Application area

Application area

It is used as internal enclosing structures in rooms various types, with dry and normal humidity conditions according to SNiP 23-02-2003, residential, civil and industrial buildings of all degrees of fire resistance and erected in any areas, including seismic ones.

It is applied both at reconstruction, and in new construction.

The most versatile 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 an insulating material made of mineral fibers.

The surface is intended for subsequent finishing, such as wallpapering, painting, tiling, etc.

Mounting process includes the following stages of work.

Marking the design position of the partition on the floor, ceiling and base walls.
Installation of partition frame C 112.
Installation of electrical wiring and embedded parts for fixing stationary equipment inside the frame.
Installation and fixing on one of the sides of the frame of vertically oriented KNAUF plasterboard sheets (GKL).
Installation and fixing on the frame of the second layer of vertically oriented KNAUF plasterboard sheets (GKL).
Sealing joints between KNAUF plasterboard sheets (GKL).
Fastening in the space between the racks insulating material if provided by the project.
Installation and fixing of KNAUF plasterboard sheets (GKL) on the other side of the frame.
Sealing joints between KNAUF plasterboard sheets (GKL).
Installation and fixing of the second layer of KNAUF plasterboard sheets (GKL) on the other side of the frame.
Sealing joints between KNAUF plasterboard sheets (GKL) and priming the surface for decorative finishing.
Decorative finishing of the partition after the device of the finishing floor.

Partition walls should be installed within finishing works(V winter time with connected heating), before the installation of clean floors, when all the "wet" processes are completed and wiring of electrical and plumbing systems is completed, in dry and normal humidity conditions in accordance with SNiP 23-02-2003 "Thermal protection of buildings". In this case, the temperature in the room should not be lower than 10°C.

In conditions of high humidity (bathrooms, kitchens, bathrooms), it is recommended to use moisture-resistant KNAUF gypsum plasterboard sheets (GKLV), while it must be borne in mind 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 the sharp edges of the frame elements or screws during the fastening of Knauf plasterboard sheets (GKL).

in repair and construction work applicable . This construction material has a flat surface, so you can easily create, as well as with the help of 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 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:

Considering everything Knauf features, we can say with confidence - its service life is long.

The names of the elements of the Knauf partition

Installation of partition C112

The partition wall installation technology is carried out in compliance with step by step instructions. Start off installation work should be carried out when all work with electricity and is completed. After graduation repair work with flooring, as well as the end 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. For profile cutting desired length scissors are used to cut metal.
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 up 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.

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 quality materials required in the performance of such work and is a kind of legislator that defines 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 carcass and 2 layers of sheathing from GKL 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 - partition frame made of wooden beam sheathed with 1 layer of plasterboard.
	From 122 - 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 various 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. IN frame structure install embedded elements (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 short review 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.
