Inter-crown insulation: purpose, types and features of use. Tow, jute or linen? Which interventional insulation should I choose? Inter-crown insulation jute or linen

In the house from natural wood A special atmosphere reigns, because an optimal level of moisture is naturally formed there, and the air itself is clean and fresh. However, to build such a house, it is not enough just to stack logs - Special attention it is necessary to pay attention to the quality of inter-crown insulation, which serves as a necessary layer for hydro- and vapor barrier.

The most popular interventional insulation materials today are made from flax and jute. There is no clear answer to the question of which one is preferable; only by carefully studying the characteristics of each of them and applying them to the individual situation can you make the optimal choice.

Intercrown linen insulation

A layer of flax, correctly laid between the logs, ensures high-quality “breathing” of the walls and the proper level of humidity inside the room. Linen is a natural fiber that does not cause allergies, is not static and is not attractive to fungus and bacteria. Linen insulation is excellent for building baths, because it provides good ventilation. And every consumer knows about the environmental properties of flax - it is difficult to find a more natural and healthier material.

Inter-crown insulation made of jute

Jute insulation appeared on the market relatively recently and has already gained popularity. This modern material is made from imported raw materials - jute, produced in India, Pakistan, and Bangladesh. Flax is sometimes used as part of jute insulation, but insulation made from 100% jute has the best performance properties, which can be purchased at affordable price possible on our website.

The jute tape is easily spread over the crowns, and the walls acquire an aesthetic and neat appearance and do not require additional processing. Even the color of jute is golden, closest to the natural color of the tree. This type of insulation is not pulled apart by birds, is not attractive to rodents, does not generate dust, and has excellent hygroscopicity. In operation, jute insulation is in no way inferior to flax, and even surpasses it in many performance qualities.

When thinking about which of these materials is best suited for your building, you should carefully weigh the pros and cons in order to make a choice in favor of traditional flax or a more modern and advanced material - jute.

Having found a compromise between monetary costs and the performance properties of inter-crown insulation made of flax or jute, you can choose the material that suits you, which can always be purchased from our company.

The use of flax jute in the construction of log houses

The scope of application of natural insulation made from flax and jute is quite wide. Due to its good resistance to moisture, insulation made from flax and jute is used for insulation and laying of crown joints in the construction of log houses, bathhouses, houses made of timber and rounded logs.

Photo: flax jute can be widely used both in the construction of log houses from timber, and in the construction of ordinary and rounded logs. Flax jute is the optimal and the best choice in terms of price-quality ratio of natural insulation material.

Very good characteristics shows flax insulation when caulking seams between logs, filling installation gaps, when installing windows, doors, for thermal insulation of roofs, floors and ceiling surfaces, sound insulation and insulation of interfloor ceilings.

The main feature of using linen insulation, according to the reviews and assessments of many construction specialists, is the natural ability of linen insulation to remove excess moisture from the room, thanks to the capillary structure of flax fibers.

If we do not take into account jute, then flax insulation would occupy the lion's position as inter-crown insulation in the construction of log houses. Therefore, answering which is better is flax or jute. Jute insulation is the best in terms of resistance to excess moisture, which is not uncommon during assembly wooden houses and log houses with natural humidity.

If you follow the technology of laying insulation from flax or jute, when installing wooden houses from timber or logs, the seam of the insulation turns out to be absolutely perfect, performing the functions of not only insulation, but also a good barrier against moisture, the formation of mold and mildew, between the seams and in places use of linen insulation.

Jute grows in a tropical climate, is processed and cut only by hand, so its cost is slightly different from the cost of flax insulation, but having a tubular structure it removes moisture formed between the timber or logs more intensively and quickly. It is produced mainly in the form of rope rolls wound on bobbins of various diameters and lengths. A feature of the popularity of jute insulation, despite its higher cost, is not only resistance to moisture and rot, but also appearance, ease of use. Twisted in the form of a rope or tape, jute, 15-20 mm thick, is very easily laid between logs. The thickness of the jute tape or rope allows it to be used for laying in one layer, which saves a lot of time and money.

Photo - jute is considered better due to its higher resistance to excess moisture, which is not uncommon during the assembly and construction of wooden houses and log cabins in middle lane Russia.

Unlike flax insulation, jute insulation manufacturers provide a guarantee that the right conditions its service life will be at least one hundred years, without additional protection with antiseptics and caulking.

Conclusion

According to statistics, the majority of construction organizations involved in the construction of wooden houses have switched to the use of jute and consider it better insulation material for laying between logs and between beams.

Since ancient times, log baths were insulated exclusively with caulking - when manually pushing natural material. And this method, of course, has its undoubted advantages. But the downsides are not encouraging either: not only is all the work on caulking quite labor-intensive, requires special skill and takes place in more than one stage, but many bathhouse attendants have gotten into the habit of pulling out the caulking itself by birds. Why do experienced builders immediately recommend covering such a bathhouse with expensive siding - but why would it even be built from environmentally friendly, beautiful logs? But, fortunately, today there are already other types of interventional insulation - no less environmentally friendly, even more practical and not at all expensive. This article will help you decide which modern inter-crown insulation is better.

Inter-crown insulation: how to choose? What is the best inter-crown insulation for a bathhouse? These questions cannot be answered unambiguously - each has its pros and cons, and some advantages.

Inter-crown insulation made of sheep wool

A good inter-crown insulation for profiled timber is made from sheep wool. It is simply ideal for insulating a wooden bathhouse - although it costs quite a bit. But it does not cake at all and is significantly superior in quality to all modern tape insulation materials.

Tape inter-crown insulation

This insulation is quite new for Russian market, however, has already managed to gain its popularity. Its main advantages are that, in general, the entire assembly of the structure occurs quickly, labor costs are reduced, and the insulation itself does not accumulate moisture, is not blown, is hypoallergenic and is not at all attractive to birds. High-quality tape insulation is glued together after laying the walls.

Its composition is interesting: natural fibers are pierced by special needles with barbed hooks, and, intertwining with each other, these fibers form a fairly dense substance, which in its structure resembles felt. His standard sizes are as follows: length – 10-50 linear meter, width – 100/125/150/200 mm, and thickness varies from 5 to 15 mm. This insulation also has a different surface density – 300-800 g/sq.m.

But the most important thing is to correctly determine the thickness of the tape insulation, because... it must be selected depending on the thickness of the log house. So, for chopped wood you need insulation 15 mm thick, for ordinary timber - 8-10 mm, and for glued timber - 5 mm.

There are also some peculiarities of laying such insulation. So, if the timber is uneven, it is better to lay the tape in two layers.

The tape insulation itself today is made from flax or jute, or in a combined version - flax and flax wool, the percentage of the ratio of materials in which can be different. This is what determines their quality and scope of application.

The popular jute inter-crown insulation is today considered an excellent alternative to expensive caulk. It is a tape with a thickness of 5/10/15 mm, quite dense and uniform. You need to roll it directly along the groove, fixing it along the way with a construction stapler. And after laying the log house, the jute will become even more compacted - its fibers will stick together and acquire enviable resistance to wind and moisture.

Walls with this insulation turn out beautiful, with perfect seams, warm and do not need any other finishing. And jute fiber, unlike flax, is of uniform thickness and easily spreads over the crowns.

Intercrown linen insulation

Although this material also has its advantages. For example, it quickly absorbs and quickly releases moisture, and the walls really “breathe.” Linen is not allergic and not hazardous to health, does not create a static charge and is good at preventing the appearance of fungus on the walls. In addition, if the inter-crown insulation for the timber is made of flax, the bathhouse does not need any other ventilation. And the most important thing is that such insulation does not have a sharp edge, and therefore the bundles can be made by hand of any length and shape.

And finally, more environmentally friendly pure material There’s no way to insulate walls – it’s not without reason that even linen clothes are considered healing.

Combined insulation: interventional insulation flax wool

As for the combined options, the more jute in the tape insulation, the less water permeable it is. After all, this plant material contains a special lignin polymer, which holds together those same cellulose fibers in wood. But flax contains only 2% of this substance, and therefore it is more susceptible to moisture. In addition, the more flax in the insulation, the more likely it is that moths will eat it, but the pest does not like jute. And jute is blown much less than flax.

How do you know that there are no flax additives in inter-crown insulation? Easy - by color. It should be golden, i.e. light brown, but gray inclusions indicate that flax was added to it.

In general, combined materials for insulation can combine very different qualities, and therefore they are called universal. Their only drawbacks are rigidity and fragility, which, however, is regulated by the addition of flax to them.

So, have you made your choice? And now the most important thing is to lay the material correctly: slowly, carefully and without sparing the material. Then your bath will look beautiful and delight you with freshness and pleasant aromas.

Quite common for those starting construction wooden house from timber, a wooden bathhouse or a log house. The modern building materials market offers a wide range of insulation materials. How to choose the best insulation option and how to distinguish between them? Which insulation is better? Next we will try to answer these and other questions. For clarity, we present the comparison of inter-crown insulation in the form of a table (score based on indicators) and a graph:

Moss does not rot and has good bactericidal properties. Cuckoo flax moss and sphagnum moss are most often used as inter-crown insulation. To insulate a house with moss, you need special installation skills - this is quite labor-intensive work. To insulate one crown, more than two workers are required. Moss is the most difficult to work with; before laying, you need to select cones, twigs and other debris. This inter-crown insulation is difficult to install in windy weather. Today, moss, as an inter-crown insulation material, is used mainly for the construction of log bathhouses in the areas where it grows. Its main disadvantages are fragility and large shrinkage.

Jute interventional insulation

Jute inter-crown insulation is becoming increasingly popular in wooden house construction. This material has many advantages, the main ones being low cost, high thermal insulation and ease of installation. Jute is not affected by moths and is not pulled apart by birds. Jute fiber is strong, hygroscopic and contains a lot of lignin polymer (more than 20%), which determines the affinity of jute with wood, and also makes jute resistant to moisture and decay. Jute does not rot on its own, and, very importantly, like moss, it prevents wood from rotting. At the same time, the seams turn out to be so smooth and beautiful that you don’t have to bother yourself with additional interior decoration.

Hemp and flax tow

Tow is a coarse, short, matted fiber, a waste product from the primary processing of hemp, flax and other bast crops (during softening and fraying), unsuitable for spinning and heavily contaminated with fire (woody parts of the stems). Hemp (hemp - hemp fiber) and flax tow It is difficult to distribute in an even layer, since it is usually clogged with fire, and therefore there is a need to re-caulk the already assembled log house. The fibers in tow are very short, which is why tow is not entirely suitable for caulking. The obvious advantages of flax fiber and tow include their environmental friendliness. But there are several more disadvantages: this is flammability, susceptibility to rotting, and the possibility of insects, and being carried away by birds.

Lnovatin

Flax batting is often mistakenly called flax-jute or jute felt. Why is it wrong? Yes, because there is no jute in it at all. After all, flax wool is produced from short-fiber flax “dust” or “shaking” remaining after cleaning the long fibers used in weaving. Linen wadding can be needle-punched or quilted. Linen is highly flammable, gets wet, and is therefore susceptible to rotting and fungal attack. Flax and moss are taken away by birds and insects, including moths, can live in it.

Inter-crown insulation made of sheep wool

Inter-crown insulation made of sheep wool does not rot and is not affected by fungi. In Russia, new insulation made from sheep wool appeared not so long ago. Time will tell how well it corresponds to its declared properties, in particular in terms of hypoallergenicity and resistance to moths and other insects. A significant disadvantage of inter-crown insulation made from sheep wool is its high price!

On the insulation market there are both synthetic insulation and synthetic blends. Such insulation materials are softer, looser and thicker. They are pleasant to the touch. However, during use, little air flows between the crowns, and the wood begins to suffocate. The synthetic lining prevents air ventilation and creates favorable conditions for wood rotting.

Thus, the best option Jute roof insulation is used as inter-crown insulation for wooden log and timber houses, bathhouses and log houses. Jute insulation is durable, comfortable, does not rot, protects wood from rotting, is durable, and very easy to use. The insulation comes in rolls of various widths, so you can always choose the one that matches the diameter of the logs or the width of the beams of your home.

Jute inter-crown insulation, produced by PKF Technotex, is distinguished by uniform thickness, uniform density, is made only from 100% BTD jute fiber, and is supplied in thermal packaging.

Wooden beams - excellent construction material. It is lightweight, absorbs and releases moisture, and its thermal conductivity is several times lower than that of brick, concrete or stone. The only serious drawback of this material is the change in size during the drying process. Therefore, the dimensions of both the timber itself and the house made from it are constantly changing. In winter and autumn, the timber increases, absorbing atmospheric moisture, in spring and summer it decreases, because during the drying process the moisture evaporates. Because of this, gaps appear between the crowns, which increase heat loss in the house, and this negatively affects the microclimate of the rooms and increases heating costs. In this article we will talk about the various insulation materials that are used in the construction of houses made of timber, and also give recommendations on choosing the most suitable one for specific conditions.

Requirements for interventional insulation

IN wooden houses, including those built from timber, it is necessary to use only organic insulation. This is due to their characteristics, the main ones of which are:

• the ability to absorb and release moisture without increasing thermal conductivity;
• resistance to high humidity;
• flexibility and elasticity;
• UV resistance;
• inapplicability for the construction of bird nests and burrows of various small animals.

One of the main requirements for insulation is the ability to retain its properties even after getting wet, because during rain, the insulation absorbs a certain amount of moisture. Therefore, they are not used as insulation mineral wool, which sharply loses its thermal insulation properties when wet or strongly compressed. An equally important characteristic is the ability to absorb and evaporate moisture. After all wooden wall absorbs moisture both from rain and from the room, so wooden houses with normal ventilation are never damp or too dry. If the insulation absorbs well, but does not release moisture well, then the timber will begin to rot, which is why the house will soon begin to collapse. Therefore, modern synthetic insulation cannot be used for. They absorb water well, but do not evaporate it well, which is why the timber at the point of contact with the insulation will constantly become damp. In such conditions, the appearance of rot and fungi is only a matter of time.

Important characteristics of insulation are flexibility and elasticity. When a house is being built, the pressure on the insulation of the lower crowns is maximum. Then summer comes, the timber is exposed to the heat and sun rays loses moisture and dries out, causing gaps to appear between the crowns. If the insulation is not elastic enough, it will remain crumpled and compressed, as a result of which the joint between the crowns will become a source of cold. Therefore, a house with unsuitable insulation often has to be caulked, because this is the only way to avoid drafts in winter. An important factor influencing the choice of material is its demand among birds and various rodents, which can use it to create or decorate nests and burrows. Therefore, for use as inter-crown insulation, it is necessary to use only those materials that will not be attacked by birds and rodents. Otherwise, they will pick out the insulation from the walls, which will lead to an increase in their thermal conductivity and the appearance of cold bridges in winter.

What kinds of inter-crown insulation are there - jute, flax

Most often, the following materials are used as inter-crown insulation:

• jute;
• flax wool;
• felt.

Which interventional insulation to choose + Video

When starting to choose insulation, first of all calculate the required amount of material. To insulate profiled or laminated timber, the insulation consumption is 200–400 grams per square meter of total insulated area. For sawn and planed timber, the consumption is 300–500 grams per square meter. For timber with natural humidity, insulation consumption is 350–600 grams per square meter. After this, it is necessary to determine the thickness of the insulation. For dry profiled and laminated timber, the optimal thickness is 3 mm. For sawn and planed timber, the optimal insulation thickness is 4–5 mm. For timber with natural humidity, the thickness of the insulation should be from 6 to 10 mm. This is due to humidity and the shape of the timber. Having determined the quantity and thickness of insulation, find out the cost in stores various materials, then calculate the price of the entire volume and think about whether you can afford such expenses. If installed correctly, any of the materials described above will provide excellent insulation for a house made of timber, so there is not much difference between them.
