Properties and application of csp boards. Description and properties of csp csp board what is it used for

The construction of modern buildings requires increasingly advanced, versatile, high-quality and inexpensive materials. One of the latest developments in this direction is CBPB, which can roughly be called an improved version of particle boards.

Cement particle board as a building material

Cement- particle board, which appeared on the building materials market relatively recently, has already been appreciated by many developers. Thanks to its excellent performance characteristics, with its help, dry installation of structures is carried out in buildings for various purposes.

DSPs are manufactured using the pressing method. Hardwood shavings (its share is 24%) are mineralized under the influence of special hydration additives (2.5%), after which Portland cement (65%) and water (8.5%) are added to it. As a result, a monolithic smooth slab emerges from the press, consisting of several layers with large fractions on the inside and small ones on the outside.

Types and characteristics

There are 3 types of DSP:

• fiberboard – 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 shavings. It has a wide range of applications (thermal insulation, finishing, material for wall partitions, etc.);
• xylolite(slab and cast). It has high strength, thermal insulation properties and wide range color solutions, used as flooring.

Due to their water absorption, the slabs increase in size, so when installing, a gap is required between them

Pros and cons of slabs

The high popularity of DSPs is explained by their many advantages:

• if the installation was carried out in accordance with the technology requirements, The service life of the slabs can reach 50 years. Research results have shown that the material does not lose its beneficial properties even after repeated cycles of freezing and thawing. The boards also showed high resistance to moisture, fire and biological factors;
• multilayer structure provides high strength characteristics of the DSP for tension and compression, which allow you to strengthen frame structures using slabs;
• slabs are often used as insulation, which is explained by their good heat and sound insulation qualities;
• processing the material is not difficult. He easy to drill and cut, its flat surface is excellent for applying putty, plaster and adhesive compositions, due to which the slabs are successfully used in the design of premises;
• exact dimensions of the slabs significantly speed up the installation process;
• the front side of the DSP can have not only a flat, but also a corrugated surface. This ensures a variety of room design;
• ecological cleanliness;
• relatively low cost.

There are significantly fewer disadvantages of cement-bonded particle boards:

• heavy material weight(about 14.5 kg per square meter), which significantly complicates the installation process. This is explained by the high density of CBPB (up to 1400 kg per cubic meter);
• low strength indicators bending, which sometimes leads to breakage of the slabs.

Scope of application

These slabs are used in large and private construction. They are used to build houses, utility rooms, use them indoors and outdoors, and even make furniture. The thinnest slabs (from 10 to 16 mm thick) are used for cladding the internal and external walls of buildings for various purposes. For fastening it is necessary to first make a sheathing of wood or metal profile. In addition to aesthetic this design can also serve thermal insulation purposes. In this case, the space between the DSP and the wall is filled with insulation. This method often used to modernize old buildings. Its advantages are simplicity and relative low cost. The permissible gap between the plates is up to 1 cm. The joints are sealed and overlays are attached over them.
The same DSP (up to 16 mm) also used for making internal partitions . Due to their high moisture resistance characteristics, they are often installed in bathrooms and other similar rooms. The slabs are pre-primed, the surface and edges are treated with water-repellent materials. They are also used to produce balcony railings, cladding for fire-resistant doors, etc.

From the best varieties DSP can even make furniture

Installation methods

DSPs can be mounted different ways depending on the purposes for which they are used. When finishing or insulating buildings, they are attached to the sheathing, made of metal profiles or wooden blocks, with self-tapping bolts or nails. The installation of permanent formwork also involves erection of the frame (given the large weight of the slabs, it, like the sheathing when finishing the walls, must be strong enough). In addition, the slabs can be laid on joists (when installing the floor) or rafters (under roof covering). For interior decoration they are also can be attached to the wall with mortar or mastic.

Release form and cost

DSP is sold in sheets packaged in bundles. Panel thickness varies from 8 to 36 mm. Dimensions can be (in mm): 2700x1250, 3200x1200, 3200x1250 and 3600x1200. The number of sheets in a pack depends on the dimensions.
The cost is set per square meter or per sheet. In the first case, it depends only on the thickness, in the second - on all panel parameters. The sizes of CBPB slabs for walls differ from those used for floors, but the price is approximately the same. The price per square meter of 8 mm DSP from different sellers starts from 150-250 rubles. The most massive slab (36 mm) will cost about 4-5 times more.
In terms of its useful properties (except, perhaps, only for weight), DSP is in no way inferior to its wood counterparts and even surpasses them. And the versatility of the material, combined with an affordable price, makes it practically perfect choice for construction and finishing works.

The construction of a house from fiber board in a month is described in this video:

IN modern construction And finishing works The term DSP is often used. The abbreviation stands for cement bonded particle board, and it is one of the popular and high-quality building materials.

Thanks to innovative manufacturing technology, CBPB boards have unique characteristics that are noticeably higher than those of their wood-fiber counterparts, plasterboard and plywood. Let's consider the key advantages of this building material.

Main technical characteristics

Cement-bonded particle boards are made from crushed wood chips and cement, adding substances to the composition that completely eliminate the conflict of materials. The raw materials are laid one by one, forming a multi-layer sheet with special properties, which is formed by a hydraulic press.

As a result, DSPs have the following characteristics:

Sound insulation indicators - up to 45 dB.

Change standard sizes with prolonged exposure to a humid environment - no more than 0.3-2%.

Bending and tensile strength - 2,500-3,000 MPa, respectively.

Fire safety - class G1 (low-flammable materials).

The average service life is up to 50 years.

It is worth noting that DSP boards are resistant to temperature changes, are easy to process and are not susceptible to mold formation. Disadvantages include dependence on humidity environment: if the material is in contact with water for a long time, the service life is reduced to 15 years.

Is it burning or not?

The combustibility of a material is one of the key issues of interest to builders and finishers. Considering that the composition includes wood, cement particle boards can catch fire, however, this requires prolonged exposure to high temperatures.

When you are in a completely blazing house, the DSP needs contact the fire for at least an hour before it ignites. In addition, the material does not contain active chemical components, so even in the event of a fire, there is no risk of poisoning from combustion products.

Composition of the CBPB board

When producing cement-bonded particle boards, manufacturers are guided by GOST standards that are used for this type of building materials. In particular, the following ratio of components included in the finished product is used:

Crushed wood shavings - at least 30%.

1. Portland cement - no less than 58%.

   Additional impurities - 2.5%.

It should be clarified that the percentage of raw materials used must be indicated on the packaging. Here are the data recommended by GOST, which may differ slightly for the products of some manufacturers. However, when choosing a material, you need to focus on the given values: this is the key to the quality and strength of CBPB boards.

Application

Main area of ​​use of this material- this increases the thermal insulation properties and sound insulation of premises. Therefore, the material is often used in private residential buildings and in the construction of commercial and industrial facilities.

Cement particle boards are optimally suited for interior and exterior wall finishing, floor preparation finishing. In addition, the material is often used for arranging interior partitions.

Regardless of the scope of application, DSPs are guaranteed to withstand the service life declared by the manufacturer, which is about 50 years!

Standard sizes

As already mentioned, CBPB slabs are manufactured in strict accordance with GOST standards, and accordingly have strictly defined external parameters. If we talk about standards, the following sizes apply here:

Sheet length - 2,700/3,200/3,600 mm.

Width - 1,200-1,250 mm.

Thickness - 8-36 mm.

It is necessary to clarify that this data is relevant only for products from domestic manufacturers. The European construction market has different standards.

Sheet weight

In the table above, the data is shown in a separate column. The weight of the sheet directly depends on two fundamental factors: thickness and area of ​​the product. At the same time, the length and width of the sheet are usually standard; only the thickness changes, which largely determines the performance characteristics and scope of application. Let's look at weight change standard sheet(3,200*1,250 mm) depending on thickness. It looks like this:

Thickness 10 mm - weight 54 kg.

12 mm - 64.8 kg.

16 mm - 80 kg.

20 mm - 108 kg.

The weight of the densest sheets can reach up to 194 kg, however, such material is very inconvenient for independent work. For cladding walls and arranging interior partitions, sheets are usually used, thickness 16-20 mm.

How to cut this material

It’s worth clarifying right away that it is better to cut cement particle boards in production workshops: The work is very dusty and requires a special tool for an even cut. At home, you can use the following devices:

The working surface of the tool must be made of carbide materials, the rotation speed of circular saws is: no more than 200 rpm.

To minimize room contamination and reduce the amount of dust, it is recommended to spray the surface of the material being cut with water and prepare a vacuum cleaner to suck up fine particles.

List of verified manufacturers

On Russian market, there are several proven companies producing quality products that meet GOST standards. When choosing a DSP, you can pay attention to the following manufacturers:

JSC "TAMAK". The company is located in the Tambov region, producing cement-bonded particle boards in accordance with domestic and European standards (EN 634-2). The products are solid monolithic sheets without the slightest defects.

LLC "TsSP-Svir". The company operates in the Leningrad region, filling the market with quality products. Character traits finished sheets: sanded or calibrated surface light gray. The production uses German equipment, which ensures the production of CBPB boards according to Russian and European standards.

JSC "MIT". The company's production line is located in the Kostroma region. The finished sheets have a clear geometry, meet Russian quality standards, and are sold in an affordable price segment.

LLC "Stropan". The company operates in the Omsk region. The main characteristics of the finished sheets look like this: thickness from 10 to 36 mm while maintaining standard dimensions, elasticity of the material - 3,000 MPa, excellent thermal conductivity and sound insulation.

LLC "ZSK". The company is located in the city of Sterlitamak, Republic of Bashkortostan. The manufactured products have standard sizes corresponding to GOST, and are resistant to aggressive environmental influences and temperature changes.

It is important to clarify that everything Russian companies for the production of cement particle boards, they work on equipment from Western manufacturers. This helps to produce high-quality products at reasonable prices.

Useful to know during installation

It must be remembered that you need to work with cement particle boards very carefully: the large area of ​​the sheet makes it fragile, so installation is carried out by at least two people.

In addition, CBPB boards are not laid closely; expansion joints must remain. The material contains wood, which tends to expand under the influence of a humid environment. Given this feature, it is not recommended to fill joints with putty. It is better to use a sealant that will not interfere with the expansion of the DSP boards.

Not long ago, the country (in the USSR since 1987) launched the production of CBPB. How are cement particle boards used in modern construction and what do they represent?

DSP is a sheet composite material, for the manufacture of which medium and thin wood chips (24%) are used, Portland cement M500 (65%), special chemical additives (2.5%) to reduce negative impact wood extracts for cement, and water (8.5%) (Image 1). The slabs are produced by pressing at a temperature of 900°C for 8 hours. After this, the products are kept under natural conditions for 2 weeks.

The most famous domestic manufacturer is the Tamak plant in Tambov. Plates are also produced by TsSP-Svir (St. Petersburg), Kostroma TsSP Plant, Omsk Stropan, Tyumen Sibzhilstroy and Plant building structures, located in Sterlitamak.

Russian products meet the requirements of GOST 26816-86. It is divided into 2 brands: TsSP-1, TsSP-2. The latter grade of sheets is subject to less stringent requirements than TsSP-1.

Cement particle boards have:

• density 1100-1400 kg/m³;
• high specific 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;
• resistance to rotting;
• high sound insulation;
• durability: 50 years warranty for use in building structures;
• high strength to longitudinal deformation;
• surface evenness.

But cement particle boards, specifications which 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, safety glasses 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 made of wooden beams with a cross-section of at least 50x50 mm or rectangular pipes with a cross-section of 50x20 mm;
• low bending strength;
• insufficient ease of processing: at a construction site they are cut with grinders and hand-held circular saws (Image 2.3) using cutting tool with carbide plates or diamond wheels, the sheets can be drilled, but it is better to perform these operations in a factory setting.

Application areas of DSP

The versatility of the boards allows them to be used to solve various construction problems.

First of all, these are external works: construction of frame buildings, finishing of facades of residential buildings, warehouses and agricultural premises, use as a basis for soft roofing, fencing of balconies and loggias, use as permanent formwork for the foundation.

Facade cladding (Image 4) is carried out by attaching cement-bonded sheets using nails, self-tapping screws, metal brackets or screws to a frame made of wooden beams or a metal profile. The optimal lathing pitch is 60 cm; it is preferable to mount the beams vertically; for small areas, you can use horizontal installation. Gaps of 4-5 mm are left between the sheets, which prevent their deformation when the air temperature changes. The gaps are filled with elastic mastic or a sealing gasket, which is covered from the outside with purchased or made from chipboard scraps. Depending on the purpose of the building, the space between the wall and the slabs can be left empty, or it can be filled with modern insulation; this is very important for residential buildings. After fastening, the sheets are primed and decorative plaster is applied or simply painted.

When making a base for a soft roof, you should pay attention Special attention for waterproofing joints. Technologically, the process of manufacturing a base from DSP is similar to working with wood materials.

For fencing balconies and loggias, using cement particle boards is much more expedient than using asbestos-cement sheets, because instead of fragile material, a strong and durable fence is constructed.

DSP formwork (Image 5) is increasingly used in the construction of low-rise buildings. It provides:

1. Reducing labor costs and work completion times due to maximum easy installation structure, moreover, it does not need to be dismantled.
2. Coloring outside DSP sheets with special paints provide vertical waterproofing of the foundation.
3. The design provides additional strength to the manufactured foundation.
4. The formwork retains its shape when concrete is poured and hardened.

Application of DSP for interior work

Due to the complete lack of allocation of any harmful gases and vapors during operation, cement particle boards are recommended for interior decoration of premises (Image 6): they are used to level walls (either attached to a frame made of the most rigid reinforced profile, or to a special mortar or mastic), to form internal partitions, especially in conditions of high humidity (to increase service life, such a partition should be treated with a water-repellent agent and painted with water-resistant paint).

Floor installation using DSP

DSP boards are also used for flooring (Image 7), and their use is preferable to the use of chipboard (chipboard) or oriented strand board (OSB). Typically, the laying of DSP for flooring is carried out on logs having a cross-section of 50x80 mm, in increments of 600 mm.

With the help of DSP you can:

• make a base for the floor;
• form underlying or leveling layers;
• lay a warm and clean floor with a surface covering;
• lay the floor directly on the ground.

The thickness of the DSP is:

1. For finishing interior walls- 8-12 mm.
2. For installation of internal partitions - 8-20 mm.
3. For DSP flooring - 16-26 mm.
4. for installation of formwork - 12-56 mm.
5. For roofing works and external wall decoration - 10-16 mm.
6. For installation of frame buildings - 10-40 mm.

Cement particle boards can be safely recommended for performing the above work. But it is necessary to use products from a domestic manufacturer, and not to purchase Chinese chipboards. Using the products of hardworking Asians can lead to swelling of the slabs, their chipping, the sheets themselves may be crooked and the surface uneven.

Cement particle board (DSP) can be very useful in construction and repair, being used quite often for finishing and flooring of frame structures. Such material is a leader in many respects on the modern market.

He will become very a winning option when used in normal living rooms and public areas, but especially where the humidity level is constantly higher than normal: in bathrooms, showers, kitchens, swimming pools.

Such slabs can also be irreplaceable when arranging facades and paved paths; as a thermal and sound insulator; for the construction of window sills, canopies and other similar structures.

DSP board– a multicomponent material produced in a factory by pressing and subsequent fermentation. The components used in the composition are a mixture various materials:

• Portland cement is the main one, containing about 65% of the total volume;
• wood shavings are the second most important component (24%);
• During manufacturing, various minerals are also added as binders;
• other chemical ingredients and water.

This composite material ultimately takes the form of sheets of different sizes, corresponding to state standards. The resulting building element, which has been relevant for a number of decades, has quite a lot of positive properties. Let's list the most important of them.

1. Multifunctionality. The use of slabs is multifaceted: they are perfect for decorating rooms for various purposes; there are special slabs for flooring; DSP is widely used for the construction of internal partitions of rooms.

2. Environmental friendliness. The boards contain only safe substances. The release of harmful vapors and elements into the atmosphere during production is completely eliminated.

3. Big choice material parameters. Dimensions of the CBPB board are widely represented in the assortment. Modules of 3200x1250 mm are considered standard. But significant deviations are allowed depending on the thickness of the sheets, which can be from 8 mm and much higher. If the last parameter is large, it is also possible to change the length and width upward.

4. All products have a quality passport, certificates and comply with GOST. Therefore, when purchasing products from a large manufacturer, there is no doubt about their quality.

6. Durability. With external similarity to wooden structures, the material is more reliable. Therefore, most often, it is preferable to wood. This indicator is ensured by a three-layer structure. The outer layers, located on both sides, consist of small chips. The internal contents contain stronger formations.

Here you should also add the smoothness of the material, its resistance to moisture, ease of installation and affordable prices, the ability to operate in difficult conditions. A separate disadvantage can be considered the short service life in especially aggressive environment. But it is also about one and a half decades. However, by creating additional protection, it is possible to significantly extend the quality life of the material.

Kinds

There are three types of DSP. Studies of the material have accurately shown that each of them does not lose its valuable properties even during multiple cycles of significant temperature increases and subsequent defrosting.

Resistance to fire and particularly humid environments, as well as negative biological factors, was also confirmed. But each type of slab has its own characteristics, consisting in the production method, the difference in source materials, characteristics finished products and scope of application. Among the types you can indicate.

1. Fiberboard. Its basis is the so-called wood wool, which is long-fiber shavings. The composition also includes inorganic binders.

Wood strips produced on special machines are impregnated with solutions of calcium chloride and liquid glass. The raw materials are pressed into molds and subsequently dried. The thickness of such slabs can reach 150 mm, but there are a number of much thinner parameters.

These building elements, with their considerable strength, are excellent for thermal insulation. A similar material is also used as an acoustic material.

It is easy to process and soft, for this reason it is in demand for multifaceted repairs, as well as reconstruction work of various structures. During construction operations with slabs, due to their low weight, lifting equipment is not required, and therefore their use is very economical.

2. Wood concrete. It is classified as lightweight concrete and contains small shavings, sawdust, reed chaff or rice straw. The highest quality slabs of this variety are made from wood chips.

If the basis of the composition is wood shavings, then the material is usually called wood concrete, if sawdust - sawdust concrete. The two types mentioned have slightly reduced performance characteristics compared to the first one mentioned above.

They are heavier, denser and subject to unpleasant deformations, but they are also somewhat cheaper. The scope of application of wood concrete is quite wide. But mainly it is in demand as a material for low-rise private construction, especially popular in the manufacture of wall partitions, also for finishing and thermal insulation.

3. Xylolite is most often known in application as a coating. DSP for flooring. Plates, similar to those previously described, are made from wood waste, differing from other types in production technology. On sale, the presented assortment pleases with a variety of colors.

The material is distinguished by excellent thermal insulation qualities and increased strength. IN open fire does not burn, but only gradually chars; even when boiling, it does not get wet in water and is only slightly thermally conductive; It has enviable elasticity and is hard like stone, but at the same time it is easily processed like wood: drilled, planed and sawed. In addition to the above, it is ideal for use as cladding for stone, covering stairs, window sills, and roofs.

An important characteristic is weight of the CBPB board. Such indicators are simply necessary to know during construction and other work. The specified data is very useful during cargo transportation and during installation work. The mass of one module directly depends on the thickness and, knowing this indicator, it is easy to calculate. After all, for every 10 mm there is approximately 54 kg of tile weight.

Application

Using slabs to cover the floor is extremely convenient. To acquire an aesthetic appearance, there is no need for subsequent finishing. Their surface is easily treated with paint of a special composition.

It is also possible to use water-repellent dyes or regular ones. Such panels look advantageous against the backdrop of any interior, without disturbing the aesthetics, satisfying even the most picky and demanding taste.

Of course, excellent quality installed slabs there is a chance to enjoy it only after the best installation, carried out according to all the rules. If the modules are carelessly secured and poorly processed, this will significantly reduce not only the appearance of the overall structure, but also the service life DSP.

But use of slabs in the process of finishing the walls and floors of various rooms in the right way, it gives an excellent result as a result of practical use. In addition, if necessary, it provides almost perfect thermal insulation and a very durable coating.

Laying on the floor is done by screwing it to the sheathing using self-tapping screws with a countersunk head. During installation, everything depends on the material of the array. If it is steel, then the screws are screwed in by 10 mm, but if it is wood, they should go into the base of the beam by 20 mm.

It should be remembered that despite its remarkable properties, the basis of the material is wood. This means that the slabs, albeit slightly, have the ability to expand under the influence of moisture. Therefore, when finishing with DSP boards the presence of an expansion joint is often necessary. This is mandatory:

• next to walls, thresholds, columns and others vertical structures;
• if you plan to change the type and thickness of the floor;
• in case of a large coverage area.

These slabs play an important role in creating formwork. Moreover, in this and other cases, the choice of this particular material will entail many advantages: it will help to build reliable design, in a short time and with absolutely minimal costs.

In this case, additional cladding will not be required here, since the structure will already have a completely finished, certainly attractive appearance and high-quality characteristics. For the reasons listed above, such slabs are in great demand.

And when choosing the required thickness of the modules, it is better to obtain preliminary special consultation. It can be clarified that when finishing the floor, the optimal indicator ranges around 30 mm.

It is recommended to use special DSP slabs for facade. This material in this quality looks extremely advantageous in appearance. For best protection It is better to choose external coating modules of the maximum possible thickness.

This will protect general design structures, as well as the foundation, from negative external factors: strong winds, heavy rains and other things. Advantage of application DSP facade slabs is the possibility of further painting in any desired color, while the surface will appear as smooth as possible, which is very suitable for varied and original design solutions.

At the same time, the combination of contrasting colors looks extremely advantageous. color ranges so that the walls and roof of the house are of different colors, which will ensure a wonderful result.

They look especially attractive, even stylish, when used for finishing and creating an additional barrier of protection between internal elements buildings and external sphere DSP boards for brick or stone.

They differ from other types in their composition, built exclusively from the smallest particles of raw materials. Such sheets are in undoubted consumer demand.

Their convenience is that there is no need for subsequent processing with paints and other special compounds. That is, immediately after release they are ready for installation, and therefore are considered a popular finishing material.

Price

The low cost of the material does not affect its quality characteristics, which is ideal for solving many construction problems. Moreover, tile production technology is regularly improved and tries to adapt to complex and sophisticated consumer needs.

For example, the range has recently been updated with ultra-thin slabs, the thickness of which reaches 4 mm. The advantage of this type of product is that there is no need to use grinding machines to process such slabs, which undoubtedly affects the cost of the product offered.

A brand that is gaining particular fame in Lately, is "Tamak". The company produces finishing materials, causing great interest in the market. CSP boards are available in a variety of sheet sizes with thicknesses starting from 8 mm.

When choosing such a material, individual characteristics should become the object of close attention. Among the important indicators: size parameters, properties, composition. At normal humidity, according to existing standards:

• the slab should swell by less than 2% of the total volume of the material;
• the ability to absorb water cannot exceed 16%;
• density should not be more than 1300 kg/m2;
• The roughness of the panel for plates processed by grinding must be 80 microns.

Retail prices of CBPB boards are invariably dependent on leaf sizes. Average material cost:

• with a thickness of 10 mm it averages about 950 rubles;
• if the thickness is doubled – 1,700 rubles;
• three times - from 2000 rudders and above.

When purchasing material, it should be borne in mind that prices for wholesale buyers are undoubtedly significantly reduced.

When planning to build a large private house several floors high, it is better to choose the thickest possible slabs when purchasing in order to subsequently achieve stability and strength in the structure.

Of course, such sheets will cost much more. As a rule, slabs that go on sale come in the most simple colors, intended for further coloring, according to the choice of the desired shade.

But from an aesthetic point of view, it is better to choose samples with decorative coating, paint adheres better to them, and color options are purely individual and have no repetitions.

The modern market provides enough slab products. However, DSP boards are recommended by experts as among the best, having wide application at any stage of construction. At the same time, only rare ones can compete with them in quality Construction Materials.

Thermal properties

DSP, thanks to the organic compound of wood and cement, is 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. The thermal properties of DSP are assessed using the thermal conductivity coefficient, which is the most important thermal indicator of building materials.

Impact noise insulation index

Cement particle boards with a thickness of 20 and 24 mm, laid directly on the reinforced concrete load-bearing floor of the measuring chamber of the NIISF RAASN, provide improved impact noise insulation by 16-17 dB, respectively.

When laying cement particle boards with a thickness of 20 and 24 mm not directly on a reinforced concrete floor slab, but elastically on the intermediate layer soft material There is an additional improvement in impact noise insulation, amounting to 9-10 dB.
