Suspended ceiling made of plasterboard using Knauf technology. GKL ceiling using Knauf technology: basic manufacturing rules

During installation false ceiling the main wishes of the homeowner are to ensure that the structure is strong, durable and attractive, and the installation work does not take much time. Gypsum board ceilings Knauf technologies just meet all these requirements. Consider all the features of this technology in this article.

Briefly about Knauf technology

Knauf is a German development. Its developer is the Tigi-Knauf company, which produces high-quality materials for construction and repair - various drywall sheets, fasteners, profiles, etc.

Knauf is a variant of the manufacture of suspended structures using drywall sheets, which are mounted on a special suspension frame.

What should be the framework?

When assembling a frame for a suspended structure, the company recommends that the following requirements be met:

1. Use drywall sheets of its production, which have high moisture resistance.
2. Installation of profiles in a checkerboard pattern with an overlap or randomly so that the ceiling does not deform under the mass of drywall.
3. Connect profiles with Knauf fasteners.
4. Avoid joining sheets in the center of the opening so that the vibrations that occur when the door is opened do not provoke deformation of the coating.
5. After completing the installation of the frame, it should be finished using thermal insulation tape.

Self-supporting ceiling frame Knauf technologies mounted using special profiles marked CD and UD.

Pros and cons of technology

The advantages of ceilings using Knauf technology include:

1. Small time costs for the implementation of work. With all the right tools and sufficient qualification of the masters, installation can be carried out in one day.
2. The possibility of mounting such a ceiling in any room, regardless of size and configuration.
3. Ease of subsequent processing and it is possible to use any kind of material.
4. Successful leveling of various defects in the base ceiling and hiding communication lines due to the presence of a gap between the coating and the finished surface.
5. The presence of additional features in the form of laying on the ceiling of a layer of material for insulation or sound insulation.
6. Possibility to mount different variants designs. It can be single-level with spotlights or multi-level.

The only disadvantage of the technology under consideration is that when installing such a ceiling, the height of the room is significantly reduced. But this is a minus only in the case of small rooms, while for large rooms with high ceilings, on the contrary, this can be an advantage.

Preparation for installation work

Work on the installation of the ceiling in question should be carried out during finishing work. In this case, all wet work should already be completed.

It is important to pre-level all vertical surfaces.

It is important to create room temperature and humidity. The temperature in the room below 10 degrees Celsius is not allowed for work.

What will be required from the materials and tools?

Before starting work on installing the ceiling, you need to prepare the following tools:

• perforator;
• cordless screwdriver;
• drill;
• roulette;
• pencil;
• a knife with which you can process the ends;
• hydraulic level.

It will not be superfluous laser level, since the frame assembled according to the technology under consideration has a large number of constituent parts, the location of which should be strictly in level.

From the materials you will need drywall itself and frame elements - metallic profile or wooden beam.

In the manufacture of a frame from a metal profile, two types of guides will be needed:

• PN 27×28 - for installation along the perimeter of the room;
• PP 60 × 27 - for installing other frame elements.

Varieties of drywall

In relation to operating conditions, Knauf drywall can be of the following types:

1. BUT - standard drywall for construction. It can be used when installing in a room that is heated and has low humidity (up to 60%).
2. H2 - possesses the increased resistance to moisture. Can be used in rooms with humidity up to 75% due to low water absorption (up to 10%).
3. DF - flame resistant sheets.
4. DFH2 - combines the properties of drywall type DF and type H2.

Basically, the calculation of the frame is carried out taking into account standard sizes drywall 1.2 × 2.5 m and a thickness of 9.5 mm. However, drywall dimensions may vary.

The edge of drywall is mostly semi-circular thin, but some sheets have a different edge (straight, with a cut corner, thin, rounded one-sided chamfer or semi-circular).

However, the first type of lump is the most technologically advanced. Each of the other non-standard types of edges are designed to solve specific structural problems. For example, to mount corner protrusions.

What are ceiling structures?

Frame for stretch ceiling can be made using a Knauf metal profile or using wood bars.

Suspended ceiling can be 5 types:

1. P 111 - assembly of a biaxial frame is made from a wooden bar.
2. P 112 - assembly of a biaxial frame is made from a metal profile.
3. P 112 - assembly of a uniaxial frame is made from Knauf metal profiles.
4. P 131 - frame assembly by means of a light profile fixed to the walls.
5. P 19 - architectural and decorative design with the creation of a complex multi-level ceiling.

Step-by-step advice from technology developers, for those who want to do the work themselves.

More:

1. With the help of a level for control and a chopping thread along the perimeter of the walls, a line should be marked.
2. Given the type of drywall that has been chosen, you should mark the guides with dots for attaching hangers.
3. With the help of anchors or dowels, suspensions are attached in the designated places.
4. Subsequent work depends on the type of frame to be made - wooden or metal.
5. At wooden frame a beam is fixed to the base using a direct or quick-mounted (facilitates the possibility of an instant change of the mounting side) suspension. Next, the guide beam is fixed to the ceiling. Linings are used to reduce differences in the height of the base.
6. When mounting a metal frame, the profiles are connected by hangers with a 10 mm expansion gap, so that it is protected from temperature changes. At the same time, a sealing tape is laid under the guide profile. The profile used must be exclusively wall. One-piece rails are mounted on a long wall. Dowels are fixed at a distance of up to 30 cm from each other. The carrier profile must enter the guide by at least 3 cm.
7. After the frame is fully assembled, they proceed to sheathing it with Knauf drywall.

Mounting rails

To mark the ceiling mounted using Knauf technology, the usual building level won't be enough. The use of a hydraulic level or a laser device is recommended. You will also need to purchase a paint pad.

Having placed marks in the corners of the room by means of a hydraulic level, they are interconnected by means of a cord.

The profile is fixed under the intended line, while not forgetting that the ceiling will drop to the width of the profile + drywall sheet. Therefore, it is necessary to make calculations in advance so that the ceiling is not lowered too much.

On a note: When marking, you should determine the presence of electrical wiring on the walls and ceiling. The places where it is located are also marked so that the electrical wiring is not damaged during the fastening of the profile.

After marking is completed, the guides are fixed, represented by a profile of 27 by 28 mm. They are fixed to the wall with dowels 6 by 40 mm.

How is the finish made?

The main requirement for the installation of GKL using Knauf technology is the fastening of sheets across the supporting profile. Self-tapping screws should be screwed in at a right angle. Previously, the edge of each sheet, not glued with cardboard, is processed to remove the chamfer.

Work is carried out with an assistant or a special lifting mechanism. According to the rules, the sheets are fixed in a checkerboard pattern or in a run. In the longitudinal direction, the sheet must be laid without a gap; in the transverse direction, a small gap is formed. This is the only way to achieve a perfect seam after the gap has been puttied.

It is important to take into account the possibility of the influence of temperature differences on the finishing surface, under the influence of which it can expand and deform. If special expansion joints are provided in increments of 15 cm, serious deformation will be excluded.

Self-tapping screws must be screwed in so that they sink into the coating sheet by about 1 mm, so their hats will not be visible on the surface. To seal the joints, reinforcing tape is used.

Step by step finishing

When designing and installing ceilings of the technology in question, which have two levels, it is necessary to make the material stronger by applying a finish based on moisture-protective compounds and putty mixtures.

Seams are masked as follows:

1. With a narrow spatula, the joints are filled putty mixture, the rest of which is removed.
2. Seam tape attachment.
3. Coating the tape with putty and removing residue after 45 minutes or more.
4. Screw head putty.
5. Re-filling the seams and removing residues with an already wide spatula.
6. Surface grinding.
7. Installation of an aluminum corner or PVC corner in place of the outer corners.
8. fastening between inside corner and GKL separating tape. Surface coating with putty.
9. Painting and plastering of the material after its complete drying.

Features of fastening drywall to the frame

More:

1. Plasterboard sheets must be fixed in the direction of all profiles using self-tapping screws. The latter should be located at a distance of no more than 20 cm from each other. Where the sheets form joints, the self-tapping screws are placed with an offset.
2. Cutting a straight part from this material can be done with a sharp knife. After notching the top layer, the sheet may be broken along the slit. If it is necessary to prepare figured parts, it is better to cut them with a hacksaw.
3. Screwing in screws must be done with care. The hat needs to be drowned a little in the material, but it should not be broken through with a self-tapping screw, because in this case the fastening will not be reliable.

GKL, also known as sheet gypsum cardboard, is a fairly cheap material based on cellulose and gypsum. It is lightweight, easy to mount on any plane (using aluminum profiles). Directly during its installation, a small indent from the base of the plaster is made. If necessary, the lines are aligned along the perimeter, which makes it possible to hide the visual defects of the main ceiling without parsing it.

The most best technology installation of sheet drywall on the ceiling is the application of the KNAUF system. That is, fixing each sheet separately on a pre-mounted aluminum profile. That, in turn, can be rigidly attached to both the walls and the main ceiling.

Hangers on belts are made if necessary (for example, if the length of each span is more than 4-5 meters).

It should be mentioned that the GCR is allowed:

• paint;
• cover with trim;
• cover with PVC film;
• bleach.

Mounted box of plasterboard on the ceiling

What will the mounted box give? Possibility to create a two-level . In one of the parts (the base of which will be below) you can mount all the necessary lighting. Other communications (cable for the Internet, meter output) will also fit there without any problems. The hardest part is the calculation. Installation implies that the first level will be completely fixed initially. From above - the boxes are fastened along the new guide profiles.

It should be borne in mind that the final mass of the structure will turn out to be quite large, so additional fastening must be provided in advance.

But for this purpose, the best fit:

1. partitions (in compliance with SNiP);
2. fake lining, behind which the hats of self-tapping screws are hidden;
3. hard binding of the second level.

Which of the options would be ideal for a given situation? It is better to entrust this choice professional builders or designer.

Painting plasterboard ceiling: options

Painting ceilings based on drywall sheets is best done with paint on water based(emulsion). Its key advantage is absorption into the cellulose base. Accordingly, in the future it will not fade under the sun's rays, do not increase the surface roughness. It also has similar properties acrylic paint, but it should not be used indoors. In addition, painting should be done with a spray gun, and not with traditional rollers. After the latter, visually noticeable dents will remain.

Is it necessary to paint plasterboard ceilings at all? This gives several advantages:

• great mechanical stability;
• protection from insects (if any are found in the house at all);
• steam waterproofing.

The disadvantages can only be attributed to the fact that re-painting will have to be done every 3-5 years. And if with ordinary ceiling there will be no problems, then at two levels you will have to tinker a lot.

GKL or GVL for the ceiling: differences

GVL, also known as gypsum fiber, is the same drywall, but also produced using a slightly different technology. Its thickness is almost the same, but it is used mainly in those rooms where there are increased requirements for fire safety. And them exterior finish not recommended. However, many manufacturers, even in factory conditions, decorate such sheets with figured cutting and carving.

Detailed differences between moisture-resistant GVL boards are presented in the article:.

Advantages of GVL:

1. reliability;
2. higher moisture absorption coefficient (up to 12 liters per square meter);
3. absolutely smooth surface.

GVL sheets are also mounted on a pre-installed metal frame made of profiles. The fastening device is identical to that used with drywall (Knauf).

Do-it-yourself installation of plasterboard on the ceiling

Do-it-yourself installation of GKL is not difficult. The main task for a specialist is to determine the nominal level of fastening profiles. As a rule, the indentation is from 3 to 10 centimeters. If it is planned to install lamps or equip all this with lighting, then the distance can be increased. If at the top is wooden ceiling, then it is recommended to knock it out with a layer of fiberboard.

Even in the event that it is planned to make two-level ones, the first step is to completely set the first level (with a solid canvas). The box is stuffed already on this layer. A simple calculator and a few mathematical formulas will let you know exactly how much all this material will require.

Detailed instructions for creating two-level ceilings in material: .

The procedure for installing the ceiling from the plasterboard:

• markup;
• plaster of the main ceiling;
• installation of aluminum profiles that will hold the structure;
• alternate installation of sheets;
• installation of cornices at the base of the walls.

In more detail, this process can be seen in the photos and videos below.

Option: plasterboard ceiling using Knauf technology

Using the Knauf system, you can also create a so-called floating ceiling, that is, which is not attached to the walls around the perimeter. On the sides, as a rule, LED backlighting is attached there.

The soaring ceiling mount rests on:

1. profiles with elongated edges;
2. belts;
3. beams (if necessary).

Suspended ceiling from Knauf sheets (video)

What is the advantage Knauf systems? In that it fits any home, while after the installation of the ceiling it will not be noticeable at all. This also applies to the installation of GVL sheets.

P 131. Construction on metal frame, single-level. Unlike other complete systems, the frame consists of profiles of partition systems and is attached not to the ceiling, but to the enclosing structure of the room (walls). It is recommended to make such ceilings in rooms with limited height.

Knauf sheets

Knauf sheets have a number of unique properties thanks to which they can be used in rooms of different functionality. Applications: business class commercial buildings, residential luxury houses, educational institutions, medical centers, cinemas, high category hotels.

Gypsum building stove Knauf(gypsum board, KNAUF-GSP) is made in the form of a rectangular two-layer cardboard construction. Between the layers of cardboard there is a gypsum core containing impurities in the form of reinforcing components.

The applied facing cardboard is used as a reinforcing frame, it is harmless and recommended for use in residential premises. At the same time, the cardboard has an increased weight, thanks to which the front side of the sheet becomes ideal for decorative finishes High Quality.

The gypsum core inside the cardboard sheets is non-flammable, fire resistant, non-toxic, and does not emit environment harmful substances.

Additives mixed with gypsum binder increase the overall strength, density, and other performance properties of the material. In addition, special adhesive components ensure tight adhesion of gypsum and cardboard.

Installation instructions

Determine the type of future ceiling - focus on the indentation from the ceiling, the height of the room, the functional tasks of the ceiling.

Choose the type of frame - single-level or two-level.

Mark the level.

Assemble the frame from the ceiling metal profiles.
Pin elements engineering communications(if necessary).

Install drywall sheets.

Seal the seams between the sheets with universal gypsum putty with paper reinforcing tape. Or putty Knauf-Uniflot without the use of tape.

Knauf ceilings are considered the most popular in our time, because with their help you can seriously transform the ceiling surface of any interior. In this article, we will try to adequately answer questions about how the ceiling is installed according to the Knauf system, and also what is routing Knauf and tell about its purpose.

When installing a plasterboard ceiling, you need to follow some instructions that will help you do the job efficiently and correctly. They differ little from the requirements for standard installation plasterboard ceilings, but have their own characteristics.

Mounting Features suspended ceilings from GKL according to the Knauf system:

• Ceilings can be installed on an unprepared ceiling surface.
• Ceilings of the Knauf system are installed on ready-made ceilings finished with plasterboard.
• Application of the system is possible on metal, wood and already covered with materials frame.

Marking the plane of suspended ceilings

Having determined the materials and tools for mounting decorative trim, we need to correctly mark the ceiling plane. According to the requirements of the technology, it is necessary to retreat from the finished ceiling at least 10 - 12 cm, because this distance is necessary for the installation of special load-bearing suspensions, laying communications, installing decorative lamps, etc.

Marking is carried out along the perimeter of the walls, using a water or laser level, as well as dyeing laces, which will put even lines on the surfaces.

After marking the walls, we understand at what level the Knauf plasterboard ceiling will be located, but now we need to make markings for the supporting metal profile, on which the sheets will be fixed.

The longitudinal bases of the frame are marked in steps that depend on the load of the ceiling, but it is most correct to place them at a distance of 60 cm from each other. The transverse bearing profile is marked with the same step, but the distance may vary, depending on the requirements of the technology, the weight of the ceiling, subsequent finishing, decorative finishing and other parameters.

Frame device

The frame for the plasterboard ceiling made of a metal profile is mounted on the walls and on the ceiling. Initially, along the lines marked on the walls, we install the carrier profile. Further, according to the markings on the ceiling, with the help of rods and suspensions, we install the main carriers of the ceiling frame. Here it is very important to work correctly with the length of the profile, its uniform laying in relation to other parts of the frame, as well as its level. To do this, you can use leveling threads, a laser or magnetic level.

It is very important to know that the profile can always be cut or lengthened, pulled up or lowered from the ceiling, the main thing is that the frame is in a single plane, which will allow further work build a really smooth and beautiful ceiling.

Stiffening ribs, or a transverse support profile, is installed on the main carriers using a single-level connector, which is very simple, since special fasteners easily snap into place on the profiles. After its installation, it is necessary to check all levels, and if the work is of high quality, fasten the longitudinal and transverse profiles together with metal screws.

sheathing

Knauf ceiling technology does not imply simple sheathing, but according to mandatory requirements that will improve the quality finished construction and ensure its reliability.

• So, each piece of gypsum must be cut correctly using a special tool. It is also necessary to make a chamfer with outer side, which will be further sealed.
• All sheets for plasterboard ceiling Knauf are installed in a run-up with a step in the transverse fastening of the profile. Most often, this is a standard step of 60 cm. This is necessary to strengthen the plane and to avoid cruciform joints, which, one might say, are even prohibited when installing GKL sheets on a profile.
• Gypsum should be mounted on the frame with a certain gap between the pieces, which should be 5-7 mm. This will help remove the mechanical load from the sheets and prevent cracks and chips, which often appear when ceilings and walls are incorrectly finished with gypsum.
• Sheathing occurs with standard self-tapping screws, in increments of 20-30 cm, depending on the requirements and load of the structure. Sheathing can be done with a mechanical, electric or pneumatic tool, depending on which one you have access to.

Suspended ceilings from drywall Knauf can be laid with special materials from the inside to ensure energy saving and increase the sound insulation of the room in which the decoration takes place. Can be used for insulation special materials or the standard mineral wool with which we are already accustomed to work. It can also act as soundproofing for the Knauf ceiling, but a sealing tape for a metal profile will also help to ensure it.

Finishing work

Suspended ceilings of the Knauf series are provided for a variety of finishes, and therefore they can be covered with wallpaper or painted with your chosen paint. Also, the ceiling plane can be finished with other materials, but the possibility of this should be provided for even before the start of installation, because not only the requirements of the room where the work takes place are important here, but also the conditions for the production of the ceiling, which directly depend on the size of the finishing material, its weight and the weight of the subsequent decoration.

Decorative finishing occurs necessarily after plastering or puttying the plasterboard ceiling.

Technological map Knauf

Typical technological map for Finishing work with the use of complete Knauf systems was developed for ease of compliance right technology ceiling structures. Integrated systems help installers to calculate required amount material for the ceiling of the plasterboard, drawing up a map - drawing and proper assembly of the structure.

The purpose of a typical technological map is the development of projects for the work performed with gypsum plasterboards, the organization of the construction of structures. In addition, the technological map is an information tool for professionals involved in the installation of suspended plasterboard ceiling structures.

The Knauf technological map has a number of specific requirements that must be observed during the production of work, indicates the consumption of materials for different sizes erected structures and the exact order of work during installation.

Suspended ceiling according to the Knauf system - interesting job and the ability to qualitatively diversify and provide the most exclusive projects, because you can always work not only with single-level and multi-level ceilings and planes, but also use interesting architecture in your work. If you work with drywall regularly, the technological map developed according to the Knauf system will be an excellent assistant in your actions and undertakings.

Complete systems Knauf (video)

The use of Knauf technology for the installation of a false ceiling made of plasterboard guarantees the strength and durability of the structure. This German development which uses only the highest quality materials. Despite their popularity, they are quite reasonably priced.

In Russia, they are actively used in the decoration of residential premises, office and industrial construction. The method does not require much time, and the result is excellent.

Necessary materials

Required to complete the work ceiling drywall and frame elements (wooden beam or metal profile). You also need fasteners (self-tapping screws, dowels), crabs, various hanging elements.

In addition, you will need a set of tools. It includes:

• hydraulic level;
• pencil;
• roulette;
• drill;
• cordless screwdriver;
• perforator;
• a special planer for processing the edges of the sheet;
• knife for metal for processing ends or grinder;
• laser level;
• paper reinforcing tape.

Advantages and disadvantages

The technology has many advantages:

1. Variability. It is possible to perform different design options (single-level or multi-level).
2. Creating ceilings various forms according to the drawings of designers, the ability to adjust the height of the ceiling and hide flaws.
3. The ability to lay layers of material on the ceiling for additional sound insulation and insulation. This will save energy and provide good conditions for living.
4. Ease of processing.
5. Drywall is an ideal material for installing recessed spotlights.
6. The ability to use any materials.
7. Small time investment (work can be done in one day).

Of the minuses, only a significant decrease in the height of the room after the installation of the ceiling can be noted. But this actual problem only for small spaces.

Peculiarities

The use of this technology implies the presence of some features that you need to know. More about them:

1. The system can be applied to the following types of frames: metal, wooden, covered with materials.
2. Sheets are fastened in the transverse direction relative to the carrier profile.
3. Mandatory processing of drywall sheets with chamfer removal.
4. Work is carried out using a lifting mechanism, or with an assistant.
5. Provide expansion joints in increments of fifteen centimeters so that the finishing surface does not deform due to temperature changes.

Preparation of conditions for installation

Before starting installation, it is necessary to complete all the work on finishing and leveling the walls. An important condition is to maintain a normal or dry humidity regime. In no case should the room temperature be below 10 degrees, the optimal range is 15-20 degrees. If work is carried out in winter time, then you should take care of heating in advance.

Very milestone- performing the correct marking around the perimeter of the walls. To do this, you will need to retreat from the finished ceiling by about 10-12 centimeters. The frame should be installed as accurately as possible, as it will serve as a starting point.

If a laser level is used in the work, then it will be very easy to cope with the task. Using a hydraulic level, two points should be marked on one of the walls and connected with a chopping cord. A similar procedure is repeated on all four walls in the room. In no case should communications interfere with work. Otherwise, they can be easily damaged by a sharp corner of the profile or by an incorrectly driven nail.

Frame installation

The Knauf company has released special brochures that describe in detail all the processes for installing plasterboard suspended ceilings according to their technology.

A number of holes are drilled according to the marked lines. Dowels are hammered into them and guide elements are installed to make the base. They will serve as a support, and their location determines the position of the ceiling plane.

Before installing the transverse and longitudinal frames, markings are made and U-shaped suspensions are attached. Optimal distance between fasteners is considered 40-50 cm.

The next step is the installation of the elements of the crate. Here you will need the use of suspensions and guides around the perimeter.

sheathing

At the end, the frame is sheathed with plasterboard sheets. Knauf technology requires compliance mandatory requirements to improve the reliability of the design. Here they are:

1. Competent cutting of pieces of gypsum into fragments desired shape special tools.
2. Installing drywall sheets in a run-up in compliance with a certain step. This action helps to strengthen the plane and prevents the formation of cruciform joints.
3. Mounting plaster on the frame in compliance with the gaps (5-7 mm each). This prevents the appearance different kind damage.
4. During the work, standard self-tapping screws are used. They must be screwed in carefully so that the sheet does not tear.

Seam sealing

• surface preparation (removal of dust that prevents high-quality adhesion of materials);
• priming seams (for good adhesion);
• laying putty between the seams;
• applying the first layer of putty directly to the seam;
• sealing the seams with a special tape with a reinforced action (press into the putty layer, holding it in a taut position);
• rubbing the dried layer of putty with sandpaper;
• applying a second layer of putty;
• grinding (to give a holistic, monolithic ceiling).

Proper sealing of joints is very important and sets the strength of the structure.

Finishing

When the surface is ready, you can veneer it with almost any finishing materials. Most often they are pasted over with wallpaper or covered with paint, but if desired, other options can be considered.

Installing a plasterboard ceiling using Knauf technology is not difficult if you follow the instructions clearly. Having the necessary skill and basic skills in handling tools, it is quite possible to do the work with your own hands.
