Today, in the US and Canada, almost 70% frame houses cellulose-based insulation is used. In Russia, this material has been known since the middle of the last century, but to this day, the domestic consumer treats it with caution. Why?
Cellulose insulation (ecowool) was developed at the beginning of the last century, during the construction boom, when practical and inexpensive materials were in great demand.
The product, which is based on recycled paper, came in handy. It is because of the opened possibility of waste disposal, which used to simply litter the environment, that the prefix "eco" appeared in its name.
What is ecowool made of?
So, most this insulation (about 81%) is cellulose, or, more precisely, recycled waste. Up to 12% are antiseptics and fungicides (boric acid or ammonium sulfate / phosphate), which provide protection against pests. And finally, 7% are fire inhibitors. The material is exceptionally easy to manufacture ( full cycle only takes five minutes) and is affordable. Ecowool has other advantages that make it popular in the US and Europe.
First of all, these are high thermal insulation properties. With a thermal conductivity coefficient of 0.037-0.042 W / (m-K), a layer of sprayed ecowool of 150 mm corresponds to energy saving brick wall 4.5 bricks thick. The material application technology (filling or spraying) provides a uniform heat-insulating layer without voids, seams and gaps.
Despite its "paper" nature, cellulose insulation does not ignite upon contact with fire, but only smolders and, having lost a heat source, fades itself. Due to the capillary structure of cellulose fibers, it is able to retain up to 20% moisture in the upper layers, without losing heat-insulating properties.
Vapor barrier is not required for it. Antiseptic additives make ecowool immune to attacks by harmful microorganisms, insects and small rodents. It is also worth noting that cellulose insulation has high soundproofing characteristics, significantly exceeding in this indicator mineral wool. A layer of material 100 mm thick reduces the noise level by approximately 60 dB. If you use it not only in the outer walls, but also in partitions, the house will become much quieter.
The composition of ecowool
As mentioned above, ecowool is made from paper raw materials with the addition of antiseptics and fire inhibitors. Let's consider these components in more detail and start with the main thing - waste paper. Overseas manufacturers tend to use ink-free paper, which is known to contain unsafe lead. Domestic companies, unfortunately, sometimes do not disdain newspapers and other waste materials that are not suitable for the manufacture of thermal insulation. Therefore, when buying ecowool, it is important to at least visually check it for scraps of cardboard, coated paper (which forms the smallest dust), rags and other debris.
Boric acid- antiseptic, time-tested, does not raise questions. Its concentration is too low to create any health problems for residents. But with flame retardants, everything is more complicated. The fact is that ammonium sulfates and phosphates, used by some manufacturers, can be a source of an unpleasant ammonia smell.
In addition, over time, these substances lose their fire-fighting properties, as evidenced by studies conducted at the California Bureau of home furniture and heaters.
Borax (borax) does not have the above disadvantages. So when choosing a material, it would be wise to give preference to the one in which the drill was used. By the way, the borax is an additional guarantee that rodents will not start up in the wall structure - they cannot tolerate this substance.
Areas of application of ecowool:
1. Attics. 2. Walls. 3. Floors and floors. 4. Attics
Installation of ecowool
Cellulose insulation is used for thermal insulation of walls, interior partitions, attic and attic space, as well as roof structures and floors on the logs. But it cannot be laid under the screed: it is a loose material that needs free space. Ecowool is delivered to the object compacted (3-5 times of the nominal density), so it must first be brought to its original state. During manual laying, the material is loosened with improvised tools in any large container and laid out on insulated surfaces (floors, ceilings) or fall asleep in the cavity frame walls and overlays. It is very important to observe the application density: for horizontal structures it is 35-40 kg / m 3, for vertical - 60-70 kg / m 3. This method It requires a lot of time and effort, and therefore it is used extremely rarely, only with small amounts of insulation.
Much more productive is the application by means of a blowing machine, which loosens the insulation in the bunker and delivers it in the air stream to a distance of up to 200 m horizontally and up to 40 m vertically. In this case, the material penetrates into the most inaccessible cavities and gaps, forming a continuous and seamless heat and sound insulating layer. The technique allows you to adjust the density of the blown insulation, which means that it becomes much easier to observe the quality of installation. It is important that ecowool is blown out with a margin of 10%, since even with the most competent application, it will settle a little over time.
Well, wet laying is considered the most reliable, when ecowool is applied to structures with water or diluted glue, which significantly increases its adhesion to the base. Wet-glue method, used primarily for sloped surfaces ( pitched roof, vaults, arches), allows you to achieve a perfectly uniform and even layer of insulation.
Disadvantages and disadvantages of ecowool
And now it's time to answer the question: what is holding back the spread of this insulation in Russia?
First of all, the fact is that in the Russian Federation there is no normative documents, regulating the composition of ecowool, which means that the quality of products remains on the conscience of manufacturers. It is also worth noting that, although ecowool does not support combustion, it can smolder, because it is a wood product. Therefore, when insulating attic, attic rooms additional insulation of the chimney with non-combustible materials is required.
Moisture in ecowool applied with a wet adhesive method can adversely affect the surface to be insulated. All metal elements(fasteners, wires, pipes) must be painted or varnished to avoid corrosion, because the material will dry for quite a long time - up to two months. And of course, at this time, finishing work will have to be postponed.
And finally, the most tangible drawback is the price. The material itself is cheap, but its high-quality application requires qualified personnel, whose services will have to be paid. And the depreciation of equipment will be included in the price. On average, the cost of a cubic meter of insulation with turnkey laying, depending on the density and application technology, ranges from 1,700 to 5,200 rubles.

This additive serves as a flame retardant and antiseptic that does not support combustion and decay, does not allow the development of fungus and prevents the appearance of insects in it. Based on this, the production of cellulose wadding is economical, and therefore it was called econom wadding.
Method of production and composition
The production process of cellulose wadding has its own characteristics, it does not lead to slagging environment, does not require additional use natural resources and high energy costs, tk. does not have melting processes.
For it, paper waste is used, unsuitable for further use in the form of paper, due to large impurities of plastic. Over the years, production technology has only improved. Borax is an antiseptic, boric acid is a flame retardant.
Technical advantages
It is a wood fiber material having a thermal conductivity of 0.041 W/m K and low air permeability. This property of econom wool is due to its fine-grained structure. The small particles that make it up make it difficult for air to move.
Under the influence of the movement of moist air on top layer the heat insulator forms a thin dense layer in the form of paper - it prevents the further movement of air. Being a wood-based insulation, it has increased moisture resistance and does not require an additional layer of waterproofing.
The presence of a large amount of air in the pores (85-92%) makes the material a good heat insulator. Thanks to the addition of borax, cellulose wadding does not support combustion and does not melt. In case of fire, it smolders without releasing toxic gases. Additives of boric acid do not allow insects and moldy fungi to breed. This material has a high environmental friendliness.
Application methods
There are two ways to apply cellulose wadding - dry and wet. In both cases, this is a mechanical application of insulation, which significantly speeds up the process itself.
The density of such an insulating coating depends on the quality of its application. It is applied by blowing or sprayed using special equipment. This method allows the insulating layer to penetrate into any, even the smallest openings. Such material is very convenient for electrical work.
Cellulose wool is transported and stored in special bags. When carrying out work, it does not have waste, such as when cutting other types of heaters.
It is necessary to insulate a residential building for many reasons, and one of the modern thermal insulation materials, easy to use, efficient and durable - cellulose insulation based on ecowool. Ecowool consists of 81% recycled cellulose (in other words, waste paper), 12% boric acid, and 7% boron. Lignin is added in small proportions to improve surface adhesion. Environmental friendliness is ensured by the use of these non-toxic and non-flammable substances. A mass of insulation is blown (inflated) onto (under) the surface of walls, ceilings, floors with the help of compressor units, which is why the material is called blown insulation.
Characteristics and features of ecowool
Ecowool is a non-combustible material, but with high temperatures ah can smolder without creating an open flame. The material does not rot and does not get sick with mold, perfectly delays external noise, does not let heat through.
- Thermal conductivity coefficient - 0.037-0.042 W / (m K);
- After wetting and drying, the properties of the insulation are completely restored;
- Material density - 30-65 kg / m 3;
- According to GOST 30244, GOST 30402, DIN 4102, GOST 12.1.044, DSTU B V.2.7-38-95, the flammability group is G2 V2, D2, RP-1, which means: moderately flammable, moderately flammable, moderately smoke-producing, with zero flame spread over the surface;
- Air permeability 80-120 10-6 m 3 /ms Pa;
- Vapor permeability of ecowool - 0.3 mg / (mh Pa);
- Adsorption in 72 hours - 16%;
- pH - 7.8-8.3.
Advantages and disadvantages of blown ecowool
Blown cellulose insulation in composition can be basalt, fiberglass and cellulose. Basalt mineral wool is made from basalt rock, and formaldehyde is not added to it. Glass wool is the result of grinding thermal insulation boards, cellulose insulation is made from waste paper. Flame retardants and antiseptics are added to all types of thermal insulation.
Advantages:
- Small thermal conductivity and light weight;
- High moisture resistance and vapor permeability;
- Fire safety and incombustibility;
- Long service life;
- Easy installation.
Flaws:
- Compressor equipment is required for operation;
- On drywall surfaces, ecowool should be applied in two layers to avoid swelling of the surface;
- The need for surface waterproofing;
- The high cost of use with small volumes of insulation.
Ecowool layer calculation
Starting data you will need:
- Building material of the walls of the building;
- Average annual thermal resistance in the region (reference information);
- How many exterior doors and windows are in the house;
- Additional heat leakage;
- Thermal insulation material and heat transfer coefficient.
The formula for calculating the degree-day value of the heating period in the region:
GSOP \u003d (T 1 - T 2) x Z, where:
- T 1 - optimum temperature in housing (18-22 0 C);
- T 2 - the average annual temperature in the street;
- Z is the number of days in the heating season.
After calculating this regional parameter, you can begin to refine the thickness of the thermal insulation layer on the surfaces of a residential building. will also depend on the building material of the walls, ceiling or floor - for brick, concrete, cinder block or wooden surfaces results will vary.
How to work with blowing cotton
Cellulose wadding is applied in two ways - wet-adhesive (wet) or dry:
- "Wet" method - spray ecowool along with adhesive solution, which consists of glue and a special dispersed additive. The applied layer is cut to the required size and dried. This is a visual way by which you can control the filling of the void with thermal insulation. The wet method is bad because the glue should not freeze, so the work is carried out when outdoor temperature not lower than +5 0 С, and such a layer will dry for at least three days. In addition, when implementing this technology, ventilation must be installed in the room so that excess moisture can be disposed of. But the result will be of high quality: such thermal insulation does not allow moisture or heat to pass through.
- “Dry” method: blown insulation is sprayed on a surface pre-coated with kraft cardboard in a dry form, as it comes in packages. With the help of an additional coating, a limited space is created in which dry cellulose wadding will be located. Kraft cardboard is fastened with a stapler or adhesive tape, cotton wool is blown out with a compressor, and a vacuum cleaner can be used at home. Just before blowing, the material is loosened with a construction mixer, as shown in the figure:
The physical implementation of blowing out the insulation is divided into two possibilities:
- Manual blowing: preliminary loosening of the insulation, followed by blowing the insulation onto the surface or into closed space. Such a layer of thermal insulation will have low rates of heat and noise retention, therefore, ecowool should be stuffed as tightly as possible, and in order to achieve higher rates, this should be done in a small area. Such conditions can only be found in individual construction and repair of premises - this method is not suitable for large areas;
- Blow molding equipment: the method is applicable to any area and volume, the material is previously loosened mechanically. A compressor unit with a high air flow rate delivers insulation to the surface or into an enclosed space, thus high pressure in pipes ensures uniform distribution of ecowool over the entire insulated surface. Advantage: no joints and seams, no need to prepare the frame and dismantle it after work compared to the "wet" method of blowing.
Blow compressor equipment has the following device:
- Mobile platform with gearbox (to increase the feed rate of loose mineral wool), large diameter corrugated air duct and motor. The equipment is usually mounted on a car or tractor;
- As an engine, low-current devices with a low noise figure and minimal dust formation are used;
- The insulation is captured through a special gateway, ejected through the inlet hose. The supply of cotton wool is dosed by an automated damper;
- A mechanism for loosening ecowool, a loading chamber with a funnel, a control panel and an emergency stop switch.
It is not difficult to make a mechanism for blowing loosened cotton wool with your own hands. For this you will need:
- garden vacuum cleaner;
- Plastic tank for pre-loosened insulation;
- Corrugated hose of the required length, but not less than 8-10 m, Ø 60-70 cm;
- Electric drill with a construction mixer (you can use a screwdriver or puncher), adhesive tape;
- Ecowool.
AT plastic container with a volume of at least 50-100 liters, cotton wool is loosened with a mixer, then a hose connected to a vacuum cleaner is lowered into the container (ordinary adhesive tape is used to seal the connection), the second end of the hose is thrust into the blown space to the bottom (if it is a closed space), or cotton wool is blown within designated frame. For loosening insulation, an ordinary two-hundred-liter metal barrel. As the space fills (this will be heard by the sound of the vacuum cleaner), the hose is gradually raised. After blowing out the thermal insulation, all space and cracks are filled with material without cracks and joints, forming a monolithic heat-protective barrier. 
The main advantage that the owner of a private house or cottage receives is the low cost of the process and the high speed of installation with high-quality and durable insulation. For example, close flat roof one-story house in this way it is possible in just 2-3 hours to feast in the presence of all equipment and prepared materials. Hours of operation, equipment used and installation methods may vary depending on the particular roofing and operating conditions. Other roll and plate heaters, for example, polystyrene or mineral wool, for warming large areas in the private sector are ineffective in comparison with the blown method of applying ecowool.
What is ecowool? This is the collective name for thermal insulation materials that are manufactured according to special technology often made from recycled materials. The material cannot be called new: it has been used since about the middle of the last century and competes with modern views thermal insulation.
Manufacturers position ecowool as an environmentally friendly safe material With high performance, which is in the available segment construction market. How relevant these statements are, we will understand together.
The composition and properties of the insulation
In the manufacture of ecowool, the following components are usually used:
This composition is due to the low price of thermal insulation and its environmental safety. In fact, there is no toxic component here, however, relatively good specifications.
Now let's talk about properties. Performance characteristics ecowools look like this:
Flammability class - G2. Under the influence of high temperatures, a crystallized liquid is released from the fibers of the material; accordingly, the insulation ignites poorly and does not support combustion processes.
Biostability - high. The composition contains boric acid and borax, which neutralize almost any external factors and aggressive environment, make the material unsuitable for eating by rodents and other pests.
Thermal conductivity values: 0.032–0.041. The material protects interior spaces from drafts and cold wind, reduces heat loss, helps to save on heating in winter time of the year.
Density - up to 75 kg / m3. This provides reliable sound insulation of the building, forms a reliable moisture insulating layer.
In addition, ecowool is not produced in sheets or rolls, therefore, during installation, a monolithic thermal insulation is formed, which completely excludes cold bridges, seams and joints.
Advantages and disadvantages of insulating material
Despite the assurances of manufacturers that ecowool is the standard among thermal insulation materials, these statements should not be fully trusted. This is a common marketing ploy designed to increase sales.
The material has a lot of undeniable advantages, but, like analogues, it is not without serious drawbacks. Let's start with the merits.
The advantages of ecowool are the following characteristics:
Low moisture permeability. The capillary structure of the material allows water to be absorbed without loss useful qualities. For example, if a mineral insulation is moistened in total by 1%, heat loss will increase by almost 10 times. If ecowool is moistened by 25%, decrease in thermal conductivity will not exceed 5%. This is a very good indicator.
Seamless isolation. The loose mass of the filler fills all the voids, completely excluding cold bridges. To achieve a similar result with roll or sheet insulation, the material must be laid in 2-3 layers which increases the overall cost of the work.
High level noise reduction. Ecowool is a great way to insulate buildings that are located on busy streets, near federal highways, railway lines and airports.
Besides, indisputable advantage is an affordable price, which elevates ecowool to the rank of the most popular heaters for private construction.
Let's move on to problems. Serious disadvantages of thermal insulation include the following points:
gradual decline thermal insulation properties , increased heat loss. This is due to the fact that the material is reduced in volume or supersaturated with moisture. You can avoid problems by laying insulation with a margin in 20-30% from the calculated volume and making the layer ventilated so that moisture can evaporate into the atmosphere.
Difficulties in installation. In order for the insulation to fully meet the technical specifications, special installation equipment will be required. This means that you will have to hire a team of professionals, and these are additional costs.
Loss of time. Ecowool can be laid in two ways: dry and wet installation. The first option creates a lot of dust during the work and does not guarantee high-quality compaction. The second - creates a high-quality layer of thermal insulation, but the material will dry about 3 days, which is not always possible with the pace of modern construction.
Relatively low stiffness. If we compare ecowool with other types of insulation, for example, foam boards, its rigidity will be noticeably lower, which makes it impossible to use the material for frameless insulation.
Material shrinkage. Occurs with vertical insulation already in the second year. This problem cannot be avoided.
Burning speed up to 30 seconds. This means that the material does not burn, but slowly smolders. As a result, there is a risk of ignition of adjacent materials and high smoke.
As you can see, ecowool is not a perfect thermal insulation. This is a rather specific material with a limited scope and a peculiar installation technology. In addition, doubts are also raised by assurances of environmental safety: boric acid and borax can hardly be called fillers that are safe for humans.

What is the difference between ecowool and basalt insulation
To answer this question, a little clarification is required. In the production of basalt insulation, the following components are used:
Considering that the main component is basalt, it is customary to unite the entire heater of the stone-basalt group under the term "basalt wool".
In fact, basalt insulation is insulation that is completely made from this rock. Such material is not used in residential construction. Its intended use: insulation of equipment and pipelines.
If we compare ecowool and heaters of the stone-basalt group, we can see a lot in common. In particular, both materials have similar thermal insulation performance. However, basalt wool has a higher density, which requires a reliable frame.
Ecowool has a light structure, so it does not increase the load on bearing structures. Besides, basalt insulation is produced in the form of plates, which leads to the formation of voids at the joints.
Service life of basalt wool does not exceed 40 years- the material is gradually destroyed under the influence of pathogenic microflora. Ecowool serves up to 70 years without losing the original properties.
Real consumer reviews that we found on the Internet
To better understand the feasibility of ecowool insulation, you can refer to the reviews of people who have already used this material in construction.
Sergey. forumhouse.ru
I bought ecowool for insulation country house. The workers who were involved in the construction advised this particular material. For insulation, additional layers of vapor and waterproofing are not needed, which was the decisive argument. The house stands 3 years already, I have no complaints about the insulation, only positive emotions.
Kirill. vk.com
I do not recommend ecowool. 5 years lived in a house insulated with this insulation and was constantly treated for allergies. When I changed my place of residence, the problems disappeared. The doctor said that the body's reaction was provoked by cellulose (an allergy to paper and library dust).
Note that there may be a case of individual intolerance to the components, therefore, before choosing thermal insulation, it makes sense to consult a doctor in order to avoid unpleasant consequences.
Yuri. otzovik.com
Very happy with ecowool. The material fully complies with the declared characteristics, provides reliable insulation, is easy to use and attracts attention. affordable price. Found only one drawback: compliance with storage conditions. When exposed humid environment, the material is covered with a hard crust, which complicates further use.
Also, many users express concern about the content of borax and boric acid in the composition of the insulation. In addition, the use of special equipment causes dissatisfaction, but this is a prerequisite quality installation, which cannot be excluded.
TOP-3 verified manufacturers
ISOFLOC. A German brand offering quality ecowool for multi-purpose use. Isolation deserved positive reviews professional builders worldwide.
TERMEX. Finnish company supplying insulating materials on the Russian market since 1988. The manufacturer carefully controls the quality of products, adheres to a reasonable pricing policy.
"Equator". Russian company manufacturer of insulation since 2007. Production Line fully automated, high-tech equipment is used. Currently, it is one of the largest domestic manufacturers ecowool.
In addition, the company's insulation is trusted by consumers. "Nanovata" and EKOVILLA.
current issue in modern construction- how to insulate the room. There are many ways, as well as types. But the most preferred option for insulation is ecowool.
Ecowool is a cellulose insulation (where does its name come from). Ecowool production based on waste paper recycling. Therefore, being made from fluffy waste paper, it has a loose texture.
Thanks to this, it is possible to blowing ecowool air in the cavity, after which it is moistened and sprayed onto the surface. This method of use makes this material suitable for both insulation and insulation.
Some of its properties allowed her to achieve high popularity:
Little breathability. Air movement at ecowool insulation reduced due to its structure - the small size of the wood fibers that make up the composition;
Moisture resistance. Due to its structure, ecowool does not accumulate liquid and does not require a vapor barrier layer, since condensation does not occur;
Soundproofing. The quality of sound insulation when using ecowool is very high, because due to the absence of voids in the material, it can be laid in a continuous layer;
Hypoallergenic. The likelihood of an allergy to this material tends to a minimum;
Fire safety. Ecowool is a material that itself resists fire due to its characteristics and composition.
Nice bonus, among other things, is that mice do not live in ecowool. Thanks to the antiseptic included in the composition, living in ecowool becomes extremely unattractive for rodents.
Ecowool includes:
cellulose fiber - 81%
flame retardants (the very substances that protect the material from burning) - 12%
non-volatile antiseptic materials (boric acid) - 7%
Application of ecowool
Due to its properties, ecowool quickly became popular in construction. Performance characteristics allow it to be used for private and industrial buildings.
Its main purpose is insulation and soundproofing in rooms. You can make installation on any floor of the building, insulate the basement and roofing, as well as lightweight frame structures.
If necessary, it can be used to reconstruct old buildings. This material, among other things, is useful in the creation of heat-insulating surfaces.
The flame retardants included in its composition contribute to fire resistance, so it is used in the manufacture of products that must have a high temperature.
Soundproofing is carried out both between floors and in adjoining rooms. It can be used as soundproofing plaster. When creating a room that should not have an echo (music studios or clubs), ecowool will also be useful. It is also used as an additive in bitumen-asphalt mixtures.
A wide range of applications of cellulose insulation is increasingly forcing builders to think about buying ecowool and, accordingly, its price. Ecowool price varies from city to city. Thus, the pricing policy depends on many factors and covers the range price per bag of ecowool from 400 to 1500 rubles.
Advantages and disadvantages of ecowool
The advantages of ecowool include the properties already described above:
low air permeability - thermal insulation;
fire resistance;
laying without seams;
hypoallergenicity;
mold and rodent protection.
But ecowool, like any other type of insulation, has its drawbacks.
The first thing builders who choose this material for insulation note is its price. It is several times higher than other types of heaters, but if desired, it can be made independently, not without loss of quality, of course. It would be nice if this were the end of her shortcomings, but this is not so.
Installing ecowool is a rather complicated process. If its installation is not carried out by professionals, the result may be disappointing. One of the dangers self-assembly is the probability of laying out an uneven layer, then its main advantages in the form of heat and sound insulation will be at least halved.
In addition, special ecowool equipment- pneumatic installations. The price of such an installation also refers to the disadvantages of using ecowool. Only professional installation using special equipment can guarantee a high result.
For many people, a serious obstacle to the installation of ecowool is the fear of the dangers of lead and boric acid. And although they are indeed contained in ecowool, their toxicity is excluded, and they are not harmful to humans. Boric acid is only harmful to rodents - they feel bad in such an environment and try to leave it as soon as possible.
Of course, the question of its use for each is decided individually. To make a decision, you should not only analyze the advantages and disadvantages well, but also soberly assess your capabilities.
Take into account the price of equipment and material. Assess installation options. In general, competent installation of ecowool will ensure its long and high-quality service.
If you neglect the installation rules and necessary equipment, the result may be unpredictable. To install or not to install - everyone decides for himself.
If we talk about the opinion of real users, then ecowool reviews boil down to the fact that heat and sound insulation is good with appropriate installation. In addition, many build equipment for it on their own, for more low price. Ease of transportation is noted.
In contrast, many are afraid of its toxicity, which is not true, as was written above. Some note that it sags over time, especially on vertical surfaces. There are also users who claim that fire-fighting impregnations simply do not work, because the basis of ecowool is paper.
Methods for the manufacture of ecowool and its installation
First of all, it is worth talking about the manufacture of ecowool. This can be done at home, but do-it-yourself ecowool will be inferior to the original in quality, so you can use it only for personal purposes.
Manufacturing technology is simple. It will take only a few kilograms of waste paper and a powerful shredder (shredder). Shredding paper is half the battle. Next, you should take care of its fire resistance by applying a layer of refractory agent.
Installation of ecowool is mainly carried out by blowing or blowing onto the surface mechanically or manually. It can be used dry or wet ecowool.
For hand laying, since the material is compressed, it must first be “fluffed up” with a drill with a nozzle for stirring the paint. Then for insulation vertical surfaces between the lags the material itself is poured.
Then it must be evenly distributed and well compacted. However, this method is only suitable for insulating the ceiling and floor using dry ecowool.
mechanical method involves the use of a blow molding machine using wet, dry or wet-glue ecowool. The dry method involves bringing the sleeves of the machine to the opening, through which cellulose insulation is supplied with the help of air.
After reaching the desired density in the cavity, the sleeve is disconnected, and the hole is sealed. This procedure is fast, but it sprays a large number of dust.
The wet method is used when it is necessary to insulate vertical surfaces. Before use, ecowool is moistened and applied using a blow molding machine between pre-prepared frames. At the same time, it can dry for a long time, but you do not need to wait for drying, you should cut off the excess in advance.
Wet-glue method is needed for warming vertical surfaces. The technology is the same as with wet ecowool, except for the addition of glue to it for greater adhesion to the surface.
For warming eco-wool roof the same technology is used, only you first need to equip the so-called "roofing pie".
