The classification of this material is made according to purpose, technical characteristics, and area of use. According to the characteristics, there are such types of Knauf drywall: moisture-resistant, fire-resistant, perforated acoustic. Let's consider what are the differences between these coatings:
Considering that Knauf drywall can be installed on the floor, ceiling and walls, sheets are classified according to the same principle. The main difference between these types of material is the thickness of the sheets and their weight. For installation on walls and floors, sheets with a sufficiently large mass can be used, since they are mounted on a rigid frame. The ceiling cladding is made with thinner panels.

Installation technology
Installation instructions for Knauf drywall are not much different from the technologies for installing other materials of this type (Volma, Magma). Before starting the workflow, you need to prepare the wall. It is cleaned of old coatings, treated with primers and other protective compounds... In the presence of cracks and deep depressions, it is additionally plastered (you can not use putty).

Price overview by city
You can buy Knauf or Giprok drywall in almost any hardware store, the prices for the coating depend on the size of the sheet and its properties. Its sale is carried out in official dealerships or intermediary stores.
The concept of "dry" construction implies the design and construction of light frame-sheathing structures, the installation of which requires a minimum of funds and physical effort. The German company KNAUF produces quality materials necessary in the performance of such work and is a kind of legislator that defines the standards for this type of activity. The Knauf system for drywall partitions is known to any professional builder. Now it is our turn to get acquainted with these constructions in more detail.
Series of partitions (according to the Knauf classification)
The company's specialists classify all frame sheathing partitions into several standard types:
| Horizontal sectional view | Construction type |
| С 111 - a frame made of a steel profile, sheathed with 1 layer of drywall sheets. | |
 |
С 112 - the steel frame is sheathed with gypsum board sheets in 2 layers. |
 |
С 113 - "single" frame made of steel profile sheathed with a three-layer coating of gypsum plasterboard. |
 |
C 115 - KNAUF partitions of this series have a double metal frame and 2 layers of sheathing made of gypsum plasterboard sheets. |
 |
C 116 - double steel frame with space for communications. The structure is sheathed with 2 layers of plasterboard on each side. |
 |
С 118 - "Protection against penetration". The frame made of steel profiles is sheathed with gypsum board in 3 layers. Galvanized steel with a thickness of 0.5 mm is laid between the sheets. |
 |
С 121 - partition frame made of timber sheathed with 1 layer of plasterboard. |
 |
С 122 - wooden frame with two-layer plasterboard coating. |
For the outer coating of frame structures, the Knauf company produces a durable high-tech material based on gypsum, which does not contain toxic substances, is absolutely non-combustible and has excellent performance properties... Gypsum board is produced in the form of KNAUF sheets (GKL) - rectangular elements consisting of a reinforced gypsum "core" covered with specially treated cardboard.
Depending on the field of application, these sheets have various properties and are subdivided into types:
- GKL - used in rooms with normal humidity.
- GKLO - has increased fire resistance. The material is used for cladding partitions from a profile installed in fire-hazardous premises.
- GKLV - moisture resistant material... Its cardboard cover is impregnated with a special composition.
- GKLVO - combines the properties of moisture and fire resistance.
Besides this Knauf classification the sheets are distinguished by the appearance of the side edge. All material features are marked with markings that are applied to each sheet.
Partition frame features
The next constituent elements of the frame-sheathing structures of the Knauf system are metal profiles - strips of galvanized steel with a thickness of 0.5–0.8 mm. These products add strength to the frame, but do not make it heavier. total weight... Consider what kind of profile is needed for a plasterboard partition, which will be made according to the Knauf system:
Tools and fasteners
The design features of Knauf systems imply strict adherence to all manufacturer's recommendations regarding their installation. The company's specialists pay great attention to the characteristics and quality of the fastening material that is used during assembly frame partitions their drywall.
To connect the profile to each other, it is recommended to use screws (self-tapping screws) for metal LN 9 and LB 9 (piercing and drilling). For fastening Knauf sheets, self-tapping screws such as TN and TB are used with a length of 2.5–4 mm. The guide profile is fixed to the ceilings with simple or anchor dowels of 4, 6, 8 or 12 mm.
1 - LN screw; 2 - LB screw; 3 - TN screw; 4 - TB screw
The design of the KNAUF system plasterboard partition is very simple, and for its installation it is enough simple tool, which is in any "home" set:
- Roulette, level, plumb line - for marking.
- Perforator - holes for dowels, securing the guide profile.
- Screwdriver - installation of the frame and fastening the sheathing.
- Shears for metal - cutting a profile to size.
- Construction knife - cutting drywall.
Installation steps
Knauf specialists have developed phased technology installation of plasterboard systems, implying a strict sequence of all work. So let's consider short instruction for the installation of plasterboard partitions:
- Markup. We mark with a dyeing cord straight line on the floor and then using a plumb line or laser level, we transfer this mark to the adjacent walls and ceiling.
- Installation of the frame of the partition from the profile. To the floor and ceiling, with dowels (after 80–100 cm), we fasten the PN profile. It must be attached to the ceilings by laying a sealing material. In the PN we install and fix the rack-mount profile. The maximum distance between the uprights should not exceed 600 mm.
- Equipment installation. V frame structure we install embedded elements (supports for cabinets, shelves, lamps, etc.). We install electrical wiring and all the necessary communications.
- Frame cladding. On one side of the frame for a plasterboard partition, we mount sheets, fixing them with self-tapping screws every 250 mm.
- Installation of soundproofing. Between the racks (as tightly as possible) we lay soundproofing material.
- Full cladding. We fix the gypsum board on the remaining side of the frame. If the type of partition provides for a multilayer coating, each layer of sheets must be installed, shifting it 600 mm from the previous one.
- Finishing. After finishing the lining of the frame, you need to putty the seams between the sheets and the caps of the fastening screws. Plasterboard must be primed for the final decorative finish.
This short review gypsum plasterboard systems, developed by the well-known German company KNAUF, is a kind of instruction that must be followed when installing partitions. Additional questions that arise during your work will be carefully considered by our experienced specialists. Do not hesitate, we will give you an answer that will provide a "pleasant" result in such tricky business like home renovation.
Any master who has been repairing for more than one year or construction residential buildings, will confirm the manufacturability of the use of materials from the company Knauf. Practical developments of German specialists in the field of plasterboard systems (read more) deservedly occupy leading positions in the design of walls and zoning elements of living space.
While it has already been written decently about the walls, there is still an information vacuum about the methodology of corporate organization of bulkheads. Therefore, in this article Knauf partition system will be our focus.
Knauf Cladding Specification
The use of gypsum plasterboard GVL in the construction of the "pie" significantly increases the fire safety of the room. Such a development is especially in demand in boiler rooms, garages, chimney zones. Such walls are able to localize the source of fire and prevent it from breaking out.
This Knauf technology-partitions based on the use of plates GVL or its moisture-resistant analogue - GVLV. Both sides of the sheet are already treated at the factory with solutions of water repellents.
The total weight of 1 m² of the structure together with the mineral wool board and putty is about 18 kg. Allowed maximum height bulkheads up to 6.5 m.
Double metal frame and system from Knauf: C 365 partitions
A double profile metal frame is used here, which is sheathed on both sides superlists Knauf GVL in two layers... The uprights of the frame are separated by sealing tape to increase sound insulation. This design has a number of advantages:
- light weight;
- effective fire safety;
- increase in labor productivity;
- suitable for any finish;
- improved sound and heat insulation performance.
Manufactured according to this system from Knauf company partitions used in buildings for any purpose, from residential to industrial. Experts recommend using this technology in rooms where the requirements for fire safety increased.
Where and what is the Knauf acoustic partition used for?
Mineral wool materials Knauf insulation
available in the form of mats and slabs. Their width is 610 mm, which is very convenient for installation in the frame, the extra 10 mm will securely fix the cotton wool and prevent slipping. Thanks to a large number soft insulation provides excellent sound absorption properties.
The experience of operating dividing walls with mineral wool proves them complete fire safety... Besides, acoustic partition from Knauf is a heat insulator, which will save on heating. The presence of international certificates once again demonstrates the safety of the company's products for the health of others.
conclusions
The implementation of zoning of premises using Knauf products has a number of advantages:
- affordable price;
- lack of "wet" processes;
- the ability to control each stage;
- compliance with European standards;
- long service life.
Most of the technologies are quite within the power of most private developers, it is enough to acquire the right tool... Using the moisture-resistant gypsum board, you can build a partition in the bathroom or toilet without much risk - it is only important not to deviate from the design principles.
In the manufacture of a separate part of the interior or the implementation of the entire repair and construction project, you should adhere to the exact technology. Each manufacturer of the corresponding materials, mixtures and parts gives a number of recommendations for the use of their products, adhering to which you can achieve the expected effect during operation, and fit into the guaranteed period of use of the final product. Partitions of the Knauf system can be considered one of the most striking examples in the construction market, where the above axiom really works.
Why Knauf? This brand is known to many, but during repairs, not everyone decides to purchase materials of this brand, as they are afraid to go beyond the intended budget. Having considered the device of partitions from Knauf sheets, you will understand whether this method is yours, how it is remarkable, and how much the repairs on this system will cost.
To understand the essence and differences of these partition structures from other options, it is worth getting to know their types.
There are four types of such structures.:
- Partition model W111;
- Partition model W112;
- Partition W113 (fireproof);
- Security wall W118.
Each of these types has its own characteristics.
Arrangement of partitions according to the Knauf system - W 111
This structure consists of a frame, which is covered with plasterboard sheets on both sides. A layer of sound insulation must be placed inside the structure.
The guide profiles are fixed to the ceiling, walls and floor using dowels. After plating the gypsum board, the joints are sealed with a special "Uniflot" compound. The places where the walls are in contact with the ceilings are subjected to filling.
It happens that the structure reaches a length of 15 m, in this case it is necessary to make movable seams in it. Thanks to them, the partition will be able to linearly expand. To do this, two racks are placed in the place of the seam.
An insulating material is always placed between the profiles, and a metal profile with an elastic insert inside is placed between the drywall sheets.
You can also consider special cases of such partitions from the gypsum board:
- For example, the rack profile has a size of at least 75 mm, then the installation of a movable joint has such a feature - it is placed between two additional racks. They will be smaller in size than the main posts, the difference will be about 25 mm. Then the drywall sheets will have a thickness of 12.5 mm, this will compensate for the difference.
- If there is still a suspended ceiling in this room, then in order to soften the possibility of subsidence of the floor structure, the partition is fixed with a movable joint.
Partition W112
It also consists of a metal frame and drywall sheets, with which the frame is sheathed on both sides. There is a soundproofing layer between these sheets. The height can also be different, depending on the design objectives.
Installation techniques are similar to those above. The subtleties, in which the differences lie, are that the structure is sheathed on both sides with additional gypsum boards. This is done in order to improve the sound insulation properties and to increase the refractory properties of the device.
Partition W113
The partition includes all the same metal frame, which has a three-layer plasterboard cladding. There is a non-combustible soundproofing layer inside the device. It fits between sheets of drywall.
Since the design is distinguished by three-layer sheathing, the distance between the fixing of the guide profiles will be no more than 500 mm.
The surfaces of the air ducts pass through such partitions; they must have reliable fire protection. Often this is a casing with a fire resistance of over 0.5 hours.
Security wall W118
This type of device resembles the design features of the W113. But W118 differs in that a galvanized sheet with a thickness of half a millimeter is placed between the drywall sheets. The installation of this structure presupposes strict adherence to the requirements that are prescribed for fire walls.
This type of partitions has a reinforced frame, which is made of metal profile PS 100. The thickness of this profile is not less than 0.6 mm.
Factors influencing the choice of the type of complete partitions
The manufacturer of German construction products offers its customers big choice mounting kits plasterboard partitions... Today, there are more than twenty types of partitions. They are marked with the letter "C" with the prefix of the corresponding number (for example, C 111, C 115.2, etc.).
The specific type to be applied indoors will depend on several factors:
- total height of the room;
- permissible noise level;
- the supposed additional load on the wall;
- condition and type of material base surface fasteners;
- the need to bookmark / hide the communication systems in the box;
- the presence and type of door (pendulum, swing, sliding);
- the required height of the partition;
- humidity and temperature levels;
- type of premises and its functional purpose.
Dignity
On the territory of the post-Soviet countries, a couple of decades ago, the word "renovation" was firmly associated then with the exotic material "drywall". This and other related products of its production were first launched on the market of new generation building materials by the German Knauf firm... Along with this, the leading specialists of the enterprise have developed detailed instructions for the construction of suspended, frame and frameless structures lined with drywall sheets. High quality products in combination with a properly selected set of marketing techniques allowed the company to as soon as possible become a leader among competitors.
Today Knauf produces whole line sets for the manufacture of partitions, which, depending on the purpose, have a different configuration. Phased and detailed explanation the installation process allows you to install the partitions of the Knauf system with your own hands, without wasting time studying the building materials market and independently searching for the required structural components.
Also, the convenience of such kits lies in the simplicity of calculating the cost of one square meter finished product... In addition, determining the consumption of materials is also not difficult.
One of the important advantages of the set should be considered the exclusion of the factor of "forgetfulness". All necessary basic and additional details included in the kit.
The purchase of complete Knauf partitions will save you from various blunders and inconsistencies, which are very common when materials from various manufacturers are used for installation of a structure.
Component elements
Knauf has enough wide range of complete systems, each of which has a specific purpose and place of application.
Drywall Sheets
Depending on the conditions of use, as well as the properties of this cladding material, there are:
- ordinary sheets (GKL);
- refractory (GKLV);
- moisture resistant (GKLV);
- combined (GKLVO).
In addition, externally, the sheets differ from each other by the type of edge, depending onmethod of processing technological joints:
- PC - straight edge;
- ЗК - rounded edge;
- UK - edge, thinned from the front side;
- PLUK - an edge with a thinned and semicircular edge on the front side.
- PLC - round edge on the front side.
Depending on the field of application and the required dimensions of the final product, plasterboard of various dimensions is used for the installation of partitions:
- Length: 2000.0 mm to 4000.0 mm.
- Width: 600.0 mm and 1200 mm.
- Thickness: 6.5 mm to 24.0 mm.
Metal profiles
Represent hardware made of galvanized steel sheet. Used for the construction of a frame for plasterboard partitions. Standard length of these elements varies from 2750.0 mm to 4500.0 mm.
The parts have grooves on top, giving finished structure additional rigidity.
For mounting the base for drywall, two types of profile are used: guide (NP) and rack (SP). They must have comparable cross-sectional dimensions.
Feature of the guides Knauf profiles the presence of holes for fastening in them should be considered, which allows to reduce the coefficient of deformation of the part and, to a large extent, to reduce the time for installing the frame.
Data functional task metal elements is to hold the rack profiles in a given direction, as well as to stiffen the plasterboard partitions as a whole. In addition, it is used to make lintels inside a structure.
Rack profile
The section of the part has a C-shape. The joint venture is installed vertically.
It is fixed by means of the guide profile in one of three methods:
- end-to-end;
- by the nozzle method;
- by the "cut-off" method (used most often).
The side walls of the rack profile have holes for easy installation of electrical wires.
Wooden slats
Designed for manufacturing timber frame plasterboard partitions. These elements, as a rule, have a square cross section. Just like the metal frame, the wooden one has guides and rack parts. The vertical ones should be installed at the same distance from each other (as a rule, the spacing of the racks is 30.0 or 40.0 cm).
The moisture content of the material used for wooden base, should be in the range of 10-12%.
Additional components
In addition to the listed basic elements of the Knauf system partitions, various fasteners are also used, the type of which will depend on the difference general level the base plane, as well as the material from which the fastening surface is made and the degree of its wear.
To improve the soundproofing properties of the partitions, the voids of the frame must be filled with an appropriate material. The German manufacturer advises the use of mineral and fiberglass fillers that meet sanitary and epidemiological standards, with a high sound absorption index.
Installation technology
Installing this design is certainly similar to standard mounting... But nevertheless, the technology has its own characteristics, which I would like to focus on.
Features of the installation of partition structures according to the Knauf system:
- Knauf designers have developed some recommendations that must be adhered to at all stages of installation;
- Knauf partitions are equipped with guides (upper and lower), as well as racks, their width depends on the weight of the structure and on the height of the room;
- The guide profiles must be fixed to the overlap with dowels, the step will be equal to the step of the risers, you need to fix it in at least 3 places;
- Rack profiles will be fixed with a distance of 600 mm from each other, sometimes it can be less;
- The racks need to be fixed using the "punching with bend" method; Knauf self-tapping screws can also be used;
- If the structures are to be attached to false ceiling, the fire resistance class is always observed;
- As for sound insulation (and the partition should be like walls, soundproofed), mineral wool is most often used as an insulator layer;
- The peculiarity of installing sheets is that they must be installed without a gap, butt-to-end;
- The sheets should be laid in such a way that no cross-shaped seams are formed.
The installation of the frame also has its own characteristics - the joints of the GKL partition above the doorway should not be on the racks to which the box is attached. The seam should be placed on an intermediate rail that is installed above the horizontal beam. This, in turn, is the upper limit. These measures are necessary to ensure that the service life of the structure is long.
Obviously, without using plaster and other "wet" elements of repair, the cost construction works decreases. Therefore, the difference between these materials, and materials of the lower price segment, is compensated by savings on the same plaster.
Partition walls are plasterboard devices that change the look of a room. These walls, built on their own, allow you to zone an apartment, divide rooms into functional parts, and at the same time be separate decorative element... Knauf experts are constantly looking for new technologies and studying the market for demand for construction products. Through the use modern methods production and the desire to expand the sales market, complete partitions of the Knauf system for many years have remained the leader in their field, annually offering consumers more advanced new products.
Prefabricated KNAUF plasterboard partition systems (video)
The Knauf company is a family-owned German company, which, having begun its history in 1933 with the production of gypsum building mixtures and having passed almost a century of development, today it represents not only materials, but also technologies. "Knauf", releasing drywall, gives recommendations on how to build walls and partitions according to the original technology that guarantees quality.
Plasterboard can serve not only for finishing a room, such as walls or ceilings, but also as a separate building material for creating partitions.
Drywall is widely used today, it is inexpensive and practical material... It is difficult to imagine how much he made life easier for modern builders. It is difficult to overestimate the benefits of its use in interior and finishing works... Indeed, in addition to leveling the walls and creating curly ceilings, in addition to building various niches, arches and others architectural forms, GKL ( gypsum plasterboard) can also serve as an independent building material used for the construction of walls and partitions indoors.
And in this regard, "Knauf" offers its own technology for mounting drywall, offering to build on, first of all, what result needs to be obtained.
Basic types of structures
The technology of installation of GKL "Knauf" is slightly different depending on the type of partition used. O characteristic features, if there are any, let's talk separately, for each specific structure. Distinguish the following basic systems GKL "Knauf".
111
This is the most simple construction representing supporting frame made of a steel profile, sheathed on both sides with plasterboard sheets, filled with insulating material. The thickness of such a plasterboard partition is minimal and is equal to the sum of the width of the bearing profile and the thickness of the sheets of material. Such a design is rather decorative in nature, since it is not able to withstand heavy loads and can easily be destroyed by physical contact. Partitions made of gypsum plasterboard according to the "Knauf" s111 system are used in those places where there is no need for a high level of heat and noise insulation and the structure itself is needed, rather, for visual separation of the space.
112
Partitions made of gypsum plasterboard according to the Knauf s112 system are made in a similar way, their main difference is that drywall is sewn in two layers on each side. This increases the strength of the finished structure, improving it performance characteristics... More durable to mechanical stress, they, however, cannot replace full-fledged walls.
113
This variety differs from the first two in that it is sheathed with three sheets of drywall on each side. This approach is usually used where it is necessary to combine different types of GCR.
Types of GKL Knauf:
- normal;
- moisture resistant (wall color green);
- fire-resistant (wall color red);
- combined GKLVO.
Depending on the area of application, they can be used in various combinations... For example, the walls of corridors intended for evacuation in case of fire are sheathed with fire-resistant sheets.
115
Plasterboard partitions "Knauf", made according to this system, are a double metal frame, sheathed with a double layer of drywall sheets. This approach allows to increase the thickness of the final wall, as well as to increase its insulating characteristics by using a double layer of insulation inside. The double metal frame, in turn, makes such a wall strong enough. The Knauf ceilings made according to this technology can already be considered a full-fledged wall.
When using this technology, it is necessary to lay an insulating tape between the joints metal frames.
An important point is the laying of a heat-insulating tape at the junction of two metal frames, this is necessary so that the wall does not freeze through, condensation does not form in it and it retains high operational properties.
116
In contrast to system 115, transverse spacers made of gypsum plasterboard are used here, designed to increase the thickness of the wall and leave space inside for wiring all the necessary pipes and communications. Essentially, inside the walls, an artificial cavity is formed for technical use.
118
This type of partitions is made using technology 113 with the only difference that between the layers of drywall, the wall is sheathed with galvanized steel half a millimeter thick. Such a structure is designed to maintain its consumer properties even if an attempt is made to break it. Of course, such a wall will not withstand a grinder, but it will take time to demolish it, so the use of structure 118 in order to protect against penetration is fully justified.
121 and 122
The GKL Knauf partitions made using this technology are practically the same as the 111 and 112 systems, with the only difference that the frame here is made of wood.
General rules
Important to remember. Separately, it is worth talking about the installation of all the specified gypsum board partitions using the "Tigi Knauf" technology, this method involves the arrangement of sheets of different layers overlapping each other. Or in a runaway, as they say. That is, the joints of the sheets at different levels should not intersect. Instructions for the construction of partitions using this technology indicate that the joints of the slabs different levels must be at least half a meter apart. This applies to both vertical and horizontal joints. Observing this rule, you will greatly increase the strength of the finished structure.
Choosing knauf systems you get no individual elements, and ready-made engineering systems.
The use of Knauf gypsum plasterboard systems implies the work of a complete closed cycle, in which all materials and components are used only by this manufacturer. This approach is useful in many ways. The fact is that Knauf does not just produce various elements, this company supplies ready-made engineering systems in which everything is thought out.
Each small part individually, in its place, forms an overall monolithic result. Here's what you need to work with this technology:
- Profiles. At "Knauf" bearing and guide profiles are made in such a way that when mounting one to the other, distortions, distortions and other anomalies do not occur. The finished frame, built from the specified material, is always even, strong and reliable.
- Filler, or insulator. It is recommended to use only mineral wool from the specified manufacturer. It does not spread combustion, does not rot, does not support organic life forms, which means that mice in such walls will not start. In addition, such wool is made for the width of the inter-wall space and does not require additional processing.
- The plasterboard of this manufacturer itself, which meets all European quality standards, in combination with the rest of the elements of this designer, is able to carry many years of good-quality service.
- Rough and finishing compositions for grouting and sealing, created taking into account the composition of cardboard and gypsum filler of this particular brand, successfully complement the drywall from this manufacturer, showing excellent adhesion properties to its surface. Thus, the finished wall with a rough finish already looks complete.
- An insulating tape of the required width for a specific profile, as well as all hardware for work, should also be chosen from the products of the specified brand. After all, the quality of these elements has been tested and certified, as well as tested over many years of use. Don't question the quality finished wall saving on fasteners. After all, it is on it that all these components are held.
Conclusion
As you can see from the above, Knauf technology for walls and partitions made of plasterboard is a reliable and calculated engineering system, which is purchased in parts, but, being assembled on site, represents a direct integration of German quality into the Russian interior.
