Mineral wool slabs of increased rigidity or PPZH 200 from the Rockwool brand are designed to insulate structures that are exposed to severe stress. They are made from durable mineral raw materials with the addition of binders. Before working with insulation, it is important to study in advance its technical characteristics, pros and cons, as well as the available areas of its application.
Description of insulation Rockwool PPZh 200
Insulation Rockwool PPZh 200 is a mineral wool slab made with basalt fibers. It is a non-flammable, hydrophobic and vapor-permeable material with a dense fibrous structure. Boards of this type are impregnated with a synthetic binder, which ensures their maximum strength. Due to their structure, they have a low level of thermal conductivity, which makes it possible to use them as a heat insulator. In this case, the temperature of the insulated surfaces can reach 200 degrees.
Plates from the manufacturer Rockwool are made from phenol-free environmentally friendly raw materials. They have a Hygienic Certificate, which makes it possible to use them in the field of civil engineering, as well as a radiation safety certificate. The thickness of the slabs can vary from 50 to 100 mm with a step distance of 10 mm. All materials of this type are produced with the addition of water-repellent additives that prevent the development of fungi and mold.
Specifications
Plates ППЖ 200 belong to the low-combustible group of materials of category G1 and difficult-to-ignite category B1 according to GOST 30244. This factor is their main advantage. Insulation PPZh contains inhibitors to increase corrosion resistance during contact with metal. Due to their optimal characteristics, they can be used for thermal insulation of reinforced concrete floors, as well as standard wall panels.
The compressive strength of the slabs during 10% deformation varies in the range of 0.1-0.8 MPa, the moisture absorption is 8.8% by weight and 2.7% by volume. The ultimate shear strength of the material is 0.01 MPa, the separation of layers is 0.042 MPa, the vapor permeability value is 0.049 Pa. Due to its convenient and stable shape and volume, the ППЖ 200 minelab is easy to cut and process. Plates are packed in 2-4 pieces with a protective shrink film, the volume of one pack is 0.08-0.12, taking into account the thickness.
Advantages and disadvantages
Insulation Rockwool PPZH 200 has its own advantages and disadvantages, which must be considered before purchasing. Of the advantages of mineral wool slabs of this type, they note:
- high level of mechanical tensile, compressive and tensile strength;
- increased heat resistance, melting of min-plates is possible only after 2 hours of exposure to a temperature of 1000 degrees;
- resistance to chemical components, damage from insects and rodents, mold formation;
- vapor permeability;
- durability, ability to maintain volume, shape, thickness and weight;
- no problems during installation and during processing, which allows you to cut slabs without much effort and use them for thermal insulation of complex structures.
Mineral slabs Rockwool, used for thermal insulation, have practically no drawbacks except for the high cost, as well as the specific smell of urea, which is added during the production process.
Areas of use
Minplate Rockwool PPZh 200 can be used for various construction needs. The brand's slabs are used to insulate load-bearing structures and floors, as well as roofs, wall panels, ceilings between floors and structures made of corrugated board or reinforced concrete. PPZh 200 are suitable for insulating plaster facades, but they need to be additionally reinforced with steel mesh. With their help, sound insulation is increased by laying mineral wool slabs under the cement screed in the floors.
Boards of this type are suitable for thermal insulation systems of industrial equipment, as well as for industrial premises. They have a wide range of applications, with sheets of PPZh 200 it is possible to insulate roofs of roofs and attic for the purpose of fire protection. Sheets help to further improve the fire resistance of materials and metal structures. In roof structures, slabs are responsible for the thermal insulation properties and strength of the entire roof as a whole. When used to insulate floors and floors, the sheets provide thermal and acoustic insulation.
Mineral wool board production process
Slabs ППЖ-200 from Rockwool are made from natural basalt raw materials, due to which mineral wool has good sound and thermal insulation properties. This effect is achieved by processing the raw materials using high temperatures. In the process, special fibers are formed inside the raw material, which are bonded to each other with the help of an adhesive and form individual plates. The resulting material fully retains its original qualities and has a long service life.
Minlabels belong to the category of environmentally friendly materials, since basalt rocks and gabbro are used for their manufacture without adding metallurgical waste. During production, the boards are melted to pull the fibers, a process similar to the formation of the material in natural conditions. PPZh-200 from Rockwool are created with the stacking of fibers in a chaotic manner, which favorably affects the technical characteristics of the material and reduces its weight.
The unique structure of the slabs allows them to maintain the required level of rigidity and not lose resistance to tearing. The material is impregnated with water-repellent oils to increase hydrophobicity, which allows the boards to be used even in high humidity conditions.
Rules for choosing insulation Rockwool PPZh 200
When buying PPZh-200 slabs, you need to take into account their technical features and characteristics, check them for compliance with the requirements. Rockwool materials from the manufacturer have a rectangular shape, the optimal level of density and rigidity. Small particles of fiber should not fall from them, high-quality slabs do not slip during installation and are able to maintain the initial volume. When choosing the plates, the dimensions of the insulation itself and the features of the installation object must be taken into account. Despite the incombustibility of PPZh-200, the plates should not be allowed to be located too close to the electrical wiring.
The combination of slabs with foil-clad mineral wool provides optimal thermal insulation. This mineral wool is a basalt insulation, pasted over with aluminum foil. Experts recommend paying attention to the density of products, the degree of resistance to loads and the ability of the plates to maintain their original shape even under strong compression depends on this indicator. For floors, ceilings and partitions, it is recommended to use heaters with a density of up to 50-100 kg / m3, for facades up to 100-125 kg / m3, for horizontal surfaces up to 35 kg / m3, under a screed up to 200 kg / m3.Materials with the correct density indicators provide maximum comfort and convenience at all stages of insulation operation.
The manufacturer recommends monitoring the storage conditions of the PPZh-299 plates, on which their quality largely depends. It is allowed to store the insulation on wooden pallets in durable polyethylene packaging, which must be undamaged. Also, the room needs to create optimal temperature conditions.
