Knauf slabs: reviews and technical data

Gradual replacement in the construction market of traditional materials by modern analogues does not always help to satisfy consumer demands. Improving some qualities, the producers donate to others. But there are also many positive examples, when technologists achieve the unsurpassed properties of the material by all parameters. This is confirmed by the Knauf pile-and-groove plates, which include a complete list of technical and physical qualities necessary for performing specific tasks.

Production technology and characteristics

The product is produced from plaster materials and in the form of a solid plate. The finished building product has a punctiform block, due to which the fastening with other fragments of the general construction is ensured.

The technological process of manufacturing plates includes several stages, as a result of which a monolithic gypsum plate is formed. A solution is poured into the special form, which is a mixture of water and gypsum. Next, the liquid evaporates, and the resulting mass passes the final drying procedure. Thus, a complete building material is created from the semi-finished product. In this case, the formulas of the initial mixture and other manufacturing parameters allow the production of Knauf gypsum plasterboards in different modifications.

Technical and operational qualities

Despite the differences within the Knauf family of gypsum plasters, almost all variations of the product have similar performance properties. In the structural aspect, an almost perfect surface and strictly calculated pile-and-groove elements are noted. Remains and the opportunity to refine the material. As is known, gypsum is a compliant raw material in machining - the structure of Knauf blocks is also easily adjusted, allowing construction of various structures without the need for special installation.

Also, the partitions made of gypsum plates have a thickness of 8 cm, which is one third less than in analogues. The Knauf pazogrebnev plates differ in their biological properties. In particular, they are spared from fungus, insects and mold. Under the influence of temperature and humidity fluctuations, deformation processes and various forms of rotting are not observed.

To the merits of technological material for partitions are other qualities:

  • Ecological cleanliness - as a rule, innovative building materials lose traditional because of the synthetic origin. But in this case the gypsum base makes the product completely safe in the absence of toxicity.
  • Refractoriness - the plates do not support the combustion process, which affects the fire safety of the room.
  • Sound insulation - sound absorption of a double design reaches 48 dB.
  • A small mass - an elementary convenience in transportation and installation is especially noticeable when compared with the components for the erection of concrete walls.

Model ruler

The firm "Knauf" offers gypsum plates in two basic versions. The first variety is the standard, and the second is endowed with an improved quality of protection against moisture. Conventional slabs are designed for installation in rooms with medium humidity parameters. In turn, the Knauf pile-groove plates, whose moisture-proof properties are due to hydrophobic additives, can be used even in the bathroom. Reliable protection against moisture penetration protects the material from deformation of the structure. The two varieties can be distinguished by special markings and shades: the standard ones have a gray color, and the modified plates are green.

Differences in gypsum plates extend to the shape of the parison. There is also a classification into two types: with a trapezoidal and rectangular section.

Scope of application

Accounting for the requirements for modern materials has expanded the areas of construction where Knauf canopies can be used. Technical characteristics of the structures are as follows:

  • Density - not less than 1 250 kg / m3.
  • The weight of the gypsum plate is 22 kg.
  • Humidity - does not exceed 12%.
  • The thermal conductivity is 0.29 W / m.
  • The maximum compressive strength is 5 MPa.
  • The flexural strength is 2.5 MPa.
  • Water absorption - maximum 5%.

Fire resistance, high noise insulation and environmental friendliness of the material also provide opportunities for the widespread use of such structures in residential buildings. Already today, there is a growing demand for affordable funds for real estate reconstruction in the secondary market - gypsum plates occupy the first positions as a basis for partitions.

Designers also appreciate the Knauf slabs for their decorative properties. One of the main tools of interior stylists is space zoning. The optimal solution is separation due to a pleasant externally and durable gypsum material.

Mounting Features

The installation technique is simple and involves a minimum of "dirty" operations. The main task of the master is to ensure reliable and accurate fixing of blocks with the help of glue. In choosing the latter, it is worthwhile to rely on mixtures from the same gypsum base - this combination will increase the adhesive effect. Subsequently, the Knauf slabs require only decorative finishing, and then in rare cases. The surface of the plates itself is attractive aesthetically, so it can be left in its original state. Maximum - for padding under the general interior it is possible to put a layer of putty or other finishing coating. The use of plaster is unnecessary, since all the protective qualities and smooth surface already characterize the finished partition.

Practice of use and feedback

In the eyes of the consumer, the material described demonstrates positive qualities from different sides. For example, Knauf pile-and-gouge plates, whose price varies on average from 500 to 900 rubles per square meter, effectively cope with the tasks of the device of inter-apartment partitions and masking surfaces.

The double plate is capable of providing both noise tightness and a mechanically stable structure, as evidenced by the reviews of many adherents of the Knauf brand. According to professional installers, gypsum plates are well thought out in standard sizes. It is the severity of the format that allows the jeweler to accurately embody constructive ideas in the form of multi-level partitions, in which communication networks are laid.
