One of the many important requirements for modern species facing coating is the ability to reliably withstand adverse environmental influences.
Hinged ventilated facades are a structure designed to protect the surface of load-bearing walls from various external influences.
First this method protection and finishing of the facade of the building, began to be used about 60 years ago. In the last ten years, the technology has become extremely widespread - a wide variety of coatings have appeared on the market and are used in private and multi-story construction.
In fact, curtain facades are not just one material.
In this article we will look at the main types of this facing coating. Despite the fact that each of the materials may have its own specific properties, first let’s list the characteristics common to all types.
Hanging ventilated system with imitation wood panels
So, curtain facades provide:
In addition, facade systems themselves are quite durable, beautiful and environmentally friendly. Any technical deficiencies none of the materials can be distinguished. The only disadvantage of any ventilated facade design is the high price for square meter.
Hinged ventilated facades for cottages are presented in more than 10 different types, differing in the material used:
Cladding panels porcelain stoneware
HPL panels installed with hidden fastening method
Combination of linear cladding in different colors
Hanging system with agglomerate granite coating
Suspended system using fiber cement boards
Cladding using glass and aluminum plates
Combination of composite panels various sizes and flowers
In addition, it is worth mentioning such products and coatings used to create hanging ventilated systems, such as:
They also have all the main advantages of curtain wall facades, but the disadvantages include only the disadvantages of the components used in production.
All types of facade systems are similar in their design, which is a multilayer structure supported by a rigid frame. This frame is mounted in a separate step directly on external walls building.
Such a supporting structure is presented in the form of a set of profiles and brackets, which allow you to level out uneven walls and install all profiles with maximum accuracy.
A ventilated facade for a private house usually has layers of various insulating materials:
Already on top of all this, the facing material itself is installed directly, which is not just a decorative layer, but also has all types of protective properties.
The design of the suspended ventilated façade is designed in such a way that each layer ensures full disclosure of the properties of the other layer.
It has already been mentioned that moisture protection protects the insulation from getting wet. The protection of the insulation from other types of external influences is provided by the topmost layer - it takes on all mechanical damage and weather influences.
Despite the fact that the production of ventilated facades involves the use of their own thermal insulation layer in many panels, during installation it is usually necessary to lay an additional layer of thermal insulation boards.
This is done even in hot regions - this will prevent the temperature in the rooms from becoming too high. For Russian conditions, installation is completely mandatory, since otherwise heating costs will be simply enormous.
If you think that the cost of heating or air conditioning may be lower than the cost of insulation, then pay attention to the fact that no matter the area of the surface to be covered, you only need to spend money on insulation once - the investment will pay off in no more than a year, and after that This will help you save on heating costs for many years.
For private housing construction, in most cases, it is customary to use mineral wool as thermal insulation.
A ventilated façade design usually involves the use of mineral wool. In any case, the insulation is attached to the wall using disc-shaped dowels. For every square meter of material there should be at least five such fasteners.
Begin laying the material from bottom to top. If the thickness of the insulation exceeds 15 cm, then it is laid in two layers, and then the seams are tied.
We have already mentioned mandatory waterproofing. When installing it, there is one feature that affects the installation order of the insulation:
The main types of ventilated facades have already been described above, but an additional classification can be made based on price.
In general, the cost depends on the following components:
Price various designs construction company Tatprof
For ventilated facades, the cost per m2 varies according to three price categories:
Porcelain tile cladding in terms of price/quality ratio is ideal for private housing
If you choose a ventilated facade made of wood, then of all materials it is preferable to choose a block house. This decoration will give the house the appearance as if it were made of round logs.
Despite the external similarity with massive logs, the thickness of the block house boards is 1.5 - 1.7 cm, which ensures very low weight. The low mass, in turn, eliminates the need to strengthen the façade.
If you need to decorate a house like a brick, it makes sense to pay attention to a ventilated system made of clinker tiles - such a material is close to brick not only in appearance, but also in its production method and some technical properties.
The substructure of facades made of all such materials will be similar to that described above - this is a frame, insulation, waterproofing and cladding.
Installation of a hanging ventilated system will cost from 1000 rubles per m2, provided that the work is done by yourself. If you hire specialists, then this price can be safely doubled - in fairness, it is worth noting that professionals will do everything truly to the highest standard.
Until recently, for some reason, the concept of “ventilated facade” remained beyond my attention. No, of course, I constantly came across this phrase, but somehow I never asked myself what a ventilated or, as it is also called, a curtain façade is.
I think it's time to correct this omission. If you enter the word “facade” into a search engine, almost all of the sites shown will contain an offer of these very ventilated facades. Since there are so many offers, you have to take it! But why? What is good about a ventilated facade and is it good at all? We'll find out.
So let’s see, based on these requirements, how close ventilated facades are to ideal. But first, let's figure out what this is. modern technology external decoration of buildings.
The ventilated curtain façade is a complex structure consisting of several layers:
Air gap- the main condition for a proper suspended ventilated facade.
There must be an air gap between the facing screen and the thermal insulation. This is the main feature of a ventilated facade. It is thanks to this air gap that condensation and atmospheric moisture are removed from the surface of the facade. In addition, such an air gap can significantly reduce heat loss, because the air temperature inside the structure is three to four degrees higher than outside.
The distance between the thermal insulation and the protective screen must be at least 20 millimeters. Compliance with this condition is extremely important. With a smaller air gap width, moisture will not be removed as it should, and this will, in turn, lead to the thermal insulation getting wet, increasing heat loss, increasing humidity in the room, making the insulating material heavier and, as a result, even to its collapse.
When installing a curtain facade, it is necessary to ensure free movement of air flows between the thermal insulation and protective layers. There should be no air obstructions either above or below the façade. To allow air to circulate freely, special perforated metal elements, installed in the upper and lower parts of the structure.
A variety of facing materials can be used for the protective screen of a ventilated façade:
What material you choose depends not only appearance building, but also the quality of the entire structure, because the function of the external screen of a ventilated facade is to protect thermal insulation layer from mechanical damage, wind, moisture, ultraviolet radiation. We will not consider the performance qualities of each of the facing materials; this has already been done in sufficient detail in another article. Let us only note that each material has its own parameters, which determine both the appearance and performance of the facade, as well as installation features.
External cladding elements are attached to the sheathing (load-bearing sub-cladding structure) in two ways - by visible and invisible fastening. In the second case, the facing elements are attached using special grooves on the inside, so that the fastenings remain invisible. The invisible method of fastening the cladding allows for greater aesthetic appeal, but it is more expensive than the visible one. But the visible method also has its pitfalls. With the more attractive price of this method, it should, however, be taken into account that if there is a need to replace one facing fragment, the entire row will have to be removed. Often these two methods are combined: on the lower floors - at a height of 4-5 meters - they use the invisible fastening method, and above they use a simpler option - visible fastenings facing elements. In order to close the structure at the ends and at the corners, various inserts and corners are used, which make it possible to achieve the external completeness of the ventilated facade.
The load-bearing structure or sheathing is perhaps the most technologically complex element of the curtain wall system. The fact is that it is not enough to fix the brackets on the wall and attach them to metal profiles, onto which the cladding elements will then be hung. It is important to correctly design the sheathing and calculate it bearing capacity— the sub-cladding structure must withstand its own weight, the weight of the protective screen and insulation. At the same time, it must have sufficient anti-corrosion resistance, be durable and not too difficult to install. Conditionally everything possible options load-bearing structures of curtain facades can be divided into two groups:
The insulation used in curtain wall systems must also meet a number of requirements. It must have sufficient density - from 80 to 100 kg/m3. Otherwise, the wind will eventually begin to tear off pieces of material, which will lead to a decrease in the thermal insulation capacity of the facade. In addition, the insulation must be fire-resistant, durable, and have good sound-proofing qualities. Most often, mineral wool is used for these purposes.
Now, knowing what a ventilated façade is, we can consider its advantages and disadvantages.
The scope of application of curtain facades is more than extensive. Today they are used on buildings for almost any purpose: administrative, residential, industrial. In addition, the installation of curtain facades is justified both in the construction of new buildings and in the restoration of old buildings. The only caveat is that curtained facades, as a rule, do not look very good on low houses. Therefore, from the point of view of aesthetic expediency, their installation is justified on buildings with more than three floors.
Installation of suspended ventilated facades is relatively simple and, most importantly, it can be performed at any time of the year, unlike the implementation of wet facades.
The installation of suspended facades does not require special preparation of the outer surface of the wall, as is the case with plastering, painting or attaching the cladding with glue or cement mortar. On the contrary, curtain facades will hide various defects in enclosing structures and can even, within certain limits, compensate for the damaged geometry of the building.
Thanks to the presence of an air gap, the thermal insulation qualities of the external finish are significantly increased, and the “exhaust” effect formed in it allows you to remove excess moisture and avoid its accumulation in the insulation layer and in the wall itself.
The materials used for the external cladding of curtain facades are resistant to aggressive mechanical and atmospheric influences and protect walls, insulation and supporting structures from them, thereby extending their service life. In addition, the design of curtain facades itself allows them to absorb thermal deformations that invariably arise due to daily and seasonal temperature fluctuations. This prevents the occurrence of material stress and, as a result, the occurrence of cracks and other damage to the cladding and supporting structure.
Curtain facades have a special aesthetic appeal. They are able to decorate a building, and their appearance is very diverse, which allows the implementation of various design ideas.
Against the background of such an impressive list of advantages of curtain facades, their shortcomings look somehow unconvincing, but they still exist. First of all, it is necessary to cancel the fact that today ventilated facades are quite expensive. In addition, all the advantages of a ventilated facade may come to naught if errors were made during its design. Therefore, you should trust all stages of the project implementation exclusively to professionals - you won’t be able to save money on contractors. I would include another drawback here - the service life is not long enough. Yes, the predicted service life of ventilated facades is 30-50 years. I wish it was longer. Don't you think so?
As you can see, there is nothing overly complicated in the system of curtain facades. It, like everything ingenious, is simple. Of course, the ideal still remained unattained, but whoever came up with the curtain wall system managed to get very close to it. All that remains is to wait for the price reduction for this type of façade finishing.
Natalya Vilyuma, especially for rmnt.ru
Since the facade of the house is the front part of the building, they strive to decorate it. But facade cladding is carried out not only with the aim of giving the walls an aesthetic appearance. The main task of finishing is to protect the facade from damage caused by environmental factors and to guarantee the building itself the longest possible lifespan.
This requirement, combined with the development of the industry, has led to the modernization of existing and the emergence of new facing materials and facade finishing technologies. One of these new products is a system of ventilated facades (ventilated façade).
Why is it needed, what is it, features, characteristics, properties, types, types and circuits of the device.
A curtain façade is a facade system made using a special technology, which consists of attaching the facing material to the wall using a frame (subsystem). As a result, there remains a gap (up to 100 mm) between the wall (facade of the house) and the cladding through which air circulates. In this way, moisture and condensation are removed from the structure and the heat transfer of the house is reduced.
The name itself reveals the essence of the system of suspended ventilated facades.
In general, a ventilated facade is a complex façade finishing technology that allows it to be provided with reliable protection from the destructive effects of various factors.
In short, to fully understand what a ventilation façade system is, you need to consider its constituent elements. Note that each of them is universal, which allows finishing complex architectural forms in different styles.
What does a ventilated façade consist of?
The fastening system includes load-bearing profiles, brackets, anchoring elements (dowels and screws), and special fasteners. The use of brackets for ventilated facades makes it possible to adjust the distance between the frame and the wall, so there is no need to level the surface of the walls;
Despite the fact that the fastening system is not visible, this is not a reason to skimp on its components. On constituent elements the main load comes from the weight of the facing material, the force of the wind and the movement of the air flow. Therefore, all materials used must meet quality standards.
There are several types of frames:
Subsystem for ventilated facades:
Thermal insulation material is not a mandatory part of a ventilated façade. If the task of additional insulation is not set, but only to protect the front surface of the external walls, then insulation is not used. But this is the exception rather than the rule.
In the vast majority of cases, when installing a ventilated facade system, thermal insulation material is installed.
Theoretically, any insulation can be installed under a ventilated façade. But the main requirement that is put forward to the insulator is that it can ensure the passage of steam from the room. Traditional rigid insulation materials, such as polystyrene foam or expanded polystyrene, do not meet this requirement (especially in case of fire, they emit harmful substance- styrene). Therefore, preference is usually given to soft insulation materials - basalt wool, less often glass wool.
Note. An excellent solution for use in a ventilation facade system is to install double-density mineral wool. Such a material, on the one hand, has sufficient vapor permeability, and on the other, the necessary reserve of rigidity.
An example is the products of Rockwool (Russia, Poland or Denmark). Stone wool slabs Venti Butts D (two-layer insulation) have a density of 90/45 kg/m3 (90 for the top layer, 45 for the bottom), and Facade Butts D Optima - 180/94. The cost of Venti Butts D (100 mm) starts from 2,283 rubles/m3, the cost of Facade Butts D Optima from 2,205 rubles/m3.
Among other advantages basalt wool can be attributed: non-flammability, stability of shape, ease of installation, resistance to wind, immunity to biological factors.
The use of steam-, hydro- and wind-proof films makes it possible to additionally protect the insulation from the effects of moisture contained in the air moving between the facing material and the wall, as well as from wind pressure. Wind barrier film is rarely used today, because... it was replaced by new progressive materials - superdiffusion membrane and geotextiles.
The membrane is a synthetic semi-permeable film that can regulate diffusion properties.
Geotextiles (construction) is a synthetic fabric made of polypropylene (less commonly polyester), which reliably protects the insulation from destruction. In addition, it is resistant to high and low temperatures, the influence of chemicals, is tear-resistant and is a serious barrier to various living creatures and bacteria.
A distinctive feature of these materials is one-sided vapor permeability. On the one hand, they effectively remove steam that leaves the room through the insulation, thus preventing it from getting wet. On the other hand, they protect against moisture from the outside (precipitation).
Also positive reviews about geotextiles
The maximum vapor permeability for the membrane is > 1200 g/m2/24 hours.
The air gap gives the ventilation façade the properties of a thermos and protects the house from significant temperature fluctuations. Thanks to the air, the building cools down more slowly in winter and heats up in summer.
Advice. For the effective and durable functioning of a ventilation façade, conditions must be provided - the air moving in the curtain wall system must overcome some resistance created by the flangings of metal cassettes or slabs.
As a rule, the gap size is 40-60 mm, up to 100 mm, but the minimum-maximum size is calculated for each case individually.
If the gap is too small, the heat-insulating layer may be destroyed (when the insulation is adjacent to the cladding). As a result, the surface of the wall will get wet and collapse.
If the gap is too large, a hum (noise) may appear in strong directional wind. This happens when wrong choice the length of the brackets, as well as when using low-hardness wool as insulation.
The decorative layer of cladding is the visible part of the ventilation facade. Today there are more than two dozen varieties finishing materials for cladding a ventilated façade, which can be combined into six groups:
Note. Installation of materials such as porcelain stoneware, cassette and linear panels is possible only using factory metal frame, because They are distinguished by the presence of guides and factory fastenings.
Due to the variety of facing materials, the customer has the opportunity to implement any design solution.
Comparison of advantages and disadvantages according to a number of parameters.
Due to their advantages and despite their disadvantages, ventilated facades are gradually replacing traditional methods of finishing buildings.
Both the new building and the old house need to create a barrier to external destructive factors, which significantly reduce the service life of the supporting structure.
IN Lately the owners are trying to make a ventilated façade with their own hands. This design is such a barrier, and the installation process is so simple that even a beginner can do everything on their own.
A ventilated facade is a suspended structure that consists of a sheathing (frame), vapor-tight membranes, insulation and facing material. This kind of “pie” perfectly performs its functions and has the following advantages:
Features of the ventilation façade
All these positive characteristics and allowed ventilated facades to become so popular. But each material or finishing method also has some disadvantages:
The frame in the design of a ventilated facade is the main element. Both the insulation and decorative coating. Therefore, it is very important to choose high-quality materials for creating the sheathing. The frame can be made from:
Wood is a cheaper material. But it is used extremely rarely for ventilated facades. The bars must be thoroughly dried and coated with special protective impregnations to extend their service life. It is important that all elements are the same size 20x20 mm.
Professionals recommend using a galvanized or stainless steel profile to build a ventilated facade with your own hands. This material is lightweight, reliable and has a long service life without special treatment. With the help of special profiles it is much easier to hide uneven walls, if any, without plastering.
As mentioned above, the steam that forms in the premises must be removed by any means. Most often, ventilation is installed for this, but some of it escapes through pores in the walls. To prevent moisture from accumulating in the insulation, it is protected with a vapor-proof membrane from the wall of the house.
But the same layer is applied on top of the insulating material. This is necessary in order to cold air did not have the opportunity to penetrate to the load-bearing wall, and therefore cool it. This membrane is also called windproof.
As a decorative finish, you can choose absolutely any option you like. The main thing is that the main structure, that is, the walls of the house and the foundation, can withstand such a load.
Often chosen as cladding:
To make a ventilated facade with your own hands, you need to know the main steps, as well as some features and nuances. If you are doing everything for the first time, then it is better to invite a professional craftsman and be his apprentice, this will significantly reduce the cost of the work. It is also better to prepare the facade in advance.
In order for the ventilation façade to perform its functions, the base must be properly prepared.
On preparatory stage everything should be purchased necessary materials and get some tools.
Making a ventilated façade yourself is easy. The main thing is to remember the instructions and strictly follow their advice:
Attention! If the house is made of light, porous materials, fasteners should be installed in the interfloor ceilings.
If you strictly follow these instructions, your self-installed ventilated façade will last a very long time. Well, of course, you need to correctly calculate your strength. If you are not sure, then it is better to use the services of a professional team.
Our qualified team will assemble the facade system according to the drawings of our own design bureau. We have a powerful production facility for processing natural stone, which is equipped with modern equipment.
NVF is a multilayer structure consisting of thermal insulation, subsystem elements and façade cladding material. Allows you to keep the load-bearing wall in a dry state, which prevents the accumulation of condensation and moisture, reduces heat loss - the ventilation gap between the facing material and the insulation allows you to retain heat in the house and creates a kind of ventilation.

PurposeHinged ventilated facades insulate the building and give it an excellent appearance. This system is suitable for any type of premises:
It is the ideal solution if you do not want to repair the facade every few years or want to replace the outdated and damaged appearance of the building. They will help not only improve the appearance, hide defects, but also insulate the building, saving on energy. |

Any work on a ventilation facade begins with an idea with which the customer comes to the company. This can be a drawing, a schematic sketch, a project or a 3D visualization, which at the first stage will help create general ideas about the future project. The feasibility of 3D visualization is obvious. After all, the picture will display ideas about color and style not “on the fingers,” but clearly and from different angles. Here Special attention it is worth paying attention to the wishes of the customer, which must also meet general aesthetic ideas. That's why this type The service is very complex and painstaking, which increases the value of the design project.
After agreeing on the visual image of the future object, work on the design project begins. A working group is created, led by the lead architect of the project, consisting of a chief designer, a technologist for the production of stone products, a construction technologist, and an estimator.
A team of qualified specialists studies design and circuit solutions, prepares design documents for a preliminary design in accordance with GOST 2.118-73, which must necessarily include general view drawing with dimensions, sections, technical characteristics of the product, preliminary design sheet And explanatory note taking into account the requirements according to GOST 2.106-96.

“Working on documents based on a preliminary design is very specific and complex, which only a competent employee can do. Moreover, when it comes to ventilated facades. Our company provides all services comprehensively, which is very convenient and frees the customer from many hassles. From experience I can say that it is at the stage of a preliminary design that a client who turns to non-specialized companies, due to ignorance of many subtleties, lacks full package documents for illegal armed groups that comply with GOST. This often causes significant additional expenses. “YarKamen, in turn, is ready to build a ventilated facade on a turnkey basis with responsibility for all stages of work on the project,” comments the project manager of the YarKamen company. Artem Noskov. |
And let knowledge become key requirement in this subsection, because only a professional will take responsibility for working on the working documentation, draw it up in the required form in accordance with GOST requirements and guarantee that everything is done correctly. Otherwise…
Risks: if a client comes to our company with his project, it will still be reviewed, analyzed, and checked. From experience, in projects that are not carried out by specialized organizations, many mistakes are made. For processing, the customer will overpay approximately 3% and add 10% of working time. Thus, the total cost of the facade will increase both in the total amount and in terms of time.
But that is not all. A working group led by a leading architect is working on the architectural elements of the facade in accordance with the geometric features of the walls. The possibilities of manufacturing façade parts are also taken into account based on the production capabilities of the facility as a whole. An important issue in preparing a preliminary design is the choice of material. This is where the price is essentially determined. Remember that the cheapest and most suitable color does not always provide the necessary durability.
The YarKamen company is ready to recommend the most suitable materials for the external cladding of the building, as well as organize prompt delivery from the best deposits of natural stone, taking into account the technical characteristics of the raw materials and, most importantly, the price issue. An established logistics scheme has allowed us to supply stone for the past 15 years, freeing the client from all customs hassles. Otherwise…
Risks: Organizing the production of stone parts in another contracting organization for the purpose of saving does not guarantee you an objectively affordable cost. But the absence special knowledge in area facade cladding made of stone and low quality guaranteed. Everything that the client takes upon himself is his personal responsibility. If unsuccessful, you may incur significant costs. More precisely, the production of new parts with the delivery of stone will cost about 30%. Of course, the percentage ratio was chosen based on the standard simple design of a ventilated facade. But here, too, plus 33% (taking into account the reworking of the project, which was written about above) to the total cost for the customer - a lot of money!
Natural stone is a rather specific material, which is characterized by instability of color, texture and structure. In addition, not every stone is suitable for our climatic conditions. When choosing a material for a facade, you need to take into account its porosity, water absorption, and frost resistance.
The facade, in turn, protects the building from the aggressive environment - rain, snow, sun, wind. The stone used must withstand all these natural phenomena.
It is no secret that precipitation has a detrimental effect on the condition building materials- as a result of water absorption, destructive processes begin. It is also known that when making products in production, the stone is constantly in water. All moisture that it manages to absorb during the production process using technology must be removed. So, to increase the durability of the material and its subsequent proper operation, some types of stone undergo a process of hydrophobization - a special treatment of the stone against moisture penetration. Hydrophobization of stone extends the life of the material for many years. It is performed using volumetric or surface application of a special impregnation to the surface - a water repellent, which penetrates deep into the structure to a depth of 5-20 mm. A crust forms on the hard base of the stone, repelling water. In this case, the pores are not clogged, the air exchange of the walls is not disturbed.
In particular, travertine, limestone, which are often used in facade finishing, tend to absorb moisture. But before the stone undergoes the hydrophobization process, the material must be thoroughly dried and prepared for subsequent processing. Under natural conditions, the process of moisture evaporation takes a very long time. But we took care of it! "YarKamen" developed special technology volumetric drying of stone. The chamber creates ideal conditions for removing moisture and is able to operate at any time of the year, even in the harshest conditions.
Risks: Without special drying, moisture inside the material will lead to premature destruction of stone with low frost resistance. In particular, in winter, if the stone has not undergone additional drying, but has been subjected to a hydrophobization process, prepare for significant repeated costs. Conclusion: trust the professionals. The YarKamen company optimizes the project to ensure maximum durability while maintaining the architectural design. Therefore, when developing a preliminary design, you need to be not only competent in the stone industry, but also objectively assess your capabilities.
The result of numerous works, negotiations, approvals is a finished preliminary design, optimized taking into account the characteristics of the materials used, the design characteristics of the building and walls. When developing a project, requirements for materials must be drawn up, the main issues of manufacturing technology must be worked out, and optimal options products and parts in accordance with the requirements of the facility, a competent assessment of products was carried out in accordance with the requirements of ergonomics and technical aesthetics, solutions were developed to ensure the reliability of the material, and a preliminary decision was made on the packaging and transportation of the stone.
An important point is the choice of subsystem and components. YarKamen works with trusted subsystem suppliers. And when helping to select illegal armed groups systems, we take into account architectural features facade. The amount and type of these materials may vary depending on the cladding material and the area of the cladding slab.
Risks: There are cases when a customer comes with an already purchased subsystem. And as a result, it is either not enough or it does not fit. Here it should be borne in mind that work on the facade must be thought out to the smallest detail. After all, if the calculation of the subsystem was initially made incorrectly or the architectural features of the facade were not taken into account thoroughly, the probability of encountering unforeseen expenses is 100%.
Think before you get ahead of things... After all, your personal liability risks adding about 10% to the total cost of the project. And this is just a subsystem...
So, the most responsible and scrupulous stage of creating working documentation. It includes several sub-steps that are related to each other.
Based architectural project Our team of surveyors carries out an on-site survey of the property. It is this that will form the basis of the future project, which will determine in detail every step of many subsequent works. Carrying out a project using competent geodesy makes it possible to more accurately “link” architectural cladding elements and subsystem elements.
Risks: Coming to a company with geodetic surveys from contractors is a big risk. Since the company is not responsible for the quality of the information provided, which will form the basis for detailing the object. If you make mistakes in the early stages, you may encounter unexpected serious problems in all further work: from design to installation. And when you are happy that the work on producing the project seems to have begun successfully, we will prepare a conclusion on the consequences of incorrect measurements and draw up an estimate for repeated types of work. Superfluous, isn't it?

Next comes the development of fundamental fastening units for the subsystem, production wiring diagrams and detail drawings for cutting cladding elements, taking into account the specifics of fastening, dimensions and position of the slabs on the facade... All this will form the basis for a consolidated specification of system and additional components indicating the articles, sizes, quantities and colors of the stone. The project developed by the YarKamnya design bureau will also become the foundation for creating parts from the selected material in production.
Risks: Mistakes made in the project will certainly lead to serious discrepancies when installing the stone on site. And this is a whole series of additional expenses, the responsibility for which, as well as for errors, is borne by the customer himself. In the case of parallel work between a designer from one company and an architect from another, an active issue of communication arises. When errors are identified, it is very easy to find the culprit. You can also determine who is slowing down the project. But are you interested in increasing the project completion time?!

"We encountered different situations. But when we receive drawings from a customer made by a contractor, we revise them in any case. And, as it turns out, not in vain. In all cases we find inaccuracies, gross mistakes and we are trying to convey to the customer the idea that there is no need to run to different authorities for a project, this does not lead to anything good. Along with errors in the working documentation, the customer brings with him hundreds of communication issues that we have to deal with contractors. This is a big disadvantage than the long-developed scheme in your team. A suspended ventilated façade is a complex system. And when signing another project for work, I personally feel responsible for every pebble that will hang on the wall and that it must hang correctly, otherwise it’s scary to imagine... Therefore, trust your idea exclusively to experienced specialists!” - emphasizes the leading designer of the YarKamen company Yulia Vakulenko. |
In parallel with the preparation of working documentation, YarKamny designers are developing stone detailing. In what sizes it will be made and how the products will be produced is determined by the documentation on detailing the natural stone, taking into account the wishes of the customer and the individual characteristics of the material.
Next, the supply of the selected stone begins, followed by the production of facade elements according to the developed working documentation. At the YarKamen company, manufacturing work is carried out at our own powerful complex, which we continue to be proud of. This speeds up the process of completing an object and allows the customer to track the production process at any stage. Parts are manufactured according to approved sketches and on time.
Risks: If mistakes were made in the project at the early stages or you ordered a stone from another contractor, then you are responsible for the size, fit of parts, as well as the quality of their calibration. The amount of your personal responsibility for the result of the work may be equal to an additional 30% for the re-production of facade parts.
|
After detailing the stone, installation of the subsystem on the facade begins according to the working documentation. This stage follows and is interconnected with the previous one.
Risks: The most common mistake among clients is to independently purchase a subsystem from a company to which it is important to sell without specifying the following professional details: the capabilities of the subsystem by weight category (selected individually for each stone).
.jpg)
After going through many stage-by-stage work, the YarKamen company begins installation of products on site. Many years of experience and scrupulousness at each stage of the project will result in a high-quality curtain wall that meets all the wishes and ideas of the customer, as well as GOST requirements, taking into account quality and safety.
Risks: Obviously, by resorting to an independent search for contractors to create working documentation, supply stone, and manufacture parts, the customer runs the risk of encountering discrepancies at the end when joining parts on site. And such deviations in the project are fraught with very serious proceedings - one, additional costs - two. Easier to create new project, but the only right decision remains to work with a competent company from the very beginning, which YarKamen has been with for more than 15 years.
And there are many such stories. Having received the final figure for the turnkey project, the customer decides to save money and entrusts each stage to completely different contractors. As a result, the result leaves much to be desired.
We talked about typical mistakes customers who think that they can save money if they independently begin to implement the project of a suspended ventilated facade. Among them are an incorrectly prepared preliminary design, gross errors in drawings, violation of delivery deadlines for materials, and non-compliance with production technologies. All this and much more will result from creating a low-quality facade. It will also have a significant impact on the budget. The additional costs that the client risks incurring in the process of work will, of course, negatively affect his overall moral and financial condition.
We bring to your attention a summary table of costs, which depend on the stage at which you decide to involve specialists.
| "Full construction" | Stage 1 | Stage 2 | Stage 3 | Stage 4 | Deadlines | |
| Project | 5% | 3% | 3% | 3% | 3% | 10% |
| Stone details | 60% | 0% | 30% | 30% | 30% | 30% |
| Subsystem | > 20% | 0% | 0% | 10% | 10% | 10% |
| Installation | 15% | 0% | 0% | 0% | 25% | 60% |
| Total | 100% | 0% | +33% | +43% | +68% | 100% |
| Taking into account overpayments: | 103% | 133% | 143% | 168% |
The table shows what percentage of the total amount increases sharply if you do not initially contact a non-specialized company.
With this material we emphasize that only experience and extensive practice will help create a high-quality facade taking into account the requirements of GOST, safety and ergonomics.
