Complete system KNAUF for the dry method of finishing 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 production methods.
This series contains instructions for selecting the type and design of framed and frameless wall cladding from plasterboard sheets, as well as working drawings of wall cladding units.
Types of system cladding KNAUF
Note: weight of one sq. meter of cladding is calculated for the case of using plasterboard sheets with a thickness of 12.5 mm.
Depending on the properties and scope of application, sheets are divided into the following types:
- Regular plasterboard sheets (GKL)– plasterboard sheets, used primarily for interior decoration 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 current standards for building heating engineering.
- Plasterboard sheets with increased resistance to open flame (GKLO)- plasterboard sheets that have greater fire resistance than ordinary ones; used in areas with increased fire hazard.
- Moisture-resistant plasterboard sheets with increased resistance to open flame (GKLVO)— plasterboard sheets that simultaneously have the properties of gypsum board and gypsum board sheets.
When using GKLV and GKLVO sheets in rooms with humidity and wet conditions, it is necessary to provide exhaust ventilation, ensuring normal air exchange in accordance with current building codes for heating, ventilation and air conditioning (See KNAUF AutoCAD nodes below).
Humidity conditions of buildings and structures in winter period depending on the relative humidity and temperature of the internal air, it should be set according to table 1 of SNiP II-3-79* “Construction heating engineering”
Plasterboard sheets are available with various types of longitudinal edges
Sealing of gypsum board joints with edges of the UK and PLUK types is carried out using reinforcing tape.
The PLUK edge, in addition, allows you to seal 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.
The end edges are rectangular in shape.

Metal profiles KNAUF are manufactured in accordance with TU 1111-004-04001508-95 and are long elements made by cold rolling of thin steel strip with a thickness of 0.55-0.8 mm on modern equipment.
Standard profile length KNAUF is 2750, 3000, 4000, 4500 mm.
The maximum length of profiles is 9000 mm.
Rack profiles (PS) have a C-shape and serve as vertical frame posts intended for plasterboard cladding. The rack profile is mounted in pairs with a guide profile of the appropriate size.
PS profiles KNAUF Available in the following section sizes:
It is allowed to connect rack profiles along the length (1.073.9–2.00.1–9). When installing in areas of overlap, a rivet connection, a connection with LN9 type screws or using a cutter - the “notch with bend” method is used.
Guide profiles (PN) They are U-shaped and serve as guides for rack profiles, as well as for arranging jumpers between them in cladding frames. Mounted in pairs with a PS profile of the appropriate size.
Mon profiles KNAUF Available in the following section sizes:
(PNP 28×27) has a U-shape and serves as a guide for the ceiling profile, as well as for installing jumpers between them in the C623 cladding frames. Mounted in pairs with a correspondingly sized ceiling profile (PP 60×27).
Ceiling guide profile (PNP 28×27) is produced with ready-made holes F 8 mm in the profile wall with a pitch of about 250 mm. for attaching it to the supporting base.
Ceiling profile (PP 60×27) has a C-shape and serves as vertical posts of frames intended for cladding with plasterboard sheets. Mounted in pairs with a ceiling guide profile of the appropriate size (PNP 28×27).
Soundproofing and thermal insulation materials
As a soundproofing and heat-insulating layer in plasterboard cladding systems KNAUF products made of mineral and glass fiber with a synthetic binder and other materials included in the “List” should be used polymer materials and structures approved for use in construction by the USSR Ministry of Health" - M.1985 and having a certificate fire safety and a hygienic certificate for use in premises of the appropriate purpose.

Walls and partitions are considered an important element of any home. Without them, it will not be possible to divide the building into separate rooms. Particularly in demand today are Knauf partitions, which consist of a steel frame and plasterboard sheathing. This popularity is due to the excellent quality and affordable cost of the products. All its characteristics comply with European standards, and installation is so simple that anyone can handle it.
Advantages
Knauf partitions have found their application due to their advantages:
- ease and speed of installation (assembled element by element);
- ease of repair (the finished wall can be quickly disassembled and moved to another location);
- low cost;
- absence of “wet” processes;
- reliability and durability.
These partitions have also gained popularity among consumers due to other qualities:
- the ability to use the structure in regions with seismic hazard;
- high quality products;
- opportunities to lighten the building;
- general savings on construction;
- variety of architectural solutions (curvilinear forms can be built);
- the ability to obtain a structure with increased fire resistance, sound insulation, and moisture resistance;
- environmental friendliness;
- variety can be covered with paint, wallpaper, decorative plaster).
Installation of partitions “Knauf”
As stated above, this system consists of plasterboard panels, internal filler and fasteners. Additionally, it can be equipped with specialized plates that have increased fire protection. The covering can be one-, two- or three-layer. In this case, plasterboard, hyposavo fiber or aqua panels are usually used.
As for them, they come in guides, rack-mounts and load-bearing types. Together they form a frame, with each element having a standard length of 3 or 4 meters.
If necessary, the profiles can be lengthened by overlapping them. They are fastened with self-tapping screws: four on each edge and two in the middle. External side the guide element is covered with insulating tape. Self-tapping screws are placed on it every 300 mm (maximum pitch - 1000 mm). TO load-bearing structures the partitions are secured with dowels.
Varieties
Depending on the purpose and device, Knauf partitions are divided into types: W111, W112, W113, W118. The W111 system is a frame covered with single-layer material on both sides. Sound insulation is placed inside it. The guides are attached to the supporting structures using dowels. After attaching the drywall, the joints between the sheets are filled with a special compound.
The W112 partition includes a frame, two layers of sheathing on both sides and sound insulation between them. The structures are also fastened with dowels, but additional fixation of the second layer of sheathing is necessary. This has a positive effect on fire resistance and sound insulation.
The W113 structure consists of a frame and three layers of skin (on both sides). There is non-flammable sound insulation inside. Such a wall has serious cladding, so it must be fastened at a maximum interval of 50 cm.
The W118 partition has the same structure as the previous design, but it is reinforced with a galvanized sheet 0.5 mm thick. It is also equipped with a reinforced profile frame, 0.6 mm thick. The article presents drawings of Knauf partitions and how they are attached.
Profile types
Depending on the purpose, Knauf profiles are divided into rack-mount, guide and arched. Rack structures have a cross-section in the shape of the letter “C” and are located vertically in the frame. The racks are installed together with guide profiles of the appropriate size. The ends of the products are equipped with two holes through which utility lines are laid (hidden in the walls). They are attached to the guides with self-tapping screws, which are easily centered thanks to the longitudinal grooves.
They have a cross-section in the shape of the letter “P” without curved edges - this allows you to get a tight fit of the racks to the upper and lower elements. They are needed not only for fastening rack parts, but also for installing jumpers between them. During manufacturing, holes are drilled in the structures into which dowels are inserted during installation.
Partitions “Knauf”, technical specifications which are listed in the table below, can also consist of arched profiles that serve as the basis for curved structures. They are made of different radii, and the shelves can be wrapped inward or outward.
Cladding options
During installation, structures can be sheathed different types plasterboard sheets. The sheathing is attached to metal profiles and can have 1, 2 or 3 layers. This is necessary when the building is subject to deformation loads.
Conventional plasterboard is used in rooms with normal humidity and differs from other types gray. The composition includes protective additives that make the material “breathable”. When manufactured, it is painted green.
Special additives are added to fire-resistant sheets that are not subject to combustion. The material is different pink. Combined gypsum plasterboard combines the properties of fire-resistant and moisture-resistant types. It can be recognized by its green coloration with red markings.
Knauf partition installation technology
There is nothing complicated in this process, but it is important to know some rules and nuances. First you need to prepare the walls, floor and ceiling. They will need careful alignment so that the guides fit without distortion. The next stage is applying markings, the evenness of which is checked by a level, a cord and a plumb line.
After preparing the base, begin installing the profiles:
- Install load-bearing elements and attach them with dowels (pitch - 200-400 mm).
- Have vertical structures, which are located at equal intervals (corresponding to half the width of the plasterboard).
- They are attached with self-tapping screws.
- Lay the horizontal guides so that they define two identical planes of the future partition.
- The frame is secured using a cross and special screws.
The result should be a frame with square cells 600x600 mm.
Insulation and plasterboard covering
Installation of the Knauf partition also includes laying a soundproofing layer. Most budget option allows you not to use additional materials, however, if necessary, you can put foil-based insulation or mineral wool inside the frame.
After installing the frame, laying insulation and engineering communications You can start attaching drywall. For these purposes they are used special screws. You should know that joining sheets can be done arbitrarily, but it is preferable chess order. Thanks to this, there will be no cracks in the structure and a stronger connection will be obtained.
Partitions “Knauf” - designs with original elements, characterized by durability and high quality. Their use will allow you to erect a small building in a short time.
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 frame 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 external coating of frame structures KNAUF company produces durable high-tech gypsum-based material that does not contain toxic substances, absolutely non-flammable and has excellent performance 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 application, these sheets have various 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
The following components of 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 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 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 a step-by-step technology for installing plasterboard systems, implying a strict sequence of all work. So, let's look at brief instructions for installing a plasterboard partition:
- 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.
- Installation of equipment. 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 brief overview plasterboard systems developed by the famous 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. Rest assured, we will give you an answer that will provide a “pleasant” result in such a difficult task as home renovation.
