Today there are a lot of materials for finishing the facades of buildings. Not all of them have top quality, but many are worth the money spent. Please also note that it is not always high price provides good quality, durability and reliability. To choose finishing material The façade needs to be treated with all responsibility, since it is not purchased for one year!
Today, a composite made from a mixture of polymer and wood has increasingly begun to be used, making it very difficult to distinguish composite panels from elite wood. The most common installation method is mounted. It provides an opportunity not only to decorate the facade of the building, but also to insulate it and protect it from the wind!

Installation of composite panels on a ventilated facade
Today I will talk about how to properly attach composite panels to a ventilated façade. I will also consider the installation of the curtain facade itself, because this is also very important! You must not only memorize, but also understand the sequence of actions!

Frame construction
Making a frame for composite panels It is advisable to start with the correct markup. Let's start by marking our wall vertically. The number of marks must be equal to the number of profiles used. The hinged frame is the easiest to manufacture and maintain. Most likely, it is for this reason that it is used most often.
Next, we take the mounting brackets and, using anchor dowels, fasten them vertically at a distance of 50 centimeters from each other. As for the horizontal distance, it all depends on the number of profiles. Mounting brackets will be needed to adjust the plane.
Installation of composite panels
Supporting profiles are divided into several types: U-shaped, T-shaped and L-shaped.
I would like to draw your attention to the fact that the parameters of the console directly depend on the configuration of the supporting profile, so when you start making a ventilated façade, be sure to take this into account. I advise you to choose not the frame that is easier to make, but the one that suits you best.
In order to attach the supporting part to the console, you will have to drill holes whose diameter is equal to the diameter of the rivets. Two rivets are installed on the fastening. Less is impractical, more is unreliable.

Once all the planes are installed, it's time to start leveling them. To do this, you need to set the outer profiles perfectly evenly (we use a regular building level). As soon as the alignment manipulations are completed, take a nylon thread and stretch it between the outer profiles that were just aligned. The thread should be both above and below. Based on it, we align the remaining profiles. This turns out much faster than running around everyone's level.
Insulation of a ventilated facade
For high-quality insulation for a ventilated façade they use either polystyrene foam or the well-known mineral wool. These are the most common materials. Installation of insulation occurs only after the curtain wall is ready.
Installation of insulation occurs by pricking the material onto protruding consoles. Make cross-shaped cuts at the attachment point. When threading cotton wool or foam, carefully tuck it inside the frame so that nothing sticks out.
It is better to fasten polystyrene foam with construction adhesive, lubricating all sheets at five points (for greater reliability). Many people think that this is not enough, but due to the fact that the foam is lightweight and is also supported by consoles, the design is very reliable; nothing will fall off on its own.

To ensure reliability, mineral wool can also be secured with mushroom-shaped dowels. You can do the same with polystyrene foam, but it will be a waste of time and money.
Before fixing everything with fungi, I recommend installing a special wind barrier. This material will serve as both a wind barrier and a waterproofer. If you haven't found such material in your local construction stores, you can use high-density cellophane film.

Panel installation
In order to install the panel, you need to buy spacer slides. Their advantage is that they simultaneously serve as both a guide element and a fastener for composite sheets. There are special brackets on the side of the slide that secure the panels efficiently. The method is convenient, simple, and does not require much time.
Installation of a suspended ventilated facade.
The slides and brackets are secured with rivets. Some panels located at the intersection of the guides and tongues need to be attached to the same rivets. There must be a centimeter gap between the cassettes.
When it comes to design, composite panels come in the form of wood, stone or brick, so be sure to get the design right when installing.

Facade composite panels
Composite panels are manufactured in the most different sizes. The variety of shades and textures is also huge. Pricing is also based on these indicators. A striking example is panels with the addition of wood. They will cost an order of magnitude more than regular ones. You have to pay extra for quality, and this applies not only building materials.
Proven method self-insulation facade with mineral wool
For stylish and modern design residential buildings and industrial facilities often use special materials: aluminum and plastic panels. Composite facades are a striking example of how the covering of a building can perform several necessary functions: insulation, protection from destruction and improving aesthetic qualities.
What is composite
Ventilated facades are often made of wood and special plastic coatings that look great on the walls. But at the same time, the composite material used for cladding facades is more durable and affordable.

Composite is aluminum panels made using the sandwich principle. The design of the system is as follows: located in the center polymer coating, which serves as insulation, on the sides this polymer is fenced with two aluminum plates. This metal was not chosen in vain; it withstands temperature changes well, does not corrode and is known for its lightness, so it does not load the foundation of the building.
This is the main point why composite is used more often than porcelain stoneware. The latter requires a powerful foundation that can withstand pressure of up to 40 tons, and sometimes higher. It should be noted that due to its large mass, this coating also requires a reinforced frame.
Photo - curtain façade Composite panels that cover facades can be classified according to the thickness of the material inside the sandwich and the class of the building coating. Most often you can find a classification according to the flammability of the system, since this indicator is decisive when choosing a coating industrial premises. Exists several classes of composites:
- G-1 is a non-flammable material that perfectly resists direct fire and does not emit smoke. It is the safest, but also the most expensive;
- G-2 medium-flammable composite. It is characterized by a polymer filler of gray or white, marking and writing characteristics in the quality certificate;
- G-4 – filled with flammable polymer. It has black material inside, so you won’t confuse this coating. It is the most affordable, because it is approved for use only on non-combustible buildings for domestic purposes (dachas, garages, cottage houses, etc.).
Photo - panel design Non-combustible composites are also often used on residential or country houses made from timber or logs. Thanks to the presence of a large color palette, the owners of the building can decorate their cottage with composite facades without spoiling its eclecticism. In stores you can find a huge number of options for wood (pine, beech and larch), which can only be distinguished by a professional. But color options are also very popular: malachite, marsala, turquoise and others.

How to install a facade
Aluminum ventilated facades made of composite panels can be installed with your own hands or use the services of professionals. Independent work is much cheaper, in addition, it does not cost special costs time and effort.
Step by step instructions how to make a hinged composite facade with your own hands:
Composite boards for facades, aluminum cassettes and other types of coatings require special care to extend their durability. If necessary, it is advisable to clean the metal coating using special Kärcher sinks.
Aluminum composite material consists of two thin layers aluminum sheet, between which there is a mineral-filled layer.
Aluminum composite panels are used for facade cladding public buildings. The purpose of buildings can be very different; aluminum façade cassettes will look appropriate when cladding office buildings, shopping centers, exhibition pavilions, airports, train stations, hotels, gas stations, any other business centers in crowded places. Aluminum composite looks great in combination with glass. Composite cassettes often become the cladding of columns, pylons, and various protrusions on the facade of buildings. Sometimes they are also used for walls. interior decoration, for example, car dealerships.
- The advertising composite is on fire. There are no requirements for the composite. That's why they use G4.
- It's thinner. Facade panels have a thickness of at least 4mm; advertising panels have no restrictions on thickness.
Composite panels for the facade have a white layer. Historically, combustible composites have a black layer. The color of the layer is not a panacea. Unfortunately, it is too easy to fake a color in order to deceive the customer.
The external similarity of advertising and façade composites led to the use of cheaper ones as facade material. Those. cassettes from composite material were formed from flammable G4 sheet. Although aluminum facades can only be made from materials not lower than flammability group G1. This inevitably affected the composite panels.
In Russia, there are known cases of fires in buildings with facades covered with composite panels. Those 
cases where flammable advertising composites were used are notorious throughout the country. This is, for example, Grozny City or a residential building for the resettlement of Emergency Situations Ministry workers in Krasnoyarsk. The spread of fire quickly engulfed the entire building, leaving no chance of salvation. Because of these events, a decent modern facade made of composite panels was prohibited for use in some cities of Russia, the height of use was limited, incl. prohibited for use on buildings where people stay 24/7.
Now the situation with the use of composite facades has leveled off. In Moscow, facing 
composite panels are allowed again. Thanks to the realization of many that any quality material or the design can be damaged by violating the installation technology, especially by falsifying the products. The most popular ones are always counterfeited. It is imperative to approach with utmost care the issue of choosing the brand and supplier of the aluminum composite panel. You will become aware of some selection factors by reading this article.
How fire tests are carried out to assign a flammability group
All fire hazardous properties of the analyzed material are based precisely on the quality of the interlayer. Aluminum sheet itself does not burn and does not support combustion. Therefore, when testing for class assignment fire danger a group of factors is assessed:
- The calorific value of the inner layer must be at least 9.5 MJ/kg;
- Fire hazard class of building materials – KM1;
- Flammability group – not less than G1;
- Flammability group – B1;
- Smoke generating ability group – D2;
- Toxicity group – T2.
To check new material Fire tests are carried out to ensure compliance with these values. Accredited services are authorized to conduct fire tests. This is, for example: Kucherenko Scientific Research Institute (and the well-known expert A.V. Pestritsky), POZHAaudit; Research Institute Opytnoe and others.
What is the design of a full-scale ventilation façade sample for testing?
To conduct tests on a stove simulating part of a wall with a window opening, a full-scale sample of the structure with insulation and cladding is assembled. Everything is in accordance with the manufacturer’s Technical Solutions Album. They light a fire and, bringing it to certain temperature conditions, evaluate how the composite cassettes and the ventilated facade subsystem behave. Do pieces of more than a kilogram fall out? Do the pieces exceed the specified size? Does the fluidity meet the standards? Etc. In general, this technology is described in GOST. During the fire testing process, a Fire Test Report is drawn up. After the tests, based on the assessment results, the expert issues a certified Conclusion assigning a fire hazard class.
Is it always necessary to conduct full-scale fire tests?
It is important to note that sometimes experts do not need to conduct full-scale fire tests. For example, if the cladding being examined has already been “burned” with a similar subsystem of a different brand. In this case, an accredited organization authorized to conduct fire tests can issue an Expert Conclusion assigning a fire hazard class. The approach to the assessment is controversial, the issue of objectivity is debatable. Therefore, many manufacturers of subsystem installations for composite panels, and sometimes customers, insist on confirming the properties of the materials used.
How to check whether the Conclusion is an expert one or based on full-scale fire tests? Ask for a Fire Test Report. There is a protocol only for direct fire tests, nothing else is given. On the other hand, perhaps you should not be so picky about the Expert Opinion provided. The experience and reputation of the expert are too valuable and the risk of incompetence in the assessment is excluded.
How to check whether the delivered composite sheet to the site meets the criteria stated in the permitting documentation
During fire tests, a whole range of indicators is evaluated. Assessing all indicators together presupposes objectivity. Tests can only be carried out in accredited authorized organizations. However, some craftsmen consider it possible to conduct full-scale tests directly on site. For example, how do you like this assessment method: two panels are hung different brands on steel rods, two are installed at a distance of a meter gas burners, directed to the center of each sheet. They light the burners and see which one burns out faster...
This method does not carry any information. Key Factor in fire tests - this is the time 
combustion. A certain temperature is created in the oven. There will never be such a fire load on the facade of a building as when directed by a burner from a distance of a meter. Moreover, in places of increased fire load (especially the upper slope), special protective measures are taken during installation - fire shutoffs or ducts. Accordingly, the ability to resist fire increases. Do you agree? Share your thoughts in the comments.
Facade made of aluminum composite cassettes with a pattern
A composite sheet can be assessed for compliance with the declared parameters by concluding an agreement with an accredited organization. As a rule, these are the same institutions that are authorized to issue fire certificates. To carry out such an assessment, samples are taken from a batch already delivered to the site. From different pallets. Pieces 10*10cm, from 10 to 30 pieces. Sampling is certified by the Protocol and transferred to the expert laboratory.
The expert conducts mini tests on special equipment. Checks all studied indicators. And provides the test customer with a Conclusion on compliance or deviations. All expert institutes, as a rule, are located in central Russia, but there is a furnace in Zlatoust, Chelyabinsk region, you can order tests there too.
Automatic transmission performance characteristics
AKP - aluminum composite cassettes - light material, approximately 3-4 kg/m2. This means that it does not create additional load on the foundation of the building or the attachment point of the structure - the anchor; it can also be attached to aerated concrete and other porous concrete; There are no difficulties associated with movement during installation and transportation. For careful transportation, it has a top film layer on both sides, which is removed during installation.
The possibility of bending creates the prerequisites for wide constructive ones. Corner and radius bending allows you to beautifully design the corners of buildings and openings, as well as complex design delights.
Facade aluminum is produced in solid sheets with a width of 1220mm and 1500mm. The length can be any according to customer requirements, the limit is 8 meters.
The service life depends on the type of coating, but usually it is 25 years without loss protective properties and appearance.
Sound absorption, depending on the thickness of the cassette, is from 21 to 27 decibels.
Limitations of using composite cassettes on facades
There are many grades of aluminum composite sheets, but they must be selected according to their properties, which determine their suitability for use at sites with various structural fire hazards.
Important! A ventilated façade made of composite cassettes is prohibited for use in facilities belonging to functional fire hazard classes F 1.1. and F 4.1., according to Federal Law No. 123 “ Technical regulations on fire safety requirements."
For example, a perinatal center is a building with requirements for the use of non-combustible materials
Buildings F 1.1. - these are preschool buildings educational organizations, specialized homes for the elderly and disabled (not apartments), hospitals, dormitories of educational organizations with the presence of a boarding school and children's organizations;
Buildings F 4.1. – these are buildings of educational institutions, organizations additional education children, professional educational organizations.
The unifying condition of these buildings is the 24-hour stay of people or minors. This decision of the fire inspection authorities was motivated by the need to reserve time for possible evacuation from the building.
On buildings F1.1 and F 4.1 it is prohibited to use any flammable materials in decoration, including facades, i.e. related to the degree of flammability G1, G2, G3, and even more so G4, which is essentially a combustible material. The conclusion for many is disappointing: use only materials belonging to the NG class - non-flammable.
Anyone belongs to no better than G1. Even a composite brought from Europe and endowed with their local classification of flammability of materials FR - i.e. non-flammable, crossing the border with Russia it becomes G1.
Let no one be confused by the huge number of 24-hour facilities related to 
the above classes of structural fire hazard, made using aluminum facade cassettes. Amendments to Federal Law 123 concerning the topic under discussion came into force in 2014. Previously, it was possible to use composite materials on these buildings.
In connection with the entry into force of amendments to the law, a certain “prostration” arose in the cladding of controversial buildings. After all, when, for example, a building project kindergarten underwent an examination where the façade cladding was composite, it was approved. Then it was necessary to make changes to the project, and this in turn meant holding a new tender, because the terms of the contract have changed significantly.
ACP should also not be used on the façade of a nursing home.
The market does not stand still, and where there is demand, supply will come. As an alternative to aluminum composite cassettes, simply aluminum cassettes appeared. They have a large thickness of aluminum sheet and have absolutely no interlayer. Which would mean that the material would be classified as flammability group NG. But no. The problem is in the painting. The fact is that if a material is painted, even if it is not initially flammable, it is immediately classified as . Good news The fact is that it seems that manufacturers have learned to bypass this small nuance. You can read more in new articles on the website.
Your opinions, gentlemen...
Let's take a closer look at the option of cladding the facade with aluminum composite and discuss it in the comments
Not everyone can read the article to the end. And, if you are still with us, then curtain facades most likely form the basis of your professional activity. We do not pretend that the judgments in the article are the ultimate truth, but still this is a summary of experience, and the information will be useful to many.
If you have any opinions while reading, please speak up. The market for ventilated facades is as young as it is dynamic. Changes happen all the time. Manufacturers are improving the quality and expanding the possibilities of using their material.
The site's editors monitor updates, and we will be grateful if you tell us about innovations.
Architecture defines an era. Fashion comes and goes. But some trends remain for a long time as a successful mixture of aesthetics, functionality and technology. For modern buildings, especially commercial ones, ventilated facades have become almost an integral feature. How to new construction, and for reconstruction it is now difficult to find an alternative to composite panels for facades.
Features of ventilated facades
Curtain facades are decorative walls
, which protect the building from bad weather and exposure to sunlight. Since they do not carry structural loads, they can be made from lightweight materials. In this regard, a decorative composite facade is an ideal solution.
Panels on a building can serve not only for decoration, but also be used as a component of a multifunctional screen for walls - a ventilated facade. The essence of the technology is to provide space for natural convective circulation air between the building and the decorative shield. This allows moisture to ventilate and keep the insulation and walls dry.
To ensure the required ventilation gap, decorative cladding often mounted with a significant offset. In this case, the requirements for the weight of the shield can be very stringent - due to the large lever, they increase element loads fasteners, which can seriously affect the cost of the latter.
This is especially true for northern countries, where the thickness of the external insulation, together with ventilation gap, as a rule, amounts to more than a dozen centimeters. The weight of façade composite panels is small compared to steel, porcelain stoneware, natural stone, fiber cement and many other materials, which allows them to be used for mounted systems practically without restrictions.
Aluminum composite panels
Used in construction laminate, the outer surfaces of which are sheets of aluminum soldered together with a layer of polymer. The composite is produced under various trade names and comes in a variety of thicknesses and formats. Typical dimensions for sheets are 1000 mm, 1250 mm, 1500 mm and 2500 mm. Typical thicknesses are 3 mm, 4 mm or 6 mm for the entire “sandwich” and 0.2-0.6 mm for aluminum layers. Sheets intended for interior applications are usually thinner and may contain flammable polymers. Facade composites have a filling that meets the most stringent fire standards.
Combining aluminum sheets into a “sandwich” adds a lot useful qualities material in comparison with solid rolled products. First of all, this is a reduction in price by reducing the consumption of non-ferrous metal and replacing it with synthetic filling. The latter also helps to create an ideal plane for the sheets. In addition, the heterogeneity of the “pie” makes it possible to exclude the phenomenon of acoustic resonance in the material - this property makes the composite an attractive material for the manufacture of exterior finishing elements.
Advantages of aluminum composite panels:
- Plasticity and architectural expressiveness. Aluminum composite can be formed cassettes of various geometries: from standard rectangles to complex curved surfaces. The material is produced in a wide range of coatings of any color and texture.
- Strength and weight. In this respect, composite sheets are similar to rolled aluminum products - they are quite light and rigid for use as cladding.
- Low cost of maintenance. Resistant to atmospheric influences coatings make aluminum surfaces undemanding to use.
- Suitability for recycling. Aluminum is 100% recyclable and does not lose its quality after being melted down. Disposal other components sandwich production has also long been mastered by relevant enterprises.
- Non-structural benefits. They have good heat-shielding and sound-absorbing properties, which makes them attractive for use in industrial and civil construction.
Cassette manufacturing technology
From the point of view of manufacturability, the main advantage of the composite in comparison with solid material is a wide range of possibilities for processing sheets - methods of cutting, rolling, bending and molding, which are not typical for solid material. Some of these methods allow you to make quality bends by hand directly on construction site, which makes it possible to transport panels in flat pieces.
Basic technological operations when making cassettes:
- Cutting and milling. Can be carried out both on CNC machines and hand tools. By milling grooves, the edges of the future bend are defined or the ends are prepared for rolling. The geometry of the cutters determines the bending angle. After milling the grooves, the cut flat sheet can be formed into a volumetric cassette manually.
- Rolling. Performed on shafts to obtain cylindrical shapes. Allowable radii of curvature are specified by composite manufacturers for each material separately.
- Connection of cassette elements. The most popular method is a riveted connection using pre-drilled holes. If necessary, ensure tightness special tapes and mastics.
Installation of a composite facade
Support structure for curtain facades is a system of brackets and guides complete with necessary fasteners. The frame elements offered on the market by various manufacturers are not standardized. For budget construction(mainly for low-rise buildings) simple galvanized sheathing is used. Special subsystems made of aluminum are considered the best - this design load-bearing elements reliable and durable, lightens the frame, eliminates rusty streaks on the cladding, simplifies and speeds up façade work.
The installation of composite panels after leveling the frame itself is technologically simple. Finished and assembled cassettes are secured either hidden installation on the subsystem slide, or with visible hardware to the guides. At correct assembly The entire structure of the composite facade is not threatened by either thermal deformations or wind loads.
Ventilated facades are one of the most functional and aesthetic solutions in modern construction. Most likely, aluminum composite panels will be the favorites in exterior decoration for more than a decade. An hour's walk around any big city will confirm this assumption. Nowadays, the use of hanging systems is growing every year along with new infrastructure projects and the population’s need for residential and commercial buildings.
