In repair and construction work applicable. This building material has a flat surface, so you can easily create it, as well as using partitions. Knauf partitions made of tongue-and-groove drywall 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.
Assembly of the Knauf partition frame The main advantage is the Knauf material. The tongue-and-groove gypsum boards are created using lithium technology.
The required amount of materials for the installation of the partition They do not burn and are. Composite plates do not contain toxic impurities harmful to humans and animals. These boards are easy to install and process.
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 their sizes and types. For convenience, they are divided into models.
Scheme of the device and the design of the Knauf partition By design, Knauf partitions are divided into the number of layers of drywall (GWP):
- One layer of drywall.
- Two layers.
- Three layers of plasterboard.
- One layer on one frame.
- Combined drywall on one side and two-layer - the second side.
- Three-layer sheathing of moisture-resistant GKL and metal sheets.
The design of the partitions has channels for communications, as well as dedicated places for ventilation. 
According to the Knauf frame, there are partitions: single-frame, designed for places where there is no need and there will be no heavy weighting of the structure. Two-frame structures are durable, which can either be used as a basis for creating furniture.
Partition C112
The Knauf C112 system is a composition of materials that create a partition with a two-layer sheathing and one metal frame.
Partition features:
Given all the features of Knauf, it is safe to say that its service life is long.
The names of the elements of the Knauf partition Installation of partition C112
The installation technology of the partition is carried out in compliance with the step-by-step instructions. Installation work should begin when all work with electricity and is completed. After the completion of repair work with flooring, as well as the end of water procedures in the required room.
Installation of the Knauf partition is carried out as follows:
- With the help of a laser and an upholstery cord, markings are applied to a clean surface of the floor, walls and ceiling.
- The lines mark the location of the rack profiles, as well as the doorway.
- Attached first. Metal shears are used to cut the profile to the required length.
- To improve sound insulation on the NP, it is required 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 not more than 1 meter.
- Similarly, the NP is mounted on the ceiling.
- After that, you should measure the length of the rack profile from the ceiling to the floor.
An example of fastening rack profiles - The length should be 1 cm less than the height of the room.
- A sealing tape is glued to the rack profiles that are attached to the wall.
- If the wall is Knauf drywall, then profiles. If the brick or block is made of cellular concrete, then dowels 35 mm long are used. The step of fastening dowels or self-tapping screws is not more than 1 meter.
The scheme of fastening sheets of drywall Knauf - For doors weighing 35 kg, it is required to mount a double rack profile, by fitting one profile onto another.
Scheme device double rack profile - Racks for doors are mounted in guide profiles and fastened with self-tapping screws 9 mm long.
- A horizontal lintel for the door is cut out of the guide profile. It is installed between the rack profiles of the door, at the top of the door height and fastened with 9 mm self-tapping screws.
- From the resulting door frame to the ceiling, you should install a cut-out rack profile in the amount of two pieces. These racks are fastened with a notch with a bend.
Rack connection diagram 
- Rack profiles are installed from floor to ceiling every 60 cm, fixing is carried out by cutting.
Dimensional drawing for mounting rack profiles - The backs of the profiles must be turned to one side, and the cable openings must be at level 1.
Plasterboard sheathing of partition C112
After the mounted metal frame begins. The sheet must be fixed at a distance of 1 cm from the floor. If necessary, use a construction knife. The cardboard is cut along the intended line and the gypsum is cracked.
On the other hand, the cardboard should be cut along the resulting fold line. The trimmed part of the GKL is processed and a chamfer of 22 degrees is created. And also cutters are used to cut the sheet - 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 screw head should be 1 mm recessed into the plasterboard.
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 drywall sheets, electricity wires and other cables should be pulled through the holes in the metal racks.
Example of wiring under drywall The next step is to lay the Knauf insulation on the open side of the partition wall. And sheathing partitions with plasterboard sheets. But, drywall joints on one side should not coincide with 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 drywall should not coincide with the second level of the drywall coating of the partition.
Using special equipment at the marked points, it is required to cut holes for the electrical boxes for the switch and. 
Drilling holes for sockets The joints of the second layer of drywall must be sealed with Knauf reinforcing tape. After the putty dries at the joints, it is required to make a grout from excess pieces.
After grouting, the entire surface should be primed with Knauf Tiefengrund.
Detailed process of mounting holes in drywall for sockets 
If the partition is painted, then before painting the entire surface should be puttied with Knauf Multi-Finish. When the surface dries, it should be rubbed and covered with a primer.
See in the video the installation process of the Knauf partition.
Complete system KNAUF for the dry method of finishing the premises includes:
- basic materials: plasterboard sheets, metal profiles;
- Additional materials- putty mixtures, reinforcing tapes, primers, screws, etc., as well as
- tool and technical information about designs and methods of production.
This series contains instructions on the selection of the type and design of frame and frameless wall cladding made of plasterboard sheets, as well as working drawings of wall cladding units.
Types of system linings KNAUF
Note: the mass of one square. meter cladding is calculated for the case of using plasterboard sheets with a thickness of 12.5 mm.
Depending on the properties and scope of the sheets are divided into the following types:
- Plasterboard sheets (gypsum plasterboard)- plasterboard sheets, used mainly for interior decoration of buildings and premises with dry and normal humidity conditions.
- Moisture resistant plasterboard sheets (GKLV)- plasterboard sheets with reduced water absorption (less than 10%) and increased resistance to moisture penetration; used in rooms with dry, normal, humid and wet humidity conditions in accordance with the current standards for building heat engineering.
- Plasterboard sheets with increased resistance to open flame (GKLO)- gypsum plasterboards, which have greater resistance to fire than ordinary ones; used in areas with high fire hazard.
- Moisture resistant plasterboard sheets with increased resistance to open flame (GKLVO)- plasterboard sheets that simultaneously have the properties of GKLV and GKLO sheets.
When using GKLV and GKLVO sheets in rooms with humid and wet conditions, exhaust ventilation should be provided to ensure normal air exchange in accordance with the current building codes for heating, ventilation and air conditioning (See KNAUF AutoCAD Nodes below).
The humidity regime of the premises of buildings and structures in winter, depending on the relative humidity and temperature of the indoor air, should be established according to Table 1 of SNiP II-3-79 * "Construction Heat Engineering"
Gypsum boards are available with various types of longitudinal edges
The sealing of the joints of the GKL with the edges of the UK and PLUK types is carried out using a reinforcing tape.
The PLUK edge, in addition, allows the sealing of gypsum plasterboard joints without reinforcing tape, which reduces the number of operations, consumption and range of materials.
The PC edge serves mainly to form the second skin layer in the C626 cladding.
End edges are rectangular.
Metal frame made of galvanized metal profiles according to TU 1111-004-04001508-95
metal profiles KNAUF are manufactured in accordance with TU 1111-004-04001508-95 and are long elements made by cold rolling a thin steel strip 0.55-0.8 mm thick using modern equipment.
Standard profile length KNAUF is 2750, 3000, 4000, 4500 mm.
The maximum profile length is 9000 mm.
Rack profiles (PS) have a C-shape and serve as vertical racks of frames designed for plasterboard linings. A rack profile is mounted in a pair with a guide profile of the appropriate size.
PS profiles KNAUF are produced with the following cross-sectional dimensions:
It is allowed to connect rack profiles along the length (1.073.9–2.00.1–9). When mounting in places of overlap, a riveted connection, connection with LN9 type screws or with a notch is used - using the “notch with a bend” method.
Guide profiles (PN) have a U-shape and serve as guides for rack profiles, as well as for the installation of jumpers between them in the cladding frames. Mounted in tandem with a corresponding size PS-profile.
PN profiles KNAUF are produced with the following section sizes:
(PNP 28×27) has a U-shape and serves as a guide for the ceiling profile, as well as for the installation of jumpers between them in the frames of the C623 cladding. Mounted in tandem with an appropriately sized ceiling profile (PP 60×27).
Ceiling guide profile (PNP 28×27) is produced with pre-drilled holes F 8 mm in the profile wall with a step of about 250 mm. for fastening it to the supporting base.
Ceiling profile (PP 60×27) has a C-shape and serves as vertical racks of frames intended for cladding with plasterboard sheets. Mounted in tandem with an appropriately sized ceiling guide profile (PNP 28×27).
Soundproof and heat-insulating materials
As a soundproofing and heat-insulating layer in plasterboard linings of the system KNAUF it is necessary to use products made of mineral and fiberglass on a synthetic binder and other materials included in the "List of polymeric materials and structures approved for use in construction by the Ministry of Health of the USSR" - M.1985 and having a fire safety certificate and a hygiene certificate for use in premises for the corresponding purpose .
Fasteners
The following types of fasteners are used for fastening the gypsum plasterboard to the cladding frame and fastening the elements of the cladding frame to each other:
a) for attaching the GKL to the frame:

The concept of "dry" construction implies the design and construction of lightweight frame-sheathing structures, the installation of which requires a minimum of funds and physical effort. The German company KNAUF produces high-quality materials necessary for the performance of such work and is a kind of legislator that sets the standards for this type of activity. The Knauf system for plasterboard partitions is known to any professional builder. Now it is our turn to get acquainted with these structures in more detail.
Series of partitions (according to Knauf classification)
The company's specialists classify all frame-sheathed partitions into several standard types:
| Horizontal Sectional View | Construction type |
| C 111 - frame made of steel profile, sheathed with 1 layer of drywall sheets. | |
 |
C 112 - the steel frame is sheathed with GKL sheets in 2 layers. |
 |
C 113 - a "single" frame made of steel profile is sheathed with a three-layer coating of GKL. |
 |
C 115 - Knauf partitions of this series have a double metal frame and 2 layers of cladding made of plasterboard sheets. |
 |
C 116 - double steel frame with space for communications. The structure is sheathed with 2 layers of drywall on each side. |
 |
C 118 - "Protection against penetration." The framework from a steel profile is sheathed by GKL 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 plasterboard. |
 |
C 122 - a wooden frame with a two-layer coating of GKL. |
For the outer 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 performance properties. Gypsum board is produced in the form of KNAUF-sheets (GKL) - rectangular elements consisting of a reinforced gypsum "core" covered with cardboard that has undergone special processing.
Depending on the 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 sheathing profile partitions installed in fire hazardous rooms.
- GKLV - moisture resistant material. Its cardboard coating 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 marked with a marking that is applied to each sheet.
Partition frame features
The next constituent elements of 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 give strength to the frame, but do not weigh down its overall weight. Consider which profile is needed for a plasterboard partition, which will be made according to the KNAUF system:
Tool and fasteners
The design features of Knauf systems require strict adherence to all manufacturer's recommendations regarding their installation. Specialists of the company pay great attention to the characteristics and quality of the fastening material, which is used in the assembly of frame partitions of 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 fixing Knauf sheets, self-tapping screws of the TN and TB type, 2.5–4 mm long, are used. The guide profile is attached to the ceilings with simple or anchor dowels of 4, 6, 8 or 12 mm in size.
1 - LN screw; 2 - LB screw; 3 - TN screw; 4 - TB screw
The design of the Knauf drywall partition is very simple, and for its installation, the simplest tool that is in any "home" set is enough:
- Roulette, level, plumb - for marking.
- Perforator - holes for dowels that secure the guide profile.
- Screwdriver - installation of the frame and fastening of the skin.
- Scissors for metal - cutting the profile to size.
- Construction knife - cutting drywall.
Installation steps
Knauf specialists have developed a step-by-step technology for installing drywall systems, which implies a strict sequence of all work. So, consider a brief instruction for installing a plasterboard partition:
- Markup. We mark a straight line on the floor with a coloring cord, and then, using a plumb line or a laser level, we transfer this mark to adjacent walls and ceiling.
- Installation of the partition frame from the profile. To the floor and ceiling, with dowels (after 80–100 cm), we fasten the PN profile. It must be fixed to the ceilings by laying sealing material. In PN we install and fasten the rack profile. The maximum distance between posts should not exceed 600 mm.
- Equipment installation. We install embedded elements in the frame structure (supports for cabinets, shelves, lamps, etc.). We install electrical wiring and all 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.
- Soundproofing installation. Between the racks (as tightly as possible) we lay soundproofing material.
- Full upholstery. We fix the GKL on the remaining side of the frame. If the type of partition provides for a multi-layer coating, each layer of sheets must be installed, shifting it by 600 mm from the previous one.
- Finishing. Having finished facing the frame, you need to putty the seams between the sheets and the caps of the fixing screws. Drywall must be primed for the final decorative finish.
This brief overview of drywall systems, developed by the famous German company Knauf, is a kind of instruction that must be followed when installing partitions. Additional questions that arise in the course of work will be carefully considered by our experienced specialists. Rest assured, we will give you the answer that will provide a "pleasant" result in such a difficult task as home renovation.
Hello, hello, our brave plasterboarders. Today you will find a cool tutorial on the topic of drywall partitions. Speaking specifically, we will disassemble a single-layer partition on a single frame - C 111 according to the Knauf classification, because. such partitions are most widespread. We will deal with the general principles of their installation, how to form a doorway, an external corner and pairing several partitions with each other. As an example, we will take a corner partition with a doorway, such as pantries and dressing rooms (essentially nurseries for moths) are usually enclosed to store pickles / jams and all sorts of junk that is long overdue to be disposed of.
Please note that work with drywall can only be carried out after the plaster and screed in the apartment have completely dried.
To begin with, let's get acquainted with the special profiles that serve to form the frame of the partitions. These profiles are called rack-mount. To be more precise, there are exactly rack-mounted PSs (CW), and there are also special wide guides PN (UW) for them. Dimensions of guide profiles: 40×50, 75, 100 mm. In our example, profiles with a width of 100 mm will be used. The letters C and U in their bourgeois name indicate the shape of their section. As you can see in the picture, the guide shelves are straight, like the horns of the letter U, and the rack - with roundings, like the C. By the way, the shelves are called the side edges of the profiles, and the walls are the back. The second letter of the overseas name means that the profiles are rack-mounted, i.e. wall from the German "Wand".
Rack and guide profiles Knauf
They are in paired version.
Once again, we repeat that you can only use a profile with a metal thickness of 0.55-0.6 mm, for example, Knauf. They are good not only because of the rigidity, but also because their design allows you to insert them into each other, thereby achieving their elongation and reinforcement on the sides of the doorway. Profiles from other manufacturers may not be able to do this. In the walls of the PN there are already ready-made holes with a diameter of 8 mm for dowels.
Dimensions of rack profiles: 50×50, 75, 100 mm. For single-layer partitions, the 50th posts are rather weak, so we advise you all to take the 75th or 100th. In the walls of the Knauf rack profiles there are 3 pairs of closely spaced holes with a diameter of 33 mm for laying wires.

On the next slide on the left - a self-tapping screw with a press washer, it serves to fasten the profiles together. There is an option with a drill and without. They are designated, respectively, LB and LN. On the slide - option LN. In our case, they are needed only if there is no cutter. On the right is a drywall screw. More precisely, it is all the same for metal, but it already serves to fasten sheets of the Civil Code to the profiles. Therefore, most often it is called that - a drywall screw. Has a secret, so-called. carob, head. Designated - TN. There is also a TB, with a drill at the end, but you can do without it, 0.6 mm steel TNs will easily be taken.
Self-tapping screws for mounting structures made of plasterboard
Do-it-yourself instructions for installing a plasterboard partition.
Step 1. Markup
For example, let our partition be a continuation of an existing wall. It is highly desirable to pre-align the beacons. We draw a line-the continuation of the wall on the ceiling, we make a right angle with a simple square. This line is the inner border of our future partition, taking into account its final dimensions. But we first need to mount the frame, and for it the dimensions are different. It is not necessary to draw your own lines for the frame, you can make everything easier. How? Find out very soon...
Marking lines on the ceiling
For now, we transfer the lines from the ceiling to the floor using a plumb line and a cord breaker, or a laser level.
Transfer markings to the floor
And now in front of you is the very simplified way of marking the PN.
Mark holes for fasteners
The bottom line is that pieces of drywall are sewn onto the guide profiles cut to size, which are already set along the lines. With this approach, the risk of error will be minimal. We mean that later, when the Civil Code sheets are sewn on, the rule will not “jump” at the wall/partition boundary. Pieces of GKL should be sewn flush with the walls of the PN. We expose the profile with these pieces along the line and put marks with a pencil or marker where we will have holes for attaching the PN to the base.
From a different angle
Step 2. Fixing the PN
Then, according to our marks, holes are drilled in the base, and a sealing tape is necessarily glued to the profiles. Its absence is capable of completely ruining the entire soundproofing of the future partition. With it, the adjunction to the base will be very tight, which also affects the crack resistance of the structure. The fastening itself is carried out with dowel-nails using an ordinary hammer. Fast and strong.
Attaching the profile to the dowel-nails
Guides on the floor
Near the opening
On the ceiling
We do not unscrew the pieces of GKL from the profiles until we fix the PN at all the necessary points. Often there are situations when the holes available in the PN are not enough. In these cases, they should be drilled independently, and you can do it in one go - through the profile to the base. The main thing is to carefully monitor that the boundaries of the GKL pieces clearly coincide with the marking lines. After fixing the guides on the sides of the doorway, I advise you to check them with the rule and make sure that they lie exactly on the same line.
You need to make at least three attachment points per profile. Even if it is 30 cm long. Usually, the fastening pitch is made in the region of 50 cm. If the floor is uneven, the pitch is reduced. Sometimes you even have to divide the PN into several segments. We do the same on the ceiling. Then we unscrew the pieces of GKL, but do not throw them away, they will still be useful to us ...
Step 3. Mounting wall substations
Fastening racks to walls
We cut the rack profiles in height, insert them into the guides close to the walls and drill holes in the walls right through them. Try to maintain a step of about 50 cm, no more. We hammer the dowel-nails into these holes again. Do not forget to glue the walls of the profiles with sealing tape! And control them by the rule, they should not be bent. By the way, the height of the substation must be less than the height of the ceilings in the room, at least 1 centimeter. They should not support the ceiling.
The length of the racks is 1 cm less than the height of the ceiling
As you can see, there is some distance between the rack profile and the floor.
Step 4 Installing the frame posts
The rack profiles of the frame are installed in increments of 60 cm. If tiles are laid on the partition, then in increments of 40 cm. The profiles of the doorway are extraordinary, and they do not affect the pitch of the remaining substations. The slide shows the profiles set at 60 and 80 cm from the wall. Near PS just forms a doorway.
Partition frame posts
To reliably form an opening, the side PSs are made double, that is, one PS is inserted into the other. Of course, this is done in such a way that the holes in the walls of these profiles coincide in height. Inserting the PS into each other is not an easy task, sometimes you have to walk on them with your feet so that they snap into place along the entire length. It turns out that on the slide you see 3 profiles, but in fact there are 4 of them.
PS are set in one direction - with the wall to the corner from which the plasterboard sheathing will begin. The maximum weight of the door leaf that a pair of PS-100 can withstand is 40 kg. Rack profiles are installed strictly vertically. Their length should be 1 cm less than the height of the ceilings. And the holes in all profiles must be at the same height. Profiles can be fixed to the rails using a cutter or self-tapping screws with a press washer (temporarily). Before patching the GKL, all self-tapping screws must be unscrewed.
Racks in place
Yes, PS are installed in one direction, because the fastening of sheets should begin from that part of the profile shelf, which is closer to its wall. If you do the opposite, the screws will jam the profile shelf, and it may bend. On the slide you see an almost finished partition frame. Let's take a look at how the outside corner is formed correctly...
Forming the outer corner
Frame from another angle
One of the rack profiles is turned with the wall outward, and the second one stands with a shelf towards us. A distance equal to the thickness of the GKL was left between them, we laid it at the stage of fixing the PN. Thus, the GK sheet on the inside of the partition will wind up, as it were, into its depths. At the end of the article, the outer corner of the fully finished partition will be shown in section.
Step 5 Jumper
Jumper from PN
It remains for us to make a jumper for the doorway. It is made from a guide profile by making an oblique incision of its shelves and bending a part of its length by 5-7 cm. The slide clearly shows how it will look. That is, you will need to cut a piece of PN 10-14 cm longer than the width of the opening. Cut and fold it symmetrically. On each side, the jumper is attached to the side posts with 2-3 LN screws.
Installing a jumper in the frame
Now our frame is completely finished. It is possible to pass electric cables through the frame. But you should not bring them inside the profiles, as they can be pierced with TN screws when sheathing the GKL.
Step 6. GKL sheathing
Sheathing the frame with drywall
BEFORE jumpers
There are several rules here.
- We have already mentioned the first one - you cannot join sheets on the side profiles of the opening.
- Secondly, cruciform joints of the “+” type are unacceptable, only of the “t” type.
- Thirdly, the joints of the sheets on the inside and outside should be horizontally shifted by a profile step, and vertically by at least 40 cm. On the slide, you can see the very pieces of drywall that we used for marking. Now they serve us as props. After all, the sheets of the Civil Code cannot be placed directly on the floor, they must be raised above it by about 1 cm.
- And they should not reach the ceiling either, about half a centimeter. This is the fourth rule.
To fix the drywall to the double posts of the opening, you can use small metal drills. Otherwise, very often self-tapping screws simply jam the inside of the profile. First, drill holes through the gypsum board, then screw the screws into them. Of course, sheets can only be joined horizontally on profiles, which means that we must make jumpers from PS at the joints. See how they look on the next slide.
PS jumpers
These are segments of conventional rack profiles. To fix them, again, you need to start from the side of the shelf, which is closer to the wall. In the matter of mounting the jumpers, it is desirable to have an assistant who will hold the sections of the profiles while you turn the screws in them. As soon as all the jumpers are placed, it is possible to lay soundproofing plates (mineral wool) between the profiles. We like ISOVER the most. When laying, we try not to leave unfilled areas. It should be cut off with a margin of about 5 cm so that it abuts against the profiles and thus keeps in the frame. When working with mineral wool, be sure to use goggles, a respirator and gloves!
Sheathing process
Sheathing process 2
Finished skin
The step of the screws is about 20-25 cm. On the jumpers, it is advisable to twist them more often, after 10-15 cm. Make sure that the heads of the screws are deepened into the sheet, but do not pierce the cardboard. If the cardboard is pierced, the screw should be twisted. More importantly, the screws must enter strictly at right angles. They must be at least 15 mm from the edge of the end edge of the sheet and at least 10 mm from the longitudinal edge. By the way, GKL can only be mounted in a vertical position! If a stretch ceiling is planned in the room, it is advisable to mount PS mortgages under it in the partition, into which we recommend additionally inserting a beam of the appropriate size.
I also recommend screwing self-tapping screws into the jumpers on both sides of the partition, and not just from the side of the joint. It is advisable to adjust the location of the sheets on the outer corner so that they lie on it with the factory edge. Then, when we install a protective corner on it, it will deepen and the plane will not deteriorate. Of course, all progressive mankind has long been using a special corner-proof paper tape, Sheetrock, for example. But we know that it’s hard to find one in our country, so our Stone Age has dragged on, and we still use outdated metal corners. So, the partition is assembled.
