What is DSP
The uniqueness of the sheet of building material, which has received the short name of DSPs (cement-bonded plate), is that in its composition succeeded in combining seemingly incompatible components - Portland cement and crushed wood chips. This was possible due to the introduction of specific hydration additives, neutralizing the detrimental effect of components forming part of the plates on each other. Modern manufacturers have learned to make the plate without the use of harmful to human health of phenol and formaldehyde.
Technically manufacturing slabs process is as follows:
- The raw mass is formed in a special drum, where the wood chips are added sequentially, mineral components, Portland cement and water.
- Forming plate occurs in layers, wherein the finely grinded chips located outside, but a larger - inside the product, thus ensuring its durability. The smoothness of the top layer is achieved due to swarf.
- Moving along a conveyor line, billet reaches the hydraulic press, which under high pressure it is subjected to forming.
CFB sheet size, thickness, weight and price
High performance and applications DSP boards, this material was isolated among others. Novelty became increasingly used as thermal insulation materialFor interior device partitions, Sub-floor or nonremovable formwork. DSP and a decorative face layer, simulating stone or brickworkApply for facade.
Perfectly smooth surface allows uniform color or grout walls. If oblitsevat house panels and paint them in one of the pastel colors, you get a classic facade style half-timbered, Where the main role will be played by decorative strips covering the connecting seams between the panels.
Water-repellent products made on the basis of chip and cement indispensable for finishing wet rooms.
Specifications, the use of plates DSPs
DSPs have proved as durable material in the entire service life of preserving their quality. Finished products must meet the following criteria:
- product density should be from 1100 to 1400 kg / m³ under normal humidity conditions.
- Water uptake should not exceed 16%.
- It is allowed change in linear dimensions at high humidity (6-12%) in width of not more than 2% by length - 0.3%.
- Flexural strength shall be 12 MPa - thick for panels 10, 12 and 16 mm, 10 MPa - for slabs 24 mm thick and 9 MPa - for slabs 36 mm.
- Plate Tensile perpendicular tensile loads applied should be not less than 0.4 MPa.
- Sound-proof properties are 45 dB.
- Thermal conductivity - 0.26 W / m × ° C.
- According to GOST 7016-82 roughness value level indicator after grinding factory should not exceed 80 microns. For rough slabs, the figure is 320 microns.
- Material refers to a group readily flammable products (G1).
- For dry rooms service life of 50 years or more.
Basic dimensions and price lists
The width and length of the products may be allowable state standard deviations, and the plate thickness is greater, the greater the index value may be speaking of increasing or reducing the manufacturing parameters.

Pros and cons of applying a cement-bonded particleboards
DSP has the following positive features:
- Frost.
- fireproof.
- Moisture resistance.
- Sound- and heat-insulating properties.
- Biological passivity - the material does not rot, does not grow moldy.
- Resistance to deformation, it can be used for wall panel frame.
- Compatibility with polymeric materials, metal, wood.
- Panels lend themselves to cutting, drilling and sawing.
- Technologically simple installation plates that provides cost savings during construction.
- The versatility of the material associated with a variety of ways to finish - wallpaper, plaster, paint. They are perfectly fixed on a perfectly flat surface.
A significant drawback is the large weight of products, and therefore, delivery to the upper floors of buildings is carried out by means of lifting mechanisms. Another issue is related to the duration of service life - in direct contact with the environment, he is about 15 years.
Installation work - the cut DSP
Do not try to cut it with a hacksaw DSP - it is a thankless, long process, and the result leaves much to be desired. Or you can take advantage of jigsaw Bulgarian.

Important! Use recommended cutting discs with tverdosplavym coated concrete and stone, designed for this type of work. The tool is not quickly broke down, the speed should be at least 200 revolutions per minute.
Work Bulgarian associated with the formation of a large amount of dust. This can be avoided by means of the vacuum cleaner, connected to the device. However, not everyone knows how to do it. This was a small step by step guide:
| Photo | Description of work |
 | For work required removal at 45 ° sewer pipe 50 of diameter and a coil-reinforced dense masking tape. |
 | It is important to correctly position the nozzle. It is necessary not just to primotat grinder and plunge into the disc to half the pipe diameter. |
 | You must correctly identify the location of the nozzle - its lower edge should be no more than grinders lower body. |
 | With reinforced adhesive tape tube is securely fixed in a predetermined position. |
 | The open part of the housing carefully sealed with thick masking tape in several layers. |
 | When cutting disk is immersed in a material of the pipe - this can significantly reduce the level of dust. The very process of cutting by a motor forward. |
Important! In operation, the circulating saw dust formed smaller.
If you want to cut off a small section, or the hand is not a vacuum cleaner, is to reduce the formation of dust incision moistened with water.
Areas of application of DSPs
DSPs are widely used in many areas of the building due to its technical characteristics. Current products on the basis of cement and wood chips worthy of competing with plasterboard, Fibreboard and plywood.
The façade DSP
Home facades are faced with DSP, acquire aesthetic appearance. Facing layer of such articles may have a different design. They imitate other finishing materials (stone, masonry, plaster) Or have a textured decorative surface made of stone chips of different color and fraction.

The use of DSP for sex
When placing the floor DSP on logs, products recommended to choose a thickness of 24 mm to ensure sufficient strength of the flooring.
When working indoors is necessary to make preparatory activities - at the bottom of the hole to close up if they are to fix the lag, put heater and vapor barrier material.
Fixation plates made by means of screws, wherein a screw with countersunk head must be immersed in the body of wooden joists 20 mm. The result is a perfectly flat subfloor with excellent performance.

frame construction
DSP proven themselves in the construction of frame-type houses. There are two options - the purchase of finished domokomplekta SIP panels DSP or through a separate erection of walls, between which the mineral insulant. Fixation plates produced by metal or wooden crate, wherein the sewn perimeter frame, and thereafter cut window and doorways. Lath elements set in increments of 60 cm, so that between them can be firmly fixed heating material. Plates taken 10-16 mm thick, fixed them with galvanized screws.

Interior finishing work
Environmental safety of cement-bonded plates has made it possible to use them as a full fabric indoors for any purpose. Due to the high water resistance, this material is substantially pressed gypsum plasterboardWhich is not recommended for use on walls in wet areas.
DSPs are used for effective smoothing of walls and their subsequent finishing decorative surfacing materials. However, the DSP in some interiors (loft, Industrial, high tech and others), where appropriate untreated concrete texture, is used to create accent surfaces and even for covering entire rooms.
Mounting plates depends on the thickness and size of sheets, and, respectively, and their weight. Heavy products attached on the crate, and light - with a special mortar or mastic.
Manufacture of CIP panels DSPs
CIP panels DSPs are three-layer material where insulation from expanded polystyrene, basalt fibers or polyurethane (PUR) is fixed between the sheets.
Common feature of the material is its high fire and environmental safety. The ability to quickly build a private house, and significant savings on the facade finishing works.
The use of DSP for formwork in concrete construction
There are several advantages of permanent formwork device of this type in the production of monolithic works:
- Reduction of installation work and total construction time.
- Readiness surface for final finishing.
- High profitability of the facility as a whole.
- Guaranteed to provide a sound and reliable construction.
Installation and finish DSP
Cement particle boards require accurate and careful treatment during transportation, storage and installation. Due to the weight and dimensions of products are easily damaged.

"Particular attention should be paid to proper storage plates - they are placed horizontally, and to reduce pressure on the lower plate, at regular intervals packs pave bars. When transporting the product put on edge. "
Before anchor sheet, there pre-drilled holes required amount. When the vertical wall covering must take into account the thickness of the sheet and its weight.
The smooth surface of products allows you to create high-quality surface finish when the exterior or interior applications. Often, acrylic or silicone paint is chosen as a finishing material. On the construction site boards come in standard gray color, at the place of processed white primer and painted in the desired color.
Since the joints are not zashpaklovyvayut, for their camouflage is the most best one sealant that expands and contracts under the influence of the manifestations of the external environment.
