Rules for installing Knauf profiles. Partition standards according to the unified Knauf classification

12.06.2019 Boilers

An important element The walls and partitions of any house are considered. Without them it will not be possible to divide the building into separate rooms. Particularly in demand today are Knauf partitions, which are steel frame and plasterboard sheathing. This popularity is due to the excellent quality and affordable cost of the products. All its characteristics comply with European standards, and installation is so simple that anyone can handle it.

Advantages

Knauf partitions have found their application due to their advantages:

  • ease and speed of installation (assembled element by element);
  • ease of repair (the finished wall can be quickly disassembled and moved to another location);
  • low cost;
  • absence of “wet” processes;
  • reliability and durability.

These partitions have also gained popularity among consumers due to other qualities:

  • the ability to use the structure in regions with seismic hazard;
  • high quality products;
  • opportunities to lighten the building;
  • general savings on construction;
  • diversity architectural solutions(curvilinear forms can be erected);
  • the ability to obtain a structure with increased fire resistance, sound insulation, and moisture resistance;
  • environmental friendliness;
  • variety can be covered with paint, wallpaper, decorative plaster).

Installation of partitions “Knauf”

As mentioned above, this system consists of plasterboard panels, internal filler and fasteners. Additionally, it can be equipped with specialized plates that have increased fire protection. The covering can be one-, two- or three-layer. In this case, plasterboard, hyposavo fiber or aqua panels are usually used.

As for them, they come in guides, rack-mounts and load-bearing types. Together they form a frame, with each element having standard length- 3 or 4 meters.

If necessary, the profiles can be lengthened by overlapping them. They are fastened with self-tapping screws: four on each edge and two in the middle. Outer side the guide element is covered with insulating tape. Self-tapping screws are placed on it every 300 mm (maximum pitch - 1000 mm). TO load-bearing structures the partitions are secured with dowels.

Varieties

Depending on the purpose and device, Knauf partitions are divided into types: W111, W112, W113, W118. The W111 system is a frame covered with single-layer material on both sides. Sound insulation is placed inside it. The guides are attached to the supporting structures using dowels. After attaching the drywall, the joints between the sheets are filled special composition.

The W112 partition includes a frame, two layers of sheathing on both sides and sound insulation between them. The structures are also fastened with dowels, but additional fixation of the second layer of sheathing is necessary. This has a positive effect on fire resistance and sound insulation.

The W113 structure consists of a frame and three layers of skin (on both sides). There is non-flammable sound insulation inside. Such a wall has serious cladding, so it must be fastened at a maximum interval of 50 cm.

The W118 partition has the same structure as the previous design, but it is reinforced with a galvanized sheet 0.5 mm thick. It is also equipped with a reinforced profile frame, 0.6 mm thick. The article presents drawings of Knauf partitions and how they are attached.

Profile types

Depending on the purpose, Knauf profiles are divided into rack-mount, guide and arched. Rack structures have a cross-section in the shape of the letter “C” and are located vertically in the frame. The racks are installed together with guide profiles of the appropriate size. The ends of the products are equipped with two holes through which utility lines are laid (hidden in the walls). They are attached to the guides with self-tapping screws, which are easily centered thanks to the longitudinal grooves.

They have a cross-section in the shape of the letter “P” without curved edges - this allows you to get a tight fit of the racks to the upper and lower elements. They are needed not only for fastening rack parts, but also for installing jumpers between them. During manufacturing, holes are drilled in the structures into which dowels are inserted during installation.

Partitions “Knauf”, specifications which are indicated in the table below, can also consist of arched profiles that serve as the basis curved structures. They are made of different radii, and the shelves can be wrapped inward or outward.

Cladding options

During installation, structures can be sheathed with different types plasterboard sheets. The sheathing is attached to metal profiles and can have 1, 2 or 3 layers. This is necessary when the building is subject to deformation loads.

Conventional plasterboard is used in rooms with normal humidity and differs from other species gray. The composition includes protective additives that make the material “breathable”. When manufactured, it is painted green.

IN fire resistant sheets add special additives that are not subject to combustion. The material is different pink. Combined gypsum plasterboard combines the properties of fire-resistant and moisture-resistant types. It can be recognized by its green coloration with red markings.

Knauf partition installation technology

There is nothing complicated in this process, but it is important to know some rules and nuances. First you need to prepare the walls, floor and ceiling. They will need careful alignment so that the guides fit without distortion. Next stage- applying markings, the evenness of which is checked by a level, cord and plumb line.

After preparing the base, begin installing the profiles:

  1. Install load-bearing elements and attach them with dowels (pitch - 200-400 mm).
  2. Have vertical structures, which are located at equal intervals (corresponding to half the width of the plasterboard).
  3. They are attached with self-tapping screws.
  4. Lay the horizontal guides so that they define two identical planes of the future partition.
  5. The frame is secured using a cross and special screws.

The result should be a frame with square cells 600x600 mm.

Insulation and plasterboard covering

Installation of the Knauf partition also includes laying a soundproofing layer. Most a budget option allows you not to use Additional materials, however, if necessary, you can put foil-based insulation or mineral wool inside the frame.

After installing the frame, laying insulation and engineering communications You can start attaching drywall. For these purposes, special screws are used. You should know that the sheets can be connected arbitrarily, but a checkerboard order is preferable. Thanks to this, there will be no cracks in the structure and a stronger connection will be obtained.

Partitions “Knauf” - designs with original elements, characterized by durability and high quality. Their use will allow you to erect a small building in a short time.

Relatively new technology Knauf was developed and offered by the German company Tigi-Knauf, whose main activity is related to the production of high quality materials for repair and construction work, including plasterboard sheets different types, profiles, fastening elements.

The essence of the technology in the case of ceiling installation comes down to the use of Knauf products with the aim of maximizing the leveling of the ceiling and delicately masking communications with minimal time and labor.

What are the requirements for the frame within the technology

Knauf company focuses on several important nuances, which must be taken into account when assembling a frame for a suspended ceiling using its technology. These include:

  • use of plasterboard sheets produced by the company with high level protection from moisture;
  • installation of profiles to avoid deformation of the ceiling under the influence of weight finishing material performed in a checkerboard pattern with overlap or staggered;
  • Knauf fastening elements are used for connection;
  • to prevent deformation of the coating under the influence of vibrations that occur when the door is regularly opened, avoid joining sheets in the center of the opening;
  • the finished frame must be finished with thermal insulation tape.

With your own hands, a gypsum board ceiling using Knauf technology is assembled from special profiles marked UD and CD.

Advantages of technology: why it is used

Properly planned and installed plasterboard structures can not only complement the interior, but also add the necessary accents, adjust the size of the room, and hide communications and electrical wiring. Ceiling installation using Knauf technology allows you to create practical designer ceilings With minimal costs energy and time. Finished design opens up more opportunities for experimenting with light and demonstrates excellent thermal and sound insulation performance.

Installation of ceilings is carried out from the materials included in the kit. It includes sheets of plasterboard from the manufacturer with optimal sizes and properties, metal frame. Working with such a set is convenient even for a beginner.

Preparation for installation of the structure

Installing a Knauf plasterboard ceiling is permitted only after completion of construction and finishing work associated with wet processes. In addition, by this time the walls should be leveled and finished.

Start device process ceiling structure allowed subject to compliance with temperature and humidity conditions. It is important that the temperature is not lower than 10 degrees Celsius and the humidity does not exceed 60%.

The beginning of the work must necessarily be the correct calculation of the ceiling, drawing up a design project, and carrying out markings. At the same stage, the functionality of ventilation, electrical and other communications is checked.

Using a level for control and a tapping thread, mark a line on the walls around the perimeter of the room. Taking into account the type of drywall chosen for installation, mark the guides with points for mounting the hangers.

Suspensions are secured with anchors or dowels in the marked areas. Further work will depend on the choice of a wooden or metal frame.

So, the technology for installing Knauf plasterboard on the ceiling using wooden frame assumes the following algorithm:

  1. The beam is attached to the base using a direct or quickly mounted suspension. The second option will allow you to instantly change the mounting side.
  2. Fix the guide beam on the ceiling surface using pads to reduce differences in the height of the base.

Some features of installing a metal frame:

  1. The profiles are connected with hangers, not forgetting about the expansion gap of 10 mm (this will protect the structure during temperature changes).
  2. Use sealing tape to lay under the guide profile.
  3. Only a wall profile is used; solid guides are attached along a long wall. The dowel fastening spacing is up to 30 cm, the supporting profile must fit into the guide by at least 3 cm.

The finished frame is covered with sheets plasterboard Knauf, again subject to some nuances.

Finishing gypsum board ceilings - what you need to know

When installing a ceiling using Knauf technology, you must adhere to the main rule: the sheets are fixed across load-bearing profile with self-tapping screws at right angles. Before installation, the sheets must be processed in the area of ​​the edge not covered with cardboard to remove the chamfer.

Installation of sheets is carried out with an assistant or using a special lifting mechanism. The sheets are fastened without joints, as already noted, in a checkerboard pattern or staggered. It is correct that the sheet be laid in the longitudinal direction without a gap, while in the transverse direction a small gap would form. Only in this case will it be possible to putty the joint in such a way as to obtain a perfectly even seam.

It must be taken into account that temperature changes will affect the plasterboard surface of the ceiling - the sheets will expand and slightly deform. To avoid serious deformations, special expansion joints are installed in increments of 15 m.

So that the screws do not spoil finishing coating separated by caps, they are twisted with a slight immersion into the sheet to a depth of no more than 1 mm. The joints are sealed with reinforcing tape.

Finishing - stages of implementation

Designing and installing two-level ceilings in accordance with the described technology, it is recommended to increase the strength of the material through the use of finishing based on water-repellent compounds and putty mixtures.

The seams are masked using the following technology:

  • fill the joints putty mixture, using a narrow spatula, removing residues;
  • attach the seam tape;
  • cover the tape with putty and remove residues from the surface no earlier than after 45 minutes;
  • putty screw heads;
  • putty the seams again, removing the residue, this time with a wide spatula;
  • polish the surface;
  • install an aluminum corner or PVC corner in the area of ​​the outer corners;
  • attach a dividing tape between the gypsum board and internal corner, after which the surface is covered with putty;
  • Paint and plaster the completely dry material.

Drywall is widely used in apartment renovations. It is used to level walls and ceilings, construct niches and boxes, modernize doorways, and perform many decorative elements. Eat certain rules installation of these structures that must be observed. Leading drywall manufacturers have developed entire kits for the convenience of consumers. Knauf technology has gained particular popularity in our country.

Benefits of using technology

Knauf produces a whole line of ready-made kits, varying depending on the type and size of the structure.

The main advantage of Knauf kits: they include everything necessary for installing a wall or partition, from drywall to fasteners. This gives the consumer several advantages, including:

  • Guaranteed to use only quality materials. This is facilitated by a strict proprietary control system designed for minimum tolerances in the manufacture of gypsum boards and other elements.
  • Ease of calculating the consumption of drywall and other parts of the structure. A simple online calculator, available on many websites, is sufficient. You need to enter the dimensions of your wall or partition into it, indicating the number of doors and windows, and it will display full list all necessary elements indicating their quantity.
  • The manufacturer provides each kit with detailed assembly instructions, so even an untrained person can carry it out.
  • By purchasing materials separately, you may forget some details. Using the kit solves this problem.

Installation procedure for Knauf kits

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

  • Guide profiles are attached to the dowels.
  • Vertical posts are installed at selected optimal intervals. It is recommended to fix them using a cutter with a bend.
  • Horizontal jumpers are installed.
  • If necessary, communications are extended and insulation is installed.
  • The gypsum board frame is sheathed with special branded screws.
  • Conduct finishing corners and joints of sheets.

Installation features

The system for assembling walls and partitions using this technology has its own nuances that must be taken into account to achieve an optimal result:

  • To ensure high strength individual elements the frame is strengthened by nesting one profile into another.
  • The guides are attached to dowels at at least three points. The profile plane adjacent to the base is preliminarily covered with damper tape.
  • Often it is necessary to join elements of metal structures that are not long enough. In this case, the connection points should be spaced, for example, placed in a checkerboard pattern. This will reduce the likelihood of vibrations or various deformations of the structure.
  • The 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 using a cutter or branded self-tapping screws. Crab connectors are used at intersections.
  • Sheathing elements made of gypsum plasterboard are attached end-to-end with the necessary gaps to compensate for the thermal expansion of the material. Subsequently, they are filled with a special composition produced by the same Knauf company.
  • When constructing gypsum plasterboard partitions that have window niches or doorways, it is prohibited to join the sheets above them. Otherwise, there is a risk of seams coming apart due to vibrations that occur when using windows and doors. The elements are joined 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 proprietary insulation based on mineral wool. The following kits are available:

  • C 111 - with one layer of cladding. Minimum thickness and instability to loads do not allow such a structure 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 beams for lathing.
  • C 115 is a set with a double frame, lined with two layers of plasterboard. This allows, by increasing the thickness of the partition, to place a double layer of mineral wool in it. In terms of its characteristics, this design is close to an ordinary wall.
  • C 116 - also performed on a double spaced frame. Internal cavities, remaining inside it, allow you to produce hidden installation communications. Moved away from the wall two-layer cladding implemented in kit C 626.
  • C 113 or C 367 - sets with triple skin. Designed for cases where it is necessary to use drywall different types: Moisture resistant, fire resistant and regular in many combinations.
  • C 118 – used for especially strong walls and partitions. In it, sheets of galvanized steel 0.5 mm thick are laid between layers of plasterboard.
  • C 361, C 362, C 363 - sets on a single frame, sheathed in 1, 2 or 3 layers, respectively, with Knauf gypsum-fiber supersheets. From 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 ducts.

Various combinations of frames and skins are possible. All of them are presented in the Knauf product line.

A single frame is used when you do not plan to hang anything heavy on the wall, and also if significant insulation or sound insulation is not required. But to attach it to the wall household appliances, which has considerable weight, you will have to make a double frame with reinforcement.

Features of the formation of corners from plasterboard

The corners play an important role in the construction of a plasterboard structure. 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.

Gypsum plasterboard structures can have both internal and external corners. To form each of them, their own techniques are used. First of all, the frame is assembled.

External corners are made as follows:

  • Two vertical posts forming an edge are installed in the guides so as to form a single angle. It is unacceptable to install them offset: in this case, there will be a void under the joint of the drywall sheets.
  • The racks are fixed in the guides with a pair of screws at each fastening point. Professionals prefer to use a cutter: such a connection does not contain any bulges that interfere with the tight fit of the plasterboard.
  • Fragments plasterboard sheathing 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.

Drywall is used to create arches, various room decor, partitions, recesses in the wall, 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, whose frame consists entirely of metal profile. The design is created using a special technology that eliminates various unforeseen circumstances.

Knauf partitions can be different. They are installed in various rooms, with different sound insulation, for different purposes. Partitions can be of different types and are divided according to certain parameters.

According to their design, partitions are divided into:

  • Partitions with one layer of cladding;
  • Partitions with two layers of cladding;
  • Partitions with three layers of cladding;
  • Partitions with one layer of cladding consisting of super Knauf sheets moisture-resistant on a single-type frame.

In addition to these types, there are partitions with built-in special channels for ventilation and communication. The next parameter by which partitions are divided 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.

Knauf plasterboard partitions: main advantages

Why is drywall and Knauf partitions so popular? Since the 90s, drywall has been almost synonymous with the word European-quality renovation. This material appeared on the Russian market 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:

  • Installation of partitions can be carried out independently without the involvement of specialists; detailed instructions are included in the product;
  • It is very easy to calculate the required amount of material and its cost;
  • Each kit has the required number of parts, it is impossible to forget anything;
  • The kit will provide quick and easy process creating a partition;
  • The Knauf material is very durable, so the partition can withstand even an earthquake.

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 walls. As mentioned above, there are different strengths and sound insulation, depending on the type of room you should choose a suitable kit.

Technology for installing partitions from plasterboard Knauf

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 drywall material Knauf company brought special technology And general recommendations for the installation of partitions.

They look like this:

  1. Each set of partitions has top and bottom rails and posts. These racks can have different widths, which depend on the height of the room where installation is intended, as well as on the weight of the overall structure.
  2. To attach the guides, it is recommended to use dowels; it is necessary to fix at least 3 points.
  3. to install rack profiles, a distance of 600 mm should be maintained; in some cases, the distance can be reduced.
  4. To secure the racks, you should use the “notch-and-bend” method; it is permissible to use special self-tapping screws from Knauf.
  5. To attach the device to a suspended ceiling, it is necessary to comply with the fire resistance class.
  6. Mineral wool can be used for sound insulation.
  7. To install sheets, you should use the “end-to-end” method, i.e. lay them without a gap.

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. The horizontal beam serves as the upper boundary. Following these recommendations will help you make a long-lasting, high-quality design.

High-quality gypsum board partitions using the Knauf system: what will influence the choice of set

Exist Various types partitions that suit different room parameters. On this moment There are about 25 kits for sale for installing partitions using the Knauf system. All sets are marked with the letter "C", which is combined with a specific set number.

To choose matching set for installation, the following factors should be considered:

  • Height of the room or space;
  • Desired noise level;
  • Possible load on the wall in the form of furniture or equipment;
  • Availability of communication systems;
  • Door type or lack thereof;
  • Desired height of the partition;
  • Room temperature and humidity level;
  • Type of room and its purpose (bedroom, kitchen, bathroom, living room).

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.

Modern Knauf technology and drywall: walls and partitions (video)

Plasterboard partitions Knauf - worthy and reliable way to build a wall in the desired location. Simplicity and ease of use, installation will help make the process easy installation and pleasant. 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.

Purpose and content of the technical map

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.

  • This instruction will save the master from studying these very norms and requirements and will speed up the delivery of the work to the customer. If you follow all recommendations, the work will comply with fire and environmental safety standards, GOST, SNiP requirements.
  • The Knauf technological map contains tables with ready-made initial data of the main components of the frame structure for the ceiling.
Ceiling Knauf

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 manual states required material and an algorithm for assembling a frame of one type or another, methods for performing individual design tasks are described.

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.

Types of ceiling structures

The frame for the ceiling is made from both Knauf metal profiles and wooden blocks.


There are 5 types of suspended ceiling designs:

  1. Ceiling P 111 (the technology is known among craftsmen as “system 111”). The biaxial frame is assembled from wooden blocks.
  2. Ceiling P 112. Biaxial frame made of metal profiles.
  3. Ceiling P 113. Uniaxial frame made of Knauf metal profile.
  4. Ceiling P 131. A frame in which a wall profile is used with fastening not to the base of the ceiling, but to the walls.
  5. Architectural and decorative ceiling P 19. Complex multi-level frame.

Frame guides

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.

Metal carcass 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:

  • Guide profile PN. The cross-section has a size of 27×28 mm. There are factory holes in the wall through which installation to the base of the wall is carried out.
  • Complete with the PN, a load-bearing PP profile is installed. In cross section it has a size of 60×27 mm.

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 junctions of rooms, use a reinforced UA profile on the ceiling.

Fasteners

Profile connection work is performed using the following elements:

  1. Multi-level transverse connector for PP profile (60×27). It is sold flat, so it must be bent before installation.
  2. Single-level cross connector "Crab".
  3. One-way cross connector. The upper side clings to the supporting profile.
  4. A rotating multi-level connector that allows you to connect the supporting profile at any angle.
  5. Longitudinal single-level connector. It is used when it is necessary to increase the supporting profile.
  6. Universal connector. Necessary in order to connect the supporting profile in one plane at any angle.

Frame installation work Knauf ceiling performed using the following elements:

  • Straight U-shaped suspension.

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.

  • Anchor suspension with adjustable clamp, quick suspension. They are similar due to the presence of a fastening rod. Its length can reach 1500 mm, which allows you to adjust the required ceiling gap in a wide range. The disadvantage is that the load is limited to 25 kg. This is considered a low figure, since all average calculations in the Knauf technical map are based on a load of 40 kg.

  • Adjustable vernier suspension. It is a telescopic structure made of two parts. Designed for a load of 40 kg.
  • A combined suspension, in which there is both a rod and a retractable element of the vernier suspension.
  • To connect metal elements, you need an LN screw (with a sharp tip) and an LM screw (with a self-tapping tip).
  • Installation of a heavy profile in the P131 system is carried out using FN self-tapping screws.
  • Installation of guides to the wall is carried out with metal or nylon dowels.
  • Installation to hollow structures in a sheet of Knauf plasterboard is performed with multifunctional dowels or butterfly dowels.
  • Installation attachments The sheets are connected using a dowel with a screw thread.
  • Drywall is screwed with TN screws (in a standard profile) or TB (in a thick sheet profile). The MN screw is used for screwing into a gypsum fiber sheet.

Types of drywall

Depending on operating conditions, required drywall Knauf is chosen from the following varieties:

Type A. Regular construction plasterboard. This sheet is used for heated rooms with normal humidity levels (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:

  1. Sheet with straight edge.
  2. Sheet with a cut corner.
  3. Sheet with a thinned edge.
  4. Sheet with a rounded one-sided chamfer.
  5. Sheet with a semicircular edge.

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 the guide beam to the base using a direct or quick-mount suspension. When using a quick suspension, alternately change the side of attachment to the beam.
  • Installation of the guide bar with anchor dowels directly on the ceiling. In this case, in places where there are differences in the base, pads are used.

Installation of a profile frame:

  • The P112 ceiling is mounted in the same way, only in order to connect the guide and supporting profile, two-level suspensions are used. When cutting the guides, an expansion gap of 10 mm is made. It will prevent surface deformation due to temperature changes.
  • Single-axle installation Knauf systems P 113 differs in that the technology involves laying a sealing tape under the guide profile.
  • The work of assembling the P 131 system differs from that described above in that a wall profile is used, and the installation of guides is carried out along the long wall of the room. These structures are usually mounted under a heavy ceiling, so the required spacing for fastening the dowels is no more than 30 cm. Only solid guides are used. The supporting profile must fit into the guide by at least 3 cm.

Fastening drywall sheets

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, a sheet of plasterboard expands, so in large rooms it is necessary to provide expansion joints in 15 m increments.

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.
