Drywall is used to create arches, various decor rooms, partitions, wall openings, etc. Creating beautiful decorative elements cannot do without a strong support, which is represented by Knauf partitions. What is a Knauf partition? In fact she looks like plasterboard construction, in which the frame consists entirely of a metal profile. The design is created using a special technology that eliminates various unforeseen circumstances.
Knauf partitions can be different. They are installed in different rooms, with different sound insulation, for different purposes. Partitions can be different types and are divided according to certain parameters.
According to their design, partitions are divided into:
In addition to these types, there are partitions with built-in special channels for ventilation and communication. Next parameter, according to which the partitions are divided - this is the frame, or rather its type. Frames can be double or single.
The use of partitions based on a double frame is recommended if you need to create a strong a reliable wall, which will withstand heavy .
Creating partitions with single frames is recommended in places where sound insulation is not so important and the walls will not be burdened with heavy pieces of furniture or appliances. We can conclude that the double frame is more durable.
Why is drywall and Knauf partitions so popular? Since the 90s, drywall has been almost synonymous with the word European-quality renovation. On Russian market this material appeared thanks to the Knauf company. The material was accompanied by instructions that described in detail how to create various designs from plasterboard sheets. The technology has gained great popularity due to the excellent quality of the product.
The main advantages of Knauf plasterboard partitions are as follows:
The use of Knauf partitions is still popular today. The correct selection of a set of partitions can provide excellent sound insulation, high strength and reliability of the walls. As mentioned above, there are different strengths and sound insulation, depending on the type of room you should choose a suitable kit.
The installation technology using the Knauf system is not much different from the standard installation procedure. However, there are still some differences, which will be discussed below. Together with the drywall material, the Knauf company brought special technology And general recommendations for the installation of partitions.
They look like this:
In addition to the above recommendations, it is necessary to take into account the installation features of the frame. In order for the entire system to serve for a long time, you need to ensure that the joints from the gypsum plasterboard partition above the door opening are not located on the racks attached to the frame. Instructions for assembling the frame for fastening gypsum boards in our material:.
In addition, the seam must be made so that it is in that part of the intermediate guide that is located above the horizontal beam. Horizontal beam serves as the upper limit. Following these recommendations will help you make a long-lasting, high-quality design.
Exist Various types partitions that suit different room parameters. At the moment, there are about 25 kits for installing partitions using the Knauf system on sale. All sets are marked with the letter "C", which is combined with a specific set number.
To select the right installation kit, consider the following factors:
Having decided on the parameters of the room, it will be much easier for you to choose a partition. For example, a bedroom adjacent to the kitchen or living room requires a high degree of sound insulation, so the installation kit should be selected accordingly. If the bedroom is adjacent to the wall of the neighboring apartment, then even more so the partition should have a high degree of protection from unwanted noise.
Plasterboard partitions Knauf - worthy and reliable way to build a wall in the desired location. Simplicity and ease of use and installation will help make the installation process easy and enjoyable. With this technology, the issue of unnecessary noise will be closed for you forever.
Many craftsmen who install suspended ceilings have mastered the technique in practice, adopting the necessary experience and knowledge from more experienced installers. But when the work requires drawing up a work project, and at the end it is necessary to provide reasonable guarantees of the technical compliance of the design with SNiP standards, many experience difficulties. Craftsmen from any reputable organization design and install plasterboard on the ceiling in accordance with the recommendations contained in the standard routing Knauf.
If for an amateur GOST and SNiP are a “dark forest”, then for a professional the technological map is a universal guide on how to technically and quickly assemble a frame and screw drywall.
Important! If the work is performed under a contract, then when placing and submitting an order you cannot do without the recommendations of the Knauf technical map for drawing up project documentation.
The latest current Knauf technological map (series 1.045.9-2.08.1) is comprehensive on how to design and install a suspended ceiling structure under plasterboard and gypsum fiber boards. All work is divided into separate sequential stages, so understanding the technology will not be difficult.
The frame for the ceiling is made of metal Knauf profile, and from wooden blocks.
There are 5 types of suspended ceiling designs:
For wooden structure P 111 uses coniferous bars with a moisture content of no more than 12%. Before installation on the ceiling, they are treated with an antiseptic and fire retardant. The recommended cross-section of the bars is 50×30 mm.
The metal frame for the ceiling is made of long rolled elements made of thin sheet steel.
Frame with fastening to the base (P 112, 113). To assemble it, take a regular ceiling profile. It consists of the following elements:
The ceiling of the P131 system with fastening to the wall is made of a more powerful profile for the installation of partition structures (PS).
To strengthen the structure at the junction of rooms, use reinforced profile UA on the ceiling.
Profile connection work is performed using the following elements:
Frame installation work ceiling Knauf performed using the following elements:
Important! Not everyone knows that U-shaped hangers are produced under the profile and under the beam. Although they are similar in appearance, they have different nominal sizes after folding the side strips. For wood it is 50 mm, and for a profile – 60 mm.
Depending on operating conditions, required drywall Knauf is chosen from the following varieties:
Type A. Regular construction drywall. This sheet is used for heated rooms with normal level humidity (up to 60%).
Type H2. Drywall with increased moisture resistance. The leaf has a low level of water absorption (up to 10%). Room humidity can be up to 75%.
Type DF. Flame resistant drywall.
Type DFH2. Drywall with the properties of the two previous types.
Important! Initially, it is customary to calculate the frame specifically for ceiling plasterboard size 1.2x2.5 m and thickness 9.5 mm. But drywall comes in other sizes.
The drywall has a factory-made longitudinal edge. The most technologically advanced and therefore widespread is the semicircular thinned one, but there is plasterboard with other types of edges:
Each type of edge is needed to solve specific structural problems. In particular, installation of figured corner protrusions.
The work is carried out in a dry and heated room at an air temperature of at least +10 degrees.
Work on the implementation of any frame begins with marking the design position of the ceiling surface. Using a level and a tapping thread, mark the corresponding line on the walls around the perimeter.
Further, depending on which Knauf drywall is selected for suspended ceiling, work is being done to mark the location of the guides and mounting points for the suspensions. The lines of the supporting guides are marked in accordance with the length of the sheet so that the end joint falls on the profile.
At the marked points, hangers are attached to the ceiling with dowels or anchors.
The wooden frame is mounted in two ways:
Installation of a profile frame:
Important! The edge of the sheet, not covered with cardboard, is processed with a plane to remove the chamfer.
The manufacturer has prepared a video in which craftsmen demonstrate the principle of assembling a suspended structure
The work of screwing Knauf sheets is performed in pairs or using a lifting mechanism. Plasterboard is mounted on the ceiling without T-shaped joints, staggered. In this case, the sheet is shifted by the step of the supporting profile. Installation is carried out so that the sheet lies in the longitudinal direction without a gap, and in the transverse direction there is a small gap. This way the putty will completely fill the joint, and the seam will be strong.
When temperature changes, the plasterboard sheet expands, so large rooms it is necessary to provide expansion joints with a pitch of 15 m.
To make it easier to putty the self-tapping screws, screw them in with the head slightly recessed into the sheet – 1 mm. The work of sealing joints is carried out using reinforcing tape.
Drywall – universal material, and the Knauf technological map will help you complete high-quality installation any design, even for a novice master.
Partitions with cladding made of sheet materials Knauf are designed for installation in residential, public and industrial buildings.
The use of partitions KNAUF technologies in most cases it turns out to be more advantageous in comparison with known designs from piece materials(bricks, blocks, etc.), since the installation speed of KNAUF partitions is higher, the weight is less, and wet processes in the work are excluded.
An additional advantage of dry construction systems is the ability to quickly dismantle.
Knauf has developed a range of specialized partitions to meet the increased requirements in the field of fire safety, sound insulation, shock resistance and even X-ray protection.
The use of special systems and well-chosen types of KNAUF sheets makes it possible to achieve high fire resistance limits and airborne noise insulation levels for various rooms.
To get started, you need to remove debris, dirt and dust from the work surface.
Mark the position of the partition on the floor, walls, ceiling. Mark the locations of the openings (if required).
Glue KNAUF-Dichtungsband polyurethane sealing tape to the back of the rack and guide profiles adjacent to the walls, floor and ceiling.
The tape is needed for a tight fit to the base and additional sound insulation.
Mount the frame from metal profiles.
Install KNAUF rack profiles (PS) into KNAUF profiles with guides (PN) vertically at a given pitch.
Secure the rack profiles with a cutter.
Cover the frame with KNAUF sheets on one side.
Sheathe the frame with KNAUF sheets on the other side.
Apply KNAUF-Tiefengrund primer to the joints of the first layer of plasterboard.
Putty the joints of the first layer without reinforcing tape.
Sheathe the partition with a second layer of KNAUF sheets on both sides so that the joints of the second layer do not coincide with the joints of the first layer.
If necessary, make holes for sockets and switches.
Putty the joints of the second layer using reinforcing tape.
Alfons and Karl Knauf are brothers. Both were educated as mining engineers and, due to the nature of their activities, became 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. 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. There 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 equipped with modern equipment, where a uniform production technology and quality standard are used.
But Knauf does not rest on its laurels, the company is developing new projects and offering the consumer:
Knauf enterprises produce high-quality finishing materials:
On two latest groups products, we will stop and tell you what drywall and Knauf profiles are, about production characteristics, sizes and installation.
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:
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:
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:
Sheets moisture-resistant plasterboard should be used where it is intended high humidity or the room is poorly ventilated. Specifications sheets make it possible to install additional partitions and improve the walls:
For these works, it is better to use Knauf sheets shown in the table below:
The color of the leaf is green and has blue markings.
Sheets of fire-resistant plasterboard are used where the temperature is high and fire safety measures must be strictly observed. Technical characteristics of the named finishing material they say that they can:
For these purposes, Knauf offers the following sheets:
GKLO differs from other types pink and red markings.
Now that you know what types of drywall there are, its sizes, technical characteristics, insignia, you can proceed to the next section and find out how to install sheets to a vertical surface.
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 for protection from aggressive influence environmental protection are covered with galvanized coating.
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:
Knauf brand plasterboard sheets are quite popular in construction market Russia material. 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.
You need to know that gypsum board can be installed in two ways, each of them has its own technical differences:
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:
Installation work should begin before the installation of a clean floor, provided that the room has plumbing, technical and electrical systems. The temperature should be at least +10 °C and the humidity should be normal, this 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.
Each specialist has a certain minimum of tools and equipment. We recommend a standard set that you cannot do without:
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.
This technology is:
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.
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 frames, 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 it on the wall, then know that with a weight of no more than 10-15 kg per 1 linear meter of 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 of the 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 “;”.
The concept of “dry” construction implies the design and construction of lightweight frame-sheathing structures, the installation of which requires a minimum of money and physical effort. German KNAUF company produces high-quality materials necessary for such work and is a kind of legislator, defining standards for this type of activity. The KNAUF system for plasterboard partitions is known to any professional builder. Now it’s our turn to get to know these structures in more detail.
The company’s specialists classify all frame-sheathing partitions into several standard types:
| Horizontal sectional view | Construction type |
| C 111 – frame made of steel profile, covered with 1 layer of plasterboard sheets. | |
 |
C 112 - steel frame covered with gypsum plasterboard sheets in 2 layers. |
 |
C 113 - a “single” frame made of steel profile covered with a three-layer gypsum plasterboard covering. |
 |
C 115 – KNAUF partitions this series have double metal carcass and 2 layers of sheathing made of gypsum plasterboard sheets. |
 |
C 116 – double steel frame with space for communications. The structure is covered with 2 layers of plasterboard on each side. |
 |
C 118 – “Intrusion protection”. The frame is made of steel profile and sheathed with gypsum board in 3 layers. Galvanized steel 0.5 mm thick is laid between the sheets. |
 |
C 121 – partition frame made of wooden beam covered with 1 layer of gypsum board. |
 |
C 122 – wooden frame with a two-layer gypsum plasterboard coating. |
For the external coating of frame structures, the KNAUF company produces a durable high-tech gypsum-based material that does not contain toxic substances, is absolutely non-flammable and has excellent performance properties. Drywall is produced in the form of KNAUF sheets (GKL) - rectangular elements consisting of a reinforced gypsum “core” covered with cardboard that has undergone special treatment.
Depending on the area of application, these sheets have different properties and are divided into types:
In addition to this classification, KNAUF sheets have differences in the type of side edge. All features of the material are indicated by markings that are applied to each sheet.
Features of the partition frame
Next constituent elements frame-sheathing structures of the KNAUF system are metal profiles - strips of galvanized steel with a thickness of 0.5–0.8 mm. These products add strength to the frame, but do not add to its overall weight. Let's consider what kind of profile is needed for a plasterboard partition, which will be made using the KNAUF system:
The design features of KNAUF systems require strict compliance with all manufacturer’s recommendations regarding their installation. The company's specialists pay great attention to the characteristics and quality of the fastening material that is used in the assembly of frame partitions and plasterboard.
To connect the profiles to each other, it is recommended to use screws (self-tapping screws) for metal LN 9 and LB 9 (piercing and drilling). For fastening Knauf sheets self-tapping screws of type TN and TB with a length of 2.5–4 mm are used. The guide profile is attached to the ceilings with simple or anchor dowels measuring 4, 6, 8 or 12 mm.
1 - LN screw; 2 - LB screw; 3 - TN screw; 4 - TB screw
The design of a partition made of plasterboard from the KNAUF system is very simple, and for its installation all you need is simple tool, which is included in any “home” set:
KNAUF specialists have developed step-by-step technology installations plasterboard systems, implying a strict sequence of execution of all work. So let's consider brief instructions for installation of plasterboard partitions:
This short review plasterboard systems developed by the famous German company KNAUF is a kind of instruction that must be followed when installing partitions. Additional questions issues that arise during your work will be carefully reviewed by our experienced specialists. Rest assured, we will give you an answer that will provide a “pleasant” result in such a difficult task as home renovation.
