Fiberboard slabs: properties, prices, pros and cons, reviews of the owners of houses from fiberboard. Fiberboard - material features and scope Cement fiberboard

Today, more and more preference is given to multifunctional materials that perform several functions at once. Fiberboard, the characteristics of which can rightfully be called impeccable - these are universal material used for both floor and wall cladding and heat and sound insulation premises, construction of partitions and even erection fixed formwork.

Properties and characteristics of fiberboard boards

Fiberboard, the production of which is regulated by GOST 8928-81, contains Portland cement as the main connecting element, which accounts for about 40% of the composition.

Cement is mixed with a filler in the form of coniferous wood shavings, also called wood wool. The length of the chips can reach 5 cm, and the thickness is 5 mm.

Wood wool accounts for about 60%. Its main goal is to reduce the weight of the material and provide low thermal conductivity.

Also, chemical additives in the form of liquid glass, calcium chloride, lime, etc. are added to the resulting mixture of chips and Portland cement. The direct production of the material is carried out by pressing.

Kinds

Fiberboard slabs GOST 8928-81, depending on the scope of application, are classified into grades:

F-300. Found their application as a heat insulator.
F-400. Recommended for soundproofing and construction of heat-insulating and structural partitions, barriers, etc.
F-500. They are used as soundproofing and structural and heat-insulating materials.

The degree of density and strength gave rise to the following gradation:

GB1 - low density fiberboard,
GB2 - with average density and strength indicators;
GB3 - with high density and strength;
GB4 - combined (layered) fiberboard, the production of which is carried out by alternating layers with high and low density;
GB1L - endowed with minimum density values;
GB3F is a combined fiberboard with high density, additionally decorated with a coating.

Brand Comparison

Fiberboard characteristics have slightly different characteristics, distinguished by brand:

Fiberboard plates, the price of which ranges from 390 to 2000 rubles. depending on the density and dimensions, they have standardized geometric parameters.

The length can be 240 and 300 cm, width - 60 and 120 cm, and thickness - 3, 5, 7.5, 10 and 15 cm. However, GOST 8928-81 allows the release 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 also be found on sale.

Advantages of fiberboard boards

A special role is played by the ability to soundproof the room. Fiberboard allows several times to reduce the intensity of incoming and outgoing noise. Moreover, he is able to protect households not only from impact noise, but also air noise effect.

Along with this, fibrolite boards are distinguished by their heat-saving characteristics due to the low coefficient of thermal conductivity, which ranges from 0.08-0.1 W / (m∙K).

Thanks to this property, the material can be used as a good supplement to already existing system heating with the possibility of reducing heating costs.

Fiberboard boards, the use of which is possible both for external and internal use. The material is easy to machining, which greatly simplifies the task. home master and reduces repair time.

In addition, high bending strength makes it easy to build interior partitions. And their lightness, in comparison with concrete, facilitates the work and does not create an additional heavy load on the walls.

The main advantage of fiberboard in comparison with wood-cement analogs is its high moisture resistance. Fiberboard can be exposed to moisture an unlimited number of times, getting wet at the same time and drying quickly enough, retaining the structure.

Fiberboard, the production of which is not characterized by the use of harmful phenolic or formaldehyde resins, belongs to environmentally friendly materials. It has high fire resistance, refers to slow-burning materials.

The fibrolite was awarded classes G1, V1, T1, D1, RP1, which indicates low combustibility, low flammability, non-toxicity with minimal smoke generation and inability to spread flame.

Another feature is the ability to control the humidity in the room. This effect is achieved due to the loose structure of the material, which absorbs excess moisture and releases moisture when it is deficient. Thus, comfortable microclimatic conditions are established. Service life can reach 60 years.

For fiberboards, the price in most cases is even lower than the cost of the currently popular internal finishing materials(in particular GKL, chipboard, fiberboard, LSU, OSB, etc.).

Flaws

Fiberboard also has several disadvantages:

Susceptibility to fungal attack when using the material in excessively damp areas. The recommended humidity value for fiberboard application is 75%.
Relatively large mass, compared to wood-based panels or drywall. The weight of the plate ranges from 12 to 55 kg, depending on the density and geometric parameters.

Fiberboard, the use of which is not limited to internal use, great alternative the usual drywall and chipboard. At the same time, the set specifications fibrolite not only does not concede, but, on the contrary, surpasses the indicators of GKL, chipboard and fiberboard.

Fiberboard slabs are a heater used in the construction of buildings and structures, as well as in interior decoration. This wood chip material has become very popular in Lately, which was made possible thanks to enough low prices on products and numerous advantages. In the article, we will take a closer look at where such a heater can be used, learn about its key features, forcing consumers to make a choice in favor of fiberboard.

Fiberboard slabs - general information about the material

Fiberboard - what is it? Along with modern artificial materials suddenly appeared new material for warming the room. In fact, this insulation has been known for a long time, because more than a century ago people used similar plates, creating them manually from clay, straw and bricks. We can safely say that fiberboard is an ideal confirmation of the phrase that everything new is a well-forgotten old.

The name of the product has its origins in Latin. Literally, the word "fibrolite" can be translated as "fibrous stone". It is unlikely that it will be possible to more accurately describe a plate made of fiberboard. It is environmentally friendly and safe material, the production of which is carried out from several main components - high-grade Portland cement, liquid glass and natural wood shavings. Easy to manufacture and use, as well as very practical, the panel is gradually conquering the construction market, because the material has many advantages, while its price pleasantly surprises.

Each component from which fiberboards are made deserves a more detailed explanation:

1. Portland cement - in this context, cement plays a role binder. In percentage terms, it accounts for exactly one third. Cement is necessary here to give the plates such important properties as strength, strength, reliability, wear resistance. The material must not only serve for a long service life, but also retain all its qualities during delivery, transportation, and storage.
2. Wood chips or wool - the basis of the plate. Its share is almost two thirds of the total volume of the plate. In production this insulation leading companies use natural wood shavings up to 5 cm long and 3-4 mm thick. The use of wood chips is necessary to increase the level of thermal conductivity of the coating.
3. Liquid glass is a kind of diluted clerical glue, which is scientifically called low concentration sodium silicate. The main task of liquid glass is to isolate wood shavings from moisture. As a result, fiberboard can cope with increased levels of humidity. True, only for a short period of time. Long-term operation of the heater in conditions high humidity may lead to its destruction.

Fiberboard - the main types and scope

Today, fiberboard insulation is widely used in various fields of construction. However, most often this material can be found in fixed formwork in monolithic housing construction. Repair and reconstruction of buildings and structures, as well as construction multi-storey buildings rarely does without fiberboard plates.

The reason is that fixed formwork made of fiberboard is the most economical, fastest and in a simple way building construction. The small weight of the plate, as well as their standard dimensions, allow you to work even without the use of additional lifting equipment. Among other things, it is very simple to work with plates; even a person inexperienced in the art of building can finish the room with fiberboard.

Processing is almost the same as processing ordinary tree, the same applies to the necessary tools in the work. As practice shows, the use of wood-chip insulation with the addition of cement as a fixed formwork allows several times to reduce labor costs and time for the construction of structures.

Fiberboard is often used for the construction of fixed formwork.

Note that depending on the scope of application, fibrolite boards may differ in the density of the material structure, as well as in size. The following are the most popular brands of goods that are widely used by modern craftsmen:

Fiberboard with low density (570 kg/m3) is an excellent insulation that can be used as a sound insulator when finishing interior spaces in a private house or apartment
Material with an average density (800 kg / m3) - such a product is more often used as enclosing structural elements, although it is also great for soundproofing
Plates with high density (from 1400 kg/m3) have found application in complex protective structures where a high bearing density of the material is required.

Fiberboard slab can be used in construction even if low temperatures, which is associated with the excellent performance of the product in terms of thermal insulation. This also makes it possible to significantly reduce the costs associated with heating concrete during construction during cold periods. In addition to thermal insulation, the plate is distinguished by soundproofing qualities. The use of the material as an insulator allows you to improve the level of sound insulation in any room of your apartment. Fiberboard does not creak and does not deform under heavy loads, even for a long time, due to which it is very often used as a substrate floor coverings for linoleum and even ceramic tiles.

Modern fibrolite boards boast excellent moisture resistance, due to which they can be used in rooms and premises with humidity up to 75%. Unfortunately, not all grades of fibrolite differ in similar indicators, moreover, the cost of moisture-resistant material is an order of magnitude higher than conventional goods.

Why fiberboard has become popular - the advantages and disadvantages of the product

Despite the fact that the insulation produced on the basis of wood chips, cement and liquid glass has only recently appeared on construction market, he has already managed to become one of the most popular and sought-after heaters and insulators. This is facilitated by a huge number of positive aspects, the most important of which are:

Environmental safety of products - two-thirds of the fibrolite consists of natural wood which already says a lot. Cement, like glass, does not emit harmful and toxic substances, so you can safely finish the premises in the apartment without the risk of harming your family and friends.
Durability - long service life is ensured by the optimal combination of impact-resistant cement and elastically deformable wood chips. The market for synthetic building materials will no longer be able to offer similar products with the same performance.
Resistance to deformation and movement - again, everything is provided by the right ratio of cement and wood, where cement gives the product the necessary strength, while wood wool plays the role of a kind of damper.
Sound and thermal insulation - standard fiberboards of the required thickness will completely dampen noisy neighbors while creating a comfortable temperature in the room.

This is not all the advantages of the material, because one can also note such important qualities as the ease and convenience of laying plates, a small coefficient of expansion of the plate, and much more. It is not surprising that consumers are trying to purchase exactly fiberboard insulation, because with a huge number of advantages, the product has very affordable prices.

However, there are also some disadvantages that cannot be ignored:

1. As already noted, slabs do not do very well with high humidity because it contains wood. In addition, constant temperature fluctuations can adversely affect the quality of the product, accelerating the deformation of the plate, which in the future can lead to its complete destruction.
2. Another problem arising from the presence of wood in the composition is the susceptibility to mold and other fungi. During the initial laying, it is necessary to thoroughly dry the surface on which the slab will lie. The fibrolite itself can be treated with various antiseptic compounds, which will increase the service life of the material.
3. Weight of fiberboard panels - this factor can be considered from different points of view. For example, ordinary wood-based panels have a slightly lower weight, but compared to other building materials, including concrete, fibrolite is about 4 times lighter. This eliminates the use of various special equipment to work with heavy loads at a construction site.

So feel free to buy fiberboard insulation. It will please you with a long service life, as well as many positive qualities, which completely outweigh some negative sides. In addition, the price is very low compared to other materials, which is an absolute plus.

Fiberboard is a wood-chip insulation, which has recently become very popular in the building materials market due to the expansion of its scope. To understand what it is, you need to familiarize yourself with the composition of the material and its advantages.

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

How the material is produced

During the production of fiberboard, wood chips are mixed with water and other components. At the same time, there is a need to impregnate the chips liquid glass or diluted stationery glue. This is necessary in order to prevent chemical reaction wood shavings and cement.

At the initial stage, wood wool, which is one of the components of the material, is impregnated with a binder. In this case, the chips occupy about 60% of the volume of the plate. The cement composition (40%) acts as a binding element. Next, the material is poured with cement and pressed into molds, the length of which is about 3 m, and the width is from half a meter to 1.2 m.

Characteristics of plates

Thanks to high performance characteristics fiberboard, the material is widely used in the construction world. It is necessary to highlight the technical features:

The material can be called fireproof, despite the large percentage of wood that is part of it. Special impregnation with binders provides this property.
Due to the special composition of the impregnation, the material perfectly withstands the moisture test.
The wood wool and cement sheath included in the boards provide strength to the fibrolite, due to the negative effects of deformations and movements.
The composition of the plates does not allow them to rot or become infected with insects.
The advantages include high soundproofing ability.
The material is considered environmentally friendly.
Excellent resistance to low temperature test.
The life of the plates is about 50 years.
Given the low 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 tools that are suitable for working with wood.
The large size of the product allows installation at high speed.
Low price compared to analogues.

Where is the material applied?

Wood shavings, which is part of fiberboard boards, guarantee a high load-bearing capacity of the material, as well as durability during operation. Due to these features, fibrolite is often used in monolithic construction, as well as playing the role of fixed formwork.

In the process of building a low-rise building, fiberboard slabs are used as fixed formwork.
In residential areas, it is excellent as a floor insulation, interfloor overlap and ceiling.
In a frame building as a finishing sheathing, which subsequently implies a decorative finish.
The material has excellent soundproofing characteristics.

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

A material that has a low density (about 570 kg/m3) is used as soundproofing material. Sometimes as a heater.
The product, which is characterized by an average density (up to 800 g / m3), is used as enclosing structural elements.
Complex protective structures, which are distinguished by high bearing capacity, need a material that has a high density (from 1400 kg / m3).

In the process of purchasing material, it is important to pay attention to the labeling. For example, if it has the F500 mark on it, this indicates that its density fluctuates within 500 kg / m 3.

Monolithic construction and fiberboard

During the construction of a monolithic structure, costs can be reduced by giving preference to fiberboard slabs, which are used as fixed formwork. In addition, there is not only a decrease in labor intensity, but also the issue of warming the house is being solved.

If the work takes place at low temperatures, the fiberboard formwork will become the best option. At the same time, concrete needs additional heating, which leads to additional expenses.

It should be understood that with the help of plates it is possible to erect both rectilinear and curvilinear monolithic structures. To work, you need to cut the plates into parts right size and lay the formwork, adhering to the project.

Fiberboard will be the best option in megacities, where various sounds and noise cause a lot of discomfort. The unique honeycomb structure of the plates fights high-frequency sounds. Thus, you can apply them to walls, floors and ceilings.

Video

Watch an educational video about fiberboard:

Fiberboard is a multifunctional building material based on wood shavings. Fiberboard has many useful properties natural wood, but unlike wood, fiberboard is resistant to fire and is not subject to rotting processes.

For the first time, fiberboard slabs began to be developed at the beginning of the last century. Initially, they were made from shavings, sawdust, wood chips and various other waste from the woodworking industry. The first fiberboard slabs were characterized by good heat and sound insulation, but had extremely low strength. Over time, the technology for the production of fibrolite plates has improved markedly.

Part modern stoves includes fine wood wool from soft woods. The connecting element is cement, liquid glass or caustic magnesite. Magnesite-based fiberboards are considered the most environmentally friendly and this moment have no analogues in the world.

Fiberboard slabs, in principle, cannot be called a new building material. The technology of using cement and wood shavings has been known for a long time, including the production of fiberboard. In addition to fiberboard slabs, there is also a CSP, in which chips and cement are also used, but shavings are crushed (chips).

Technologies are changing in the direction of improvement. The standards issued back in the days of the Union, which are still in use, become obsolete, and the material acquires new properties and applications. This fully applies to fiberboard plates.

Fiberboard history

The current GOST for this group of products has an edition of 81 years. It was developed by the relevant ministry of the USSR. In accordance with its norms, fiberboard plates with three grades are provided, which determine the characteristics of the material:

F-300 (average density with a spread of 250-350 kg per cube);
F-400 (351–450);
F-500 (451–500).

The first type is heat-insulating, the second - heat-insulating and structural, the third has structural properties in the first place, it is called so - structural and heat-insulating. In addition, F-400 and F-500 are used for soundproofing. The standard specified dimensions, strength, water absorption and other characteristics.

Modern manufacturers have gone further: they have expanded the range of plate density, and hence the scope of use. It can be said that they more clearly delineated the boundaries The density and size of the plates are different, it depends on where they will be used:

A material with a low index is more often used as a soundproofing material.
Slabs having an average density, mainly for fencing.
For building complex structures fiber mat with a higher density is required.

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

Plates with the Green Board trademark are classified into three grades - GB1 (density 250–570), GB2 (600–800), GB3 (1000–1400).

Already by the density characteristics, it can be seen that in addition to the scope of use specified in the domestic standard, grades have been added that can be used as structural and finishing materials. One could argue: why invent something new for enclosing surfaces and cladding, because there is plywood , chipboard and OSB, which have high strength characteristics. But fiberboard plates have a number of advantages over them.

Fiberboard Dignity

Fiberboard as thermal insulation material inferior to expanded polystyrene or mineral wool, but in its pure form it is practically not used as a heater. If we evaluate the statistics, then 40% of the share of consumption in the market both here and in Europe falls on fixed formwork. And in this capacity, fibrolite has a significant advantage over expanded polystyrene - it is non-flammable (class T1) and has breathable properties.

Environmental Safety
Fiberboard has excellent ecological properties. It does not emit harmful toxic substances and is absolutely safe for humans.

Durability
Fiberboard does not deform, is not subject to the destructive effects of insects, rodents, mold, fungi and other microorganisms.

Good thermal insulation
Wood has long been famous for its heat-shielding properties. Fiberboard, like natural wood, retains heat well.

Increased water resistance
Fiberboard has high level waterproof. Fiberboard can be installed in rooms with humidity up to 75%. In rooms with higher humidity, it is recommended to protect fiberboard from dampness with plaster or waterproofing.

Fire safety
Fiberboard has a very high resistance to fire

Since the characteristics of the plates are high, its use in the construction industry is very high. The production of fiberboard has existed for many years, but over time the process has undergone significant changes, and the material has become better. To sum up the advantages, the material has the following technical characteristics:

Fire safety. Thanks to the astringent impregnation, the wood product becomes capable of this property.
Moisture resistance. Again, because of the impregnating layer, the material copes well with water ingress.
Strength. The fiberboard owes this quality to wood and a layer of cement.
Resistant to decay and pests.
Increased sound insulation.
Ecological purity.
Excellent resistance to cold temperatures.
Long service life.
Ease of transportation. Since the fiberboard does not have a lot of weight, heavy equipment will not be needed for this.
Ease of installation.

The rest of the market falls on panel-frame (20%) and panel (40%) construction. Compared to plywood, OSB and chipboard, fiberboard does not contain phenolic resins, so they benefit from environmental friendliness.

Breathability and the ability to self-regulate moisture (absorption when excess and return when deficient) provide maintenance comfortable conditions dwellings. And of course, an important indicator is high fire safety.

General advantages as a building material - high durability, resistance to water (wood is "bound" by mineral additives), good adhesion co building mixtures(plaster, putty), primers and paints.

Where are fiberboards used?

Fiberboard has standard sizes and light weight, so you can work with them without the involvement of heavy lifting equipment. Fiberboard is also actively used for insulation and soundproofing of internal and external walls, sloping roofs, attics, interior partitions and intermediate floors.

Since wood chips are added during the production of the material, the strength increases significantly, therefore fiberboard is often used during the monolithic construction of buildings. In addition, it is used:

in low-rise construction of houses as a formwork;
as when laying an insulating layer;
as a finishing sheathing, on which the finish will be applied in the future;
as soundproofing.

The use of fiberboard slabs in the construction of a monolithic type

It is possible to reduce costs during the construction of a monolithic house thanks to the fiberboard, from which a fixed-type formwork is often constructed. These designs are easy to install, in addition, you can solve the issue of home insulation. Fiberboard slabs are often used in construction panel-frame houses. Due to their structural properties, fiberboards are ideal for the construction of fixed formwork.

Fiberboard is used to build various options structures. To do this, the material is cut according to required dimensions, then, according to the project, the formwork is laid.

The use of fibrolite is most appropriate in urban conditions, since it will protect against noise that causes considerable discomfort.

Manufacturing technology and composition

The process consists in mixing wood shavings with water base and some additives. To do this, liquid glass or stationery glue in a diluted state is added to the chips. This is necessary so that no chemical reaction occurs between the components.

Initially, wood wool is impregnated, for this a special binder mixture is used. The cement is used as a binder. After that, the material is poured and pressed into molds.

Such high properties are laid down by the composition, structure and manufacturing technology. Fibrolit is 60% wood, almost 40% cement, also in the composition of no more than half a percent mineral additive. There are three main factors that distinguish fiberboard from other wood-based materials:

at the first stage - the manufacture of especially thin and long chips, which is called wood wool;
on the second - the mineralization of wood (for example, with liquid glass) in order to “close” water access to the tree;
at the third stage - the horizontal orientation of the wood wool in the process of manufacturing the board.

Wood and cement are environmentally friendly materials. Mineralization protects against moisture. The structure of the plate provides a sufficiently high fracture strength. By adjusting the density of the plate, a certain set of basic operational properties is achieved - thermal insulation, sound insulation, structural strength.

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

Deservedly occupied its niche in the building materials market such a product as Green board domestic manufacturer from Vladimir region. Most of the production is wood fiber, which is held together with liquid glass and Portland cement. Such a composition is similar to fibrolite, however, a smaller amount of cement is used here, as well as longer fibers with multidirectional laying, which does not affect strength, but significantly reduces the weight of the web and increases flexural strength. If we talk about all the available positive characteristics, then you can enumerate:

good water resistance - when water gets on the surface, the mechanical and insulating qualities are not lost, and are restored when dried;

high strength;

sufficient vapor permeability to create a comfortable microclimate;

excellent heat and sound insulation performance - due to the structure of the body of the plates does not conduct heat, and also reduces the intensity of sound waves of different frequencies;

· high class fire resistance - the material is difficult to ignite and does not support combustion, moreover, it does not emit smoke, toxic gases and substances;

long service life - during operation, the Greenboard not only does not lose its qualities, but also becomes stronger;

Environmental friendliness and safety for environment and people;

excellent adhesion to other building materials;

resistance to temperature extremes, as well as severe frosts and heat.

Due to the above properties, fibrolite material is used for additional heat and noise insulation of buildings, fixed formwork, frame construction, construction of noise barriers on highways, flat roof and even suspended ceilings- not every building material can boast of such a wide range of applications.
