Installation of plasterboard partitions Knauf. Knauf Technologies: drywall for walls, partitions, ceilings

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

Without going too far into historical digressions and amendments, just for the sake of interest, I would like to note that this company, which began as family business in Bavaria, presents 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 mark of 200. And now let's leave the historical and statistical calculations and move on to more practical things - technologies.

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. No wonder Knauf has practically no full-fledged competitors in the world market.

This success is based on two basic principles:

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

The company meticulously pays attention to every detail. Considering that they, as such, cannot exist - everything is important.

Let's start with the basics

The Knauf drywall installation instructions begin with highlighting the 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.

Gypsum boards of four main types:

Ordinary plasterboard sheets, intended for interior decoration premises that do not have special requirements: living rooms, offices, offices;
Gypsum board moisture resistant, which has a direct path to bathrooms, kitchens and other interior spaces where there is high humidity
Fireproof drywall, or special, is used to hide heating routes in rooms, as well as to hide electrical wiring, especially the lines of the leading general wiring;
Composite Fire Resistant Sheet. It needs no further explanation or introduction.

For your information! For the convenience of sellers and buyers, each sheet of drywall has its own color and its own marking. In domestic use, the most popular and often bought are ordinary gypsum boards and moisture-resistant gypsum boards, sheet thickness 12.5 mm on the walls, and 9 mm on the ceiling

metal profiles. Their purpose is the construction of a frame on the ceiling or wall for the purpose of installation drywall sheets in one plane. At the same time, it is allowed, and sometimes welcomed, 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, four types of profiles are also leading:

Ceiling CD profile is used to create a crate on the ceiling;
A guide ceiling UD profile, a profile with which a single (base) level is established for the entire ceiling structure, is placed along the perimeter of the walls as close to the ceiling as possible (unless it concerns raster variations, with a deliberate decrease in the ceiling level);
Rack CW profile, analogue of ceiling CD. It is from him that the jamb of the wall crate is formed, he also takes an active part in the creation of built-in niches, false walls, partitions;
Guide for CW profile UW profile. Analogue of UD with application in wall structures, the directions of application are the same as those of CW.

Connecting and extension elements, mounting options:

Suspension and straight, and universal, and hard-to-replace 120 mm. This is a really worthwhile invention, designed for fastening profiles to stationary walls and ceilings, installation is carried out with metal screws, the protruding parts are bent inward. By the way, the suspension is the leader in the number of folk names;
Ceiling profile extension CD-60. The main purpose is to cover the entire length of the room.

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

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

Single-level crab-type connector, crosspiece for connecting CD ceiling profiles. In this design, the overlay occurs on the main CD profile, and the side profiles are cut to the required length;

The connecting element is a two-level ceiling. The purpose of this design is to join the details of the crate when approaching the profile near a natural obstacle. T-connection;
Suspension for raster and hinged structures is designed for a significant lowering of the ceiling level. Gift of raster designs. One suspension can withstand up to 25 kg of ceiling weight.

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

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

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

Instruments. A lot of attention was paid to this point and it is not necessary to repeat, listing the entire set, but in order to refresh memories, we recall that there are tools:

Mandatory - their set is easy to calculate independently, based on the operations for which they will be used. Namely, cutting and cutting drywall sheets, cutting metal profiles, joining profiles and hanging plasterboard sheets and their fragments on the crate;
Additional - this is the so-called professional appendage, which will allow you to carry out drywall work without problems, provided that these works relate to your professional activity. In this case, you will need:
Strut lift, which allows you to do the work yourself without helpers;
Laser level for "shooting" the surface level;
A staple profile is not an essential tool, but it allows you to connect profiles to each other without self-tapping screws, it can also be used to connect any soft metal products, for example, when working with galvanizing;
Profile cutter - a master's tool, the purpose of which is to punch a hole in the structure for laying an electrical wire;

Peeling and edge planers, designed exclusively for working with drywall, one eliminates scraps of cardboard that are obtained when cutting material, the second prepares a joining edge for joining at 45 degree angles;
Needle roller - a tool for applying defects to a drywall sheet in order to give the surface a curved shape. It is applied at works by a "wet" method.

One of the most technologically advanced and economical solutions for construction or repair of an apartment is the installation of GKL sheets. With their help, you can easily fix all the defects of the walls, achieving a perfectly flat surface. GKL efficiency in manufacturing decorative elements, arches or boxes is proven by numerous design incarnations. Among total number manufacturers of drywall material favorably stands out the German company Knauf whose products meet all international standards. The components used in production do not contain any toxic elements and do not provide harmful influence for human health.

General information

Gypsum board is a three-layer structure consisting of two outer layers from cardboard and domestic from gypsum mixture. Depending on its composition drywall Knauf and its price are divided into:

usual(GKL);
moisture resistant(GKLV);
fire resistant(GKLO);
moisture resistant with increased resistance to open fire(GKLVO).

Sheet types can be easily identified by outward signs: moisture resistant varieties have green color cardboard, but ordinary – Gray.

The technological composition of the first type differs from others in the presence of antifungal and hydrophobic additives, as well as special cardboard.

By appointment GCL are divided into three types:

arched– thickness 6.5 mm;
ceiling– thickness 8 mm;
wall– from 10 mm thick.

In addition, sheets may have different types longitudinal edge, which Knauf drywall installation technology used for subsequent puttying of joints.

The dimensions of the rectangular material are 2,000 to 4,000 mm long and 600 or 1200 mm wide.

Preparing for the installation of GKL

The preparatory phase includes an assessment of the work surface for installation and choice necessary tool . The company's specialists advise to prepare:

utility knife, chisel or round cutter;
, trowel and grinder;
mixing nozzle and solution container;
building level, marking cord and tape measure;
screwdriver, square;
metal scissors;
putty Knauf Fugenfuller;
self-tapping screws, suspensions;
galvanized profile or timber.

Inspection of the surface is carried out in order to determine the material of the walls and their operating conditions. After that, a specific choice of GKL and consumables is made.

Highlights of Knauf drywall installation technology

Depending on the type of construction, as well as its purpose, plasterboard sheets can be attached both on glue and on metal or wooden frame . It must be said right away that wood is not the most the best choice especially in areas with high humidity.

The use of adhesive for fastening is permissible with wall irregularities that do not exceed 4 mm. In other cases, it is recommended to use a galvanized profile.

GKL installation option with glue

For an average room you need to prepare about 30 kg dry adhesive mixture Knauf Perlfix. She will provide secure fastening without extra structures, medium price of drywall mix Knauf – 285 rub. for a pack of 30 kg. Mounting technique sheets as follows:

pour the mixture into a container with water and mix;
cut sheets to size;
apply finished glue on the reverse side of the sheet with stamps with a pitch of 350 mm;
press the sheet against the wall and level it.

Important! The mixture begins to harden after 10 minutes. During this period of time, the plates should be leveled with a rubber hammer and a beam.

Installation of plasterboard on a metal frame

This drywall installation technology Knauf company allows for high-quality insulation and soundproofing of walls. After the measurements are taken, the process is the points:

cut the starting UD profile to size;
attach the UD profile to the ceiling and floor with dowels in increments of at least 1 m;
install direct hangers for fastening the CD-profile to the wall, not forgetting to put a soundproof tape; step not less than 1.5 m;
install the CD-profile with a pitch of 600 mm and fix it with screws with direct hangers and a starting profile;
install the sheet insulation and fix it on the frame with self-tapping screws with a pitch of 250 mm.

Important! To improve sound insulation performance, it is recommended to attach a special self-adhesive tape to the UD profile. The heads of the self-tapping screws must be recessed into the mass of the plate, it is advisable to use a special bit for a screwdriver with a limiter.

The average price of Knauf drywall sheets in the construction market

The cost of GKL, first of all, is influenced by its type and parameters. For example, the average prices for different kinds material:

ceiling 1200x2500x9.5 mm - 250 rubles / sheet;
wall 1200x2500x12.5 mm - 290 rubles / sheet;
arched 1200x2500x6 mm - 570 rubles / sheet;
GKLV 1200x2500x12.5 mm - 350 rubles / sheet;
GKLO 1200x2500x12.5 mm - 400 rubles / sheet.

When buying, you should think in advance and calculate the total amount of material, profile elements and fasteners. This will make it possible to organize a bulk purchase that will make price of Knauf drywall sheets a little lower.

conclusions

The technique of using gypsum boards in construction has a significant advantage - here there are no so-called "wet" processes, which are associated with the preparation and application of a significant amount of plaster.
The installation technology is quite within the power of any novice builder and has no special secrets; the purchase of a tool kit does not require significant financial investments.
Thus, for little money and with minimal labor costs, we get smooth and aesthetic walls, plus the possibility of embodying the most daring architectural delights.

What is the Knauf system, its advantages. The materials used in the kit, according to GOSTs. Tips for mounting various systems. Video examples of world manufacturer's systems.

Knauf wall cladding system

Drywall finishing material is widely used in repair work. They level walls and ceilings, create arches, partitions. To do the right thing, you need to follow the rules. To facilitate the work, global manufacturers produce complexes.

The Knauf system is the wall cladding most applicable by craftsmen.

Peculiarities

Working with KNAUF drywall sheets is practically the same as installing other plasterboards. However, the manufacturer produces necessary accessories to create a drywall surface. All materials assembled in a wall cladding kit are called a system. This simplifies the work, because all components are made for each other. No need to think about installing non-standard additional elements.

The benefits of using technology

The KNAUF complex includes all the necessary elements for facing a wall or creating a partition. This has advantages:

use of materials High Quality that guarantee long term operation;
ease of calculation necessary materials for installation;
the KNAUF kit includes detailed assembly instructions;
if you purchase GKL and accessories separately, any small details are often forgotten. Everything is included in the kit.

Each design has its own purpose: ordinary partitions, double cladding, and so on.

GKL types used in KNAUF systems

The GKL kit for wall cladding has the following types of sheets:

Drywall gray color– thickness from 9.5 mm. used in rooms with moderate humidity.
Green moisture resistant sheet - systems with such sheets are used in wet rooms.
Green with a red inscription, combined - a combination of moisture-resistant and refractory materials.

Wall cladding with systems is carried out according to 2 methods: frame (metal lathing from profiles) and frameless (gluing sheets to the adhesive composition).

Knauf installation technology: drywall, walls and partitions

The Knauf installation technology is not much different from the generally accepted work on wall cladding and partitioning.

When assembling the structure, you must adhere to some rules:

drywall sheets are fixed on a metal, wooden frame from the center or from the corner. This is done so that the fox does not deform. Screws NK 11 are used for fixing.
To create a strong joint between the sheets, they are mounted close to each other, without leaving a gap.
GCR is mounted so that there are no cruciform seams. Sheets on the surface must be displaced.
To use the frameless method, sheets of 12.5 mm must be selected.
For gluing sheets use PERLFIX glue. After gluing, the master has 10 minutes to level the sheet on the surface.
When laying warm insulating material for fastening the plasterboard to the frame base, the kit includes 35 mm screws for a wooden base and 25 mm for metal profiles.
Knauf profile is cut with scissors for metal.
A soundproof tape is applied to the guide profiles before fixing.
For good sound insulation, it is necessary to retreat at least 50 mm from the draft wall to the guide.
If a partition of the Knauf system is created, with a room height of 2.80 m door leaf must be 90 cm wide and weigh up to 25 kg.

Knowing these rules, the assembled assembly will be a strong, rigid structure.

On what surfaces is cladding acceptable?

The Knauf design is applicable in various areas: walls, ceilings, floors.

Frameless method applicable for concrete, brick walls. When installing the system in this way, it is necessary to choose the right primer.

The frame method is used if the room is damp, the walls tend to get damp, there is a desire to improve sound insulation and thermal insulation with the help of additional material.

there are kits for creating suspended ceilings;
kits for working in the attic - fastening from the side of the rafters.

GKL KNAUF kits are mounted on various surfaces. Each of which has its own requirements and the implementation of certain rules.

How much does cladding cost

Knauf releases a large number of complexes applied to various surfaces with various equipment. The pricing policy depends not only on the complexity of the system itself (the false ceiling has a large number of components), but also on the materials (gypsum board 9.5mm or 12.5mm).

Refractory GKL has the highest cost among all sheets, and double sheathing with sheets is much more expensive than installation in one layer.

How effective is Knauf drywall / walls / partition technology: heat consumption rates

Knauf kits use heat, - soundproofing materials according to GOST 9573-96, 21880-94, 10499-95, as well as materials included in the "List polymer materials and structures approved for use in construction by the Ministry of Health of the USSR "- M. 1985. Having a conclusion on compliance sanitary standards Legislation of the Russian Federation.

To maintain the norms of heat consumption in the room, Knauf systems have materials, the calculation of which is carried out individually for each case (dry, but cold rooms, wet rooms).

The heat-insulating layer is laid only in the frame base. It is impossible to apply insulation in the frameless method.

Plasterboard wall cladding: is it possible for yourself

For the installation of the GKL system, detailed instructions are included in each kit, so it is not necessary to call the wizard. However, we must not forget that the GKL sheet has its own weight even under certain installation work it will not be easy to lift it alone with glue or to the ceiling.

Experts know the intricacies of working with various systems, this gives a guarantee not to make mistakes and get a solid durable construction.

Examples: video tutorials

The use of the frameless method is shown in the video:

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 is certain rules installation of these structures, which 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 full list all necessary elements indicating their number.
Each set is supplied by the manufacturer detailed instructions for assembly, thanks to which 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

Required preparatory work: alignment and marking. After that, a partition is placed:

Guide profiles are attached to the dowels.
Through the selected optimal intervals are set vertical racks. 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.
Spend finishing 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 elements the frame is 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. Later they are filled special composition, produced by the same company "Knauf".
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 bars for the crate.
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 apply drywall different types: moisture resistant, fireproof and common 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 to attach to the wall household appliances, which has a solid weight, you will have to make a double frame with reinforcement.

Features of the formation of corners from drywall

important role in the device drywall construction corners play. If they are assembled incorrectly, then through 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 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.
