The plasterboard ceiling is curved. The elegance and beauty of curved ceilings. Video

What makes an interior design original? Fine Decoration Materials? Furniture of non-standard shapes? Original combination colors? Probably not only, because you can also make a special ceiling. For this you can build special design– curved plasterboard ceiling. You can implement this yourself. And if there is a problem with the choice of forms, you can focus on existing ones, widely presented with photos and videos on the Internet.

It should also be noted that such designs also allow you to hide communications, as well as obtain original lighting in the room.

Marking

Curved ceiling - at least two levels with a certain difference in height relative to each other.

Therefore, the markings will have to be applied twice: once on the ceiling, and a second time on the sheets of the first level. Certain tools are used for this.

The wave can be applied by hand, without the use of special tools, because its shape may be irregular. And minor defects will still be eliminated with putty.

Since it is more convenient to make markings on the floor rather than on the ceiling, it is worth using a template. The material can be drywall, and the tool can be a steel meter or compass.

You can also use the point method. To do this, a certain amount of them is applied, which is then connected by a smooth line.

A curved structure can be created from parts of different circles, for which you can use a compass. You can make it yourself using a profile, a self-tapping screw and a pencil.

After applying the drawing, installation can begin.

Drop

As a rule, the difference between the waves is about 15 cm. The minimum distance is 10 mm. But even such a small difference may be enough for volume. Which is sometimes, especially in small spaces, very important.

Installation

If you need to make a relief, you can attach only a sheet of drywall cut to the desired shape.

The first level is performed according to standard rules. At the point where the wave passes, the profile is mounted more frequently, which also applies to the use of hangers. It is more convenient to do this if a pattern has already been applied to the ceiling.

Then plasterboard sheets are fixed. They need to be made longer than the wave line. At the same time, it is also necessary to use self-tapping screws more often so that the reliability of the structure is at its best.

When the first level of the curved ceiling is ready, a line is drawn on the drywall for the new level. Next, the bent profile is attached. To get it, you need to make cuts on the inside. Self-tapping screws are used for fastening. When installing the second level, you should not forget about the thickness of the sheets in order to correctly calculate the distances. But you also need to leave an extra few centimeters for a better fit in place.

How to sew vertical surfaces? For this purpose, sheets of plasterboard are used. For curved ceilings, it is better to take arched sheets with a thickness of 6.5 mm.

Using drywall, you can make waves with curves and several meters long. The sheets must be thoroughly moistened with water, wait several hours, after which installation can be carried out without using cuts.

Finally, all that remains is to putty the ceiling. This can be polymer or gypsum putty. When it dries, the residues must be removed, the surface cleaned, primed and puttied again, if necessary. And then you can glue wallpaper or immediately paint the surface.

Curved ceiling is simple, but requires experience

Installation may require a long period of time if you have no previous experience installing such curved structures. Therefore, you need to be patient, and everything will work out on your own. And the result will amaze with its originality, quality and beauty.

In the old days, people lived in ordinary apartments and simple houses and did not think about what simple room You can make a wonderful home for relaxation and living. With the advent of drywall on the market, people's fantasies and ideas began to appear. Every day more and more nuances are being revealed, why you can make curved plasterboard ceilings at home.

Design and design of a curved plasterboard ceiling When working with plasterboard, it is necessary, firstly, to observe safety measures, and secondly, to adhere to the rule of “precision”.

Drywall is a flexible material for installation. It is so easy to use that anyone can use it to turn a fairy tale into reality. With this material you can:

Create smooth transitions and lines.
The room is divided into an area for relaxation and work.
On the ceiling, do something reminiscent of a fairy tale.
Hide all the unevenness and imperfections in the house.
Bring your wildest ideas to life.
Create an unusual light range.
Create sound effects (using material bends).

Example of a multi-level curved ceiling

Anywhere in the house, with the help of plasterboard, real beauty is created on the ceiling, which will amaze the guests with their individuality.

Rules and subtleties of surface marking

A curved plasterboard ceiling is always a minimum. They are located at a certain height from each other. The marking is done in stages. Tools you will need for marking:

Important! When markings are applied, all curves are necessarily connected by straight lines.

Stages of marking

Initially, markings are applied to the ceiling for the first level. Points for hanging are marked. They will be installed at a distance of 60 cm from each other, the profiles will be installed at a distance of 40 cm from each other, this is also marked on the ceiling.
Markings from the ceiling are applied to sheets of drywall.

Roundness and other shapes from drywall are made in the following ways:

The transition between levels can be at least 10 cm, if the vertical transition is made larger, for example, for, it is worth measuring and calculating the height of the room so that afterwards there is no feeling of a “falling ceiling” on your head.

Installation technologies

When installing a curved ceiling, sometimes certain difficulties arise with plasterboard. The material needs to be given the desired shape. This can be done in 2 ways. Templates according to which the sheet will be folded are required in advance.

Wet technology

This technology requires a needle roller and water. On inside sheet, using a roller, indentations are made.

Then the sheet needs to be soaked in water and placed on the pattern template. After some time, the material will take the shape of the original blank. To produce overly curved shapes, it is not advisable to use a sheet larger than 60 cm. The radius of the curved line is directly dependent on the thickness of the sheet. With a size of 9 mm. the minimum radius will be 50 cm, with a thickness of 12 mm. - 1 meter.

Wet drywall must dry well to maintain its intended shape. In order to become more familiar with wet technology, you need to watch a video that shows the creation of the form step by step.

Dry bending

With dry technology it is possible to produce curved lines small sizes. If reinforced sheet is used, a mold template will not be needed. Such sheets are very dense and bend perfectly. The thickness of this sheet is 6.5 mm. When dry bending there are the following details:

Frame production

Design Features:

The video shows the design features of a curved ceiling.

Fastening drywall

The stage of attaching ready-made forms of curved drywall (GKL) is simple in comparison with the manufacture of a frame. But it also has its own subtleties. To ensure that the seams on the ceiling do not subsequently come apart, precise manufacturing of sheet forms is required. The boundaries of the form must exactly coincide with the attached frame and curved profile.

To accurately cut a curved line, you need to mark the points on the sheet using a meter. After this, either connect these points by hand, or use a template to cut out the shape along the drawn lines.

It is best to use a knife designed for this purpose. When the cardboard is cut, the plaster breaks easily. If you have a complex shape in mind for the ceiling, then it will be easier to make a pattern and use it to cut the shape from the sheet. When covering the frame, the cut out shapes are fastened with self-tapping screws at a distance of 25-30 mm from each other.

A curved plasterboard ceiling that is assembled and ready for finishing. The cap of the self-tapping screw must be “sinked” into the sheet so that it is not higher than the surface of the form. To cover the frame with large sheets, the help of a second person is required. If it is not there, you need supports.

Important! In order to do round hole for a lighting fixture, you need to take a crown the right size and an electric drill.

Some features of the frame

When covering a frame with curved lines, there are some features:

Final stage

After completing the sheathing of the frame, you need to proceed. This is done to achieve ideal surface and finishing treatments.

Interesting! Next year 2018, fashionable tones will be considered not only bright and rich tones, but also pastel shades of the rainbow, which smooth transition go from dark to light colors. The border between the transition is practically invisible. In order to do this, you will need a regular sponge. The technique of such a transition of tones is called “Ombre”. In the photo you can see the range of colors flowing smoothly.

From the author: welcome to our construction portal, dear reader. It's no secret that modern renovation rarely involves plastering the ceiling along beacons. This is a labor-intensive process, which, by the way, does not always give an ideal result. Let's just say that this is not even yesterday, but the day before yesterday. Other technologies have replaced it, for example, stretch ceiling and suspended structures. In particular, curved plasterboard ceilings. This will be discussed in this article.

Indeed, when compared with plastering the ceiling using beacons, suspended ceilings are much easier to install, aesthetically attractive and functional: you can recreate the illusion of a floating slab, resort to the use of spotlights to conditionally divide one room into several zones, in addition, from plasterboard You can cut out various shapes.

Here everything is limited only by your fantasy, imagination and ingenuity. Try yourself as a designer of your apartments! Moreover, the installation of curved plasterboard ceilings can be done with your own hands. You will learn the basics of this work from this article.

Features of curved suspended structures

Of course, you can resort to using strict geometric shapes. The material cuts well, and it is easy to give a plasterboard sheet any shape that can be depicted using straight lines. For example, it could be a star shape. But today we are talking directly about curved structures.

For some premises, for example, an office space called open space, a curved plasterboard ceiling may be the only feasible solution. This is an excellent alternative to the banal Armstrong suspension system, which we can see everywhere.

Although, it is worth noting that the solution we are considering cannot be called budget option, but still, let’s note some of its advantages:

first of all - original appearance. You are your own designer, so you can figure out what shape the ceiling will be. Only you decide which decorative elements It’s worth establishing what details to focus on, where to place spotlights and main lighting, and so on. Agree, the Armstrong suspension system does not provide as many opportunities as a curved ceiling;
secondly, quick access to communications. Unless, of course, you use the Loft style in interior design, then communications must be properly hidden. Yes, so that if necessary you have access to them. Curvilinear plasterboard ceilings give us such an excellent opportunity. Yes, Armstrong, of course, also provides us with this opportunity, but, again, we need original, non-standard and “tasty” solutions;
Thirdly, - Fire safety. GKL ( plasterboard sheet) is a fairly fire-resistant material that can protect communications in the event of a fire. The Armstrong ceiling certainly does not give us such an opportunity.

Curvilinear or rounded ceiling can be mounted in shopping centers and other commercial places. It looks quite impressive and stylish.

For your house or apartment, curved suspended structure may also be the only right decision. It is thanks to this type of ceiling that your room can undergo enormous changes. And what does it have to do with better side. I can’t be happier with the fact that you can create all kinds of forms from plasterboard cast simply at the venue installation work. In this case, you do not need a large set of specific tools.

I believe we have already said enough about the merits, originality and versatility of the design we are considering. Now it's time to prepare the tools for work. We will need:

clamp profile. As you probably already understood from the name, this is a tool for working with metal profiles. It is a kind of tongs, more precisely, pincers, with which metal profiles are fastened together;
cutter. This tool is needed to make holes in sheets of drywall. The cutter will become your first assistant when laying communications;
rasp. This tool will be needed to bring the plasterboard to the desired size or to align the edge;
needle roller. It will be required if you decide to install the ceiling using the “wet” method. We'll talk about what it is a little later;
mounting support. Simply put, a lever with a lock. This will help keep the gypsum board in the position you want while the mounting adhesive hardens;
drill/perforator;
screwdriver;
screws/dowels;
hammer;
cardboard cutting knife with a stackable blade;
scotch.

I believe there is no need to comment on the last six items on the list. These tools should always be at hand for anyone who believes that they are worthy of the proud title of “Builder.” Now it's time to talk directly about editing.

Installation of curved plasterboard ceilings

As we have already mentioned in passing, there are “dry” and “wet” technologies for installing gypsum boards. Now we will find out how these two technologies differ and determine which of these technologies is appropriate in a particular case. Let's get started.

“Wet” technology for bending gypsum boards

The use of technology is based on the plasticity of gypsum plasterboard in the wet state. I think you understand what we are talking about. The sheet is given the specific shape we need while it is wet and flexible. Subsequently, it dries, hardens and retains its shape. For these purposes, use gypsum board sheets no more than 0.6 m wide.

In turn, the bend radius of the gypsum board will directly depend on its thickness. For example, if the sheet thickness is 9 mm, then the bending radius will be 50 cm, and if the sheet thickness is 12.5 mm, the radius will be 100 cm.

If you have chosen the “wet” bending technology, the sequence of your actions should be as follows:

place the plasterboard blank on a flat, hard surface;
saturate the gypsum board workpiece with water;
perforate one of its sides (inner/foldable);
wrap around the pre-prepared template with this blank;
secure it with tape and then leave to dry.

That's all - the form is ready for installation on the ceiling! By the way, to make the work go faster, especially if you are not working alone, make several templates for bending the workpieces. Well, if the bending radii differ, then in any case you will need more than one template. Now let's talk about “dry technology”.

“Dry” technology for bending gypsum boards

Using this technology, it is possible to create bends with small radii. In this case, the joints are fixed using special U-shaped metal plates on the back side. They bend according to a pattern. But if you use drywall that is reinforced with fiberglass, you can do without any templates.

For the “dry” method, reinforced gypsum plasterboard is best suited. It costs more than usual, but bends much better. Its thickness does not exceed 0.65 cm. Sometimes it may be necessary to pair two reinforced sheets.

We don't need a needle roller - we need a router to make cuts on the sheet of drywall in the places where it is necessary. After completing the installation work, the side on which you made the cuts must be primed and puttied. Now it is necessary to say a few words about the ceiling frame.

Working with the frame

As a rule, the frame is made from PP 60/27 profile. To obtain a bend, you need to make cuts on the profile and bend it within the required radius. The curved profile must be fixed to the rough ceiling using straight hangers. It may happen that the length of the suspension is not enough; then it needs to be extended with a special hairpin.

In turn, the transverse profiles are mounted on the ceiling in increments of approximately 30–40 cm. The guideline in this case is the curvature of the bend. During the work you need to use two-level connectors.

Initially, it is necessary to hem the sheets of the first level. They should not go beyond the curved line. After the appropriate markings have been made on the first level, the already prepared profile should be secured using self-tapping screws. In this case, the step should be 15–20 cm.

Now you need to set the workpiece in the desired position and fix it with a spacer stand. Then you can start fixing the workpiece with self-tapping screws. You should move from the middle to the edge.

Now you can (and even need) to seal the seams - prime/putty the surface. Now we just have to do the finishing work, but finishing the ceiling is related to the main topic of our article today only indirectly.

We know that it is better to see once than to read a hundred times, so watch the video that demonstrates the process of installing drywall on the ceiling.

Good luck and creative inspiration! Until next time.

A real decoration of the ceiling surface can be a figured structure made of plasterboard, tension cloth or a combination of these two materials. The figured ceiling has its own characteristics and advantages. In addition, there are certain types of figured plasterboard ceilings. We will tell you about the installation sequence of this ceiling covering.

Features and advantages of figured ceilings

Curved plasterboard ceilings are multi-level structures with curved details that follow geometric figures and objects. The texture and colors of the levels are usually different. Multi-level stretch ceilings are also classified as figured structures, because the tiers also differ in color and surface texture.

Such coatings are popular due to their many advantages, including the following:

The main advantage is the aesthetic appeal of the coating.
A figured plasterboard ceiling visually expands the space of the room. If you choose the right color and texture of the coating, the room will appear taller. However, in any case, it is not recommended to install them in a room less than three meters high.
The levels of the ceiling structure divide the room into separate functional areas.
Suspended covering made of any materials hides defects in the base, engineering Communication and building structures.
Possibility of installing mounted, built-in and hidden lighting.
Subject to compliance with installation technology and making the right choice materials, ceiling structures will last for many years.
Behind the ceiling surface you can install thermal insulation material and increase the sound insulation of the room, as well as reduce heat loss.

The disadvantages of such ceiling structures include installation difficulties and high costs for purchasing materials. The main disadvantage of such ceilings is the reduction in the height of the room. The entire covering drops by 10-20 cm, which is low room V apartment building a significant minus.

Important! The weight of the entire structure is significant, so it will significantly weigh down the ceiling. This must be taken into account when installing a ceiling to a dilapidated wooden floor.

Varieties of figured gypsum plasterboard coverings

There are the following types of figured ceilings:

Levels with rectangular or square configuration usually located in the central part of the room. This is the highest tier of the ceiling. Along the perimeter of the room there is a lower level, which, like a frame, encircles the room. IN large rooms such structures can be divided into several squares or rectangles. Most often, built-in lamps are mounted in the lower tier around the perimeter. Sometimes hidden lighting is installed in the box.
Oval and semicircular configuration levels are used in bedrooms, children's rooms and living rooms. Usually the figured part is located above the sleeping area, seating area or dining area.
There are many variations of curved and wavy coatings. They can border the room or divide it into separate functional areas.
Surfaces that repeat the shape of certain objects (butterflies, flowers) or geometric shapes, perform exclusively decorative functions or serve as a basis for lighting sources ( LED strips, chandeliers and spotlights).

Marking the ceiling for a figured structure

Installation of a figured plasterboard ceiling begins with preparation base surface and its markings. The main ceiling does not require special preparation. The old coating, which holds well, does not need to be dismantled. If there are gaps or cracks in the ceiling, they are sealed with repair mortar. Areas with mold are treated with antiseptic compounds.

After this, the room is marked. To do this, draw a diagram of the future coating on paper:

First, draw a floor plan based on measurements. The schematic plan is divided into cells with dimensions of 60x60 cm on a scale. This is the step of installing the metal frame profiles.
Using a colored pencil, draw the boundaries of the curly coating. You can use the corners of the room on the plan or its center as reference points. To get a wavy line, draw several conjugate circles.
Place dots on the markings in increments of 20-40 cm. In these places, hangers will be attached to the ceiling.
Mark installation locations lighting fixtures and wiring routings.

Now we transfer the diagram to the base ceiling. To do this, we draw our covering with chalk on the floor of the room. Next, the location lines of each level are drawn on the walls of the room. To do this, use water or laser level. The minimum distance between the top tier and the ceiling is 40-100 mm. Optimal height level difference – 50 mm.

To mark, measure the height of all corners in the room and select the lowest. From it set aside the height to which each level descends. Using a level, we transfer the marks to the remaining corners. We connect all the marks with lines on the walls. On the ceiling surface we mark the installation locations of the suspensions.

We draw a level difference boundary on the ceiling. To do this, we use reference points (corners or center of the room). We apply markings under the frame. The middle of the profile should run along this line.

Advice! To apply markings, make a large compass. To do this, screw a screw into the ceiling in the center of the intended circle. Tie a thread with a pencil at the end to it. With this compass you can draw large circles.

Installation of supporting frame

To assemble the frame you will need a ceiling, guide and arch profile. The first of them is the main structural element; all the sheathing lintels are assembled from it. The guide profile is attached to the walls and serves as the basis for fixing the ceiling slats. An arched profile is needed to create curved surfaces. Instead of an arched rail, you can use a ceiling profile with notched shelves.

In addition to profiles, to assemble the frame you will need screws with dowels, U-shaped hangers, self-tapping screws, connectors and “crabs”. The following tools are also needed for work:

Bulgarian;
construction level;
roulette;
screwdriver;
ladder;
hammer drill

The frame is assembled in the following order:

According to the markings on the walls of the room, we drill holes in increments of 50 cm and insert dowels into them. We do the same with markings for suspensions on the ceiling.
We attach guide profiles to the horizontal lines on the walls. We connect all the elements using a corner connector.
We attach U-shaped hangers to the ceiling and bend their edges.
We cut the ceiling profiles to the required length and insert them into the guide rails on the walls. In the middle part of the slats we attach them to the ceiling suspensions using short self-tapping screws.
We install jumpers on each side of the longitudinal profiles. We attach them to the main rail with a “crab” connector.
We cut one ceiling profile into short sections to form racks at the point of level difference. They are attached to the frame of the upper tier using a multi-level connector.
Now we make the border of the lower tier. To make a curved border, we make cuts on the profile flanges with equal spacing. Bend the element to get the desired shape. We attach the curved product using connectors to the vertical posts.
Next, between the curved profile of the lower level and the guide on the wall, we install longitudinal ceiling slats. They can be attached to hangers that are fixed to the upper level frame.
We mount the jumpers on the sheathing of the lower tier.

Important! When installing combined ceilings or some types of gypsum plasterboard coverings, the frame is made only for the lower tier. The upper level is a tension panel or a smooth plastered surface.

Fastening drywall

Before installation of gypsum boards begins, power supply networks are laid under the ceiling, bases for lamps and other utilities are installed. Then they begin to cover the frame with plasterboard.

The easiest way is to mount the sheets on horizontal planes. To do this, the sheet is pressed against the frame with clamps and screwed with self-tapping screws. The edge sheets are cut to the required width or in accordance with the configuration of the level boundary. We screw the fasteners along the edge of the sheet at its location above the profile in increments of 15-20 cm.

Important! Don’t forget to make holes for spotlights in advance.

It is somewhat more difficult to make curved planes from plasterboard. To bend a sheet, you can use one of two methods:

On the back side of the material, make cuts to 1/3 of the sheet thickness. They are performed in equal steps. After this, the product can be bent in a given direction.
They go over the inside of the gypsum boards with a spiked roller to make holes in the cardboard. Then the surface is moistened with water and the material is waited for to become wet. The sheet can then be bent and attached to the frame.

After installing all the slabs, the joints between the sheets and the places where the fasteners are installed are puttied. The seams are additionally reinforced with serpyanka. If the ceiling is to be painted, the entire surface is puttied. Then the coating is primed, and after it dries, proceed to finishing wallpaper or painting.

Homeowners are increasingly less likely to resort to the labor-intensive process of leveling surfaces when making repairs. And not because the walls and ceilings in our home have become smoother. There is simply a cleaner and simpler way - to cover them with dry plaster, or drywall, as it is now called. And you will get it perfect flat surface, which can be decorated in any way you like - whitewash, paint, wallpaper or tile.

The designers found this boring, and they began to create unusual volumetric structures indoors. This could be a niche, decorative partition, arch or wave on a plasterboard ceiling.

Ceilings, in particular, are given Special attention. The main feature here is the incorrect geometry of the structure. Human imagination is simply inexhaustible, so no two identical curved ceilings can be found.

Surely you will ask the question: “How can you smoothly bend a hard and brittle sheet?” We will try to answer this and many other questions in as much detail as possible.

Design features

With the introduction of new technologies in the production of curved forms, create a design required configuration It's getting easier. A short instruction will help you, if desired, make a curved one yourself.

In addition to being very beautiful, this form of ceiling also has practical advantages. Intermittent surfaces muffle sounds and create light compositions. You can, on the contrary, amplify the sound and make it directional by arranging the concave surfaces in a certain order.
Designers use this technique when creating ceilings in concert and theater halls. Proper illumination of the design lines makes an unforgettable impression and makes the ceiling simply fabulous, as in the photo below.

Installation of plasterboard ceilings, curved, and even simple geometric shapes, is sometimes the only the right decision For office premises large area with a lot of equipment and utilities.
They can be easily hidden and still be accessible. Due to the natural fire resistance of gypsum, in the event of a fire, the fire will not spread across the ceiling, and communications will not be damaged.

To help the employee

What’s especially nice is that you can create such complex shapes directly at the installation site, using only a small set of tools.

To fasten a metal profile using the cutting and bending method, you will need a tool called a cutter. The connection is made without the use of screws, and is used in combination with guide profiles. They are used during installation.

To make a hole in the gypsum board for wiring, use feather drills 20 mm, while larger ones already require crown attachments of the required diameter.

An edge planer (rasp) is simply necessary for finishing the sheet to the desired size or alignment. The steel body of the plane has a cutting blade resembling a kitchen grater.

Installation of curved plasterboard ceilings, or rather, creation figured surfaces wet method, impossible without a needle roller. With its help, the gypsum board sheet is perforated, which allows it to be well saturated with water and bent to the desired radius. To better understand how this is done, it is worth watching the video.

You will also need a mounting support, which is a lever with a lock. Craftsmen rarely work with it, but the device is very convenient.

Device (handle) for carrying sheet material makes this process very easy and can be used in pairs.
Well, where would we be without a hammer drill, a screwdriver, a utility knife, measuring tools, a hammer cord and a laser or water level - any builder always has them at hand.

Installation features

Bending sheets to obtain an element of any complexity is done in the same way, only the frame designs differ significantly. Before you start bending the gypsum board, you must first make a template from the same drywall and metal profile.

Its main parts are cut out according to markings with a slightly smaller radius than needed for a curved surface.

There are two technologies for making bent forms from plasterboard: dry and wet. Each of these technologies allows for different bending radii. The price of such work directly depends on its labor intensity and complexity of installation.

Wet technology

IN wet technology The natural plasticity of gypsum in a wet state is used. The moistened leaf is given required form, which persists upon subsequent drying.

For the manufacture of curved forms, it is recommended to use sheets with a width of no more than 60 cm. Naturally, the minimum possible bending radius directly depends on the thickness of the plasterboard, for example: with a thickness of 9 mm R = 50 cm, with a thickness of 12.5 mm R = 100 cm.
For large volumes, when a team of several people is working, it is advisable to make a couple of templates, even if the bending radius is the same. And if there are several radii, then there should be the same number of templates.

The plasterboard blank is placed on a flat surface and the back side is thoroughly treated with a needle roller.

Afterwards it is soaked in water. While the sheet is not dry, it is carefully laid on the template and very carefully and smoothly bent, fixing the edges with clamps through the rail.

The part is left to dry, after which it takes the desired shape.

Advice! By the way, if you use fiberglass-reinforced gypsum board, you can completely abandon the templates, because such a sheet bends very well without additional tricks. Reinforced plasterboard is stronger and thinner, only 0.65 cm thick. It is more expensive than conventional plasterboard, but bends well using the dry method. Some designs may require the use of double sheets.

Dry bending

Using dry technology, small radius bends are created:

When dry bending a sheet, you do not need a needle roller, but manual frezer. Along the length of the sheet, on the side that will be convex, cuts are made at the necessary intervals.
Unlike the previous option, the sheet is immediately ready for installation, but to hide its angularity you will have to try during puttying.
Only when all the ceiling parts are made do they begin to install them on the frame.

Some features of the frame

Frame for suspended ceilings assembled from profiles PP 60/27 and PPN 27/28. To obtain a curved surface, the profile notched on the sides is bent to the required radius.

Curved PPN profiles (cut on one side and with the base) are attached to the floor slab using anchor wedges according to the intended markings. From them, sections of the PP profile are lowered down, with a length equal to the height of the box. The same bent PPNs are screwed onto them from below, but now they must have both sides cut through.
We install a guide profile near the wall, level. Now we can fill the frame with load-bearing parts to which the drywall will be screwed. The pitch of the profiles must be a multiple of the sheet size.
All sheet joints must necessarily fall on the profiles.
First, the sheets of the first ceiling level are hemmed, then the rest.

You should be careful when working with bent parts, especially milled ones, as they can tear under their own weight, so an extra pair of hands won’t hurt in this matter.

The seams are sealed as usual; if necessary, the entire surface is puttied. And now, the wave of plasterboard on the ceiling is already pleasing to the eye.

Only Finishing work, and this is a completely different story. A little patience - and now you are admiring the beautiful design of your home, regardless of whether you made this beauty with your own hands or turned to the help of specialists.
