Knauf slabs: reviews and technical data

Gradual displacement in the construction markettraditional materials with modern analogs does not always help meet the needs of the consumer. Improving some qualities, producers sacrifice 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 inform 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.

Technological process of manufacturing platesincludes several stages, as a result of which a monolithic gypsum plaster 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 family of gypsum platesbrand Knauf, almost all product variations have similar performance properties. In the structural aspect, an almost ideal 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 the construction of various structures without the need for special installation.

Also, gypsum plaster partitions have a thickness of 8cm, which is a third less compared to 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 there are no processes of deformation and different forms of rot.

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

Ecological cleanliness - as a rule,innovative building materials are losing 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

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

Differences in gypsum plates also extend to the form of the pile-and-groove part. Here, too, there is a classification into two types: with a trapezoidal and rectangular section.

Scope of application

Accounting for the requirements for modern materials has expanded the area of construction, where the Knauf canopies can be used. The 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 andecological compatibility of the material also opens the possibility for wide use of such structures in residential buildings. Already today there is a growing demand for affordable means for real estate reconstruction in the secondary market - gipsplits occupy the first positions as a basis for partitions.

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

Mounting Features

The installation technique is simple and involves a minimum"Dirty" operations. The main task of the master is to ensure reliable and accurate fixation of blocks with glue. In choosing the latter, it is worthwhile to rely on mixtures of 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 shows positive qualities from different sides. For example, the Knauf pile-and-groove plates, the price of which varies on average from 500 to 900 rubles per m², effectively cope with the tasks of the device inter-apartment partitions and masking surfaces.

A double plate is capable of providing both noisetightness, and mechanically stable construction, as evidenced by the reviews of many adherents of the brand "Knauf." In the opinion of 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 the design ideas in the form of multi-level partitions, in which communication networks are laid.
