Knauf installation technology. Well-known Knauf technology and drywall: walls and partitions using a new method

German Knauf company has long been considered a European and world construction standard, and the set of measures, which in our country is called European-quality renovation, is based on the achievements, materials and technologies obtained thanks to the developments of this particular company.

Without going too much into historical digressions and amendments, just for the sake of interest, I would like to note that this company, which began as a family business in Bavaria, represents its products in almost 40 countries around the world. And the total number of enterprises of this corporation of “monsters” (in a good and business context) has long crossed the 200 mark. Now let’s leave the historical and statistical calculations and move on to more practical things - technology.

Basic principles of technology and policy

Thanks to its principles, mixed with German quality, the company quickly became a leader: it is considered and its opinion is listened to all over the world. It is not for nothing that Knauf has practically no full-fledged competitors on the world market.

This success is based on two basic principles:

Offer consumers only proven and high-quality materials;
Carry out the repair and construction process strictly in accordance with the stated technologies. For this purpose, training of plasterboard masters is carried out on the basis of specially created training centers.

The company meticulously pays attention to all the details. Considering that they cannot exist as such, everything is important.

Let's start with the basics

Installation instructions plasterboard Knauf begins with covering the issues of selection of materials and tools. It is clear that the company tried to declare its products, but as they say, it has the right to do so.

There are four main types of plasterboard sheets:

Regular plasterboard sheets, are intended for interior decoration of premises for which there are no special requirements: living rooms, cabinets, offices;
Moisture-resistant plasterboard sheet, which has a direct path to bathrooms, kitchens and other interior spaces where there is high humidity;
Fireproof plasterboard, or special, is used to hide heating routes in rooms, as well as to hide electrical wiring, especially general wiring lines;
Combined fire and moisture resistant sheet. No additional explanation or introduction is needed.

For your information! For the convenience of sellers and buyers, each sheet of drywall has its own color and markings. In domestic use, the most popular and frequently purchased are ordinary plasterboard sheets and moisture-resistant plasterboard sheets, sheet thickness 12.5 mm for walls, and 9 mm for ceilings

Metal profiles. Their purpose is to construct a frame on a ceiling or wall in order to install plasterboard sheets in one plane. At the same time, it is allowed, and sometimes encouraged, to create multi-level structures on the ceiling according to individual projects, as well as the construction of built-in furniture, niches, supporting or zoning structures. Here, too, the leading profiles are of four types:

Ceiling CD profile is used to create lathing on the ceiling;
Guide ceiling UD profile, a profile with which a single (base) level is established for the entire ceiling structure, placed along the perimeter of the walls as close as possible to the ceiling (if it does not concern raster variations, with a deliberate reduction in the ceiling level);
Rack-mounted CW profile, similar to the ceiling CD. It is from this that the frame of the wall sheathing is formed, and it also takes an active part in the creation of built-in niches, false walls, and partitions;
Guide for CW profile UW profile. Analogue of UD for use in wall structures, the directions of application are the same as for CW.

Connecting and extension elements, mounting options:

The suspension is straight, universal, and difficult to replace, 120 mm. This is a really worthwhile invention, designed for attaching profiles to stationary walls and ceilings, installation is done with metal screws, the protruding parts are bent inward. By the way, the suspension is the leader in the number of popular names;
Extension of ceiling profiles CD-60. The main purpose is to cover the entire length of the room.

For your information! The Knauf drywall installation technology involves the use of exclusively “native” parts described in this subsection.

Well, we inform lovers of pure experiments that, of course, technologies exist and they must be followed. And for practitioners, everything described in this paragraph can be perfectly replaced with fragments of the UD-27 profile. The only thing that will be technologically more difficult to replace is direct suspension.

Single-level crab connector, cross connection for CD ceiling profiles. In this design, the overlay occurs on the main CD profile, and the side profiles are represented by trimmings of the required length;

Two-level ceiling connecting element. The purpose of this design is to join the sheathing parts when approaching the profile near a natural obstacle. T-joint;
Suspension for raster and suspended structures is designed to significantly lower the ceiling level. Gift raster designs. One suspension can support up to 25 kg of ceiling weight.

Putties and primers. Everything is simple here, despite the variety of specimens presented, they can all be grouped. And then we get the following:

Putty for joints based on alpha gypsum, with or without additives;

Starting putty for finishing plasterboard surfaces;
Finishing putty, used for final finishing of the same surfaces, the main difference from the previous putty is the size of the fractions;
Knauf deep penetration primer. The purpose of the application is to impregnate the material with leveling the layer and preparing it for painting or finishing with wallpaper, tiles or decorative tiles.

Tools. Quite a lot of attention was paid to this point and there is no particular need to repeat ourselves by listing the entire set, but in order to refresh our memories, let us remind you that there are tools:

Mandatory - their set can be easily calculated independently, based on the operations for which they will be used. Namely, cutting and cutting plasterboard sheets, cutting metal profiles, joining profiles and hanging plasterboard sheets and their fragments on the sheathing;
Additional is the so-called professional add-on, which will allow you to carry out drywall work without any problems, provided that this work relates to your professional activity. In this case, you will need:
A spacer lift that allows you to do the work yourself without help;
Laser level for “zeroing” the surface level;
The staple profile is not an essential tool, but it allows you to connect profiles together without screws; it can also be used to connect any soft metal products, for example, when working with galvanization;
A profile cutter is a craftsman’s tool, the purpose of which is to punch a hole in a structure for laying an electrical wire;

Roughing and edge planes are designed exclusively for working with drywall, one removes scraps of cardboard that are obtained when cutting the material, the second prepares the joining edge for joining at 45-degree angles;
A needle roller is a tool for applying defects to a plasterboard sheet in order to give the surface a curved shape. Used when working with the “wet” method.

KNAUF plasterboard is one of the highest quality and most sought-after materials on the construction and finishing materials market. More on the basic principles of working with KNAUF drywall, components and other useful details.

IMPORTANT! Drywall and components from KNAUF are often compared with similar products from VOLMA, citing the low cost and quality of domestic plasterboard. If you have a choice, KNAUF or VOLMA, you should proceed from the expected budget and the type of structure being performed (not all structures can be built using VOLMA products; KNAUF has a wider range of materials application).

Knauf plasterboard: sheet processing and the tools necessary for this

When working with drywall, one of the main conditions for quality work is the choice of materials and components from one manufacturer.

Drywall KNAUF: tools and materials for work

To cut drywall, use a utility knife, a hacksaw or a toothed saw, a graver or a round cutter, and an inch ruler.
To putty the joints of plasterboard sheets, use KNAUF Fugenfüller putty.
To putty drywall, it is recommended to use a universal spatula, a spatula-screwdriver, a trowel, a wide spatula and a sanding machine.
For puttying drywall - with a trowel, mixing container, mixing attachment or mixer.
The grooves for installation can be marked and cut by hand. The second option is to make them with a gravel or a special cutter for round holes.
For correct marking drywall using a water level, a marking cord and a tape measure.
For fastening drywall - with a self-tapping screw or screwdriver.

How to cut a sheet

To cut a plasterboard slab, turn the sheet over with its front side facing you and cut it according to the markings using a utility knife and a strip or metal bar. Then the sheet is broken along the edge. All you have to do is cut through the cardboard from the back.

IMPORTANT! After cutting any sheet of drywall, if it is intended that the sheet will be cut into a joint with another sheet, it is necessary to chamfer it at an angle of 45° using a plane.

Correct installation of KNAUF drywall

Knauf plasterboard, depending on the type of structure and its purpose, can be attached to an existing one monolithic wall with glue (ceiling plasterboard is attached only to frames), or installed on a metal frame. If it is necessary to divide the room, you can use KNAUF partitions with racks: install KNAUF, and then cover it on both sides with sheets of plasterboard.

Photo 2 - Wall covering with KNAUF plasterboard boards

The method involves fixing plasterboard slabs to the walls using glue. This method can only be used with slight curvature of the walls (up to 4 mm).

In this case, material is laid between the wall and the plasterboard slabs along the frame for additional sound or heat insulation of the room.

IMPORTANT! For wall coverings, plasterboard thinner than 12.5 mm is not used. If the wall covered with plasterboard is subsequently planned to be covered ceramic tiles, you will need to cover not one, but two plasterboard slabs.

Correct installation technology

Drywall boards should be fastened to a metal frame or a frame made of wood using Knauf self-tapping screws. Fastening the sheets should begin from the center of the gypsum board or from the upper corner to avoid deformation of the slabs. It is important that the screw attachment NK 11 is used, ensuring that the screw head is properly immersed in the sheet of drywall (necessary for finishing puttying of the sheet).

In order for you to end up with an optimal seam, plasterboard KNAUF slabs should be installed end-to-end, without gap.

There should be no cross-shaped seams during the installation process. That is, the end edge of the drywall sheets should have a slight offset - by the distance between the posts, the so-called axial distance.

Plasterboard sheathing: correct fastening with screws

The distance between the screws when covering walls should be 25 cm, when working on ceilings with KNAUF plasterboard - 17 cm.

Sheathing screw length metal structure We calculate based on: thickness of the gypsum plaster board +1 cm.

Sheathing screw length wooden structure: gypsum board thickness + 2 cm.

Technical characteristics of KNAUF sheets using the example of moisture-resistant plasterboard

Cardboard color is green.

Edge type - PLUK (semicircular thinned edge).

Main dimensions, mm − 2,500/1,200/12.5 ( standard sheet for floors and interior partitions).

Weight of GKLV KNAUF (2,500/1,200/12.5 mm, 3 m²) - 29 kg.

Geometric parameters of GKLV KNAUF

length - from 2,000 to 4,000 mm (and in increments of 50);

width - from 600 to 1,200 mm;

thickness (depending on the length of the sheet) - 6.5; 8; 9.5 mm (for sheet lengths up to 2,000 mm), 12.5; 14; 16 mm (for sheet lengths up to 4,000 mm), as well as sheets on special order with a thickness of 18; 20 and 24 mm.

Technology of covering a brick wall with KNAUF slabs

When working in a medium-sized room, it is necessary to prepare about 30 kg of Knauf Perlfix. The dry mixture is poured into a container with clean water(volume about 17 l) and stir until smooth.

The plasterboard slabs are cut, after which the Knauf Perlfix solution is distributed along the back side of the sheets with marks in increments of 35 cm. The distance to the edges should be at least 5 cm. And also apply a series of clumps along the longitudinal axis of the sheet.

The slabs are placed in a vertical position and pressed against the base of the wall, leveling.

IMPORTANT! Perlfix sets in about 10 minutes. During this time, the slabs are adjusted to the level using a rubber hammer and a block.

Alignment of walls on a frame basis to improve sound and heat insulation

Knauf UD profiles are cut to size using metal scissors.

IMPORTANT! To ensure better sound insulation, before attaching the UD profile to the floor and ceiling, a special KNAUF self-adhesive soundproofing tape is applied to the profiles.

Knauf UD profiles are attached to the floor and ceiling at the above distance from the main wall using Knauf K6/35 dowels. In this case, the maximum distance between dowels should be no more than 1 m).

IMPORTANT! Sound insulation can be improved by leaving a distance of 50 mm or more between the front edge of the frame and the existing wall.

To support the CD profile in the middle of the height of the walls (taking into account the fact that the maximum permissible distance is 1.5 m), direct KNAUF hangers are attached to the wall using pin dowels, with soundproofing tape laid in them in advance.

CD profiles 60/27 must be installed with a pitch of 60 cm vertically in relation to the UD profiles, after which the fasteners must be connected with screws. Direct hangers are also attached.

Install Knauf plasterboard sheet insulation. Now you can start fixing the sheets themselves to the frame using self-tapping screws (maximum distance between screws is 25 cm).

The axial distance between CD profiles for vertical sheathing with plasterboard sheets is: if the width of the plasterboard board is 1,200 mm, the axial distance is 60 cm.

You can buy Knauf plasterboard in almost all major construction supermarkets in the country.. On sale you can find both standard and moisture-resistant gypsum plasterboards; you can also order perforated acoustic plasterboard from the warehouse to increase the sound insulation of a room, or fire-resistant plasterboard to organize passive fire protection in rooms with a high probability of an open flame.

Alfons and Karl Knauf are brothers. Both were educated as mining engineers and, due to the nature of their activities, became particularly interested in the natural material – gypsum. Having studied its properties, they decided to use them in order to speed up, reduce the cost and improve the quality of some construction processes.

The implementation of their project fell on time economic crisis. It’s as if time itself was helping the future bigwigs of the construction industry. In 1932 they founded the company "Reinische Gipsindustri und Bergwerksunternemen".

Having collected Required documents and having received an indulgence to develop a gypsum mine in Schengen, the brothers opened a plant in the city of Perl. They began to produce dry construction mixtures based on natural gypsum for plastering surfaces.

In 1949, in the city of Iphofen, which is located in Northern Bavaria, the Knaufs established a plant for the production building mixtures based on gypsum. The headquarters of the Knauf company are currently located here. In 1958, they opened the first plant for the production of plasterboard sheets.

During the years of German economic prosperity, the company developed rapidly and from a relatively small enterprise turned into a family with subsidiaries around the world. In 1993 they began their activities in Russia. Many enterprises are opening across the country, equipped with modern equipment, using uniform production technology and quality standards.

Knauf products

But Knauf does not rest on its laurels, the company is developing new projects and offering the consumer:

palette of related products. The range is expanding due to specialized tools, metal profiles, development of new materials;
building mixtures not only based on gypsum, but also other innovative compositions;
Special courses are conducted where theoretical training is carried out. Those who wish to acquire practical skills in construction and design.

Knauf enterprises produce high-quality finishing materials:

gypsum fiber sheets;
tongue-and-groove gypsum boards;
dry gypsum and cement mixtures;
primers, other compositions for interior finishing, ready for quick use;
construction chemicals;
metal profiles;
plasterboard sheets.

We will focus on the last two groups of products and tell you what drywall and Knauf profiles are, about production characteristics, dimensions and installation.

Types of Knauf drywall

The products manufactured by this manufacturer are used to perform work on interior decoration"dry" method. It's practical and fast. Drywall sheets are classified according to their properties:

ordinary, some builders also call it standard,
moisture resistant
refractory.

Regular drywall

A sheet of ordinary (standard) plasterboard is used in rooms where natural temperature conditions and normal humidity are maintained. They can be used to veneer interior walls residential premises, offices, enterprises.

Standard sheets according to external sign differ from other species in color scheme– have grey colour and blue markings. They are not expensive and are used much more often than others.

Having studied its characteristics, we talked about them in detail in the article “”, we can state that such a sheet:

not dangerous for people and the environment;
helps to radically change the space and interior of the room. With the help of such a sheet, a partition, arch, or fireplace can be quickly erected;
it is perfectly lined with any finishing materials: plaster, tiles, wallpaper, paint, stone;
It is easy to cut and takes the required configuration.

When you plan to make repairs in your home and change the contours of its premises, you can use the following Knauf plasterboard sheets for the walls:

Moisture-resistant gypsum board

Sheets of moisture-resistant plasterboard should be used where high humidity is expected or the room is poorly ventilated. The technical characteristics of the sheet make it possible to install additional partitions and improve the walls:

in the shower, bathroom;
in swimming pools and saunas;
in toilet rooms;
in sanitary facilities.

For these jobs it is better to use Knauf sheets shown in the table below:

The color of the leaf is green and has blue markings.

Fire-resistant plasterboard sheets are used where the temperature is high and safety precautions must be strictly observed. fire safety. Technical characteristics of the named finishing material they say that they can:

cladding the walls of wooden buildings;
carry out installation in domestic boiler rooms, furnaces, sanitary premises of enterprises;
decorate fireplaces;
line the walls of evacuation exits.

For these purposes, Knauf offers the following sheets:

GKLO differs from other types by its pink color and red markings.

Now that you know what types of drywall there are, its sizes, specifications, insignia, you can proceed to the next section and find out how to install sheets to a vertical surface.

Metal frame elements

All metal profiles at Knauf factories are manufactured in accordance with the conditions TU 1121-012-04001508-2011. These are elements of a certain length, made of steel strip using the cold rolling method on modern roll forming machines. They are galvanized to protect them from aggressive environmental influences.

With the help of such structures, a frame for sheathing is assembled; they serve as a rigid base, on which plasterboard sheets are then laid.

Profiles have standard lengths: 2750, 3000, 4000, 4500 mm. But at the request and agreement with the customer, their height can vary from 500 to 6000 mm.

Work on cutting and assembling metal products is carried out using specialized tools, such as electric shears, cutters, a hacksaw or other devices.

The following structures are required for the frame:

rack profile. By appearance looks like the letter “C” and acts as vertical posts of the future frame. Mounted in conjunction with a guide profile. You can learn about its geometric dimensions from the article “”;
guide profile. This part is a P- figurative form. In the frame it functions as a guide for the rack profile and is used for installing jumpers.
ceiling guide profile. It has the shape of the letter P. It is necessary in the frame as a guide for the ceiling profile and for mounting the lintel over the opening;
ceiling profile. Presented in the form of a C-shaped long part, it performs the function of a vertical frame post. To attach it to the wall, a direct suspension is used, which can be secured with screws;
screws and dowels are used as fasteners, which are described in detail in the article “”;

Installation of gypsum boards on walls using Knauf technology

Knauf brand plasterboard sheets are quite popular material on the Russian construction market. The technology of their installation has a significant advantage over other facing building materials.

The absence of so-called wet processes during operation significantly reduces time and installation becomes easier. With minimal labor and money costs, a perfectly flat surface is achieved.

Designers had a unique opportunity to realize their most daring projects. And the technology for laying sheets is so simple that it can be done by a person far from construction.

It is worth remembering that installation work must be carried out under normal humidity and temperature conditions.

Methods for installing drywall on walls

You need to know that gypsum board can be installed in two ways, each of them has its own technical differences:

frameless method. In this option, the sheet is simply glued to the base. But you should know that the area to be treated must be very flat and always clean;
using a frame. It can be presented in the form of a structure made of lumber and metal. The wooden one will cost a little less, but it is not as convenient to use and is not durable. And here is a set of metal profiles Knauf company widely known and popular among specialists and amateurs. All parts are produced at the plasterboard manufacturer and have a relatively low price.

We will dwell on this technique in more detail, reveal its technical aspects and give recommendations from the manufacturer.

By Knauf technologies the entire process should include the following steps:

Frame preparation;
Its installation;
Covering the frame with sheets;

Installation work should begin before the installation of a clean floor, provided that the plumbing, technical and electrical systems have been installed in the room. Temperature not less than +10 °C and humidity must be normal, these are mandatory requirements according to SNiP 02/23/2003. If winter time– the building must be heated.

This technology makes it possible to insulate a room without any problems, improve its sound insulation, lay and hide communications, and create various structural elements.

Required tools for installation

Each specialist has a certain minimum of tools and equipment. We recommend you standard set, which you can’t do without:

building level, plumb line, hydraulic level;
screwdriver, hammer drill;
metal scissors, electric scissors, grinder;
mounting knife;
a simple pencil;
roulette;
a thread;
sealing tape.

Installing a metal frame on the walls

This profile is more durable and reliable. All its varieties are produced at Knauf industrial plants and comply with standards. The installation process undergoes quality control at all stages of work: first after installing the frame, then after laying drywall, then installing joints and seams.

Let's mark the floor surface and then transfer it to the ceiling and walls. In order to carry out installation without errors, experts recommend marking the attachment points of the rack profiles, the type and thickness of the gypsum board.
On the rack and guide profiles adjacent to the enclosing structural elements, it is necessary to stick a sealing tape or apply a special sealant composition. Install guide profiles according to the markings and then screw them to the horizontal surfaces of the floor and ceiling. The pitch should not exceed 1000 mm, and there should be at least 3 fasteners per profile.
According to the marking marks, fasten straight hangers to the wall using appropriate dowels. The pitch is no more than 1500 mm. To weaken the “sound bridges”, place sealing tape between them.
We install the profiles in the guides and secure them with screws. Interfering ends of the hangers should be bent or cut off.

Laying drywall on a metal frame

This technology is:

We start working from the corner with a screw pitch of 250 mm. They should be no closer than 15 mm from the edge of the transverse end, and 10 mm from the longitudinal end. If you have to double cover the surface, it is allowed to increase the step by 3 times. It is better to start from the corner of the big wall premises.
Drywall is laid on the walls in a vertical direction and in whole sheets. Small fragments are filled in later. If there is a difference between the heights of the wall and the gypsum board, and the latter is smaller than the first, then sections of the guide profile are added to the horizontal joints and then the gypsum board is sheathed.

The sheets are joined in a staggered manner. Avoid joints where window mullions are or where a drywall doorway is. As a result, a crack will definitely appear in this place. It is better to pre-install the intermediate profile and additionally fix the sheet.

The heads of self-tapping screws or screws must be well recessed into the surface by 1 mm or more. After puttying there will be no depressions on the surface.

Points that should not be forgotten when installing gypsum boards on walls

Do not forget to leave a gap of 10–15 mm high between the gypsum plasterboard and the floor, and 5 mm at the junction with the ceiling. Subsequently, it will be covered with a putty solution and taped with a separating tape, the edges of which will then be carefully cut off.

External joining corners can be reinforced with a protective perforated corner. finishing it will be completely covered with putty.

Where the sheet meets the door or window boxes, decorate its edges decorative trims when you do the finishing touches.

For moisture-resistant plasterboard sheets, screws with a sharper conical head are used. The pitch is no more than 300 mm.

If there is a need to hang a hundred or on the wall, then know that with a weight of no more than 10-15 kg per 1 linear meter wall surface, it can be secured using special anchor bolts for gypsum boards or dowels for gypsum boards anywhere. These may not be heavy openwork shelves, cornices, paintings, sconces or others lighting. But if you plan to exploit kitchen cabinets, then it is necessary to install additional embedded parts in the places of future fastening. Specialists should take care of this during the installation process. metal frame.

As soon as your walls have received a new look, you should begin to putty, process the joints and places where the screw heads are located.
But we will talk about this in the article, which will be called “;”.

Distribution internal space In a house or apartment, dividing rooms into rooms today is most efficiently and quickly accomplished by installing plasterboard partitions using KNAUF technology. Application modern materials allows you to assemble internal structures of any complexity in any operating conditions. The main advantages of the technology are rapid installation, high degree constructiveness and soundproofing properties through the use of fillers.

The partitions are frame structure with double-sided lining sheet plasterboard and filling soundproofing material. They provide for the installation of sockets, electrical and low-current wiring, internal pipeline fittings. The structures are designed for use in both dry and wet areas, as well as for hanging furniture and resistance to mechanical stress.

Features of the partition

Depending on the conditions and architectural features of the room, different requirements are imposed on the partition. The main criteria to build on are:

dry or damp room;
ceiling height;
probability of mechanical impacts;
fire safety requirements;
the need to hang furniture or equipment.

Choosing drywall

GCRs vary in thickness and specialization. In terms of thickness - sheets for frame (12.5 mm) and frameless (9.5 mm) installation. Since the partition is made on a frame, you should choose plasterboard with a thickness of 12.5 mm.

9.5 mm sheets are designed for adhesive mounting or sheathing old surface with support on the entire plane. At the same time, dividing plasterboard into wall and ceiling is erroneous.

According to their specialization, gypsum plasterboards are divided into standard, moisture-resistant, impact-resistant and fire-resistant.

The moisture-resistant material is used in wet rooms - bathrooms, swimming pools, bathrooms, kitchens, etc.

Impact-resistant is used when there is a likelihood of mechanical impacts provided for by the purpose of the room, for example, gyms, children's rooms. Due to its increased strength, such plasterboard is also used for the construction of structures 8 m or more in height. Fire-resistant HA is used in rooms with increased fire safety requirements, as well as for lining areas where it is planned to install a stove, boiler or electric heating devices. Standard ones are cheaper and are great for dry residential and public spaces.

Double or single layer sheathing

Covering the frame with HA sheets can be done in either one or two layers. An ordinary partition that does not perform load-bearing functions is made with single-layer cladding. If it is necessary to hang any equipment, furniture on it, or to cover it with massive ceramic tiles, the sheets are mounted in 2 layers.

If it is intended to use impact-resistant sheets with two-layer sheathing, the first layer can be made with simple plasterboard. It is also possible to implement a “warm wall” using IR heating film. In this case, the film is mounted on the first layer of HA, and the second layer can be applied in sheets 9.5 mm thick.

Selecting Profiles

Galvanized PN profiles with a base of 50, 75 or 100 mm and a shelf width of 40 mm are used as guides. Rack-mounted - PS must correspond to the guides, so they have a corresponding base width that is 2 mm smaller with a shelf width of 50 mm. All KNAUF profiles have a wall thickness of 0.6 mm, which differs from products from other manufacturers with a wall thickness of 0.4 mm.

The choice of size is made depending on the height of the partition and sound insulation requirements. For a height of up to 3 m, it is enough to use a profile with a width of 50 mm, from 3 to 5 m - 75 mm, and over 5 m - with a width of 100 mm. Naturally, the wider the frame, the greater the distance between the walls will be, and, therefore, the thicker the sound insulation layer. Therefore, if the requirements for sound insulation performance are increased, then even for standard height 2.5 m partitions, profiles should be chosen wider.

Frame installation

The assembly of plasterboard partitions using KNAUF technology begins with the installation of the frame. This part of the structure will be hidden and, if mistakes are made, the entire structure will have to be dismantled. Therefore, this stage must be taken with complete seriousness and compliance with all rules.

Marking

Marking the structure should begin from the floor. To draw a straight line you need to measure extreme points and pull a thread between them. You can transfer the markings to the walls and ceiling using a plumb line. The partition installation lines are marked with a pencil on all 4 planes (walls, floor and ceiling).

Professionals use a laser level for these purposes, which speeds up and simplifies the process. You also need to mark the location of the doorway, marking it on a line drawn on the floor.

Installation of guides

Before installing the guide elements, sealing tape must be applied to the sides adjacent to the walls of the floor and ceiling. This will reduce sound transmission and prevent cracks in the finish.

The profiles are set at an angle between the base and the shelf along the marked lines. Fastening to the floor and walls is done with plastic dowel-nails, and to the ceiling - with metal anchor dowels. Guides on the floor are not installed at the doorway location.

Installation of racks

Based on the standard width of gypsum boards - 120 cm, the racks are installed in increments of 40 or 60 cm so that each sheet rests on vertical profiles along the edges and in the middle. Required amount the racks are cut so that their length is 1 cm less than the ceiling height. This is done for ease of installation and compensation for the deflection of the ceiling, as well as seismic loads.

Then the racks are inserted into the lower and upper guide profiles with shelves in the direction of installation of the drywall and are aligned strictly vertically. Verticality is verified using a leveling rod. Immediately after alignment, the stand is fastened to the guide using a cutter.

Installation of doorway profiles

Taking into account the massiveness of the doors, as well as the dynamics during their operation, a reinforced UA profile with a wall thickness of 2 mm is used for the doorway. According to the marking of the opening, 2 sections of UA profiles are aligned vertically into the guides and through them secured to the floor and ceiling with dowels using special adjustable brackets. The upper contour of the doorway is limited by a horizontal section of the PN profile, fixed in the same way as lintels.

Often they use 2 rack profiles inserted into each other in the form of a box, but this is not enough for the weight of the door and the dynamics of the loads.

Installing jumpers

The jumpers are made from a guide strip and installed in a horizontal position between the racks at the calculated locations of the horizontal joints of the GC sheets. To do this, a profile is cut 20 cm longer than the distance between the posts. Then 10 cm is measured on both sides and the shelves are cut at an angle of 45° from the intended line to the edges of the shelves. After which the edges are bent at right angles. In each horizontal line, jumpers are mounted alternately, alternating with bent ends up and down.

Thus, the bent parts are put on the racks and do not interfere with each other. The jumpers are also secured using a cutter. When the frame is installed, a dividing tape is glued along the junction with the ceiling in order to prevent the appearance of cracks in the corners.

Installation of gypsum boards

Installation of drywall is carried out in conditions of relatively constant humidity, so work should be planned after completion of all wet processes - pouring screed, plastering and drying. After delivering the HA sheets to the installation site, they must be kept for 24 hours to acclimatize (even out the humidity). During this time, the material is stored in a horizontal position without direct contact with the floor. In an inclined position, the sheets may become deformed.

Sheathing of the frame starts from the bottom with a distance of 1 cm from the floor. Based on the standard sheet length of 250 cm and the height of the ceiling, as well as taking into account the gap between the bottom end and the floor, it is necessary to calculate the height of the required section of gypsum board under the ceiling. According to the Knauf plasterboard installation technology, it is not allowed to use sections shorter than 40 cm, so if, as a result of the calculation, this size turns out to be smaller, then installation must begin with half a sheet. All horizontal ends are processed with a special edge plane, with a chamfer angle of 22.5° to a depth of 1/3 of the thickness. For installation bottom sheet you need to prepare linings 1 cm thick to maintain the appropriate distance from the floor.

Installation is carried out staggered so that the horizontal joints do not coincide along the same line and are spaced at least 40 cm in height. The sheets are fastened to the frame using TN 25 screws in increments of 25 cm. The screw is screwed in with a distance from the end edge of at least 15 mm and from the longitudinal edge - 10 mm. The screw must penetrate into the frame to a depth of at least 10 mm, and the head must be recessed by 1 mm. The sheets are not attached to the guides on the floor and ceiling.

For plating doorways the vertical joint should not be in line with the opening, so an L-shaped cutout is made in the sheathing material.

After covering one side of the partition, mineral heat and sound insulation is placed in the cavity between the walls. It should be laid tightly against the frame elements without gaps. Roll or slab material is selected according to a thickness equal to the distance between the walls.

The wiring is then pulled through the structural holes in the racks. If necessary, you can drill additional holes in advance and process their edges so as not to damage the insulation of the wires. After this, you can begin covering the second side using a similar technology.

Upon completion of the installation of drywall, holes are drilled in the designated places using an annular cutter for installing sockets.

It is more convenient to install sockets opposite each other on both sides of the partition. This saves wiring but reduces soundproofing properties partitions, so it’s better to do it right and install adjacent sockets with a horizontal offset of 10-15 cm.

Putty joints

Vertical and horizontal joints are treated with a primer 3 hours before puttying. The seams are sealed with high-strength gypsum putty in 2 stages. First, the joints are covered with putty. Immediately apply a paper reinforcing tape over the fresh solution, lightly pressing it in with a spatula. The corner joints of the partition with the wall are reinforced with perforated corner profiles. The covering layer is applied to the seams only after the first layer has completely dried. In the case of two-layer sheathing, the joints of the first layer are puttied without reinforcing tape.

Finishing

The formed partition plane is a rough surface and is subject to facial finishing. Wallpapering, painting with water-based paints or tiling can be used as cladding.

In any case, the entire surface will have to be puttied and leveled to the level of the seams. Before puttying, it is advisable to treat the entire surface with a primer, and after it dries, putty the screw heads.

Wallpaper

The putty is applied in a thin, even layer. The starting layer will be sufficient for subsequent wallpapering with preliminary priming with wallpaper glue according to the manufacturer's instructions.

Painting

To paint the wall must be brought to perfect condition. To do this, a finishing gypsum solution is applied over the dried starting layer. After drying, sanding with a float and the obligatory primer are carried out. If you neglect the primer before painting, the paint on the seams and between them will be absorbed unevenly, resulting in stains.

Tile

For facing wall tiles, an ideal surface is not required and you can limit yourself to only a starting layer of putty. It should be borne in mind that tiles are usually used in wet rooms, and this favorable conditions for fungal growth. Therefore, before puttying, the primer should be made with a special composition containing a fungicide.

Before laying, the wall is covered with a special waterproofing compound intended for subsequent laying of tiles. The composition is applied with a brush, preferably in 2 layers. The tiles are laid after the waterproofing has dried using tile adhesive, just like on other surfaces in damp rooms.

Hanging furniture and equipment

As already mentioned, plasterboard partitions using the KNAUF system, designed for hanging shelves, cabinets and other interior elements, are made with two-layer cladding. The technology for fastening hinged elements depends on weight, which determines the choice of fasteners.

For fastening the following are used:

butterfly dowel – up to 10 kg;
Driva dowel – up to 30 kg;
metal dowel for hollow structures Molly – up to 50 kg;
when hanging 45-75 kg in advance, two racks of reinforced profiles are used in the frame, as for the doorway. An embedded part is installed on them - a traverse, into which a self-tapping screw will then be screwed through the gypsum board without the use of a dowel.

For reliability, when selecting a fastening structure, it is necessary to take into account a safety margin of at least 30%.

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 ( 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 mentioned 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. The outer side of 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.

Knauf partitions, the technical characteristics of which are indicated in the table below, can also consist of arched profiles that serve as the basis 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 casing 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 pink in color. 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 the load-bearing elements and attach them with dowels (pitch - 200-400 mm).
There are vertical structures that are located at equal intervals (corresponding to half the width of the gypsum board).
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 a 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 utilities, you can begin attaching drywall. For these purposes, special screws are used. You should know that the sheets can be connected arbitrarily, but a checkerboard order is preferable. 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.
