Armstrong ceiling (Armstrong) has gained its popularity due to simple installation technology and the ability to easily reach the communications, which are traditionally carried out in the undercarriage.

Especially this property of the ceiling is valued when creating office communications, which must be periodically upgraded, change and simply serve. The design of the ceiling is the plates attached to metallic frame. One-piece plates are interspersed with Armstrong lamps. And those and others can be easily dismantled and removed. How to make the ceiling Armstrong do it yourself?

Preparatory work

The ceiling Armstrong is not difficult to install, which will save on installation work. Before installing, you need to spend all communications, install ventilation channels, Make wiring for lighting. All wiring must be enclosed in the corrugation, protecting cables from short circuit In case of a flood or fire.

Marking

First of all, with the competent installation of the suspended ceiling, Armstrong markups. To do this, it is necessary to determine the lower angle of the room, measure from the ceiling down 10-15 cm (depending on the height of the lamps placed) and with the help of a laser level, output the markup to all angles and walls. You can duplicate a laser pointer to a marker or painting tape.

On the markup you need to attach wall corners 19 \\ 24. A longer side should lay down to the wall. Scissors for metal joint profiles are cut at an angle of 45 degrees.

A chop cord with applied paint needs to be signed diagonally and determine the center of the ceiling. Further on the laser projector, exhibit the size of 120 cm by 60 cm and blacks the grid on the ceiling in accordance with the laser markup. Immediately on the markup you need to apply the place of installation of the lamps.

Installation of suspensions

Every 120 cm from the wall to the wall, the T-shaped suspension will be installed. Between the two profiles, 2 Armstrong plates should be fitted with dimensions 60 by 60.

Profiles should be attached to the suspension to the ceiling.

The step of the suspension depends on the severity of the profile and distances between the walls: on average, the suspensions are attached to the ceiling at a distance of 90 cm -150 cm. Additional suspensions are desirable to install in places where the plates with lamps will be installed.

Assembly of the carcass

For the most part, 90% is the correct and beautiful installation of the suspended ceiling Armstrong depends on the thoroughness and accuracy of the frame assembly. All guide installation work must be checked by the level. When all the suspensions are attached, guide profiles are installed.

Usually profiles already have holes for the suspension on the suspensions. The edges of the profiles must be based on a wounded corner, and the center is adjusted by the height of the suspension.

A connection profile 120 cm is installed between the T-shaped profile through the gaps of 120 cm. The profile is inserted into the grooves on the T-shaped profile, located every 30 cm.

All other spaces fill the connection profile long 60cm. This profile connects the middle of the 120th profile at an angle of 90 degrees, and the result is a grille with cells in 60x60 cm.

Simple technology installation of the ceiling Armstrong allows you to mount it, without even having such practices.

Consider this process in more detail.

Preparation

You will need:

(given below);
consumables: ceiling tiles, suspended spokes, carrier profiles, corner, dowel-nails 6x40 for a corner, anchor-wedge for suspensions;
tools: perforator, painting thread, scissors for metal, laser or hydroelectric, hammer, pliers, pencil and roulette.

Installation Instructions

So, how do you install the ceiling Armstrong? Consider the entire process of step by step:

Step number 1. Ceiling markup

First you need to determine which part of the base ceiling is the lowest. Not all slabs of the overlap are perfectly smoothly, since even the SNiP allows them to deviates from horizontally. To search for the bottom point, the level (hydro or laser) is used. If you use the hydroelectric background, then put the mark on the perimeter of the room at any height convenient for you, especially in the corners - and on the inner, and on the external (if any). Then, using a roulette, we measure the distance from the ceiling to the mark. If you use the laser, then set marks is optional. Immediately measure the distance to the laser line. Where the value is less, there is the lowest point.

After that, we note the location of the carrier corner first at the lowest point, lowering it at least 15 cm from the main ceiling.

Then we measure the distance from this mark to the mark set by the hydroevum, or to the laser line. The resulting value is transferred to the remaining angles.

Then with the help of painting thread, the point is connected to each other.

Step number 2. Ceiling centering

If the ceiling is centered so that the sides are the same trimming, it is necessary to find the center of the room. To do this, follow its parties and note their middle. We connect the opposite middle of the painting thread - the place where they cross on the ceiling and will be the center.

Along the long line will enter the guide profile, the size of 3.7 meters. In parallel, there are other lines with a step of 1.20 m.

Note: If the trimming does not fit into the interior design, then you need to experiment with the displacement of the panels to make it less or more from different sides.

In our example, a room with a size of 4x6 meters and, while putting a guide profile in the room center, the trimming of the wall will turn out 200 mm. If you shift the lines on the half of the tile (300 mm) from the center, then the trimming is already 500 mm. Virtually a whole tile. Therefore, we make offset and move on.

From the short central transverse line on all parallel long lines It is necessary to make labels with a step of maximum 1.20 m - the suspensions for guides will be attached.

If the ceiling is not centered, then the lines are placed in parallel long Wall premises at a distance of 1.20 meters from it, with a step of 1.20 m. From short Wall Rooms for suspensions on all long lines are placing points with a maximum step of 120 cm.

Step # 3. Fixed Western Corners

It is very important that when installing a large edge of the corner always adjoined the wall. For their compounds in the corners, cut the ends for forty-five degrees, or make them jack.

Important! Before you need to pre-finish laying all cables, pipes and ventilation system.

Step No. 4. Installation of suspensions

The suspensions are attached to the ceiling using an anchor-wedge, strictly on previously marked points with a step of no more than 120 cm.

Step number 5. Installing a frame

The main profile L3700 has holes for hooks (they need to simply hang on them) and holes for the locks of the transverse profiles L1200. The main profile from the end, which relies on the corner, the metal scissors should be cut together with the lock in such a way that the hole for the transverse profile lock is at a mark, which is clogged with suspension. Follow this so that the ceiling centering is not killed.

When several main profiles are installed in parallel with each other, they can be fixed with the help of transverse, whose locks are snapped into the guide holes. The step between them is 60 cm. By the same principle in transverse profile insert L600. As a result, you must get a steel crate with 60x60 cm cells.

To align the frame in a horizontal position, you need to tighten or relax the suspensions using a butterfly spring.

Step number 6. Installation of ceiling tiles

Tile is easily dirty, so it needs to be placed in clean hands or in pure gloves. It starts in the framework diagonally, the cell is deployed and placed.

That's all installation of the suspended ceiling Armstrong, instruction which is described in this article. Observing it and you can do all the work with your own hands!

Useful advice

Stove trimming. Very often, when installing the ceiling Armstrong, the plates may be required, since not all the rooms are multiple 60 cm. Those panels that need to be reduced to match the sizes of cells are cut into a painting knife.

Laying the lamp. If the ceiling assumes the placement of the lamps, then you need to install and connect immediately after collecting steel carcass - Before installing the plates. To do this, lay the lamp in the groove, pre-connecting it to the network and setting additional suspensions.

Armstrong suspended ceilings

Suspended ceilings such a design first appeared on russian market At the end of the last century. In those days, they were used mainly in public buildings, which attached the premises of the European appearance. But years have passed, and if earlier, the Armstrong ceiling in apartments and their own homes did not even think, today they can often be seen in residential premises. At the same time, any person who does not even have professional skills may perform the installation of such a design.

History

By revealing history tape 150 years ago, we will see how in the American town of Pittsburgh Pennsylvania, a small workshop processing a plug was formed. The owner of this workshop was Morton Armstrong, which began to first produce flooring and ceiling of cork production.

Now this is a prosperous company with 42 plants in 12 countries of the world and more than 15,000 employees.

The composition of the ceiling plates that are products of this manufacturer, except natural minerals - Perlite, clay and slag wool - in large numbers included secondary raw materials, obtained from processing:

maculatory
mineral soluble wool
old ceiling plates
natural Starch
Important! Ceiling plates, despite the fact that secondary raw materials are used in their production, are an environmentally friendly product.

The products for the suspended ceiling include about 500 items, including:

mineral Fiber Ceilings, Metal, Fiberglass, Tree
suspended systems
bent structures
and much more

According to the functionality of the ceiling Armstrong shared on:

acoustic
moisture-resistant
shockproof
antibacterial
fire resistant

The essence of the suspended structures Armstrong

Installation of ceilings Armstrong includes the installation of a frame of metal guides and laying on it mineral plates.

The frame is fixed to the main overlap with a special suspended systemAnd with its absence - ordinary wire. Mineral plates have a small weight and thickness of only 20 mm. They can be two sizes:

60 × 60 cm
60 × 120 cm

Mostly all the ceilings manufactured by Armstrong have white color. In fact, they can be perforated, with decorative drawing or smooth. Metal forms of fine sheets of steel are also produced, on which a synthetic spraying is applied by a galvanic method.

Benefits

Armstrong - Suspended System

The large popularity of the Armstrong suspended structures is due primarily to their versatility. But besides, they have other advantages:

It is possible to hide all communications that pass under the ceiling - wiring, ventilation and air conditioning systems, Internet connection cables, etc.
Quick access in case of repair to hidden structures, for which it is worth removing one or two plates.
The surface of the suspended ceilings has an attractive look and smooth geometric dimensions.
If necessary, the design can be provided additional insulation and noise insulation, although there are ready-made plates that meet these requirements.
Easy I. fast mounting, excluding any wet and dirty processes in the premises.
Ability to create ceilings of different textures, colors and design.
High maintainability, since all elements have the same shape and sizes. Therefore, you can quickly replace the plates that have come into disrepair, new.
IN suspended structures Modern lamps fit easily, allowing creating different lighting spectra - soft matte, warm yellow or cold white light. And this, in turn, helps to share the room on the functional zones.

Application of suspended ceilings

Armstrong designs are most often used when finishing the ceilings public buildings - Theaters, train stations, sports halls, cinemas and libraries, pools and cafeteris, restaurants and audiences. In medical institutions, suspended structures are used in corridors and toilets, wardrobe and halls. Offices I. business centers Also are no exception. And here the ceilings Armstrong - frequent phenomenon.

Montage of ceilings Armstrong.

The ceiling system is universal and easy to install. Her constructive feature It is that the Armstrong ceiling assembly can be made on any distance from the main overlap. This allows you to hide the designs and communications. different sizes and volumes.

In addition, there are unified plates in which air conditioning elements are already mounted, automatic fire extinguishing, ventilation and lighting. It is only worth inserting such a slab and connect the necessary contacts or communications. The location of the lamps can be changed, for which the plates with integrated equipment are simply rearranged from one place to another.

Important! When choosing a suspended system, you need to consider the weight of the embedded equipment and choose the design that can withstand the given loads.

The suspended system is a profile for the suspended ceiling Armstrong with the size of the shelves 15 and 24 mm. The design itself can be both visible and hidden. Color profiles:

white
metallic
gold

Castles can be solidified or brass with increased strength.

Ceiling plates have the edge of different types:

For the suspended system of 24 mm - plates with smooth edges of Board SQ and Tegular SLT, having a wide ledge on the edge.
For system 15 mm - MicroLook FL plates having a narrow recess.

Installation of the ceiling Armstrong

Installation of the ceiling profile includes the following operations:

marking
wall guide installation
mounting suspension to overlapping
installation of basic and transverse profiles
laying mineral plates
installation of lamps

But before starting the installation, all the planned communications should be laid in advance so that after not to dismantle individual plates.

Marking

First of all, relative to the overlap mark the level on which the new suspended ceiling. This should take into account the size of the hidden structures.

To do this, on the desired height from the floor put on the wall mark. After that, the outlined points must be connected by one closed linelocated strictly horizontally. To do this, use a building level 2-3 meters long or water, or laser.

Installation of the suspension system

Mounting frame for ceiling

Then proceed to the installation of T-shaped guides. They are distinguished by the fact that some of them (long) have slits, and others (short) are protrusions. When they are connected, the profile with a protrusion is plugged into an element with a slot. As a result, cells of 60 × 60 or 60 × 120 cm cells are formed - which depends on the type of mineral plates selected. Long elements are installed on the suspensions, and in between them are consistently inserted short, forming a mesh from cells.

When the lattice is collected, it is necessary to check its horizontality with all the same building level - Water or laser. The horizontal inconsistency is eliminated by adjusting the suspensions by increasing or decreasing the size of the wire loop.

Specialists advise you to start the installation of profiles from the formation of a cell in the center of the room. In this case, if the size of the room is not painted with the size of the plates, it will have to cut through the walls, where it is not very noticeable.

The final stage in the device of the suspended ceiling will be laying mineral plates Armstrong in the formed cells and installation of lamps. Standard lamps have dimensions corresponding to the parameters of the ceiling elements Armstrong. They are equipped with a reflective system and four lamps. daylightthat allows you to sufficiently distribute the light stream.

A few days after the installation of the suspended ceiling, it is necessary to check its horizontality, since under the weight of the profiles, lamps and cassettes, it can slightly change the geometric dimensions.

FEATURES OF MONTAGE

The final stage on laying ceiling plates should be carried out at a room in the room + 15-30 degrees, and only after the end of all construction work, including installation of clean floors.

If you plan to install non-standard lamps or other equipment big weight, it should be attached to individual mounting structures.

If insulation or noise insulation is installed ceiling platesThe number of suspensions should be increased in proportion to the weight of the ceiling with additional details.

Conclusion

Armstrong ceilings produced in different versionssuitable for almost any room. They are all distinguished by high technical and decorative properties. And, despite their differences, the installation of such suspended systems is quite able to any person, since already in their very design, simplicity and ease are laid. The main thing is to comply with the recommendations on their installation and the procedure for work.

Armstrong is able to master even a child. If only enough strength to drill a hole hole and integrity to use the level.

Well, seriously, then below we tried to bring full and most detailed instructions for phased assembly Suspended design.

Also allocated features and important moments Mounting on which many do a large number of Errors. Read and do not make your mistakes.

We give step-by-step instructions for mounting the suspended ceiling Armstrong:

STEP 1

It is necessary to make a complete installation or marking of all engineering communications and networks over your ceiling.

IMPORTANT
Note that the distance from the overlap should not be less than 15 cm

Step 2.

State the horizontal along the entire length of the perimeter of the walls of the room with laser Level, level, hydraulic level, ruler or other tools

IMPORTANT
With a significant (more than 4 m) elevation, the height of the installation of the suspended ceiling will necessarily affect such characteristics of the room as:
convection of heat and air turnover indoors
lighting of the workplace
overall lighting of the room

Consider these characteristics when choosing and designing the height of the suspended ceilings

Step 3.

Set the L-shaped profile lines using a dowel - screws

Step 4.

IMPORTANT
In the absence of a detailed project, it is necessary to correctly define the middle of the ceiling of the room so that it will continue to look most aesthetic (and symmetry should be observed).

Step 5.

The center of the room and will be the starting point for mounting Profile T24.From which 1 is placed parallels with a step of 1200 mm.

Step 6.

From the central point we determined where the 1st suspension on the subsequent parallel lines is mounted, suspensions are mounted for guide profiles with a step of 90 cm. Fastening of suspensions for guides and other profiles to the overlap is carried out with the help of clogged dowels, anchor bolts, expatiable dowels, depending from construction inter-storey overlap or coating.

Step 7.

Configuring all the suspensions, by mounting the guides of the profile L3600 and L1200.

Step 8.

Adjust the level of installation of profiles with the help of special "butterflies" on the suspension.

Step 9.

When installing panels, it is necessary to use protective gloves in order to prevent contact with mineral Vata. components and preservation of aesthetic type of panels. And do not forget to follow the drawing of the panels - do not retreat from the project.

let's say once again briefly about the advantages of the ceilings by type Armstrong:

convenience in repair
ability to choose a number of specified characteristics.
ability to repair almost all engineering communications without a complete dismantling

and yet about some shortcomings:

limitations in the choice of designer and architectural solutions
low average resistance to mechanical damage
mandatory decrease in the height of the room.

Knowing the shortcomings and advantages, having a project on hands, what else did you need ??

Right - step-by-step instruction by installation of the suspended ceiling Armstrong!

It is such an extended package of knowledge and skills that allows you not only to qualitatively control the course of work, but even fulfill them yourself.

Watch the video on how to make the installation of the Armstrong type ceiling

Attractive ceiling is one of the conditions of a good appearance of the room. Therefore, when repairing this issue, a lot of attention is paid. But make the ceiling attractive than the walls are more complex working conditions. If you need quickly, inexpensive to bring this part of the premises in order - your selection of the ceiling Armstrong. This is a fast-mounted suspension system that gives a sea of \u200b\u200bfeatures.

System device

Armstrong suspended ceiling consists of a profile system, with the help of suspensions attached to a rough ceiling. These profiles form square or rectangular cells in which lamps and plates are installed. All this together and is the ceiling system Armstrong.

Armstrong ceiling - one of the options

Profiles are bearing (guides). It is them through the suspensions that are attached to the rough ceiling and carry the main load. The total mass of the entire system is small, therefore, the guides are installed after 120 cm. Along the lines in 50 cm increments, the suspensions are mounted. There are hooks in their lower part, and there are holes in the guides. Guides are simply hung on the hooks. After that, parallel guides were obtained in a step of 120 cm.

Between them with the same step - 120 cm - a transverse profile is installed. As a result, we obtain a cell 120 cm * 120 cm. The plates of the suspended ceiling Armstrong have a size of 60 * 60 cm (if you become accurate, then 598 mm * 598 mm). For their installation, the frameworks are still fixed - to get a cell with the desired size. After that, it remains only to mount the lamps and install the plates in the cells.

Advantages and disadvantages

Armstrong ceilings were originally developed for use in industrial, service and public premises. But a number of excellent qualities led to the fact that they are also used in private homes and apartments. Here is the list of properties of suspended ceilings type Armstrong:

Armstrong ceiling is a really wonderful product. Apparently because he was so loved by the owners of offices, shopping centers, cinemas, etc. But there are also disadvantages. First - appearance Such a ceiling is ideal for office or public space, but in private premises not all perceive them. But it is a matter of taste. The second is the suspension system and "eats" the height of the ceilings with which many and so problems. But if the ceilings are more or less normal, this system can be set. That's all the cons.

Elements of the system

The Armstrong ceiling system consists of a set of elements that are easily connected to each other. One of its advantages is modularity that allows you to get a ceiling of any size and configuration. The problem is only with nonlinear forms - they are not provided and there are no full-time solutions. Because this type of suspended ceiling is used only in square and rectangular rooms.

Profiles

Profiles for the ceiling Armstrong Dealet from Lung aluminum alloy. Perforation is applied on the top of the profiles, with which they are attached to the suspensions and fit together. The lower part of the profiles is the one that is visible from the room - may have a silver color, but more often - white. There are also black and golden, you can find other colors, but they already need to look.

Profiles length 600 mm, 1200 mm, 3600 mm. Beaching profiles must be solid (in case of negotiability, they can fight), because the length we select such that the profile is not shorter than the room. It is cut into the sections of the desired length.

The transverse profiles are dialing partially a length of 120 cm, partly - 60 cm. We will have to consider how much you need to create a suspension system in your case. They will not cut them out - protrusions are made around the edges, with which they are joined with carriers.

Bearing and transverse profiles are two sizes - under different types Plates: with a shelf by 15 mm and 24 mm. There can be different and "back" - under different thickness of the plates (19 mm, 24 mm and 29 mm).

There are still viscent profiles. They are made in the form of a corner, mounted around the perimeter of the room. Extreme plates are based on them. They also have with shelves of different sizes - 19 mm and 24 mm.

Plates

Plates for suspended ceilings Armstrong are two sizes - 120 cm * 60 cm and 60 cm * 60 cm. The second option is more common, perhaps because the squares are better perceived than rectangles. There are also different thicknesses - from 6 mm to 19 mm. The greater the thickness, the greater the degree of soundproofing has such a ceiling, but in many respects this characteristic depends on the material from which the plates are made. And they are several species:

Class economy. The most cheap of all, they have high hygroscopicity and poorly endure increased humidity. Moisture they absorb in the forehead of the form - in the form of a liquid during subtopation of neighbors from above or from the air. Having absorbed moisture, become heavy, they begin to change the form - to fuse that spoils the appearance. In general, the option is cheap, but it feels well in rooms with climate control and constant humidity. This group includes Oasis (Oasis) and, Oasis +, Cortega (Gorta), Tatra (Tatra), Bajkal (Baikal).
Prima class. This is more dear panelsBut they both are much better in characteristics. First, they are more durable, have increased resistance to moisture (85% vs. 65% at the economy class). They are better both in terms of sound insulation and appearance. This group includes the ADRIA collections (Adria), Casa (Casa), Cirrus (Tsirrus), Plain (Plun), Duna + (Dune Plus).
Plates of class prima
Moisture-resistant. This type of plates for the suspended ceiling can be used in wet rooms or high humidity air. There are two types of Mylar (Mular), NewTone Residence (Newton Residence).
Acoustic. Have improved sound-absorption specifications. Suitable for mounting in shopping halls, offices. Produced in two types: Neeva (Niwa), Frequence (Fricenz).
Hygienic. These plates are well clean, designed for medical institutions and food industry enterprises. Type of just one - Bioguard (Bioguard).
Acoustic and hygienic - for specific use
Designer. These plates for ceilings Armstrong are significantly different in appearance from all others. They are used when placing clubs, restaurants, bars. Have a presentable, and sometimes luxurious viewBut there are already a lot. Modifications Several: Visual (Visual), Cellio (Sellieo), Graphis Linear (Grafis Liner), Cirrus Image (Zirrus Image).

The higher it was about the authentic plates that Armstrong produces. There are other types and species produced by other campaigns. The name and appearance may differ, but the division by category is approximately the same.

For example, there are metal plates - white, from a solid sheet and with perforation different size and forms, there are painted in different colors, There are plastic - translucent and with applied photo printing. In general, various plates are embedded in this system.

Another point: Plates on the ceiling Armstrong around the edges have a protrusion. This protrusion is of different widths and depths. Under the dimensions of this protrusion and the type of profile is selected. Maybe the opposite, but they must be shy.

Suspensions and how can they replace them

Armstrong ceilings are in the top hole for installing fasteners, in the bottom - the hook that holds the profile. Top part Fastened to the ceiling with a dowel or other fasteners (depending on the material of the overlap).

Of all this variety, a variant with two studs is most often used (the photo above is the third right and the photo below). These suspensions are inexpensive, quickly collected, allow you to easily adjust the height of the ceiling when the need arises to set it in the same plane.

But these suspensions have minimum height 25 cm. It's a lot even in some offices, and in houses and apartments and suppressed. Exit - to shorten the hairpins (as on top photo Right) or use sweater materials. The most suitable is steel studs with a ring at the end and a piece of elastic steel wire. The minus of this attachment is difficult to adjust the height of the suspension. We will have to make them exactly the length they need.

Also suit a dowel with hooks at the ends. But here you will also need additional hooks from the wire, since too small distance to the ceiling will not allow to put the plates - the space for maneuver is necessary. Minimum distance Between the main and suspended ceiling - 25 mm and it will be very uncomfortable. It is desirable to have at least 50 mm. But this is only if there are no luminaires or fans in the ceiling.

Lamps and ventilation grilles

Full luminaires and ventilation lattices are well suited for offices, trading rates, public I. medical institutions. They have the same size as the plates and are simply installed in the selected place. With the connection of the lamps there is no problem - the extensive undercover space allows you to bring the wireless cross section without problems. They are placed in metal trays fixed on the ceiling or.

In apartments and homes, regular lamps look at at least strange, and power is clearly greater than necessary. In this case, usually use. It is better to take with LEDs - they almost do not heat and consume little electricity, and the lights give enough.

The use of vents in homes and apartments is the case rather exceptional. The system itself is non-negotical, many plates with perforation, which ensures a sufficient degree of ventilation of the undercaption. If, after all, additional holes are needed, you can use a regular lattice or embed smaller, cutting out a suitable hole in the stove.

Installation of the ceiling Armstrong

Collect the ceiling Armstrong simply: you will need a drill, suitable fastener (dowel or self-tapping screw, depending on the floor of the overlap), it is not bad to have a water and bubble. For cutting profiles, it is possible to use scissors for metal, and it is possible - a grinder with a cutting disk or hacksaw with a metal blade.

The technology of mounting the suspended ceiling Armstrong in steps looks like this:

We note on the walls level on which will be located hinged ceiling. It is easier to do it with a level, harder - with a bubble level.
According to the planned line, fastening a wall profile. There are S. profiles multiple width Shelves, when installing do not confuse - the shelf must be the same size as the profiles. Fixed to the walls of suitable fasteners every 50 cm.
Attaching the willed profile measure the required length of the carrier profile and cut off the right amount pieces. At the same time, note that not always the size of the room is obtained by multiple 60 cm. In most cases, it accounts for extreme stoves to cut. There is nothing terrible in this, but it is necessary to properly develop a plan for placing plates on the ceiling - "Subsidence" must be dispersed on both sides. But it is necessary to make it so that the narrow strips are not at the edges (see figure).
On the ceiling, we mark the line of fastening the guide profiles. They are installed after 120 cm, that is, carrier profiles will be less than cells. On these lines every 50 cm set the suspensions.
On the installed suspensions, carrying the supporting profiles sliced \u200b\u200bon the segments of the desired length. In profiles there is perforation. In one of the holes we start the hook and press it - to be kept tight. The edges of the supporting profiles will bring in the already installed wall.
We take a transverse profile with a length of 120 cm, install them inserting protrusions at the edges into cuts on the carrier profile. The result is a grid of rectangular cells 120 * 60 cm.
We take short transverse profiles of 60 cm at 60 cm and insert so that the grid with a cell is 60 * 60 cm. Fastening is the same - the protrusion is started into the neckline.
I exhibit all the suspensions so that the ceiling is in the same plane. Here it can help the level (laser level), but you can do the usual construction.
In the resulting system insert plates. They are deployed sideways, carefully we turn down, then we lower in place. It is necessary to work with clean hands - the plates are dumping. If necessary, they are cut in the usual stationery knife (put on a flat clean surface, apply a ruler or rule along the line of cutting line or rule, spend along the stationery knife, pressing well on it).

Here you have a step-by-step instruction on the installation of Armstrong. Everything is really easy. It is necessary only to pre-think the plane layout plan and understand for yourself, where, at what distance from the walls will be the carrier profile. Then everything is going as a designer.
