DSP boards: sizes and prices, main characteristics and use cases. What is DSP

Today, the DSP board has gained popularity: the use of this material for flooring is very convenient. This is due to several reasons, the first of which is absolute environmental friendliness, the second is low cost. The board is based exclusively on natural raw materials. The connecting components are minerals, which do not emit poisons and microelements during operation that would be dangerous to human health. Among the ingredients of the canvas are wood shavings, water, Portland cement, as well as special additives. During the production process, the listed components are combined and undergo a pressing stage.

Application of DSP for flooring

Today, it is quite common to finish the floor area with DSP boards. This material is characterized by excellent thermal insulation properties In addition, it can be used in conditions characterized by high humidity. After laying the slabs it will be necessary to protect them with a primer or water-repellent mixture. The canvas will last for a long time, as it can withstand heavy loads. Depending on the traffic flow in the room, you can choose slabs with more or less impressive thickness.

Despite the fact that it has excellent performance, the use of flooring must be accompanied by compliance with all installation rules, only then will it be possible to preserve all the qualities of the material. With the help of such a slab, you can perfectly level the floor surface in a short time. The use of this material allows us to reduce the period of work. The floor will be strong and reliable, and construction costs will be significantly reduced.

Characteristics of DSP

The material contains 24% 8.5% liquid, as well as 65% cement, which ensures the durability and strength of the slab. In addition, among the ingredients there is 2.5% hydration impurities by type and Depending on the floor parameters, you can choose slabs that have dimensions equal to 3200 x 1250 mm, the thickness can vary between 10-40 mm. But, according to the standards, the slab can be manufactured with other parameters; deviations depend on the thickness.

Density and surface features

When considering the properties of a CBPB board, it is worth paying attention to the density, which should not exceed 1300 kg/m2, while the humidity can vary between 6-12%. When exposed to water for 24 hours, the canvas should not swell by more than 2%, and the slab can absorb moisture in a volume of approximately 16%. Tensile strength is 0.4 MPa.

The surface of the material should be rough, and the degree of roughness will be affected by grinding. If manufacturing is carried out in accordance with GOST 7016-82, then the roughness of the plates will be more than 320 microns, but the blade may not be subjected to grinding, then this indicator is within 80 microns.

Types of DSP

DSP board, the use of which today, as already mentioned, is becoming increasingly popular, is produced on modern equipment in several varieties. These are, for example, slabs whose thickness is only 4 mm. The resulting material does not require grinding, which, when done, causes an increase in cost. Slabs that have smooth embossing are becoming increasingly popular. They contain small elements, the size of which increases closer to the center of the canvas. Using this material you can get a floor that will look like natural stone. That is why the canvas does not require additional finishing after installation.

Advantages of DSP over other materials

If you have not yet decided what kind of floor covering will be laid: fiberboard or DSP board, the use of these materials for the floor, or rather, their qualitative advantages, is worth considering in more detail. Despite the fact that there are a great variety of slabs for repair work on the market of modern building materials, CBPB can be considered the leader. So, if we compare a sheet of DSP with a fiberboard sheet, then the first one is much stronger. In addition, cement particle board has the quality of frost resistance, which allows this material to be used as flooring in houses that are not used for the whole year, but only during the warm period.

If you need a fairly durable surface, then you should choose a cement-bonded particleboard: a cement-bonded particle board has just such qualities, they are due to the fact that the canvas is based on three layers, two of which (external) are made of fine chips, while the internal one consists of longer particles. This gives the material elasticity, high density and hardness. You should not be afraid that the slab will delaminate during use.

Preparatory work

The DSP board, the use of which is discussed in this article, involves the use of self-tapping screws when working with it. You can purchase canvases with a thickness in the range of 1-1.5 cm. As rough coating it is permissible to use wood or concrete screed. If there are logs on the floor, then the DSP can be installed on top of them. It is recommended to cut the material with fine-toothed teeth hacksaw blade. This will reduce the amount of dust generated, and the edges will be as neat as possible. Initially, the sheet just needs to be cut, laid on a flat surface, with the groove facing down. Next, you need to place your knee on the larger part of the canvas, and pull the smaller part towards you. In the required place, the slab should crack along the cut.

If during the repair work it is necessary to bypass the pipeline system, then grease should be applied to an element with the same diameter and leaned against it in the desired area of ​​the slab. This will mark the edges for cutting. Cutting work can be done using a “crown”. If you need to get a hole that is significant in size and has uneven edges, it is recommended to make a cut, observing the perimeter, and then carefully knock out the resulting element with a hammer.

Carrying out marking

Before installation, it is necessary to prepare sheets that will correspond to the parameters of the room. To do this, the canvases are laid out, and then markings are applied to their surface so that it is possible to carry out the correct cutting. After the sheets have been turned into blanks, they should be laid out again around the room and numbered - this will prevent mistakes from being made.

Features of laying DSP on the floor

Before laying the cement-bonded particle board on the floor, the cement-bonded particle board must be removed from the room to make it more convenient to work. Its installation is carried out using glue or self-tapping screws, depending on the features. If installation is intended to be done using glue, then it is preferable to prepare it using glue, which will eliminate the presence of lumps. However, the drill with the attachment must be set at low speed. It is unlikely that such a result can be achieved manually.

Ensuring clearances

The DSP board, reviews of which are usually only positive, can be laid on the floor after the craftsman manages to distribute the glue over the surface of the rough base. This must be done using a notched trowel. When laying the following sheets, it is necessary to provide a temperature gap, which will prevent deformation of the sheets when their sizes change. The resulting gaps can be filled with the same adhesive mass. After the floor of the room is completely covered, it is necessary to leave it until it dries. Only after this can you begin laying the decorative coating.

The technical characteristics of the DSP board are such that it can replace a concrete screed. And the advantage of the canvas is that it weighs much less than the solution, while it is easier to install. In addition, after completion of the work, the floor acquires heat-insulating and noise-reducing properties.

Sheet building materials are used in many types construction work, which are usually called “dry”. One of these materials is a DSP board. It is a durable material that can be used in construction frame houses and outbuildings, for indoor and outdoor finishing works.

What is a CBPB board?

Cement particle board (CSB) - foliage building material, which is made from high-quality cement (Portland cement) mixed with thin long wood chips (according to GOST 26816, chip thickness is 0.2-0.3 mm, length from 10 mm to 30 mm). Aluminum sulfate and liquid glass. When kneading, water is added (about 8% of the total mass). The resulting substance is molded into slabs and pressed.

DSP plate— sheet building material for interior and exterior work

Some manufacturers make CBPB boards from several layers. They separately mix compositions with smaller and larger chips. A mixture with large wood chips is used for the inner layers and gives greater strength. Outer layers are formed from a composition with smaller chips, which makes its surface smoother. The folded “pie” enters the press, resulting in the formation of monolithic slab DSP with improved characteristics.

It is also worth saying that there are polished and unpolished CBPB boards. Sanded ones can be used for interior or exterior finishing in those works that can be immediately followed by finishing work. There is also finishing slabs DSP, on one of the surfaces of which a finishing layer is formed in the form of stone or brickwork, decorative plaster etc.

Scope of application

DSPs are mainly used in dry installation technologies. They are good for the construction of frame houses, as they do not emit harmful substances, have high strength, low flammability, emit a small amount of smoke during a fire, and do not spread fire. Having a high mechanical strength, they increase the rigidity of frame structures. All this makes frame houses sheathed with DSP safer and more reliable.

Objects for using DSP

DSP sheets can be used in the construction of the following objects:

  • Frame residential buildings up to 3 floors inclusive.
  • Industrial, office buildings.
  • Hotel complexes.
  • Kindergartens, schools.
  • Medical institutions.
  • Gyms.
  • Warehouses, hangars.

Disadvantage: the CBPB slab has a significant mass (several times heavier), which increases the requirements for the foundation. The heavy weight also becomes a problem when climbing to the second floor - you need assistants and or lifting equipment (at least a winch). Another disadvantage of DSP is its low resistance to bending loads. This limits their scope of application - they are placed on the base, in places with low bending load, or must be mounted vertically.

Resistance to weathering and high humidity, fungi and bacterial infections allows the use of cement-bonded particle boards in the construction of outbuildings: sheds, garages, cellars.

For finishing external and internal works

Another area of ​​application for cement particle boards is leveling floors and walls. Compared to other materials, the DSP board has better sound insulation characteristics, is not susceptible to fungi, and tolerates climatic influences well. Therefore, they are often used to create ventilated facades.

For interior decoration DSP boards can be used for the following work:

  • Soundproof and fire-resistant partitions and walls.
  • Internal cladding of premises for any purpose (residential and non-residential, including those with high humidity).
  • Window sills.
  • Rough floor.
  • Ceilings.

The positive point is that there are cement bonded particle boards, sanded and unsanded. Polished ones have an absolutely smooth surface. When using them, you can only seal the seams and then paint, glue wallpaper, or use other finishing methods.

Characteristics and properties

DSP board is a relatively new material, not yet widely used in private construction. This is because not everyone can imagine how he behaves in long term. To understand whether it is good or not for your purposes, you need to know about all the properties.

Density and mass

Density of CBPB is 1100-1400 kg/m³. High density gives frame structures increased level of rigidity. If this material is used for interior finishing work, such walls have sufficient load-bearing capacity to support shelves, cabinets and other fairly heavy objects.

The material is quite dense and heavy. One sheet with a height of 2700 mm - depending on the thickness - weighs from 37 kg to 164 kg. This makes it inconvenient to cover the second floor and above. This can be considered a disadvantage.

Thermal and humidity expansion

Another important characteristic for construction is linear expansion with changes in humidity and temperature. For a CBPB board it is present, but it is small. When placing the plates one next to the other, it is recommended to leave a gap of 2-3 mm between them. When installing the second row (in height), the recommended gap is 8-10 mm.

  • Normal humidity for sale is 9% (±3%).
  • Low water absorption allows this type of material to be used for exterior finishing and for covering walls in rooms with high humidity. When in water for 24 hours, the limit for thickness increase is no more than 1.5%. That is, when wet they hardly change size.

What else is worth knowing: when immersed in water, the dimensions change slightly - 2% in thickness and 3% in length. If the material is made according to technology, then even after a long stay outdoors in the open air, it does not change for years.

Strength indicators and installation features

Cement particle boards do not tolerate bending deformations well, but have very high strength under longitudinal loads. That's why they are used for installation on vertical surfaces. Manufacturers do not recommend laying them on joists, but when laying them on a subfloor or rough screed the material behaves stably. Since the DSP board is not afraid of water, it can be laid on the floor in rooms with high humidity.

Modulus of elasticity:

  • in compression and bending 2500 MPa;
  • tensile strength - 3000 MPa;
  • in shear - 1200 MPa.

If the CBPB is mounted on a frame, sheathing is required in increments of at least 60 cm. During installation, fasteners are installed in increments of 20 cm. We install self-tapping screws not only along the perimeter, but also along the intermediate rivers of the sheathing. In this case, you can glue tiles onto the DSP board (a primer, after it dries - not adhesive composition you can lay tiles).

Fire hazard and frost resistance

The DSP board is a hard-to-burn material; fire does not spread across the surface; toxic or harmful gases are not released during combustion. Fire resistance limit (ability to contain fire) - 50 min. This means that the material will collapse after 50 minutes in the fire.

High frost resistance - the decrease in strength after 50 freezing/thawing cycles is no more than 10%, which allows the material to be used for building houses even in the Far North. The service life of this material outdoors is 50 years.

It is these properties that make DSP the more preferable material in. The structure turns out to be more reliable in terms of fire safety.

Soundproofing properties

The DSP board has good soundproofing characteristics and can be used for cladding external or internal walls:

  • reduction in air noise level for a slab with a thickness of 10 mm is about 30 dB, for a 12 mm thick slab - 31 dB;
  • reduction in the level of impact noise for slabs laid on a reinforced concrete floor - with a thickness of 20 mm is 16 dB, with a thickness of 24 mm - 17 dB;

When using additional intermediate layers, impact noise becomes quieter by another 9-10 dB. That is, frame walls covered with DSP boards block enough sound to keep the house quiet.

The best combination is a combination of cement bonded particle board and mineral wool. Mineral wool also serves as insulation, since, due to the homogeneity of the DSP, it has a low thermal resistance (it is not a thermal insulation material).

Performance characteristics

DSP boards are characterized by high vapor permeability - 0.03 - 0.23 mg/(m·h·Pa). This is about the same level as natural wood. At correct selection wall cladding, the humidity in the rooms will be regulated naturally.

In addition, the DSP board has high resistance to rotting. This happens due to the natural process of formation of calcium hydroxide, which is formed during the transformation of cement into concrete and alkalizes the material so that it becomes an unfavorable environment for the habitat of fungi, insects and putrefactive bacteria.

Dimensions and weight

When purchasing materials for construction and finishing work, such characteristics as the size and weight of the material are important. DSP sheets are available in two sizes: with a width of 1250 mm, the length can be 2700 or 3200 mm. In this case, the thickness of the DSP boards can be 8, 10, 12, 16, 20, 24, 36 mm.

It is clear that the thicker the slab, the greater its mass. Approximate weight values ​​are given in the table (different manufacturers may have deviations both in the direction of increasing and decreasing weight).

Weight cement particle boards depending on size and thickness

You may also need the following parameters:

  • area of ​​one sheet:
    • 1250*2700 - 3.375 m²;
    • 1250*3200 - 4.0 m²;
  • the weight of a cubic meter of CBPB is 1300-1400 kg.

The CBPB sheet is a homogeneous monolithic material without air inclusions, which explains the high thermal conductivity of the material. This must be taken into account when developing an insulation cake. The material adheres well to wood, polymers and metal, so it is convenient for construction work.

Mounting methods

The DSP board can be fastened with nails or self-tapping screws. When mounting on a frame, the slabs must be mounted strictly vertical.

Scope of application of cement bonded particle boards in private construction

To fasten cement bonded particle boards you can use:

  • Galvanized screw nails with a diameter of 2.5 mm. The length is selected depending on the thickness of the sheet and the entire cake. The pinched part of the nail must be at least twice the thickness of the slab, but not less than 10 nail diameters.
  • Screws and self-tapping screws with pre-drilled holes for the heads. The length is chosen according to the same principle.

When installing CBPB boards, it is necessary to strictly monitor the quantity and order of installation of fasteners: the material has a large mass, so fasteners must be installed at least as recommended. The distance between nails or screws depends on the thickness of the slab and is indicated in the table.

Each sheet of cement bonded particle board is fixed around the perimeter, departing a certain distance from the edge of the sheet. The frequency of installation along the long and short sides of the sheet is the same, but depends on the thickness of the material. In addition, there is also an intermediate mount - in the middle of the height. Here, the frequency of installing screws or nails is half as often as around the perimeter.

Processing and finishing methods

Despite the fact that cement particle board is much stronger, it is processed with the same tools: a router, a saw, a jigsaw. The difference is that you need to use stronger files.

For drilling, it is recommended to use a drill with a hard tip. You can use either a hand or electric drill. It is not recommended to grind this material, since this work removes top layer, which increases water absorption. But when docking, sometimes it becomes necessary to equalize the height. In this case you can use grinding machines any type. Recommended sandpaper grit is No. 16-25.

Please note that in order for the seams between the slabs not to crack, the seam must be at least 4 mm for the internal section, and at least 8 mm for the external section. The distance is large and can be closed with special slats (usually used when exterior decoration) or using elastic tape or sealant.

As a final finish, the DSP board can be painted or covered with plaster. For exterior finishing, the joints between the slabs are often simply painted over, leaving them unfinished. Another option is to use an aluminum profile trim that emphasizes the seams. You can also cover the seam with a strip.

For interior finishing, the seam is filled with sealant, which remains elastic after drying. After this you can plaster. The second option is to lay a special elastic cord, on top of which elastic plaster is again applied.

DSP plate, technical specifications which will be presented in the article, is used quite often today. It is distinguished by outstanding qualities that have made the material widespread in private and professional construction.

Characteristics of DSP slabs

Due to the fact that the described material has excellent characteristics, it is widely used in different areas construction. Cement particle board contains wood shavings, Portland cement, and special additives, the latter of which can provide excellent protective qualities. During the production process, all of the listed components are combined and then mixed until a homogeneous mass is obtained. Then the composition is pressed.

Products are manufactured in accordance with GOST, which strictly regulate the composition. Thus, the components should include 65% Portland cement, 24% wood shavings, 8.5% water, as well as 2.5% impurities. Density is ensured by the presence of Portland cement in the composition, the same component guarantees the durability of the material. The production of slabs is carried out on special equipment in a factory environment, as evidenced by a quality certificate, as well as a product passport. The boards contain natural wood, which ensures the environmental friendliness of the material. This indicates that the stove is completely harmless to humans.

Positive features of DSP

The DSP board, the technical characteristics of which must be found out before purchasing, has excellent quality, which allows the use of this material in professional construction. Technological processes The manufacture of plates is based on the mineralization and bonding of all components, so the appearance of a radioactive background, the release of steam, dirt or dust can be completely eliminated.

DSP boards are actively used in the construction of strong and warm housing. Quite often this material is compared with others. The slabs described are so durable that they win in this comparison. Their service life is much longer.
Additional advantages include excellent resistance to temperature changes and frost, which meets the requirements for modern building materials.

The DSP board, the technical characteristics of which are described in the article, has proven itself to be excellent. These products do an excellent job of repelling rodents, insects, as well as mold and mildew. The material does not contain phenol, asbestos, impurities or formaldehyde resins. These slabs can be used for all types of finishes. The surface of the slabs can be plastered, finished with plastic, painted, tiled, covered with various decorative materials, etc. It is easy to use this material, as it is easy to process. It contains a large amount of shavings, this makes the product look like natural wood, but these boards are highly durable. You can use DSP for the construction of partitions, which will have excellent sound insulation qualities. DSP walls will be able to provide sound absorption of up to 30 dB.

Strength characteristics of CBPB

DSPs whose technical characteristics differ from others alternative materials, have a high density. This is due to the fact that the chip pressing method is used during the production process. The inner layers of the product contain fibers that have a longer length. This guarantees the material excellent elasticity, smoothness, as well as high strength characteristics. The material has several layers, so it is able to combat moisture. The special technology used in production does not allow the product to delaminate. The plate will not break even if it is exposed to mechanical force according to the type of bend. The material copes well with high loads; during operation, it can be subject to mechanical impacts, which makes such slabs so widespread and popular in construction.

Cost of DSP

DSP is a slab, technical characteristics, the price of which should interest you if you plan to use this material in construction, may have different sizes. The most traditional dimensions are 1250x2700 mm. the cost of such a sheet will be 675 rubles. This cost can be called very affordable, which makes this material so popular among analogues. Despite the fact that the cost of the stove is quite low, its quality remains excellent.

Dimensions of DSP

The CBPB board, the technical characteristics of which must be indicated in the quality passport, must be examined by the consumer before purchase. It is important to take into account the size range of these products. The slab can have a width of 1250 mm or 1200 mm. The latter standard is considered modern. But despite this, slabs are still produced different sizes. The length can be equal to 2700 mm, while the thickness is equivalent to 8 mm. This product weighs 36 kg. If the thickness is increased to 10 mm, the weight will be 46 kg. A thickness of 12 mm increases the weight to 50 kg, and a thickness of 16 mm increases the weight to 74 kg. A plate thickness of 18 mm makes the mass equal to 81 kg.

With a slab length of 3200 mm, the thickness can be 8 mm, while the weight of the slab is 43 kg; with a thickness of 10 mm the weight will be 54 kg, while a thickness of 12 mm gives a weight of 65 kg.

The standard size is 1200 mm. A slab with a length of 2700 mm can have a thickness of 8 mm and a weight of 35 kg. A slab thickness of 10 mm gives a mass of 44 kg. Among other things, the buyer can purchase a slab that has been manufactured to specific dimensions. The length of the slab can be 3600 mm or 3000 mm. You should not look for products on sale whose edges have a semicircular shape, since such slabs are not produced. Also, products with thinner edges are not produced in a factory. Once the slab has been purchased, it will not need to be treated with an antiseptic, since the products are antiseptic at the factory.

Scope of application of DSP


The DSP board, the technical characteristics of which must be studied before making a purchase, is used today in housing construction. The products are able to provide internal protection from the cold. This material can be used when covering walls made of concrete. Products are used in low-rise construction, as well as during the construction of special-purpose buildings. DSP is excellent for rooms where conditions are characterized by high levels of humidity. After the slab is installed, its surface does not need to be treated. It will only be enough to coat the surface with a primer or a composition that has water-repellent characteristics. Buildings that use DSP can withstand severe operational loads.

Additional product applications

The DSP board, the technical characteristics of which can be found in this article, is also used for permanent formwork equipment, which makes it possible to achieve excellent results. At the same time, some positive features can be highlighted, among them: reducing the period of construction work, reducing the amount of construction costs, as well as ensuring reliability and strength future design. The DSP board, the technical characteristics whose use has made the products popular, is also used today in the manufacture of window sills. Moreover, the latter are not only durable, but also quite inexpensive compared to analogues. You should not assume that due to the insignificant cost of the DSP, the window sill will have a very unsightly and unpresentable appearance. Such products have excellent decorative qualities and resemble expensive window sills made of noble materials.

Cement particle board (CPB) is a material that is actively used in construction and repair work. Such plates are in demand in a huge number of areas. But even these fundamental structures are presented in a wide variety on the construction market. Before choosing a specific product, you need to familiarize yourself in advance with the features of these structures and the areas of their use.

Production Features

Cement particle board is manufactured using special technologies. The process of creating a DSP includes the following steps:

  • The solution is based on water, which is poured into a special mixing container. Aluminum, salts and liquid glass are also added to the container;
  • for mineralization to take place, shavings elements are added to the mixture;
  • at the next stage, cement is added;
  • to obtain a DSP block, the solution is poured into a special mold;

  • a certain thickness is given to the substance using a press;
  • after pressing the product passes heat treatment, the implementation of which takes into account the characteristics of the components of raw materials;
  • In order for the substance to harden, it is placed in special chambers. There, at a temperature of 80 C, the components are fixed;
  • After hardening, the canvas is cut into sheets. Their sizes are determined by GOST.

Products are manufactured only in special factories, where strict control over the implementation of each stage is carried out. Make it yourself high-quality panel DSP is impossible.

Characteristics

Cement-bonded products have a number of fixed technical characteristics that explain many of their properties:

  • a quarter of the composition is made of wood chips, a little more than 8% is water, the main component is Portland cement and additional impurities account for 2 and a half percent;
  • material thickness varies from 8 to 12 mm;
  • The width of the slab is 120 or 125 cm;
  • length – from 2.6 to 3.2 m. To order, you can choose a model up to 3.6 m long;
  • weight of one square meter DSP having a thickness of 8 mm reaches 10 kg.

The material has a high density, which reaches 1300 kg/m3. During the process of moisture absorption, the density can increase by 2 percent. The limit of water absorption capacity usually does not exceed 16%.

The roughness of a CBPB board is the relief of each sheet. It depends on the grinding characteristics. Unsanded boards have a reading of 320 microns, while material that has been sanded has a reading of 80 microns.

The sheets have a fire resistance class of G1, which means that the material has low flammability. The thermal conductivity index is 0.26 W.

All of the listed characteristics allow you to select the required number and parameters of the building material.

There are also various types materials for slabs and cast products from CBPB:

  • Xylolite– high-strength material with good thermal insulation. Such slabs are often used for flooring. Products are presented in a wide range of colors.
  • Fibrolite is a raw material consisting of long fibers. It has high thermal insulation properties and soft texture. Biological factors do not have a strong impact on this type of DSP.
  • Fine-chip materials include wood concrete, which is used in various fields.

Pros and cons

Like any building material, DSP has a number of advantages and disadvantages. The advantages of such plates include:

  • The material is very resistant to moisture and temperature changes. The slabs can withstand up to 50 frost cycles. This characteristic significantly affects the service life of the slabs.
  • The raw materials used to create such partitions are absolutely safe for human health. DSP does not release harmful toxins and does not cause allergic reactions.
  • Cement bonded particle board is perfect for various transformations. With it you can use any finishing methods and change the surface of the product at your own request.
  • Wide range. In modern construction stores You can find a rich variety of products.
  • The affordable price is important advantage. Since the material is often used when building a home from scratch, purchasing large quantities of material will not negatively impact your budget.

  • Cement-bonded products are easy to use. On such a surface it is convenient to carry out various repair work using a drill, hammer drill or knife.
  • The fixed size of the products significantly facilitates the installation process.
  • The material is resistant to rotting processes.
  • When cement bonded particle board is used to screed floors, it contributes to significant savings means, compared, for example, with self-leveling compounds or cement-sand leveling option.

The negative properties of DSP include:

  • Products can reach a large mass, which significantly complicates their use in high rooms. The high weight is due to the high density of the material.
  • The material is not plastic. If you try to bend such a slab, you can break it. The risk of breakdown during construction work explains the need to purchase material in reserve.

Based on the presented data, it is clear that DSP has significantly more advantages than disadvantages. The disadvantages of such products are easily compensated by their advantages.

Scope of application

Cement particle boards are used in various construction and finishing fields. The most common applications are:

  • External . It implies the suitability of slabs for finishing the façade of residential premises and the use of slabs as a basis for fencing. Work on the implementation of permanent formwork is also possible. DSP sheets can be used both in private and industrial areas. These slabs are used to construct protective structures for beds in private homes, and parts for industrial enterprises.
  • Cement particle board is indispensable in construction frame house. In this case, it acts as an excellent insulation. The products are used to create heated floors. They are also often used for walls, subsequently creating interesting decor on the slabs.
  • The material's resistance to moisture allows it to be used as ceiling covering in saunas and other types of premises where the humidity level is high.

  • Often such sheets are used to create partitions in rooms. In order for the slabs to serve longer as a separator, they are coated with a special paint that performs a protective function.
  • The most the best varieties Cement particle boards are used to create furniture.
  • The material is used to create window sills. It becomes a more affordable alternative to wooden structures, and at the same time lasts no less long.
  • It is permissible to make a special base for roofing in private houses from dense slabs.

  • A very common area of ​​application for slabs is restoration. The material is often used to give old buildings a better look. In addition, due to their relatively low price, the products are quite suitable for large-scale work.
  • Thin slabs are often used to decorate such attributes of private homes as fireplaces and chimneys.
  • Cement particle boards are sometimes used as an alternative to cement when screeding floors.

DSPs are suitable for various types of work. The following processing options for cement-bonded particle board products can be carried out:

Omsk company "Stropan" is engaged in the production of elastic cement bonded particle boards of various thicknesses. The company is also distinguished by the creation of sheets with increased sound and thermal insulation.

Knowing the list of leading companies, you can easily choose slabs that you will not be disappointed with later.

Depending on how exactly you decide to use DSP for your home, you should listen to various recommendations for correct installation these slabs.

The most common option is to insulate walls or floors using cement bonded particle boards. To carry out this procedure, it is necessary to prepare the surface of the walls in advance by providing it with metal and wood lathing. It is necessary to have special cells having a fixed size of 500*500 mm.

During installation, leave 1 centimeter space between the plates. It is covered with a special cover, for which you can use finished products from the same material or create them yourself from residual raw materials.

To secure the canvas, you must use nails, screws and self-tapping screws. Fastening can be done in alternative ways - using mastic or a special adhesive solution.

For insulation frame structure slabs must be installed from the outside and inner sides walls at the same time. If you want to insulate a utility room, then it is permissible to leave a small space between the base of the wall and the DSP sheet.

In private homes, many people install cement-bonded particle boards on wooden floors to make them warmer. To correctly carry out this process, you must follow a special algorithm:

  • To avoid creaking floors in the future, the base is adjusted and secured with self-tapping screws. When adjusting the base coating, it is imperative to remove rotten boards and replace them with new ones. If there are cracks or cracks of an insignificant nature in the surface, they must be treated with putty.
  • Rooms are measured taking into account the location of the long side of the canvases across the boards.
  • It is necessary to design on paper a diagram for laying CBPB.
  • Using a grinder, you need to cut the sheets to the required parameters, if necessary.
  • The slabs are installed in the direction from corner to corner. In this case, it is best to fix the products using zinc screws.
  • The seams between laid sheets should be primed. Only after completing all stages can you carry out external finishing floor covering.

A special process is the use of DSP for floor screed. To correctly carry out the dry screed procedure, it is necessary to lay the sheets on a special filler with granules and metal profiles made of plasterboard or wooden blocks. Self-tapping screws for fastening cement-bonded particle boards must be suitable for the cross-section of the beams and the material from which they are constructed. This leveling method is used only if the difference in level differences is more than 6 cm; raising the level with the help of canvases is permissible on average to a height of 7 to 10 cm.

The first enterprises for the production of cement-bonded particle boards (CPB) were opened in the USSR in the late eighties of the last century, and many of them are still operating today. Cement and chip boards are not as popular as plywood, plasterboard or OSB, but they are a versatile material with a wide range of applications and high technical and performance characteristics. Members of the FORUMHOUSE portal know about all the advantages of DSPs and actively use them, including on the facades of their houses.

Cement particle board - raw material base, manufacturing method, technical characteristics

One of the main advantages of these boards is their natural composition - they do not contain formaldehyde or other aggressive chemicals released in environment during operation. Products different industries The composition of mineral additives may differ, but the quantitative proportion of each group of substances used is unchanged:

  • Binder (Portland cement m500, GOST 10178-85) – 65%;
  • Wood shavings – 24 %;
  • Water – 8.5%;
  • Hydration (mineralizing) additives – 2.5%.

DSP is composite material made from a mixture of cement and smooth, thin wood shavings coniferous species. Since wood contains sugars and other substances that negatively affect cement and make it difficult to form a monolithic structure, mineralizing additives are used to neutralize them. This can be calcium chloride, aluminum sulfate, aluminum sulfate, aluminum chloride, sodium silicates and others. The chips are treated with reagents, mixed with cement until a homogeneous mass is formed, and then sent for molding. To increase strength and obtain a smooth and uniform surface, slabs are formed from several layers, which differ in both the size of the chips and their location. Most often there are three layers - the middle one, made of coarser and larger chips, the outer ones, made of smaller ones. Some industries form a particle-cement carpet of four layers, but the principle is the same - large fractions inside. The formed slabs are pressed under a pressure of 1.8-2.0 MPa, after which they are subjected to heat treatment in a hardening chamber (8 hours at 50-80⁰C, humidity 50-60%). The parameters of the finished slabs must comply with GOST 26816-86, there is also a European standard - EN 634-2.

The slabs have a lot of physical and technical characteristics that will tell little to the average consumer, who is mostly interested in
does the DSP stove burn, so let’s look at the main ones:

According to the regulations, slabs can be either 1250 mm or 1200 mm wide. The first option is outdated, although many enterprises, especially the “mastodons” of the industry, still produce slabs of this width. Length: two main sizes are common - either 2700 mm or 3200, but there are also 3000 mm options, and the required parameters can be made to order. With a lot of advantages, the slabs have significant drawback– due to the raw material base, they turn out to be quite heavy. The thinnest slab, 8x1250x3200 mm, will weigh about 36 kg, and a 40 mm thick slab with the same dimensions will already weigh 185 kg. Therefore, when working with slabs, an assistant is usually required, equipment is required to unload large quantities, and the limitation for use on the facade is a height of more than three floors. But this material is used in almost all construction fields, depending on the thickness:

  • Internal wall cladding – 8-12 mm;
  • Interior partitions– 8-20 mm;
  • Roofing systems, facade cladding – 10-16 mm;
  • Subfloor (ceilings, floating screed) – 16-26 mm;
  • Formwork – 14-26 mm;
  • Enclosing structures during the construction of frame houses - 10-40 mm.

DSP board: application for external work

One of the options for using DSP is a facing screen in ventilated facade systems. The result is a smooth surface, resistant to external influences, completely ready for use. finishing. Since when installing slabs an expansion joint is required (6-8 mm, minimum 4 mm), most often such cladding is combined with a half-timbered finish. It is also possible to paint the canvas with facade paints, like one of our users.

I have a foam plastic house, DSP outside and inside. The outside is painted with façade water-based emulsion on sheets, it holds up perfectly, the inside is wallpapered using DSP - everything is great. It’s really easy to hang it with two people, sawing the slab with a grinder and a stone saw.

The technology for installing DSP on the facade is standard: lathing from wooden beam or metal guides, with a pitch between posts of 600-625 mm (depending on the width of the slab). There must be a ventilation gap of at least 40 mm between the insulation and the DSP. The plates are attached to the sheathing with self-tapping screws; it is recommended to use galvanized or anodized ones, since black ones, even if the caps are puttied, can cause damage over time. rust spots and through several layers of paint. Holes are pre-drilled in the slabs for self-tapping screws; if the screws are ordinary, countersinking is performed - a chamfer is selected in the upper part of the hole so that the self-tapping screw is recessed into the slab. When using self-tapping screws, the installation process is simplified.

Since DSP is quite heavy and to some extent brittle material, it is necessary to follow certain standard fastening rules given by a member of our portal.

For DSP as a facade material, you need to remember linear changes in geometry when humidity and temperature change. They exist, like any slab material. To resolve the issue with proper use and lack of further negative consequences, installation technology must be followed.

  • The fastener spacing along the edges of the slab is 300 mm;
  • Distance from the edge – 16 mm;
  • The fastener pitch in the middle of the slab is 400 mm;
  • Fastening the corners (against chipping) - at a distance of 40 mm on the long and short sides.

Expansion joints can be left open, covered with flashings or decorative overlays(false timber) or sealed with special compounds (when finishing with plasters). If sealing of seams is not planned, and the facing cake does not include insulation, before installing the slabs, the racks are protected from moisture (special impregnations or insulating tapes).

Portal member Andrey Pavlovets used DSP with imitation half-timbering for building cladding country house and baths and am completely satisfied with my choice.

The house and the bathhouse have been standing for about 12 years now - everything is sheathed with DSP, and the house had to be sheathed alone, due to the lack of helpers. To make it easier to work, I sawed the slab into 1200x1200 mm squares, stacking the sheets, then drilled and inserted the fasteners. Sheathed by old clapboard, so small cracks for ventilation remained. And the pie is as follows: outer layer - DSP - 10 mm, lining - 20 mm, glassine, lathing - 25 mm, mineral wool– 100 mm, film (vapor barrier), air – 50 mm, lathing – 25 mm, plasterboard, finishing (wallpaper).

After installation, the walls were painted with two layers of water-based paint facade paint, with a roller, the seams are covered with planed overlays edged boards, painted in dark light. The layout of the overlays was chosen taking into account the seams of the cladding. Although no primer was used, the paint has not peeled off over the years, and the house has not been damaged original appearance. However, if you follow the technology, preparation (priming) is a mandatory stage of work, and you should not neglect its implementation.

Cement-bonded particle board is also used for cladding frames and as enclosing structures.
