New building technologies. Partitions made of plasterboard sheets (GKL)
Alfons and Karl Knauf are brothers. Both were educated as a mining engineer and, due to the nature of their activities, were particularly interested in natural material- plaster. 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. As if time itself helped 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 factory in the city of Perl. They began to produce dry construction mortars 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 is currently located here. In 1958 they opened the first gypsum board factory.
During the German economic heyday, the company rapidly developed from a relatively small company into a family with subsidiaries around the world. In 1993 they begin their activities in Russia. Many enterprises equipped with modern equipment are opening across the country, where a single production technology and quality standard are used.
Knauf products
But Knauf does not rest on its laurels, the company is developing new projects, offering the consumer:
- range 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 on other innovative compositions;
- are held special courses 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 sheets;
- tongue-and-groove gypsum boards;
- dry gypsum and cement mixtures;
- primers, other compositions for interior decoration, ready for quick use;
- building chemistry;
- metal profiles;
- drywall sheets.
We will dwell on the last two groups of goods and tell you what drywall and Knauf profile are, about production characteristics, dimensions and installation.
Varieties of drywall Knauf
Products manufactured by this manufacturer are used to perform work on interior decoration"dry" way. It's practical and fast. Drywall sheet is classified by properties:
- ordinary, some builders also call it standard,
- moisture resistant
- refractory.
Plain drywall
A sheet of ordinary (standard) drywall is used in rooms where the natural temperature regime is preserved and normal humidity. They can be coated internal walls residential premises, offices, enterprises.
Standard sheets for outward sign differ from other species in color solution- have grey colour And blue marking. 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 to people and environment;
- helps to radically change the space and interior of the room. With the help of such a sheet, a partition, an arch, a fireplace are quickly erected;
- it is perfectly lined with any finishing materials: plaster, tiles, wallpaper, paint, stone;
- 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 drywall sheets for walls:
Moisture resistant GKL
Sheets of moisture-resistant drywall should be used where it is intended high humidity or the room is poorly ventilated. Specifications sheets make it possible to install additional partitions, ennoble the walls:
- in the shower, bathroom;
- in swimming pools and saunas;
- in the toilet rooms;
- in sanitary facilities.
For these works, it is better to use the Knauf sheets shown in the table below:
The color of the leaf is green and has blue markings.
Fire-resistant drywall sheets are used where the temperature is elevated and the measures for fire safety. The technical characteristics of the named finishing material indicate that they can:
- facing the walls of wooden buildings;
- to carry out installation in home boiler rooms, furnaces, sanitary facilities of enterprises;
- ennoble fireplaces;
- sheathing the walls of evacuation exits.
For these purposes, Knauf offers the following sheets:
It differs from other types of GKLO pink and red markings.
Now that you know what types of drywall are, its dimensions, specifications, insignia, you can proceed to the next section and find out how the sheets are mounted to a vertical surface.
Metal frame elements
All metal profiles at Knauf enterprises are manufactured according to the conditions TU 1121-012-04001508-2011. These are elements of a certain length, made from a steel strip using the method cold rolling on profilegibochny modern machines. They are galvanized for protection against aggressive environmental influences.
With the help of such structures, a frame for sheathing is assembled, it is they who serve as a rigid base, on which drywall sheets are then laid.
Profiles have standard lengths: 2750, 3000, 4000, 4500 mm. But at the request and in 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, hacksaws or other devices.
The following structures are required for the frame:
- rack profile. In appearance it looks like the letter "C" and acts as vertical racks of the future frame. Mounted in tandem with the guide profile. You can learn about its geometric dimensions from the article "";
- guide profile. This piece is U-shaped. In the frame, it has the function of a guide for the rack profile and serves to install 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 jumper over the opening;
- ceiling profile. It is presented in the form of a C-shaped long part, it performs the function of a vertical rack of the frame. For its fastening to the wall, a direct suspension is used, which can be fixed with screws;
- screws and dowels are used as fasteners, which are described in detail in the article "";
Installation of drywall on walls using Knauf technology
Knauf brand gypsum boards are quite popular on construction market Russian material. The technology of their installation enjoys a significant advantage over other facing building materials.
The absence of so-called wet processes during operation significantly reduces the time, installation becomes easier. With minimal labor and financial costs, a perfectly flat surface is achieved.
Designers had a unique opportunity to realize their most daring projects. And the technology of laying sheets is so simple that a person far from construction can do it.
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 GKL can be installed in two ways, each of them has its own technical differences:
- frameless method. In this version, the sheet is simply glued to the base. But you should know that the area to be cultivated must be very even and always clean;
- using a framework. It can be presented in the form of a structure made of lumber and metal. Wooden will cost a little cheaper, but it is not so convenient to use and not durable. And here is a metal set of profiles Knauf widely known and popular among professionals and amateurs. All parts are produced at the drywall 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.
According to Knauf technology, the entire process should include the following steps:
- Frame preparation;
- Its installation;
- Sheathing the frame with sheets;
Installation work should begin before the installation of a clean floor, provided that plumbing, technical and electrical systems. Temperature regime not less than +10 °С and the humidity must be normal, this mandatory requirements according to SNiP 23-02-2003. If it is winter time, the building must be heated.
This technology makes it possible to insulate a room without problems, improve sound insulation in it, lay and hide communications, and create various structural elements.
Necessary tools for installation
Each specialist has a certain minimum of tools and devices. We recommend you a standard set, without which you can not do:
- construction level, plumb line, hydraulic level;
- screwdriver, perforator;
- metal scissors, electric scissors, grinder;
- mounting knife;
- simple pencil;
- roulette;
- a thread;
- sealing tape.
Installation of a metal frame on the walls
This profile is more durable and reliable. All varieties are produced in industrial enterprises Knauf and meet the standards. The installation process undergoes quality control at all stages of work: first after the installation of the frame, then after laying drywall, then - joints and seams.
- Let's mark up on the floor surface, and then transfer it to the ceiling and walls. In order to accurately install, experts recommend marking the attachment points of the rack profiles, the type and thickness of the plasterboard.
- 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. According to the marking signs, install and then screw the guide profiles 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, fix the direct hangers to the wall using the appropriate dowels. Step no more than 1500 mm. To weaken the "sound bridges" lay a sealing tape between them.
- We install the profiles in the guides and fix them with screws. Interfering ends of suspensions should be bent or cut off.
Laying drywall on a metal frame
This technology is:
- We start working from the corner with a pitch for screws 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 skin 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 GKL, the latter being less than the first, then segments of the guide profile are added to the horizontal joints and then the GKL is sheathed.
Docking of sheets is carried out in a run. Avoid joints at window studs or where there is a drywall doorway. 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.
Moments that should not be forgotten when installing plasterboard on walls
Do not forget to leave a gap of 10–15 mm between the plasterboard and the floor, and 5 mm at the junction with the ceiling. Subsequently, it will be closed with a putty solution and will be glued with a separating tape, the edges of which will then be carefully cut off.
External docking corners can be reinforced with a protective perforated corner. When finishing, it will be completely puttied.
Where the sheet is paired with door or window frames, decorate its edges with decorative trim when you finish.
For moisture-resistant drywall sheets, screws with a sharper cone head are used. The step is not more than 300 mm.
If there is a need to hang a hundred or on the wall, then be aware that with a weight of no more than 10-15 kg per 1 running meter wall surface, it can be fixed with special anchor bolts for gypsum boards or dowels for gypsum boards anywhere. It may not be heavy openwork shelves, cornices, paintings, sconces or others. lighting. But if you plan to use 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 of a metal frame.
Once your walls got new outfit, you should start puttying, processing joints and places where the caps of the screws are located.
But we will talk about this in an article that will be called ";".
Partitions made of plasterboard sheets (GKL)

In the manufacture of a single interior detail or the implementation of the entire repair and construction project, one should adhere to the exact technology. Each manufacturer of relevant materials, mixtures and parts give a number of recommendations on the use of their products, following which you can achieve the expected effect during operation and fit into the guaranteed period of use of the final product. Partitions Knauf systems can be considered one of the most striking examples on the market construction products where the above axiom actually works.
Why Knauf? This brand is known to many, but during repairs, not everyone decides to purchase materials from this brand, as they are afraid to go beyond the budget. Having considered the device of partitions from sheets Knauf, you will understand whether this method is yours, what is remarkable about it, and how much it will cost to repair this system.
To understand the essence and differences of these partition structures from other options, it is worth getting acquainted with their types.
There are four types of such structures:
- Partition wall model W111;
- Partition wall model W112;
- Partition wall W113 (fireproof);
- Security wall W118.
Each of these types has its own characteristics.
The device of partitions according to the Knauf system - W 111
This design consists of a frame, which is covered on both sides with sheets of drywall. Inside the structure, a layer of sound insulation is necessarily placed.
Guide profiles are fixed to the ceiling, walls and floor, using dowels. After sheathing the GKL, the joints are sealed special composition Uniflot. The places where the walls come into contact with the ceilings are subjected to sealing.
It happens that the structure reaches a length of 15 m, in which case movable seams will have to be made in it. Thanks to them, the partition will have the possibility of linear expansion. To do this, two racks are placed at the seam.
An insulating material is always placed between the profiles, and a metal profile with an elastic insert inside is placed between the drywall sheets.
You can also consider special cases of such partitions from GKL:
- For example, the rack profile has a size of at least 75 mm, then the installation of a movable seam has such a feature - it is placed between two additional racks. They will be smaller in size than the main racks, the difference will be about 25 mm. Then the drywall sheets will have a thickness of 12.5 mm, this will compensate for the difference.
- If there is also a suspended ceiling in this room, then in order to mitigate the possibility of subsidence of the floor structure, the partition is attached with a movable joint.
Partition wall W112
It also consists of a metal frame and drywall sheets, with which the frame is sheathed on both sides. Between these sheets there is a soundproof layer. The height can also be different, depending on the objectives of the design.
Installation steps are the same as above. The subtleties, in which the differences lie, is that the structure is sheathed on both sides with additional GKL. This is done in order to improve the soundproofing qualities and increase the fireproof properties of the device.
Partition wall W113
The partition includes all the same metal carcass, which has a three-layer GKL lining. Inside the device is a non-combustible layer of sound insulation. It fits between sheets of drywall.
Since the structure is distinguished by a three-layer sheathing, the distance between fixing the guide profiles will be no more than 500 mm.
Air duct surfaces pass through such partitions; they must have reliable fire protection. Often this is a casing with a fire resistance above 0.5 hours.
Security Wall W118
This type of device resembles the design features of the W113. But W118 differs in that a galvanized sheet half a millimeter thick is placed between the drywall sheets. The installation of this structure requires strict compliance with the requirements that are prescribed for fire walls.
This type of partitions has a reinforced frame, which is made of metal profile PS 100. The thickness of this profile is not less than 0.6 mm.
Factors influencing the choice of the type of complete partitions
The manufacturer of German construction products offers its customers a wide range of installation kits drywall partitions. To date, there are more than twenty types of partitions. They are marked with the letter "C" with the prefix of the corresponding number (for example, C 111, C 115.2, etc.).
The specific type that should be applied indoors will depend on several factors:
- total height of the room;
- permissible noise level;
- estimated additional load on the wall;
- condition and type of material base surface fastenings;
- the need for laying / hiding in the box of communication systems;
- availability and type of door (pendulum, hinged, sliding);
- the required height of the partition;
- humidity and temperature levels;
- type of premises and its functional purpose.
Advantages
On the territory of the countries of the post-Soviet space, a couple of decades ago, the word "European-style renovation" was firmly associated then with the exotic material "drywall". This and other related products of its production were first launched on the market by building materials new generation German company Knauf. At the same time, the leading specialists of the enterprise developed detailed instructions for the construction of suspended, frame and frameless structures lined with plasterboard sheets. The high quality of products, combined with a well-chosen set of marketing techniques, allowed the company to become a leader among competitors in the shortest possible time.
Today, Knauf produces a number of kits for the manufacture of partitions, which, depending on the purpose, have different configurations. A step-by-step and detailed explanation of the installation process allows you to install the partitions of the Knauf system with your own hands, without wasting time studying the building materials market and independently searching for the required components of the structure.
Also, the convenience of such kits lies in the simplicity of calculating the cost of one square meter finished product. In addition, it is also not difficult to determine the consumption of materials.
One of the important advantages of the set should be considered the exclusion of the "forgetfulness" factor. All necessary basic and additional parts are included in the kit.
The purchase of complete Knauf partitions will eliminate various misses and inconsistencies that are very common when using materials from various manufacturers for mounting the structure.
Constituent elements
Knauf has a fairly wide range of complete systems, each of which has a specific purpose and place of application.
Drywall sheets
Depending on the conditions of use, as well as the properties of this sheathing material, there are:
- ordinary sheets (GKL);
- refractory (GKLV);
- moisture resistant (GKLV);
- combined (GKLVO).
In addition, outwardly the sheets differ from each other in the type of edge, depending onmethod of processing technological joints:
- PC - straight edge;
- ZK - rounded edge;
- UK - edge, thinned on the front side;
- PLUK - an edge with a refined and semicircular edge on the front side.
- PLC - the edge is round on the front side.
Depending on the area of application and the required dimensions of the final product, drywall of various dimensions is used for the installation of partitions:
- Length: from 2000.0 mm to 4000.0 mm.
- Width: 600.0 mm and 1200 mm.
- Thickness: 6.5mm to 24.0mm.
metal profiles
They are metal products made of a sheet of rolled steel with a galvanized coating. Used to build a frame for plasterboard partitions. The standard length of these elements varies from 2750.0 mm to 4500.0 mm.
From above, the parts have grooves that give the finished structure additional rigidity.
For mounting the base for drywall, two types of profile are used: guide (NP) and rack (SP). They must have comparable cross-sectional dimensions.
Guide feature Knauf profiles it should be considered that they have holes for fastening, which makes it possible to reduce the coefficient of deformation of the part and, to a large extent, reduce the time for installing the frame.
The functional task of the data metal elements is to hold the rack profiles in a given direction, as well as to stiffen the plasterboard partition as a whole. In addition, it is used to make jumpers inside the structure.
Rack profile
The section of the part has a C-shape. The joint venture is installed vertically.
It is fixed due to the guide profile by one of three methods:
- butt;
- nozzle method;
- the “cut-off with a bend” method (used most often).
The side walls of the rack profile have holes designed for easy installation of electrical wires.
Wooden slats
Designed for manufacturing wooden frame drywall partition. These elements are usually square section. Just like a metal frame, a wooden one has guides and rack-mount parts. The vertical ones should be installed at the same distance from each other (as a rule, the mounting step of the racks is 30.0 or 40.0 cm).
The moisture content of the material used for the wooden base should be in the range of 10-12%.
Additional components
In addition to the listed main elements of the Knauf system partitions, various fasteners are also used, the type of which will depend on the difference general level the base plane, as well as the material from which the mounting surface is made and the degree of wear.
To improve the soundproofing properties of the partition, the voids of the frame must be filled with an appropriate material. The German manufacturer advises the use of mineral and fiberglass fillers that meet sanitary and epidemiological standards, with high rate noise reduction index.
Mounting technology
Installation of this design is, of course, similar to standard installation. But still, the technology has its own characteristics, which I want to focus on.
Features of the installation of partition structures according to the Knauf system:
- The designers of the Knauf company have developed some recommendations that must be followed at all stages of installation;
- Knauf partitions are equipped with guides (upper and lower), as well as racks, their width depends on the weight of the structure and on the height of the room;
- The guide profiles must be fixed to the ceiling with dowels, the step will be equal to the step of the risers, you need to fix it in at least 3 places;
- Rack profiles will be fixed with a distance of 600 mm from each other, sometimes it can be less;
- Racks need to be fixed using the “cut-out with a bend” method; Knauf self-tapping screws can also be used;
- If the structures are to be fixed to a false ceiling, the fire resistance class is always observed;
- As for sound insulation (and the partition should be like walls, soundproofed), mineral wool is most often used as an insulator layer;
- The peculiarity of the installation of sheets is that they need to be installed without a gap, end-to-end;
- The laying of sheets should take place in such a way that there are no cross-shaped seams.
The installation of the frame also has its own characteristics - the joints of the plasterboard partition above the doorway should not be on the racks to which the box is attached. The seam must be placed on an intermediate guide that is installed above the horizontal beam. It, in turn, is the upper bound. These measures are necessary to ensure that the service life of the structure is long.
Obviously, without using plasters and other “wet” repair elements, the cost construction works decreases. Therefore, the difference between these materials, and materials of the lower price segment, is offset by savings on the same plaster.
Partition walls - devices made of plasterboard sheets that change the appearance of the room. These walls, built on their own, allow you to zone the apartment, divide the rooms into functional parts, and at the same time be separate. decorative element. Knauf specialists are constantly looking for new technologies and studying the demand market for construction products. Thanks to the application modern methods production and the desire to expand the sales market, complete partitions of the Knauf system for for long years remain a leader in their field, offering consumers more advanced new products every year.
Prefabricated partition systems made of plasterboard Knauf (video)
To date, drywall is the most popular material for finishing partitions, decorative installations, niches and arches in rooms. But it is worth noting that these structures need a strong support. Wooden or profile frames are used.
PPR Knauf is in the greatest demand today. The frame of such a base is exclusively metal, and the installation itself is made of drywall sheets. But the manufacture and installation requires compliance with certain rules in order for the design to be integral and reliable.
Material for thermal and sound insulation
Knauf technology - the installation of drywall partitions - involves the use of practical and high-quality materials: profiles, drywall sheets, screws, cutters and fillers.
Installation of PPR partitions gives high results, because at the junction of the rack and rails, bumps and protrusions do not form. This results in additional savings since there is no extra costs for finishing mixes.
Installing Knauf drywall sheets is a mandatory use of moisture-resistant materials. It is important that the manufacturer indicate the moisture-resistant PPR indicators on the packaging. in the assortment of this kind of products there are five standard sizes, which speeds up the construction of drywall installations. If it is planned to increase heat and sound insulation in the room, then builders recommend using mineral wool.
It should be noted that Knauf fasteners and hardware are made of durable look plastics, and metal parts treated against corrosion.
Characteristics of Knauf products
The standard set of metal profiles includes prefabricated parts for frames (rails, bearing and rack parts). The length of the profiles is 3-4 meters. If the length of the frame is insufficient, then it can be increased without problems, you just have to take into account the unified dimensions of the sides of the profile. The extension is carried out in an overlapping manner. But the masters say that its length should not exceed the height of the side profile side.
Partition wall mounting technology If this connection is equipped additional elements, then the overlap is also twice as long. For the installation of such profiles, self-tapping screws are used, holes for which are made along four edges and two in the middle. Be sure to stick the sealing tape on outside profile. This foam rubber tape isolates the joints.
The distance between fasteners depends on the design of the frame, but cannot be more than one meter. Professionals recommend taking a step no more than 0.3 meters. The structure is fixed with dowels and self-tapping screws.
Installation of Knauf partitions: advantages
This company's products are durable and high quality, therefore, the installation of such partitions should be carried out at the proper level. . There are several rules that are recommended to be followed in order to achieve excellent construction results:
- The outer part of the profile is completely glued with thermal insulation tape before fixing the PPR sheets. If the profiles freeze, then the moisture from the condensate will not reach the walls.
- If you do not plan to hang anything heavy on the wall, a sufficient profile step is 60 centimeters. Otherwise, this distance is reduced.
PPR partition reinforced according to the described technology - The construction of Knauf plasterboard partitions is provided only on solid walls. To achieve this result, they work exclusively with a double profile (one profile is inserted into another, covering about ten percent of the width of the product).
- Docking of long drywall sheets is carried out in a checkerboard pattern to achieve the maximum aesthetic appearance walls to finished construction did not vibrate and did not deform over time.
- For good connection parts between each other according to the rules of this technology, it is necessary to work with a cutter or with Knauf screws.
The device of drywall partitions, their types, insulation and soundproofing
There are several types of partitions, depending on how many skins are present on the product:
- Partitions with lining in one layer;
- In two or three layers;
- sheathing combined type: two-layer on both sides of the product;
- Three-layer sheathing: moisture resistant sheets with steel intermediate sheets.
Partition single type double layer If structures are installed simple type, then additional materials are not needed. But if there is a desire, the gap between the wall and the frame can be filled with a special material with soundproofing or insulating properties.
Master class from the manufacturer:
Masters claims that the pricing policy of such materials is not at all an indicator of their quality. To get wonderful soundproof material, it is enough to use egg cartons in the work, and mineral wool will help to keep the heat in the room best of all. Also, the base of the foil acts as a heater, which, on the one hand, perfectly retains heat, and on the other, repels it.
- this turnkey solution from drywall and insulation, going along with fasteners. They are easy to install and are famous for their high quality and fire-fighting properties.

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 instruction 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. In the future, they are filled with a special compound produced by the same Knauf company.
- When building partitions from gypsum boards with window niches or doorways, it is forbidden to join sheets above them. Otherwise, there is a risk of seams coming apart due to vibrations that occur when using windows and doors. Docking of elements is carried out closer to the corners of the room.
Types of structures provided by Knauf
The sets differ from each other in the number of skins, thickness and frame design. All partitions use branded insulation based on mineral wool. There are the following kits:
- C 111 - with one layer of sheathing. The minimum thickness and instability to loads do not allow such a design to replace a full-fledged wall, its function is decorative and zoning.
- C 112 - sheathing in two layers on each side on a single frame.
- Sets C 121 and C 122 are similar to the two described above. The difference is that instead of profiles, they use wooden 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 of plasterboard sheathing are screwed end-to-end, so that the plane of one element overlaps the end of the other, and are reinforced with a special corner profile. You can fix it with putty or PVA glue.
Curvilinear ribs are reinforced with a flexible plastic corner.
