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)- gypsum boards, 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; are used in rooms with dry, normal, damp 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 board 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 installing in places of overlap, a riveted connection is used, connection with LN9 screws or with a notch - 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:

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 moth nurseries) 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 pitch of the screws is about 20-25 cm. On the jumpers, it is advisable to turn 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.

Drywall is the most popular material for building partitions, decorative structures, niches in walls, openings, arches and much more. But all this requires a reliable support structure. They can be made from both wood and profile. Today, Knauf partitions are very popular. This is a drywall construction, the frame of which is made exclusively of a metal profile. At the same time, all sorts of nuances are observed that can harm the integrity and overall reliability.
What is Knauf technology?
The technology of Knauf plasterboard 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.
Knauf drywall installation technology involves 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 metal products 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 Knauf drywall installation instructions 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, using Knauf technology, partitions with channels for communications and ventilation are made. 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 are used to create a solid and reliable wall on which you can hang heavy furniture or some kind of household appliances.
The design of the Knauf partitions

Drywall is widely used in the renovation 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 Knauf kits: they include everything you need to mount a wall or partition, from drywall to fasteners. This provides the consumer with several benefits, including:
- Guaranteed to use only high 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 a complete list of all the necessary elements, indicating their number.
- The manufacturer provides each kit with detailed assembly instructions, so that 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
Mandatory 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.
- Carry out finishing processing of 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 preliminarily pasted over 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. In the future, they are filled with a special compound produced by the same Knauf company.
- 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 a full-fledged 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 battens.
- 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 allow for hidden installation of 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 use drywall of different types: moisture resistant, fireproof and ordinary 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 in order to attach household appliances that have a solid weight to the wall, you will have to make a double frame with reinforcement.
Features of the formation of corners from drywall
Corners play an important role in the installation of drywall construction. If they are assembled incorrectly, then after 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 external 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.
- Fragments of plasterboard sheathing are screwed end-to-end, so that the plane of one element overlaps the end of the other, and are reinforced with a special corner profile. You can fix it with putty or PVA glue.
Curvilinear ribs are reinforced with a flexible plastic corner.
Internal corners are formed a little differently:
- At the initial stage, an angle is made from the profile, twisting two racks so that the side back of one is attached to half of the back of the other. In this case, self-tapping screws LB19 mm or similar are used. Fastening is carried out every 25–30 cm.
- This design is inserted into the guides on the floor and ceiling and fixed with metal screws.
- Before installing drywall, chamfers are made with a slope of 45˚, they will facilitate the puttying of the corner.
- Internally, the rib is glued with a reinforcing mesh and puttied. After drying, it is treated with a primer for drywall.
