Finishing the facade with aluminum panels. Composite panels for facade Decorative aluminum plates

A popular product has the following layering sequence:

  • protective coating with anti-corrosion properties;
  • a primer to make the aluminum sandwich panel resistant to rust;
  • the first sheet of aluminum up to 0.5 mm thick;
  • plastic layer;
  • second aluminum sheet up to 0.5 mm thick;
  • primer layer of a composite based on polyvinylidene fluoride resin;
  • paint composition;
  • protective film.

aluminum panel can have a different thickness for a convenient choice in accordance with the tasks. Products of well-known brands have a non-combustible base.

Advantages of aluminum sandwich panels

The most significant advantages of products are light weight, fire resistance, durability, strength, reliability, elasticity. Aluminum composite panels are available in different shades. Color saturation does not change over time, traces of fading or cracking are invisible on the surface.

The aluminum composite can have a complex shape for decorating corners, oval objects. Products can be bent at an angle up to 180 degrees. The aluminum panel is processed in various ways - cut, sawn, bent, rolled, etc.

The boards are highly resistant to external factors. Aluminum composite panels are resistant to corrosion and chemical attack. They do not deform under pressure and shock. The aluminum panel withstands sharp temperature fluctuations. It is allowed to use plates in any climatic conditions.

The aluminum composite has excellent noise-absorbing properties, has a stylish and attractive appearance.

Scope of aluminum sandwich panels:

  • The slabs are in demand for arranging exhibition pavilions or other temporary demonstration facilities.
  • Restoration of old buildings. Panels do not exert additional load on structural parts.
  • Used for ventilated facades, for internal arrangement public buildings.
  • The material is laid on the walls and ceilings of airports, railway stations, car dealerships, cinemas, shopping centers.

To find out more about the characteristics of the material, submit a request through the online form. The Remeks company guarantees the minimum terms of order processing and fast delivery of aluminum panels in Moscow and St. Petersburg.

When arranging ventilated facades, special attention is paid to the cladding materials. It is on them that the durability of the coating depends, the protection of the building from negative factors and, of course, the external attractiveness of the facade. The most popular are composite panels, which have a lot of wonderful properties. More recently, their scope was limited to public and industrial buildings, but now such panels are being used to decorate private houses.

The term "composite" refers to the combination of several dissimilar materials into a single whole. What it gives: the new material acquires improved characteristics, which, in terms of quality and quantity, significantly exceed the properties of each of the constituent components. Any composite has a plastic base (matrix) and a filler acting as a reinforcing layer.

The structure of composite panels is more complex, since it also includes metal plates (most often aluminum) and additional layers to protect and decorate the finishing material. Each panel manufacturer may differ in the composition of the filler, the number of layers and the type of coating, but General characteristics remain unchanged: low weight with high rigidity and strength, resistance to negative factors and durability.

Aluminum composite panels "Alumatrix"

Externally, the panels are thin metal plates with a heat-insulating layer, square or rectangular in shape. The front side of the panels is covered with special paints and varnishes in a wide range of colors with a glossy and matt effect. More expensive options have a laminated coating that imitates the textures of natural and artificial materials. A variety of colors and textures makes it possible to completely transform the facade of any building, regardless of its size, configuration, architectural style.

Characteristics and types of panels

The standard composite panel has the following structure:

  • protective film;
  • paint layer;
  • aluminum sheet;
  • adhesive layer;
  • filler;
  • adhesive layer;
  • aluminum sheet;
  • anti-corrosion coating.

The panels are produced in widths from 1 m to 1.5 m, the standard length is 2.40, 3.20 and 4 m. True, many manufacturers do not indicate a fixed length, suggesting that customers choose the material for specific building parameters. The thickness of the panel is 2-6 mm, and the weight does not exceed 8 kg per square meter, due to which there is a minimum load on the supporting structures. At the same time, due to the small thickness and structural features, such a finish does not retain heat well, and as heat-insulating material not used.

The panels withstand temperature fluctuations in the range of -58°C ... +80°C, high wind loads, are immune to the effects of microorganisms and corrosion. In addition, they dampen vibrations and effectively absorb sounds. For example, soundproofing concrete walls increases by 2 times after the façade is clad with composite panels. As for fire safety, the indicators here are also very good: the panels are classified as flame-retardant materials that have low combustibility and emit little smoke. In addition, more and more manufacturers are using flame retardant additives in the manufacture of the material, which further reduces the risk of ignition of the skin in a building fire.

The panels are divided into types according to two criteria - the composition of the filler and the type of outer coating.

Type of fillerBasic properties
MineralMulticomponent composition, including foamed polyethylene and a large number of flame retardants. It has a low flammability class - G1, does not emit acrid smoke, does not spread when melted. German-made products use a filler made on the basis of aluminum hydroxide, which is even less prone to ignition. Panels with a mineral layer are designed for facade decoration
PolymericIt is made of cellular polypropylene and the made foam polyethylene. Such a filler provides lightness to the facing material, which allows it to be used when facing thin partitions and structures with weak bearing capacity. Panels with a polymer layer are used mainly indoors
AluminumAs a filler, very thin aluminum plates are used, collected in honeycombs or a grid. This ensures the greatest lightness of the cladding and the highest rigidity. Such panels can withstand huge wind loads, and therefore are ideal for finishing high-rise buildings.

It is worth noting that panels with aluminum filler absorb sounds much worse and do not hold heat at all, and the cost is much higher than the lining with mineral and polymer filler. For this reason, it is not advisable to use them for finishing a private house.

Varieties of panel coating

Coating typeMain characteristics
Polyester paints and varnishesThe most inexpensive type of coverage. Forms a strong and elastic film with a pleasant glossy sheen. It has good resistance to fading and moisture. It is recommended to use panels with such a coating for interior decoration, since from the outside they lose their visual appeal after 5-6 years
Paints and varnishes PVDFCoatings of this type have dirt-repellent properties, high resistance to mechanical damage and ultraviolet radiation. Their average service life is 20-25 years without losing their original appearance. Panels with this coating are excellent for exterior cladding.
oxide filmsThe coating resulting from the electrochemical processing of aluminium. It creates reliable protection against corrosion, ultraviolet, negative impact precipitation and mechanical damage, gives the surface a mirror effect. The average service life of such a coating is 15-20 years.
Laminating filmsThese synthetic coatings perform both protective and decorative functions. They create a skillful imitation of various textures: marble, granite, polished metal, various types of wood. Laminated panels are more expensive than others, but they also look the most impressive. The service life of these coatings is 15-20 years

Top Producers

Since composite panels are not yet widely used, like siding or corrugated board, not many companies are engaged in their production. There are about 30 noteworthy manufacturers on the domestic market, whose products meet the required standards. Wherein most of of these, these are Russian and Chinese companies, as well as their joint ventures. But the leader is still the German-Swiss brand Alukobond, whose composite panels appeared in Russia earlier than others.

Cladding technology with composite panels

This type of cladding is very expensive, but the result is worth it. Firstly, you get a reliable and durable design, which is not afraid of wind, precipitation, or temperature changes. Secondly, this finish looks incredibly impressive and stylish, standing out favorably among plastered or sheathed with siding houses. All work can be done independently, the main thing is to strictly follow the instructions.

Tools and materials

Composite panels are mounted on a subsystem of metal frame. Therefore, in addition to the facing material, you will need to purchase mounting brackets and a galvanized profile, two-stage drills for aluminum, a drill, and a building level.

To cut the panels, metal scissors, a hand jigsaw or a circular saw are used, and the sheathing is fastened to the subsystem using rivets or galvanized self-tapping screws.

Additionally you will need:

  • insulation (preferably in the form of plates);
  • waterproofing membrane;
  • primer for walls;
  • roller;
  • perforator;
  • marker.

Wall preparation

Composite panel cladding is suitable for all types of walls - brick, aerated concrete, wood, and so on. Before installing the frame under the cladding, the surface must be cleaned of dirt and repaired. The presence of through cracks, cracks, crumbling or moldy areas is not allowed. Therefore, all detected defects must be eliminated, cracks and large recesses must be repaired with mortar, if necessary, the walls can be re-plastered.

After the solution has dried, it is imperative to prime the base, choosing the appropriate composition: for wood, an antiseptic primer is used, and it is applied in 2-3 layers, for plastered walls - deep penetration strengthening primer. Minor irregularities do not need to be eliminated, since the hinged facade will completely close them.

Lathing installation

Step 1. Perform markings for mounting holes for brackets. The frame guides must be installed vertically, so the markings are done vertically. Departing from the corner of 10-15 cm, the vertical is determined by the level, and points are placed on this line with a marker in increments equal to the width of the panel. The distance between the lines is 50-60 cm.

Step 2 Using a puncher or drill (depending on the material of the walls), holes are drilled according to the marking, then they are cleaned of dust and dowels are inserted. After that, the brackets are assembled and alternately screwed to the wall.

Dowels are hammered, bolts are tightened

Step 3 Take plates mineral wool, apply them to the wall and mark the places for the slots for the brackets. Slots are easy to make with a sharp mounting knife. Again, the insulation is applied to the wall, stringing it onto the protruding mounting plates. In the same way, the remaining plates are installed, tightly joining them together and necessarily shifting the seams vertically.

Step 4 Attached over mineral wool waterproofing membrane, in which they also make slots for brackets. The membrane is fixed in horizontal stripes from the bottom up, with an overlap of at least 10 cm.

Step 5 To fix the insulation and the membrane, holes are drilled in the center of each plate and at 2-3 points in the corners, and plate-shaped dowels are inserted.

Step 6 Next, a U-shaped guide profile is mounted. Special spacer slides are inserted into the profile cavity - small movable plates that serve as a hook for the panels. The profile is attached to the brackets, leveled vertically, holes are drilled in the side part and fixed with rivets - 2 pieces for each bracket. At the junction, the profiles are connected with a mounting rail, which is also fixed with rivets.

At this point, the installation of the frame is considered complete. Make sure that all elements are on the same plane and securely fastened. The frame should not stagger and creak when pressed by hand.

Cladding installation

Step 1. The first panel is applied to the guides at the bottom of the crate, aligned along the bottom edge and horizontally. Fix its upper corners to the guide profile with self-tapping screws.

Step 2 Move the slide with a screwdriver to the upper side bracket of the panel and screw it to the profile with a self-tapping screw. Further, in the same way, the slide is strengthened at the bottom bracket and on the other side of the panel.

Step 3 Expose the second panel. At the junction of panels, the gaps must be the same in width and not exceed 12 mm. Therefore, when installing, you need a ruler. The panel is leveled, the brackets are hooked onto the already fixed slides, screwed in the corners with self-tapping screws.

The top panels are mounted in the same way, controlling the horizontal and the width of the gaps. 2 methods are used to design corners: panels are joined exactly at the corners of the facade, leaving a gap along the entire height, or curved panels are mounted, giving a traditional angular or semicircular shape. For bending, a simple bending machine is used, consisting of a table, a pressure plate, clamps and a metal pipe of the desired diameter. The pressure plate is made of hard metal and then covered with a protective felt pad to avoid damage to the panels during bending.

The material is easy to process, so there are no problems with cutting if everything is done correctly. First, cut only in the direction indicated by the manufacturer. On the back of each panel, this direction is indicated by arrows. Secondly, before cutting, you need to take accurate measurements and mark the line with a marker or chalk, and securely fix the panel itself on the table with clamps.

Aluminum belongs to soft low-melting metals, so it must be drilled carefully, at low speed - from 500 to 800 rpm. If you need to immediately drill a large number of holes in aluminum panels, the drill must be periodically cooled with water.

An important condition: the drill must be very sharp, manual sharpening is not suitable here.

When bending panels, it is necessary to observe perfect cleanliness surfaces, since aluminum shavings or grains of sand that have accidentally fallen under pressure can leave scratches on the front layer, which cannot be eliminated. This will not only reduce the attractiveness of the lining, but also reduce its resistance to precipitation and ultraviolet radiation.

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

Manufacturing

Aluminum wall panels are produced by many factories that manufacture metal facades. Modern technology is indispensable. The whole process is fully computerized, thanks to which factories produce many units of goods in the shortest possible time. To give the aluminum panels their final shape, a bending method is used. The photo shows exactly how the process takes place:

There are manufacturers who specialize in creating custom-made aluminum panels. Before the production of aluminum products, all the information is discussed with the customer: thickness, color, dimensions, etc. It is possible to satisfy even sophisticated customers who need decorative curves, additional perforations and patterned carvings. For the ability to bend sheets on an individual order, you will need to pay extra.

Where applicable

The main area of ​​application is the cladding of 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 made into an attractive and rich design, many homeowners choose these products for facade decoration.

Varieties of aluminum panels

Decorative metal panels that can be used for interior and exterior finish, must match some 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 analogues. However, everything is due to the long service life, as well as other technical characteristics. Aluminum panels are painted with decorative compositions, treated with polymeric materials or simply polished until smooth.
  2. Panels of simple metal, which is rolled 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.

The aluminum profile for wall panels is treated with insulating material from the inside. As a result, they have increased noise absorption. Such a layer is made of 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 the second composition have similar characteristics. They allow you to muffle the sound.

There are several more types of aluminum panels that differ in scope and load capacity. This includes:

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

The cost of metal products reaches 700 rubles / 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

Not without reason the cost of facade aluminum panels is high. They have many advantages over other analogues for facade decoration.

List of pros:

  1. Light weight. The thickness of the material is small, so the finish does not heavily load the base of the building. Yes, and transport 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. The aluminum panel is durable and protects the wall surface.
  4. Long service life, which is at least 30 years. In practice, the lining withstands even more.
  5. Moisture resistant. The walls will be protected from negative influences, because the metal does not let precipitation through. The only weak point is the joints of the outer walls. They are sealed.
  6. A huge range of colors that allows you to create any facade, depending on the requirements of the customer. In terms of design, the panels are ideal. In addition, they are made with imitation of brickwork or natural wood.
  7. Good sound insulation performance.
  8. Resistance to influence of the alkaline environment and many acidic reagents.
  9. The material is not afraid of sudden changes in temperature, has good frost resistance. The coefficient of deformation with a change in temperature for products is the lowest.
  10. Simple finish. To use aluminum panels, you need a standard set of tools and minimal skills to work with them.
  11. Products do not rust, do not rot.
  12. The metal absorbs radio waves, so the building will be difficult to listen to.

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

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

Sheet mounting secrets

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

If we talk about installation, then it is not easy, however, with 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 installation metal crate. It is fixed to the wall with dowels. Brackets hold the entire structure, and panels are attached to the rails by means of bolts. Work begins at the top, gradually moving down.

Fastening system

Correct installation is possible due to the use of the 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. GT-10 profile. It has a groove width of 6 mm, dimensions 17x23.5 mm.

  3. Bracket for wall (GT-041). Length 5 cm.
  4. Latch (GT-06).
  5. Cassette holder (GT-07).
  6. Washer (GT-03).

When it comes to structures for outdoor decoration, they must be reliably protected. When creating a frame under the panel, which consists of internal and external corners, starting rail, connecting strips, finishing rail, trim and brackets, you need to follow the instructions and be careful so that the quality of the finish is the best.

Aluminium-composite panels are expensive, elite materials for facade finishing. Although they have a lot of advantages, only a few allow themselves to finish a private house.

Currently, the market for facing materials for facades presents a huge number of modern, quality products with many advantages over more traditional finishes.

Among the high-quality, new cladding options, one can single out, for example, aluminum panels designed for finishing the external structure of buildings, in particular, the facade.

What are aluminum panels

Aluminum facade products are complex composite panels. The design of such panels consists of 2 aluminum sheets, between which a layer of mineral materials or plastic is placed.

The thickness of an individual sheet can be from 2 millimeters, length - up to 6 meters, and width - up to 1.6 meters. Also on the market are facade panels non-standard sizes.

Aluminum cladding appeared on the domestic market relatively recently, but has already managed to establish itself on the positive side, thanks to a wide choice of colors and the highest functionality.

Aluminum facade panels: pros and cons

Any building needs finishing of external walls. One of the most modern and practical solutions to this problem is to install aluminum panels on the facade. This is a multilayer material consisting of thin metal plates and filler.

Aluminum panels are used in the design of industrial and public buildings, and sometimes private houses. This kind facing coating has a number of advantages and disadvantages.

What are aluminum panels?

Let's talk more about what aluminum wall panels, also called composite, are. Top and bottom The material is aluminum sheets 0.21-0.45 mm thick, with a mineral or polymer filler between them.

The total thickness of the panel usually does not exceed 6 mm, the width is 1.6 m, and the length is 6 m. Often the material is made to order, taking into account the architectural features of the building. On the inside of the panel there are special holes for removing excess moisture.

The front layer of aluminum can be covered with a special oxide film. It protects the metal surface from mechanical damage and impact. environment. The film can be transparent or decorative, giving the material various shades - bronze, turquoise, silver, etc. It is also possible to create the effect of a mirror surface, imitation of wood or stone. Read more about the properties of aluminum wall panels?

Varieties

The properties of the material and its ability to withstand external influences depend on the type of top coating and the use of various fillers. These characteristics determine the scope of the coating.

There are the following types of aluminum panels:

  • facade;
  • universal - suitable for interior and exterior walls, billboards, shop windows, etc.;
  • fire-resistant - can be used at objects with increased fire hazard, for example, at gas stations.

Selection and application

When buying aluminum panels for the facade, it is better to purchase products that come with a profile and fasteners. Otherwise, improper fasteners can lead to deformation of the finished coating and reduce its strength.

For the design of the facade, standard material is usually sufficient. Thicker panels are needed only for buildings located in areas with frequent precipitation and increased wind loads. They are made to order.

As already mentioned, aluminum panels are a versatile material that has found its application in various fields. They are used for lining the interior and exterior walls of shopping centers, small detached buildings (car washes, gas stations, pavilions, technical rooms), for creating billboards, various stands. Sometimes aluminum panels are used in cottage construction, this is especially true if you plan to design a high-tech house. More about salient features high-tech style?

Specifications

Despite the presence of metal in the composition, the weight of the panels is relatively small - about 3-7 kg / m? depending on thickness. This allows you to use the material on almost any wall, in most cases you can do without strengthening the foundation.

The warranty period starts from 25 years, as in Alucobond facade panels, and can reach 50 years. The material withstands temperatures from -60 to +120 ° C (the range depends on the properties of the filler), sound absorption is in the range of 20-30 dB.

The sheets have good elasticity and can be bent at an angle of 180 degrees. This makes it possible to clad facades complex shapes, decorate arches, make smooth bends.

Mounting Features

Most often, aluminum panels are used in the construction of a ventilated facade. Work can be carried out at any time of the year. Read more about the construction of a ventilated aluminum facade?

Due to its plasticity, the material is easy to install, but in order to get a high-quality coating, you need to follow a number of rules:

  • Use a milling cutter or electric jigsaw to cut the panels, while fixing the sheet on the clamp. When fixing, the use of rubber gaskets is mandatory.
  • The frame is made vertical. It is built from the parts included in the kit, the step between the profile is determined based on the weight of the material.
  • Fasteners are used only from stainless steel.
  • Be sure to conduct a geodetic survey of the building before starting installation. According to her data, brackets for the frame are exposed.

After installing the guides, additional thermal insulation of the walls is carried out with a suitable slab insulation. A moisture and windproof film is placed on top of it.

Next, the installation of aluminum panels is carried out. They can be mounted hidden, open or hinged. Work begins in the direction from the bottom up. In the first case, the panel is fixed on the racks with screws, the upper edge of one sheet is connected with a groove to the lower edge of the next one.

In the second version, the panels are applied with a slight overlap and fixed with screws. With a hinged mounting method, the sheets of material are fastened with bolts, there are rubber gaskets at the joints of the sheets. The latter option is preferable because it simplifies replacement individual elements when repairing a coating.

Advantages and disadvantages

Aluminum façade panels are in demand due to their stylish look, in line with modern architectural trends. In addition to this, the material has outstanding technical characteristics.

Among the main advantages of aluminum panels are:

  • long service life (up to 50 years);
  • high class fire safety;
  • flexibility and plasticity;
  • universality;
  • ability to absorb noise;
  • resistance to corrosion, moisture and temperature extremes;
  • resistance to ultraviolet, allowing the material to retain its original appearance for a long time;
  • easy cleaning with water;
  • many color solutions;
  • moderate weight of the material.

In contrast to the positive properties, there are several disadvantages, namely:

  • The outer surface of the material is unstable to mechanical damage, especially in the absence of additional protective coating. Aluminum panels are easily scratched, which affects their decorative properties. For this reason, the material is not suitable for finishing areas where increased resistance to damage is required, for example, the basement of a building.
  • The cost of such panels is quite high, which is understandable, since they are characterized by increased strength and belong to elite finishing materials.

Aluminum panels for the facade open up space for various design solutions. They meet all the requirements for modern finishing materials, and will become great choice for those who want to make the house more stylish. When buying high-quality aluminum panels and their professional installation, the owners can be sure that the walls of the building are reliably protected and will retain a presentable appearance for many years.

Aluminum panels on the facade: types, application, installation


Aluminum facade panels are used in the cladding of industrial and residential buildings. Aluminum in their composition guarantees durability and a stylish look of the material.

Everything about composite panels for the facade: from selection to installation

Composite material of any kind has long and deservedly enjoyed high popularity. This principle itself - the layer-by-layer connection of metals, polymers and even wood, in order to modify properties, has been known for a long time. The uniqueness of modern options is explained in the choice of such compositions and the accuracy of the connection of materials.

Aluminum Composite Panels

The simplest design involves two aluminum sheets with a layer of polymer or mineral filler. In addition, the product is protected by a primer, paint and varnish composition and a protective film.

At first glance, aluminum does not need such numerous means of protection. The material is distinguished by high chemical activity, which in this case turns into an advantage: aluminum instantly oxidizes and forms an oxide film on the surface. The latter is insensitive to the action of moisture. However, so useful features are inherent only to pure metal, and although the sheet is cleaned in production, it undergoes chemosynthesis, but, nevertheless, it does not provide such a high purity or uniformity.

Composite facade panels can be even more complex. But there is also a limiting factor: more quantity layers, the thicker the panels, and, therefore, the heavier they are. And one of the most positive qualities aluminum facade cladding - lightness. 1 sq. m. of material weighs only 3-8 kg, which allows you to form products of large sizes. The photo shows an example of aluminum cladding.

Finishing of well-defined standard parameters is produced. However, with the manufacture of atypical products - both in size and shape, there are no difficulties.

Composite panels have the following dimensions:

  • length - from 244 to 580 cm;
  • width - 120 or 155 cm;
  • thickness - from 2 to 6 mm, depending on the complexity of the composite.

Technical characteristics of facade cladding

The quality of the material is determined by its components: the purity of the aluminum sheet, the nature of the filler, the use of one or another polymer paint. Common user properties of composite panels include the following.

  • The highest resistance to corrosion - both the material of the racks and the protective layers provide a 100% guarantee;
  • The low weight reduces installation time to a minimum. It is possible to trim with your own hands.
  • The material, of course, does not have thermal insulation properties, but it absorbs noise quite successfully. The secret is to use the thermal break material as a spacer between the two aluminum layers. The layer equalizes the temperature, due to which, when the upper aluminum sheet is heated, the second one almost does not heat up and, accordingly, does not deform. The same polymeric material also provides a reduction in the effects of cold.
  • Aluminum composite panels retain their user qualities in the temperature range from -60 to +120 C., and installation is allowed even in frost.
  • The decorativeness of facade panels is ensured not only by color or texture, but also by the high elasticity of products. The sheet can be bent at an angle of 180 degrees, which allows you to veneer curved facades, smoothly rounded corners, arches and the like.
  • Resistance to mechanical stress and ultraviolet gives the products a decorative and protective layer. Most often, polyvinylidene fluoride enamels with acrylic resins are used for this.

However, the choice here depends on the destination. Cladding with composite facade panels requires maximum resistance, so the use of fluorocarbon compounds is fully justified. But for interior work, the modules are painted with a thin layer of polyester-based paint, since resistance to UV rays is not important.

  • The upholstery is very easy to clean - a jet of water is enough, the surface is not electrostatic and does not accumulate dirt and dust. The interior finish is wiped 3-4 times a year with a damp cloth.

The material is not resistant to shock loads: the surface is quite easy to crush or scratch with a blow, therefore, during installation, it is not advised to remove the film. It is also allowed to use only special fasteners and preferably "native".

Mounting Features

Aluminum composite panels are a specific material. Firstly, it is still designed for use in large areas, for ventilated systems for the facade and other things. Secondly, from a design point of view, its most attractive characteristic is its elasticity, the ability to bend and cut. However, it is difficult to do this with your own hands and without equipment.

  • You can use a jigsaw to cut products, but a sawmill or a milling cutter shows the best results. In this case, the sheet must be clamped on a clamp, using rubber gaskets for protection.
  • The frame for cladding is constructed from special vertical guides, which are attached to the wall with brackets, also specialized. The step between the guides and the fastening frequency is determined by the weight of the sheet.

  • Installation of composite panels is made from the bottom up hidden or open way. The first, of course, is more popular: the product is fixed with screws to the racks, and the bottom edge snaps into the groove of the underlying element. The open method differs in that the next module is overlapped and secured with screws.

  • Fasteners are made of stainless steel. In this way, the danger of a galvanic couple is prevented.
  • Another mounting method is hanging mount, to implement with your own hands is more difficult. The panels are bolted to U-shaped racks. On the sides of the sheets in this case there are rubber pads that prevent slipping.

Composite panels for aluminum facade: characteristics, do-it-yourself installation


Description of the features and applications of aluminum composite panels.

Installation technology of aluminum facade panels made of galvanized steel

When choosing the type of exterior finish of a house, two methods usually compete - applying a layer of plaster (“wet” method), or a cleaner and faster ventilated facade.

It is a sheet of sheathing materials installed with a small gap above the wall surface, which creates a ventilation gap that helps to remove steam and moisture from wall materials.

A ventilated facade is a convenient way to clad a house without the dirt that is common for “wet” finishing methods. Siding or its variety - facade panels is used as sheathing.

They successfully perform the functions of protecting wall materials and have a powerful decorative effect on the viewer. Such qualities contribute to the continuous increase in the varieties of facade panels, one of which we will consider in detail.

Distinctive features of aluminum facade panels

Aluminum composite panels (for simplicity - aluminum composite or ACP) are a modern facing material for exterior walls of buildings.

The inner side of the panel, facing the wall, is covered with an anti-corrosion layer, and the outer side is covered with a protective layer that protects the surface from exposure to ultraviolet rays, atmospheric manifestations, etc.

The outside can have a natural metallic color, or can be painted in various colors - from white to black. In addition, imitation of wooden or stone surfaces, mirror coatings or coloring of pearl shades is possible.

There are samples of aluminum composite series "chameleon" that can change its color depending on the angle of view, for example, from dark green to bluish-pink, etc.

Advantages and disadvantages

The advantages of ACP include:

  • High decorative qualities.
  • The light weight of the material does not create an extra load on the supporting structures of the building.
  • Lack of ability to burn.
  • The ability to easily endure the entire temperature range possible for outdoor use.
  • Moisture and frost resistance of the material.
  • Ease of installation, the ability to install at any time of the year and in any weather.
  • Service life (guarantee) - from 50 years.
  • There is no need for special care, ordinary rain is enough.
  • Wide choice of material colors.
  • Automatic transmissions can be dismantled and reused.
  • High material cost.
  • AKP are not heat-insulating. On the contrary, the temperature of the outside and inner sheets should be as uniform as possible, otherwise the sheets will begin to bend in one direction or another. Therefore, during installation, spacers must be used between the support brackets and the wall.

The disadvantage that can affect the choice is the price, but high quality, durability and stylishness of the skin are quite consistent with such costs.

Specifications

Aluminum composite has the following specifications:

  • Length - 2.1-6 m.
  • Width - 1.22-1.5 m.
  • Thickness - 4 mm.
  • The thickness of the aluminum layer is 0.4-0.5 mm.
  • The temperature change in the length of the material is 2.4 mm/m at a temperature of 100°.
  • Relative elongation - 5% maximum.
  • Panel weight - from 3.7 to 7.9 kg.
  • Filling with flame retardants on the inner layer - 75%.

What distinguishes AKP from other types

Aluminum Composite - material that can change your form- for example, you can give the sheet a concave or convex shape (for sheathing non-flat surfaces), bend the panels up to 180 °.

In addition, it is possible to cut the material in any direction with any tool, the main thing is that it does not damage the decorative coating and does not spoil the appearance of the aluminum composite.

Another property that distinguishes AKP from other types of plating is high level of sound insulation.

This is in contrast to, for example, vinyl samples, which make a lot of noise when it rains. The reason for this quality is the multilayer structure of the material, capable of extinguishing sound waves and not create resonators.

Despite the fact that the basis of the material is metal, they are light in weight, which significantly reduces the load on the supporting structures of the building.

With large wall sizes, light weight is a significant advantage, as the building's supporting structures may not be designed to carry a large additional load.

Other types of facade panels

In addition to aluminum, there are other types of facade panels.

All of the listed types of external cladding materials have approximately the same installation procedure, since they all belong to the same type of ventilated facades. The greatest difference between them is in the material of manufacture, its features and requirements for operation.

Types of aluminum panels

Aluminum panels for exterior wall decoration are divided into:

  • Aluminum cassettes.
  • Perforated panels. They are used for enhanced ventilation of walls - for example, in places of high humidity or increased steam emission.
  • honeycomb panels. An aluminum honeycomb is installed between two aluminum sheets. The material has increased rigidity, low weight and the possibility of manufacturing large format sheets - up to 2 m by 9 m. At the same time, the sheet thickness is from 15 mm, but in terms of rigidity it exceeds 5 mm sheet steel by more than 3 times.

In addition, there are aluminum ceiling panels, but they are intended for interior decoration.

Together with aluminum, galvanized steel panels are produced using the same technology. They are somewhat heavier than aluminum, demanding on the type of processing (destruction of the protective layer causes corrosion processes).

Otherwise, galvanized steel panels practically do not differ from aluminum panels either in installation technology or in operating parameters, the only difference is a slightly more low price material.

Installation instructions

The installation of an automatic transmission begins with the installation of the crate, or, as it is more commonly called, the subsystem. Need to form load-bearing structure, a frame made of specialized metal parts that forms a system of slats that form a flat plane.

  • First of all, you need to make markings on the wall. The mounting locations of the brackets attached directly to the wall will be marked.
  • Vertical rows of brackets are marked 45-50 cm apart.
  • The horizontal distance between adjacent brackets directly depends on the size of the cladding.
  • The bracket consists of two parts, one of them is attached to the wall, the second is movable, it serves to fix the carrier profile and, at the same time, to adjust the even plane of the system. In this way, any unevenness of the walls, which may interfere with the smooth installation of the skin, is compensated. The bracket is fastened to the wall with an anchor dowel, through a foam pad, which serves to prevent the formation of a cold bridge.

  • The movable part is fixed after the plane is adjusted two aluminum rivets (minimum), for which holes are drilled. For installation, a rivet is used.
  • To adjust the plane first an ideal vertical is established along the two extreme rows, then a cord is pulled between them and all other rows are adjusted.
  • If it is necessary to insulate the facade, then first the marking and installation of brackets is carried out, then the insulation is installed (tightly, without gaps), after which the plane of the subsystem is adjusted. In places where the console must pass through the insulation, it is necessary to make a cross-shaped incision, pass the console through it and tightly lay the insulation around it without cracks and gaps.

  • After installing the subsystem, you can start installing the automatic transmission. It is made with the help of spacer slides, which are inserted into the guides above. The panel clings to the slide, brackets are placed on its sides, with the help of which fixation is carried out on the slides.
  • All nodes are mounted on aluminum rivets, which exclude corrosion.. The gap between adjacent panels should be 10-12 mm (temperature gap to compensate for thermal expansion). The corners are set in the same way as the panels themselves.

Conclusion

Aluminum façade panels are a modern and stylish way to finish a building, giving it a new, futuristic look. An even canvas appears from smooth, reflective or imitating natural materials panels.

They distinguish the building from the general familiar visual range, give it an urban look, characteristic of the most modern architectural finds. The operational qualities of the cladding make it possible for air exchange between the materials of the walls or insulation and the atmosphere without the penetration of moisture from the outside.

The strength and durability of the canvas make the sheathing a reliable shell that protects the building from all external influences.

Aluminum panels for the facade: advantages and disadvantages, installation of facade composite panels made of galvanized steel


This article is devoted to aluminum panels for a galvanized steel facade, their pros and cons, as well as the installation technology of facade composite panels for exterior decoration of a house.

Facade aluminum panels

The use of aluminum for exterior decoration of building facades has long become commonplace. In addition to durability, accuracy and respectable appearance, exterior finish hinged aluminum systems perfectly combined with the technology of ventilated facades. With the growth of energy saving requirements for buildings of all classes, ventilated facades are gaining more and more popularity.

Types of aluminum facade panels

Depending on the architectural solution, the height of the building, the fire resistance class of the structure, the selection of the most suitable type of aluminum panels for the facade is carried out.

The design and installation of aluminum exterior trim is regulated by building codes. For each facade, based on the geometric parameters of the building, an individual project is developed.

According to the method of manufacture and application, there are several types of aluminum panels and cassettes:

  • Aluminum composite panels or cassettes from a three-layer sheet, from two layers of aluminum with a plastic layer between them, from 2.5 mm to 6 mm thick;
  • Aluminum panels without a plastic interlayer from a solid aluminum sheet, from 1.5 mm to 2.5 mm thick: flat or three-dimensional aluminum cassettes;
  • Perforated aluminum panels on the facade;
  • Aluminum ceiling panels;
  • Aluminum honeycomb panels for sound insulation;
  • Aluminum panels for advertising structures and signs.

The last three types of panels are not facade, so we will not dwell on them in the article.

Regardless of the type of cassettes or facade panels, their manufacture requires special equipment, including CNC machines.

Application of aluminum panels

Facade panels made of aluminum organically fit into the modern dynamic architectural style with subtle details. This finish is perfect for buildings of shopping malls, auto centers, entertainment and entertainment, as well as business centers, and even industrial buildings.


Wall aluminum panels are most often used for internal partitions or cladding, their use as an external facade decor or as independent enclosing structures is unnecessarily expensive. This niche is almost completely occupied by wall sandwich panels with an outer layer of steel.

Limitations of the scope of aluminum composite panels


The limitation in application is the destructive effect of wind loads and fire safety requirements, in particular, when erecting structures of class F1.1 and F1.2 in terms of functional fire hazard. These include:

  • Preschool educational organizations;
  • Specialized nursing homes and disabled people (not residential);
  • Hospitals;
  • Sleeping buildings of educational organizations with the presence of a boarding school and children's organizations.

When installing ventilated facades, the issue is considered comprehensively, the use basalt insulation in the project prevents the spread of fire.

The federal law "Technical Regulations on Fire Safety Requirements" prohibits the use of aluminum panels for explosive and fire hazardous buildings of class A, B, in particular for gas stations.

Exceptional features of the use of perforated cassettes: media facade

Perforated cassettes for the facade are a new architectural trend that is gaining momentum, actively using the effect of chiaroscuro and the work of the surface through the light. The effect of voluminous media facades is achieved by multi-level and multi-plane ice illumination. The contrast of perforation without illumination against the background of blank concrete walls is also interesting.


The perforated facade is also found on sports facilities. Some stadiums in Russia have decor on the facade - perforation in the form of a running person or other athletes.

Aluminum panel decors

Composite sheet has a resistant outdoor painting bright saturated, or vice versa, soft pastel colors.

The most common panels for aluminum facades light gray silver color, having a metallic sheen. This color is produced by most Russian, European and Asian manufacturers. Due to the fact that the outer aluminum sheet is painted before thermal bonding of all layers, in order to order a different shade, you need to familiarize yourself with the manufacturer's color catalog. Non-standard painting is also possible, if it is planned to order a large (usually over 500 sq.m.) amount of material. Color catalogs from different manufacturers differ in the degree of gloss and shades, you should order the entire volume from one supplier. The type of surface depends on the method of applying the finishing layer:

  • One-color painting is carried out on the basis of PVDF and a PE-polymer structure based on polyester varnish. Such a coating contains synthetic fluorocarbon or fluorocarbon resins of increased strength;
  • For the "mirror metallic" effect, an additional layer of oxide film is used;
  • The method of electrochemical anodizing achieves metallized surfaces, such a surface is often used in interior decoration to create mirror "silver" and "gold" surfaces.

The exterior finish of aluminum panels looks impressive in the form of brushing, small scratches on a dull gray background create the illusion of stainless steel.

Composite aluminum sheet for facade panels can have outer surface imitating:

  • Valuable wood species;
  • Polished granite or marble;
  • Fantasy non-geometric ornament.

Depending on the difference in the application of the outer coating, its service life varies:

  • Polymeric PVDF and PE painting - 20-25 years;
  • Chemical anodizing - 15-20 years;
  • Decors with stone or wood imitation - 15-20 years.

During this period, the surface of facade aluminum panels is guaranteed not to fade or change color. Paintwork will last longer, but may slightly lose the brightness of the shades.

Aluminum panel production

The basis for the manufacture of facade panels from a solid or composite sheet is the use of an aluminum building alloy.


How aluminum sheet is produced

Aluminum building sheet is produced by hot and cold rolling followed by annealing. For manufacturing, an alloy with a high content of manganese AMg6 is used. This provides the necessary rigidity to the finished product.

Depending on the final decor, a galvanized coating up to 14 Mk thick is applied to the sheet by the electrochemical method for subsequent powder painting and applying a paint layer. In order to preserve the visible structure of the metal, an anodized layer is applied with a thickness of up to 40-60 microns, followed by protection with a special varnish.

The painted sheet is delivered in separate sheets, usually 1500x2500, 3000 mm. Aluminum the composite sheet has more effective dimensions, 1200, 1250x 6500 mm, which minimizes waste when cutting. The exception is Chinese material, which is shipped by sea, its dimensions are limited by the size of a sea container.

Composite aluminum sheet consists of two aluminum alloy plates with a thickness of 0.25 mm to 0.5 mm with a thermally bonded and pressed plastic layer between them. The front surface is painted before the plates are connected to each other and is protected for ease of transportation with a protective PVC film, often with the manufacturer's logo. The film is not removed even when cutting the sheet; already finished products are released from it.

Often, with an abundance of the same size in working conditions only cutting of blanks is performed, so it is more convenient to take out the cassettes for installation, and final assembly into a box with edge trims is carried out directly at the facility, where a mini-production site is equipped for these purposes.

Stages of production of aluminum cassettes

The production of aluminum cassettes begins with the calculation of the required amount of material for the implementation of a specific project. To do this, the area of ​​​​all facades is calculated, excluding the area of ​​\u200b\u200bwindow and door openings. When assessing the required amount of aluminum sheet, it is taken into account that the cladding with cassettes lags behind the surface of the facade by at least 100 mm. The size of the flanging and cutting of the sheet is also taken into account.

On average, the ratio of the net area of ​​the facade to required quantity aluminum sheet is 1.25. After the production of working documentation for each cassette and for the elements of the subsystem, the material enters the workshop.

Types of ACP interlayers

To solve various architectural problems, the composite sheet is always produced for facades of 4.04 mm and with different ratios of the aluminum layer and the inner plastic lining.

For high-rise buildings with increased requirements for safety and fire resistance, a composite aluminum sheet is produced with an internal flame-retardant layer with asbestos.

Outwardly, such facade panels made of composite aluminum sheet are easy to distinguish, they have an inner layer of white or light gray color. One of the most famous trademarks of such a composite sheet is Alpolic, it is used to make the cladding of the most famous skyscrapers in Dubai and the Moscow City North Tower.

The inner layer of the G1 class composite aluminum sheet can also be black. Upon purchase, in addition to the information in the label on protective film a certificate must also be required. The use of cheaper facade panels made of class G4 composite sheet is prohibited, as it can lead to possible fires with a very rapid spread of fire over the surface, with high temperature combustion and the release of many toxic gases. The unscrupulous use of material for the manufacture of panels has already occurred in Russia.

The thicker the layers of aluminum in the composite sheet, the more reliable the facade panels made from it will be. For buildings above 18 m, it is allowed to use cassettes with aluminum layers of 0.4 and 0.5 mm. For low-rise buildings, for reasons of economy, you can use a composite sheet with 0.3 mm aluminum alloy interlayers, usually a Chinese-made material, but it is better to avoid such solutions.

Advantages and disadvantages of aluminum sheet facade panels

Facade panels made of a solid (without inner layer) aluminum sheet are the most durable exterior finish option that does not require maintenance in the form of tinting for many years. Besides:

  • aluminum is practically not subject to rust and is easily powder-coated in many shades according to the RAL scale;
  • aluminum facade panel refers to conditionally non-combustible materials, facade panels from it can also be installed on high-rise buildings without additional approvals.

The disadvantages include considerable weight, with an aluminum density of 2700 kg / m3, 1 m2 of a cassette made of aluminum solid sheet 2 mm thick, weighs 5.4 kg, which creates an additional load on the building envelope and foundation.

A considerable weight has to be taken into account when designing horizontal and vertical aluminum rails, to fasten the bearing brackets with more powerful anchors and higher rates of resistance to shear loads.

For facade planes formed from a single sheet, additional measures According to the grounding device, aluminum is known as a very good conductor of electric current.

Facade panels made of aluminum sheet do not dampen the noise from falling raindrops

Advantages of facade aluminum panels made of composite sheet:

  • Excellent flatness of surfaces;
  • Light weight (one and a half times less than panels made of solid aluminum sheet);
  • Perfectly dampens the sound of rain, has noise-protective properties, due to the inner layer of plastic.
  • relatively low fire resistance;
  • the impossibility of tinting and tinting, colors only according to the manufacturer's passport.

Aluminum panels for the facade usually have the form of a flat box with a side height of -18-22 mm, but it is possible to manufacture radius cassettes for curved surfaces or complex three-dimensional structures with kinks along the plane.

How to work with aluminum panels

Facade panels made of solid and composite aluminum sheet provide beautiful surfaces with minimal joints from 2 to 60 mm, for hanging cassettes during installation. Aluminum facade panels are box structure, rectangular or other geometric shape with flanging along the edge for fastening. The top and bottom corners are cut with a special press.

The bending of a solid aluminum sheet is performed by a manual or mechanical press-bending machine. The thicker composite sheet is milled before bending. This ensures bending of the material with minimal radii and beautiful surface interfaces. The corners are connected with rivets and reinforced with aluminum square elements.

Prior to the manufacture of panels, to select the optimal size, taking into account the waste as a result of cutting
aluminum sheet, their ability to withstand wind loads, especially at height, is calculated.

Usually cassettes are made from already painted sheet. For cassettes made of solid aluminum sheet, it is possible to repaint already finished products. For good flatness and the absence of lenses (sagging of the cassette centers under its own weight), large-sized panels are made with additional rigidity - corrugated aluminum inserts.

Fastening system for facade aluminum panels

Several systems of different brands have been developed for mounting on walls, but the general principle of fixing panels on the facade is close.

Metal brackets are installed on the wall surface, from 100 to 250 mm long in the form of the letters G or P. The length of the brackets is set by the thickness of the outer wall insulation. A system of vertical metal profiles-guides is installed on the brackets, on which facade cassettes are hung. The panel subsystem can be either aluminum or steel. Hanging takes place on the slide in the cut grooves in the flanging of the cassettes. Or through ikli - special hooks, usually there are four of them on the cassette. Typical units of ventilated facades based on aluminum facade panels are available in the catalogs of the subsystem manufacturers.

Corner joints for the ends of the building, junctions to window structures, interface between the wall and the roofing surface by lining the parapet have been systematically developed.

For three-dimensional panels, standard nodes are finalized by building up, or an individual fastening system is developed.

Methods for applying perforation to aluminum sheet

Aluminum panels with through cuts in the form of ornaments are used for the manufacture of facade panels - screens, for decorating the facade over translucent glazing or for decorating opaque surfaces, as well as for creating media facades. Moreover, any shapes are possible, the only limitation is that the area of ​​the cuts should be no more than 55% of the total surface area, otherwise the aluminum panels cannot withstand wind loads, bend and break.

Cutting is performed in a single sheet different methods depending on batch size:

  • Small batches - cut out with a cutter of a special cutting plotter, according to the same principle as volumetric letters;
  • For solid aluminum sheet for small batches, laser cutting can be used, giving excellent accuracy and pattern repeatability. The disadvantage of this method is its high cost;
  • For the manufacture of large batches over 1000 sq.m. you can use a punch press.

Major manufacturers of aluminum panels

The world leader in the production of aluminum sheets for the subsequent manufacture of facade cassettes is the international concern ALCAH, which has production facilities around the world.

On its basis, such well-known brands as Alucobond, Dibond and Alpolic, Japan are produced. The equally well-known Reynobond brand is based on Alcoa, France aluminum sheet.

This is the highest price, but also high-quality group of materials for the manufacture of facade aluminum panels.

Slightly lower in the price range are composite sheets of Russian and Turkish production. In the lowest price group, but with quite acceptable quality, there are Chinese suppliers of aluminum and aluminum composite sheet.

Aluminum façade panels are an ideal material for implementing any architectural ideas, as it is easy to give it the desired shape due to bending and cutting. In combination with a variety of colors and surface textures, this exterior finish creates a unique look for buildings.

Facade aluminum panels


Aluminum façade panels blend seamlessly into modern dynamic architectural style with laconic details. This finish is perfect for

The outer walls of any building need finishing: and not only because they need protection from the effects of precipitation, but also to give the entire building an architectural identity - otherwise, all the houses will be on the same "face". Aluminum cladding panels are designed to solve this problem.
What kind of material is it, and how it is used in facade decoration, we will tell you in this article.

In production 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, has a low weight, soft enough, which simplifies its processing. And the price of aluminum is not an example lower than that of steel, and even more so of copper and its alloys.
    These properties are the criterion that affects the choice of this metal as a raw material for the manufacture decorative coatings for facades.
  • Facing aluminum panels, or as they are also called: composite panels, are a multilayer, and rather complex structure. And this is despite the fact that their thickness does not exceed 5 cm.
    For one or another manufacturer, the technology for assembling panels is practically the same. Unless different types of raw materials are used to fill the core and decorate the front layer.

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

  • If the building is typical, inexpensive standard options that are easy to assemble with your own hands are quite suitable for finishing it. Moreover, upon purchase, you will be offered everything in the kit. necessary materials for the frame, including fasteners.
    The manufacturer's instructions are also included. Before starting work, it’s good to watch the video - and you will succeed.
  • It is very convenient to buy all the parts in a kit - 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 with a larger diameter, which makes the connections mobile.
  • Therefore, it does not make sense to try to save money by buying a cheaper profile or fasteners from another manufacturer. This is fraught with deformation of the lining, even if it seems to you that all the elements are the same size.
    When the cassettes are made for a specific building, they are numbered and must be installed strictly according to the assembly scheme.
  • In this case, the joints of the cladding with window openings and entrance groups are also detailed. Wiring diagram, as a rule, also provides for the direction of assembly of elements: from bottom to top, or from left to right.
    An individual mounting method can also be developed, depending on the dimensions of the panels and the wind loads that they will experience.
  • From the same considerations, the choice of panel thickness is also made. For example, for a high-rise building, or a low-rise building, but located in a climatic zone with a predominance of winds, the thickness of the metal can be increased in the design of the panels, or additional fasteners can be provided.
  • The manufacturer accepts an order for the production of aluminum panels based on the technological specification. This document should reflect the following indicators: panel thickness; its coverage and color; the width of the seams and the location of the holes for fasteners; as well as raster sizes.
    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 is a sandwich panel with a length of six meters.
    They can be cut and bent, any modules can be made from them, and they can be connected together, including by welding.
  • This is very convenient when the building has a complex configuration, and makes it possible to clad 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 a cladding is about 9 kg per square meter.

Therefore, it is desirable that aluminum paneling 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 the cladding does not pose any threat.

How to work with aluminum panels

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

  • There are many articles on the assembly of ventilated facades on our website. 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 done during the cladding process. And there are a lot of them, and you need to professionally process the composite material.

  • 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, make window slopes, ebbs and parapets.
    Taking on such work, you need to know how it is done correctly.
  • Specialists who professionally deal with facade installation work, use stationary equipment that allows you to quickly perform large amounts of work. Basically, these are sawmills.
    Hand-held equipment includes circular saws and milling machines. The milling cutter allows you to accurately maintain the depth of the groove on panels of different thicknesses.
  • For cutting panels, you can use simpler equipment: a jigsaw, or a hacksaw for metal. 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 the formation of dents.

  • Aluminum panels are easy to roll. Special equipment is not required here, you can use a universal bending machine.
    When performing this operation, it must be borne in mind that the minimum distance from the edge of the material to the place of its bending must be at least five times the thickness of the panel.
  • If you multiply the thickness of the composite panel by 15, you get the value of the panel's minimum bend radius. By the way, you can bend the sheet in another way: by performing edging milling.
    So, if you have a small amount of work, a bending machine is not needed.
  • Wall cladding with aluminum panels can be done using screw connections. This is a visible fastening: in this case, the mounting sides of the two cassettes overlap and are screwed to the vertical post. The screw remains outside.

  • Hidden screw connection looks like this: the upper side of the panel is fixed with a screw to the rack, and the lower one is latched with a locking connection. The width of the seam, in this case, may vary, but must be at least 0.5 cm.
    To avoid galvanic influence of metals, all fasteners must be made of stainless steel.
  • There is another way to mount the panels - hinged fastening with bolts. They are inserted into the holes on the U-shaped racks facing outward.
    There are rubber pads on the mounting sides of the cassettes mounted in this way, 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 and multi-storey buildings.
    If you need to clad a small pavilion, or, for example, a warehouse, it is easier to use sheet material - it will also come out cheaper.

When mounted, it can be positioned both vertically and horizontally. 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 an exterior wall finish. So, choosing aluminum panels as a decorative cladding material, you will get a beautiful, reliable and durable facade coating.
