In private housing construction, the choice between wood and stone is the most fundamental question before starting work. Both materials have their pros and cons. What happens if you combine beneficial features cement and wood in one material? The result will be CSP (cement particle board). This is what we will talk about in this article: we will try to understand what types there are and how easier it is to choose a DSP.
Features of cement bonded particle boards
The material is a symbiosis of wood and cement. Unlike other particle boards, it does not contain any synthetic resins, the main binding component is cement. Cement with strength grade M500 is used. Wood chips are sorted into fractions and stabilized. Also added to the product chemicals(aluminum sulfate, sodium silicate), which prevent the process of rotting wood ingredients and eliminate Negative influence chip component for cement. All ingredients are mixed with the addition of water in an industrial mixer. The products are then formed and pressed dry using compressed air.
Compared to other wood-based boards, DSP has a number of features.
- Environmental friendliness- the material does not contain any synthetic resins that are found in chipboard, OSB or fiberboard. Therefore, those who are concerned about the formaldehyde content in composite products should pay attention to DSP.
- High stability- cement- particle boards have high wear resistance and moisture resistance. They absorb moisture less than other wood-composite products, while maintaining their overall shape - they do not swell.
- Strength allows the use of DSP as a structural material, cement slabs superior to other composite analogues, such as fiberboard and OSB (oriented strand board).
Frame house with walls made of fiberboard
Oriented strand board is a composite material consisting of large pieces of wood chips that are arranged in layers and pressed into monolithic slabs. The binding element is formaldehyde resins. Products are sensitive to moisture and are easily deformed under its influence. can be an excellent alternative to OSB during construction frame houses.
- Fire safety- another plus of the DSP is that the boards do not contain resins or glue, which, when exposed to fire, will burn and generate a large amount of smoke. Portland cement, which is most often used for production, does not support the combustion process. According to the class, the material belongs to low-flammable substances (G1).
- Biological resistance- cement is not a favorable environment for the proliferation of fungi and insects, so this scourge is characteristic of some varieties wooden houses, bypasses houses made of DSP.
- Good adhesion to finishing materials- cement particle board lends itself well to finishing and plastering. The sheets have good adhesion to the applied finish.
Speaking about the advantages, one cannot fail to mention the disadvantages of cement slabs. Often the choice is in favor of frame construction They do this because DSP is more expensive. Another significant disadvantage is the heavy weight. Work alone in production finishing works It’s difficult with cement-bonded particle board products. Also, significant weight makes it difficult to transport products. Cutting causes certain difficulties, since during this process a large amount of cement dust is released.

Physico- specifications
According to state standards is divided into two brands depending on the quality of the products. At the same time, the main physical and technical parameters do not differ. According to GOST, the density of both brands should be 1100 - 1400 kg/m3. According to the standard, several standard sizes are allowed. The lengths are 3200 and 3600 mm, the widths are 1200 and 1250 mm. Production of other sizes is allowed by agreement with the end user.
Another important parameter is moisture resistance. It consists of basic humidity and moisture absorption, i.e. the amount of water relative to the total volume that the product can absorb. The basic humidity for both brands of product should be from 6 to 12%. According to standards, moisture absorption should be no more than 16%, while the change in thickness (swelling) cannot exceed 1.5%, while for some types of wood-based panels this figure can exceed 20%.
Now from general points we need to move on to the differences.
- TsSP-1- have a smoother surface; for this brand, deviations from the plane of the slab are allowed by only 0.8 mm, oil stains and chipped edges are not allowed. There may be no more than one dent up to 1 mm deep on the surface. The permissible bending strength depends on the thickness of the sheet and cannot be less than 12 MPa for 12 mm thick CBPB; for sheets over 19 mm, the permissible bending strength is 9 MPa.
- TsSP-2 designed for lower bending strength. For a 12 mm slab this figure should be at least 9 MPa, for a slab over 19 mm - 7 MPa. This brand also has more defects. For example, there may be oil and rust stains on the surface, and there may be dents more than 2 mm deep on the surface (the maximum allowable quantity is 3 pieces).
Some materials are often called varieties, although they are not such. It’s just that these products are very similar in production method, structure and properties.
Fibrolite- cement-fiber material, long length is used in production wood fiber, which forms the plates. Fiberboard has low thermal conductivity, fire resistance and is used for insulation. DSP significantly exceeds it in density and strength.
Arbolit It is made from a mixture of shavings, sawdust and wood chips with cement. The material is used not only as thermal insulation, but also for the construction of walls and partitions. Arbolite is produced in the form of blocks, slabs or floors.
Walls made of arbolite slabs retain heat well due to their low thermal conductivity
Xylolite It is made on the basis of shavings and lightweight concrete. The main scope of application is self-leveling seamless floors and partitions.
Selection based on application
It is used as a heat-insulating, finishing and structural material, so the scope of application is quite wide.
- Construction frame house - cement slabs are used for the construction of frame houses. In this role, they replace cheaper, but less moisture-resistant, oriented strand boards. DSPs are used to impart rigidity to the frame and create the structural strength of the house. The distance between the posts should be no more than 60 cm. The slabs allow you to form a “pie” of a frame house, which consists of several layers of sheathing, posts, thermal insulation, vapor barrier and wind protection. The outside of the house is covered with siding or plastered. For walls, sheets with a thickness of 12 - 18 mm are usually used.
Sheathing the house frame with cement-bonded particle boards
- Rough wall finishing- V in this case products made from cement and shavings are used to level the surface of the wall covering. The material is well suited for subsequent painting or wallpapering. In this case, it is better to choose first-class products, with finishing methods when outer side sheets will be covered with other material, products of the TsSP-2 brand are used.
Wall finished with DSP sheets
- Roofing - cement bonded products are used to create a base for soft roof. The sheets are laid on the sheathing or rafter system. In this case, the thickness of the sheets should be selected based on the pitch of the rafters. Most often, sheets with a thickness of 16 to 24 mm are used.
- Subfloors can also be made using cement bonded particle boards, they provide heat and sound insulation. Installation is carried out on logs or concrete screed. This coating most often serves to level the surface before laying the finished floor. Appearance the material does not play a special role, since it will be hidden under the laminate or parquet, so you can use the TsSP-2 brand. In this case, it is important to choose the right sheet thickness, which when installed directly on concrete can be 18 - 20 mm. When installing the log system, it is affected by the distance between the bars. For gaps of 60 cm, it is optimal to use slabs of 20 - 26 mm.
Laying a subfloor on a joist system
has high moisture resistance and can remain in the ground for a long time; this property is used to create temporary floors directly on the ground. Such coverings are used for placing building materials and for temporary buildings.
- Internal partitions allow to differentiate inner space in the house into rooms. Due to its good moisture resistance, the material can be used to divide a combined bathroom into two rooms (bathroom and toilet). If painting is planned as a finish, then it is better to choose a grade of material with the least amount of external defects (TsSP-1).
The partition has complex structure, the frame is made of galvanized profile, used as insulation and heat insulator mineral wool. DSP acts as an element that gives the structure the necessary strength
- Permanent formwork- for pouring foundations or other architectural forms CSP can be used with concrete, they have good wear resistance and tolerate high humidity, while the products are not deformed, so they are not removed when the concrete hardens and perform a form-building function for various structural elements. For example, cement bonded particle boards are suitable for creating columns. Compared to the use of other wood boards (plywood, OSB), the material practically does not change its geometry and does not swell.
Formwork made of cement bonded particle boards
- Window sills can also be made from small cement particle boards. For this, you can use slabs more than 10 cm thick.
- Door trim- due to its moisture-resistant properties, the material can be used for finishing external doors. For example, cement-bonded particle board products are used to improve sound and thermal insulation balcony doors. In addition, the material can significantly increase the fire-resistant properties of the structure.
- Arrangement summer cottage - DSP is used for the construction of fences and fences. The material does not deform from contact with the ground, so it can be used to create beds. Cement slabs are also suitable for the construction of utility rooms for storing tools and gardening equipment.

DSP: classification, selection and scope of application
When constructing any structure, and even more so if it is residential, each of us is interested in not only its safety, but also its environmental friendliness. And therefore, in the construction of houses, they are increasingly beginning to use cement-bonded particleboard.
Thanks to their natural and high-quality ingredients, they do not cause harmful effects neither on human health nor on the environment.
These slabs are used not only in prefabricated structures, but also for internal and external construction work, namely for the manufacture of ceilings, window sills, flat roofs, various storage facilities, communication boxes, mobile boiler rooms and residential containers and much more, which are subject to the most stringent requirements for moisture resistance, soundproofing and fire safety.
DSP board is a universal building material in the form of monolithic sheets with a smooth and hard surface, produced in accordance with the requirements of GOST 26816-86.
Cement particle boards are made from cement, tree shavings coniferous species, minerals and water. Due to the presence of silicate cement, there is no need to use synthetic glue, and therefore there are no such harmful substances such as phenol, formaldehyde, etc.
Additional information on use is available in the collection of articles. The most low price DSP from leading manufacturers.
ANY CUTTING OF CEMENT PARTICLE BOARDS TO CUSTOMER SIZE.
When choosing cement bonded particle boards, you need to consider where they will be installed. Standard DSP dimensions: length 3200 or 3600 mm, width - 1250 or 1200 mm.
When choosing the thickness of the sheet, it is necessary to take into account that as the thickness of the sheet increases, an additional load on the structure occurs, and at the same time, under high loads and impacts, the cement-bonded particle board may break. Based on all this, the recommended thicknesses are:
20 mm - 36 mm - for installing canopies, window sills, etc.
10mm -20mm for permanent formwork
8 mm for subfloors
From 12 to 36 mm for frame construction
10, 12 mm for partitions
12, 16 mm for external cladding

Application of cement-bonded boards
What's new in area modern production DSP?
New technology production of cement bonded particle boards allows you to obtain products with extremely low thickness variation. This development of events became so successful that in this regard, there has been a steady demand for the sale of CBPB boards with a thickness 4 mm. This is the minimum tthickness for them, which can be produced. The first batch of 6 mm slabs is produced in Magdeburg and was so high quality that all the plates were within thickness tolerance± 0.2 mm. Such fine tolerances make the costly grinding process unnecessary. In addition, the plates have smooth surfaces consisting from very small particles, and
particle sizes gradually increase towards the center boards Not new, but not so widely yet famous csp board with embossing and surface coating in various configurations
, such as brickwork, wooden boards
or a natural stone.
Especially in Japan has a large number of people willing to buy CP these boards made the sale of csp Very successful business. More than 90 % of Japanese buy such slabs from embossed and surface coated and used for cladding external walls.
Based on success in Japan, several companies in many other countries have started test market for the sale of chipboard. In its simplest form, paint is applied to the surface usually with a roller or spray required colors, for which currently availablevarious suitable paints and coatings. In a higher quality version, the coating is performed from reinforced hard plastic with relief the surface that results so tough and durable that it can match the strength become.
Where to buy DSP sheets?
Not entirely new, but very interesting, is the use of cement particle boards as tiles. In Hungary, the use of painted and unpainted tiles on walls and roofs is common, but of particular interest are roofs and walls made from tiles developed in some states in the western United States. It undoubtedly looks beautiful, but is flammable. Nevertheless, the sale of CP is in full swing.
Very interesting is the successful application large sizes prefabricated walls and floor elements assembled from DSP panels. All elements consist of panels arranged in composition with metal or high-strength plastic spacers and have the necessary internal reinforcements. Each piece is precisely cut to exact dimensions in the factory, including openings for cables, pipes, ducts, doors and windows. On site, prefabricated elements only need to be installed and filled with concrete. Before the concrete is poured, water, gas and electricity piping will first take place in the wall cavities. After the construction of the building, the external walls are insulated with 7 cm thick polystyrene foam sheets, which are covered thin layer plaster or resilient finishing. Only three workers are needed to install all the walls and floors for single-story buildings per week. Thanks to the prefabricated structure system, it is fast, high quality and affordable price of csp per sheet. This efficient method of constructing a building does not create a lot of dust, waste and normal noise in the area. construction site, and provides a quick return on investment. DSP with a thickness of 10, 12 and 16 mm are used as external and internal lining walls (on a lathing frame), cladding of columns or crossbars of public, industrial and agricultural buildings.
Moisture-resistant partitions - DSPs with a thickness of 12 and 16 mm are used in rooms with high humidity. This is due to the corresponding physical and mechanical properties of the material. DSP can be used in partitions of sanitary units of buildings for various purposes.
Interior wall decoration - DSP, having certain fire-retardant properties, is an environmentally friendly and moisture-resistant material, and therefore is successfully used for interior and exterior finishing residential and public buildings with dry and normal operation.
Floors - DSP with a thickness of 16, 24 mm can act as the following floor elements: a base for various coatings, an underlying layer, a leveling layer, a finished floor with a top coat. DSP with a thickness of 24 mm can be used for the construction of prefabricated floors on bulk foundations in warehouses and utility rooms. This eliminates wet processes, which allows work to be carried out at negative temperatures. In addition, slabs can replace cement screed. The advantages of this solution are: reduction in labor intensity; opportunity to lead renovation work without stopping production. The 8 mm thickness is also a popular position and is constantly available in our warehouse.
Removable, permanent formwork - slabs with a thickness of 12, 16 and 24 mm can be used as removable or permanent formwork for constructing building foundations. The simplicity of the formwork design will reduce labor costs and achieve a significant reduction in cost when performing zero-cycle work.
Window sill board - 24mm thick CSP window sills are ideal for any modern interior. According to its characteristics, a window sill made of CSP is stronger and more durable than its wooden counterpart.
Over the past decades, dry installation technologies have increasingly been used in residential and civil construction. They can significantly improve consumables and raise the level of quality of work performed. In practice, inexpensive and safe cement particle boards are often used. Studying the technical and operational characteristics, areas of application, as well as consumer reviews and a review of current prices will help you understand the benefits of working with this material.
The building element is monolithic slab, which contains the following substances:
- cement – up to 65%;
- coniferous tree shavings – about 25%;
- water – 8.5%;
- additives – 2.5%.
The prepared components are mixed and placed under a press. The formed sheets are heated to 90°C for 7-8 hours, then cooled under natural conditions. Final hardening occurs after about two weeks.
Special additives (antiseptics, plasticizers, hydration admixtures) help improve the quality characteristics of the DSP and enriching them with new properties.
The use of natural raw materials in the production makes the panels absolutely safe for humans. Houses built from slabs are strong with smooth internal and external surfaces. The walls allow air to pass through well, which contributes to the formation of an optimal micro-regime in the rooms.
The slabs can be easily subjected to various types of processing:
- cut to achieve the desired size;
- drill holes;
- milling to obtain parts of arbitrary shapes;
- grind the ends to ensure joint strength.
Many finishing options are applicable on the surface of DSP panels:
- painting work with the application of primers and paints made of silicone and acrylic;
- pasting with vinyl trellises or glass wallpaper;
- facing with ceramic tiles.
Externally, the panels are very similar to chipboard (chipboard). These materials should not be confused, since CBPB contains more cement, which means it is much stronger. In addition, it has versatility of use.
Technical characteristics of DSP
- Dimensions.
The thickness of the plates is in the range of 8-36 mm. Geometric dimensions are determined regulatory documents and are: width 1200/1250 mm, length 2600/2700/3200 mm. By pre-order, the company can produce any, for example, with a length of 3000 or 3600 mm.
- Density.
At a relative air humidity of 6-12%, the figure is 1300 kg/cm2. The maximum swelling of DSP sheets is up to 2%. The maximum water absorption standard is no more than 16%.
- Roughness.
The relief of the panels depends on the degree of surface treatment with grinding equipment. According to GOST, the roughness of untreated CBPB elements does not exceed 320 microns, and polished ones – up to 80 microns.
In practice, there is a cement-bonded particle board with a thickness of about 4 mm. She doesn't demand additional processing surfaces, which has a positive effect on the final cost of products.
Where are DSP panels used?
Material made of cement and wood shavings is a high-strength construction base with good performance environmental friendliness and sustainability. It is widely used in the construction and reconstruction of civil, industrial and agricultural facilities.
DSP sheets form an excellent basis for modular construction. With their help, heat-saving and sound-absorbing walls are created in frame houses. The slabs perfectly level the base of the floor and make it warm, which significantly increases its service life. Dimensional accuracy facilitates faster installation of panels into the frame.
It is advisable to use such slabs in the construction of permanent formwork, fencing, and facade finishing. This greatly reduces work time, provides structures with the necessary reliability and saves overall construction costs.
Excellent performance characteristics do possible use slabs for floors, walls and ceilings in wet rooms, such as a bathroom or sauna.
Advantages and disadvantages of DSP panels
The main advantages of using the material:
- high strength;
- absence of toxic and carcinogenic components;
- thermal protection;
- moisture resistance;
- resistance to biological aggression, insects and rodents;
- good sound insulation;
- operation in various climatic conditions;
- acceptable cost.
Feedback from experts confirms the small number of shortcomings of DSP panels.
- Large mass complicates the transportation and installation of elements, which somewhat slows down the work process.
- Brittleness when bending - a smooth base is required for laying slabs. It is advisable to buy building material with a margin of 10-15% more than planned by the estimate.
- Limited service life - only valid under severe operating conditions.
Negative aspects lead to a slight increase in the cost of construction work.
When purchasing Supplies should be taken into account various characteristics slabs
Sheet selection optimal size depends on the installation location. It should be remembered that an increase in product parameters leads to an increase in the total load on the structure. Therefore, for flooring it is better to buy sheets with a thickness of 8-20 mm, for façade cladding choose 12-16 mm, and for canopies, window sills, and countertops, 20-36 mm is suitable.
The type of front surface matters when finishing interior walls and facade. Manufacturers offer a wide range of panels with smooth and corrugated coatings that imitate marble, quartz, and sand.
Consumer reviews
“I have been professionally engaged in construction work of varying complexity for many years. I noted many advantages of using slabs. In particular, a minimum of time is spent on finishing the facade. Thick panels are easy to cut circular saw with a disk for wood, thin with a regular hacksaw. Installation on the frame is also convenient for mounting by making holes with a regular drill. No tension is required, the panels are durable, can be laid quickly, forming smooth surfaces.”
Andrey, Yaroslavl region.
“I gained my first experience using DSP while tiling a garage. It turned out that the slabs were not at all difficult to cut and attach. Painted the finished walls acrylic paint, it turned out well. Now it’s time to install the floor in the kitchen. There is one significant drawback: It is profitable to buy material only in large quantities. The retail price of the sheet is much more expensive. So for small volumes of work, DSP is not worth using.”
Ignat, Moscow.
“According to the designers in country house Marble window sills were planned. The price turned out to be too high, so they decided to replace the natural stone with an imitation of cement bonded particle board. It turned out to be a great pleasure to work with such material - it can be easily sawed with a hacksaw and sanded with a plane. I was pleased with the result, and my friends are still confident that we have real marble.”
Victor Tretyakov, Leningrad region.
“Based on reviews from the Internet and the advice of friends, I decided to try DSP panels for flooring. First, a thick slab was laid on a layer of crushed stone. Then insulation, waterproofing and joists with cross members. Thin 16 mm slabs were used on the subfloor, and linoleum was laid on top. It turned out inexpensive, smooth and warm. The floor does not allow moisture to pass through and breathes well.”
Nikolay, Stavropol region.
“I wanted to build a fence at the dacha from corrugated sheet metal. I calculated the expenses in advance and it turned out to be a large sum. I started studying the characteristics of other materials and came across DSP. The material turned out to be much stronger and cheaper. I installed the supports myself, welded metal profiles to them and secured the sheets with self-tapping screws. It turned out durable and beautiful fence. Manufacturers assured that the material is very strong and does not rot. I’ve had it for five years now and have no complaints.”
Evgeniy, Ekaterinburg.

Products are manufactured in accordance with GOST, which strictly regulate the composition. Thus, the components should include 65% Portland cement, 24% wood chips, 8.5% water, and 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 at special equipment under factory conditions, as evidenced by the quality certificate, as well as the 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 known before purchasing, is of 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, the use of which 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.
