Correct linen winding on the thread. How to wind flax on a thread: detailed instructions

How to wind flax on a pipe with your own hands: step by step instructions + Photo. In everyday life, very often it is necessary to carry out minor repair work, during which it is required to use flax for winding pipes. This may be required for a radiator or plumbing. Every master should be able to use the tow correctly, as sooner or later it will come in handy for him. can be made of plastic, metal, nylon or metal-plastic. Each type of material has its own adapters in order to connect with other pipes.

We will talk about such connections.

Since every home craftsman has at least once encountered a problem when it is required to wind flax on a thread from a tap, you should learn how to do this. If you want to tightly connect each element of the water supply and pipes, then packing should be done. To do this, two pipes must be packed at a 90 degree angle using a sleeve, and each pipe must have a thread at the end. The coupling will have an internal thread in the composition, as well as external threads. Twisting alone is not enough, so it should be tackled for the best connection.

Description of flax (tow)

Before you start winding flax on pipes, you should get a better understanding of what flax tow is. It is a fibrous type material that is used to seal threads. The product is natural, it is made from the primary processing of homogeneous, thin and long-fiber flax. The scope of the material is wide. Depending on the manufacturing method, the material is tape, jute, plumbing or construction. In our case, we will talk about insulation, which makes it possible to perform reliable sealing of each joint.

For the manufacture of such material, combed fibers are used, which are brought in bales. They are used for construction work during the sealing of seams, when insulating a log house and laying wood elements. The material is natural, and this is especially valuable among those people who are engaged in the construction of a wooden house. If rolled material was used to connect pipes with flax, then it can be called tape. Such material is also used to caulk seams in log cabins and lay crowns. The advantage of using flax is the cost, since the material for plumbing works is several times cheaper than other analogues. In addition, it is economically consumed, and although the fibers are thin, they are very strong. If wound correctly, they can be used for various types of work, where any type of connection will be used. Can be used for cast iron and ceramic pipes.

Advantages

Before you start winding flax on the thread, you should know that it begins to swell and absorb moisture, which allows you to increase the level of tightness, since there will be no way out for leakage. In addition, the material has high mechanical stability, and it is this characteristic that makes it possible to fit the plumbing, and the hermetic properties will not be lost, the connections can be turned off half a turn or a whole turn.

Disadvantages of using

If you are thinking about how to wind flax on a thread, then you should first familiarize yourself with all the shortcomings of the material. So, the material is based on a substance of organic origin, and therefore it can begin to rot under the influence of moisture and air. Also, he sometimes gets inside even during a routine examination. To do this, when using tow, you should also use another material, additional, which will help prevent the decay process. It can be a sealing paste, oil paints, grease or lithol.

Sometimes, before winding, you should first prepare the thread, since if you lay the material in a large layer, then there is a possibility of damage to the joints, and this is especially true for bronze and brass. If you are faced with the question of how to wind tow on a threaded connection, then you should remember that such a seal requires knowledge of the rules of winding.

Additional materials in combination with tow will make further disassembly difficult, and this applies to oil paint and silicone. Sometimes such additions make the editing process even unbearable. The use of flax is not suitable when the temperature reaches +90 degrees. In such places, the material begins to weld, and then completely loses its sealing properties. If you are dealing with steel, then it is imperative to follow the winding technology, as otherwise the thread may corrode.

How to wind flax onto a thread

Before you start winding, check the thread - if it is completely new, then you should prepare the threads. Most manufacturers currently produce fittings that already have threads, but with notches for winding flax. The fact is, the material begins to jump off the smooth thread, knocks into a single bundle, and this can lead to a breach of tightness. So that the fibers can catch well, you should make notches on the turns. If necessary, you can always apply them with a file, a file or a metal hacksaw. Some of the craftsmen may use a plumbing wrench or even pliers - the thread should be gripped, and then the serifs should be made with a slight movement of the hand.

The main thing is that roughness appears on the turns. Before you start winding flax on the thread, you should separate a small strand from the whole braid. Grasp enough fibers so that the winding is neither too thin nor too thick. Professionals advise to use the thickness of the material, which will be like 1 or 2 matches in a girth. If there are lumps in the strands, remove them and fine lint.

Methodology for performing work

You can apply tow using your own technology, which you like more than others. Some of the specialists twist the flax into flagella, and someone braids it into a weak pigtail, someone simply puts it in the form of loose threads. The order of application of materials such as pastes also varies. Sometimes you can first lubricate the thread, wrap it with fibers, and then apply a second layer, and someone impregnates the fibers in advance, and then everything is prepared. Both options are correct, and if you think about how to wind flax on a thread - counterclockwise or clockwise, then you should heed the advice of the masters who wind pipes with flax both clockwise and counterclockwise.

In addition, the strands need to be pinched with your fingers outside the turns, and the first turn should form a cross, which will fix the material. Do not leave gaps, stack all the turns one by one. If you are making a connection, then a lot of the material used can be squeezed out of the fitting, this happens when working with a steel coupling and an iron pipe. Brass connection can burst from strong pressure, this is important for elements made using modern technologies.

Plumbing paste or other sealing type materials should be applied around the flax, and the movements should be rotational. The work must be done very carefully. Glue the other end closer to the edge of the thread, and before direct screwing, check if the pipe hole is filled. Now you know how to wind flax onto threads, and a photo of the process can be found in the article.

But from them you will not understand that the twisting of the elements should be performed with effort, but in moderation. If the nut runs easily, then little flax has been used. Winding will be considered correct if the material does not knock out and the surface around the joint remains clean. For connections on gas pipes, it is better not to use organic tow, since under the influence of gas, the winding and silicone, which will be used as an additional material, will be destroyed. Here, the use of FUM tape will be most appropriate.

If you somehow thought about how to wind the tape on the thread of the pipe along the thread, then you can use the technology that is used when working on eco-plastic products. This material, like brass, can also burst. The main thing when twisting is not to overdo it.

Before starting work, connect both fittings and count the number of turns. Wrap flax evenly, coat its surface with additional compound, and only then can you connect the fittings. If you counted, for example, 6 turns when idling, then after winding the tape it is better to do 5.5 turns, while not reaching the end of the fitting. In this case, it will be more expedient to use packing paste instead of sealant.

Conclusion

Very often, men wonder how to wind flax on a thread. In this case, remove the old connection and carefully watch the thread. Then walk along the turns with the tip of a knife / awl to remove all accumulated debris. Use a metal brush to clean the coils before winding the tape, and do this until everything shines.

When repairing a pipeline, the main requirement is the tightness of the joints. The functionality and trouble-free operation of plumbing, heating, gas and other systems depend on them. How is tightness achieved?

Most often, when installing and repairing a water supply system, a threaded connection is used - it is inexpensive, quick and practical. With just a wrench at hand, the plumber can easily disassemble and assemble the system, replace the failed unit. But the thread does not guarantee that the connection will be perfect, some other sealing component is needed.

What seals does the building materials market offer?

There are several types of sealing materials that differ in cost, convenience and reliability of use:

• FUM tape (fluoroplastic sealing material)
• Sealing thread
• Linen thread

Among all the FUM offers, the tape is quite capricious in application, the sealing thread has good qualities, but it is too expensive, and only flax is an impeccable tool that has proven itself for many decades.

How to properly wind flax onto threads?

In order for the connection to be strong and tight, the threaded sections must be cleaned of rust using fine-grained emery paper. It is important at this stage not to damage the threads. Then you should check if there are notches on the thread - with them the laid flax threads are fixed and do not move when the parts are connected. If there are no notches, they can be applied with a file or a plumbing wrench.

Correct winding of flax consists of several steps:

• Check the tightness of the connection with a clean, flax-free thread in order to understand how thick the winding should be done.
• Take a bunch of flax and separate a strand of sufficient thickness from it to obtain a tight connection. Flax hairs should be of the same length, free of lumps, straw and debris.
• Twist a loose strand from the strand of such a thickness that it can fill one groove of the thread.
• Holding the end of the linen cord at the edge of the thread, wind it in the opposite direction of tightening the nut. Each subsequent turn should fit snugly to the previous one. It is important here not to overdo it with the number of layers, there should be no more than two of them, otherwise the connection may burst when twisted or from hot water during operation. If the bundle is short, winding should be continued with the next bundle.
• Inspect the reverse side of the winding and make sure there are no bald spots.
• On top of the flax, apply a layer of special paste or silicone and tighten the joint until the paste hardens. The use of a sealing compound contributes to the durability of the connection, prevents flax rotting, and helps to easily disassemble the structure in the future. Do not use a sealant as a seal; such a connection is difficult to disassemble.

Despite the availability of modern materials for sealing plumbing threaded connections, flax remains relevant due to its reliability, resistance to high temperatures, the possibility of adjustment and a long service life. Even against the background of all the advantages, not everyone is ready to use tow, since it is longer and more difficult to work with it, and besides this, it is possible to overdo it with its amount, from which fittings, valves or other elements burst. If you adhere to certain rules, then all this can be avoided and only positive properties can be achieved from the connection.

What is required to seal the joints with flax

Unlike anaerobic gels, it is impossible to twist the connection by hand when working with tow. In this regard, before starting work, you need to prepare:

• adjustable wrenches;
• gas keys;
• flax fibers;
• plumbing paste for the Unipak seal.

How to use flax correctly

The purpose of using flax is to seal tightly the space between the external and internal threads of the two connected elements. If you wind it right away without preparation, then it will be difficult to tighten the fittings in the future. You must first drive them dry so that the threads rub in. If you have to work with different materials, for example, a brass barrel and a cast-iron American for a circulation pump, then it is simply impossible to screw the connection manually. In this case, it is convenient to fix the keg in a vice, and if they are not there, then a gas wrench will do. The connection must be driven to the end several times so that it begins to twist and twist by hand.

After lapping the thread, you need to take a bunch of flax. Ideally, the tow is clean without straw. Its amount is based on the depth of the thread. The higher the diameter of the connected elements, the more tow will be required.

The bundle should be combed out with your hands and the fibers should be smoothed out, then start winding from the middle of the nipple.

This should be done in such a way that the flax is folded in half with a small tail. Its loop is thrown onto the thread from itself. The ponytail is wound counterclockwise.

Having driven the tail under the main whip of flax, you need to start winding the remaining long bundle of tow in a clockwise direction. It is laid with a wide tape so that each turn half falls on the old loop and partially goes out onto a clean thread.

Gradually overlapping the thread, you need to move to the edge of the fitting. If a small tail remains, you can start winding it back to the middle. Flax needs to be smoothed by turning the connection in the clamped fingers so that it tightens and does not unwind.

Now, ideally, lubricate the surface of flax with a specialized plumbing paste, which will prevent rotting and greatly increase its service life. It will act as a lubricant and ease winding. You can do without it, but only in sections of the pipeline that allow you to conveniently carry out repairs. For clarity, I am not using it in this example.

After preparing an element with an external thread, it is necessary to screw on an American, a tap, a plug, or whatever is required. If the tow is wound correctly, then after the completion of the connection, the flax practically does not protrude. It is convenient to cut off rare protruding fibers with a blade, and even easier to burn with a lighter.
We unscrew the connection.

As you can see, flax clearly sealed all thread grooves.
When using tow, if it turns out that the thread has been overtightened and this interferes with further installation, then it can be released or pulled. This connection allows up to 45 degrees of rotation in both directions. Of course, when tightening, you cannot overdo it so that the connected elements do not burst. Be sure to watch a visual and detailed video.

The question of how to wind flax on a thread arises for many people, just as often they have to face the task of choosing between fum-tape and flax. Each option is preferred for different situations. Moreover, in some cases, they can be interchangeable.

Advantages

Plumbing linen is a standard thread sealant, and can also be found under the name tow. It has many advantages, among which the following are worth noting:

• Resistance to mechanical stress. This material is the best option for sealing sanitary fittings. When using it, it becomes possible to adjust while maintaining tightness.
• In the process of getting wet, flax increases its volume. That is, you do not need to worry if a small leak occurs after the connection is completed, since it will be eliminated on its own. The material begins to swell when exposed to moisture and thus blocks the flow.
• Versatility. Correct winding allows for different types of connections.
• Low cost. Compared to other seals, this option is significantly cheaper. The main thing is to choose a high-quality winding, it should be light, be realized in the form of a bay or a pigtail, while there should be no lumps and blotches.

Peculiarities

Despite the existing advantages, it was not without some points that complicate the application:

• Care must be taken when working with bronze and brass, as the thread may be damaged when winding a thick layer.
• The threads must be carefully prepared before use. Threaded fittings for linen winding are on the market today. They can be identified by special notches. If they are not available, you can use pliers or a file. The notches prevent flax from churning and slipping.
• Before winding flax on the thread, it must be treated with suitable compounds - this can be oil-based paint, silicone, sealant or grease. Since this winding is an organic material, it is susceptible to the development of putrefactive processes in contact with water and air. The latter is annually found in heating and water supply systems in the course of preventive maintenance or repairs. Special formulations prevent material degradation.

Processing facilities

Some special compounds can complicate the dismantling of connections, the need for which arises when a leak occurs, when new elements are connected, or in the process of replacing some parts. Paint and silicone contribute to the adhesion of the elements and, as a result, make it difficult to separate, in some cases it becomes impossible. In the absence of accompanying means or illiterate winding on steel parts, similar problems appear, caused by the occurrence of corrosion damage on the joint.

Linseed tow should be wound only in accordance with the established rules. To begin with, it is processed with a suitable tool, and the thread for it is also prepared. The winding direction must follow the threads. Further, the remaining part is taken out of its limits and stretched, at this time the connection is wound and tightened. How much flax to wind on the thread? This can be determined by the tightness of the fitting on it.

Which is better: flax or fum tape?

Special requirements are imposed on the materials used for organizing hot water supply. They also apply to the means used for reeling. Due to the high temperature of the liquid in the pipes, the rewinding must have high tightness and resistance to temperature effects. Linen meets these requirements, while fum tape is not the best material. When bonded, it splits into multiple fibers, sealing voids and preventing water leakage. The high temperatures inherent in hot water piping and heating systems cause the fibers to shrink. This increases the risk of leakage.

As for other characteristics, it should be noted that linseed tow is cheaper than fum tape, even if the material is used for processing. If in small jobs the difference is not so noticeable, then with active use you can get significant savings. But at the same time, the tape speeds up the work. Thus, it is impossible to say unequivocally which is better: flax or fum tape, since each material is suitable for different tasks.

Combination of two materials

In some cases, a combination of flax and fum tape is used to obtain a better connection. There are two options: flax is covered with several turns of tape, or both materials are wound in turn. Despite its effectiveness, this method has not become widespread due to the peculiarities of the winding conditions.

Preparatory work

Before winding the flax onto the thread, the connection is prepared. This is to prevent the material from knocking or sliding off the level surface. If the flax does not hold in place, the degree of sealing will be extremely low. To fix the fibers, special notches are applied on the turns. They can be cut with a metal hacksaw, file or file.

How to rewind the thread correctly?

In the absence of such tools, you can use pliers and, grasping the thread as tightly as possible, squeeze it - you should get small notches in a circle of turns. Also, as mentioned earlier, you can purchase fittings that are specially made for plumbing tow.

How to wind flax on a thread: instructions

The fibers are separated by small strands. It is worth noting the need for careful selection of the thickness of the strands, since the winding should have an average thickness. If any lumps or foreign elements are found, they must be removed. Plumbers use various options, for example, rolling up a loose strand or braided. This is necessary to simplify the work, while the quality of the connection remains unchanged.

Next, sanitary flax, pre-treated with a special compound, is wound on the thread. You can also first apply the composition to the surface, then wind the material, and distribute an additional layer on top. The effectiveness of both options is on the same level.

Regardless of the method used, the tow is wound in accordance with the direction of the thread. The first turn should act as a lock: for this, it is applied with a cross, at this time one side of the strand should be clamped by hand. Sealing the threads with flax should be as tight as possible, and there should be no gaps between the threads. The strand is then brought to the edge of the thread and glued with a suitable material.

Hello dear homemade products.

Until now, linen is the best thread reel. First, I will justify this statement, and then we will disassemble the process of execution.

The first alternative to flax is fum tape. There are at least three reasons why you need to give it up.

1. It is not known by whom it was made, despite what is indicated on the label, which means there are no guarantees of quality.

2. It takes a long time to wind it.

3. When tightening the thread, especially when installing valves, it is impossible to correct its position, that is, it can only be screwed forward. If you move a little back, then the connection on the fumka will flow.

The second alternative is a Tangit unilok lock pipe. I will not argue about the lock - he is dead, but as for the key: consider that you screwed it up, and the key was thrown away, so you can't find it.

Unscrewing will not work, only cut.

Flax is quite another matter. There are four reasons why it should be used:

1. One hundred percent guarantee against leakage.

2. Fast and accurate execution.

How to wind tow (flax) on a threaded connection (video)

The ability to adjust any connection back and forth, without the risk of leakage.

4. Easy disassembly, regardless of the service life.

Now, how all this is done.

Everyone knows that linen is not wound dry. Previously, it was impregnated with paint, but now, thanks to technical progress, silicone has appeared.

If the connection looked very untidy with paint, and had to be disassembled with a blowtorch, then with silicone it was a completely different matter.

The main thing is to use solid silicones. These include: KimTek 101E, Olimp, Macroflex, since, in addition to cushioning, they also have adhesive properties. With other brands, the connection turns out to be too mobile, although it still does not flow.

So, we take a threaded part, a flax pigtail, a syringe with silicone, and separate a small part from the pigtail for winding.

How much to pinch off the pigtail? In each case it is different. First you need to try to wrap the folder in a mother. It happens very easily, it can be tight (everything is like in life), and depending on this, the amount of winding is chosen.

Actually, after the first try it will become clear. If it squeezes out too much, then we take less.

First, we apply silicone to the thread, then, leaving a small tail, and pressing it with your thumb to the part, in the direction of the thread, we wind the flax with an interference, trying to cover the entire surface with it, that is, so that it does not go with a tourniquet.

If in the process of winding you realize that there is already a surplus of flax, just cut off the remnants. The remaining tail is also started in the direction of the thread.

After that, with your finger, we smooth out the entire winding so that the hairs do not stick out on the sides, and most importantly, do not block the passage hole.

Now we wrap it up, while it is imperative that part of the winding is squeezed out. It can be easily removed with a rag, and the more you press the rag against the part, the more accurate the connection will be.

This is how flax winding is done.

I wish you success in your work.

How to wind flax onto a thread

In order to achieve the strength and tightness of the connection, builders and plumbers use in their work flax or special linen tow, which is wound on the thread of the butt elements.

In order to achieve the truly desired results, it is important to know how to wind flax onto threads correctly.

Instructions on how to wind flax on a thread

In order to properly wind flax on the thread, you will need:
- tow (flax);
- silicone;
- plumbing wrench.

Prepare the connecting elements, having previously cleaned them from rust, if suddenly there is one. For this, you can use fine sandpaper.

How to properly wind flax on a thread.

When removing rust, be careful not to damage the threads.

Take a tow and separate a small strip of fibers from the main bundle, which you straighten along its entire length.

There should be enough fiber to make the connection tight, but not tight, otherwise, when the temperature rises, for example, in a heating pipe, the connection may simply burst. In addition, excess flax will be squeezed out of the threaded joint during assembly, and this will almost certainly cause a new leak.

Please note that pipelines with a die-cut thread, as a rule, have a fairly rough surface, but fittings with a smooth surface must be prepared. To do this, use a plumbing wrench or a triangular file to make small notches over the threads.

Take a flax, and attach the end of the fiber to the very edge of the thread. Start winding the tow in the opposite direction from tightening the nut. It should be wound in such a way that each subsequent turn tightly presses the previous one. If there is not enough linseed fiber to cover the entire thread, take another bunch.

On top of the fiber that is wound on the thread, apply a thin layer of silicone or special paste: this will achieve a tight connection.

Twist the threads while the silicone has not yet cured. Remember, there are 8-10 minutes before the end of this chemical reaction. There is no point in fixing the small amount of tow that remains outside the connection - the sealant will hold flax well. However, plumbers working with metal pipes sometimes simply set the end of the bundle on fire. Doing this at home is not recommended.

Plumbing threaded connections - doing it right

Whatever plumbing work is carried out, whatever piping systems are used, threaded connections cannot be avoided. Naturally, the seal of the joint must be of high quality, otherwise problems cannot be avoided. In this article we will look at the best way to seal the connection, how to do it, and some more points. If you think that this operation is simple and does not deserve attention - take your time, take a few minutes to familiarize yourself.

How to seal

There are many types of seals available for sealing threaded connections. Ribbon "fum", flax, "tangit" - sometimes the eyes run up from the choice. Recently, a novelty has appeared - an anaerobic sealant for threaded joints (please do not confuse it with flax paste), which greatly simplifies the procedure.

Anaerobic sealant has a couple of significant drawbacks: 1. The parts to be joined must be dry and clean - this can be a serious problem when repairing and replacing parts in a working system. 2. It takes time for the sealant to harden, albeit insignificant, but it slows down the entire installation process. In addition, there is reason to believe that the connected parts should not be disturbed in any way during subsequent repairs. In general, such a solution is suitable for a beginner, for minor repairs. This material is not quite suitable for a professional.

Note: A good plumber will connect to any of the above seals and will not leak. We will focus on the time-tested material that is used by the overwhelming majority of specialists: sanitary flax and paste for it.

In general, flax can be used without investment paste, but it generally increases the reliability of the joint and simplifies the operation. Linseed fibers tend to rot over time or dry out on hot water pipes - the paste prevents these problems. An important property of the paste is the ability to hold pressure in a loosely twisted thread.

How to reel

I'll make a reservation right away: maybe someone performs this operation differently. But for my own I can say with confidence: the connection is tight and reliable.

A small bunch of flax is taken, approximately as in the photo below, this is for winding a half-inch pipe ("1/2"). In general, the ability to take flax exactly as much as needed for a specific connection comes with experience. One thing I can say for sure: it is better to overdo it than take less than you need.

Linen is wound on the thread from the edge to the base, in the direction of the thread. If you look at the end, it turns out clockwise. It is not essential to get into every groove and go strictly in a spiral. The direction of winding, tension is important and that the thread is covered with an even layer of flax over the entire surface. It is even possible to lay the winding in several layers if the bundle is initially taken too thin.

With what force to tighten

It is impossible to give any numbers here, because the tightening is done manually. On the one hand, the stronger the better, but you should remember about the fragility of the parts to be joined. Modern plumbing accessories are rather weak in comparison with Soviet ones.

Often, when tightly tightened, the internally threaded part bursts. Even if everything worked out and the parts are intact, strong stress can affect later in the form of a crack on the tee and a leak.

After twisting, the crawled paste is removed with your finger. The result is a neat connection, without flax fibers sticking out in all directions. That's all science!

In conclusion, I would like to say: you should not be careless about the described operation. From experience I can tell - eight out of ten connections of careless "specialists" begin to flow after a short time.

So, in order, the information is confirmed by the test reports of the leading manufacturers of polystyrene concrete, I made a conclusion for myself and wrote at the end of the commentary. WATER RESISTANCE and HYGROSCOPICITY This is the most important property of any building material, especially in areas with high humidity. The higher the moisture resistance of the material, the more durable, stable and warmer it is. Polystyrene concrete absorbs no more than 6% moisture from the atmosphere; it can be outdoors for almost unlimited time. STRENGTH Due to the super-strong cement-polystyrene matrix, polystyrene concrete has unique strength characteristics. This material is so strong that a fall from the height of a five-story building will not cause significant damage to the block. FIRE RESISTANCE Polystyrene concrete does not burn, it is able to withstand huge temperatures caused by fire, due to its unique coefficient of thermal conductivity, does not allow heat to penetrate deep into the wall. Flammability class NG. Fire resistance class EI180. DURABILITY The service life of a polystyrene concrete house is at least 100 years. Over the years, the strength of polystyrene concrete only increases. FROST RESISTANCE Tests for frost resistance and amplitude of temperature fluctuations from + 75 ° C to - 30 ° C were carried out on 150 freeze-thaw cycles without loss of integrity and thermal insulation capacity. THERMAL INSULATION It has long been recognized that polystyrene (foam) is the best heat insulator in the world, it is even warmer than wood! A house made of polystyrene concrete does not require insulation: it is cool in summer and warm in winter. NOISE INSULATION Polystyrene concrete provides the best rate of noise absorption, 18-20 cm attenuates sound from 70 decibels. Consequently, in a house made of polystyrene concrete, there is special comfort: noises from the street and from inside from neighboring rooms and bathrooms are not disturbed. ECONOMY The cost per square meter of the finished wall is cheaper than other materials. Due to the high level of heat preservation, walls made of polystyrene concrete can be erected 25% thinner than from alternative materials (aerated concrete and foam concrete) and 4 times thinner than from brick. Saving on wall thickness leads to an overall saving on the construction of the box (foundation, roof and walls) up to 50%. At the same time, the quality of the house will be even higher, and the house itself will be warmer. SEISMIC RESISTANCE Seismic resistance 9-12 points. Polystyrene concrete has not only compressive strength, but also the highest tensile and bending strength. Therefore, polystyrene concrete is considered the most reliable and earthquake-resistant material. LIGHTNESS A large-sized block 200x300x600 mm does not exceed the weight of 17 kg, which facilitates the work of a bricklayer and reduces the time for laying walls: it replaces 20 bricks in volume, and is almost three times lighter in weight. ANTISEPTICITY The additive used in the manufacture of polystyrene concrete does not allow insects, rodents to enter the walls, prevents the formation of mold and mildew, which have a negative effect on health. STEAM PERMISSION Walls made of polystyrene concrete "breathe" similarly to walls made of wood, and there is no danger from condensation and waterlogging for them. This provides a comfortable environment in polystyrene concrete houses. PLASTICITY Plasticity is the only material made of cellular concrete that makes it possible to manufacture window and door lintels, its flexural strength is 50-60% of the compressive strength, for concrete this parameter is 9-11%. CRACK RESISTANCE Polystyrene concrete, due to its elasticity, is incredibly resistant to cracking. And this guarantees a long period of preservation of the interior decoration and the durability of the whole house. TECHNOLOGY High speed of erection of wall structures due to the lightness and convenient geometry of the blocks. Easy to saw and groove, the ability to give the building material any geometric shape. ENVIRONMENTAL The International Building Code (IRC) classifies polystyrene as one of the most energy efficient and environmentally friendly insulation materials. Thus, polystyrene concrete has a lot of undeniable advantages over such materials as expanded clay concrete, autoclaved and non-autoclaved aerated concrete, foam concrete, wood concrete, etc. The disadvantages of polystyrene concrete appear only with the wrong choice of its brand and violation of the masonry technology and preparation for interior decoration. We can say with absolute certainty that there is not a single significant advantage for materials such as aerated concrete and foam concrete over polystyrene concrete. At the same time, polystyrene concrete significantly surpasses them in key characteristics.
