characteristics, scope + Video and Photo Alucobond composite panels: characteristics, scope. This material was invented in 1968 in Germany. The work on the project was joint - BASF and Alisuisse worked. As you can see, it was the names of the companies that became the basis for the naming of the new material. Alukobond went into production in 1969.

By 1986, due to the increased level of sales, a second factory line was opened. At the end of the 20th century, it was possible to sell 80,000,000 m 2 alucobond composite panels every year. In addition to Germany, there are also production facilities in China, USA, Switzerland, Russia and France. On the territory of the Russian Federation, the material is produced under the brand name "Aluk".

Production was opened relatively recently, in 2005 by the association of companies "Tashir".

Factory facilities are located in Krasnoyarsk and Kaluga.

Alucobond - what is it?

Alucobond is a composite material, and composites are those combinations that do not exist in nature. In this case, it is a combination of polymer and aluminum. The polymer is different in type and different in thickness, on which the operational parameters will largely depend. The name of the material has become a household name for blocks that are produced in different conditions and by different firms.

There are 16 companies operating in Russia alone, since in addition to Alukom, aluminum composite panels are made by Buildech, Alkotek, Krasran, Grossbond.

characteristics, scope + Video and Photo In this material, the aluminum sheets have a thickness of 0.5 mm. I grab the filler from both sides of the metal plates, and a sandwich is obtained. Most often, high-pressure polyethylene foam is used as a filler.

Aluminum sheets have an anti-corrosion coating, which prevents damage to the panels due to friction against the battens, as well as in contact with surfaces. An oxide composition is used as an anti-corrosion layer of the panels. Most often, sodium hydroxide solution is used, which belongs to anti-corrosion agents of inorganic origin such as phosphates, nitrates and chromates.

Sodium hydroxide makes it possible to create a film on the metal surface that prevents the contact of aluminum and moisture, and therefore prevents the metal from being destroyed. On the front side, the sheets are coated with polyester or fluorinated carbon, the latter being the most resistant to UV, chemical reagents and maximally flexible.

Thanks to their flexibility, the panels remain effective even when deformed, and the fluorinated carbon will never peel off or crack. In Russia, such a composition was developed by specialists at the Research Institute of Electric Coal Products, which is located in the Moscow Region.

The last layer in the sandwich is the laminated film, which must be removed prior to installation and is part of the packaging.The foil helps to protect the decorative cover during installation and transportation, but after the panels are installed, the foil can be removed. On the front side, the Alucobond composite panel for the facade has more layers, and if you count from the central polymer filler, then on the back side there are only 4 layers.

On the front side, on top of the polymer, there are 6 layers, and behind the adhesive layer and aluminum is a layer of primer, enamel, florobarbon resin and a protective film.

Varieties

Composite panels are produced under three brands. The first is called B2, which in no case should be confused with B1, because this is how the first flammability group is noted. B2 panels have 4 flammability groups, i.e.

the highest. These categories are regulated by GOST 30402-96. Such panels, in which case, will quickly flare up, and also quickly burn out. In the labeling, this feature was marked as G4, which means the highest degree of flammability. Smoke generation in category 3, but the smoke generation coefficient itself is over 500 units.

Also alucobond B2 has a low bending strength, 125 MPa. The width of the panels is also small, as is the cost, but it was the last factor that made the material quite popular for budget purchases.

Another brand is A2. In this case, the class is higher, since the group of flammability, flammability and smoke generation is the first. G1 is the minimum indicator.

By the way, there are also completely non-combustible materials that are marked with NG, but there are no such alucobond composite panels. The tensile strength is also 125 MPa, the thickness is similar, i.e. 3-4 mm, but the specific gravity is 1400 grams / m 2 more than that of B2, and all this with a thickness of 3-4 mm ! The third variety is plus, which is produced with maximum thickness. The specific gravity per 1 m 2 is 7.

3 kg. The bending strength is higher than that of the previous types, 240 MPa. Flammability and combustibility is minimal, but the smoke generation class is second. The blocks are called "plus" because the size is larger.

Sizes

Plus panels have a maximum width of 150 cm, which is 50 cm more than the minimum.

The first type of panels, B2, has a width of 100 cm. The second type of blocks is 125 cm wide. It is interesting that the second size A2 with a width of 150 cm is assumed, but it is extremely rare on sale. The standard length of the alucobond is from 240 to 500 cm, but atypical slabs can often be seen on the facades. This is due to the nuances of manufacturing the material, which is made with a continuous tape, and then only cut at the request of the customer.

The length can be adjusted according to the building designs. Although sizes may vary, they are not "rubber" either. The maximum length at which the technical characteristics will be preserved is 600 cm, but the width cannot be more than 160 cm.

Scope

characteristics, scope + Video and Photo Material is classified not only by types, but also by colors and textures. It will depend on them, for which style of the building the material will be appropriate.

There are blocks made of wood, metal, which can imitate stone. For private construction, the material is rarely used, partly the fact is that the type of aluminum composite panels is industrial alucobond.

To some extent, private traders try to avoid these panels because of the cost, but for the facades of high-rise buildings, entertainment and shopping centers, this is the best option, since industrialism is in place. However, there are some advantages of using the material, since, due to its low weight, it gives minimal loads to the foundation. Alucobond also has a simple installation scheme, which makes it possible to finish the facade and interior interiors of large buildings in a short time.

The fa├žade option is most often used, since the interior is rarely finished with composite panels. Also alucobond is in great demand for projects and billboards. If in facade work and when decorating buildings, the use is most often total, then for the private construction of houses the use of such panels, if it happens, is fragmentary.

Installation

The installation consists of 10 steps. The beginning of work is the fastening of brackets to the wall, which should be fixed with anchors with a drop-down metal sleeve.

After that, a layer of insulation should be laid, and only a fibrous material like mineral wool is required. Slots for the brackets should be made in it using a mounting knife.

Lay a layer of membrane (wind protection) on top of the insulation. The membrane and insulation should be secured with umbrella-shaped dowels. Attach a vertical metal profile to the protruding brackets, and its step will depend on the size of the panels.

It is permissible to use a regular profile, but best of all the alucobond "sits" on a special profile with a special fastening system.

Now you can attach the material cassettes to the profile, align and fix with self-tapping screws on the metal in the corners. When fixing, check the level of the screw caps so that they do not push through the protective layer of the panels. There is a support plate inside the vertical profile, and it can be pulled out with a screwdriver and brought onto the hook. In this position, fix the plate with self-tapping screws, which will reduce the load on the corner fasteners of the panels.

It remains only to install the cassettes according to the described scheme and maintain the same gaps between them.

Advantages and disadvantages

As you can see in the photo of the alucobond composite panels, they differ in shades and texture. Polymer films, which are used for covering the panels, come in any color, with different saturation, matte, glossy and overflowing. This variety is one of the advantages of the material. We will also attribute to the merits the simplicity of working with them - you will only need a standard set of tools for metal and wood.

Alucobond can be easily bent along the radius and angle, and it is also easy to cut and roll.

Also, the advantages include excellent sound insulation and thermal insulation.This is due to the layered structure of the panels and the porous polymer filler inside. The voids are filled with gases, and it poorly conducts both sound and heat waves, and all this with a material thickness of 3 mm. The porosity of the layer and the layering also reduce vibration, so finishing with such a material is beneficial in those objects that are located near the airport, railway tracks, landfills and industries.

Another advantage is durability and strength. Alucobond can remain unchanged from 50 to 200 years.

Cost

The price of the material goes by the piece per panel. One panel of a standard size costs from 3000 rudders (in German production), and some European-made versions cost from 2500 rubles. Russian and Chinese versions start at 1200 - this is the minimum price for one panel.

As you can see, the price is directly related to the quality, and also depends on the class.
