The Armstrong ceiling has gained its popularity due to its simple installation technology and the ability, even with the ceiling in use, to easily reach communications that are traditionally located in the ceiling space.
This property of the ceiling is especially appreciated when creating office communications, which need to be periodically upgraded, changed and simply maintained. The ceiling structure consists of slabs fixed to metal frame. Solid slabs are interspersed with Armstrong lamps. Both can be easily dismantled and removed. How to make an Armstrong ceiling with your own hands?
Preparatory work
It is not difficult to install the Armstrong ceiling with your own hands, which will save on installation work Oh. Before starting installation, you need to carry out all communications, install ventilation ducts, make wiring for lighting. All wiring must be enclosed in corrugated pipes that protect the cables from short circuits in the event of a flood or fire.
Marking
First of all, when proper installation Armstrong suspended ceiling is marked. To do this, you need to determine the lower corner of the room, measure 10-15 cm from the ceiling down (depending on the height of the placed lamps) and using laser level display markings on all corners and walls. Duplicate laser pointer You can use a marker or masking tape.
According to the markings, you need to attach 19\24 wall corners. The longer side should be adjacent to the wall. Using metal scissors, the joints of the profiles are cut at an angle of 45 degrees.
Using a chop cord with applied paint, you need to mark the diagonals and determine the center of the ceiling. Next, we set the dimensions of 120 cm by 60 cm on the laser projector and draw a grid on the ceiling in accordance with the laser markings. Immediately on the marking you need to mark the installation locations of the lamps.
Installation of hangers
A T-shaped suspension will be installed every 120 cm from wall to wall. Between the two profiles, 2 Armstrong slabs measuring 60 by 60 should fit.
The profiles must be mounted on hangers to the ceiling.
The pitch of the suspensions depends on the weight of the profile and the distance between the walls: on average, the suspensions are attached to the ceiling at a distance of 90 cm -150 cm. It is advisable to install additional suspensions in places where slabs with lamps will be installed.
Frame assembly
For the most part, 90% of the correct and beautiful installation of an Armstrong suspended ceiling depends on the thoroughness and accuracy of assembling the frame. All work on installation of guides must be checked with a level. When all the hangers are attached, the guide profiles are installed.
Typically, profiles already have holes for hanging on hangers. The edges of the profiles should rest on the wall corner, and the center should be adjusted by the height of the suspension.
Installed between the T-profile connection profile 120 cm at intervals of 120 cm. The profile is inserted into the grooves on the T-shaped profile, located every 30 cm.
All other gaps are filled with a 60cm long connecting profile. This profile connects the middle of the 120th profile at an angle of 90 degrees, and the result is a lattice with cells of 60x60 cm.

Armstrong ceiling installation procedure
Installation of an Armstrong suspended ceiling can be divided into several main stages:
I. Installation of wall corner (corner profile)
Corner profile ceiling system Armstrong is installed on the walls along the perimeter of the room in a horizontal plane. The horizontal marking line is usually set using a hydraulic level or laser level. Direct fastening to the walls is carried out using expansion dowels, anchors or self-tapping screws with a pitch of no more than 0.5 m.
II. Installation of supporting guides and spring suspensions
Bearing rails with a length of 3.6 m or 3.7 m are installed in increments of 1.2 m parallel to one of the walls or at a certain angle relative to the walls with a diagonal design of the ceiling being mounted. If the supporting rails are not long enough, they are easily connected to each other using the available special locks.
Simultaneously with the installation of the supporting rails, spring hangers are installed. The suspension rod with an eye is attached to the ceiling using expansion dowels, anchors or self-tapping screws, the suspension rod with a hook is attached through a special hole to the supporting rail. The spring clamp of the suspension allows you to adjust the distance between the ceiling and the suspension system, securely fixing both rods together. Spring hangers are installed at a distance of no more than 1.2 m from each other and no more than 0.6 m from the wall.
III. Installation of frame cross slats
Transverse slats of 1.2 m are installed perpendicular to the load-bearing slats of 3.6 m with a step of 0.6 m from one of the walls and between each other.
Transverse slats 0.6 m are installed perpendicular to slats 1.2 m, i.e. parallel to the supporting rails 3.6 m with a step of 1.2 m from each other.
IV. Installation of raster lamps
If the Armstrong suspended ceiling involves the placement of 600x600mm raster lamps, then we proceed to this stage immediately after installing the 0.6m slats, i.e. after finishing assembling the ceiling sheathing. We remember that a suspended ceiling is not load-bearing structure, therefore, recessed lamps are installed on additional suspensions.
Suspended ceiling Armstrong has recently become very popular and is widely used in finishing office premises, supermarkets, pharmacies, various public and cultural buildings. The only place where it is not used is residential premises. One of the reasons is that until recently the composition of suspended ceiling slabs included asbestos, which is a carcinogenic material. Otherwise, these ceilings have a number of positive properties.
What is an Armstrong suspended ceiling?
The Armstrong suspended ceiling is easy and quick to install, which has great importance with the huge areas of modern supermarkets. Armstrong consists of:
- Light frame;
- Suspension system made of wire or special strings;
- Clamping tabs that are attached to reinforced concrete slabs ceilings using dowels;
- Modular slabs, the size of which is usually 600x600 mm.
The most labor-intensive operation when installing an Armstrong suspended ceiling with your own hands is the installation of a frame consisting of a wall profile and a main frame made of a T-shaped profile, having a length of 3.7 m; 1.2 m; 0.6 m. The slabs that are placed inside the frame cells can be varied - from any material, in various colors, with different acoustic characteristics. When installing such ceilings, luminaires measuring 600x600 mm are used - raster, matching in size with the ceiling tiles and having fluorescent lamps, and can also be Spotlights of various types.
Advantages and disadvantages of Armstrong ceiling
The widespread use of Armstrong-type suspended ceilings indicates the presence positive qualities:
- The design of the suspended ceiling is lightweight, which makes it possible to use these ceilings over large areas without any problems;
- All structural elements made of non-flammable materials;
- Armstrong slabs have soundproofing characteristics, which allows them to be used in rooms associated with sound reproduction;
- With its help you can hide all communications located on the ceiling;
- It is quickly installed and has a low cost.
Like everyone else building structures, in addition to the positive qualities, there are also disadvantages. The main disadvantage of such ceilings is their very poor resistance to moisture in any form - if water gets in, the slabs become unusable.
Types of slabs for suspended ceilings
According to the installation method, there are two types of ceiling tiles:
- Classic type, which are inserted into the frame from the inside;
- Modern slabs that snap into place when installed outside.
Snap-on ceiling tiles
By appearance, quality and special characteristics, plates for Armstrong are divided into:
- Economy series - have normal characteristics and a fairly reasonable price, are not installed in places with high humidity;
- Prima series is a higher class, characterized by increased moisture resistance, the presence of six types of surface, and has greater durability;
- Acoustic series - special slabs with increased sound insulation characteristics;
- Hygienic series – characterized by increased antibacterial properties. They are used when installed in medical institutions;
- Moisture-resistant series - boards intended for use in rooms with a high degree of humidity.
Necessary tool
To perform high-quality work when installing an Armstrong ceiling on your own, you must purchase the following tool:
- Tape measure, black marker;
- Laser or water level;
- Hacksaw for metal;
- Painting knife with a set of spare blades;
- Chop cord;
- Rotary hammer with a set of drills 6, 8, 10 mm;
- Screwdriver;
- Metal scissors;
- Bricklayer's level;
- Extension cord for connecting power tools;
- Square;
- Hammer.
Calculation of suspended ceiling
When ordering a suspended ceiling, you only need to know the area in square meters. Based on this value, it is possible to calculate required amount components of the frame and suspensions. There is a calculator to determine all the necessary components.
Design « Armstrong »
The suspended ceiling includes a frame, suspension system and slabs. The frame consists of:
- Bearing profile T24 or T15, length 3.6 m;
- Cross profile T24 or T15, 1.2 m long and 0.6 m long;
- Corner wall profile 19/24.
The frame is attached to the ceiling using a suspension system, which consists of:
- A string with an eye at one end;
- A string with a hook at one end;
- Butterfly springs with 4 holes.

Preparatory stage
Before the beginning self-installation Armstrong suspended ceiling, all work on laying communications must be completed - electrical cables, ventilation ducts, etc. Do-it-yourself installation of an Armstrong suspended ceiling begins with detailed marking of the ceiling. The surface of the future ceiling must be strictly horizontal. This can be easily checked using a laser level, which shows a horizontal line along all four walls. Our task is to determine the depth of the false ceiling, i.e. the distance from the floor slabs to the planned ceiling level. In this case, the height of the laid communications is taken into account and 100-120 mm is added. Using a tape measure, we transfer the marks in the corners of the room from the laser mark to the level of our ceiling and make marks with a marker. Then, using a tapping cord, we mark the lines. We smear the cord with graphite, apply it to the marks in the corners and beat off lines along all the walls. As a result, we have the level of our ceiling and are ready to proceed to the next stage.
Frame installation
Along the perimeter of the room, using the drawn line, we proceed to install an L-shaped profile with a section size of 24x19 mm. Depending on the material of the walls, dowels with a diameter of 6-8 mm are used for this purpose. The corner or, as experts call it, the starting profile is attached to the wall with dowels and screws every 500 mm. It must be remembered that the painted side of the profile should be facing down. At the corners of the rooms, the profile is cut at an angle of 45 degrees with a hacksaw.
The next step: we need to determine the center of our room. To do this, we connect two opposite corners in pairs and mark the point of intersection. From the center across the room, 1.2 m are laid out in each direction - this is the step of the supporting profile of section T24 or T15. The supporting profiles are fixed to the ceiling using hangers. The length of the supporting profiles is 3.6 m; if necessary, they can be connected using special locks.
The suspension consists of two strings, at the end of one there is a loop for a screw, at the end of the second there is a hook. The strings are connected using a 4-hole butterfly. After attaching the supporting profiles, after 1.2 m we begin to attach transverse profiles T24 or T15 with a length of 1.2 m and 0.6 m - they are inserted into special slots in the supporting profiles. In this case, there should be formed frame construction in the form of cells with a cell of 600x600 mm.
Scheme of fastening frame profiles Important! All dowels for attaching hangers must be installed very firmly so that sagging does not occur during operation due to the dowels being pulled out.
The plane of the frame is checked with a level and adjusted using hangers.
Installation of ceiling slabs
The installation of an Armstrong suspended ceiling is completed by installing the ceiling tiles into the finished frame. After two or three days, the horizontal surface is checked and, if necessary, corrections are made.
Types of ceiling lamps
There are several types of lamps used in Armstrong suspended ceilings.
– lamps specially produced for ceilings of this type, 600x600 mm in size. They can be staggered instead of ceiling tiles. The only requirement: additional hangers are installed on the slatted frame in the places where the lamps are installed. Such lamps are equipped with fluorescent lamps.
also available in sizes 600x600 mm or 1200x600 mm and equipped with LED lamps.
– can be used in suspended ceilings; holes are made for them in the center of the ceiling slabs.

Conclusion
Armstrong type suspended ceiling has big amount positive qualities, which allows it to be successfully used when repair time and budget are limited. This ceiling can be easily repaired - installation is quite simple and does not require the involvement of highly qualified specialists.
Tiled ceiling Armstrong is the most popular among suspension systems. It is appreciated both in offices and in private apartments for its many advantages, but it also has disadvantages. Next, all the intricacies of installing an Armstrong ceiling will be discussed and tips and recommendations for using this coating will be given.
System Features
The exact name of this type of coating is a tile-cellular suspended ceiling. In our country, it is traditionally called Armstrong after the American manufacturing company. It was this company that more than 150 years ago began to produce, among many others, building materials natural fiber boards. Similar slabs are now used to install Armstrong-type ceilings. Although the design and installation technology of such suspension systems have changed somewhat, the name remains as a common noun.
Armstrong tile-cellular ceiling coverings are frame systems made of metal profiles, suspensions, which are attached to concrete base and mineral slabs, which are directly covered. The material for them is obtained from mineral wool with the addition of polymers, starch, latex and cellulose. The color of the slabs is predominantly white, but decorative coverings may have other colors. Frame parts are made of light metals: aluminum and stainless steel.
The weight of one mineral slab can be from 1 to 3 kg, the load per 1 sq. m. it turns out from 2.7 to 8 kg. Products have mainly White color, they are quite fragile, susceptible to moisture and high temperatures, so they are stored in reliable moisture-proof packaging. Such slabs are cut with a regular paint knife. There are also more durable options made from latex and plastic; these require a harder tool for processing.
Advantages ceiling coverings Armstrong types are as follows:
- lightness of the entire structure and ease of installation;
- the ability to hide all unevenness and defects of the ceiling;
- safety and environmental friendliness of the material;
- the ability to easily replace slabs with defects;
- good noise protection.
After installation, suspended ceilings form voids in which electrical cables and other communications are usually hidden. If repairs or installation of new wiring are required, then it is easy to get to it by removing several plates, then they are simply put in place.
Ceilings of this type have their disadvantages:
- since they are installed at some distance from the ceiling, they take away the height from the room, too much low rooms It is not recommended to install the Armstrong system;
- mineral slabs are quite fragile, they are afraid of water, so it is better not to install them in rooms with high humidity;
- Armstrong ceilings are sensitive to temperature changes.
Usually, based on these disadvantages, certain places are chosen where Armstrong ceilings are installed. The leaders here are offices, institutions, corridors in various buildings. But often apartment owners make similar coverings when renovating, most often in the hallways. In rooms where there may be high humidity, for example, in kitchens, the problem is also easily solved - put special types Armstrong coatings: hygienic with protection from steam, grease adhesion and functional, moisture resistant.
How to calculate the amount of materials?
To calculate the amount of materials for installing Armstrong suspended ceilings, you generally need to know what parts they are assembled from.
For installation you need standard products with dimensions:
- mineral slab - dimensions 600x600 mm - this is the European standard, there is also an American version 610x610 mm, but it is practically not found here;
- corner profiles for walls – length 3 m;
- main guides – length 3.7 m;
- cross guides 1.2 m;
- cross guides 0.6 m;
- height-adjustable hangers for attaching to the ceiling.
Based on the area (S) and perimeter (P), the number necessary elements calculated using the formulas:
- mineral plate – 2.78xS;
- corner profiles for walls – P/3;
- main guides – 0.23xS;
- transverse guides – 1.4xS;
- number of hangers – 0.7xS.
In these calculations, the number of whole parts is rounded up. But you need to understand that only with a visual picture can you imagine how it is actually more convenient and beautiful to cut slabs and profiles in a room. So, for example, for 1 m2 you need approximately 2.78 pieces of standard Armstrong slabs, rounded up. But it is clear that in practice they will be trimmed with maximum economy in order to use as little trimming as possible. Therefore, it is best to calculate the material standards using a drawing with the lattice of the future frame.
Additional items
As additional elements Armstrong ceiling frames are equipped with fastening units on which they are fixed to concrete floor pendants. For them, you can use a regular screw with a dowel or a collet. Another additional component is lamps. For such a design, they can be standard, with dimensions of 600x600 mm and simply inserted into the frame instead of a regular plate. Quantity lighting fixtures and the frequency of their insertion depends on the design and desired level of lighting in the room.
Additional components for Armstrong ceilings can be decorative plates with patterns or squares with round cutouts in the middle for recessed spotlights.
Preparatory work
Next item technological map Installing Armstrong ceilings means preparing the surface. This type of finishing visually hides all defects of the old ceiling, but it is not protected from mechanical damage. Therefore, first of all, it is necessary to remove the old coating - plaster or whitewash, which can peel off and fall onto the mineral slabs. If existing material If it sticks tightly to the ceiling, you don’t have to remove it.
If ceiling leaks, you need to waterproof it, since Armstrong ceiling slabs are afraid of moisture. Even if they are functional and moisture-resistant, this will not save the future ceiling from major leaks. As waterproofing material You can use bitumen, waterproof polymer plaster or latex mastic. The first option is cheaper, the last two, although more expensive, are more effective and harmless to living space. Existing seams, cracks and crevices must be sealed with alabaster or gypsum putty.
Armstrong ceiling construction technology allows the frame to be placed at a distance of 15-25 cm from the floor slab. This means that thermal insulation can be placed in the free space. For this purpose, various insulating materials are used: polystyrene foam, mineral wool, expanded polystyrene. They can be attached to the old ceiling using an adhesive base, screws, or use a rigid frame metal profile, wooden slats. Also at this stage the necessary electrical wiring is laid.
The following Armstrong installation instructions include markings. A line is drawn along the walls along which the corner profiles of the perimeter of the future structure will be attached. Marking can be done using a laser or regular level from the lowest corner in the room. The mounting locations for Euro-suspensions are marked on the ceiling. It would also be useful to draw all the lines along which the transverse and longitudinal guides will go. After this, you can begin installation.
Installation
It is very easy to install the Armstrong system with your own hands, 10-15 sq. m of covering can be installed in 1 day.
For assembly you will need the following tools:
- laser or bubble level;
- roulette;
- drill or hammer drill with concrete drill;
- Phillips screwdriver or screwdriver;
- metal scissors or grinder for cutting profiles;
- screws or anchor bolts.
The good thing about the elements of such ceilings is that they are universal; the parts from any company are identical and are made up of guides and adjustable suspensions with the same fastenings. All profiles, except for the corner ones for walls, do not require self-tapping screws or self-tapping screws; they are connected using their own fastening system. Therefore, to install them, you do not need extra tools and materials.
Installation begins with securing the corner guides around the perimeter. They need to be fastened with the shelves down so that the top edge runs exactly along the previously marked line. Self-tapping screws with dowels or anchor bolts are used, pitch 50 cm. In the corners, where the profiles join, they are cut off a little and bent.
Then in old ceiling you need to screw in the fastening units and hang all the metal hangers on them by the upper hinges. The layout of the fasteners must be such that maximum distance between them did not exceed 1.2 m, and from any wall - 0.6 m. In places where heavier elements are placed: lamps, fans, split systems, additional suspensions must be fixed, at some offset from the location of the future device.
Then you need to assemble the main guides, which are attached to the hooks of the suspensions in special holes and hung on the shelves of corner profiles around the perimeter. If the length of one guide is not enough for the room, then you can build it up from two identical ones. The lock at the end of the rail is used as a connector. After collecting all the profiles, they are adjusted horizontally using a butterfly clamp on each hanger.
Next you need to assemble the longitudinal and transverse slats. They all have standard fasteners that fit into slots on the side of the guides. After complete installation of the frame, its horizontal level is checked again for reliability.
Before installing mineral slabs, you must first install lamps and other built-in elements. This makes it easier to pull through the free cells necessary wires and ventilation hoses. When all electrical devices in place and connected, then proceed to fixing the slabs themselves.
Blind mineral slabs are inserted diagonally into the cell, lifting and turning, you need to carefully lay them on the profiles. You should not put too much pressure on them from below; they should fit effortlessly.
During subsequent repairs, installation of new lamps, fans, laying cables or decorative panels, the laid slabs are simply easily removed from the cells, and after the work is also placed in their place.
It's worth remembering that different variants finishing materials can be used for various institutions. For entertainment venues, schools, clubs, and cinemas, it is worth choosing Armstrong acoustic ceilings with increased sound insulation. And for canteens, cafes and restaurants, hygienic plates are specially made from a material that is resistant to grease stains and steam. Moisture-resistant elements containing latex are installed in swimming pools, bathhouses, and laundries.
A separate type of Armstrong ceilings are decorative slabs. They usually don't have any useful properties. physical properties, as described above, but perform an aesthetic function. Some of them are a great option design art. There are mineral slabs with a three-dimensional pattern embossed on the surface, with different textures, reflecting light, glossy or matte, to match the texture different breeds wood So you can use your imagination when renovating.
Today you can find it very often. These suspension systems very popular thanks to modern style. Installation of the Armstrong suspended ceiling is very simple and allows you to hide any ceiling communications.
Regular suspended ceiling Armstrong specifications has simply impressive:
- Noise reduction up to 39 dB
- Light reflection over 92%
- The ceiling deflection is only 2 mm at a temperature of +32 degrees and a humidity of 90%
In addition, the materials from which the ceiling plates are made are environmentally friendly and do not contain formaldehyde and asbestos.
In a room that has already been renovated. Compared to plasterboard ceilings, Armstrong does not require additional finishing (putty, painting, wallpaper).
Any type of lighting fixture can be built into them. The structure is attached to the floor slabs, but due to its low weight it does not place any serious load on them.
If you decide to use for finishing an apartment or country house Armstrong-type suspended ceiling, then this is a great option. It will give the room a modern, stylish look.
The ease of assembly of the structure will not take much of your time, and will also allow you to avoid dust in the room. Almost any self-respecting home craftsman can do Armstrong with his own hands.
Calculation of the ceiling system kit
To know how to calculate an Armstrong suspended ceiling, you need to draw a floor plan (top view) and indicate on it the exact dimensions of each wall. To do this, use a measuring tape. To calculate the ceiling, you need to know what is included in its delivery.
Armstrong components are listed below:
- Decorative ceiling tiles 600 mm x 600 mm x 15 mm
- Wall corner (PU profile 19 x 24)
- Profile load-bearing type T 15 x 38 or T 24 x 38
- Cross profile type T 15 or T 24
- Universal suspension (spoke, spring)
- The number of wall corners is equal to the perimeter of the room. It is attached to the wall with dowel nails 6 x 40 mm in increments of 35-45 cm.
- The supporting profile for the Armstrong suspended ceiling is attached on hangers to the existing one along long wall. The distance between the profiles is calculated in such a way that the decorative plate measuring 600 x 600 mm fits on the shelves of two adjacent profiles.
- When to install the ceiling hanging Armstrong, the hangers are placed in 1 m increments along the line of the supporting profiles. The lines must be drawn on the room plan and the points for attaching the suspensions must be indicated.
- The supporting profiles and the wall corner are connected to each other by jumpers. They are fastened in increments of 600 mm.
It is important to know! Supporting profiles must be placed symmetrically relative to the longitudinal axis of the room.
These four simple rules, will help you easily calculate the number of elements for a suspended ceiling system. The calculation of Armstrong suspended ceilings is completed and you can proceed to the next operation.
How to assemble a suspended ceiling: marking the walls and ceiling
It is important to know! The minimum height to which the ceiling can be lowered is equal to the height of the recessed lamp plus 1 cm (this is the technological gap).
Using a laser or water level, determine the horizontal plane of the assembled ceiling. To do this, make marks along the perimeter and connect them with masking plaster tape. The operation requires the presence of one assistant.
After marking the walls, mark the axes of the supporting profiles. To simplify the work, at a distance of 30 cm or 60 cm from the longest wall of the room (depending on how the axes are shown in the drawing), pull the cord parallel to the wall. The edges of the cord are tied to dowels driven into the walls. This is the first axis.
The second axis is tensioned perpendicular to the first, departing from the corner at a distance according to the drawing. The remaining supporting profiles are marked from the axes. On lines with a step of 1 m mark the installation points of universal hangers.
Installation of suspended frame
The galvanized wall corner is cut to size. The ends of the profile that meet at the corners are cut with metal scissors at an angle of 45 degrees. Holes are drilled in the corner in increments of 30-40 cm.
The corner profile is applied to the wall along the marking line and marks for the holes are made with a pencil. The holes are drilled with a drill and a concrete drill bit (or depending on the material from which the walls are made). After the holes are ready, dowels are driven into them with a hammer. The wall corner profile is secured to the wall with self-tapping screws.
According to the marks on the axes of the supporting profiles, 6 x 40 mm dowels are used to fasten the hangers. A hole is prepared using a drill and a concrete drill. A dowel is driven into it with a hammer. A self-tapping screw is screwed through the loop at one end of the suspension with a screwdriver. If dowel-nails are used, then the nail is hammered into the dowel.
The Armstrong suspended ceiling is attached to the hangers using a hook in the notch in the profile. The end of the profile should lie on the shelf of the wall corner. In order to increase the length of the profiles, they are joined together.
To do this, you can use ready-made joints or homemade plates cut from scraps of the same profile. The profile is cut to size using a grinder or a hacksaw. The profile height is adjusted with a universal suspension. A spring is installed to fix the position of the suspension spokes. It is quite rigid and can withstand high tensile forces. This will ensure reliable fastening of the structure to the floor slabs.
A transverse profile is used for the construction of jumpers and structural rigidity. The supporting profile has grooves for the joint, and the cross profile has hooks. The hook and cutout (notch) form a reliable lock when connected.
Important to remember! There should be an angle of 90 degrees between the supporting and transverse profiles. Check this condition with a construction corner.
At the wall, the hook of the transverse profile can be cut off so that it fits on the shelf of the wall corner. After assembling all the frame elements, you can proceed to installing the lighting wiring.
Installation of lamps
Before starting work, make sure that all electrical communications (wires) do not have exposed ends and are laid in protective corrugated pipes.
This precaution will prevent possible damage electric shock and the occurrence of wiring short circuits. Perform the wiring electrical wires to the locations of lighting devices. At the connection points of the lamps, the corrugation is cut, and the wire is pulled out in a loop.
Raster fluorescent lamps are often used. Their size of 600 x 600 mm allows them to fit precisely on the shelves of the load-bearing and cross profiles. In addition, daylight is wonderfully diffused throughout the entire room thanks to large mirror reflectors. For lighting, you can use recessed spotlights. To do this, carefully cut a hole in the decorative ceiling panel equal to the diameter of the lighting fixture.
Spotlights for Armstrong suspended ceilings have mounting springs. They are pressed out and the device is installed in the hole, after which they are smoothly released. Springs press the lamp to the panel.
Installation of ceiling panels
When the lighting fixtures are installed and connected, the cells suspended ceiling fill out decorative panels. If necessary, they are cut to size using a pencil, ruler and construction or stationery knife. If metal panels are used, they are trimmed with a grinder.
The installation of the suspended ceiling is complete. A video on installing suspended ceilings will help you visually familiarize yourself with the process
