Sheet building materials are used in many types of construction work, which are commonly called "dry". One of these materials is the DSP board. It is a durable material that can be used in construction frame houses and outbuildings, for indoor and outdoor finishing works.
What is a DSP board
Cement- particle board(DSP) - foliage building material that is made from high quality cement (Portland cement) mixed with a thin long wood chips(according to GOST 26816 chips thickness 0.2-0.3 mm, length from 10 mm to 30 mm). Aluminum sulfate and liquid glass are added to the composition. When kneading, water is added (about 8% of the total mass). The resulting substance is molded in the form of plates, pressed.
DSP plate - sheet building material for interior and exterior work
Some manufacturers of DSP boards are made from several layers. They separately knead compositions with smaller and larger chips. A mixture with large chips is used for the inner layers, giving greater strength. Outer layers are formed from the composition with finer chips, which makes its surface smoother. The folded "pie" enters the press, as a result, a monolithic slab DSP with improved performance.
It is also worth mentioning that there are polished and unpolished DSP boards. Sanded can be used for internal or exterior finish in those works, after which finishing work can immediately follow. There are also finishing slabs of DSP, on one of the surfaces of which a finishing layer is formed in the form of a stone or brickwork, decorative plaster, etc.
Application area
DSP is mainly used in dry mounting technologies. They are good for the construction of frame houses, as they do not emit harmful substances, have high strength, low combustibility, emit a small amount of smoke during a fire, do not spread fire. Having high mechanical strength, they increase the rigidity of frame structures. All this makes frame houses Sheathed with DSP, more secure and reliable.
Objects to use DSP
Sheet DSP can be used in the construction of the following facilities:
- Frame houses up to 3 floors inclusive.
- Industrial, office buildings.
- Hotel complexes.
- Kindergartens, schools.
- Medical institutions.
- Sport halls.
- Warehouses, hangars.
Disadvantage: DSP slab has a significant mass (several times heavier), which increases the requirements for the foundation. Solid weight also becomes a problem when climbing to the second floor - you need helpers and or lifting equipment (at least a winch). Another disadvantage of DSP is its low resistance to bending loads. This limits their scope - they are placed on the base, in places with a small bending load, or must be mounted vertically.
Weather resistance and high humidity, fungi and bacterial lesions, allows the use of cement chip sheets in the construction of outbuildings: sheds, garages, cellars.
For finishing exterior and interior works
Another area of application of cement particle boards is the leveling of floors and walls. Compared to other materials, the DSP board has the best soundproofing characteristics, is not affected by fungi, and is well tolerated by climatic influences. Therefore, they are often used to create ventilated facades.
For interior decoration DSP boards can be used for the following works:
- Soundproof and fireproof partitions and walls.
- Interior lining of premises for any purpose (residential and non-residential, including those with high humidity).
- Window sills.
- Draft floor.
- Ceilings.
The positive point is that there are cement-bonded particle boards, polished and unpolished. Polished have an absolutely smooth surface. When using them, you can only seal the seams and then paint, wallpaper, use other finishing methods.
Characteristics and properties
DSP plate - relatively new material, while not too widely used in private construction. All because not everyone understands how he behaves in the long run. To understand whether it is good or not for your purposes, you need to know about all the properties.
Density and Mass
Density of DSP is 1100-1400 kg/m³. High density gives frame structures an increased level of rigidity. If this material is used for interior decoration, such walls have sufficient load-bearing capacity to hold shelves, cabinets and other fairly heavy items.
The material is quite thick and heavy. One sheet with a height of 2700 mm - depending on the thickness - weighs from 37 kg to 164 kg. This makes the lining of the second floor and above inconvenient. This can be considered a disadvantage.
Thermal and moisture expansion
For construction, such a characteristic as linear expansion with changes in humidity and temperature is also important. For the DSP board, it is present, but it is small. When the plates are located one next to the other, it is recommended to leave a gap of 2-3 mm between them. When installing the second row (in height), the recommended gap is 8-10 mm.
- Normal humidity at the sale is 9% (±3%).
- Low water absorption allows the use of this type of material for exterior decoration, for wall cladding in rooms with high humidity. When in water for 24 hours, the limit of thickness increase is no more than 1.5%. That is, when wet, they almost do not change size.
What else is worth knowing: when immersed in water, the dimensions change slightly - 2% in thickness and 3% in length. If the material is made according to technology, then even with a long stay on the street under the open sky, it does not change for years.
Strength indicators and installation features
Cement particle boards do not tolerate bending deformations well, but have very high strength under longitudinal loads. Therefore, they are used for mounting on vertical surfaces. Manufacturers do not recommend putting them on logs, but when laying on a subfloor or a rough screed, the material behaves stably. Since the DSP plate is not afraid of water ingress, it can be laid on the floor in rooms with high humidity.
Elastic modulus:
- in compression and bending 2500 MPa;
- for tension - 3000 MPa;
- in shear - 1200 MPa.
If the DSP is mounted on a frame, a crate is required with a step of at least 60 cm. During installation, fasteners are installed in increments of 20 cm. We install self-tapping screws not only along the perimeter, but also along the intermediate rivers of the crate. In this case, tiles can be glued onto the DSP board (primer, after it dries, tiles can be laid without adhesive composition).
Fire and frost resistance
The DSP plate belongs to slow-burning materials; fire does not spread over the surface; toxic or harmful gases are not emitted during combustion. Fire resistance limit (ability to contain fire) - 50 min. This means that the material will break down after 50 minutes of exposure to fire.
High frost resistance - a decrease in strength after 50 freeze / thaw cycles is not more than 10%, which allows the material to be used for building houses even in the Far North. The service life of this material on the street is 50 years.
It is these properties that make DSP the preferred material in. The structure is more reliable in terms of fire safety.
Soundproofing properties
DSP slab has good soundproofing characteristics and can be used for sheathing exterior or internal walls:
- reduction in the level of airborne noise for a plate with a thickness of 10 mm - about 30 dB, for 12 mm - 31 dB;
- reduction of the level of impact noise when boards are laid on reinforced concrete floor- with a thickness of 20 mm is 16 dB, with a thickness of 24 mm - 17 dB;
When using additional intermediate layers, impact noise becomes quieter by another 9-10 dB. That is, frame walls sheathed with DSP boards retain enough sounds to keep the house quiet.
The best combination is a combination of cement particle board and mineral wool. Mineral wool also serves as a heater, because due to the uniformity of the CBPB it has a small thermal resistance (it is not a heat-insulating material).
Performance characteristics
DSP boards are characterized by high vapor permeability - 0.03 - 0.23 mg / (m h Pa). This is about the same level as natural wood. With the right selection of the wall sheathing cake, the humidity in the rooms will be regulated naturally.
In addition, the DSP board has a high resistance to decay. This happens due to the natural process of formation of calcium hydroxide, which is formed when cement is converted into concrete and alkalizes the material so that it becomes an unfavorable habitat for fungi, insects and putrefactive bacteria.
Dimensions and weight
When purchasing materials for construction and finishing works, such characteristics as the dimensions and weight of the material are important. DSP sheets are available in two sizes: with a width of 1250 mm, the length can be 2700 or 3200 mm. In this case, the thickness of the DSP plates can be 8, 10, 12, 16, 20, 24, 36 mm.
It is clear that the thicker the plate, the greater its mass. Approximate weight values are given in the table (for different manufacturers there may be deviations both in the direction of increase and in the direction of decrease in mass).
Weight of cement particle boards depending on dimensions and thickness
You may also need the following settings:
- area of one sheet:
- 1250*2700 - 3.375 m²;
- 1250*3200 - 4.0 m²;
- the weight of a cubic meter of CSP is 1300-1400 kg.
The DSP sheet is a homogeneous monolithic material without air inclusions, which explains the high thermal conductivity of the material. This must be taken into account when developing a warming pie. The material adheres well to wood, polymers and metal, so it is convenient for construction work.
Mounting methods
The DSP board can be fastened with nails or self-tapping screws. When mounted on a frame, the boards must be mounted strictly vertical.
Scope of cement-bonded particle boards in private construction
For fastening cement-bonded particle boards, you can use:
- Galvanized screw nails with a diameter of 2.5 mm. The length is selected depending on the thickness of the sheet and the entire cake. The pinched part of the nail must be at least twice the plate thickness, but not less than 10 nail diameters.
- Screw and self-tapping screws with pre-drilling holes for the heads. The length is chosen according to the same principle.
When installing DSP boards, it is necessary to strictly monitor the number and order of installation of fasteners: the material has a large mass, so fasteners must be installed at least recommended values. The distance between nails or self-tapping screws depends on the thickness of the plate and is indicated in the table.
Each sheet of cement-bonded particle board is fixed along the perimeter, retreating a certain distance from the edge of the sheet. The installation frequency along the long and short sides of the sheet is the same, but depends on the thickness of the material. In addition, there is also an intermediate mount - in the middle of the height. Here the frequency of installing screws or nails is two times less than along the perimeter.
Processing and finishing methods
Despite the fact that cement particle board is much stronger, it is processed with the same tools: a milling cutter, saw, electric jigsaw. The difference is that you need to use more durable files.
For drilling, the use of a drill with a hard tip is recommended. You can use both a manual and electric drill. Grinding this material is not recommended, since this work removes the top layer, which increases water absorption. But when docking, sometimes it becomes necessary to equalize the height. In this case, you can use grinding machines any type. The recommended sandpaper grit is #16-25.
Please note that in order for the seams between the plates not to crack, the seam must be at least 4 mm in the inner section, and not less than 8 mm in the outer section. The distance is large, it can be closed with special rails (usually used for exterior decoration) or with an elastic band or sealant.
As a finish, the DSP board can be painted or covered with plaster. When exterior finishing, the joints between the plates are often simply painted over, leaving them unsealed. Another option is to use an aluminum profile lining that emphasizes the seams. You can also close the seam with a strip.
For interior decoration, the seam is filled with a sealant, which, after drying, retains elasticity. After that, you can plaster. The second option is to lay a special elastic cord, on top of which elastic plaster is again applied.
The construction of modern buildings requires more and more perfect, versatile, high-quality and inexpensive materials. One of the latest developments in this direction is DSP, which can be conditionally called an improved version of chipboard.
Cement particle board as a building material
Cement particle board on the market building materials relatively recently, already appreciated by many developers. Thanks to its excellent performance, with its help dry installation of structures is carried out in buildings for various purposes.
DSPs are produced by pressing. Hardwood shavings (its share is 24%) are mineralized under the influence of special hydration additives (2.5%), after which Portland cement (65%) and water (8.5%) are added to it. As a result, a monolithic smooth slab comes out from under the press, consisting of several layers with large fractions inside and small fractions outside.
Types and characteristics
There are 3 types of DSP:
- fibrolite – thermal insulation material based on long-fiber shavings (“wood wool”). Soft, easy to process, resistant to biological factors;
- wood concrete- made from sawdust and small chips. It has a wide range of applications (thermal insulation, decoration, material for wall partitions, etc.);
- xylolite(slab and cast). It has high strength, thermal insulation qualities and a wide range of color solutions used as a floor covering.
Due to their water absorption, the plates increase in size, so a gap is required when installing between them.
Pros and cons of plates
The high popularity of DSPs is explained by their numerous advantages:
- if the installation was carried out in accordance with the requirements of the technology, the service life of the plates can reach 50 years. The research results showed that the material does not lose its useful properties even after repeated cycles of freezing and thawing. Also, the plates showed high resistance to moisture, fire and biological factors;
- multi-layer structure provides high strength characteristics of DSP in tension and compression, which allow you to strengthen frame structures with the help of plates;
- plates are often used as insulation, which is explained by their good heat and sound insulation qualities;
- material processing is not difficult. He easy to drill and cut, its flat surface is excellent for applying putty, plaster and adhesives, thanks to which the plates are successfully used in the design of premises;
- the exact dimensions of the slabs significantly speed up the installation process;
- the front side of the DSP can have not only a flat, but also a corrugated surface. This ensures a variety of interior design;
- ecological cleanliness;
- relatively low cost.
The disadvantages of cement-bonded particle boards are much less:
- heavy material weight(about 14.5 kg per square meter), which greatly complicates the process of its installation. This is due to the high density of the DSP (up to 1400 kg per cubic meter);
- low strength indicators bending, which sometimes leads to breakage of the plates.
Scope of application
These plates are used in large and private construction. They are used to build houses, utility rooms, use them indoors and outdoors, and even make furniture. The thinnest slabs (from 10 to 16 mm thick) are used for sheathing the internal and external walls of buildings for various purposes. For fastening, it is necessary to first make a crate of wood or a metal profile. In addition to aesthetic such a design can also fulfill thermal insulation purposes.. In this case, the space between the DSP and the wall is filled with insulation. This method is often used to modernize old buildings. Its advantages are simplicity and relative cheapness. Permissible gap between the plates - up to 1 cm. The joints are sealed, overlays are attached over them.
The same DSPs (up to 16 mm) also used for the manufacture of internal partitions. Due to their high moisture resistance characteristics, they are often installed in bathrooms and other similar premises. The plates are pre-primed, the surface and edges are treated with water-repellent materials. They are also used to produce balcony railings, trim for fire-resistant doors, etc.
From the best varieties DSP can even make furniture
From DSP from 12 to 24 mm perform fixed formwork of foundations in low-rise construction. The high strength of the plates prevents their deformation when pouring the solution. Another advantage of the design is its simplicity. If DSPs are painted or pasted over with a waterproof material, they can act as vertical waterproofing.
Window sills made of fiber cement boards fit perfectly into any interior. They have all the advantages of wood products, but at the same time they are much cheaper. The thickness of the boards used for the production of window sills is 24-36 mm. They are not subject to deformation, durable, monolithic and affordable.
When arranging floors cement-bonded particle boards successfully replace chipboard. If the floor is laid from the DSP along the logs, then the distance between them should be within 60 cm, and their cross section should be at least 5x8 cm. DSP from 16 to 36 mm in thickness can act as a base, underlying, leveling or finishing layer with a front finishing. In some cases, they are used instead of a cement screed, as well as in the construction of a prefabricated floor according to bulk soils(CSP plates for the floor 24-36 mm thick).
The basis for a soft roof can be made from DSP. In these works, 16-24 mm plates are used.
Mounting methods
DSP can be mounted different ways depending on the purpose for which they are used. When finishing or insulating buildings, they are attached to a crate made of a metal profile or wooden bars with self-tapping bolts or nails. The arrangement of fixed formwork also involves frame erection (given the large weight of the plates, it, like the crate when finishing the walls, must be strong enough). In addition, the slabs can be laid on logs (when installing the floor) or rafters (under the roofing). When interior decoration, they are also can be attached to the wall with mortar or mastic.
Release form and cost
DSP goes on sale in sheets packed in packs. Panel thickness varies from 8 to 36 mm. Dimensions can be (in mm): 2700x1250, 3200x1200, 3200x1250 and 3600x1200. The number of sheets in a pack depends on the dimensions.
The cost is set per square meter or per sheet. In the first case, it depends only on the thickness, in the second, on all panel parameters. The dimensions of the csp boards for walls are different from those used for the floor, but the price is about the same. Price square meter 8 mm DSP from different sellers starts from 150-250 rubles. The most massive plate (36 mm) will cost about 4-5 times more.
By their own useful properties(with the exception, perhaps, only of weight) DSP is in no way inferior to analogues made of wood and even surpasses them. And the versatility of the material combined with affordable price make it an almost ideal choice for construction and finishing work.
About the construction of a house from DSP for a month is described in this video:
DSP plate (cement particle board)- popular building and finishing material, consisting of wood chips, Portland cement, water and special additives that provide the necessary performance characteristics.
Plates are made by pressing. The result is strong sheets with smooth surfaces and ends, which can significantly save time during their installation. This is a non-combustible material, so it is recommended for widespread use in construction.
DSP is used:
- as lining of columns, internal and external wall cladding, front door cladding
- for the construction of moisture-resistant partitions and wall cladding of wet rooms
- as a front covering for floors, ceilings, window sills, creating the basis for roofing
- as fixed formwork for building foundations

Where to buy cement particle boards
DSP slabs can be purchased at our warehouse complexes in Moscow and the Moscow region. It is possible to order the delivery of the material with payment on the spot. It is possible to form prefabricated machines with
Not so long ago in the country (in the USSR since 1987) the production of DSP was launched. What is the use of cement particle boards in modern construction and what are they?
DSP is a sheet composite material, for the manufacture of which medium and thin wood chips (24%), Portland cement grade M500 (65%), special chemical additives (2.5%) are used to reduce the negative impact of wood extracts on cement, and water (8 .5%) (Picture 1). Plates are obtained by pressing at a temperature of 900°C for 8 hours. After that, the products are kept under natural conditions for 2 weeks.
The most famous domestic manufacturer is the Tambov plant Tamak. Plates are also produced by TsSP-Svir (St. Petersburg), the Kostroma CSP plant, Omsk Stropan, Tyumen Sibzhilstroy and Zavod building structures located in Sterlitamak.
Russian products meet the requirements of GOST 26816-86. It is divided into 2 brands: TsSP-1, TsSP-2. Less stringent requirements are allowed for sheets of the last grade than for TsSP-1.
Cement particle boards have:
- density of 1100-1400 kg / m³;
- high thermal conductivity - 1.15 kJ/kg*0°C;
- vapor permeability of 0.03 mg / m * h * Pa (“breathable” material);
- fire resistance - practically does not burn, with high temperatures does not emit toxic gases and vapors;
- water resistance;
- decay resistance;
- high sound insulation;
- durability: 50 years warranty for operation in building structures;
- high strength to longitudinal deformation;
- surface evenness.
But cement-bonded particle boards, whose technical characteristics are generally good, also have a number of disadvantages:
- high price;
- during processing, an incredible amount of dust is generated, as a result of which the use of dust extractors, goggles and respirators is simply necessary;
- heavy material: 1 m² weighs approximately 10 kg, which makes it difficult to lift it to the upper floors of buildings, and for structures using DSP, a reliable, strong frame of wooden beams with a section of at least 50x50 mm or rectangular pipes with a section of 50x20 mm;
- low bending strength;
- insufficient ease of processing: at the construction site they are cut with grinders and manual circular saws(Image 2.3) using a cutting tool with carbide inserts or diamond wheels, sheets can be drilled, but it is better to perform these operations in the factory.
Application areas of DSP
The versatility of the plates allows them to be used to solve various construction problems.
First of all, these are outdoor works: the construction of frame buildings, the decoration of the facades of residential buildings, warehouses and agricultural premises, the use as a basis for soft roof, fencing of balconies and loggias, use as a fixed formwork for the foundation.
Facade cladding (Picture 4) is carried out by fastening cement chipboards with nails, self-tapping screws, metal staples or screws to a frame made of wooden beams or a metal profile. The optimal step of the crate is 60 cm, it is preferable to mount the bars vertically; for small areas, horizontal installation can be used. Between the sheets leave gaps of 4-5 mm, which prevent their deformation when the air temperature changes. The gap filler is an elastic mastic or sealing gasket, which is covered from the outside with flashings purchased or made from scraps of DSP. The space between the wall and the slabs, depending on the purpose of the building, can be left empty or filled modern insulation, for residential buildings this is very important. After fastening, the sheets are primed and applied decorative plaster or just paint.
In the manufacture of the base for a soft roof, special attention should be paid to the waterproofing of the joints. Technologically, the process of manufacturing the base from DSP is similar to working with wood materials.
For fencing balconies and loggias, it is much more expedient to use cement-bonded particle boards than the used asbestos-cement sheets, because instead of fragile material, a strong and durable fence is being built.
DSP formwork (Picture 5) is increasingly being used in construction low-rise buildings. It provides:
- Reducing labor costs and terms of work due to the simplest installation of the structure, moreover, it does not need to be dismantled.
- Coloring outside DSP sheets with special paints provide vertical waterproofing of the foundation.
- The design provides additional strength to the fabricated foundation.
- Formwork retains its shape during pouring and curing of concrete.
The use of DSP for interior work
Due to total absence release of any harmful gases and vapors during operation, cement-bonded particle boards are recommended for interior decoration (Picture 6): they level the walls (attached either to the frame of the most rigid reinforced profile, or to a special mortar or mastic), form internal partitions, especially in conditions of high humidity (to increase the service life, such a partition should be treated with a water-repellent agent and painted with waterproof paint).
Floor device using DSP
DSP boards are also used for the floor (Picture 7), and their use is preferable to the use of chipboard (chipboard) or oriented strand board (OSB). Usually, the installation of DSP for the floor is carried out on logs having a section of 50x80 mm, in increments of 600 mm.
With the help of the CSP you can:
- make a base for the floor;
- form underlying or leveling layers;
- lay a warm and clean floor with a front covering;
- lay the floor directly on the ground.
The thickness of the DSP is:
- For interior walls - 8-12 mm.
- For installation of internal partitions - 8-20 mm.
- For flooring DSP on the floor - 16-26 mm.
- for formwork installation - 12-56 mm.
- For roofing and exterior wall decoration - 10-16 mm.
- For the installation of frame buildings - 10-40 mm.
Cement particle boards can be safely recommended for the above works. But it is necessary to use the products of a domestic manufacturer, and not to purchase Chinese DSPs. Using the products of hardworking Asians can lead to swelling of the plates, their chipping, the sheets themselves can be crooked, and the surface is uneven.
The DSP plate, the technical characteristics of which will be presented in the article, is used quite often today. It is distinguished by outstanding qualities that have made the material common in private and professional construction.
Characteristics of the DSP plate
Due to the fact that the described material has excellent characteristics, it has found its wide distribution in various areas of construction. Cement particle board is composed of wood shavings, Portland cement, special additives, the latter of which are able to provide excellent protective qualities. During the production process, all of the listed components are combined, and then mixed until a homogeneous mass is obtained. Then the composition is pressed.
Products are manufactured in accordance with GOST, which strictly regulate the composition. Thus, among the components should be 65% Portland cement, 24% wood chips, 8.5% water, and 2.5% impurities. The density is ensured by the presence of Portland cement in the composition, the same component guarantees the durability of the material. The production of plates is carried out on special equipment in a factory, as evidenced by a quality certificate, as well as a product passport. The composition of the plates contains natural wood, which ensures the environmental friendliness of the material. This indicates that the stove is completely harmless to humans.
Positive features of the DSP
DSP plate, the technical characteristics of which you need to know before purchasing, has great quality, which allows the use of this material in professional construction. Technological processes the production of plates is based on the mineralization and bonding of all components, therefore, the appearance of a radioactive background, the release of steam, dirt or dust can be completely excluded.
DSP slabs are actively used in the construction of strong and warm housing. Quite often this material is compared with others. The described plates are so strong that they win in this comparison. Their service life is much longer.
Additional advantages include excellent resistance to temperature extremes and frost, which meets the requirements for modern building materials.
The DSP plate, the technical characteristics of which are described in the article, has proven itself perfectly. These products perfectly cope with the influence of rodents, insects, as well as mold and fungus. The composition of the material does not contain phenol, asbestos, impurities and formaldehyde resins. These plates can be used for all types of finishes. The surface of the plates can be plastered, finished with plastic, painted, tiled, covered with various decorative materials, etc. It is easy to use this material, as it can be easily processed. It contains a large amount of chips, which makes the product look like natural wood, but these plates have high strength. DSPs can be used in the construction of partitions, which will have excellent soundproofing qualities. DSP walls will be able to provide sound absorption up to 30 dB.
Strength characteristics of DSP
DSP, whose technical characteristics differ from other alternative materials, have a high density. This is due to the fact that the chip pressing method is used in the production process. The inner layers of the product contain fibers that have a more impressive length. This guarantees the material excellent elasticity, smoothness, as well as high strength characteristics. The material has several layers, so it is able to deal with moisture. The special technology used in the production does not allow the product to delaminate. The slab will not break even if it is subjected to a mechanical force like bending. The material copes well with high loads, during operation it can be affected by a mechanical nature, which makes such plates so common and popular in construction.
DSP cost
DSP - a plate, the 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 can be called 1250x2700 mm. the cost of such a sheet will be equal to 675 rubles. This cost can be called very affordable, which makes such material so popular among analogues. Despite the fact that the cost of the plate is quite small, its quality remains excellent.
DSP dimensions
The DSP plate, the technical characteristics of which must be indicated in the quality certificate, must be examined by the consumer before purchase. It is important to consider the size range of these products. The plate can have a width of 1250 mm or 1200 mm. The latest standard is considered modern. But, despite this, slabs are still being produced. different sizes. The length can be equal to 2700 mm, while the thickness is equivalent to 8 mm. Such a product weighs 36 kg. If the thickness is increased to 10 mm, the weight will be 46 kg. Thickness of 12 mm increases the weight to 50 kg, and 16 mm to 74 kg. The 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 mass will be 54 kg, while a thickness of 12 mm gives a weight of 65 kg.
The standard size is 1200 mm. A plate with a length of 2700 mm can have a thickness of 8 mm and a weight of 35 kg. A plate thickness of 10 mm gives a mass of 44 kg. Among other things, the buyer can purchase a plate that has been made to certain dimensions. The length of the slab can be 3600 mm or 3000 mm. You should not look for products on sale, the edges of which have a semicircular shape, since such plates are not available. Also, products whose edges are thinner are not produced in the factory. After the plate is purchased, it will not need to be treated with an antiseptic, since the products are exposed to antiseptic effects at the factory.
Scope of DSP
DSP slab, the technical characteristics of which must be studied before making a purchase, is used today in housing construction. Products are able to provide internal protection from the cold. This material can be used when cladding walls made of concrete. Products are used in low-rise construction, as well as in the construction of special-purpose buildings. DSP is excellent for rooms whose conditions are different increased level humidity. After the plate is installed, its surface does not have to be treated. It will be enough just to cover the surface with a primer or a composition that has water-repellent characteristics. Buildings in which DSP is used are capable of undergoing serious operational loads.
Additional scope of products
The DSP slab, the technical characteristics, the application of which can be found in this article, is also used for fixed formwork equipment, which allows achieving excellent results. At the same time, some positive features, among them: reducing the period of construction work, reducing the amount of construction costs, as well as ensuring the reliability and strength of the future structure. The DSP plate, the technical characteristics, the use of which made the products popular, is also used today in the manufacture of window sills. At the same time, the latter are obtained 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.
