Among the slab and sheet materials used for finishing and construction of partitions and various design elements, you cannot ignore the 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. In addition, if you install permanent formwork using cement- chip material, then, in fact, you will get a finished finished foundation or other structural element of the building. 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 a finishing material. Fortunately, manufacturers today offer a huge assortment with design to suit 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 that improve specifications slabs (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 manufacturing 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 particle board 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, and use not a simple cutting tool, but a diamond one.
• 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 about external finishing with DSP boards. A standard steel profile is required here.
• When cutting slabs, a large amount of dust is released, so this operation should only be performed outdoors.

What is DSP? Why is it needed? Where and why is DSP used?

We will answer all questions in this article.

So, what is DSP?

CSP (cement particle board)– this is a new generation material. It is strong, moisture resistant and durable! Let's find out why.

As the name implies, CBPB is made from cement and wood shavings. Cement resists fire well, and wood shavings prevent the slab from cracking in frost or heat.

In addition, cement particle boards have excellent heat and sound insulation properties. This makes this material universal for carrying out external and internal work in different climatic conditions. The material is as easy to work with as with conventional timber. But unlike wood, cement board is reliably protected from damage by insects and rodents, and is practically not afraid of fungal formations.

Advantages of DSP

Environmental friendliness

The main chemical binder in CBPB is the cement itself. This material does not contain any phenolic, formaldehyde or other toxic compounds.
The slabs are made by pressing a mixture of wood chips, cement, minerals and water. Indeed, CBPB is environmentally friendly pure material.

Fire safety

During indoor fires, DSP boards do not generate smoke or emit toxic gases or vapors. Cement is generally considered a non-combustible material. AND,
If CBPB boards are compared with the well-known OSB, then CBPB clearly wins.

Biostability and moisture resistance

DSP contains antiseptics that help resist the effects of various fungi, beetles, rodents and other living creatures.
Biodestruction of CBPB boards is not observed even with prolonged exposure to moisture.

Frost resistance

Perhaps the most important advantage of CBPB is frost resistance, which expands the geography of use of cement particle boards. Thus, the standard value for the reduction in bending strength after 50 cycles does not exceed 10%. In practice, the value of this indicator is lower. Long-term experience in using structures with TAMAK CBPB in buildings for various purposes in Yakutia and Khanty-Mansiysk has confirmed the high performance properties of the material.

Reliability

TAMAK CBPBs tolerate changes in temperature and humidity levels well over a long period of time. This ensures a wide geography of application and durability of structures.

Application of DSP

Construction and insulation of buildings

One of the most popular types of work using cement particle boards is the insulation of buildings of various types. IN frame construction Installation of cement bonded particle boards allows you to perform two tasks at once. With their help, both the external and internal surfaces of the building are formed. The slabs are attached directly to the sheathing frame.

Typically, 12-16 mm thick CBPB boards are used, which must be attached to the sheathing. It is best to choose the size and material of the sheathing and strictly follow the manufacturer’s recommendations. For this type of work, it is recommended to use mineral slabs(mineral wool). You need to leave a small gap between the plates, no more than 10 mm. It must be insulated with elastic mastic or a sealing gasket. Such a gap needs to be closed from above, for example, with the same cuttings of DSP.

Internal work with DSP

Cement particle board is a completely safe and environmentally friendly material. DSP boards are recommended for use in interior decoration of any type of premises. These slabs are used to quickly and efficiently level the wall. They can be mounted on a wooden sheathing made of timber or metallic profile. To do this, use nails, screws and self-tapping screws. After this, the slabs can be faced, plastered, painted or other work carried out. This finishing significantly increases the level of fire safety.
DSPs are also excellent for forming internal partitions, especially when it comes to moisture-resistant partitions. While ordinary chipboard is well suited for an ordinary screen, such material will not withstand long in conditions of high humidity. In order to increase the service life of such a partition, it must be painted with recommended moisture-resistant paint. Particular attention should be paid to the edges of the slab; they must be treated with a special moisture-repellent agent.

DSP floor and roof
The rule of good form is to use DSP when laying the floor or forming roofing pie instead of outdated chipboards.

There is no need to change technology at all. Usually the floor is arranged on logs with a section of 50x80 mm and a pitch of about 600 mm. For this type of work, more durable slabs with a thickness of 20 to 26 mm are used. With their help you can lay a base under the floor, sf form an underlying or leveling layer. DSP is also used for bedding heated floors and clean floors with a face coat. Separately, it should be noted that it is possible to lay the floor from cement bonded particle board 24 and 26 mm thick directly to the ground. This allows the construction of warehouses and utility rooms on bulk soil, even when negative temperatures. That is, the costs of repair and auxiliary work are significantly reduced. Firstly, there is no need to select the right time and temperature, secondly, laying such a floor can be done in a short time, thirdly, with a minimum of financial costs, a full-fledged workroom is obtained.

As for the soft roof, despite the increased moisture resistance building material, it is necessary to strictly monitor waterproofing. The main danger for any roof is water that has penetrated and accumulated inside. If the damage is not detected in time, then
the consequences can be very different. Therefore, the joints between the slabs must be protected with strips of sheet material. After this, they are additionally reinforced with strips of protective roofing material. And only after that a protective coating is applied. roll covering onto the roof itself. But in general, the process of forming the foundation for soft roof using DSP is practically no different from working with similar wood materials. Depending on the building design, slabs with a thickness of 16, 20 and 24 mm are used.

External works with DSP

Cement bonded particle boards are often used in outdoor applications. The simplest example is cladding metal doors. Select and attach the slab required sizes it's possible even without preliminary preparation. Excess edges can be easily removed hand tools. Sheathing can be carried out both externally and externally. inner sides s. This will significantly increase the sound and heat insulation of the room, and also give the door fire-resistant qualities. One 20 mm thick DSP board can hold a flame for 50 minutes. It is recommended to use this material for fencing a balcony or loggia. Typically used for this purpose asbestos cement sheets, but this material is very fragile. This complicates its installation and leads to rapid failure during operation. By using DSP to fencing your balcony, you get a strong and durable structure.

IN Lately Window sill boards began to be produced from DSP. The size of such a board can be very different. They are usually made directly on the construction site, depending on the size of the window. Minimum thickness such boards are 10 mm, maximum - 26 mm. This technology is characterized by the following advantages: low price, durable smooth surface, absence of joints, dimensional stability. When pouring the foundation, cement-bonded particle boards are increasingly used as formwork. This technology has proven itself well in low-rise construction. Typically, slabs with a thickness of 12 to 26 mm are used, depending on the size of the foundation. In this case, the plates perform two functions at once. Firstly, their use can significantly reduce labor costs and work time, because installation of this building material is as simple as possible. Secondly, if outer part paint the slabs with special paint, then they will take on the function vertical waterproofing. But the main thing is that the DSP is strong enough not to deform during pouring and hardening of the concrete mixture.

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 designs are presented in great variety on 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 according to 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;
• on 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 undergoes heat treatment, during which the characteristics of the raw material components are taken into account;
• 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. It is impossible to independently produce a high-quality DSP panel.

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 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 different types of materials for slabs and cast products made 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 effect on this type of DSP.
• Fine-chip materials include wood concrete, which is used in various fields.

Advantages and disadvantages

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.
• A wide range of. In modern construction stores you can find a wide variety of products.
• The affordable price is an 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 renovation work using a drill, hammer drill or knife.
• The fixed size of the products significantly simplifies the installation process.
• The material is resistant to rotting processes.
• When a cement-bonded particle board is used to screed floors, it contributes to significant cost savings compared, for example, with self-leveling compounds or a cement-sand leveling option.

TO negative properties DSP can be classified as:

• 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. Risk of breakage 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. It is also possible that work to implement permanent formwork. DSP sheets can be used both in private and industrial applications. These slabs are used to construct both protective structures for garden beds in private homes and parts for industrial enterprises.

• Cement particle board is indispensable in the construction of a 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 a ceiling covering in saunas and other types of rooms 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. Can be carried out the following options processing of cement-bonded products:

• cutting to required sizes;
• creating holes in slabs using a drill;
• milling work;
• increasing strength at joints using end grinding;
• applying a primer mixture, acrylic or silicone paints;
• cladding with ceramic products;
• pasting with glass wallpaper.

These capabilities characterize the DSP material as an excellent base for any coating and as a source for the embodiment of creative ideas.

Manufacturers

There are a number of manufacturers of chipboard products that are very popular in the construction market and have earned positive customer reviews.

Leningrad company "TSSP-Svir" provides light gray products with a calibrated surface. Also among the company's assortment there are polished models. The production is based on European standards and high-quality equipment from Germany.

Bashkir enterprise "ZSK" is also distinguished by the production of high quality slabs in accordance with GOST. The main feature of the product is its increased resistance to temperature fluctuations and the influence of weather conditions.

Kostroma company "MIT" characterized by special geometric characteristics of the product and strict adherence to all quality standards.

Tambov company "Tamak" produces high quality slabs. The company approaches its business very carefully, so it is difficult to find even the slightest defect among their products.

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 the correct installation of these boards.

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. You can attach alternative ways– using mastic or a special adhesive solution.

To insulate a frame structure, slabs must be installed on the outside and inside of the walls simultaneously. If you want to insulate a utility room, then it is permissible to leave 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.
• Room measurements are taken taking into account the location long side cloths across the boards.
• It is necessary to design a diagram on paper 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 flooring.

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.

How to quickly and efficiently, but at the same time with minimal waiting time, level the floors in an apartment or house? If the speed of work is very important, and even the creation of a regular cement screed impossible, then a DSP board is perfect for this purpose. The use of this building material for flooring allows you to make surfaces smooth very quickly. In this case, the coating will be durable and of high quality.

DSP board - application for flooring

DSP is a cement-bonded particle board, and the name fully reflects the composition of this material. DSPs are made from a mixture whose components are wood shavings and cement compounds.

The building materials include:

• wood shavings with fractions various sizes – 24%;
• water – 8.5%;
• special additives – 2.5%;
• Portland cement – ​​65%.

The production process is quite simple - DSP is made as follows.

1. Special mixers are loaded with special aqueous solutions which include various salts, liquid glass and aluminum.
2. Next, wood shavings with fractions are gradually added to these solutions different sizes– mineralization of raw materials occurs.
3. Cement is mixed into the resulting composition and a little more water is added.
4. The mass is thoroughly mixed until smooth and then goes under a powerful press.

GOST 26816-86. Cement particle boards. Specifications. Downloadable file (click the link to open the PDF in a new window).

The result of this production chain is a finished cement bonded particle board, which is quite thin and has a smooth surface. A large amount of cement in the composition allows you to create a fairly durable material. By the way, inside the slab the chips have O larger dimensions than outside, due to which a smooth surface is achieved finished material. DSP does not need to be further leveled after installation, making the material excellent for creating rough flooring for laminate, tile and other types finishing. Also, no voids are formed inside the DSP during production.

On a note! Wood shavings are also used as raw materials for chipboard production, fiberboard and OSB boards. The technologies for producing these materials are somewhat similar to the technology for producing CBPB boards.

DSP boards are widely used in construction. They can be used for finishing façade walls houses, from which various partitions are created indoors. The material is suitable for use for restoration purposes and for interior finishing work. Moreover, it is suitable for both apartments and private houses.

The DSP board is characterized by high environmental friendliness, as it is created from natural natural materials and contains virtually no additional chemical ingredients. That is why the stove is recommended for use both in residential premises and in production.

Using a cement bonded particle board is an opportunity to avoid the labor-intensive pouring of cement screed to create a base. The building material allows you to reduce labor costs and spend less money from the budget planned for leveling floors for laying the finishing coating.

DSP plates

Characteristics of CBPB boards

DSP is a completely new category of material, characterized by significant strength, long service life, and a certain level of moisture resistance. It also has good soundproofing and heat-saving properties. All these features allowed CBPB boards to take a strong place in construction industry- They are used for various purposes.

Of course, this material is far from ideal, but still, thanks to its properties and characteristics, it can be used both outside and inside the building. The DSP board does not lose its qualities in a wide variety of climatic conditions.

On a note! Compared to chipboard, which is common for many, a board based on cement and shavings is 3 times stronger and has high resistance to various physical influences and loads.

The density of one cubic meta CBPB board is quite high - about 1300-1400 kg/m3. The moisture content of the material is 6-12%. By the way, the material is not 100% protected from the effects of water, but swelling upon contact with liquid over a full day should not exceed 2%.

The slab is rough to the touch, but smooth - often these indicators depend on the grinding method used. Sometimes the DSP does not need the latter - if the roughness level is no more than 80 microns. The plate is selected in accordance with the operating conditions, as well as the requirements for the final results. For example, smooth slabs are usually used indoors, but rougher slabs can be used outside.

On a note! Finishing of DSP boards is simple - any type of floor finishing can be laid on them, and paint, varnish, plaster, etc. can be easily applied to the surface.

Cement particle board - transportation

Advantages and disadvantages

What are the main advantages and disadvantages of slabs over other similar materials? Let's look at the answer to this question in more detail.

Advantages of DSP:

• environmental friendliness of the material, as it is made from natural ingredients. DSP does not contain asbestos and formaldehyde-containing substances;
• fungus and mold do not settle on the slabs;
• the material is not hygroscopic - this is its main advantage over chipboard;
• DSP does not suffer from temperature changes and does not lose its performance qualities;
• 100% non-flammability of DSP boards allows them to be used in any room. The material can withstand fire for 50 minutes;
• reasonable price, allowing you to purchase material even if you have a small budget;
• significant strength due to multi-layer material. Excellent performance is observed under pressure both from the end of the plate and from any of the other sides;
• the slab does not require additional leveling of surfaces;
• the material is not afraid of chemical influences;
• cement particle board perfectly resists rotting processes;
• relative impermeability to water - during the day, DSP is able to absorb a maximum of 16% of liquid;
• high noise insulation and heat insulation qualities;
• ease of installation.

On a note! It is recommended to use DSP boards when installing a water heated floor system. In this case, it will be possible to create an additional air gap between heating and finishing coat, which will significantly improve the result of the work done.

The disadvantages of plates are as follows:

• large mass of material, which makes working with it difficult;
• During processing, the DSP generates a lot of dust. If you have to cut slabs, you should wear a respirator and safety glasses to avoid harm to your eyesight and respiratory organs.

However, the material has many more advantages than disadvantages, which explains its popularity in construction, including for leveling floors. Typically, CBPB slabs are laid on logs - this is best option application of the material in this area. More often, DSP is installed under laminate, carpet, linoleum, and ceramic tiles.

In general, it can be noted that in most respects, CBPB boards are superior to plasterboard, chipboard and fiberboard, which makes them one of the best building materials. Also, DSP will save a lot of money if a choice is made in their favor.

DSP in insulation works

Most often, DSP is used in the field of insulation of buildings and structures. Usually the material is sheathed on the outside of the building. Fixation is done using self-tapping screws or nails.

But, since DSP is an environmentally friendly material, wall and floor cladding can also be done from inside the room. The sheathing process is similar to what is done outside: the material is attached to a wooden or metal sheathing using nails or self-tapping screws. Sometimes adhesive mastics can also be used. After installation of the slabs, finishing is carried out.

Application for floor

DSP is often used to create a subfloor. Most often, the material is laid with the expectation that in the future it will be glued to it. ceramic tile– this is the most demanding coating regarding the evenness of the base. DSPs are also suitable for pouring and installing soft floor coverings.

DSP slabs can be mounted on logs, and also laid on flat concrete or wooden base. The material lasts for many years and is able to withstand significant loads if installed correctly.

Choosing cement sheets for the floor

The choice of DSP boards is carried out in accordance with the conditions in which the material will be used, as well as the technology by which its installation will be carried out. For laying on logs, slabs with a thickness of 20-26 mm are used - they will cope with their function perfectly rough foundation. If installation is carried out directly on the ground, then 24-26 mm slabs are used. In general, almost any DSP board can be used to level floors.

On a note! DSP boards can be laid even in cold weather. It doesn’t matter if the air temperature outside the window drops below zero.

Requirements for CBPB slabs used for floor installation:

• humidity – from 6 to 12%;
• density – more than 1300 kg/m3;
• tensile strength – 0.4 MPa;
• surface roughness – 80 microns;
• moisture absorption level – 16%.

Preparing for the installation of a DSP coating

Before starting work on arranging a rough surface made of CBPB, the base of the floor must be properly prepared. For example, when laying material on a wooden base, old or rotten boards must be dismantled and replaced with new ones. It is important to seal all the cracks with putty, and the wooden base is primed for better adhesion to the glue on which the slab covering will be mounted.

If installation will be carried out on a concrete base, then it should also be carefully inspected for damage and repaired if necessary. Also, if there are strong horizontal deviations, alignment is performed cement mixtures. In the case of laying CBPB on the ground, it is necessary to first level the surface - this can be done by pouring it onto the ground sand and gravel mixture 20 cm thick and compacted it.

The best option is to lay CBPB slabs on logs. In this case, if it is planned to install the foundation directly above the ground, supports for the logs are installed on the ground, and hydro- and thermal insulation is also laid. The distance between the supports can vary from 0.5 to 1 m - this indicator depends on the thickness of the timber used for the logs.

Materials and tools that need to be prepared for working with DSP:

• timber for logs (section 150x100 or 50x100 mm);
• DSP boards in the required quantity;
• antiseptic solution for timber;
• sawing tool (for example, a hacksaw);
• materials for waterproofing and insulation;
• tools for taking measurements (tape measure, pencil);
• fastening material;
• drill.

Arrangement of the floor using DSP

Let's consider the arrangement of a floor made of cement-bonded fiberboard on joists using the example of a balcony.

Step 1. A layer of insulation is placed under the joists. The logs are installed parallel to the walls at a distance of about 30-40 cm from each other.

Step 2. Cross bars are installed and the sheathing is created. Between themselves wooden blocks connected using metal corners and self-tapping screws.

Step 3. The space between the joists is filled with insulating material.

Step 4. DSP boards required sizes laid across the longitudinal joists. The width of the piece of material should be slightly less than the width of the balcony (by 5-10 mm).

Step 5. The slabs are fastened with self-tapping screws to the joists. The gaps between the DSP boards are sealed with an adhesive composition.

DSP floors: laying nuances

In general, the installation of CBPB boards is carried out in exactly the same way as the installation of OSB boards. When carrying out work, it is important to follow several rules, and then the base of the floor will be made of the highest quality:

• wooden beams for logs must be treated with compounds that prevent rotting. Special compounds can be replaced with machine oil;

• when installing slabs on concrete screed for logs you can use timber of a smaller cross-section - up to 50x50 mm. This will save useful space;
• when installing logs, you should monitor their level - it must be strictly horizontal;
• before installation, the CBPB boards are laid out along the joists - this will allow you to determine which of them need trimming if necessary;
• the glue must be mixed well before use;
• Compensation gaps along the walls will allow you to avoid deformation of the DSP base.

DSP is a pretty good material if you use it to create a flat base. It is not difficult to work with it, but due to the large mass of sheets, it is better to get an assistant.

In the modern building materials market, various sheet finishing materials are presented in a wide range. This is chipboard and OSB boards, various types of plywood, drywall and other modifications. Despite this, the DSP board, the use of which is not limited only to interior work, deserves special consideration.

The unique structure of the material, which consists of seemingly incompatible ingredients, provides DSP with characteristics that are not only not inferior to analogues, but also superior to them in some respects. Relatively low cost, strength and reliability, weather resistance and ease of installation make the material indispensable for any construction and repair work.

In most cases, for the installation of DSP boards, the use of a wooden or metal frame is necessary, so it is worth stocking up on the necessary material and fasteners in advance.

What is a DSP board?

Wood chips and cement are used to produce this unique building material. The wooden filler is pre-crushed and sorted, after which it is antiseptically treated with calcium and aluminum chlorides. The components are thoroughly mixed, and the resulting mass is poured into special molds. As a rule, the composition of a cement-bonded particle board (CSB) includes:

• Portland cement - 65%;
• Wood shavings - 24%;
• Water - from 8.5 to 9%;
• Hydration and mineral supplements - from 2 to 2.5%.

To reduce internal stresses and more efficient pressing, a small amount of fuel oil or industrial oil can be added to the prepared mixture. The filled forms are stacked and pressed. Working pressure can vary from 1.7 to 6.5 MPa. To accelerate hydration and hardening of the mixture, it is subjected to intense heating for 8 hours.

Important!

The elasticity of wood chips compensates for the shrinkage of cement, therefore, even during the drying process, the dimensions of the slabs remain unchanged.

After removal from the formwork, the CBPB board is transported to a technological warehouse, where it finally dries under natural conditions. The final stage of production is hot air blowing, cutting, polishing and delivery to the storage location.

DSP board: technical characteristics

Before using the material, it is necessary to study its basic operational and technical characteristics. Currently, according to GOST 26816-2016, the domestic industry produces two types of CBPB boards, the characteristics of which are given in the table:

Options	TsSP-1	TsSP-2
Bending elasticity index, MPa
Surface hardness, MPa
Thermal conductivity of the material, W/(m °C)
Specific heat capacity, kJ/kg °C
Specific resistance to fastener removal, N/m
Frost resistance of the material
Number of freeze/thaw cycles
Residual strength, %
Resistance to changes in humidity and temperature
Strength reduction (20 cycles), %
Increase in sample thickness (20 cycles), %

Such performance characteristics allow the material to be used in a wide variety of areas of repair and construction work.

Scope of application of CBPB boards

As mentioned above, DSP boards, the use of which ensures high mechanical strength of the structures being created, are widely used in construction, repair and finishing works, in particular:

• In the manufacture of formwork foundations and other monolithic reinforced structures. The use of DSP significantly simplifies the installation process; in addition, this design prevents concrete leakage and ensures the formation of smooth side walls that do not require subsequent plastering.
• When covering walls and erecting . In most cases, DSP sheets are attached to a pre-assembled metal or wooden frame. The thickness of the sheets in this case ranges from 8 to 12 mm. For fastening, self-tapping screws are most often used; it is also possible to use screws or nails as fasteners. In some cases, when leveling walls, special adhesive polymer mixtures can be used.
• Application of DSP boards for flooring provides high mechanical strength, as well as high thermal, hydro and sound insulation. The thickness of the material is selected based on effective loads and the distance between the lags, however, the use of CBPB boards with a thickness of less than 14 mm is not recommended.
• Application for facade at home allows not only to significantly reduce the time required for work on exterior decoration, but also provides high-quality waterproofing of the main walls. Another advantage is that when using DSP, the characteristics of the material make it possible to create various types of ventilated facades. As for the sheet thickness, for outdoor use it can vary from 12 to 14 mm.

DSP board: sizes and prices

Regardless of the brand, TsSP-1 or TsSP-2 (GOST 26816-2016), the sheet size can be:

• Thickness: 8-40 mm, in 2 mm increments;
• Length: 2700/3200/3600 mm;
• Width: 1200/1250 mm;

Depending on the thickness and overall dimensions, the weight of the sheet can vary significantly:

Overall size, mm	Weight, kg

The table shows that the DSP sheets large thickness They have a significant mass, therefore, when working with them, it is advisable to use various lifting devices.

Methods of fastening DSP panels

Depending on the thickness of the DSP sheet and the type of work performed, the fastening can be:

• With open seam on screws;
• With open seam on nails;
• With closed seam on screws;
• With closed seam on nails;
• Using aluminum profile;
• Using a decorative strip.

The last two methods are most often used for decorative processing of facades.

Types of DSP: characteristics and their application

Depending on the structure of the wood filler, features and, a number of modifications have been developed based on DSP:

Fibrolite . Thin long shavings are used as a connecting element coniferous species. The mechanical properties of the filler contribute to an increase in fiberization rates, which significantly increases the strength and elasticity of the material. The surface hardness of the semi-finished product is slightly less than that of CBPB. As a rule, fiberboard serves as good sound insulation.

A rbo lit . Wood processing industry waste, dry reeds and even cereal straw are used as filler. Despite the fact that the manufacturing technology remains unchanged, the strength is noticeably lower than that of CBPB. The main area of ​​application of the material is cladding load-bearing frames internal partitions, heat and sound insulation.

Xylolite . Sorel cement provides high resistance to moisture and water. Thanks to this, the material has become widespread in façade cladding. Laying rough floors and installing roofing coverings.

How to prime DSP

Before you start final finishing surfaces made of CBPB, it must be treated with a primer, preferably deep penetration. For interior work, you can use the time-tested primer Ceresit ST 17, but its cost is quite high. There are other deep penetration acrylic compositions that are not much inferior to CT 17 in quality, and their cost is noticeably lower.

You can make a primer yourself by carefully dissolving 1 kg of PVA glue in 10 liters of water. This mixture is significantly inferior to deep penetration primers, but still better than nothing.

For processing facade cladding from DSP, the use of a special primer is mandatory, otherwise the painting will end in disaster very soon. As a primer, you can use a 10% solution of acrylic facade paint.

How to paint a DSP board

To give the DSP boards an attractive appearance, the most in a simple way is coloring. After appropriate preparation of the surface, apply two layers of paint using or. Most often, in order to paint DSP, they use:

Acrylic paints . This paint has good adhesion and is highly wear-resistant. If financial capabilities allow, it is better to use paints that contain a solvent, but also water-soluble facade acrylic paints, when correct application, will last from 3 to 5 years.

Latex paint . This coating is resistant to alkaline and weak acid solutions and is easy to wash and mechanically clean with detergents. Besides. Painting works You can do it yourself, which will save you a significant amount.

Silicate paint . The use of this type of coating has high adhesion, their vapor permeability provides optimal conditions for air circulation, which prevents the appearance of mold and other fungi. The coating is resistant to weather conditions and detergents, and its service life will satisfy even the highest requirements.

Before you start painting DSP, it is necessary to take into account that the use alkyd paints undesirable, since direct contact with alkalis may cause cracking and peeling of the coating.

Advantages and disadvantages of using CBPB

Like any material, DSP, despite its undeniable advantages, also has some disadvantages; let’s take a closer look at the pros and cons of DSP panels, the characteristics of which were given above. The advantages of the material include the following properties:

• High strength;
• DSP sheets, even with a small thickness, provide a high degree of sound insulation;
• Cement particle board does not burn even at very high temperatures;
• Even without additional processing, it has antiseptic characteristics;
• Vapor permeability;
• Water resistance.

The disadvantages of the material are less significant:

• Large specific gravity of the slab, making installation work difficult;
• Insufficient strength under bending loads;
• Difficulty in cutting and increased and large amounts of dust when cutting with power tools;

In order to draw final conclusions, it will be useful to study reviews on the Internet; here are some of them.

Cement particle board: consumer reviews

Positive reviews confirm the above advantages of the material:

1. I decided to use DSP boards for the flooring. On crushed stone cushion laid a slab 26mm thick. After that, I laid down waterproofing and mineral wool, and attached the joists. The subfloor was laid with 16 mm slabs, on top - regular linoleum. I am very pleased with the result, dry and warm. Nikolay, Stavropol region.
2. Family circumstances forced us to establish interior partition. The drywall seemed not strong enough, so I decided to use 8 mm DSP. Installation on wooden frame 50x50 mm did not take much time, and cutting was not very tiring. All that's left is to putty and wallpaper. The design turned out to be strong and reliable, very pleased, good material. Andrey. Kharkiv.

Negative reviews contain the most complaints about heavy weight material and other difficulties during the installation process:

I have been involved in construction and finishing for 15 years. The last object can be considered a year or two! The fact is that the customer decided to use 16 mm DSP instead of plasterboard for internal partitions, and decided to cover the facade with it. We didn’t have any lift; we fixed it manually. Perhaps the material will justify itself, but it is very difficult to install. Victor. Ryazan.

As soon as I started cutting the DSP for the partition I immediately realized what I had done terrible mistake. I cut it with a grinder with a diamond blade, there was no dust except in the next block! There is no longer any desire to cut DSP panels indoors. Alexei. Novosibirsk

In the case of facade cladding, there are practically no negative reviews:

The outside of the house is covered with DSP panels and painted, with a layer of polyethylene and mineral wool laid underneath. The house has been dry and warm for two years, there are no fly agarics, cracks or mold outside, we are very happy. Karina. Volgograd region.

Cladding the garage with DSP slabs did not cause me any difficulties. I used the 12 mm version and a wooden frame made of pine beams 50x50 mm. I watched horror stories about possible cracks due to thermal expansion and decided to leave decorative seams, well, it seems like that’s what was intended. I painted it with façade paint and for the third year now there have been no problems. Yuri. Smolensk region.

Having carefully analyzed the performance properties of DSP panels and consumer reviews, the following conclusions can be drawn:

• The material is quite budget-friendly;
• The price/quality ratio is acceptable;
• Simple installation technology allows for independent installation;
• Inconveniences during installation are due to the high specific gravity of the material;
• When cutting there is high dust content.

In general, DSP boards are in demand for both interior, exterior and landscape work.
