The external walls of any building need finishing: and not only because they require protection from the effects of precipitation, but also to give the entire building architectural individuality - otherwise, all houses will look the same. Aluminum cladding panels are designed to solve this problem.
What kind of material is this and how it is used in finishing facades, we will tell you in this article.

In the production of metal panels for facade cladding, stainless or galvanized steel, copper and brass can be used. But, nevertheless, aluminum is most in demand in this field.
So:

• This metal is not afraid of corrosion, is light in weight, and is quite soft, which makes it easy to process. And the price of aluminum is much lower than that of steel, and even more so of copper and its alloys.
  These properties are the criterion that influences the choice of this metal as a raw material for the manufacture of decorative coatings for facades.
• Cladding aluminum panels, or as they are also called: composite panels, are a multilayer and rather complex structure. And this despite the fact that their thickness does not exceed 5 cm.
  For one manufacturer or another, the technology for assembling panels is practically the same. Unless they apply different types raw materials for filling the core and decorating the front layer.

• In the most affordable option, the core of the panel is under high pressure filled with cellular polyethylene. In more expensive types of composite panels, various additives are used for filling, including mineral ones.
  They improve thermal insulation properties cladding.
• The front surface of the panel can have a colored polymer coating, be enameled or powder coated. In some variants they are used protective films.
  Modular panels usually have standard sizes: square and rectangular cassettes 600*600 and 600*1200 mm. To remove condensation, special holes are provided on their reverse side.
• In most cases, aluminum cladding panels are made to order for a specific facility. After all, many modern buildings have complex geometry, and it is natural that they require individual cladding.
  Therefore, the dimensions and configuration decorative elements facades are determined using calculations.
• In such cases, even before the start of construction, a design project of the building is created, the method of finishing the facade, the material are selected, and its cost is calculated. A solid building, such as the one in the photo at the beginning of our article, will require considerable costs for cladding the external walls.
  But this is justified: the service life of composite metal panels is at least 30 years.

• If the building is standard, inexpensive ones are quite suitable for finishing it. standard options, which are easy to install with your own hands. Moreover, upon purchase you will be offered everything included necessary materials for the frame, including fasteners.
  The manufacturer's instructions are also included. Before starting work, it’s a good idea to watch the video - and you will succeed.
• It is very convenient to buy all the parts as a set - this guarantees full compatibility mounting holes and fasteners. In such designs, the thermal expansion of the metal is taken into account, so the holes for the screws are made of a larger diameter, which makes the connections movable.
• Therefore, it makes no sense to try to save money by buying a cheaper profile or fasteners from another manufacturer. This is fraught with deformation of the cladding, even if it seems to you that all the elements are the same in size.
  When cassettes are manufactured for a specific building, they are numbered and must be installed strictly according to the assembly diagram.
• In this case, the joints of the cladding with window openings and entrance groups. The installation diagram, as a rule, also provides for the direction of assembly of elements: from bottom to top, or from left to right.
  An individual fastening method can also be developed, depending on the dimensions of the panels and the wind loads they will experience.
• The same considerations are used to select the panel thickness. For example, for a high-rise building, or a low-rise building, but located in climatic zone with the predominance of winds, the thickness of the metal in the panel design may be increased, or additional fasteners may be provided.
• The manufacturing company accepts an order for the production of aluminum panels based on the technological specification. IN this document The following indicators should be reflected: panel thickness; its coating and color; width of seams and location of holes for fastening; as well as raster sizes.
  The raster is the distance from the center of the cassette to the middle of the joint.

• Composite aluminum panels are not only ready-made modules. There are many types of sheet material, which are sandwich panels six meters long.
  They can be cut and bent, made into any modules, and connected to each other, including by welding.
• This is very convenient when the building has a complex configuration, and makes it possible to veneer even a round surface, such as columns (see Finishing columns: doing it right). The front side of the aluminum panel can be not only smooth, but also perforated.
  The weight of such cladding is about 9 kg per square meter.

Therefore, it is desirable that cladding with aluminum panels be included in the project. First of all, this applies to facades with a large area.
The foundation of the building, in this case, must be designed for additional load. For a small building, such a weight of cladding does not pose any threat.

How to work with aluminum panels

Any façade lined with composite panels is ventilated. And by by and large, frames for installing modules of all types are made identically: three types of profiles, anchors, and brackets are used.
Mainly, only the methods of attaching the panels differ, which we will discuss further:

• There are many articles on our website on the assembly of ventilated facades. From them you will learn how to prepare the surface, mount the profile and insulation.
  We will talk about what operations with aluminum panels have to be performed during the cladding process. And there are a lot of them, and the processing of the composite material needs to be done professionally.

• The list of operations includes longitudinal and transverse cutting, milling, rolling (bending at an angle), cutting corners, punching for pins. Sometimes after cutting it is necessary to assemble a cassette and make window slopes, ebbs and parapets.
  When taking on such work, you need to know how to do it correctly.
• Specialists who professionally deal with façade installation work, use stationary equipment that allows them to quickly perform large volumes of work. Basically, these are sawmills.
  TO manual equipment can be attributed circular saws and milling cutters. The router allows you to accurately maintain the depth of the groove on panels of different thicknesses.
• To cut panels, you can use simpler equipment: a jigsaw or a hacksaw. But in this case, the complexity of the facing process increases.
  When processing an aluminum cassette, it must be clamped with clamps using polyurethane or rubber gaskets. They will protect the sheets from dents.

• Aluminum panels are easy to roll. No special equipment is required here; you can use a universal bending machine.
  When performing this operation, you need to keep in mind that the minimum distance from the edge of the material to the place where it bends must be no less than five times the thickness of the panel.
• If you multiply the thickness of the composite panel by 15, you get the minimum bending radius of the panel. By the way, you can bend the sheet in another way: by performing edging milling.
  So, if your workload is small, you won’t need a bending machine.
• Wall cladding with aluminum panels can be done using screw connections. This is a visible fastening: in this case, the fastening sides of the two cassettes overlap and are screwed to the vertical rack. The screw remains outside.

• A hidden screw connection looks like this: the upper edge of the panel is fixed with a screw to the rack, and the lower one is snapped into place using a locking connection. The width of the seam, in this case, may vary, but should be at least 0.5 cm.
  To avoid galvanic effects of metals, all fasteners must be made of stainless steel.
• There is another way to install panels - hanging with bolts. They are inserted into the holes on U-shaped racks, facing outwards.
  On the mounting sides of cassettes mounted in this way there are rubber gaskets, which will prevent them from sliding and rattling. This design allows you to easily replace the cassette during operation, if necessary.

• Facade cladding with modular and sheet panels is radically different in appearance. Modular composite panels are mainly used to create ventilated facades on large-sized and multi-storey buildings.
  If you need to veneer a small pavilion, or, for example, a warehouse, it is easier to use sheet material- it will also be cheaper.

During installation, it can be positioned in both vertical and horizontal directions. And the color variety allows you to create an interesting exterior of the building.
In the picture above you can see an example of such decoration of external walls. So, by choosing aluminum panels as a decorative cladding material, you will receive a beautiful, reliable and durable facade coating.

Aluminum facade panels are one of the highest quality types facing materials For exterior finishing buildings.

Aluminum facade panels are one of the highest quality types of cladding materials for exterior finishing of buildings. They are also used as protective screens in suspended ventilated facades. Among the many finishing materials, aluminum panels are distinguished by their light weight, strength, resistance to corrosion and other external influences.

Aluminum tapes are mostly used for the installation of seam roofing, as well as for objects with complex shapes (for example, with the transition of the roof into the facade, for rounded and wavy parts). A simple aluminum sheet can also be used for the manufacture of façade piece panels and the creation of decorative elements, including those with perforations.

Aluminum panels

Aluminum panels – finishing material, which is a “sandwich” of two aluminum sheets with a thickness of 0.28-0.38 mm and a polyolefin-based polymer layer located between them. Aluminum sheets are pre-treated and painted before joining into a panel. The polymer layer can have different thicknesses - usually from 1.5 to 5 mm. The thickness of the panel can be 2-6 mm. Most often, panels with a thickness of 3-4 mm are used. One of the disadvantages composite materials is the fact that they are only supplied in sheet form and only in a certain width, namely 1240 mm or 1520 mm.

As a result of a tight chemical-mechanical connection of two components, a product with fundamentally new properties than the properties of the original materials is obtained. The material is highly homogeneous (the sheets do not delaminate) and rigidity. The polymer layer absorbs impacts. As a result, aluminum panels can withstand significantly greater mechanical loads than any metal sheets with the same thickness as the thickness of the aluminum in the panels.

Due to their high rigidity, aluminum panels can be used both for finishing work (inside and outside) and for the construction of various objects. For example, for making advertising structures: advertising and transport signs, light boxes, signs. Aluminum panels are also used for the manufacture of parts for exhibition pavilions, exhibition and trade equipment, and branding advertising.

Aluminum facade panels at our facilities:

Decorative frieze made of perforated aluminum at the Luzhniki Stadium

In preparation for the 2018 FIFA World Cup, the Luzhniki Sports Association experienced a third birth. The global reconstruction of the stadium was carried out in accordance with FIFA requirements. The hallmark of the stadium was the frieze that goes around the arena. On the frieze tape, made of perforated Sevalcon aluminum, athletes froze in motion. The style of the images reflects the Olympic designs on Greek vases. The patterns are made up of holes of different sizes (perforation). The technical design of the frieze ensures good ventilation of the facade and fully complies with fire safety standards. The aluminum used on the frieze belongs to the NG category.

Ilgar Mamedov Fencing Center

The Ilgar Mamedov Fencing Center was opened in the spring of 2018; it is the final project of the sports and educational cluster “Olympic Village Novogorsk”. The architects had to decide not simple task. To create a building that is bright on the inside and elegant and warm on the outside. Natural light was used to illuminate the training spaces due to large areas of glazing. Warm heat was applied to the façade color scheme. Facade aluminum panels made from Sevalcon aluminum were used.

Metro station "CSKA"

The youngest station of the Moscow metro "CSKA". When decorating the station's interior, unique technologies were used to transfer images onto aluminum panels - sublimation. Main feature The process is that sublimation paint adheres only to polymer compounds. Sevalcon pre-painted aluminum completely satisfies technical requirements to metal for this technology.

Competence Center - Technical College named after S.P. Queen

In the science city near Moscow, Korolev opened its doors to the Interregional Competence Center - Technical School named after S.P. Queen. The educational building was built taking into account the strict requirements imposed on objects with large crowds of people. The facade of the building is made of aluminum facade panels.

Facade aluminum panels

For cladding buildings, facade cassettes made of aluminum with a thickness of 1.5 to 2 mm are used. Such a product has sufficient rigidity to withstand any natural mechanical loads on the facade. Unlike plasters, sidings and some natural materials(brick, tile, stone), metal panels are not so fragile. They do not develop chips or cracks.

Facade aluminum panels are light in weight - approximately 5-6 kg/m2. This is a very good indicator, given the high strength of the material. Installation of lightweight cassettes does not create additional load on the facade, and also does not require a reinforced sheathing structure. For this reason, aluminum panels are widely used for facade renovation.

For the manufacture of facade panels, factory-painted aluminum sheets or aluminum strips are used. Therefore, another protective barrier is added to aluminum’s natural resistance to corrosion and moisture.

Modern technologies for painting aluminum Coil Coatig allow you to apply a coating that does not fade in the sun, does not break with moisture and can be used even in an industrial environment or marine climate. Over time, due to adhesion processes, the coating made of polyester, polyurethane or polyvinyldefluoride fuses even more with the metal, so delamination is almost impossible.

The use of painted aluminum for facade panels allows you to significantly diversify appearance buildings. The color palette is very wide, and if the order is large enough, then it is possible to choose the color of the panels not only of any shade, but also of almost any texture (wood, stone, concrete, etc.)

Aluminum facade panels in various colors:

Aluminum panels, made from pre-painted PVDF coated aluminum, are highly machineable. They can be bent (the minimum bending radius is equal to the panel thickness multiplied by a factor of 1.5-2), cut, and perforated. You can most clearly see the advantages of PVDF-coated aluminum when performing such operations with metal as rolling it or making a seam seam, when covering a roof with aluminum. Rolling of metal - deforming it along a selected direction using special rollers (rollers). Essentially, rolling is a type of bending. A seam seam is a connection in which two blanks or two sheets of aluminum are fastened with bent edges pressed tightly against each other.

Due to this, aluminum panels with polymer coating PVDF is superior to composite material in its ability to impart various forms. Thus, aluminum panels can have both standard sizes (mainly in the form of rectangles) and complex shapes with convex or depressed elements.

The use of aluminum painted using Coil Coatig technology allows not only to obtain an even color across the entire volume of ordered products, but also excellent resistance to mechanical stress, the absence of microcracks at bend corners, and color fastness to UV radiation. An important factor is the price issue. Technological equipment Impol Seval plant allows us to offer our customers custom sizes tapes for the production of facade aluminum panels in the range from 60 to 1600 mm, which significantly reduces the amount of waste. Proper Use on the project thickness of façade aluminum panels, also leads to significant cost savings. As a result, the cost of using pure aluminum is comparable to the price of most high-quality facing materials.

Aluminum facade panels also have good sound insulation properties. The soundproof façade screen will dampen all external noise (useful for busy city streets), as well as internal noise (useful for industrial facilities).

Another property of aluminum facade panels is high fire safety. All products manufactured by the plant under the Sevalcon brand are certified not only according to Russian standards(GOST 30244-94, “The material belongs to non-combustible materials” (NG), but also according to the standards of the European Union - Category A1.

Conclusion

Thus, high strength, low weight, resistance to corrosion and other external factors, a wide variety of colors, sizes and textures, high sound insulation and fire safety, relatively low cost make aluminum panels an excellent choice for cladding buildings.

With their help, you can easily create the most daring in layout, original and sophisticated exterior designs in modern style and techno style. This is perfect for a variety of urban sites: high-rise residential buildings, business centers, shopping malls, corporate headquarters, medical and educational institutions, museum and exhibition centers, galleries, restaurants, cafes, beauty salons, pharmacies, gas stations, fitness centers, swimming pools, etc.

If we talk about repair work, then great value has the quality of the materials used, as well as several basic parameters. These are durability, strength, decorative qualities and affordable price. Although it’s better to pay once and not worry that the material will soon become unusable. One such material is aluminum composite panels. What is their feature, how to use the products and why they are so popular.

Manufacturing

Aluminum panels for walls are produced by many factories that produce metal facades. Without modern technologies can't get by. The entire process is completely computerized, thanks to which factories produce many units of goods in as soon as possible. To give the aluminum panel its final shape, a folding method is used. The photo shows exactly how the process occurs:

There are manufacturers who specialize in creating custom aluminum panels. Before the production of aluminum products, all information is discussed with the customer: thickness, color, dimensions, etc. It is possible to satisfy the needs of even sophisticated customers who need decorative bends, additional perforation and patterned cutting. You will need to pay extra for the ability to bend sheets to order.

Where are they used?

The main area of ​​application is cladding building facades. Moreover, it has been used in this area for a very long time. And if aluminum panels are rare in private housing construction, then gas stations, football stadiums, large warehouses, production workshops or large stores are often lined with metal panels.

Its relevance for such places is due to its high resistance to mechanical damage. But due to the fact that aluminum panels can be used to create an attractive and rich design, many homeowners choose these products for facade decoration.

Types of aluminum panels

Decorative metal panels, which can be used for interior and exterior decoration, must meet certain parameters. For example, fire safety, durability, strength, easy installation, good decorative qualities. There are several types of products that differ in the type of material used:

1. From non-ferrous metals: sheet of aluminum, copper. Their cost is much higher than that of their analogues. However, everything is due to the long service life, as well as other technical characteristics. Aluminum panels are painted with decorative compounds and processed polymer materials or simply polished until smooth.
2. Panels are made of simple metal that is rolled out on a machine. The size of the product is different, and the thickness is minimal. Such decorative elements can be made with your own hands using a hand tool for bending sheets along their length. This option is much cheaper. The surface is protected with paint so that the material does not rust over time. Unlike aluminum panels, metal panels can corrode when exposed to moisture.

Aluminum profile for wall panels The inside is treated with insulating material. Thanks to this, they increase noise absorption. This layer is made from soft plates on adhesive tape, the thickness of which is 1–4 mm, as well as from liquid spraying of polyethylene foam. Both the first and second compositions have similar characteristics. They allow you to muffle sound.

There are several other types of aluminum panels, which differ in the area of ​​use and the load they can withstand. This includes:

1. Wall metal products. They can be created in any shape, they can be square or rectangular. Installation can be done as desired, horizontally or vertically.
2. Aluminum ceiling panels. They are mostly made square and hung on a frame.
3. Decorative aluminum panels with perforated patterns. Such aluminum panels are produced by cutting holes according to the order. This is high-tech work performed in a factory. Used as a decorative material with ventilation holes. There are even backlit panels.

Price metal products reaches 700 rub./1m2. It all depends on the type of coating, as well as the metal used. Aluminum panels are the most expensive - more than 2 thousand rubles.

Advantages and Disadvantages

It is not for nothing that the cost of façade aluminum panels is high. They have many advantages over other analogues for finishing facades.

List of advantages:

1. Light weight. The thickness of the material is small, so the finishing does not heavily load the base of the building. And transportation will be much easier. This applies specifically to aluminum products.
2. Absolute fire safety. The material does not burn, therefore it complies with fire safety regulations.
3. Resistance to mechanical damage. Aluminum panel reliable and protects the wall surface.
4. Long service life, which is at least 30 years. In practice, the cladding can withstand even more.
5. Moisture resistant. The walls will be protected from negative influence, because metal does not allow precipitation to pass through. The only thing weak point– joints external walls. They are sealed.
6. A huge range of colors allows you to create any facade, depending on the customer’s requirements. In terms of design, the panels are ideal. In addition, they are made with imitation brickwork or natural wood.
7. Good sound insulation performance.
8. Resistant to alkaline environments and many acidic reagents.
9. The material is not afraid of sudden temperature changes and has good frost resistance. The deformation coefficient with temperature changes for products is the lowest.
10. Simple finishing. To use aluminum panels, you need a standard set of tools and minimal skills in working with them.
11. The products do not rust or rot.
12. Metal absorbs radio waves, making the building difficult to listen to.

As you can see, aluminum products have many advantages. However, there are also disadvantages:

• high cost;
• low thermal insulation of the building. You will have to install insulating material on the wall, covering it with aluminum panels;
• the material conducts current well, however, this does not affect the operation of the building in any way.

Secrets of installing sheets

Immediately before work, you need to buy panels, as well as stock up on tools and materials. We'll talk more about the fastening system below.

If we talk about installation, it is not easy, however, with the instructions everything is possible. Before installing metal wall panels, you need to remove the old finishing material. Plaster, falling tiles, plants on the facade.

The next step is to install the metal sheathing. It is fixed to the wall with dowels. Brackets hold the entire structure, and panels are attached to the slats using bolts. Work begins from the top, gradually moving down.

Fastening system

Proper installation is possible thanks to the use of a fastening system. All elements for work are made of aluminum alloy.

List of wall connection profiles:

1. Profile GT-08. It has a groove width of 3 mm, dimensions 19x25 mm.
2. Profile GT-09. It has a groove width of 4 mm, dimensions 17x23 mm.
3. Profile GT-10. It has a groove width of 6 mm, dimensions 17x23.5 mm.
4. Profile GT-11. It has a groove width of 8 mm, dimensions 17x24.5 mm.
5. Profile GT-46. Has a groove width of 3 mm.
6. Profile GT-47. Has a groove width of 4 mm.
7. Profile GT-22. Has dimensions 40x40x20 mm.
8. Profile GT-23. Has dimensions 40x40x20 mm.

List of aluminum profiles for creating a ventilated facade:

1. Main guide (GT-12, GT-052). Length 6 m.
2. Sliding bracket (GT-31, GT-32). Length 5 cm.
3. Wall bracket (GT-041). Length 5 cm.
4. Latch (GT-06).
5. Cassette holder (GT-07).
6. Washer (GT-03).

When we're talking about about structures for exterior decoration, they must be reliably protected. When creating a frame for the panels, which consists of internal and external corners, starting rails, connecting strips, finishing strips, trims and brackets, you need to follow the instructions and be careful so that the quality of the finish is the best.

Aluminum composite panels are expensive, elite materials for facade finishing. Although they have a lot of advantages, only a few afford to decorate a private home.
