Application area
Application area
It is used for dry finishing of premises.
Partitions C 111 are recommended for use as lightweight 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 built in any areas, including seismic ones.
An analogue of the C 111 partitions are the W 111 designs Knauf(Germany).
It is most appropriate to use in rooms with low 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 the plasterboard sheets is filled with insulating material made from mineral fibers.
The resulting surface of the partitions is suitable for applying various finishing coatings (paint, wallpaper, ceramic tile, structured plaster, etc.).
Installation process includes the following stages of work:
- Marking the design position of the partition along the floor, ceiling and base walls.
- Installation of the partition frame C 111.
- Installation of electrical wiring and embedded parts for fastening 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 posts insulating material, if provided for by the project.
- Installation and fastening of KNAUF plasterboard sheets (GKL) on the other side of the frame.
- Sealing seams between KNAUF plasterboard sheets (GKL) and priming the surface for decorative finishing.
- Decorative finishing of the partition after installing the finished floor.
Installation of partitions should be carried out during finishing works(V winter time with the heating connected), until the installation of clean floors, when all “wet” processes are completed and the wiring of electrical and plumbing systems has been completed, under dry and normal humidity conditions in accordance with SNiP 02/23/2003 “Thermal protection of buildings”. In this case, the room temperature should not be lower than 10°C.
In conditions high humidity(bathrooms, kitchens, bathrooms) it is recommended to use moisture-resistant KNAUF plasterboard sheets (GKLV), while it must be taken into account that in places where water directly hits the walls (bathrooms), the surface of the sheets should be covered with KNAUF-Flechendicht waterproofing.
Location electrical wiring in the space of the partition frame should exclude the possibility of damage to them by sharp edges of frame elements or screws during fastening of KNAUF plasterboard sheets (GKL).
The Knauf company is a leader in the production of plasterboard materials for dry construction. The advantages of the product include the ability to use it for various purposes: arranging walls and ceilings, protecting against fire or moisture, enhancing the heat and sound insulation qualities of the treated surface.
Kinds gypsum boards Knauf
Among the differences of the brand is the production of additional components - screws, profiles, and finishing materials– primers, putties, plaster mixtures and so on, which in combination with drywall form a reliable, durable and durable coating.
To avoid problems that arise when choosing and using these materials, the manufacturer Knauf provides special instructions for installing gypsum boards with a description of all the nuances of the work.
The Knauf company identifies several requirements that a frame for walls, partitions or a suspended ceiling must have before the cladding can begin. These include:
- To protect the material from the influence of dampness when the profile freezes, the cladding should be carried out with using Knauf GKVL;
- To prevent deformation of the structure under the weight of the drywall, long sections of profiles are installed staggered or in a checkerboard pattern with an overlap;
- As a connector of frame elements, a cutter (with a bend), an LN9 screw or a Knauf brand screw are used;
- To protect the material from deformation under the influence of vibrations created by the door and its weight, joining gypsum boards in the middle of the doorway is prohibited;
- After assembling the frame, it must be finished with thermal insulation tape.
Frame Knauf system collected from profiles of a certain format. Its choice depends on the type of work performed.
Types of Knauf profiles:
- UD – guide for ceilings;
- CD - ceiling carrier that forms the lathing;
- CW – bar for forming racks;
- UW – guide for installing partitions and walls.
List of Knauf profile markings Rules for installing gypsum boards on walls and partitions
The frame for a wall or partition made of gypsum plasterboard serves to provide additional heat and sound insulation, alignment, and masking of communications.
General points:
- Use Knauf K6/35 pin dowels as a fastening element for UW guides to the base of walls and ceilings, permissible distance between them – 1 m;
- As an element of fixing the CW profile to load-bearing wall use direct hangers, 1 pc. by 1.5 m of stand length;
- The CW profile pitch is 60 cm;
- Used for cladding walls and partitions plasterboard sheet format 2500x1200x12.5 cm;
- For decor under tiles or fake diamond two-layer cladding is used;
- Soundproofing tape is installed where the profile touches the walls and ceiling;
- The distance between the screws when covering is 25 cm;
- The gypsum plasterboard sheet is attached vertically to the wall frame and to the straight partition; for curly and radius structures - horizontally and by bending.

System suspended ceiling from profiles and plasterboard Knauf used to level, decorate, reduce the height of a room, and hide utility lines.
Key points:
- Install a sound insulator (Knauf self-adhesive tape) between the UD profile and the base of the ceilings;
- Use a pin dowel as a fastening element for the UD profile (1 piece for every 50 cm);
- Suspensions are installed at a distance of 90 cm along the line of fastening of the supporting profile;
- Step between load-bearing profiles– 40-50 cm, it is inserted with the base of the backrest to the side of the UD plank and fixed to the ceiling with a suspension;
- The distance between the screws for arranging the ceiling trim is 17 cm.
Installation of the gypsum board sheet to the ceiling starts from the corner of the room Working with GKLV:
- To cut niches, openings, holes for sockets, plasterboard/wood crowns and Knauf cutters are used for round holes or manually using a gravel;
- Before sheathing begins, the edge of the plasterboard sheet is chamfered: if Fkugenfüller putty is subsequently used, the chamfer angle is 45 degrees, if Uniflot is 22.5;
- To fix the casing to the metal frame, use fastening screws 25 mm long; the optimal deepening of the screw head will be ensured by the attachment to the screw for a Knauf NK 11 screwdriver;
- Begin to attach the gypsum board sheets to the frame with self-tapping screws from the center or corner, this will protect the material from deformation during the fixation process;
The sheets are installed closely together, the edge of the slab is located in the middle of the CW or CD profile.
Position of the gypsum board sheet relative to the profile Below you can see how the frame for partitions is installed and covered with Knauf materials.
Finishing work
At the end of the cladding, the manufacturer proposes to enhance the properties of gypsum fiber board additional processing surfaces with water-repellent compounds (Tiegenrgund primer) and Uniflot or Fugenfüller putty.
Sealing seams:
- Filling the seams with putty using a narrow spatula, removing residues and excess thickening of the mixture;
- Installation of seam tape;
- Cover the tape with a thin layer of putty, after 45 minutes remove any residue from its surface;
- Puttying screw heads;
- Secondary filling of the seam wide spatula, removal of residues;
- Manual grinding to eliminate unevenness;
- Installation in the area of the outer corners of the aluminum corner, PVC corner or aluminum tape, puttying;
- Installation of Knauf dividing tape between sheets of drywall and internal corner, puttying;
- After drying, the material is painted and plastered.
If all requirements and recommendations are met, the installation of partitions, walls or ceilings using Knauf materials will be successful and durable. But remember when doing this: the smoother you set the structure of the profiles, the smoother the surface will be in the end.
In contact with
Any master who has been engaged in repairs for more than one year or construction residential facilities, will confirm the manufacturability of the use of materials from the Knauf company. Practical developments German experts in the field plasterboard systems(read more) deservedly occupy leading positions in the design of walls and zoning elements of living space.
While a fair amount has already been written about walls, there is still an information vacuum about the method of proprietary organization of bulkheads. Therefore in this article Knauf partition system will be the focus of our attention.
Specification of Knauf enclosing structures
Use of "pie" in design GVL plasterboard significantly increases the fire safety of the premises. This development is especially in demand in boiler rooms, garages, and chimney areas. Such walls are able to localize the source of fire and prevent it from escaping.
This Knauf partition technology is based on the use of GVL slabs or its moisture-resistant analogue - GVLV. Both sides of the sheet are already treated at the factory with solutions of water repellents.
Total weight of 1 m² of structure including mineral wool slab 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
Here a double profile metal frame is used, which is sheathed on both sides Knauf GVL supersheets in two layers. Frame posts are separated sealing tape to improve sound insulation. This design has a number of benefits:
- light weight;
- effective fire safety;
- increase in labor productivity;
- suitable for any finish;
- improved sound and heat insulation properties.
Manufactured according to this system from Knauf company partitions used in buildings of any purpose, from residential to industrial. Experts recommend using this technology in rooms where the requirements for fire safety increased.
Where and for what is an acoustic partition from the Knauf company 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 a frame; the extra 10 mm will securely fix the cotton and prevent slipping. Due to the large number of voids between the fibers, soft insulation provides excellent sound absorption properties.
Experience in operating dividing walls with mineral wool proves them complete fire safety. Besides, acoustic baffle from Knauf is a heat insulator, which will save on heating costs. The presence of international certificates once again demonstrates the safety of the company’s products for the health of others.
conclusions
Zoning 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 technologies are within the capabilities of most private developers; all you need to do is acquire the right tool. Using moisture-resistant plasterboard, you can build a partition in a bathroom or toilet without much risk - it is only important not to deviate from the design principles.
The concept of “dry” construction implies the design and construction of lightweight frame-sheathing structures, the installation of which requires a minimum of money and physical effort. German KNAUF company produces high-quality materials necessary for such work and is a kind of legislator, defining standards for this type of activity. The KNAUF system for plasterboard partitions is known to any professional builder. Now it’s our turn to get to know these structures in more detail.
Series of partitions (according to KNAUF classification)
The company’s specialists classify all frame-sheathing partitions into several standard types:
| Horizontal sectional view | Construction type |
| C 111 – frame made of steel profile, covered with 1 layer of plasterboard sheets. | |
 |
C 112 - steel frame covered with gypsum plasterboard sheets in 2 layers. |
 |
C 113 - a “single” frame made of steel profile covered with a three-layer gypsum plasterboard covering. |
 |
C 115 – KNAUF partitions of this series have double metal carcass and 2 layers of sheathing made of gypsum plasterboard sheets. |
 |
C 116 – double steel frame with space for communications. The structure is covered with 2 layers of plasterboard on each side. |
 |
C 118 – “Intrusion protection”. The frame is made of steel profile and sheathed with gypsum board in 3 layers. Galvanized steel 0.5 mm thick is laid between the sheets. |
 |
C 121 - the frame of the partition made of wooden beams is sheathed with 1 layer of gypsum board. |
 |
C 122 – wooden frame with a two-layer gypsum plasterboard coating. |
For external coating of frame structures KNAUF company produces durable high-tech gypsum-based material that does not contain toxic substances, is absolutely non-flammable and has excellent operational properties. Drywall is produced in the form of KNAUF sheets (GKL) - rectangular elements consisting of a reinforced gypsum “core” covered with cardboard that has undergone special treatment.
Depending on the area of application, these sheets have different properties and are divided into types:
- GKL - used in rooms with normal humidity.
- GKLO – has increased fire resistance. The material is used for covering profile partitions installed in fire hazardous areas.
- GKLV is a moisture-resistant material. Its cardboard covering is impregnated with a special composition.
- GKLVO - combines the properties of moisture and fire resistance.
Except this KNAUF classifications The sheets differ in the type of side edge. All features of the material are indicated by markings that are applied to each sheet.
Features of the partition frame
Next constituent elements frame-sheathing structures KNAUF systems 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 weigh it down total weight. Let's consider what kind of profile is needed for a plasterboard partition, which will be made using the KNAUF system:
Tools and fasteners
The design features of KNAUF systems require strict compliance with all manufacturer’s recommendations regarding their installation. The company’s specialists pay great attention to the characteristics and quality of the fastening material used during assembly. frame partitions their drywall.
To connect the profiles to each other, it is recommended to use screws (self-tapping screws) for metal LN 9 and LB 9 (piercing and drilling). For Knauf fastenings sheets, self-tapping screws of type TN and TB with a length of 2.5–4 mm are used. The guide profile is attached to the ceilings with simple or anchor dowels measuring 4, 6, 8 or 12 mm.
1 - LN screw; 2 - LB screw; 3 - TN screw; 4 - TB screw
The design of a partition made of plasterboard from the KNAUF system is very simple, and for its installation all you need is simple tool, which is included in any “home” set:
- Tape measure, level, plumb line - for marking.
- Perforator - holes for dowels securing the guide profile.
- Screwdriver – installation of the frame and fastening of the casing.
- Metal scissors – cutting profiles to size.
- Construction knife - cutting drywall.
Installation stages
KNAUF specialists have developed step-by-step technology installation of plasterboard systems, implying a strict sequence of all work. So let's consider brief instructions for installation of plasterboard partitions:
- Marking. We mark a straight line on the floor with a dye cord, and then, using a plumb line or laser level, transfer this mark to adjacent walls and ceiling.
- Installation of a partition frame from a profile. We attach the PN profile to the floor and ceiling using dowels (every 80–100 cm). It must be secured to the ceilings by laying sealing material. We install and fasten in PN rack profile. The maximum distance between posts should not exceed 600 mm.
- Equipment installation. IN frame structure we install embedded elements (supports for cabinets, shelves, lamps, etc.). We install electrical wiring and all necessary communications.
- Frame cladding. We mount sheets on one side of the frame for the plasterboard partition, securing them with self-tapping screws every 250 mm.
- Laying sound insulation. We lay soundproofing material between the racks (as tightly as possible).
- Full lining. We attach the gypsum board to the remaining side of the frame. If the type of partition provides for multi-layer coating, each layer of sheets must be installed, shifting it by 600 mm from the previous one.
- Finishing. Having finished covering the frame, you need to putty the seams between the sheets and the heads of the fastening screws. Drywall must be primed for final decorative finishing.
This short review plasterboard systems developed by renowned 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 not an easy task like home renovation.

Drywall is widely used in apartment renovations. It is used to level walls and ceilings, construct niches and boxes, modernize doorways, and perform many decorative elements. There are certain rules for installing these structures that must be followed. Leading drywall manufacturers have developed entire kits for the convenience of consumers. Knauf technology has gained particular popularity in our country.
Benefits of using technology
Knauf produces a whole line of ready-made kits, varying depending on the type and size of the structure.
The main advantage of Knauf kits: they include everything necessary for installing a wall or partition, from drywall to fasteners. This gives the consumer several advantages, including:
- Use only guarantee quality materials. This is facilitated by a strict proprietary control system designed for minimum tolerances in the manufacture of gypsum boards and other elements.
- Ease of calculating the consumption of drywall and other parts of the structure. A simple online calculator, available on many websites, is sufficient. You need to enter the dimensions of your wall or partition into it, indicating the number of doors and windows, and it will display full list everyone necessary elements indicating their quantity.
- Each kit is supplied by the manufacturer detailed instructions assembly, thanks to which even an untrained person can carry it out.
- By purchasing materials separately, you may forget some details. Using the kit solves this problem.
Installation procedure for Knauf kits
Required preparatory work: alignment and marking. After this, a partition is placed:
- Guide profiles are attached to the dowels.
- Vertical posts are installed at selected optimal intervals. It is recommended to fix them using a cutter with a bend.
- Horizontal jumpers are installed.
- If necessary, communications are extended and insulation is installed.
- The gypsum board frame is sheathed with special branded screws.
- Conduct finishing corners and joints of sheets.
Installation features
The system for assembling walls and partitions using this technology has its own nuances that must be taken into account to achieve an optimal result:
- To ensure high strength, individual frame elements are reinforced by nesting one profile into another.
- The guides are attached to dowels at at least three points. The profile plane adjacent to the base is preliminarily covered with damper tape.
- Often it is necessary to join elements of metal structures that are not long enough. In this case, the connection points should be spaced, for example, placed in a checkerboard pattern. This will reduce the likelihood of vibrations or various deformations of the structure.
- The 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 using a cutter or branded self-tapping screws. Crab connectors are used at intersections.
- Sheathing elements made of gypsum plasterboard are attached end-to-end with the necessary gaps to compensate for the thermal expansion of the material. They will be filled in later special composition, produced by the same company "Knauf".
- When constructing gypsum plasterboard partitions that have window niches or doorways, it is prohibited to join the sheets above them. Otherwise, there is a risk of seams coming apart due to vibrations that occur when using windows and doors. The elements are joined 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 proprietary insulation based on mineral wool. The following kits are available:
- C 111 - with one layer of cladding. 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 beams for lathing.
- C 115 is a set with a double frame, lined with two layers of plasterboard. This allows, by increasing the thickness of the partition, to place a double layer of mineral wool in it. In terms of its characteristics, this design is close to an ordinary wall.
- C 116 - also performed on a double spaced frame. The internal cavities remaining inside it allow the production hidden installation communications. Two-layer cladding set away from the wall is implemented in kit C 626.
- C 113 or C 367 - sets with triple skin. Designed for cases where it is necessary to use drywall different types: Moisture resistant, fire resistant and regular in many combinations.
- C 118 – used for especially strong walls and partitions. In it, sheets of galvanized steel 0.5 mm thick are laid between layers of plasterboard.
- C 361, C 362, C 363 - sets on a single frame, sheathed in 1, 2 or 3 layers, respectively, with Knauf gypsum-fiber supersheets. From 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 you do not plan to hang anything heavy on the wall, and also if significant insulation or sound insulation is not required. But to attach it to the wall household appliances, which has considerable weight, you will have to make a double frame with reinforcement.
Features of the formation of corners from plasterboard
Important role in the device plasterboard construction angles 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.
Gypsum plasterboard structures can have both internal and external corners. To form each of them, their own techniques are used. First of all, the frame is assembled.
External corners are made as follows:
- Two vertical posts forming an edge are installed in the guides so as to form a single angle. It is unacceptable to install them offset: in this case, there will be a void under the joint of the drywall sheets.
- The racks are fixed in the guides with a pair of screws at each fastening point. Professionals prefer to use a cutter: such a connection does not contain any bulges that interfere with the tight fit of the plasterboard.
