Fibrololit, - What is it? What is fibrololite? Properties, characteristics, types and price of fibrolite Plates from lightweight cellular concrete or fibrolite

Wood, like raw materials for the manufacture of building materials, use time impertons. The technologies are complicated, the components change, but no artificial material has been able to catch up with the wood or by the price. Since the 20s of the 20s of the twentieth century, in Europe, they thought over the release of interesting, but difficult in the manufacture of plates at that time, WOOL CEMENT Board.

Fibrolite plates what it is

As you can guess from the name, the plates were performed from the so-called wood wool with the addition of cement of different brands. Time went and the technology was improved, but about WOOD Wool Cement Board slab undeservedly forgotten. And only recently the Dutch company Eltomation BV began the release of plates on old technology on new progressive equipment.

The composition of the fibrolite plate is simple. It is made from this very "wood wool"on the portland cement M500 and add a small percentage of liquid glass. Wood chips have a length to half a meter, therefore it is called wool, and the complexity in the production of high-quality plates is that the vehicle is evenly impregnated with the cement solution. This can be achieved only on special equipment for wetting and uniform laying of fibers in a certain order, as well as the formation of finished plates of a given standard size.Fibrolite plate price which is specified in the table, only gains popularity, but when planning construction or repair it is worth it in mind and this material.

Plate manufacturing technology

It would seem that the technology of manufacturing a fibrolite plate is not more difficult to knead the concrete solution. However, it is necessary to compare the characteristics of the corporate Dutch plates and homemade chip blocks, not to mention the appearance of the finished material, as it becomes clear that at each stage of the production of the place there is a thorough control of all parameters. Laying of wood chips is carried out strictly in the horizontal plane to be able to control the density of the finished plate. The width of the fiber is also subject to control and it must be from one to 4 mm depending on the desired plate density, and the chip thickness ranges from 0.2 to 0.5 mm.

Such accuracy and scrupulousity is needed in order to minimize the number of portland cement, but it does not lose the desired strength and density. To do this, it is necessary to organize a uniform impregnation of fibers along the entire length. Strictly observing these parameters, you can make plates with different characteristics of thickness and strength on the same hardware.

Characteristics and scope of application

Depending on the density, the plates can have a different application. Their characteristics are governed by the International Standard and Gosst RF 8928.81. Based on the European experience of mastering fibrolite slabs, the largest percentage of material goes to the devicefailure formwork, about 40%, about 30% of the material is consumed on frame construction, the rest of the fibrolite plates can be used for the partition device, roofing, the manufacture of SIP panels.

When choosing a fibrolite plate, it is important to take into account its density, and the material with different density can be used as follows:

Low density fibrolite sheets are used as thermal insulator, construction heat insulator, as well as acoustic material, but the relative humidity in the room should not exceed 76%.

For rigid sound insulation and non-removable formwork, medium density plates are used.

Highly cute panels are used as carrying structural material, for the device of temporary structures and fences, as well asfor floors.

Features, Advantages and Restrictions

Actually, based on the characteristics of the material, its scope of application is quite understandable. Our plates are used mainly for monolithic construction as a non-removable formwork, regardless of the floors. The non-removable formwork is built as whole houses from fibrolite plates and separate foundations, socles, walls. The stove is light enough, which allows you to do without the use of lifting mechanisms, but it is not harder than wood of medium hardness.

Formulating the main advantages of the material, it is worth noting the most important:

fire resistance, the material does not support combustion;

resistance to biological threats;

low thermal conductivity;

high degree of sound insulation;

long period of operation, about 50 years;

low cost;

easy installation and high speed of construction work.

Despite this, the material has some restrictions on application and disadvantages. If the slab will be in the zone of frequent change of temperature and humidity, it can over time to lose its characteristics, so the fibrolite plate does not leave without external trim. The material is somewhat heavier than wood in volume expression, however, it is easier concrete five to six times, it depends on the density.

Thus, if you correctly apply a fibrolite slab and use all its advantages, it can live efficiently and for a long time at a sufficiently small cost. Successful choice and successful construction!

Fibrolite plates are a chip insulation, which has recently become very popular in the building materials market due to expanding the scope of its application. To understand what it is, it is necessary to familiarize yourself with the composition of the material and its advantages.

In fact, fibrolite plates appeared very long ago, but the production process of modern product is significantly different and has a number of quality characteristics.

How Materials are produced

In the process of producing fibrolite, blending wood chips with water and other components occurs. At the same time, there is a need to impregnate chips with liquid glass or diluted stationery. It is necessary in order to prevent the chemical reaction of wood chips and cement.

At the initial stage, wood wool, which is one of the components of the material, impregnate the astringese composition. In this case, the chips take about 60% of the volume of the plate. Cement composition (40%) is the binder element. Next, the material is poured with cement and pressed in forms, the length of which is about 3 m, and the width of the half-meter to 1, 2 m.

Characteristics of plates

Due to the high operational characteristics of the fibrolite, in the construction world, the material is used widely. Technical features should be allocated:

The material can be called fireproof, despite the large percentage of wood included in its composition. Special impregnation of astringent substances provides this property.
Thanks to the special composition of impregnation, the material perfectly withstands the test of moisture.
Wood wool and cement shell are included in the plates provide fibrolity strength due to the negative impact of deformations and movements.
The composition of the slabs does not allow them to rot or infamous insects.
Benefits should be attributed to high sound insulation capacity.
The material is considered environmentally friendly.
Perfectly withstands the test of low temperatures.
The duration of operation of the plates is about 50 years.
Considering the small weight of the material, their transportation is much easier, without requiring the presence of heavy equipment.
In the process of working with the material, you can use the tools that are suitable for working with wood.
Large product size allows you to install at high speed.
Low price compared to analogues.

Where the material is used

The wood chips included in the fibrolite plates guarantees a high bearing capacity of the material, as well as strength during operation. It is thanks to these features that fibrololite is often used in monolithic construction, as well as playing the role of a non-removable formwork.

In the process of building a low-rise home, fibrolite plates are used as a non-removable formwork.
In residential premises, it is perfectly suitable as a heater for the floor, inter-storey overlap and ceiling.
In a frame building as a finishing trim, which is subsequently decorative.
Material has excellent sound insulation characteristics.

It is worth noting that the plates may differ both in terms of density and size, depending on the scope of use.

Material in which low density (about 570 kg / m3) is used as a sound insulation material. Sometimes as insulation.
A product that is distinguished by an average density (up to 800 g / m3) is used as fencing structural elements.
Sophisticated fender structures that are distinguished by a high bearing capacity require a material that has a high density (from 1400 kg / m3).

In the process of acquiring the material, it is important to pay attention to the labeling. For example, if there is a F500 label on it, this suggests that its density ranges from 500 kg / m 3.

Monolithic construction and fibrololite

In the construction of a monolithic design, costs can be reduced by preferred fibrolite plates, which are used as a non-removable formwork. In addition, there is not only a decrease in labor intensity, but the question of the insulation of the house is solved.

If the work occurs at low temperatures, the formwork from the fibrolite will become the best option. At the same time, concrete needs additional warming, which leads to additional spending.

It is worth understanding that with the help of stoves it is possible to build both rectilinear and curvilinear monolithic structures. To work, you need to cut down the plates on the details of the desired size and lay the formwork, adhering to the project.

Fibrololit will be the best option in metropolis, where different sounds and noise deliver a lot of discomfort. The unique cellular structure of the slab struggles with high-frequency sounds. Thus, it is possible to apply them for walls, gender and ceiling.

Video

Look at the cognitive video about fibrolite plates:

Fibrolite plates are multifunctional building material based on wood chips. Fibrololit has many beneficial properties of natural wood, but in contrast to the wood, fibrololite is resistant to the effects of fire and is not subject to rotation processes.

For the first time, fibrolite plates began to develop at the beginning of the last century. Initially, they were made of chips, sawdust, chips and various other waste of the woodworking industry. The first fibrolite plates were characterized by good heat and sound insulation, but possessed extremely low strength. Over time, the technology of production of fibrolite slabs was noticeably improved.

The composition of modern plates includes thin wood wool made of soft wood. The binding element is cement, liquid glass or caustic magnets. Magnesite-based fibrolite plates are considered the most environmentally friendly and at the moment there are no analogues in the world.

Fibrolite plates in principle can not be called a new building material. The technology of using cement and wood chips is known for a long time, including the production of fibrolite. In addition to fibrolite plates there are still CSPs, in which chips and cement also applies, but chopped chips (chips).

Technologies are changing towards improving. Standards released at the time of the union, which still enjoy, morally obsolete, and the material acquires new properties and applications. It fully applies to fibrolite plates.

Fibrolite plates History

The current GOST on this group of products has the editorial board of 81 years. It has been developed by the relevant Ministry of the USSR. In accordance with its norms, fibrolite plates with three stamps, determining the characteristics of the material:

F-300 (averaged density during scattering 250-350 kg per cubic);
F-400 (351-450);
F-500 (451-500).

The first type of thermal insulation, the second - heat-insulating-structural, in the third place in the first place structural properties, it is also named - structurally thermal insulation. In addition, the F-400 and F-500 are used for sound insulation. The standard stipulates dimensions, strength, water absorption and other characteristics.

Modern manufacturers went further: they expanded the plate density range, and therefore, the scope of use. You can say, they more clearly outlined the boundaries The density and size of the plates are different, it depends on where they will be used:

Material with a low indicator is more often used as a sound insulation material.
Plates having an average density mainly for fencing.
For the construction of complex structures requires fibrol with a higher density.

As a visual example, it is worth bringing the plates produced on the equipment of the Dutch company ELTOMATION. They classify low-density slabs in the entire range of domestic standard, and in addition they produce two more categories of plates: with a density of 600-800 kg / cube. m. and up to 1100 kg / cube. m.

Plates with a trademark Green Board are classified three brands - GB1 (density 250-570), GB2 (600-800), GB3 (1000-1400).

Already according to the characteristics of the density, it can be seen that in addition to the field of use specified in the domestic standard, brands were added, which can be used as structural and finishing materials. It would be possible to argue: why invent something new for enclosing surfaces and cladding, because there are plywood , Chipboard and OSP, which have high strength characteristics. But fibrolite plates have a number of advantages in front of them.

Fibrolite dignity plates

Fibrololite as a thermal insulation material is inferior to polystyrene foam or mineral wool, but it is practically not used in its pure form as the insulation. If you evaluate statistics, then 40% of the market consumption in the market and we have, and in Europe falls on a non-removable formwork. And in this capacity, the fibrolite has a significant advantage over polystyrene foam - it is non-combustible (class T1) and has breathable properties.

Environmental Safety
Fibrolyt has excellent environmental properties. It does not highlight harmful toxic substances and is absolutely safe for humans.

Durability
Fibrolite is not deformed, not subject to the devastating effects of insects, rodents, mold, fungi and other microorganisms.

Good thermal insulation
Wood for a long time is famous for its heat shielding properties. Fibrololite, as well as natural wood, retains warmth well.

Increased water resistance
Fibrololit has a high level of waterproof. Fibrolite plates can be installed in rooms with humidity up to 75%. In rooms with higher humidity, fibrolite plates are recommended to protect against damp with plaster or waterproofing.

Fire safety
Fibrolit has a very high resistance to fire

Since the characteristics of the plates are high, its use in the construction sphere is very high. The production of fibrolite plates has existed for many years, but over time the process has undergone significant changes, and the material has become better. Let's summarize the merits, the material has the following technical characteristics:

Fireproofing. Thanks to the astringent impregnation, the woody product becomes capable of such a property.
Moisture resistance. Again, due to the impregnating layer, the material perfectly copes with water getting.
Strength. This quality fibrolit is obliged to wood and cement layer.
Resistance to rotting and pests.
Increased sound insulation.
Environmental purity.
Excellent cool temperatures.
Long period of operational period.
Simplicity of transportation. Since fibrolite does not have a lot of weight, it will not be necessary for this heavy machinery.
Ease when installing.

The rest of the market falls on panel-frame (20%) and panel (40%) construction. Compared to plywood OSP and chipboard, fibrolite plates do not contain phenolic resins, so they won in environmental friendliness.

Breathable properties and ability to self-regulating moisture (absorption during an excess and return with a deficiency) provide maintenance of comfortable living conditions. And of course, an important indicator is high fire safety.

General advantages as building materials - high durability, water resistance (wood "connected" mineral additives), good adhesion with construction mixtures (plaster, putty), primers and paints.

Where are fibrolite plates used?

Fibrolite plates have standard sizes and low weight, so it is possible to work with them without the involvement of heavy lifting techniques. Fibrolite plates are also actively used for insulation and noise insulation of internal and outer walls, inclined roofs, attics, interior partitions and inter-floor floors.

Since the production of material is added wood chips, the strength is significantly increased, so fibrololite is often used during monolithic construction of buildings. In addition, it is used:

with low-rise construction of houses as a formwork;
in quality when laying the insulation layer;
as a finishing, the finish will continue to be in the future;
as sound insulation.

The use of fibrolite plates in the construction of a monolithic type

Cutting costs during the construction of a monolithic house is possible due to the fibrolite, from which the non-removable formwork is built. These designs are convenient in the installation, in addition, it is possible to resolve the issue with housing insulation. Fibrolite plates are often used in the construction of panel-frame houses. Due to its structural properties, fibrolite plates are ideal for the construction of a non-coordinate formwork.

Fibrolite plates are used to build various design options. To do this, take out the cutting material on the necessary dimensions, further, according to the project, the formwork is stacked.

The use of fibrolite is most appropriate in the context of the city, since it will protect against noise that delivers considerable discomfort.

Manufacturing technology and composition

The process is to mix wood shavings with water base and some additives. To do this, liquid glass or stationery adhesive in the diluted state is added to the chips. It is necessary that a chemical response does not occur between the components.

Initially, the impregnation of wood wool is impregnated, for this, a special binding mixture is used. As a bundle, the composition is made of cement. After that, fill and pressing the material in the form.

Such high properties are laid by the composition, structure and technology of manufacturing. Fibrolite by 60% wood, by almost 40% cement, also in the composition of no more semi-loan mineral additive. Three main factors can be distinguished, they distinguish a fibrolite slab from other wood-based materials:

at the first stage - the manufacture of especially fine and long chips, which is called wood coat;
on the second - the mineralization of wood (for example, liquid glass) to "close" to the wood access of water;
in the third stage - horizontal orientation of wood wool in the process of manufacturing the plate.

Tree and cement - environmentally friendly materials. Mineralization protects against humidity. The structure of the slab provides sufficiently high strength on the break. Adjusting the density of the slab, achieve a certain set of major operational properties - thermal insulation, sound insulation, structural strength.

There are many other advantages of fibrolite compared to other building materials. Despite the fact that fibrololite is a relatively young building material, thanks to its unique properties and low cost, it is becoming more and more widely used in modern construction practice. Watch the video:

Fibrobloka

Fibrololite (FB) is a building material used in the construction of a non-removable formwork, monolithic foundations, walls. Fibrolite panels are also used for the insulation of facades, overlaps, etc. The main features of the material are low weight, good heat and sound insulation properties.

Structure

Fibrolite plates are used in construction from the end of the 20s of the XX century. According to the composition of the product similar to the arbolit. The difference lies in the sizes. In Arbolit, wood waste grinding into a small crumb. The fibroplite contains chips as a binder filler in the form of a ribbon longer than 350 mm, 5-10 mm width.

Plate manufacturing is a simple technological process. The wood material is treated with potassium chloride. The mineralizer uses liquid glass and sulfur alumina. Then the chips is stirred with cement mortar, pressed in special forms. After thermal exposure, drying to the level of humidity of 20% is obtained by finished products.

Specifications

The standard stove has a length of 240 or 300 cm, a width of 60 or 120 cm, a thickness of 3-15 cm. Many manufacturers produce plates and other sizes: 3000 × 600, 2700 × 1250, 3200 × 1250 or 3600 × 1200 mm, thickness 10, 25 , 50 mm.

In stores, Fibrolite products are sold under the name "Cement-chipsticks (CSP)". Depending on the density of the material in a dry form, they are divided into several stamps. FB characteristics are presented in the table.

Dignity

The advantages of building materials from fibrolite:

FB is not subject to open burning;
plates can be easily sawing, drilled, punch with nails;
the dowels are firmly fixed in the FB massif;
the rough surface provides high adhesion to plaster;
low weight;
the use of FB as a fixed formwork of foundations, walls significantly reduces construction time, labor costs;

easy installation of fencing facing provides fast work.

Disadvantages of Fibrolita

Cons of the use of material:

despite moisture and biostostility, the installation of plates should be avoided in high humidity conditions;
the cyclicality of freezing and thawing significantly reduces the service life of the material;
FB is 20% heavier dry wood, 4 times easier monolithic concrete.

Main applications

Cement-chipboards are used to insulate the foundations, walls, overlaps and roofs of buildings.

Foundation Foundation

When the monolithic foundations are erected, the panel formwork is first installed. After soaring the concrete, it is dismantled. Then the foundation is insulated. The work costs somehow, takes a lot of time. The device of enclosing structures from fibrolite panels solves these problems.

The thickness of the CSP is determined by the estimated path. Fiberglass formwork technology does not cause special difficulties. Works are produced in several stages:

Inside the trenches on the cement-sand pillow in two rows put the CSP. The distance between the plates is equal to the calculated width of the monolithic ribbon.
Inside the panels are placed by reinforcement.
At the top of the fibrol is fixed by segments of a wooden bar, which nail to the plates with nails.
In the case of a device of thick walls in the middle of the height of the CSP, they put spacer metal studs.
Produce the fill of the foundation concrete with layer-by-layer traam.
The outer surfaces of the formwork are treated with liquid bitumen or coated with another waterproofing.
After 28-30 days, the insulated base of the building is ready to further build.

Heat float

Concrete floors are insulated mainly over unheated basement, in attic floors. This happens as follows:

On a clean, dry concrete base laid fibrolite plates.
Seams between sheets close up with cement.
On top of the insulation, the cement-sandy solution is performed. Its thickness usually ranges from 30 to 50 mm.
After the dialing of the strength, the flooring is placed: linoleum, laminate or tile.

Wall insulation

Walls insulate fibrolite most often from the inside of the building. Sometimes they do on the facade of the house. Perform this work like this:

For insulation, the perforator, saw and hammer use. If the facade is insulated, the forests or scaffolding are installed.
In advance, outline FB sheets are attached to the walls of fungal dowels. To do this, drill a perforator panel and walls. In the holes are clogged with a hammer of a dowel.
Plastering walls. On the facade - a solution with moisture-resistant additives.
After drying, the layer is embarking on the finish finish of fences.

Hearth roofing

Scope roofs insulate from the inside. Works are performed in the following order:

In order to avoid the formation of the slots, the rafters are trimmed by cutting boards.
Fibrolite panels are prepared by handing them with a saw.
Put wood facing with plates with a thickness of 10 mm. Fasten the FB to shurupa's boards.
The finish finish is performed by sheets of fiberboard or other material.

The cost of fibrolite plates

Prices for typical dimensions of fibrolite sheets are specified in the table.

Fibrolite plate size, mm	Price per 1 pc., Rub.
3200 × 1250 × 10
3000 × 600 × 25
3600 × 1200 × 10
2700 × 1200 × 10
2800 × 600 × 50
2800 × 600 × 100

Today, increasingly preferred is given to multifunctional materials that make several functions at once simultaneously. Fibrolite plates whose characteristics can be rightfully called impeccable - this is a universal material used for both facing floor, walls and for heat insulation of the room, the construction of partitions and even the construction of a non-removable formwork.

Properties and characteristics of fibrolite plates

Fibergolite stove, the production of which is regulated by GOST 8928-81, the main binder contains portland cement, which accounts for about 40% in the composition.

Mixed cement with filler in the form of wood conifer chips, called still wood wool. The length of the chips can reach 5 cm, and the thickness is 5 mm.

The share of wood wool accounts for about 60%. Its main goal is to reduce the weight of the material and ensuring low thermal conductivity.

Also, chemical additives are added to the resulting mixture of chips and portland cement, calcium chloride, lime chloride, etc. The direct manufacture of material is carried out by pressing.

Views

Fibrolite plates GOST 8928-81, depending on the scope of application, classified on the brand:

F-300. Found their use as a heat insulator.
F-400. Recommended for sound insulation and facilities of heat-insulating-structural partitions, barriers, etc.
F-500. Used as sound insulation and structural heat-insulating materials.

The degree of density and strength serve as a reason for the following gradation:

GB1 - low-density fibrolite plates,
GB2 - with medium density and strength indicators;
GB3 - with high density and strength indicators;
GB4 - combined (layered) fibrolite stove, the production of which is carried out by alternating the layers with high and low density;
GB1L - endowed with minimal density values;
GB3F - FIBROT combined type with high density indicators, additionally re-plated.

Comparison by Markama

Fibrolite plates Characteristics have several excellent among themselves, distinguished by brand:

Fibrolite plates whose price ranges from 390 to 2000 p. Depending on density and sizes, have standardized geometric parameters.

The length can be 240 and 300 cm, the width is 60 and 120 cm, and the thickness - 3, 5, 7.5, 10 and 15 cm. However, GOST 8928-81 allows the production of products with other parameters previously agreed with the consumer. Therefore, heavy-duty samples with a density of 600, 900 and even 1050 kg / m 3 can be found on sale.

Advantages of fibrolite plates

A special role is played by the ability to soundly insulated the room. Fibrololite allows several times to reduce the intensity of incoming and outgoing noise. Moreover, it is capable of protecting households not only from shock noises, but also a air noise effect.

Along with this, fibrolite plates are distinguished by heat-saving characteristics due to the low thermal conductivity coefficient, fluctuating in the range of 0.08-0.1 W / (M ∙ K).

Thanks to this property, the material can be used as a good complementary means to an existing heating system with the ability to reduce heating costs.

Fibrolite plates, the use of which is possible both for outdoor and internal use. The material is easy to mechanically process, which greatly simplifies the task to the home master and reduces the time of repair work.

In addition, high strength to bend allows you to easily build interior partitions. And their lightness, in comparison with concrete, facilitates work and does not create an additional heavy load on the walls.

The main advantage of fibrolite in comparison with shuppo-cemental counterparts is a large moisture resistance. The fibrolite plate may be unlimited times to be exposed to moisture, wet and fast enough, retaining the structure.

https://youtu.be/b6ggckjxiwk.

Fibrolitic stove, the production of which is not characterized by the use of harmful phenolic or formaldehyde resins, refers to environmentally friendly materials. It has high fire resistance, refers to hard-fired materials.

Fibrolitis awarded classes of G1, B1, T1, D1, RP1, which speaks of weakness, so-flammability, non-toxicity with minimal smoke-forming ability and disability to disseminate the flame.

Another feature is the possibility of regulating humidity in the room. Such an effect is achieved due to the loose structure of the material absorbing excess moisture and the giving moisture with its disadvantage. Thereby, there is a comfortable microclimatic conditions. The service life can reach 60 years.

On the fibrolite plates, the price is in most cases cases even lower than the value of the current internal finishing materials (in particular, GLC, chipboard, fiberboard, SML, OSB, etc.).

disadvantages

Fibrololit has several drawbacks:

Exposure to fungi when using material in excessively wet rooms. The recommended moisture value for the use of fibrolite is 75%.
Relatively large mass, in comparison with wood plates or plasterboard. The weight of the slab fluctuates from 12 to 55 kg, depending on the density and geometric parameters.

Fibrolite plates, the use of which is not limited to internal use, an excellent alternative to the usual plasterboard and chipboard. At the same time, the set of technical characteristics of the fibrolite is not only inferior, but, on the contrary, exceeds the indicators of GLC, chipboard and fiberboard.
