In repair and construction work applicable . This construction material has a flat surface, so you can easily create it, also with the help of partitions. Knauf partitions made of tongue-and-groove plasterboard have many advantages. The functionality of the partition is mainly aimed at dividing the room.
Knauf prefabricated plasterboard partition systems are used both in apartments and in public places. They differ in types and sizes. With their help, walls and partitions are created.
Assembling the Knauf partition frame The main advantage is the Knauf material. Tongue-and-groove gypsum slabs are created using lithium technology.
Required amount materials for installing partitions They do not burn and are . Composite boards do not contain toxic impurities harmful to humans and animals. Such slabs are easy to install and can be processed.
Knauf plasterboard partitions are fully equipped, which is important in the installation of the partition and its further use.
Types of partitions and installation features
The Knauf company produces partitions that are excellent in size and type. For convenience, they are divided into models.
Device diagram and design of the Knauf partition According to the design, Knauf partitions are divided into the number of layers of plasterboard (GLP):
- One layer of drywall.
- Two layers.
- Three layers of gypsum board.
- One layer on one frame.
- Combined drywall on one side and two-layer on the other side.
- Three-layer cladding of moisture-resistant plasterboard and metal sheets.
The design of the partitions has channels for communications, as well as dedicated spaces for ventilation. 
According to the Knauf frame, there are partitions: single-frame, designed for places where there is no need and there will not be a strong weighting of the structure. Two-frame structures are durable and can be used as a basis for creating furniture.
Partition C112
The Knauf S112 system is a composition of materials that create a partition with a two-layer cladding and one metal frame.
Partition features:
Considering everything Knauf features, we can say with confidence that its service life is long.
Names of Knauf partition elements Installation of partition C112
The partition installation technology is carried out in compliance with step by step instructions. Start off installation work should be carried out when all electrical work has been completed. After graduation repair work with flooring, as well as finishing water procedures in the required room.
Installation of the Knauf partition is carried out as follows:
- Using a laser and upholstery cord, markings are applied to the clean surface of the floor, walls and ceiling.
- The lines mark the location of the rack profiles, as well as the doorway.
- They are attached first. For profile cutting required length Scissors are used to cut metal.
- To improve sound insulation on the NP, it is necessary to glue a sealing tape according to the width of the profile.
- Using 35 mm dowels, the profile is attached to the floor. The fastening step is no more than 1 meter.
- Similarly, the NP is mounted on the ceiling.
- After this, you should measure the length of the rack profile from the ceiling to the floor.
Example of fastening rack profiles - The length should be 1 cm less than the height of the room.
- Sealing tape is glued to the rack profiles that are attached to the wall.
- If the wall is made of Knauf plasterboard, then profiles. If a brick or block is made of cellular concrete, then dowels 35 mm long are used. The spacing of fastening dowels or screws is no more than 1 meter.
Scheme for fastening Knauf plasterboard sheets - For doors weighing 35 kg, it is necessary to mount a double rack profile, by attaching one profile to another.
Diagram of a double rack profile device - Door racks are mounted in guide profiles and secured with self-tapping screws 9 mm long.
- A horizontal lintel for the door is cut from the guide profile. It is installed between the door post profiles, at the top of the door height and secured with 9 mm self-tapping screws.
- From the resulting door frame A cut-out rack profile in the amount of two pieces should be installed up to the ceiling. These racks are fastened using the perforation method with a bend.
Rack connection diagram 
- From floor to ceiling, rack profiles are installed every 60 cm, fixation is carried out using the cutting method.
Drawing with dimensions for mounting rack profiles - The backs of the profiles should be turned to one side, and the holes for the cables should be at the 1st level.
Plasterboard covering of partition C112
After the metal frame is mounted, it begins. The sheet should be fixed at a distance of 1 cm from the floor. If necessary, use construction knife. The cardboard is cut along the intended line and the plaster is broken.
On the other side, the cardboard should be cut along the resulting fold line. The cut part of the gypsum board is processed and a 22 degree chamfer is created. And also for cutting the sheet, cutters are used - small (the width of the cut sheet is 12 cm), a large cutter is 63 cm.
Installation of drywall is carried out using a special device. The sheets are pressed against the frame and... They should be at the same distance from each other - 7.5 cm, and also from the edge at a distance of no more than 15 cm. The head of the screw should be recessed into the gypsum board by 1 mm.
In the place where 2 sheets are connected vertically, a jumper from the profile should be installed. Adjacent horizontal joints are shifted by 40 cm.
After installing the plasterboard sheets, through the holes in metal racks Electrical wires and other cables should be installed.
Example of wiring under drywall The next step is installation insulating material Knauf insulation from the open side of the septum. And partition paneling plasterboard sheets. But, the drywall joints on one side should not coincide with the joints on the other side. In this way, the strength of the structure is created. 
After puttying, you should proceed to. In this case, the joints of the first layer of plasterboard should not coincide with the second level of plasterboard covering of the partition.
Using special equipment, it is necessary to cut holes at the designated points for electrical boxes for the switch and. 
Drilling holes for sockets The joints of the second layer of drywall must be sealed using Knauf reinforcing tape. After the putty has dried, the joints need to be grouted to remove excess pieces.
After grouting, the entire surface should be primed with Knauf Tiefengrund.
Detailed Process installing holes in drywall for sockets 
If the partition is to be painted, then before painting the entire surface should be puttied with Knauf Multi-Finish. When the surface is dry, it should be rubbed and coated with a primer.
Watch the video for the process of installing the Knauf partition.

Application area
Application area
Used as internal enclosing structures indoors various types, with dry and normal humidity conditions according to SNiP 02/23/2003, residential, civil and industrial buildings of all degrees of fire resistance and erected in any areas, including seismic ones.
It is used both in reconstruction and in new construction.
Most universal design, providing high performance, including special 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 surface is intended for subsequent final finishing, for example, wallpapering, painting, tiling, 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 partition frame C 112.
- Installation electrical wiring and embedded parts for fastening stationary equipment inside the frame.
- Installation and fastening of vertically oriented KNAUF plasterboard sheets (GKL) on one side of the frame.
- Installation and fastening of the second layer of vertically oriented KNAUF plasterboard sheets (GKL) to the frame.
- Sealing seams between KNAUF plasterboard sheets (GKL).
- Fixing insulating material in the space between the posts, if provided for by the design.
- Installation and fastening of KNAUF plasterboard sheets (GKL) on the other side of the frame.
- Sealing seams between KNAUF plasterboard sheets (GKL).
- Installation and fastening of the second layer 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 when the heating is connected), until the installation of clean floors, when all “wet” processes are completed and the wiring of electrical and plumbing systems has been completed, in dry and normal conditions humidity conditions according to SNiP 02/23/2003 “ Thermal protection 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.
The location of 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 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. The German company KNAUF produces quality materials necessary when performing such work and is a kind of legislator that determines the 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 – partition frame made of wooden beam covered with 1 layer of gypsum board. |
 |
C 122 – wooden frame with a two-layer gypsum plasterboard coating. |
For the external coating of frame structures, KNAUF produces a 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.
In addition to this classification, KNAUF sheets have differences 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. Much attention The company’s specialists pay 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 fastening Knauf 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 using simple or anchor dowels sizes 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. In the PN we install and fasten the 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.
