Application

Description

The Knauf P 112 complete system is a complete set of specially selected materials needed to create a false ceiling on a two-level metal frame. The finished ceiling structure is not a structural (bearing) element of the building.

The main building elements of the ceiling:

plasterboard KNAUF sheet;
metal KNAUF ceiling profiles PP 60x27.

The complete composition of the complete system and the required amount of materials per 1 sq. ceiling meter, see "Technical data".

Distinctive features of this system: the main profiles of the suspended ceiling frame, fixed using suspensions to the base ceiling, and the supporting profiles to which the Knauf plasterboard is attached, are located at different levels.

In addition to the main elements, the complete system includes the technical solutions necessary for solving a specific construction task, recommendations for the performance of work, as well as tools and fixtures.

All elements of the P 112 complete system are manufactured using modern technologies, undergo strict quality control, are functionally oriented and, as part of the complete system, ensure the reliability of the entire structure during long-term operation.

Application

Application area

It is used in premises for various purposes, both during reconstruction and in new construction in order to:

finishes;
solving structural and planning problems;
elimination of irregularities in the overlap;
hidden placement of engineering communications;
increase the sound insulation of floors;
acoustics;
increasing the fire resistance of ceilings and coatings.

Mounting process

The installation process includes the following stages of work:

marking the design position of the suspended ceiling frame;
assembly and fastening of the frame;
installation of KNAUF plasterboard sheets (GKL) in the design position and fastening to the frame;
sealing joints between Knauf plasterboard sheets and, if necessary, continuous puttying of the suspended ceiling surface;
priming the suspended ceiling surface before applying paint or decorative coating.

Installation of suspended ceilings should be carried out during the period of finishing work (in winter with heating connected), before the installation of clean floors, when all the “wet” processes are completed and wiring of electrical and plumbing systems has been completed, in dry and normal humidity conditions in accordance with SP 50.13330.2012 Thermal protection of buildings. Updated edition of SNiP 23-02-2003. In this case, the temperature in the room should not be lower than 10°C.

In conditions of high humidity (bathrooms, kitchens), it is recommended to use moisture-resistant KNAUF plasterboard sheets (GKLV).

The location of electrical wiring in the space of the ceiling frame should exclude the possibility of damage to them by the sharp edges of the frame elements or screws during the fastening of drywall sheets.

Advantages

The complete system P 112 allows you to most correctly, efficiently and economically solve a specific construction task - the creation of a suspended ceiling.
In the process of creating a false ceiling, uncomfortable "wet" processes are excluded.
Significantly increases labor productivity.
Achieved overall savings in construction costs by lightening the structure of the building.
It is possible to implement unlimited in design, multi-variant architectural solutions for ceilings.
The finished ceiling has a high level of quality of finished surfaces.
The surface of suspended ceilings P 112 is suitable for any finish: painting, wallpapering, decorative plastering.
The heat and sound insulation qualities of the room are improved.
Not only environmental cleanliness is ensured, but also a microclimate in the room that is favorable for humans. Since the main material of the complete system - KNAUF gypsum board sheet - has the ability to breathe, that is, to absorb excess moisture and release it into the environment if there is a shortage.

Knauf is a leader in the production of gypsum plasterboard materials for dry construction. The advantages of the product include the possibility of using it for various purposes: arranging walls and ceilings, protecting against fire or moisture, enhancing the heat and sound insulation qualities of the treated surface.

Types of Knauf gypsum boards

Among the differences of the brand is the release of additional components - screws, profiles, and finishing materials - primer, putty, plaster mixtures, etc., which, in combination with drywall, form a reliable, durable and durable coating.

To avoid the problems that arise when choosing and using these materials, the manufacturer Knauf provides a special instruction for the installation of gypsum boards with a description of all the nuances of the work.

Knauf identifies several requirements that a frame for walls, partitions or under a suspended ceiling must have before sheathing begins. These include:

To protect the material from the influence of dampness when the profile freezes, sheathing should be carried out using Knauf GKVL;
To exclude deformation of the structure under the weight of drywall, long sections of the profiles are set apart or staggered with an overlap;
As a connector of the frame elements, a cutter (with a bend), an LN9 screw or a Knauf brand screw is used;
To protect the material from deformation under the action of vibrations created by the door and its weight, it is forbidden to join the GKL in the middle of the doorway;
After assembling the frame, it must be finished with thermal insulation tape.

The Knauf frame system is assembled from profiles of a certain format. Its choice depends on the type of work performed.

Types of Knauf profiles:

UD - guide for ceilings;
CD - ceiling carrier, forming a crate;
CW - bar for forming racks;
UW - guide for the device of partitions, walls.

Rules for installing gypsum boards on walls and partitions

The frame for a wall or partition made of plasterboard serves to provide additional heat and sound insulation, leveling, masking communications.

General points:

Use pin dowels Knauf K6/35 as a fastening element of UW guides to the base of walls and ceilings, allowable distance between them is 1 m;
As an element for fixing the CW profile to the load-bearing wall, use straight hangers, counting 1 pc. per 1.5 m of rack length;
The CW profile pitch is 60 cm;
For cladding walls and partitions, a plasterboard sheet of 2500x1200x12.5 cm format is used;
For decoration under tiles or artificial stone, a two-layer sheathing is used;
In places where the profile contacts the walls and ceiling, a soundproof tape is mounted;
The distance between the screws when sheathing is 25 cm;
To the frame of the walls and to the straight partition, the GKL sheet is attached vertically, for figured and radius structures - horizontally and by bending.

Rules for the device and ceiling sheathing

The suspended ceiling system of Knauf profiles and drywall is used to level, decorate, reduce the height of the room, and hide utilities.

Basic provisions:

Between the UD profile and the base of the ceilings, install a sound insulator (tape - self-adhesive brand Knauf);
Use a pin dowel as a fastener for the UD profile (1 pc. for every 50 cm);
Suspensions are installed at a distance of 90 cm along the line of attachment of the carrier profile;
The step between the supporting profiles is 40-50 cm, it is inserted with the base of the backrest to the sidewall of the UD plank and fixed to the ceiling with a suspension;
The distance between the screws for arranging the ceiling sheathing is 17 cm.

Mounting the GKL sheet to the ceiling starts from the corner of the room

Work with GKLV:

To cut niches, openings, holes for sockets, drywall / wood crowns, Knauf cutters for round holes or manually with a chisel are used;
Before sheathing, a chamfer is removed from the edge of the drywall sheet: if Fkugenfüller putty is subsequently used, the chamfering angle is 45 degrees, if Uniflot is 22.5;
To fix the skin to the metal frame, fixing screws with a length of 25 mm are used;
They begin to fasten the GKLV sheets to the frame with self-tapping screws from the center or corner, this will protect the material from deformation during the fixation process;

The sheets are installed close to each other, the edge of the plate is located in the middle of the CW or CD profile.

The position of the GKL sheet relative to the profile

Below you can see how the frame for partitions is installed and sheathed with Knauf materials.

Finishing work

At the end of the sheathing, the manufacturer proposes to enhance the properties of GKVL by additional surface treatment with water-repellent compounds (Tiegenrund primer) and Uniflot or Fugenfüller putty.

Seam sealing:

Filling the joints with putty using a narrow spatula, removing residues and excess thickening of the mixture;
Seam tape installation;
Covering the tape with a thin layer of putty, after 45 minutes removing residues from its surface;
Puttying of screw heads;
Secondary filling of the seam with a wide spatula, removal of residues;
Hand sanding to eliminate irregularities;
Installation in the area of outer corners of an aluminum square, PVC corner or aluminum tape, puttying;
Installation of the Knauf separating tape between the drywall sheets and the inner corner, puttying;
After drying, the material is painted and plastered.

Subject to all the requirements and recommendations, the installation of partitions, walls or ceilings using Knauf materials will be successful and durable. But remember, when doing: the smoother you set the structure of the profiles, the smoother the surface will be in the end.

In contact with

Knauf suspended ceilings are known to many people in various countries. They got their name from the name of their fairly well-known German manufacturer "Tigi-Knauf". Thanks to a special production technology, Knauf "suspended ceiling" complete systems combine aesthetics, ergonomics and simplicity, coupled with a reasonable price. Knauf suspended ceilings are a subspecies of plasterboard ceilings, therefore they have some of its advantages and disadvantages. Many mount them at work or at home, they are often used in industrial construction.

In our article, we will consider the main thing, paying attention to the advantages of this type, its features, tips on, the installation process itself and the materials necessary for this. We remind you that carefully selected photos are presented specifically so that you can understand the essence of the article as best as possible, do not neglect to consider them.

Advantages of the Knauf ceiling

Plasterboard structures as such make it possible to adjust the height of the ceiling and hide communications underneath, as they can form multi-level structures at some distance from the base ceiling. Actually, that is why Knauf ceilings can be called suspended. But one of the most important advantages remains that with the help of sheets you can create structures of various shapes, including spherical and cone-shaped. Drywall also supports tie-in fixtures.

If you choose the right insulation, then such a ceiling will be indispensable and will serve you for a long time. In the kit you get the drywall sheets themselves and the metal profile, which is necessary for installing the first ones.

Before starting work on the installation of GKL - drywall sheets - it is necessary to complete all finishing work, in particular on the walls. Don't leave to last any work that involves interacting with water. Naturally, before finishing the walls, they should become even and clean, so take time for this as well.

The installation itself should be carried out at a temperature of 10 degrees Celsius and above, and the best option would be to maintain an average temperature of 15-20 degrees. Therefore, as a last resort, when work takes place in winter, take care of heating for the room. This will help both people and materials to be in shape. Speaking of humidity levels, don't forget that dry mode is the most preferable, but normal mode is also acceptable. You can learn about how the level of humidity is delimited from SNiP 23-02-2003 "Thermal protection of buildings".

After all the above conditions are met, it is necessary to accurately mark the ceiling, taking into account the pitch for the ceiling and the type of load for attaching the hangers. That is, on the ceiling it is necessary to mark with a pencil the location and sheets of drywall. Do not forget that those communications that you plan to hide under the ceiling must be carried out immediately after marking.

Necessary materials for installation and their types

When using sheets from the manufacturer Knauf, the installation of the ceiling should be carried out with the participation of 10, and sometimes more, different elements.

Let's see which ones:

The required amount of material for the installation of drywall

The ceiling according to the Knauf system is usually quite heavy, because a large number of elements are involved in the repair (see also: ""). You yourself could see it by reading the previous subheading. And it is very important to buy the necessary amount of material in advance so that it is enough for the entire time of work. Our list of materials that are needed to fix the GKL on 1 square meter will help you with this.

The average consumption of materials that will be needed during the installation of the entire ceiling is given:

All of these materials are very important for the successful completion of the work. But do not forget that in this table we have not given the quantities of some other materials that will be needed only under certain conditions or on one section of the ceiling. So, these include fasteners, connectors, guide profiles and self-tapping screws.

How to install a Knauf false ceiling, in detail on the video:

Knauf suspended ceiling installation

Now we will consider the installation process of the Knauf false ceiling, which consists of many parts:

Preparing the right tools . Not a single builder can do without them, so take care of the timely acquisition of the missing ones. So, to install the Knauf ceiling, we need a puncher, a screwdriver (preferably on a battery), metal scissors or a grinder, a paint chip with paint, a tape measure, a level, a marking cord, a knife for cutting drywall sheets and a special planer for processing the edges of the sheet. Read the list carefully a couple of times so you don't accidentally miss an important item. Do you have everything? If yes, then you can proceed to the next step.
Ceiling markings . At this stage, a level and lace will come in handy. It is necessary to beat off a line along the entire perimeter of the room on the walls, corresponding in height to the lowest section of your ceiling. This can be done, for example, by marking 4 points on the walls on all sides with a level, and then connecting them with a cord. For the future, remember that from the marked line, the finished ceiling will fall by 4 centimeters, no less. This will happen due to the mounting of rather massive profiles and sheets. And do not forget that communications that have already been made should not interfere with work, otherwise they may be damaged by an incorrectly driven nail or a sharp corner of the profile.
Installation of the frame of the crate . First, according to the markup carried out at the very beginning, we fix the guide profiles in any reliable way. After that, the Knauf 60x27 ceiling profile is mounted in increments of about 40 cm. We connect the profiles that are at right angles to each other with a crab connecting element. Special clamps are fixed in the profile cavity in such a way that the fastening snaps into place. The crab is installed using LN self-tapping screws with dimensions of 3.5x9.5 mm. By the way, they are also called bugs or fleas. After that, we get a high-quality crate with a cell of 40x40 cm.Further, according to the markup, we install suspensions and fix them on the concrete surface of the ceiling with the help of dowel-nails. If the material on the base ceiling is softer than concrete, then it is acceptable to replace the dowels with screws. By adjusting the length of the suspensions, we make sure that the entire structure is located on the same plane, check this with a level.
Sheathing the frame with sheets . For this step, we also need self-tapping screws, but already others - TN with dimensions of 3.5x25 mm. They are screwed strictly perpendicular to the sheets and must go deep into the profile by at least 10 mm. On the other hand, the head of the screw should not go deeper into the surface by more than 1 mm. But in no case should she act, so try to fix her in the optimal position - pressed in quite a bit.You need to screw in the screws either starting from the center to the corners or diagonally - from one corner to another. The sheets should overlap the profile by three millimeters, and the joints of the end edges relative to each other should be spaced apart and at a distance of at least a profile step of 0.4 m. thirds of the thickness of the sheet.Next, a layer of gypsum putty is applied inside the joint using a narrow spatula. Excess should be smeared on the sheet near the joint. A sickle is glued over the smeared joint in such a way that the seam is covered on both sides by more than 100 mm. The surface of the film should be slightly pressed into the dry putty layer, but at the same time it must remain perfectly even, without bumps and deflections.
Seam sealing . The final step is to tidy up the rest. With a wide spatula, you should remove all the drips and putty spots that you find on the ceiling. Then they should also put putty on most of the sheet, as far as the width is enough. Our goal is to equalize the bump of the reinforcing tape with the sheets as much as possible using putty. Therefore, it is not a fact that everything will be covered from the first layer.

Thus, in this article, we were able to consider in detail the suspended ceiling according to the Knauf system and everything related to its installation (read also: ""). We hope that these tips will help you make repairs in your home in the best possible way, so that it will serve you for a long time and always please the eye!

The complete composition of the complete system and the required amount of materials per 1 sq. ceiling meter, see "Technical data".

A distinctive feature of this system: the main profiles of the suspended ceiling frame, fixed using suspensions directly to the base ceiling, and the supporting profiles to which the Knauf plasterboard is attached, are located on the same level.

All elements of the P 113 complete system are manufactured using modern technologies, undergo strict quality control, are functionally oriented and, as part of the complete system, ensure the reliability of the entire structure during long-term operation.

Application

Application area

It is used in premises for various purposes, both during reconstruction and in new construction in order to:

finishes;
solving structural and planning problems;
elimination of irregularities in the overlap;
hidden placement of engineering communications;
increase the sound insulation of floors;
acoustics;
increasing the fire resistance of ceilings and coatings.

Mounting process

The installation process includes the following stages of work:

marking the design position of the suspended ceiling frame;
assembly and fastening of the frame;
installation of KNAUF plasterboard sheets (GKL) in the design position and fastening to the frame;
sealing joints between Knauf plasterboard sheets and, if necessary, continuous puttying of the suspended ceiling surface;

See the Download section for details.

Advantages

The complete system P 113 allows you to most correctly, efficiently and economically solve a specific construction task - the creation of a suspended ceiling.
In the process of creating a false ceiling, uncomfortable "wet" processes are excluded.
Significantly increases labor productivity.
Achieved overall savings in construction costs by lightening the structure of the building.
It is possible to implement unlimited multi-variant architectural ceiling solutions.
The finished ceiling has a high level of quality of finished surfaces.
The surface of suspended ceilings P 113 is suitable for any finish: painting, wallpapering, decorative plastering.
The heat and sound insulation qualities of the room are improved.
Not only environmental cleanliness is ensured, but also a microclimate in the room that is favorable for humans. Since the main material of the complete system - Knauf plasterboard sheet has the ability to breathe, that is, to absorb excess moisture and release it into the environment in case of deficiency.

The use of Knauf technology for the installation of a false ceiling made of plasterboard guarantees the strength and durability of the structure. This is a German development that uses only the highest quality materials in its work. 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

To perform the work, ceiling plasterboard and frame elements (wooden beams or metal profiles) are required. 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:

Variability. It is possible to perform different design options (single-level or multi-level).
Creation of ceilings of various shapes according to the drawings of designers, the ability to adjust the height of the ceiling and hide flaws.
The ability to lay layers of material on the ceiling for additional sound insulation and insulation. This will save energy and provide good living conditions.
Ease of processing.
Drywall is an ideal material for installing recessed spotlights.
The ability to use any materials.
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 is an actual problem only for small rooms.

Peculiarities

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

The system can be applied to the following types of frames: metal, wooden, covered with materials.
Sheets are fastened in the transverse direction relative to the carrier profile.
Mandatory processing of drywall sheets with chamfer removal.
Work is carried out using a lifting mechanism, or with an assistant.
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, then you should take care of heating in advance.

A very important stage is 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. The optimal distance between fasteners is 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 with mandatory requirements to increase the reliability of the design. Here they are:

Competent cutting of pieces of gypsum into fragments of the desired shape with special tools.
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.
Mounting plaster on the frame in compliance with the gaps (5-7 mm each). This prevents any kind of damage.
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 look to the ceiling).

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

Finishing

When the surface is already 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.
