The gradual crowding out of the construction markettraditional materials with modern counterparts are not always conducive to meeting the needs of the consumer. By improving some, manufacturers sacrifice others. But there are many positive examples when, by all parameters, technologists achieve unsurpassed material properties. Confirmation of this are the Knauf tongue-and-groove slabs, which incorporate a complete list of the technical and physical qualities necessary to perform specific tasks.
Production technology and characteristics
The product is made of plaster materials andsolid plate shape. The finished construction product has a tongue-and-groove joint, due to which a bond with other fragments of the overall structure is provided.
The technological process of manufacturing platesincludes several stages, as a result of which a monolithic gypsum plate is formed. The solution, which is a mixture of water and plaster, 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 a semi-finished product. At the same time, the recipes of the initial mixture and other manufacturing parameters allow to produce Knauf tongue-and-groove gypsum boards in various modifications.
Technical and operational quality
Despite the differences within the gypsum familyKnauf brand, almost all variations of the product have similar operational properties. In constructional terms, 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 ductile raw material in mechanical processing - the structure of Knauf blocks is also easily corrected, allowing you to construct various structures without the need for special installation.
Also, gypsum slabs have a thickness of 8cm, which is a third less compared to peers. Knut groove plates and biological properties differ. In particular, they are free from damage by fungus, insects and mold. Under the influence of temperature and humidity changes, deformation processes and various forms of rotting are not observed.
The advantages of technological material for partitions include other qualities:
- Environmental cleanliness - usuallyinnovative building materials are losing traditional 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 - the plates 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.
- Low weight - elementary ease of transportation and installation is especially noticeable when compared with components for the construction of concrete walls.
Model line
The company "Knauf" offers gypsum in twobasic designs. The first variety is the standard, and the second is endowed with improved quality of protection against moisture. Conventional plates 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 hydrophobised additives, can be used even in the bathroom. Reliable protection against moisture penetration protects the material from deformation of the structure. Two types can be distinguished by special marking and shades: standard colors are gray, and modified plates are green.
Differences in gypsum plates also extend to the shape of the tongue-and-groove part. There is also a classification into two types: with a trapezoidal and rectangular cross-section.
Scope of application
Consideration of requirements for modern materials has expanded the field of construction, where Knauf tongue-and-groove slabs can be used. Technical specifications 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%.
- Heat conductivity - 0,29 W / m.
- Maximum compressive strength - 5 MPa.
- Bending strength - 2.5 MPa.
- Water absorption - maximum 5%.
Fire resistance, high noise insulation andThe environmental friendliness of the material also opens up opportunities for the widespread use of such structures in residential buildings. Already today, the demand for affordable funds for the reconstruction of real estate in the secondary market is increasing - gypsum panels are in the first positions as a basis for partitions.
Designers also appreciate Knauf tongue-and-groove tilesfor their decorative properties. One of the main tools of interior stylists is space zoning. The optimal solution is separation due to the externally pleasing and durable plaster material.
Mounting Features
The installation technique is simple and assumes a minimum"Dirty" operations. The main task of the master is to ensure reliable and accurate fixing of the blocks with glue. In choosing the latter one should be guided by a mixture of the same plaster base - such a combination will increase the adhesive effect. In the future, Knauf tongue-and-groove plates require only decorative finishing, and then in rare cases. The surface of the plates itself is aesthetically attractive, so it can be left in its original state. Maximum - for liner under the overall interior can be put 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 practices and reviews
In the eyes of the consumer, the described material demonstrates positive qualities from different sides. For example, Knauf tongue-and-groove plates, the price of which varies on average from 500 to 900 rubles / m2, effectively cope with the tasks of the device interroom partitions and masking surfaces.
The double slab is capable of providing noisetightness, and mechanically resistant construction, as evidenced by reviews of many supporters of the brand "Knauf". According to professional installers, gypsum plates are well thought out sizes. It is the strictness of the format that allows to embody constructional ideas in the form of multi-level partitions in which communication networks are laid with jewelry accuracy.
