Occupation pm 05 components of the Knauf system. Partitions standards according to the unified Knauf classification. How much does cladding cost
Any master who has been repairing or construction residential facilities, will confirm the manufacturability of the use of materials from Knauf. Practical developments German specialists in the field drywall systems(read more) deservedly occupy a leading position in the design of walls and zoning elements of living space.
If decently has already been written about the walls, then there is still an information vacuum about the method of corporate organization of bulkheads. Therefore, in this article Knauf partition system will be our focus.
Specification of enclosing structures Knauf
Use in "pie" construction drywall GVL 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 partition technology based on the use of GVL boards or its moisture-resistant counterpart - GVLV. Both sides of the sheet are already treated with water repellent solutions at the factory.
The total weight of 1 m² of construction, together with mineral wool board and putty is about 18 kg. A maximum bulkhead height of up to 6.5 m is allowed.
Double metal frame and system from Knauf: partitions C 365
It uses a double profile metal frame, which is sheathed on both sides Knauf GVL supersheets in two layers. Frame racks are separated sealing tape to improve sound insulation. Such a design has a benefits:
- light weight;
- effective fire safety;
- increase in labor productivity;
- suitable for any finish;
- improved sound and heat insulation performance.
Made according to this system from Knauf partitions are used in buildings of any purpose, from residential to industrial. Experts recommend using this technology in rooms where the requirements for fire safety raised.
Where and why is an acoustic partition from Knauf used?
Mineral wool materials Knauf Insulation Available in both mat and slab form. 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. Due to the large number of voids between the fibers, the soft insulation provides excellent sound-absorbing properties.
The operating experience of separating walls with mineral wool proves them complete fire safety. Besides, acoustic partition from Knauf is a thermal 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 benefits:
- affordable price;
- absence 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 moisture-resistant GKL, you can build a partition in the bathroom or bathroom without much risk - it is only important not to deviate from the design principles.

Drywall is widely used in the repair of apartments. With its help, walls and ceilings are leveled, niches and boxes are constructed, doorways are modernized, and many decor elements are performed. There are certain rules for the installation of these structures that must be observed. Leading drywall manufacturers have developed entire kits for the convenience of consumers. The Knauf technology has gained particular popularity in our country.
Benefits of Using Technology
Knauf produces a whole line of ready-made kits that differ depending on the type and size of the structure.
The main advantage of the kits Knauf: they include everything you need to mount a wall or partition, from drywall to fasteners. This provides the consumer with several benefits, including:
- Guaranteed use only quality materials. This is facilitated by a strict system of company control, designed for minimum tolerances in the manufacture of plasterboards and other elements.
- Ease of calculating the consumption of drywall and other parts of the structure. A simple online calculator available on many sites is enough. You need to enter the dimensions of your wall or partition into it, indicating the number of doors and windows, and it will give full list all necessary elements indicating their number.
- Each set is supplied by the manufacturer detailed instruction for assembly, thanks to which even an unprepared person can carry it out.
- Buying materials separately, you can forget some details. Using the kit solves this problem.
The procedure for installing Knauf kits
Required preparatory work: alignment and marking. After that, a partition is placed:
- Guide profiles are attached to the dowels.
- Vertical racks are installed at selected optimal intervals. Their fixation is recommended to be done using a cutter with a bend.
- Horizontal jumpers are mounted.
- If necessary, communications are stretched, insulation is laid.
- GKL frame is sheathed with special proprietary self-tapping screws.
- Spend finishing corners and joints of sheets.
Mounting Features
The system for assembling walls and partitions using this technology has its own nuances that must be taken into account in order to achieve the optimal result:
- To ensure high strength, individual frame elements are reinforced by nesting one profile into another.
- The guides are attached to the dowels at least three points. The plane of the profile adjacent to the base is pre-pasted with a damper tape.
- Often it is necessary to join insufficiently long elements of a metal structure. In this case, you should space out the junctions, for example, place them in a checkerboard pattern. This will reduce the likelihood of vibrations or various deformations of the structure.
- Racks are placed at a distance of 600 mm from each other. Thus, each sheet will be fixed on three profiles. If necessary, the step between the racks can be reduced.
- The profiles are fastened together with a cutter or branded self-tapping screws. Crab connectors are used at intersections.
- GKL sheathing elements are fastened end-to-end with the necessary gaps to compensate for the thermal expansion of the material. Later they are filled special composition, produced by the same company "Knauf".
- When building partitions from gypsum boards with window niches or doorways, it is forbidden to join sheets above them. Otherwise, there is a risk of seams coming apart due to vibrations that occur when using windows and doors. Docking of elements is carried out closer to the corners of the room.
Types of structures provided by Knauf
The sets differ from each other in the number of skins, thickness and frame design. All partitions use branded insulation based on mineral wool. There are the following kits:
- C 111 - with one layer of sheathing. The minimum thickness and instability to loads do not allow such a design to replace full wall, its function is decorative and zoning.
- C 112 - sheathing in two layers on each side on a single frame.
- Sets C 121 and C 122 are similar to the two described above. The difference is that instead of profiles, they use wooden bars for the crate.
- C 115 - a set with a double frame, lined with two layers of drywall. This allows, by increasing the thickness of the partition, to place a double layer of mineral wool in it. According to its characteristics, this design is close to a conventional wall.
- C 116 - also performed on a double spaced frame. The internal cavities remaining inside it make it possible to produce concealed installation communications. The two-layer sheathing removed from the wall is implemented in the C 626 kit.
- C 113 or C 367 - sets with triple skin. Designed for those cases when it is necessary to apply drywall different types: moisture resistant, fireproof and common in many combinations.
- C 118 - used for extra-strong walls and partitions. In it, sheets of galvanized steel 0.5 mm thick are laid between the layers of drywall.
- C 361, C 362, C 363 - sets on a single frame, sheathed, respectively, in 1, 2 or 3 layers with Knauf gypsum fiber supersheets. C 365–369 - modifications of partitions with gypsum fiber on different frames.
- C 386.1 and C386.2 - kits that provide for the laying of ventilation or other communication channels.
Various combinations of frames and skins are possible. All of them are presented in the Knauf product line.
A single frame is used when it is not planned to hang anything heavy on the wall, and also if significant insulation or soundproofing is not required. But to attach to the wall household appliances, which has a solid weight, you will have to make a double frame with reinforcement.
Features of the formation of corners from drywall
important role in the device drywall construction corners play. If they are assembled incorrectly, then through a short time cracks will appear in these places, and the fastening of the sheets will be unreliable.
GKL structures can have both internal and outside corners. For the formation of each of them, their own methods are used. First of all, the frame is assembled.
External corners are made as follows:
- Two vertical posts forming a rib are installed in the rails so as to form a single angle. It is unacceptable to mount them with an offset: in this case, there will be a void under the junction of the drywall sheets.
- The racks are fixed in the guides with a pair of self-tapping screws at each attachment point. Professionals prefer to use a cutter: such a connection does not contain bulges that interfere with the tight fit of the GKL.
HELPFUL INFORMATION: Is it possible to paint drywall without prior putty?
Drywall is the most popular material for building partitions, decorative designs, niches in the walls, openings, arches and much more. But all this requires reliable support structure. They can be made from both wood and profile. Very popular today Knauf partitions. This is a drywall construction, the frame of which is made exclusively of metal profile. At the same time, all sorts of nuances are observed that can harm the integrity and overall reliability.
What is Knauf technology?
Technology Knauf drywall walls lies primarily in the use of high-quality and reliable materials:
- screws;
- putty, mesh and more.
The advantages of the Knauf profile include the fact that when docking a rack-mount with a guide, no bumps and protrusions form on the wall surface. And this is a definite plus, because it allows you to save money on finishing mixtures.
Mounting technology drywall Knauf provides for the use of branded moisture-resistant sheets. Materials from this manufacturer also have increased resistance to both mechanical factors and moisture. The range of this type of product includes sheets of 5 standard sizes, which greatly speeds up the installation process. And as a heater and sound insulator it is used exclusively.
Heat and sound insulation Knauf Knauf fasteners and hardware are made of durable types of plastics, and hardware undergo anti-corrosion treatment.
The company is engaged in the production of a huge number of product names, so almost everything should be used from this brand.
What are the benefits of Knauf technology?
The main difference between Knauf products is high durability and excellent quality. Therefore, Knauf drywall installation technology must be performed at the appropriate level. Technology does not allow careless attitude and poor quality work. When starting to build partitions using this technology, you should adhere to all its principles:
If the installation instructions for Knauf drywall are fully observed, then the partition will turn out to be reliable and durable.
Types of partitions Knauf
According to the structural structure of Knauf, partitions can be of several types, depending on the number of skins:
- with a single layer;
- with double skin;
- with three-layer sheathing;
- with a single-layer sheathing of Knauf-supersheets of moisture-resistant sheets on a single frame;
- with combined, on the one hand, and two-layer, on the other;
- with a three-layer sheathing of moisture-resistant sheets and intermediate steel sheets.
Also on Knauf technologies partitions are made with channels for communications and ventilation. These include designs of grades C 386.1 and C 386.2.
The type of partition to be installed depends on the purpose of the room and the degree of its sound insulation.
Knauf partitions are also divided according to the type of frame:
- double;
- single.
Single structures are used in places where thorough sound insulation is not required, and no additional load will be applied to the walls. Double applied to create a strong and secure wall, on which it will be possible to hang heavy furniture or some household appliances.

Partitions lined with sheet materials Knauf are designed for installation in residential, public and industrial buildings.
The use of partitions according to Knauf technology in most cases turns out to be more profitable in comparison with known structures made of piece materials (brick, blocks, etc.), since the installation speed of Knauf partitions is higher, the weight is less, and wet processes excluded from work.
An additional advantage of dry construction systems is the ability to quickly dismantle.
Knauf has developed a range of specialized partitions to meet increased requirements in the field of fire safety, sound insulation, shock resistance and even X-ray protection.
The use of special systems and well-chosen types of Knauf sheets makes it possible to achieve high values of fire resistance and the level of airborne sound insulation for various rooms.

Application area
Application area
It is applied at finishing of rooms in the dry way.
Partitions C 111 are recommended for use as light internal enclosing structures in rooms with dry and normal humidity conditions according to SNiP 23-02-2003, residential, civil and industrial buildings of all degrees of fire resistance and erected in any areas, including seismic ones.
An analogue of the C 111 partitions are the W 111 structures of the Knauf company (Germany).
It is most expedient to use in rooms with a small height in the absence of high requirements for fire resistance and sound insulation.
If there are requirements for thermal, sound and fireproof insulation, the cavity of the partition between drywall sheets filled with insulating material made of mineral fibers.
The resulting surface of the partitions is suitable for applying various finishing coatings (paint, wallpaper, ceramic tile, structured plaster, etc.).
Mounting process includes the following stages of work:
- Marking the design position of the partition on the floor, ceiling and base walls.
- Installation of partition frame C 111.
- Installation of electrical wiring and embedded parts for fixing stationary equipment inside the frame.
- Installation and fastening on one of the sides of the frame vertically oriented plasterboard Knauf sheets(GKL).
- Fastening in the space between the racks insulating material if provided by the project.
- Installation and fixing of KNAUF plasterboard sheets (GKL) on the other side of the frame.
- Sealing joints between KNAUF plasterboard sheets (GKL) and priming the surface for decorative finishing.
- Decorative finishing of the partition after the device of the finishing floor.
Partition walls should be installed within finishing works(V winter time with connected heating), before the installation of clean floors, when all the "wet" processes are completed and wiring of electrical and plumbing systems is completed, in dry and normal humidity conditions in accordance with SNiP 23-02-2003 "Thermal protection of buildings". In this case, the temperature in the room should not be lower than 10°C.
In conditions high humidity(bathrooms, kitchens, bathrooms) it is recommended to use moisture-resistant KNAUF gypsum plasterboard sheets (GKLV), while it must be borne in mind that in places where water directly hits the walls (bathrooms), the surface of the sheets should be covered with KNAUF-Flachendicht waterproofing.
Location electrical wiring in the frame space of the partition should exclude the possibility of damage to them by the sharp edges of the frame elements or screws during the fastening of Knauf plasterboard sheets (GKL).
