Armstrong ceiling - technical characteristics and properties

Armstrong ceiling: technical characteristics

According to established tradition, the name of the company that was the first to import products to Russia becomes a household name for all products with similar characteristics. In this article we will talk about Armstrong , which unite many manufacturers from Europe, Asia and America.

Classic Armstrong ceiling with built-in lights

The technical characteristics of the Armstrong ceiling imply the installation of mineral fiber boards (modules) in a suspension system created in the subceiling space from:

1. metal profiles;
2. wire hangers.

And the founder of this method of decorating ceilings was the company Armstrong , which proposed a technology that subsequently became extremely popular. Following her, other companies from around the world began producing these products.

Today, the Russian building materials market offers many varieties of this type of suspension systems, which for the convenience of consumers are called the same:

1. Armstrong ceilings;
2. Armstrong type ceiling systems.

Armstrong

The Armstrong company is one of the leaders in the global suspended ceilings market. Founded by Thomas Morton Armstrong almost a century and a half ago, a small balsa wood workshop in Pittsburgh (Pennsylvania, USA) has now grown into a powerful corporation. The concern includes 42 factories located in 12 countries. The company's products appeared in Russia more than 10 years ago, and now they are widely used in repair and construction work in St. Petersburg.

Armstrong suspended ceilings are

• unique operational and technical characteristics;
• compliance with international quality standards;
• environmentally friendly materials;
• full set;
• affordable prices.

Types of Armstrong suspended ceilings

Armstrong ceilings are widely used in the renovation of office premises. They provide good sound insulation, are easy to install, allow you to set the required level of lighting and disguise utility lines.

Economy class ceilings

The technical characteristics of such ceilings include: high impact resistance, moisture resistance, good acoustics and durability. They are the optimal solution for relatively clean rooms, for example, the halls of shopping and entertainment complexes, offices. Armstrong's economy-class ceilings are represented by the BAJKAL, TATRA, CORTEGA, OASIS, RETAIL series. You can find out how much the set costs from the price list.

Types and shapes of ceilings

Armstrong was the first to use various materials for the manufacture of modules . The composition of the Armstrong ceiling structure can be anything, depending on the wishes of the customers.

Most often the composition includes:

1. mineral fiber;
2. polycarbonate;
3. basalt fiber;
4. steel;
5. tree;
6. aluminum and others.

The texture of the Armstrong ceiling system is also varied, and can be:

1. with embossing;
2. with perforation;
3. united by a common geometric pattern;
4. with the addition of decorative elements.

Perforated Armstrong ceiling modules in white and black colors

Such a wide range and rich color range provide unique opportunities for creating exclusive interiors and unique ceilings.

The size of the Armstrong ceiling system can also be any:

1. from 1.5 m2 (the size is ideal for the corridor and utility room);
2. and up to 1000 m2 (the size is ideal for trading floors, waiting areas at the airport or train station).

Armstrong system in a shopping center

Using this ceiling decoration system you can create:

1. smooth surfaces;
2. three-dimensional designs;
3. color panels;
4. multi-level compositions

in residential or public premises, in office and industrial facilities. These can be structures with hidden or visible suspension system, as well as with built-in ventilation ducts, lighting fixtures, sound and video equipment , etc.

Modules

The basis of Armstrong ceiling systems are mineral fiber boards called modules.

They are available in two sizes:

1. 600x600mm (squares);
2. 600x1200mm (rectangles).

Armstrong ceiling drawing with 600x600mm modules

For reference: The thickness of the slabs varies from 8 to 25 mm , and the weight of 1 m2 of ceiling is in the range of 2.5-8.0 kg/m2 , respectively. This variation is explained by the use of different materials - the use of wooden or metal modules makes the structure heavier, while modules made of mineral and basalt fibers, on the contrary, lighten it.

Modules are also usually distinguished by the shape of their edges.

Today there are 3 types on the Russian market:

1. Board – modules with smooth edges, designed for mounting on mounting strips (flush);
2. Tegular – modules with a wide step for a 24 mm ;
3. MicroLook – modules with a narrow step for suspended systems with a width of 15 mm.

Technical characteristics of Armstrong ceilings with different shapes of module edges

Hanging system

To ensure that the modules are securely fastened above the head, a suspension system is designed to be mounted in the subceiling space.

It is made from metal elements and includes:

1. Supporting profile;
2. Cross profile;
3. Corner profile;
4. Adjustable wire hangers.

Connecting profiles into a single structure using technical slots

For reference: The profiles on the front side are covered with a polymer coating, the color of which can be matched to the overall style of decorating the room. The most common is white matte color.

What are the dimensions of the wall profile for plasterboard?

The following products are used to level the walls:

1. Bearing CW – 50x50, 75x50, 100x50, 125x50 and 150x50 mm.
2. UW guide – 50x40, 75x40, 100x40, 125x40 and 150x40 mm.
3. The length of the rack profile is from 2.6 m to 4 meters. The guide is produced 3 - 4 meters. There are differences in appearance: some have 2 strips for fastening, while others have an H-shaped cutout for cables.

In wall construction, a rack type of PS is used, also known as a wall type - common in the creation of plasterboard surfaces.

It has slightly curved sides, and along the “back” there are 2 longitudinal channels.

Manufacturers make strips of such length that it is possible to make calculations and work without waste. The dimensions are:

• length 2.5-4 meters;
• width 6 cm - this is convenient when installing 2 sheets of plasterboard. 3 cm on 1 sheet and the same on the other. The joint is strong;
• the height of the side parts is 27 mm.

A guide strip used in creating a frame on a wall under plasterboard. This is the basis of the entire structure. The product is mounted on the floor and ceiling, a rack guide is inserted into it, fixed with dowel nails, the rack rails are secured into the guides with self-tapping screws, and a direct suspension goes from the wall to the profile.

Guide marking PN, European UW. It has a straight shape without bending. Product length – 3 meters, width 2.7 cm, side height 2.8 cm. Product thickness 0.5 mm.

Auxiliary profiles used for a rigid base under gypsum boards.

1. Corner - used when finishing the structure. This is to protect the corners from impacts.
2. Beacon products - used for plastering surfaces.

In addition to metal strips, to create a frame base for drywall, the following elements are used:

• Direct suspension is a perforated strip. It is folded on the sides, and the center is attached to the wall. A rack profile is fixed to this suspension; it can also be used in a metal frame on the ceiling.
• Connectors. These metal products are mounted when it is necessary to connect 2 profiles. Designed for rack-mount and ceiling profiles.
• Crabs are mounted in a ceiling structure, but if they create a complex vertical frame for a figured plasterboard structure, or reinforce the sheathing to hang heavy objects on the wall, then a crab (connector) is used.

To attach metal strips and direct hangers to the rough base, dowel nails are used.

When choosing metal products to create a frame base for gypsum boards, you need to pay attention to the manufacturer, its quality, how thick the metal is, whether there are traces of corrosion, and the evenness of the product.

Material calculation

Having decided to design the ceiling space using the Armstrong system, you should determine the amount of consumables.

And for this you will need to mark the Armstrong ceiling structure, since in such a visual way it will be immediately visible:

1. Drawing of the future ceiling;
2. Places for attaching profiles.

Wire fastening of profiles to the ceiling

a horizontal line is marked on the walls along which the load-bearing profile , and then a series of parallel straight lines , serving as guidelines for attaching the transverse profiles.

The profiles themselves have technological slots and grooves that allow them to be connected into a single structure. And the height of the system is determined by the presence of lamps and an air duct system, which should also be taken into account when applying markings.

In addition, with the help of markings it will be easy to calculate the required number of hangers . Manufacturers recommend fixing them in increments of no more than 450 mm. The shape of the fasteners often has a hook or eye that makes it easy to attach the hanger.

Is it possible to adjust the sizes

Factories produce standard product lengths of 3-4 meters. However, in creating an even partition or wall with figured elements, different lengths of the product are needed. To do this, the metal elements are either extended or cut to the length required for the structure.

Profile cutting methods:

Which is better: heated floors or radiators?

Warm floorBatteries

1. Scissors for cutting metal. You can cut the product evenly only along the marked lines. The disadvantage is the slightly curved edges after cutting. The cut strip is placed on a flat surface and leveled by tapping with a hammer.
2. A hacksaw is not a very convenient method. There are small shavings from cutting the product. However, the cut will be smooth.
3. Bulgarian. When working with an electrical appliance, sparks fly in all directions.

1. Cutting machine. A large electrical appliance used in large rooms with large volumes of work.

You can cut the profile without any problems using Soviet-made scissors.

Elongation of a metal element. In order to increase the product, 2 methods are used:

1. The use of an extension cord is a durable metal part coated with a protective layer against corrosion. It is applied to the edges of two planks and fixed with self-tapping screws.
2. Homemade extension cord from the PN guide. It is necessary to cut 10 cm from the product and attach it to the edges of the profiles. Fixation is done with self-tapping screws.

It is easy to adjust the length of the metal frame element. You just need to make accurate measurements and marks. You should not lose sight of millimeters, as they can play an important role in the evenness of the structure.

Profiles for creating a frame structure on the wall have certain dimensions and material thickness. They are coated with an anti-corrosion agent (galvanized) - moisture does not affect metal products. Before purchasing profiles, you need to know their number from the measured dimensions of the room.

Advantages of Armstrong suspended ceiling

This type of ceiling has the highest quality standards, which is confirmed by the certificate for the Armstrong ceiling structure issued to customers by the installer. Both the modules and the suspended elements of the load-bearing frame meet all the requirements of environmentalists.

Certificate of conformity for Russian-made Armstrong ceilings

The current GOST R 53298-2009 characterizes the requirements for suspended ceiling structures.

And according to SNiP standards 01.21.97, Armstrong-type suspended ceilings belong to low-hazard structures, and their use is permitted in premises of any purpose, where:

1. temperature regime not lower than + 12 degrees Celsius;
2. air humidity does not exceed 70%

GOST for drywall profile sizes and types

Galvanized rolled steel used in the manufacture of building profiles for frames for plasterboard meets the requirements established by GOST 14918-80 and GOST R 52246-2004. The steel profile for plasterboard is packaged in packs 2 to 4 meters long according to the diagram shown in the figure. The weight of the packaging details is 25 kg. ) A - profile that meets the requirements described in the “Quality” section; ) B - profile with defects that do not lead to a significant change in the geometric shape, dimensions and zinc coating; ) B - substandard profile and metal waste to be used as an ornamental material for non-responsible purposes at the discretion of the customer. The beam is installed on top and bottom of the profile block, in at least 3 places along the length of the profile. It is allowed: to change the quantity and location of the timber, provided that the required strength of fastening the profile in the blocks is achieved and the safety of the profile is ensured during storage and transportation; use a board instead of timber. The mechanical properties of galvanized tape used for the manufacture of profiles for plasterboard meet the requirements established in GOST 14918-80 and GOST R 52246-2004.

Sound absorption

Sound absorption is the ability of suspended ceiling tiles to muffle and focus sound in a room by absorbing some of the energy of sound vibrations - this is especially true in very noisy rooms, such as open-plan offices and call centers.

To create a space with high-quality acoustics, first of all, you need to select suspended slabs that have high sound-absorbing ability.

It is worth adding that maximum sound absorption is also necessary where the source of the main noise is located in the same room, if the task is to reduce the noise level, “lock” it in a certain place.

Armstrong ceilings have a sound absorption coefficient ranging from 0.10 to 1.00 alpha w. For cinemas, concert halls and recording studios, the sound absorption rate should be close to unity. In any case, the suspended ceiling will be called acoustic (or sound-absorbing), starting from 0.40 alpha w and above.

For rooms with high sound absorption requirements, it is better to choose Rockfon Lilia, Dune Supreme slabs from the mid-price segment, or more expensive solutions: Optima or Ultima OP.

Partition profiles

They are marked with the symbols UW (guide), CW (bearing or rack). Compared to flat profiles, these elements have greater width and height.

Their main size range is as follows:

• Bearing CW -50/50 mm, 75/50 mm, 100/50 mm, 125/50 mm, 150/50 mm;
• Guide UW – 50/40 mm, 75/40 mm, 100/40 mm, 125/40 mm, 150/40.

Variations in the length of the supporting rack profile are 2.6 - 4.0 meters. The standard guide length is 4000 mm. In terms of cross-sectional shape, partition profiles differ markedly from planar ones. Two longitudinal ribs are rolled onto them, increasing the rigidity of the wall, and an H-shaped cutout is made in the rack to allow cable lines to pass through.

Partition (guide) UW profile

CW profile for partitions (rack-mount)

UW plasterboard guide profiles are used to define the mounting plane of the wall and install load-bearing profiles. They are mounted along the entire perimeter of the partition (on the walls, floor and ceiling).

The CW rack profile is used to form the frame. It is most often installed in increments of 40 cm so that the seams of the plasterboard sheets fall on its surface.

Another area of ​​application for reinforced CW and UW profiles is plasterboard suspended ceilings, where the frame requires the highest possible spatial rigidity. Here their functions remain the same: creating a guide plane (UW) and a load-bearing sheathing (CW).

Soundproofing

If sound absorption concentrates sound in its designated place and volume, then sound insulation of the material “attenuates” the outgoing or incoming sound as much as possible when moving from one space to another. In addition to specialized options (where there are strict requirements for reducing outgoing noise), sound insulation is important for both residential and office premises. For example, sound insulation is very important in management offices, meeting rooms and other rooms where the dissemination of information is undesirable.

There are three categories of noise depending on the method of sound exposure:

• Airborne (we are talking specifically about airborne sound transmission - loud music, water noise, etc.)
• Shock (occurs due to mechanical impact - stomping, blows, moving objects, etc.)
• Structural (or mixed).

If there is a room on the floor above, it would be more correct to choose a mixed type of sound insulation; if there is no “threat” from above, then it is enough to protect the space from airborne noise.

Armstrong suspended ceilings can provide up to 95% sound insulation, that is, up to 44 dB.

On average, if there is no highly specialized, professional purpose, the premises usually use universal or multifunctional armstrongs, which have sufficient sound absorption and sound insulation characteristics at the same time. For example, Dune Supreme, Plain and others.

To ensure serious sound insulation, manufacturers produce specialized solutions - Armstrong Ultima dB, Perla dB and others.

Moisture resistance

The purpose of such ceilings is baths, bathrooms, swimming pools, laundries, hospitals, warehouses, food production, etc.

The moisture resistance of suspended ceilings usually ranges from 70 to 99%. For rooms with high or unregulated humidity, it is recommended to choose an Armstrong ceiling with a “ceiling” of 95-99%. Such a ceiling will not deform over time, will not sag, and will retain its original appearance and functional properties for at least 10 years. Of the Armstrongs, Duna Supreme, Newtone, Bioguard or use cassette suspended ceilings are suitable for this category.

Light reflection

This functional characteristic is not always considered significant, however, the level of comfort for those people who will work in this room depends on it.

In a space where direct light is not forced or intentionally used, the reflective ability of the ceiling plays a very important role.

Offices, conference rooms, waiting rooms, foyers - in addition to the utilitarian and design functions of lighting, the use of suspended ceilings with a high percentage of light reflection (from 85%) also provides additional energy savings of up to 25%.

Ceiling tiles with a high reflective parameter are, as a rule, smooth white tiles : Plain, Retail Board, Scala Winter and others.

Fire protection

Obviously, this characteristic has a particularly important priority in all situations. The fire resistance of the suspended ceiling must provide sufficient time for the evacuation of people from the premises in case of an emergency.

Armstrong ceilings have a fire hazard class from KM0 to KM3, which must be used in accordance with the class of the room.

Armstrong Ceramoguard and Newtone slabs are completely non-flammable and can even be used on escape routes. For comparison, the Armstrong Baikal ceiling has fire resistance KM1.

Let's sum it up

When it is necessary to solve any of the problems presented, we recommend that you use highly specialized slabs for suspended ceilings with appropriate properties.

If you just need to cover the ceiling and make the room beautiful and neat, then standard panels for a suspended ceiling that successfully combine all these properties will be enough.

Types of suspended ceiling modules

Manufacturers of Armstrong-type ceilings use different types of materials to produce modules. In this case, the composition can be standard or formed according to the client’s order.

Typically slabs include:

• mineral fiber;
• steel;
• polycarbonate;
• aluminum;
• basalt fiber, etc.

The texture can also be different - with or without embossing, with perforation, geometric pattern or decorative decorations.

Most often, slabs based on mineral fiber are used in interior decoration; their standard sizes are 600 × 600 mm (squares) and 600 × 120 mm (rectangles).

Characteristics - what may be indicated on the label of the slabs

The right choice in favor of Armstrong ceiling tiles or analogues with the same fastening system and composition can be made with a clear idea of ​​what information should be on the packaging.

Really high-quality products are distinguished by high fire safety indicators, which must be written on the label. In addition, the packaging may indicate the following technical characteristics of materials:

• presence or absence of asbestos;
• formaldehyde emissions;
• life time;
• category of mechanical strength;
• bending strength;
• sound absorption level;
• soundproofing;
• thermal conductivity.

Manufacturers indicate the absence of asbestos in products worthy of choice. This is an important point for products that meet GOST standards. Equally important is the level of formaldehyde emission. The lower it is, the higher the quality of the product. If these are Armstrong ceilings and analogues, then it is better to choose slabs marked E1 - with the lowest level of formaldehyde.

Durability refers to the service life of slabs in a particular external environment. For example, class A products are most sensitive to humidity up to 70% and temperature up to 25 degrees. Class B boards are sensitive to humidity up to 90% at temperatures up to 30 degrees.

The most resistant products are class C and D. The former react to humidity above 95% and temperatures from 30 degrees, the latter are practically invulnerable and are ideal for wet rooms with temperature changes.

Testing of products according to the criterion of mechanical strength category is not necessary in all cases. This parameter is considered relevant for slabs in which resistance to the external environment is the main criterion.

The flexural strength rating allows you to determine that the product can support its weight.

Most manufacturers regularly test suspended ceiling tiles for compliance with sound absorption standards, but information about this on the packaging is not often found. The reason is that sound absorption is just one of many parameters that influence the acoustics of a room.

As for sound insulation, a full assessment of the indicator can only be given through comprehensive testing of the suspension system complete with frame. That is why this data, regardless of what types of slabs are used, can be seen extremely rarely on the packaging.

An indicator such as thermal conductivity is not considered mandatory for inclusion on packaging in the list of board characteristics, so data on it can be obtained directly from the manufacturer.

Suspended ceilings type Armstrong

Armstrong suspended ceiling is a prefabricated system consisting of a metal frame and slabs pressed from mineral fiber. Suspended ceilings of the Armstrong type are popular for installation in private households and public institutions to decorate them in a classic style.

Builders and consumers have shown particular interest in this type of ceilings, because their installation is possible in rooms of any shape and size. The design is modern and attractive, and you can choose any slabs - environmentally friendly, moisture-resistant, fireproof, or of your own design.

Armstrong ceiling design calculation

To roughly know the material consumption for organizing an Armstrong suspended ceiling, you can use a special “online calculator”, which is posted on the seller’s website. Having, for example, the exact dimensions of the perimeter of the room and the area of ​​the ceiling base, you can calculate the number of required panels and components (aluminum guides, hangers, screws, etc.).

A simple calculation example:

Task: you need to make an Armstrong cassette perforated ceiling in a small office room (perimeter 14 m, ceiling base area 12 m2).

The data is entered into the online calculator in the appropriate fields. The following result is obtained:

• ceiling tiles – 34 units. (12.24 m2)
• wall corner 3 m – 5 units.
• lath 0.6 m – 17 units.
• lath 1.2 m – 17 units.
• support rail 3.7 m – 3 units.
• suspension – 9 units.

There are alternative calculation formulas, in which the area and perimeter of the room, as well as the dimensions of the components themselves, are taken as a basis.

Properties, technical specifications

Hygiene is a distinctive feature of Armstrong ceilings, so they have found their place in institutions where sanitary and hygienic conditions must be maintained at the highest level - in hospitals, pharmaceutical companies, other healthcare organizations, kindergartens and schools.

The technical indicators of Armstrong ceilings include:

• Open profiled covering;
• Installation on metal profiles lined with slabs;
• Standard slab sizes are 600×1200mm, 600×600mm;
• Fire resistance;
• Load bearing - 4-6.5 kg per m2 area;
• Availability of a wide range of accessories, the ability to integrate lamps, ventilation, air conditioners;
• Excellent sound absorption of vibrations in the range of 30-35 dB;
• conversion of a sound stream passing through a material into thermal energy;
• Reflection of light from ceiling elements up to 85%;
• Resistance to moisture – the slabs will not sag in a humid environment and will withstand humidity levels of 70-100%;
• Easy to maintain - cleaning is carried out with detergents and a sponge;
• Thermal conductivity – indicators meet the required standards;
• There is no risk of the formation of mold and fungal microorganisms, since the material has undergone special treatment with fungicides.

Types of profiles for drywall and their purpose

• Various lengths: from 2,500 mm to 6,000 mm. Thanks to this, it is easy to choose the required size, since it is undesirable to splice such load-bearing elements.
• The shelf height is standard and is 50 mm.
• Width – 50, 65, 75 and 100 mm.

The arched profile differs from other types in the presence of cuts on the side shelves, which allows it to be bent, giving the desired radius of curvature. UW (PN) metal profile guides have different widths. This is explained by the fact that the thickness of the partition being erected can be different.

Therefore, in the assortment of stores you can find UW profiles with a width of 50, 65, 75, 100 mm. Often craftsmen, when forming curved surfaces, do without using this type, replacing it with guides. Cutouts in the form of petals are made in its side shelves at certain intervals, as in the photo.

The smaller the bend radius, the more often the cuts are made.

• Small metal screws - for fastening metal frame parts together. However, professionals advise using a cutter for these purposes. It provides a smooth surface at the interface, while the heads of the screws can prevent the drywall from fitting tightly to the frame.

Types of ceiling systems

Since Armstrong is only a type of frame structure, depending on the slabs used (wood, steel, polycarbonate, aluminum, basalt fiber, gypsum, glass) the following are distinguished:

• plastic,
• plaster,
• metal,
• mirrored,
• glass,
• wooden,
• mineral modular.

The choice depends on the purpose and performance of certain functions.

Economy class systems are installed where hygiene, moisture resistance, impact resistance, durability, and acoustics are important.

Armstrong "Prima" are distinguished by high moisture resistance, fire resistance, increased acoustic properties, resistance to damage, and are equipped with a decorative structure.

Moisture-resistant suspended ceilings of the Armstrong type are applicable in swimming pools, baths, saunas, laundries, terraces, hospitals, warehouses.

Acoustic ones are recommended to enhance sound absorption. They are used to decorate restaurants, offices, swimming pools, hospitals, schools, hotels.

Medical modular ones are intended primarily for hospitals.

Hygienic ones meet all requirements for installation in healthcare institutions and the food industry.

Armstrong designer ones with original drawings will take their rightful place in elite premises of any direction.

The design can be embossed, perforated, with the addition of finishing from individual decorative elements, or combined into a single solid pattern.

Characteristics of Armstrong ceilings

Suspended modular systems for high ceilings can easily be called the best solution, and the Armstromg series in the line of suspended ceilings for office and public premises has virtually no equal.
Therefore, it is worth taking a closer look at modern Armstrong ceiling systems. Based on the design features, suspended ceiling systems can be divided into solid and modular. The plane of the second type of ceiling consists of modular (separate) elements, and is a collection of panels, slats and cassettes attached to the frame. There are two options for forming the frame. The first is that the frame is hidden behind the outer skin. The second is that it protrudes onto the front surface of the suspended ceiling.

Types of slabs for suspended ceilings Armstrong

• Mineral ceiling systems produced on the basis of mineral fiber - Armstrong type,
• plastic PVC ceilings Armstrong,
• wooden,
• plaster,
• Armstrong metal panels - divided into slatted, mesh "Griglyatto" and cassette ceilings,
• designer ceiling systems - divided into glass and mirror.

Ceilings differ in appearance, purpose, acoustic characteristics, weight, and technical characteristics.

It is important to know! It is impossible to visually distinguish between a false ceiling and a suspended ceiling, since the difference cannot be noticed by eye. It consists in the principle of fixing the frame of the suspended structure. If for a suspended ceiling the frame is attached to the walls and the base of the ceiling with a minimum gap, then the guides of the suspended ceiling system are suspended from the base ceiling.

Accordingly, for those who need to maintain the original height of the ceilings, it is worth organizing a suspended ceiling structure. A necessary condition for installing such a system is that the curvature of the ceiling base is small.

Advantages of modular suspended ceiling systems:

• aesthetics,
• practicality,
• good sanitary and hygienic parameters,
• low price,
• simple installation, as well as repair/replacement of components,
• the ability to hide utility lines in the inter-ceiling space,
• possibility of organizing recessed lighting.

Armstrong modular mineral ceiling

The interiors of modern offices are rarely complete without Armstrong ceiling structures. They provide sound insulation, improve indoor acoustics, hide utility lines, and regulate lighting levels. Lighting lamps and ventilation grilles can be installed in the frame of this design.

Mineral modular suspended ceilings include ceiling slabs and guides (suspended system).

Armstrong ceilings belong to the “economy” class suspension systems, and are intended for the decoration of retail spaces, public and office premises.

Economy class ceiling systems

- “Oasis Plus”, “Tatra”, “Cortega”, “Bajkal”, “Oasis”. These are functional suspended structures that can be installed in specialized rooms with high requirements for acoustics, moisture resistance, impact resistance, hygiene and durability.

Ceiling systems "Prima" type

- “Prima Adria”, “Prima Plain”, “Prima Casa”, “Prima Duna Plus”, “Prima Fine Fissured”, “Prima Cirrus”. This class follows the economic systems. Prima ceilings are characterized by high moisture resistance, fire resistance, increased acoustic parameters, resistance to damage and the presence of decorative textures.

Types of moisture-resistant ceiling structures

Armstrong moisture-resistant is also used in finishing rooms in which temperature and humidity conditions often change (swimming pools, laundries, terraces, hospitals, baths, technical areas, warehouses). Brands – “Milar”, “Newtone Residence”.

Types of acoustic ceiling systems

Armstrong acoustic is recommended for finishing premises with a high level of sound absorption - restaurants, schools, auditoriums, hospitals, hotels, offices, swimming pools. A separate type of modular suspended ceiling systems has been developed for medical institutions - the Armstrong medical ceiling. Brands – “Neeva”, “Frequence”.

Bioguard hygienic ceiling systems

Bioguard modular hygienic ceilings are intended not only for medical institutions. Since they fully comply with modern GOST, TB and hygiene standards, they can be installed in preschools and educational institutions, catering facilities, and healthcare institutions.

Types of designer ceiling systems

Armstrong designer ceilings differ from traditional office options. Such modular ceiling systems create elegant patterns and designs on the surface of the ceilings. Armstrong decorative ceilings are installed in retail spaces, cafes, entertainment venues, office premises, as well as in private homes. Brands “Visual V49”, “Cirrus Image”, “Graphis Diagonal”, “Cirrus Doric”, “Graphis Cuadros”, “Cellio”, “Graphis Linear”.

It is important to know! The given models of Armstrong decorative ceilings may have the same composition, but different texture, thickness or installation technology.

Brand names are given to simplify your search and familiarize yourself with decorative ceilings of one or another type in manufacturers’ catalogs.

There is only one drawback. The material does not fully resist moisture; after all, its basis is recycled paper, which can deform and become wet under the pressure of water.

Recommendations for selection

When choosing, you need to take into account the direct purpose, requirements for sanitary and hygienic, fire safety standards.

If humidity and/or temperature is unstable, it is better to use moisture-resistant models.

If enhanced noise protection is needed, acoustic ceilings are relevant.

In rooms with increased hygienic requirements - medical hygienic structures, the slabs of which are impregnated with a composition that prevents the adhesion of dirt, grease, and the growth of bacteria.

In bars, restaurants, hotels, palaces of culture - designer models. They will help give a special unique charm and interior.

Economic ceilings are suitable for cottages and country houses. They are strong, durable, high quality, and affordable for a wide range of consumers.

Advantages

Let's look at the main advantages of Armstrong suspended structures:

• The size of the room does not matter - Armstrong can be installed in both small and very large rooms.
• Most ceiling tiles are very light, which will avoid unnecessary load on the base flow.

• Only Armstrong is best able to hide serious defects in ceilings.
• Armstrong is indispensable where it is necessary to hide communications - it will successfully “cover” various cables, wiring, and hoods. In addition, if communications need to be repaired, then you will only need to remove the required number of tiles without disturbing the entire ceiling structure.
• Damage to one finishing element will not lead to the need to dismantle the entire structure - the ceiling tiles are easy to replace.
• Assembly and installation of the Armstrong ceiling does not require special knowledge and can be done by any home craftsman. Special tools are also not required - ordinary construction equipment will do.

• The materials used to make ceiling tiles are very diverse. You can easily choose the best price/quality ratio.
• The textures and colors of the finishing panels are very diverse and selecting finishes that suit the style of the interior will not be difficult.
• You can put insulation in the space between the main ceiling and the suspended ceiling and combine beautiful finishing and insulation - ideal for country house premises.
• If necessary, you can select panels with good soundproofing qualities - which is why Armstrong is often installed in clubs and recording studios.
• Most modern finishing panels are suitable for installation in rooms with high humidity.
• Modern finishing materials do not attract dust and, if necessary, are easy to clean and wash.
• All finishing panels undergo special certification and are safe for humans. They do not emit any harmful substances, and the slight odor characteristic of new plastic disappears within one to two days.
• Finishing panels are not susceptible to temperature changes, do not collapse or change color when exposed to ultraviolet radiation.

Cassette ceilings also have some disadvantages:

• Armstrong finishes may not suit all interior styles. For example, for classic interiors it is better to choose a simple matte stretch ceiling.
• In home interiors it may look “rustic”. To prevent this from happening, use original panel textures and effective lighting.

The cheaper the ceiling tile, the shorter its service life. Also, cheap options are usually not moisture resistant.

• Unfortunately, low-quality ceiling tiles can discolor when exposed to sunlight or begin to crumble when exposed to heat or cold.
• Ceiling tiles can be damaged by an accidental blow or scratch (children's pistols and slingshots, toy helicopters and airplanes, an accidental champagne cork, or simply an unsuccessfully thrown object).
• A suspended structure will inevitably “eat” 15-25 centimeters of the height of the room.
• Unfortunately, the design will not allow you to make any curvilinear figures - only straight lines or diagonals.

Installation Tips

Armstrong type suspended ceilings are installed easily and quickly, the system is simple. Finish 30-40 sq. meters of area for a team of 3-4 people per day is quite possible.

1. First you need to lay all communication systems under the future false ceiling.
2. When choosing, consider the weight, permissible load is 4-6.5 kg/m.
3. First mark the canvas horizontally in the room. When installing accessories, measure their height in advance in order to select the optimal distance between the base base and the ceiling during installation.
4. Use a water level when working so that the horizontal line around the entire perimeter of the room is drawn evenly.
5. Begin installation by fastening to the walls along the marked line horizontally. Use a hacksaw to cut profiles and a miter box to cut joints in corners.
6. Select fasteners taking into account the material of the walls themselves.
7. After assembling the structure, you need to check its horizontal evenness. Adjust as necessary by moving the petals or bending the wire in the right places.
8. Strengthen the frame by attaching additional hangers in the places where the raster lamps are installed.

Suspended ceilings of the Armstrong type are an excellent solution for arranging offices, medical institutions, and creating a favorable business environment. An ideal option for design in large public and private buildings.
