The gradual displacement of traditional materials on the construction market by modern analogues does not always contribute to satisfying consumer needs. Improving some qualities, manufacturers sacrifice others. But there are many positive examples when, in all respects, technologists achieve unsurpassed material properties. Confirmation of this is the Knauf tongue-and-groove plates, which incorporate a complete list of technical and physical qualities necessary to perform specific tasks.
Production Technology and Characteristics
The product is made of gypsum materials and in the form of a solid plate. The finished construction product has a tongue-and-groove joint, which ensures bonding with other fragments of the general structure.
The technological process for the manufacture of plates includes several stages, as a result of which a monolithic gypsum plate is formed. The solution, which is a mixture of water and gypsum, is poured into a special form. Then the liquid evaporates, and the resulting mass passes the final drying procedure. Thus, a full-fledged building material is created from the semi-finished product. At the same time, the initial mixture formulations and other manufacturing parameters make it possible to produce Knauf tongue-and-groove gypsum boards in various modifications.
Technical and operational qualities
Despite the differences within the Knauf family of gypsum plates, almost all product variations have similar performance properties. In a structural respect, an almost perfect surface and strictly calculated tongue-and-groove elements are noted. There remains the opportunity to refine the material. As you know, gypsum is a malleable raw material in machining - the structure of Knauf blocks is also easily adjusted, allowing you to build various structures without the need for special installation.
Also, partitions made of gypsum plates have a thickness of 8 cm, which is a third less than analogues. Knauf tongue-and-groove plates differ in biological properties. In particular, they are free from damage by fungus, insects and mold. Under the influence of temperature and humidity differences, processes of deformation and various forms of decay are not observed.
The advantages of technological material for partitions include other qualities:
- Environmental cleanliness - as a rule, innovative building materials lose to the traditional ones precisely because of their synthetic origin. But in this case, the gypsum base makes the product completely safe due to the absence of toxicity.
- Fire resistance - stoves do not support the combustion process, which affects the fire safety of the room.
- Noise isolation - sound absorption of a double design reaches 48 dB.
- Light weight - the basic convenience in transportation and installation is especially noticeable when compared with components for the construction of concrete walls.
Model line
The Knauf company offers gypsum boards in two main executions. The first variety is the standard, and the second is endowed with improved quality of protection against moisture. Conventional stoves are designed for installation in rooms with average humidity indicators. In turn, Knauf tongue-and-groove plates , the moisture - resistant properties of which are due to hydrophobized additives, can be used even in the bathroom. Reliable protection against moisture penetration protects the material from deformation of the structure. Two varieties can be distinguished by special marking and shades: standard ones are gray, and modified plates are green.
Differences in gypsum plates extend to the shape of the tongue-and-groove part. There is also a classification into two types: with a section of a trapezoidal and rectangular shape.
Scope of application
Taking into account the requirements for modern materials has expanded the field of construction, where Knauf tongue-and-groove plates can be used. Technical characteristics of the structures are as follows:
- Density - not less than 1,250 kg / m3.
- Gypsum mass is 22 kg.
- Humidity - does not exceed 12%.
- Thermal conductivity - 0.29 W / m.
- The maximum compressive strength is 5 MPa.
- Bending strength - 2.5 MPa.
- Water absorption - maximum 5%.
Fire resistance, high noise insulation and environmental friendliness of the material also open up opportunities for widespread use of such structures in residential buildings. Already today the demand for affordable means for reconstruction of real estate in the secondary market is growing - gypsum boards occupy the first positions as the basis for partitions.
Designers also appreciate the Knauf tongue-and-groove slabs for their decorative properties. One of the main tools of interior stylists is the zoning of space. The optimal solution is the separation due to the externally pleasant 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 fixation of blocks with glue. In choosing the latter, it is worth focusing on mixtures from the same gypsum base - this combination will increase the adhesive effect. In the future, Knauf tongue-and-groove plates require only decorative finishes, and even then in rare cases. The surface of the plates itself is attractive aesthetically, so it can be left in pristine condition. Maximum - for eyeliner under the general interior, you can apply a layer of putty or other topcoat. The use of plaster is unnecessary, since all the protective qualities and a smooth surface already characterize the finished partition.
Use practice and reviews
In the eyes of the consumer, the described material demonstrates positive qualities from different angles. So, for example, Knauf tongue-and-groove slabs, the average price of which varies from 500 to 900 rubles / m 2 , effectively cope with the tasks of arranging interroom partitions and masking surfaces.
The double plate is able to provide both noise tightness and a mechanically stable design, as evidenced by the reviews of many adherents of the Knauf brand. According to professional installers, gypsum boards are well thought out sizes. It is the strictness of the format that allows jewelry designers to accurately embody structural ideas in the form of multi-level partitions in which communication networks are laid.
