independently. To do this, you will need to study the technology of the operation and stock up on a special tool:

  1. 1. Flat blade made of hard wood or metal. We need to purchase a tool with a blade about 5.5 mm thick and 10 cm wide. Such a blade, called a flat caulk, is the main device for warming log buildings.
  2. 2. A triangular tool, called a road builder, with a blade 8–15 mm thick and at least 17 cm wide, along which a special groove is made. This caulk is needed to form even rollers from the strands of the used sealing material.
  3. 3. The so-called crooked caulk - a flat chisel. The thickness of its working part is 5 mm, the width is about 5.5 cm. The chisel makes it possible to seal the seams on the rounded parts and in the corners of the log structure.
  4. 4. Wooden hammer (mallet). With it, you can easily stuff the seal without worrying that it will deform or collapse. It is allowed to work with ordinary hammers.

In addition, you need to buy two split caulks - narrow and wide. The width of such devices, visually resembling a wedge, should be approximately 3.5 cm. Breaking tools are needed to widen narrow gaps. After their use, the insulating material is much easier to place in gaps and voids.

The working parts of all these tools must be as smooth as possible, and the ends must not be sharp.

The rough surface will not allow you to perform the planned work with high quality, as the insulation fibers will cling to the caulk and stretch out of the gaps. And too sharp blades will cut the material used for the thermal insulation of the log house.

We add that you do not need to be afraid of unfamiliar names. A tool for caulking can be used by every self-taught master.

Caulking materials – range for every taste

Thermal insulation of log cabins is carried out different heaters(they, by the way, are usually called mezhventsovye), both traditional and more modern. Most known material for caulking - moss. It can be white and red. Our ancestors used it in the construction of buildings from logs. Moss is environmentally friendly natural material. He possesses:

  • low thermal conductivity;
  • antimicrobial and antiseptic properties;
  • resistance to temperature extremes (this is especially important if we insulate the bath);
  • durability.

It is almost impossible to buy moss in construction stores. Therefore, if you plan to use it, you will have to take care of the collection and proper preparation this material. Here you need to know the following. It is desirable to collect moss in November. At this time, there are practically no insects and snails in it. We carefully sort the collected material, throw out rotten particles, remove debris and lumps of soil. After that, dry the moss. Don't overdo it. Overdried moss cannot be used, it becomes too brittle. It is almost impossible to put it in the gap between the crowns and place it tightly there.

An alternative to moss is tow. It is made from flax fibers. Such material can be tape (roll) or bale. Experts recommend using the first type of tow. Insulation in the form of a tape is easier to push into the seams. Yes, and the heat-shielding properties of rolled products are higher. Bale tow is cheaper. But it is characterized by hard and short fibers. It is very inconvenient to work with such material. Key advantages of tow - not electrified, low thermal conductivity, affordable price, antibacterial. Disadvantages of the material - the insulated seam has an unaesthetic appearance, the laying process is complex and laborious. For these reasons, home craftsmen rarely use tow.

About 10–15 years ago, log cabins were often insulated with natural felt. It is environmentally friendly, easy to use, protects the building from street noise and odors, and has increased vapor permeability. But, unfortunately, this material has two serious disadvantages. Firstly, the moth loves him very much. She literally gnaws out the insulation. Secondly, felt is prone to rotting.

These shortcomings are deprived of jute - malleable, soft material in the form of tapes and ropes of different thicknesses. It can be matched to any seam. Jute, according to experts, creates an optimal microclimate in the log house. And most importantly - it is quite simple to mount it in the gap between the logs.

If a log house is built by professionals from an ordinary log or from rounded logs, has a semicircular groove and gaps of small thickness, it is allowed to insulate it with a sealant. This is the most modern and easiest way to insulate wooden buildings. The sealant cannot be used in the presence of large gaps and in cases where the grooves of the structure are in the shape of a triangle. In such situations, there will be no sense from him.

We will protect the wooden building from the cold and winds ourselves

Caulking of a bathhouse or a residential building made of logs is carried out twice. For the first time, insulation is carried out directly during the construction of the log house. We need to lay the selected material after the installation of each of its crowns. If we use insulation in the form of a tape, the operation takes place with minimal cost time. We roll out the insulation along the crown, fix it with a construction stapler (staples). If it is necessary to lay an additional tape, we mount it on the previous one with a 5 cm overlap. We cover the installed material with the next crown and repeat the procedure.

If moss is used, you will have to tinker longer. We take a bunch of dried material (moisten if necessary), lay it across the log. The fibers should hang 5-6 cm from each side of the log. Then, close to the first, we lay the second beam. We make a layer of moss quite impressive. The tree should not be visible through it. The thicker the layer, the better the insulation will be.

We carry out the second part of caulking after the installation of all the crowns of the structure and the installation of a roof on it. Re-insulation is needed for any structure, whether it is a residential building or a bathhouse. The scheme of wall insulation is as follows:

  1. 1. We take a bunch of tow (moss, felt), apply it to the seam between the logs, press the fibers into the gap with a caulking blade. We start work from the end of the building from the bottom row.
  2. 2. Carefully twist the protruding ends of the material. We will get a roller 8-10 cm long. It should be applied to the gap and again pushed between the logs using a caulk, leaving only a small tip.
  3. 3. Weave the next bundle of material into the free end and continue to insulate the log house. The roller cannot be interrupted. It must remain intact along the entire length of the gap.

It will take a lot of time to complete such a laborious operation. But on the other hand, we will get a well-sealed building. And you can reduce labor costs by using not tow or moss, but tape materials. Mounting them is much faster and easier. We simply cut off the piece of tape required in length and proceed to driving it into the seams. After the walls are insulated, we proceed to the thermal insulation of the corners of the log house. This operation is also easier to perform with tapes. They are pushed into the gaps with a crooked caulk.

Caulking with sealant is allowed after complete shrinkage of the structure. The procedure for performing such work is given below:

  1. 1. Well clean the seams between the crowns of debris and dust, wipe them with a dry cloth.
  2. 2. We treat all joints with a primer (water-based or rubber-based primer), using a spray gun or an ordinary brush.
  3. 3. We are waiting for the soil to dry.
  4. 4. We put a tourniquet made of polyethylene (foamed) into the gaps. We select products corresponding to the width of the seams.
  5. 5. Apply sealant.

To give the log house an elegant look, we process the insulated joints with tinted or colorless varnish.

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

Considered one of the best materials for a caulk. 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, roll material 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 heater is easy to use, durable, due to a large number natural resin, it does not form mold and microorganisms. Even with 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 view, 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 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.

In order to get a perfectly warm frame for permanent residence, it is not enough to properly mount it. It is also necessary to fill all the gaps between the logs with high quality, so that heat losses overcome the house as little as possible. Not everyone knows how to properly caulk a log house, and therefore the performance of insulation work sometimes leads to a distortion of the house (in the worst case) or simply to rotting of wood and insulation (at best).

About how to properly caulk log cabins from moss video and general recommendations on other types of insulation in our material below.

Materials for caulking a log house

You can caulk a wooden frame various materials. Fortunately, the construction market today offers a wide selection of them from natural to synthetic and semi-synthetic. The most popular are the following types:

  • building moss. May be called "sphagnum" or "cuckoo flax". This type of insulation was used by architects back in ancient Russia. The qualities of moss as a heater are priceless and undeniable. Sphagnum is highly resistant to moisture. It seems to shrink with the tree in case of waterlogging of the latter and simply takes all the moisture into itself. In addition, moss is of no interest to birds, moths and other insects. And this means that all the material for the caulking will remain in the place that the master determines for him. Moss "sphagnum" and "cuckoo flax" does not burn, does not rot and is an excellent natural antiseptic for wood for many years.

Important: you can buy building moss in any volume at specialized points of sale.

  • Construction tow. This type of material also works well in tandem with wood when caulking walls. Produce tow from the remnants of flax and hemp grass. Tow is also a natural material that protects wood from moisture and cold.
  • jute fiber in the form of a tape - advanced natural-type materials for caulking walls. Jute is made from a shrub that belongs to the linden family. And linden, as you know, copes well with cold and moisture. Jute is able to somewhat moisten the log when it dries out excessively, but it does not take moisture from the tree when the humidity in the house is 80%. It is convenient to lay a jute tape between the crowns, and also stuff it into the cracks when re-insulating the house.
  • Lnovatin. They produce insulation from flax fiber in the form of a wide tape. By their own technical specifications lnovatin is similar to jute. It is convenient in laying between the crowns and when caulking "in a stretch".
  • Felt. Unsuccessful type of insulation for a wooden house. Felt is prone to rotting between logs, and if excessive moisture gets on the walls, the felt will not only lose its insulating qualities, but also spoil the tree from the inside.

Tool to get the job done

To properly caulk a log house, you need to use special tools. Otherwise, the insulation will lie superficially in the cracks, which will lead to the formation of cold bridges. Most professionals use special caulks made of steel or metal. The first one is better. Can also be made wooden caulks from dense breeds of a tree - a beech, a nut, an oak. At the same time, it is desirable that the tool has a rubberized handle for ease of work.

Important: the caulking tool should not have a sharp blade, otherwise the insulation may be damaged during caulking. For the same reason, you should avoid notches on the surface of the tool. The insulation in this case clings to the teeth and breaks.

The main type of tools for caulking:

  • Stacked caulk. It is a flat kind of chisel with a blade width of 10x0.6 cm. It is used for stuffing seams between logs with insulation.
  • Crooked caulk. The same chisel, but curved. It is used for caulking the corners of the house and rounded cracks. The width of the blade in this case is half that of a type-setting caulk.
  • Caulker "Roader". It has a fork-shaped shape and is used for caulking cracks using the “stretching” method. The blade here has parameters of 170x15 mm. Depending on the width of the gap, you can use a wide, medium or narrow caulk.
  • The caulk is broken. It has a wedge-shaped blade 30-35 mm wide. Such a tool is used to expand narrow gaps and fill them with insulation.
  • A mallet is used to help all types of tools. With the help of such a rubber hammer, the seal is pushed into the slots.

Work performance technology

In order for a log house to be insulated with high quality, the insulation must be laid in several stages. First, roll insulation or building moss is laid out between the crowns in such a way that it protrudes 5-6 cm beyond the edges of the log. In this case, a tape insulation such as jute or flax fiber is fixed to the tree with a construction stapler. By the way, you can do the same with moss.

After the house settles and sits down, new cracks form. It is through them that heat loss will occur. In addition, the heat leaving the house, in contact with wood and low temperatures on the street will form perspiration (moisture). That, in turn, is transformed into frost, which will destroy the log. That is why additional caulking of new slots and packing of a peeking seal between the crowns is required.

The third caulk can be done after 2-3 years, when the house is completely seated and all possible cracks will be open to the master.

Caulking methods

Warming "stretching"

This method involves filling narrow cracks and gaps. It is good for caulking houses from rounded logs, since the gaps here are minimal. At the same time, you should be careful with the caulk of such a log house. There is a risk of overfilling the slots, which will lead to distortion of the crowns, and, accordingly, the walls.

So, stretching insulation is performed in this way:

  • As soon as the edge of the insulation 5 cm long remains, a new bundle of insulation is taken and its edge is woven with the remaining end.
  • The resulting plexus is hammered into the slot and in this way they continue to caulk all the gaps.

Important: the quality of the caulk can be checked by pulling on the remaining end of the insulation. If the material comes out freely from the gap, the job has not been done correctly. If the insulation remains in the gap, then everything is done soundly.

Caulker "in a set"

This method is used to fill large gaps. Here it is necessary to wind the insulation into a skein. Then, loops are made from the resulting fiber and the slots are stuffed with them. And first they caulk upper part gap with a stuffing tool, and then hammer the loops into the bottom of the gap using the road builder tool. It is worth knowing that the thickness of the insulation loop must correspond to the thickness of the existing gap in the log house.

Important: when working with a mallet, it is worth remembering that there should be one hammer blow per blade width. Do not be too zealous, otherwise there is a risk of overfilling the cracks, which will lead to a warp of the house.

There is also a number general requirements, which should be observed when caulking a log house. By following them, you can avoid blunders in work:

  • So, you need to start re-caulking at home from the lower rims, because when you stuff the insulation in the crack, the house will rise by 5-15 cm.
  • It is necessary to fill the gaps alternately from the outside and from the inside of the house. That is, first they fill the slot of the lower crown from the outside, and then they go inside the log house and fill the gaps of the same crown from the inside. This technology will help maintain the evenness of the walls of the house.
  • It is best to use natural heaters for caulking. Synthetics blocks the breath of the tree.
  • If moss is used for caulking, then it should be treated with a special solution of soap and oil in a ratio of 200:500, mixed with a bucket of water.
  • Warming of the house must be carried out in dry weather at a temperature of + 10- + 20 degrees Celsius.
  • In addition, a lack of insulation is just as bad as its bust. It is necessary to strictly monitor the amount of fiber in the loops so that their width matches the width of the gaps.

Remember, properly done work is the guarantor of a warm and comfortable home even in severe frosts.

Even if all stages of the construction of a wooden structure are completed professionally, this does not guarantee that there will be no drafts in the house. Firstly, the used blanks (beam, log), characterized by a large length, cannot be adjusted to one another with jewelry accuracy. Secondly, wood is constantly in the process of deformation (under the influence of moisture, temperature, and also due to natural shrinkage).

Even interventional insulation is not able to level the problem of emerging cracks, gaps; only caulking, as a way of additional thermal insulation of the log house. It is quite doable with your own hands, if you know how to do it and what you may need in the process of work.

Caulking is not a one-time event. For the first time, it is carried out either immediately after the completion of construction, or in parallel with the construction of the log house. Secondary - the next year or after 2 - 3, depending on local specifics (climate in the region; location of the building on the territory; its protection from winds; grade of wood used, which determines the intensity of its shrinkage and a number of other factors). The third time - after the final moisture removal from the material. As a rule, 5 years are allotted for this. But this does not exclude the need for unplanned caulking, as cracks form in certain areas.

Any material that can close the gap is not suitable for these purposes. His choice is determined by the following criteria:

  • optimal combination of elasticity and density;
  • low thermal conductivity;
  • resistance to destruction by microorganisms;
  • hygroscopicity, approximately identical to this indicator of wood. That is, the material for caulking should be characterized by the ability to equally absorb moisture and give it away;
  • "ecological cleanliness";
  • resistance to external negative factors. That is, the caulk should not be deformed, much less destroyed under the influence of the atmosphere (changes in humidity, temperature, their limit values).

When insulating a log house, it is necessary to adhere to a certain scheme. Caulking is carried out in levels, along the perimeter of the building. It starts from the lower crown, and only after high-quality sealing of the 1st aisle, you should start processing the 2nd. Failure to comply with this recommendation leads to the fact that under certain conditions there is a risk of warping the log house.

The specifics of caulking of timber and log buildings are somewhat different. The figure explains this well.

Caulking is always carried out before the start of any work on the finishing (plating) of the building. When insulating, the material is forced into the gaps with force, which leads to the "rise" of the entire log house. In total expression for one-story house- about 10 cm.

Cannot be used when caulking different materials. The reason is the differences in hygroscopicity, which determines the degree of deformation when liquid is absorbed. Caulking only on one or two sides is also not recommended. Failure to comply with these requirements leads to a distortion of the structure.

If this happens, it is not critical. You can fix the skew with an additional caulk. The main thing is to correctly determine the area where the secondary installation of insulation will eliminate this defect.

There are quite a few of them. You do not need to be an expert in the field of construction to understand that natural materials are the best.

Moss

It has practically the same advantages. You can not purchase it, but assemble and prepare it yourself, although this opportunity is not available to everyone. "Ecological cleanliness" a priori no doubt. Another significant advantage - moss has antibacterial properties. Therefore, in places of sealing cracks, it provides high-quality protection of lumber from fungi and mold. Experts note only one drawback - the high cost of purchased moss.

Tow

With it, on the contrary, the cost is low, but it is difficult to work with this material, and it does not differ in durability. Firstly, the tow is fibrous in its structure, and therefore it absorbs moisture very actively. And she gradually moves to the tree. This, in turn, complicates the removal of rotten insulation from the gaps, especially if the seal was made to a great depth (which is typical for log cabins). Another disadvantage is that moths are very fond of tow, which gradually spreads throughout the house. And the quality of thermal insulation when the layer is damaged quickly decreases.

Lnovatin

Quite a new type of insulation. Represents the tape received by a method of pressing of the crushed flax. The material is good (heat-saving indicators are high, it does not absorb moisture and is not subject to decay), but it is only suitable for sealing large gaps.

Jute

The main characteristics are identical to flax wool. The advantage is in the variety of assortment. Jute is produced in ribbons or cords, so this material can be considered universal. The high price is the only drawback of the product.

Sealing compounds

They are categorized into three groups, but the common characteristic is the simplicity of warming the log house. The use of these heat insulators does not require professional skills; besides, the time savings are quite tangible.

Pasta in tubes. It is easy to pick it up to match the wood, so when sealing small gaps, it - the best way caulks. If necessary, this place is varnished.

Briquettes. Their use requires a special gun. Convenience in a variety of nozzles, which allows you to process cracks, both large and relatively small.

Cords, plaits from polyethylene foam. They are pressed into the gap with the help of special tools. It is advisable to use for sealing cracks of great length.

Instruments

Since caulking is carried out in various areas that differ in the parameters of the cracks, and hence the complexity of the operations, it is advisable to use a set (set) of devices for such work. Insulating a log house with just one will not work. The tool will not be needed only in the case of using soft (paste-like) sealants.

A properly selected tool will allow not only to optimize work in various areas, but also to expand (if necessary) the gap, to insulate the place of the log house, which has a complex geometry. Therefore, you should not be limited only to the devices shown in the figures.

Basic caulking technologies

Stretching

As a rule, this method is implemented in areas characterized by a large length. Accordingly, the material is also selected - cords, ribbons, harnesses. The meaning of the operation is to uniformly push the insulation into the slot with a gradual displacement of the working surface of the tool to the side. The peculiarity is that a small part of the material remains outside the log house. On the last step the excess is tucked up (that is, a kind of roller is formed) and driven into the gap with effort. This ensures its complete sealing.

To the set

This technology is suitable for large gaps, since in this case a narrow tape (cord) cannot provide high-quality insulation. Or at difficult areas when the slot width changes many times. The material is disassembled into separate strands; they are twisted (in balls, loops) and driven into the gap. Working is more painstaking, requiring time and accuracy.

Sometimes the edges of the interventional insulation protrude somewhat from the log house. Experienced craftsmen do just that during the installation of the structure, taking into account its subsequent shrinkage. In this case, it remains only to tuck the excess and drive them into the gap.

In principle, there is nothing complicated in the caulking of a log house. It is only necessary to correctly assess the specifics of the work, the parameters of the slots and choose the right material and best way thermal insulation.

The caulk of a wooden house is an important step in warming the finished building using natural or synthetic heat insulators. Here, every detail matters: the right working tool, high-quality insulation material, work performance technology. Not all homeowners are aware of how to correctly seal interventional gaps and joints in order to reduce possible heat loss, avoid distortion of the house structure, and prevent rotting of wood and heat insulator.

What is the caulking of the log house for?

Thermal insulation of a log house contributes to the preservation of heat in the premises, prevents the deformation of wood and a decrease in its operational parameters. Modern heaters are durable, practical and safe, therefore they provide high-quality caulking of wooden buildings.

Caulker felling solves the following tasks:

  • eliminates cold bridges and reduces heat loss at home;
  • corrects structural defects in the structure;
  • eliminates various flaws in the external and inside corners, crowns, openings of doors and windows;
  • makes the house more attractive and reliable;
  • increases the life of wood.

When is the caulking

The caulking of a wooden house is carried out in several stages, and this is due to the gradual shrinkage of the wood. Maximum shrinkage occurs during the first 18 months after the end construction works and terminated after 5 years.

  1. The first stage of caulking is performed after the assembly of the log structure. In this case, when building a house thermal insulation material fills the space between the logs so that the edges hang freely on both sides. After installation roof structure the insulation is hammered into the connecting seams between the crowns.
  2. The second stage of insulation is carried out 1.5 years after the completion of construction work and preliminary shrinkage of the house. The insulating material is laid tightly enough to hide all the gaps and cracks.
  3. The third stage of caulking is carried out after 5 years, when the shrinkage process of the log house is considered to be fully completed. All existing defects between the logs are filled with insulation.

Important! For a log house, all three caulking is carried out, and for a house made of timber, which will be lined with siding on the outside, the third stage of caulking is optional.

Materials for caulking

For caulking timber or logs, it is better to use natural heaters with the following characteristics:

  • hygroscopicity,
  • resistance to temperature changes,
  • breathability,
  • environmental Safety,
  • ease of installation.

These heaters include:

  • moss (red and white),
  • tow,
  • lnovatin,
  • jute.

Moss

The safest and most practical material with excellent antiseptic properties. It provides reliable protection of wood from rotting and biological damage.

Moss (sphagnum) is a reliable material for sealing interventional joints: it passes air well and quickly absorbs excess moisture, prevents the development of pathogenic microorganisms and fungi, and as a result increases the service life of wood.

Moss is resistant to fire and decay, therefore it is able to maintain its performance characteristics for a long time. High cost is the only drawback of such material.

Self-procurement of raw materials will significantly reduce the cost of thermal insulation of a house made of logs or timber.

Before caulking the walls, the pre-treated moss must have a suitable moisture level - not excessively dry or wet.

Tow

A practical and safe material that is used for caulking crowns after complete shrinkage of the log house. It is made from hemp, jute and linen fibers.

Sold in pressed bales or rolls. Tow in bales has short and stiff fibers, which complicate the process of driving interventional seams. High quality tape tow has long, elastic and soft fibers.

This material has low antiseptic properties, is susceptible to high moisture, and therefore requires additional treatment with protective impregnations or paints.

The main disadvantages of the insulation include the complexity of laying, the unattractive appearance of the treated seams, and the short service life.

Lnovatin

A natural material for caulking wooden houses, which is produced by pressing short flax fibers into ribbons. Lnovatin has high heat-insulating and moisture resistant characteristics. Such insulation is able to provide reliable protection of wood from rotting and mold damage.

Lnovatin is used for sealing seams between crowns with fixation on metal staples.

Jute

The most high-quality and durable tape insulation for caulking houses made of logs or timber. The material has high heat-saving properties, is not susceptible to rotting and mold damage. Even with prolonged exposure to moisture, jute fiber remains almost dry.

Jute is used for primary and secondary thermal insulation of the house. It has high strength, wear resistance, elasticity and practicality. It fits into interventional seams with fixation on staples.

The only drawback of the material is its high cost.

Caulking tools

If natural materials are used for thermal insulation of a wooden house, then before caulking, prepare:

  1. Kiyanku. A small wooden or rubber mallet for laying insulation with wooden caulks.
  2. A dial-up caulk. Spatula with metal or wooden base, blade width 10 cm, thickness 0.5 cm. This is the main tool for caulking log crowns.
  3. Crooked caulk. Curved chisel with a flat blade 5 cm wide and 0.5 cm thick. Used to fill fillet joints and gaps in rounded sections of a building with insulation.
  4. Road builder. Triangular blade with a special longitudinal groove. Blade width - 17 cm, thickness - from 0.8 to 1.5 cm. The tool is designed to fill gaps of equal width.
  5. Breaker caulk. A narrowed wedge-shaped blade up to 3.5 cm wide, which allows you to widen the intervention gaps for the convenience of laying heat-insulating material.

Important! All caulk blades should be slightly dull and smooth to avoid damaging the wood and pulling the insulation out of the seams. Before starting work, the tools are thoroughly cleaned with a clean cloth.

Logging caulking technology

The process of caulking a house from a log house is carried out in stages. There are two caulking methods:

  • in stretching
  • into a set.

It doesn’t matter what method the caulking is carried out at home, all insulation work begins with the lower crown. Next, we will consider how to competently caulk a wooden structure.

Stretching

Stretched caulk provides for the insulation of the seams between the logs with pre-stretched heaters. For this, fibrous and rolled materials are used.

Fibrous insulation

  1. Work is carried out from the ends of the lower crown. A small part of the insulation (for example, tow or moss) is applied with transverse fibers to the seam and clogged inward with a type-setting caulk.
  2. At the edges, the insulation is rolled up with a small roller and compacted into an interventional seam.
  3. Next, a new portion of insulation is used, which is formed into a roller, and the entire caulking procedure is repeated. This allows you to qualitatively seal the seam along its entire length.

Roll insulation

Dense rollers from roll insulation are much easier to get. For even distribution, the material is gently stretched along the entire length of the seam and applied to it across the fibers.

  1. The tape is unwound on a flat surface from one of the corners to the opposite corner.
  2. Having picked up the free edge, with the help of a caulk, the insulation is placed in the interventional seam so that the free edges hang down by 5 cm. This fills the entire length of the seam.
  3. After the seam is completely filled, the tape is cut off from the roll.
  4. The rest of the insulation is driven into large gaps between the logs. The insulated seam must have the same thickness and protrude 3 mm beyond the edges of the grooves.

To the set

Caulking in the set allows you to insulate wide and deep gaps between logs. It uses a larger volume of material, respectively, and the quality of thermal insulation is higher. Tow, hemp rope or jute cord is suitable for this.

  1. To caulk a log house with jute (the easiest option for beginners), a small amount of material is unwound and folded into loops. Next, each loop fits into the seam with a caulk.
  2. Stitching begins at the top of the seam and then continues at the bottom.
  3. On top of the laid insulation, an additional strand is applied for better insulation. The material is leveled along the entire length of the seam with the help of a road builder.

If desired, the insulation of the house in this way can be accelerated. In this case, the driving of the heat-insulating material is carried out using a perforator. The tool is used at low speed to prevent deformation of the seam. Also, a pneumatic hammer with a compressor is suitable for laying insulation.

Caulker corners

The corners in the log house are insulated after the completion of the main work.

To do this, it is better to use a roll insulation and a crooked caulk. The process is carried out as follows:

  1. The free edge of the tape insulation is applied to the seam located in the corner and clogged with a crooked caulk.
  2. After installing the material, its free edges are rolled up and hammered into the seam.
  3. All work on laying insulation is carried out from top to bottom. For uniform driving, the material is gently stretched and straightened.

decorative caulking

If the main task of caulking is the thermal insulation of a wooden structure, then decorative caulking is used to decorate insulated interventional seams.

To give the seams of the log house an attractive and harmonious appearance, experts recommend using a rope and a rope made of jute or flax as a finish.

The rope is carefully fixed to the surface of the seam on galvanized nails without hats, driven into logs at a distance of 18 cm from each other. Decorative caulking is also suitable for hiding unevenly dried joints between the crowns and for additional insulation of the structure.

After completion of the caulking process wooden house should be used as much as possible throughout the year. In winter, a check is made for the formation of new cracks and deformation of the laid insulation.

A year and a half after the first stage of caulking, the second stage is carried out. In this case, a thorough inspection of the structure is carried out, heat-insulating material is added where it has deformed or fallen out, as well as where new gaps or distortions of the log house have appeared.

Caulking a wooden house is an important and responsible event that requires a competent approach and compliance with all stages. technological process. The quality of the work performed depends on the internal microclimate in the premises and the duration of the operation of the house.
