CPS stove what. DSP board: characteristics, application, board sizes, reviews
IN modern construction And finishing works The term DSP is often used. The abbreviation stands for cement bonded particle board, and it is one of the popular and high-quality building materials.
Thanks to innovative technology manufacturing, CBPB boards have unique characteristics that are noticeably higher than those of wood-fiber analogues, plasterboard and plywood. Let's look at the key benefits of this building material.
Main technical characteristics
Cement-bonded particle boards are made from crushed wood chips and cement, adding substances to the composition that completely eliminate the conflict of materials. The raw materials are laid one by one, forming a multi-layer sheet with special properties, which is formed by a hydraulic press.
As a result, DSPs have the following characteristics:
Sound insulation indicators - up to 45 dB.
Change standard sizes with prolonged exposure to a humid environment - no more than 0.3-2%.
Bending and tensile strength - 2,500-3,000 MPa, respectively.
Fire safety - class G1 (low-flammable materials).
The average service life is up to 50 years.
It is worth noting that DSP boards are resistant to temperature changes, are easy to process and are not susceptible to mold formation. Disadvantages include dependence on humidity environment: if the material is in contact with water for a long time, the service life is reduced to 15 years.
Is it burning or not?
The combustibility of a material is one of the key issues of interest to builders and finishers. Considering that the composition includes wood, cement particle boards can catch fire, however, this requires prolonged exposure to high temperatures.
When you are in a completely blazing house, the DSP needs contact the fire for at least an hour before it ignites. In addition, the material does not contain active chemical components, so even in the event of a fire, there is no risk of poisoning from combustion products.
Composition of the CBPB board
When producing cement-bonded particle boards, manufacturers are guided by GOST standards that are used for this type of building materials. In particular, the following ratio of components included in the finished product is used:
Portland cement - no less than 58%.
Additional impurities - 2.5%.
Crushed wood shavings - at least 30%.
It should be clarified that the percentage of raw materials used must be indicated on the packaging. Here are the data recommended by GOST, which may differ slightly for the products of some manufacturers. However, when choosing a material, you need to focus on the given values: this is the key to the quality and strength of the CBPB boards.
Application
Main area of use of this material- this increases the thermal insulation properties and sound insulation of premises. Therefore, the material is often used in private residential buildings and in the construction of commercial and industrial facilities.
Cement bonded particle boards are optimally suited for interior and exterior finishing walls, preparing the floor for finishing. In addition, the material is often used for arranging interior partitions.
Regardless of the scope of application, DSPs are guaranteed to withstand the service life declared by the manufacturer, which is about 50 years!
Standard sizes
As already mentioned, CBPB boards are manufactured in strict accordance with GOST standards, and accordingly have strictly defined external parameters. If we talk about standards, the following sizes apply here:
Sheet length - 2,700/3,200/3,600 mm.
Width - 1,200-1,250 mm.
Thickness - 8-36 mm.
It is necessary to clarify that this data is relevant only for products from domestic manufacturers. The European construction market has different standards.
Sheet weight
In the table above, the data is shown in a separate column. The weight of the sheet directly depends on two fundamental factors: thickness and area of the product. At the same time, the length and width of the sheet are usually standard; only the thickness changes, which largely determines the performance characteristics and scope of application. Let's look at weight change standard sheet(3,200*1,250 mm) depending on thickness. It looks like this:
Thickness 10 mm - weight 54 kg.
12 mm - 64.8 kg.
16 mm - 80 kg.
20 mm - 108 kg.
The weight of the densest sheets can reach up to 194 kg, however, such material is very inconvenient for independent work. For cladding walls and arranging interior partitions, sheets are usually used, thickness 16-20 mm.
How to cut this material
It’s worth clarifying right away that it is better to cut cement particle boards in production workshops: the work is very dusty and requires special tool for an even cut. At home, you can use the following devices:
The working surface of the tool must be made of carbide materials, rotation speed circular saws: no more than 200 rpm.
To minimize room contamination and reduce the amount of dust, it is recommended to spray the surface of the material being cut with water and prepare a vacuum cleaner to suck up fine particles.
List of verified manufacturers
On the Russian market, there are several proven companies producing high-quality products that meet GOST standards. When choosing a DSP, you can pay attention to the following manufacturers:
JSC "TAMAK". The company is located in the Tambov region, producing cement particle boards according to domestic and European standards(EN 634-2). The products are solid monolithic sheets without the slightest defect.
LLC "TsSP-Svir". The company operates in the Leningrad region, filling the market with quality products. Characteristics finished sheets: polished or calibrated surface of light gray color. The production uses German equipment, which ensures the production of CBPB boards according to Russian and European standards.
JSC "MIT". The company's production line is located in the Kostroma region. The finished sheets have a clear geometry, comply with Russian quality standards, and are sold in an affordable price segment.
LLC "Stropan". The company operates in the Omsk region. The main characteristics of the finished sheets look like this: thickness from 10 to 36 mm while maintaining standard dimensions, elasticity of the material - 3,000 MPa, excellent thermal conductivity and sound insulation.
LLC "ZSK". The company is located in the city of Sterlitamak, Republic of Bashkortostan. The manufactured products have standard sizes corresponding to GOST, and are resistant to aggressive environmental influences and temperature changes.
It is important to clarify that everything Russian companies for the production of cement particle boards, they work on equipment from Western manufacturers. This helps to produce high-quality products at reasonable prices.
Useful to know during installation
It must be remembered that you need to work with cement particle boards very carefully: the large area of the sheet makes it fragile, so installation is carried out by at least two people.
In addition, CBPB boards are not laid closely; expansion joints must remain. The material contains wood, which tends to expand under the influence of a humid environment. Given this feature, it is not recommended to fill joints with putty. It is better to use a sealant that will not interfere with the expansion of the DSP boards.
Construction modern buildings requires more and more advanced, universal, high-quality and inexpensive materials. One of the latest developments in this direction is CBPB, which can roughly be called an improved version of particle boards.
Cement particle board as a building material
Cement particle board, which appeared on the building materials market relatively recently, has already been appreciated by many developers. Thanks to excellent operational characteristics, with its help, dry installation of structures is carried out in buildings for various purposes.
DSPs are manufactured using the pressing method. Hardwood shavings (its share is 24%) are mineralized under the influence of special hydration additives (2.5%), after which Portland cement (65%) and water (8.5%) are added to it. As a result, a monolithic smooth slab emerges from the press, consisting of several layers with large fractions on the inside and small ones on the outside.
Types and characteristics
There are 3 types of DSP:
- fiberboard– heat-insulating material based on long-fiber shavings (“wood wool”). Soft, easy to process, resistant to biological factors;
- wood concrete– made from sawdust and small shavings. Has wide scope applications (thermal insulation, finishing, material for wall partitions, etc.);
- xylolite(slab and cast). It has high strength, thermal insulation qualities and a wide range of color solutions, used as flooring.
Due to their water absorption, the slabs increase in size, so when installing, a gap is required between them
Pros and cons of slabs
The high popularity of DSPs is explained by their many advantages:
- if the installation was carried out in accordance with the technology requirements, The service life of the slabs can reach 50 years. Research results have shown that the material does not lose its beneficial properties even after repeated cycles of freezing and thawing. The boards also showed high resistance to moisture, fire and biological factors;
- multilayer structure provides high strength characteristics of the DSP for tension and compression, which allow you to strengthen frame structures using slabs;
- slabs are often used as insulation, which is explained by their good heat and sound insulation qualities;
- material processing is not special labor. He easy to drill and cut, its flat surface is excellent for applying putty, plaster and adhesive compositions, thanks to which the slabs are successfully used in the decoration of premises;
- exact dimensions of the slabs significantly speed up the installation process;
- the front side of the DSP can have not only a flat, but also a corrugated surface. This ensures a variety of room design;
- ecological cleanliness;
- relatively low cost.
There are significantly fewer disadvantages of cement-bonded particle boards:
- heavy material weight(about 14.5 kg per square meter), which significantly complicates the installation process. This is explained by the high density of CBPB (up to 1400 kg per cubic meter);
- low strength indicators bending, which sometimes leads to breakage of the slabs.
Scope of application
These slabs are used in large and private construction. They are used to build houses, utility rooms, use them indoors and outdoors, and even make furniture. The thinnest slabs (from 10 to 16 mm thick) are used for cladding the internal and external walls of buildings for various purposes. For fastening, it is necessary to first make a sheathing made of wood or metal profile. In addition to aesthetic this design can also serve thermal insulation purposes. In this case, the space between the DSP and the wall is filled with insulation. This method often used to modernize old buildings. Its advantages are simplicity and relative low cost. The permissible gap between the plates is up to 1 cm. The joints are sealed and overlays are attached over them.
The same DSP (up to 16 mm) also used for making internal partitions
. Due to their high moisture resistance characteristics, they are often installed in bathrooms and other similar rooms. The slabs are pre-primed, the surface and edges are treated with water-repellent materials. They are also used to produce balcony railings, cladding for fire-resistant doors, etc.
From the best varieties DSP can even make furniture
From DSP from 12 to 24 mm perform permanent formwork for foundations V low-rise construction. The high strength of the slabs prevents their deformation when pouring the mortar. Another advantage of the design is its simplicity. If the DSP is painted or covered with a waterproof material, they can serve as vertical waterproofing.
Window sills made of cement-fiber boards fit perfectly into any interior. They have all the advantages of wood products, but at the same time they are much cheaper. The thickness of the slabs used for the production of window sill boards is 24-36 mm. They are not subject to deformation, durable, monolithic and affordable.
When arranging floors Cement particle boards successfully replace chipboards. If a floor made of CBPB is laid on logs, then the distance between them should be within 60 cm, and their cross-section should be at least 5x8 cm. CBPB with a thickness of 16 to 36 mm can act as a base, underlying, leveling or finishing layer with the front finishing. In some cases they are used instead cement screed, as well as during the construction of a prefabricated floor on bulk soils (CPB floor slabs with a thickness of 24-36 mm).
A base for soft roof
. For this work, 16-24 mm slabs are used.
Installation methods
DSPs can be mounted in various ways depending on the purposes for which they are used. When finishing or insulating buildings, they are attached to the sheathing, made of metal profiles or wooden blocks, with self-tapping bolts or nails. The installation of permanent formwork also involves erection of the frame (given the large weight of the slabs, it, like the sheathing when finishing the walls, must be strong enough). In addition, the slabs can be laid on joists (when installing the floor) or rafters (under roof covering). At interior decoration them also can be attached to the wall with mortar or mastic.
Release form and cost
DSP is sold in sheets packaged in bundles. Panel thickness varies from 8 to 36 mm. Dimensions can be (in mm): 2700x1250, 3200x1200, 3200x1250 and 3600x1200. The number of sheets in a pack depends on the dimensions.
The cost is set per square meter or per sheet. In the first case, it depends only on the thickness, in the second - on all panel parameters. The sizes of CBPB slabs for walls differ from those used for floors, but the price is approximately the same. Price square meter 8 mm DSP from different sellers starts from 150-250 rubles. The most massive slab (36 mm) will cost about 4-5 times more.
According to their own beneficial properties(except, perhaps, only for the weight) DSP is in no way inferior to its wooden counterparts and even surpasses them. And the versatility of the material, combined with an affordable price, makes it practically perfect choice for construction and finishing works.
The construction of a house from fiber board in a month is described in this video:
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 installation, the slabs will need to be protected 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 plate you can short terms create a perfect leveling of the floor surface. 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 are 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 with 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 the market of modern building materials offers a great variety of slabs for repair work, DSP can be considered a leader. So, if we compare a sheet of CBPB with a sheet of fiberboard, then the first one is much stronger. In addition, cement particle board has the quality of frost resistance, which makes it possible to use this material as a floor covering 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. 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 flat surface, facing the groove 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 repair work it is necessary to bypass the pipeline system, then it is necessary to apply grease to an element with the same diameter and lean it against in the right area slabs 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.
Specifications DSP slabs are such that they can replace 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.
Among the slab and sheet materials used for finishing and constructing partitions and various design elements, one cannot ignore cement-bonded particle board or cement-bonded particleboard. Of course, in terms of popularity it is inferior to drywall, but, as practice shows, it is also suitable modern world there is a place. Most often, the DSP board is used by builders as formwork. It is smooth, with good strength, plus - with its help, it is much faster to assemble formwork than from boards.
Many may doubt that the use of DSP is advisable for the construction of formwork. After all, it can be replaced, for example, by metal or plywood, which are also used. This is probably true, but a slab with a thickness of 24-26 mm can withstand quite serious loads. Moreover, if you install permanent formwork using cement-bonded bonding material, then, in fact, you will get a ready-made finished foundation or other structural element buildings. And this is a big plus in many situations.
In addition, it is necessary to take into account the conditions under which the room being finished will be used. For example, if this is a gym, then there can be no talk of any drywall. He just can't withstand the ball's impact. And the DSP boards will hold up. They can be used for strapping and sheathing frame houses. Today you cannot find better material for this value. Another advantage is the ability not only to paint the cement-bonded particle material, but also to use it as finishing. Fortunately, manufacturers today offer huge assortment with registration under different materials, as shown in the photo above.
DSP production technology
From the name itself it becomes clear that the main components of this material are cement (65%) and wood shavings (24%). All this is mixed with water (8.5%), and various additives are added to the resulting mixture to improve the technical characteristics of the slab (2.5%).
In the process of producing CBPB, two types of particle boards are used. They differ in size: small and medium. The slab itself has a three-layer structure, so medium-sized chips are poured into the second layer, and small chips into the first and third. Myself production process takes place in the following sequence.
- The shavings are mixed with hydration additives.
- Cement grade M500 is added to the resulting mixture.
- Water is pouring in.
- The solution is thoroughly mixed until a homogeneous mass is obtained.
- The first layer of fine chips is poured into the mold.
- The second layer with medium-sized shavings.
- And the third layer.
- Pressing is in progress.
- After which the semi-finished material is heated to +90C for eight hours.
- Then it is dried under natural conditions for 13-15 days.
- After which, depending on the batch, it is either polished or simply stored.
Specifications
The fact that this is a durable material is clear, because it contains cement component. But it is also moisture resistant due to the use of hydration components. Plus, DSP boards have excellent bearing capacity, which cannot be said about gypsum board or plywood. But a lot will depend on the parameters of the stove.
As for the width, it is standard - 1.2 m. But the thickness and length are dimensions that vary over a fairly wide range. As for the length, the manufacturer can cut it to any size if the order batch is large. But there are also standard values: 2.7; 3.0; 3.2 and 3.6 m.
As for thickness, there is a fairly decent range here too: from 8 to 40 mm. Accordingly, the weight of the product will increase with increasing thickness. For example, a slab 2.7 m long and 8 mm thick weighs 35 kg. With a thickness of 40 mm, the weight will increase to 176 kg.
With a DSP length of 3.2 m and a thickness of 8 mm, its weight will be 41 kg. With the same length and thickness of 24 mm, the weight will be 124 kg.
There are no rounded edges or chamfers in the design of the DSP boards. The edges are straight and cleanly cut, so there shouldn't be any problems with joining panels and fitting. They do not need to be treated with antiseptic compounds before finishing, because during the manufacturing process an antiseptic is added to the raw solution.
Other technical characteristics according to GOST:
- Withstands large subzero temperatures. In this case, the defrosting process can occur up to 50 times. After which the strength of the slabs decreases by only 10%.
- The error on the outer plane is 0.8 mm.
- The difference in the lengths of the diagonals can be 0.2%. This is practically no more than 5 mm for a length of 2.7 m.
- Thickness error (permissible) is no more than 0.8 mm. This is for unsanded material, for sanded material 0.3 mm.
- Water absorption is 16%, while per day at high humidity the slab should not increase in size by more than 2%.
- Withstand tensile loads - 0.4 MPa, bending loads 9-12 MPa, depending on the thickness of the product. The thicker it is, the less it can withstand bending loads.
Manufacturers today offer two types of cement-bonded bonding material, which differ from each other quality characteristics. These are TsSP-1 and TsSP-2. The first one is better.
There is an opinion that slabs of this type are inferior to plasterboard in many respects. You should not compare these two materials, they have different purposes and different areas applications. The examples described above confirm this. Of course, DSP has its drawbacks, which we’ll talk about.
- Compared to plasterboard, cement-bonded particle boards cost almost twice as much. But gypsum board cannot be used for exterior decoration, and even sheathed with it frame house It's better not worth it.
- The weight of each slab can be terrifying, especially those with a thickness of more than 16 mm. You won't be able to work with them alone. Under them you will have to build a strong and reliable frame. And the foundation will have to be strengthened if they are used to cover a frame structure.
- In addition, the cement component gives the material increased strength, so it is difficult to process. Therefore, pruning should be done with a grinder or manual circular saw, but it’s not easy to use cutting tool, but diamond.
- The frame has already been mentioned, but it must be added that profiles for drywall are not suitable here, especially if we're talking about O exterior decoration DSP boards. A standard steel profile is required here.
- When cutting slabs, it releases large number dust, so this operation should only be performed outdoors.
The construction industry is one of the most actively developing today. From time to time, new technological solutions appear on the building materials market. One of these innovations is DSP boards, the sizes and prices of which have greatly pleased both specialists in this field and ordinary consumers. Today, together with HouseChief experts, we will try to figure out what is unique about this building material, what are its positive qualities, and does it have any disadvantages?

What is DSP
The uniqueness of the sheet building material, which received the short name CSP (cement particle board), lies in the fact that it managed to combine seemingly incompatible components - Portland cement and crushed wood shavings. This became possible due to the introduction of special hydration additives that neutralize the harmful effects of the components included in the slabs on each other. Modern manufacturers learned to make slabs without the use of phenol and formaldehyde, which are harmful to human health.
Technically, the process of making plates is as follows:
- The raw material mass is formed in a special drum, into which wood chips, mineral components, Portland cement, and water are sequentially added.
- The formation of the slab occurs layer by layer, with finely ground chips located outside, and larger ones inside the product, thereby ensuring its strength. The smoothness of the front layer is achieved due to fine chips.
- Moving on conveyor line, the workpiece falls on hydraulic press, where under high pressure it is molded.
The ideal smooth surface allows you to evenly or wall. If you cover the house with panels and paint them in one of the pastel colors, you will get classic facade in , where main role Decorative strips covering the joining seams between the panels will play a role.
Water-repellent properties have made products based on shavings and indispensable for finishing wet areas.
Technical characteristics, application of CBPB boards
- The density of the products should be from 1100 to 1400 kg/m³ under normal humidity conditions.
- Water absorption should not exceed 16%.
- Changes in linear dimensions are allowed when high humidity(6–12%) in width by no more than 2%, in length - by 0.3%.
- The bending strength should be: 12 MPa for panels with a thickness of 10, 12 and 16 mm, 10 MPa for slabs with a thickness of 24 mm and 9 MPa for slabs with a thickness of 36 mm.
- The strength of the slab under perpendicularly applied tensile loads must be at least 0.4 MPa.
- Sound insulation properties are 45 dB.
- Thermal conductivity – 0.26 W/m×°C.
- According to GOST 7016-82, the value of the roughness level after factory grinding should not exceed 80 microns. For untreated boards this figure is 320 microns.
- The material belongs to the group of low-flammable products (G1).
- For dry premises, the service life is 50 years or more.
