Being a universal building material, cement- particle board successfully used in modern construction when carrying out internal and external work. The products contain natural wood, but are in many ways superior to other analogues (chipboard, OSB), since they positive properties does not end with excellent sound and heat insulation. DSP sheets have high strength, fire resistance and the absence of shrinkage processes.
The production of CBPB consists of the following stages:
The smooth surface of the slab is obtained due to the special distribution of chips in its structure - larger fragments are located inside the product, and small ones are on the surface. During the production of CBPBs, there are no voids in them. Another advantage is that the product is not subject to additional leveling, but can be immediately used to make a subfloor and serve as a high-quality, flat base for laminate, tiles and other types of finishing coating.
To understand what it is cement board, it is necessary to consider its composition. Cement particle board is a multicomponent sheet building material made from Portland cement and wood chips. In addition, the internal composition of the products is supplemented with special chemical additives to enhance the relationship between the main components. The proximity of cement and natural wood under normal conditions does not lead to positive results, since cement causes excessive moisture in the wood, its warping and rotting.
Additives are added to the composition of cement-bonded board to level out the negative effects of cement on wood; their amount is 2.5-3% of the total volume. In addition, they enhance the heat and fire resistance of the material. Due to the fact that cement predominates in the slab composition, it has high strength, frost resistance, soundproofing qualities, vapor permeability and biological passivity - it is of no interest to either insects or rodents.
Cement particle board, application which is absolutely safe, thanks to “pure” chemical additives, it is not afraid of the formation of fungus, exposure to moisture, and is not afraid of thermal shrinkage. And thanks to its high adhesion, DSP is compatible with many finishing materials.
Specifications
DSP plate, specifications and application which is possible in many areas, is produced at several enterprises in Russia, which allows them to maintain a single size range:
- The slabs can have a length of 2.7−3.2 m. Three-meter products are most in demand.
- The width size is strictly set at 1.25 m, which serves as the main guideline when installing sheathing for cladding surfaces of DSP boards.
- In terms of thickness, the most popular products are 10, 16 and 20 mm. In general, the thickness of cement bonded particle boards varies from 8 to 36 mm.
When choosing a material, it is worth considering that its thickness directly affects the weight of the product.
Pros and cons of the material
From positive qualities The DSP can be noted as follows:
Disadvantages of the material include heavy weight and significant dust formation when processing slabs. Cutting slabs should be carried out using tools personal protection- glasses and respirator.
Types of DSP
DSPs have several varieties:

Thermal properties
DSP, thanks organic compound wood and cement, are a homogeneous monolithic material without air inclusions, which ensures high thermal conductivity. Therefore, the greatest use of DSPs is found in structures where a combination of high strength and low temperature resistance of the material is required. Thermotechnical properties of DSP are assessed using the thermal conductivity coefficient, which is the most important thermal indicator of building materials.

Facades finished with DSP take on a stylish, modern look
DSP is a cement-bonded particle board. On English language sounds like “cement bonded particle board”. Refers to a variety of sheet composite material intended for use in the construction industry.
Characteristics of CBPB boards: sheet dimensions and price, thickness, weight
Thanks to the variety of technical indicators that meet modern requirements, cement-bonded particle boards seriously compete with common, flat slate and other sheet materials.
DSP board: technical characteristics, application
The main document that regulates the characteristics and use of CBPB boards is GOST 26816-2016. According to its provisions, two brands are distinguished - TsSP-1 and TsSP-2. They have some differences in the values of technical parameters.

The scope of application of cement bonded particle boards is quite extensive and includes several areas:
Weight of CBPB boards
Most often, the weight of building materials is estimated if a low-rise building is to be erected on its own. This indicator is directly proportional to the thickness and dimensions of the material.
If we consider a cement particle board with a length of 2700 mm and a width of 1250 mm, then the weight indicators depending on the thickness will have the following values.
With a length of 3200 mm and a width of 1250 mm, the weights will be as follows.
Note! Analyzing the indicators, it can be noted that with a thickness of 36 mm, the slabs become 4.5 times heavier than their eight-millimeter counterparts. Even 10 mm DSP has a fairly impressive weight, so it will be difficult for one person to work with such material.
Advantages and disadvantages of cement bonded particle boards
The popularity of DSP is based on a wide list of advantages of this material compared to analogues:
- Fire safety. Finishing made of cement-bonded particle boards does not support combustion. If a strong fire occurs nearby, they do not emit dangerous toxic elements.
- Multifunctionality. Possibility of using the material in different roles: partitions, finishing, creating a rough foundation.
- Biostability. Cement particle boards are not colonized by fungi. They are resistant to rodents and various bugs.
- Frost resistance. This characteristic becomes especially important when using the material in regions with harsh winters.
- Reliability. Even under conditions of frequent temperature fluctuations, the slabs do not undergo deformation for a long time.
- Noise insulation. The structure of the slabs allows you to protect living spaces from external sound influences.
- Moisture resistance. Even when used for finishing external facades, the material withstands atmospheric conditions well.
- Quick installation. If a private house is being built, then finishing it using DSP is carried out at a rapid pace, thanks to large area sheets.
Among the disadvantages is the high weight of the material, which makes it difficult to use on upper floors without special equipment. Another inconvenient factor is the abundant formation of dust during the process of sawing slabs.
What and how are CBPB boards made from?
The composition of cement bonded particle boards includes the following components:
- Portland cement −65%;
- wood shavings −24%;
- water −8.5%;
- additional impurities - 2.5%.
As a supplement, aluminum sulfate and liquid glass are used. It is necessary to pay attention to the product passport, which reflects these indicators. Also included is a certificate of certification and a quality passport.
The technological process consists of several stages:
- The chip component is mixed with hydration additives.
- Water and cement fraction are added.
- A slab is forming required sizes under pressure.
- It should be heated to 90 degrees and hardened under such conditions for eight hours.
The slabs are then aged to achieve their final hardness levels under natural conditions for two weeks. The last stage is grinding if it is provided for in the technological map.
Slab manufacturers have special equipment, conveyor lines, comply with GOST standards, and carry out the necessary quality control.
Main sheet sizes, prices and where to buy cement bonded particle board
GOST 26816-2016 regulates two standards for the length of CBPB: 3200 and 3600 mm. And also two width options: 1200 and 1250 mm. Among the range of different manufacturers, the most popular are products with a length of 2700 cm at standard width. Thickness values starting from 8 mm are graded in 2 mm increments. GOST reflects the possibility, if necessary, to order the manufacturer to produce slabs with other sizes.
The price of building materials also depends on the main dimensions. Below is an overview of the cost of the most popular types of cement-bonded particle boards.
With a length of 2700 cm and a width of 1250 cm, prices vary within the following limits depending on the thickness.
| Thickness, mm | 8 | 10 | 12 | 16 | 20 | 22 | 24 | 36 |
|---|---|---|---|---|---|---|---|---|
| price, rub. | 677− 703 | 816− 875 | 917− 987 | 1154− 1192 | 1421− 1440 | 1500− 1548 | 1560− 1580 | 1 605− 1700 |
The price for dimensions 3200x1250 mm is the following average values.
| Thickness, mm | 8 | 10 | 12 | 16 | 20 | 22 | 24 | 36 |
|---|---|---|---|---|---|---|---|---|
| price, rub. | 714− 738 | 838− 898 | 946− 1019 | 1166− 1178 | 1419− 1576 | 1608− 1634 | 2173− 2185 | 2193− 2198 |
Price for dimensions 3600x1200 mm.
| Thickness, mm | 8 | 10 | 12 | 16 | 20 | 22 | 24 | 36 |
|---|---|---|---|---|---|---|---|---|
| price, rub. | 755− 950 | 970− 1200 | 1150− 1250 | 1360− 1550 | 1365− 1600 | 1850− 2005 | 2350− 2650 | 2700− 2885 |
Based on average prices, you can calculate how much the modern material needed to carry out the planned work will cost. For example, the price of a 16 mm DSP board with a length of 3600 mm is 1500 rubles. To cover the facade, 35 slabs will be required. Therefore, you will have to spend 52,500 rubles on the purchase.
You can purchase cement particle board in stores specializing in the sale of building and finishing materials. Here you can get the necessary advice on choosing the right variety.
You can find many offers in online stores both from manufacturers and from representatives of companies producing this modern and popular material.
Handling rules - how to cut CBPB
Cement particle boards, which are superior in hardness, cause virtually no difficulties during processing. They drill and mill well. For example, to drill a hole, use screw drills, and the work is performed at high speed.
If it is necessary to cut CBPB, then at home they use different instruments. Be sure to wear safety glasses and a mask over your mouth and nose, as large amounts of dust are generated.
Expert's point of view
Dmitry Kholodok
Technical director of the repair and construction company "ILASSTROY"
Ask a Question"Can be used electric jigsaw, but you should select special files designed for cement. They are equipped with carbide tips.”
To reduce the amount of dust formation, it is recommended to irrigate the cutting area with water from time to time. You can remove dust immediately using a vacuum cleaner, which should be held by an assistant.For slabs thicker than 12 cm, it is advisable to use an electric disk tool.
Advice! Select discs that are designed for working on concrete, stone or brick. They are diamond coated. Preference is given to a circular saw, since when working with it, less dust is generated than from an angle grinder.
Scope of application of DSP in construction and repair
Considering the characteristics of DSP, its scope of application is quite extensive. When using, recommendations for selecting material thickness are taken into account.
DSP façade finishing
Facades finished with cement-bonded particle boards acquire a presentable appearance; the brick-look CSP coating looks especially attractive.
This building material does not require additional coating, reliably protecting the building from external influences. You can purchase cladding with the texture of stone, marble and other types of crumbs.
If the goal is insulation, then a material with a thickness of 8–16 mm is used, under which the insulation is first laid. Then the sheathing is formed and the facing slabs are fixed. Provides ventilation gap.
Application of DSP boards for flooring
DSP is becoming a popular material when laying floors. If you plan to directly lay the DSP on the floor along the joists, the thickness of the material is selected in the range from 20 to 26 mm. This provides good strength with an average lag pitch of 0.6 meters.
The result is a smooth rough base, ready for finishing. Self-tapping screws are used as fasteners.
Often, 12mm DSPs are used to level a floor structure whose structure is multilayer. In such a situation, logs, waterproofing, and plank covering are laid on the subfloor. The next layer is DSP, providing not only a flat floor surface, but also sound insulation.
If you use DSP with a decorative front layer, you can immediately get a clean floor without the need to lay other materials on top. This material is also used for installation. When constructing utility and storage buildings, laying slabs with a thickness of 24-26 mm is allowed directly on leveled bulk soil.
Production of SIP panels from DSP
An improved version of the new generation of building materials are SIP panels, the basis of the design is DSP.IN production process a sandwich is formed, for which insulation is placed between two cement-bonded particle boards, fixed under high pressure using glue.
The resulting structure is highly durable and does not require installation after installation. additional operations for building insulation. Using quality species heat-insulating layers of SIP panels differ environmental safety and fire resistance.
Article
Wood processing technologies have been gaining momentum recently. That is why today boards based on shavings, sawdust, and laminated materials, which are used in furniture production, are used everywhere.
Description and features
CSP - cement particle board, which has a sufficient level of strength. This allows them to be used in construction matters frame houses, where they are used on floors and walls. If somewhere such boards can be replaced with chipboard, OSB and others, then DSP will be especially relevant where humidity is high, for example, in a bathroom, toilet, furnace room. For the same reason, they can even be used for finishing facades, as well as as a roofing base before laying a soft roof.
Cement particle boards
Speaking about the features, it is worth analyzing the structure of this material. The main thing that gives the slab grey colour, is cement. According to GOST, its mass fraction must be at least 65%. At the production stage, gypsum is added to it, as well as additives that increase plasticity.
The second component is considered to be shavings. Its mass fraction is at least 24 percent. The remainder includes water, as well as binding additives. Water, after reacting with cement and additives, evaporates, leaving space with air. This results in the slab becoming lighter and warmer.
Types on sale
Like any types of building materials, CBPBs have a number of varieties. Their subtleties relate to the production aspect, since these plates look different, are used in different industries, and have unique features.
The first option is fiberboard. The base used here is not wood shavings, but fibers, which makes the base viscous and especially tensile. To achieve additional strength, liquid glass and calcium chloride are used at the production stage.
Thanks to their resistance to damage, the products are not only able to withstand heavy loads, but also resist the effects of sound. That is why fiberboard is often used as sound insulation in studios, shopping centers, bars, and discos. Despite these properties, fiberboard is easy to process yourself. To do this you do not need to have any special tool. It is easy to process even at home.
1. . This is the second version of the variety. Here sawdust is used as a wood binder. As production basis They use rice straw and reeds. Among all the raw materials used for production, wood chips provide the highest strength.
The performance characteristics here are lower than those of the above option, but the cost of such a product is also cheaper. As for the total weight, the sheets are heavier, but suitable for walls. That is why they are used to decorate low-rise frame houses of private construction.
Production of CBPB boards
2. Xylolite. This is the third variety. The strength of such products is so high that they can be used for both floors and walls. Lumber, namely wood chips, is used as the basis for production. On sale you can find not only the colors of the standard segment, but also various shades, which turns out to be quite profitable in terms of finishing. Sometimes they are even left without additional cladding, because the background general interior they look interesting and expensive.
Characteristics and dimensions
Characteristics of CBPB boards important at the selection stage:
- The weight of one cubic meter is about one and a half tons. It is important to take this into account when transporting when purchasing large volumes of slabs. Loading of packages is carried out using a manipulator. It can be used to organize delivery and unloading. As for the weight of one slab, it is small and installation can be done manually.
- Humidity up to 12%. This criterion corresponds to the state standard. Low humidity indicates that the stove does not absorb water even during operation. Therefore, it is supplied from the factory with a humidity of 9%, but even if it is used in rooms with increased level humidity, such as bathrooms, the material will not deteriorate at all even after a while. This implies another characteristic, such as water absorption in maximum quantities, which amounts to no more than 16% in one day.
- Sufficient thermal conductivity. Thanks to high density wood shavings, thermal conductivity is fixed at 0.26 watts per square meter. This is enough to use such material in frame houses. Vapor permeability is 0.03.
- The material can withstand bending pressure up to 9 megapascals. As for the compression pressure, this value is 0.4 megapascal. Flammability is equivalent to class G1.
The technological feature of production allows us to produce slabs of different thicknesses on the market. Basically, they are fixed values from 0.5 centimeters to 4 cm, inclusive. The width may also vary. It is fixed at 120 and 125 cm, respectively.
Dimensions of CBPB boards
As for the length, this value is fixed at 270 and 320 cm, respectively. State standard production assumes deviations in the thickness, width and length of the material up to one and a half mm, inclusive.
Application area
Regarding the scope of application, it is necessary to highlight the sphere of private and capital construction. A private developer can use this material everywhere, starting with finishing floor surfaces and finishing with wall decoration. DSP slabs for flooring have found their application.
They are able to withstand heavy loads and are easily processed using special paints. They do not disturb the interior to some extent; on the contrary, they give it a finished look. The main thing is to carry out the installation correctly, since if the technological process is violated, there is a possibility of losing the aesthetic appearance, as well as reducing the service life of the slab.
As for other areas of application, they are used for arranging the foundation. This is the so-called permanent formwork, with which the frame is made. The slabs are cheap, so it is convenient to use them here and leave them for later use.
They will be easy to finish on the outside, which will not disrupt any aesthetics in the long run. appearance Houses. Frame technology also assumes application of CBPB boards as a basis for future walls and ceilings. I also use DSP boards for the partitions to construct the frame.
DSP is used in the construction of frame houses
Today they are used in homes frame type, and where they are used to hem ceilings, and they can also be used for roofing structures with subsequent finishing soft material. Such slabs are hemmed reverse side stairs, sewing up communication niches, making blind areas and paths in the garden, and installing subfloors.
The most important thing to know Dimensions of CBPB boards. For the ceiling, for example, the thinnest material is suitable, since it will fulfill its task of arranging the base even with the smallest thickness. Otherwise, the floor needs a thicker base, since its resistance to loads should be maximum. The same can be applied to formwork.
How to install correctly and what tools are needed?
Installation of DSP boards can be done by hand. It’s not difficult, the main thing is to follow the basic rules of work. As for the basic rules, we suggest considering installation using the example of arranging the facade of a private house. Here you need to follow the following steps:
1. The foundation needs to be established. These are a kind of bars measuring 50 by 50 mm, which must be fixed to the load-bearing wall. If we have a frame house in front of us, then we can use the existing frame without additional modification.
Since the plate itself weighs a lot, it is not recommended to use a smaller cross-section, unless you can replace it with metal, 50 by 20 mm. The step between two adjacent beams should be no more than 60 cm. Vertical sheathing is performed with the specified step.
2. The insulation is being laid. For this reason, we previously chose a cross-sectional area of 50 by 50 mm. This is convenient for laying insulation with an overlap of 2 and 2 cm, respectively. The overlap is done in order to remove cold bridges at the junction of two plates.
Depending on the original base, the insulation is nailed either with special dowels or fixed to wooden profile through further installation wind protection membranes. The membrane is nailed to the tree using a stapler. One cm of space left between the insulation and the DSP board is a ventilation gap. It must be left during installation.
3. Installation of sheets. It is advisable to lay the first sheet perfectly level in order to limit the overall horizon for subsequent installation. The sheets are screwed using a regular wood or metal screw, depending on the base.
Before screwing the sheet, level it, fix it and make markings for further installation. Manufacturers recommend drilling holes for screws. To do this, use a drill of a smaller diameter. If you are not going to drill, then buy self-tapping screws with a drill.
Fasteners must be galvanized or pre-treated special compounds. It is impossible for two adjacent slabs to fit perfectly against each other. It is important to leave a ventilation gap, which can be up to 0.5 centimeters inclusive.
4. Don’t worry if parts of such a slab break off somewhere. In the future, you can always cover the walls with another material, but even small chips will not harm the overall integrity of the surface. The easiest way to further finish is to paint the surface.
Frame house sheathed with DSP
There are special paints for CBPB, which will give your home a sophisticated look. The paints are produced on the basis of acrylic or silicone, which makes them moisture resistant and allows them to maintain their saturation at critically low and high temperatures.
As for the tool, we need:
- A screwdriver, a drill with a drill whose diameter is smaller than the diameter of the screw.
- Level, wood saw, measuring tape, marking pencil.
Price
Price of CBPB slabs different. It is determined by the plant and the direct supplier. But, if we consider the middle segment of the market, then for an 8-meter particle board, it is quite possible to pay from 700 rubles. per sheet. We already talked about sizes earlier. So, the average sheet area is almost 3.83 square meters.
If you compare this price with OSB sheets, then for a similar square footage we can pay more than 1000 rubles. Therefore, particle board is more profitable than other finishing materials.
Otherwise, decide on the thickness and remember that the larger it is, the more expensive the cost of one sheet will be. For example, a similar sheet, but with a thickness of 12 mm, can be found on sale at a cost of 1,100 rubles.
Advantages and disadvantages
Advantages and disadvantages are important at the time of choice. They are worth considering, but you need to familiarize yourself with them first. Let's start with the advantages:
- Wide range of applications. This makes them multifunctional, since today sheets can be used for interior and exterior work. You have previously become acquainted with the scope of application and understand that they cover the entire range of construction of private and permanent houses.
- Covers a large area. By cutting just a couple of sheets, you can easily finish a fairly large area, about 8 square meters. The material is easy to process, so even if you do not have a specialized tool, you can always cut it into the necessary parts manually.
- The manufacturing process is quite complex, but no toxic harmful substances are used here. There is cement, wood, special glue, water and plasticizers. You can see for yourself that the material does not in any way spoil the surrounding atmosphere, does not violate the internal aesthetics of the premises and does not in any way affect people’s health from a negative point of view.
- Can be finished modern materials. This can be not only wood and wallpaper, but also paint, which is important for a material with a similar structure. Its high noise insulation properties make it possible to maintain comfort in homes, as well as hide particularly noisy objects from strangers.
Today on sale there is not only gray DSP board, but also those that were originally finished as brick, ceramic tiles and other finishing options. All this makes it possible to inexpensively veneer own house, bathhouse, garage and other buildings.
There are practically no disadvantages. Unless this includes big weight of CBPB board. This involves deepening the foundation, since the load on it will be large. During the installation process, it is necessary that the fasteners be galvanized or processed in a special way. Therefore, think about this moment in advance.
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%;
- shavings coniferous species trees – 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 quality characteristics 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. Maximum swelling allowed DSP sheets 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. It does not require additional surface treatment, which has a positive effect on the final cost of the products.
Where are DSP panels used?
Material made from cement and wood chips is a high-strength construction base with good 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 plates in the device permanent formwork, fencing, facade finishing. This greatly reduces work time, provides structures with the necessary reliability and saves overall construction costs.
Excellent performance characteristics make it possible to use slabs for floors, walls and ceilings in wet rooms, for example, a bathroom or bathhouse.
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 reserve 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 working professionally for many years construction work of varying complexity. 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. It is also convenient to mount it on the frame 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.
"First experience use of DSP I purchased it while refurbishment of the garage. It turned out that the slabs were not at all difficult to cut and attach. Finished walls painted 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 the 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 we decided to replace it a natural stone 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 costs in advance and it turned out 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 and welded them to them metal profiles 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.
