Wet facade Mounting technology. Wet facade - wall decoration for conscience

Warring your home, the indental owner always prefers the walls of the walls with the outer arrangement of the insulation. Although the performance of work on the inner surface of the walls is easier and costs cheaper, but a serious homeowner is known for at least three main arguments in favor of an outdoor solution.

Why choose the outdoor arrangement of the insulation:

• location "Dew points" (condensate falling zones) when the temperature drops inside and outside the house. If the insulation is on the inner surface of the carrier wall, the constant condensate loss makes it wet. Such a phenomenon is sharp reduces functionality The used thermal insulation - it loses the properties of thermal protection, the house becomes raw, the fungal mold appears, etc.;
• the level of thermal inertia (Heat Resistance) walls with outdoor insulation is much higher. Simply put, the house, insulated outside, cools much slower when the outdoor temperature is reduced;
• outdoor thermal insulation Guaranteed overlaps all the available "cold bridges" in the house design, which are the main ways of heat loss.

Existing types of external facade systems are divided two big groupswho received the names of "dry" and "wet." The first group of "dry facades" is called still nationally or mounted. An example of such systems can serve as facades from vinyl or metal siding. Thanks high practical efficiency, efficiency and decorative opportunities, the "wet" insulation technologies called "wet facade" are very popular in the entire civilized world.

What is the "Wet Facade" system?

"Wet" technologies of the device of warmed facades are based on the creation on the outer surface of the bearing walls of peculiar Multilayer fortified cake.During the work, special adhesives, mastic and plaster are applied, as a rule, posted on ordinary water.

The technique of "wet" installation includes applying in strict odds The layers of the primer base, adhesive composition, gluing and additional strengthening with special means of a layer of heat-insulating material, creating a reinforcing layer with a special grid, which is performed by several layers carrying protective and decorative functions. As a result, it is formed one system, Possessing a number of indisputable advantages:

• allows you to provide special decorativeness and attractiveness, no salt spots on the outer walls, originally having a rough surface of any quality;
• high efficiency I. small weight design thermal fence does not require a powerful bearing foundation, as a rule, a significant part of the total cost of building houses;
• the outer thermal insulation of the carrier wall allows, as in the thermos, save and to accumulate heat in the house, completely blocking numerous "cold bridges";
• ruled out The formation of condensate on the inner surface of the walls and their wetting - the "dew point" is carried out beyond the wall structure in the insulation material, from which the exterior layers of plaster evaporates through "breathable";
• the construction material of the house is reliably protected from the destructive impact of moisture - it is excluded by its freezing in the microcracks of concrete structures and corrosion of frame fittings;
• "Wet" facade gives outdoor walls additional Vibro- and sound insulation.

Practical and efficient "wet" technology turns out cheaper in implementation And everywhere apply not only during the finishing works of industrial buildings, but also in private and low-rise construction. However, the listed advantages pleased the owners of the house, it is necessary to strictly adhere to Technology requirements, the choice of relevant quality materials. One of the important features is the time of work. There are certain limitations of the outer air temperature associated with the properties of the materials used.

All plastering operations, coloring and other "wet" finish finish phases can be performed at temperatures. not less +5 degrees Celsius. From how far exactly the fulfillment of all the conditions will depend on the quality of the work, and the service life of the finished facade. Disturbance of the temperature regime, the use of materials that are not intended for the "wet" facade device can lead to cracking and even to showered the outer layer.

The cost of arrangement of the wet facade

The cost of the device of the facades using "wet" technician turns out noticeably lowerhinged ventilated facades requiring, in addition to the high cost of materials, additional expenses for the remuneration of installation of installers having high qualifications. And in this case, as a rule, the value of the installation itself is from 30 to 50 percentfrom the amount of total expenditures on the ventilated facade. In addition, it is necessary to take into account certain difficulties in the search for truly qualified specialists, for example, to carry out the installation of a ventilated facade of natural stone.

If the cost of only facing material (stone) begins from several thousand rubles per square, then the choice of unskilled personnel is fraught with loss of significant funds. It is easy to compare the real cost of finishing the outer walls of the house for "wet" and various attached technologies by viewing price offers for all options from construction companies. Data on the network sites confirm the output about high economyand the optimal ratio of "price-quality" of the "wet" facade technology. His real price is approximately 76 - 18 percent From the amounts necessary for performing facades from fibrotent plates, aluminum composite panels, porcelain stoneware, metal cassette or natural stone. It is necessary to consider that the "wet" facade, performed by its own hands, will cost even cheaper.

Physico-chemical characteristics of the insulation for the "wet" facade

Arranged on the outer surface of the carrier wall, according to the technology of "wet" facade, thermal insulation system Consists of three main parts:

• layer of thermal insulation, strengthened on the ground base with the help of glue and special plastic dowels;
• the layer of the reinforced base, performed on the basis of alkali-resistant fastener and mineral glue of the special composition;
• the finishing layer, which includes primer and special plaster on a polymer, mineral or siloxane basis.

It is difficult to allocate more important part of the three listed. The right choice of each determines the effectiveness of the entire system. Outer layer of finishing Performs a two-way role, being aesthetically defining the "face" of the entire layer of finishing and, at the same time, reliably protecting the heat insulator from an adverse external influence. In addition, the layer should be well to pass the evaporation of moisture condensed in the material of the thermal insulator.

Reinforced base It is necessary for reliable fastening at the level of the adhesion of the finish layer. And there will be a special, resistant alkalis, grid. As a rule, it is a material based on fiberglass with a special coating. It is installed on a special glue, completely bleak into it. If you apply the usual grid, without processing, about a year after its reinforcing frame, there will be nothing left, and the top layer, the important function of which is already mentioned, it will simply be deached.

Layer of thermal insulationrequires the use of appropriate materials. Its thickness is calculated by heat engineering, and the species is determined by the use and requirements of fire safety. The most common and traditional materials are:

• fibrous: cotton wools from mineral and fiberglass, the fibers of which are obtained by stretching from the melts of natural: stone mineral raw materials, waste of metallurgical production and glass mass;
• foamed gas-filled plasticswith a cellular structure - foam plastics, of which expanded polystyrene foam;
• arbolites (lung concretes) Based on waste recycling, flax, hemp, etc., Portland cement and natural hardener.

An important parameter of all thermal insulation materials (TIM) is their density. For fibrous Tim, the density should be at least 150-180 kilograms per cubic meter. Mineral wool Preferably for finishing facades. They are more durable, not combustible, they differ in good sound insulation. Experts recommend using wats on phenolicbinders like more waterproof. Since in addition to the density, the absorption indicator of moisture is important for Tim. This parameter must be no more than 15%. Among other advantages of stone wat resistance to chemical and biological substances, environmental purity, low weight and lightness of installation.

Glass wool, due to longer fibers, have a greater indicator of elasticity. They also have high strength. But the heat resistance of the material is significantly lower and does not exceed 450 degrees Celsius.

Extremely common different polystyrene foam, for example, brands of PSB-35, PPSB-s. They are less resistant to elevated temperatures and already at 100 degrees begin to melt and swell. With long and constant exposure to sunlight, yellow and crumbling. However, new modifications appear with increased resistance to sunlight and temperatures.

Also gaining popularity New ecological material Arbolit. He refers to the category of light concrete. It has about 90% of natural fillers: flax campfire and hemp, wood sawdust, husk, etc., Portland cement and natural hardener. The density of arbolite for thermal insulation is from 400 to 500kilogram per cubic meter.

Depending on the type of heater used, the corresponding glue composition is used. For example, glue on a bitumen basis is often used for polystyrene plates.

Mounting technology "Wet" facade

One of the options for the implementation of the "wet" facade can be an approximate step-by-step description of the procedure for following the steps of work. The beginning of all works must be preceded by thorough preparation, including ratue rating and device, on which, layer behind the layer, the entire finishing "Pie" will be applied.

Preparatory operations for the installation of a wet facade:

• the outer surface of the walls is cleaned of all types of dirt and residues of old coatings;
• to improve the bearing ability, is carried out chernovo plastering, alignment and strengthening damage and cracks;
• the slopes of window and door openings are cleaned from the old plaster;
• to obtain the required adhesionThe surface is pretty nevertheless.

Mandatory operation is device support plank. With its lower edge, the entire insulation system relies on a special P-shaped profile, called "reference base". With its markup and fastening around the perimeter of the house, all work on the direct installation of the "wet" facade begins. The profile performs several important functions:

• is the basis for the weight distribution of the entire set of layers;
• protects the lower edge of the set from the exposure of moisture.

The support base is attached at an altitude of 40 centimeters from zero level (from the Earth). To account for temperature expansion, between its horizontal planks is necessarily left gap0.3 centimeters. Self-tapes and dowels are used in the profile fastening technology. The amount on the pattern meter depends on the total estimated weight of the facade layer in height. At least 5-10 points, i.e., the fastening step ranges from 10 to 20 centimeters. The corners of the base reference bar are performed from special angular profile.

After that, work is moving to the fastening stage the layer of thermal isolation.Most often, the plates of mineral wool or polystyrene foam are first pasted on the prepared outer surface of the bearing walls. The method of application of glue, which allows simultaneously to ensure the strength of the mount and the economical consumption of composition, provides for the application of a wide band around the perimeter plate In a pair of troika centimeters from the edge and point plots. The sufficiency criterion serves as a rule that should be covered with adhesive at least 40% of the insulation area. The exception is the lamella mats, their inner side is covered with glue completely.

Plate installation rules

Installation of plates, ranging from the bottom row based on the base profile, is performed according to the rules:

• the seams between the plates in the adjacent rows should be overlapped, the solid vertical seams in the height of several rows are not allowed;
• with a sticker, the base plate is tightly pressed to the base, and the end, with a minimum gap, to the adjacent plate of the glued row. It is necessary to strive to minimize the thickness of the seams;
• prix \u200b\u200bprotruding from seams is immediately removed.

For additional strengthening of the insulation slab material, after three days after drying the adhesive composition, setting plastic dowelsspecial design. Their sizes are determined by the thickness and material of the insulation, and the design includes a plate of a plate-type and a plastic nail separating a dowel. The right choice of dowels takes into account that the depth of the hole for porous Tim is not less than 5 cm, And for solid - 9 cm. The rate of consumption per square meter depends on the mass (thickness) of the insulation and is usually from 6 to 14 pieces.

The order of attachment by dowels:

• symmetrically and evenly, by pre-performed marking of the area of \u200b\u200bthe panel, the required number of holes are drilled into the required depth;
• the material is performed at the dowel;
• flush parts are placed;
• carefully clog off the sawing plastic nails.

The reinforcement phase begins no earlier than 1 - 3 days After the final fastening of the heat insulation layer. This stage includes:

• processing of the angles of window and door openings, joints and horizontal jumpers, exterior angles, for which a special corner profile is used;
• the insulation material is covered with adhesive composition, a layer thickness from 2 to 3 millimeters;
• the construction grid of fiberglass (necessarily a special alkaline coating) is combined in the adhesive layer;
• a glue composition is applied, a layer of up to 2 millimeters, from the calculation of the total thickness of the entire reinforcement to 6 millimeters.

Finish finish It is the final phase of the "wet" facade device and begins not earlier than the final drying of the reinforcing layer. This may be required from 3 to 7 days. Finish finish includes applying plaster on a layer of reinforcement. The following requirements are presented to its properties:

• high permeability for steam;
• resistance to external moisture and other climatic factors;
• mechanical strength.

To do this is used Special compositionsfor outdoor work. In addition, the decisive factor in the qualitative performance of work is becoming compliance with the temperature requirements: the worker is considered the range from +5 to +30 degrees Celsius. The protection of the applied layer from the direct fall of sun rays is required.

The supporting structures of buildings do not carry the tasks to ensure sufficient thermal protection of the premises. Brick, slagoblock, wood, reinforced concrete panels or monolithic fence elements do not withstand requirements for this parameter. Therefore, they need additional processing insulation.

This is one of the methods of lightweight insulation, which allows:

1. Add additional thermal protection to wall panels.
2. Increase the heat saving of the premises.
3. Give an attractive appearance to the building.

The fundamental system of the Wet insulation device using the "Wet Facade" technology

The outer decorative layer is the plaster, thanks to which the facades acquire attractiveness. The insulation of the facades is wet involved in the use of thermal insulation. The list of layers of the system from the inner to the outer looks like this:

• actually wall;
• glue composition;
• insulation;
• reinforced starting plaster layer;
• decorative finishing plaster for outdoor work.

The main advantage of the technology is that wet facade can be mounted in any climatic zones. Minus - work should be made at ambient temperature at least +5 0 C and no more than +30 0.

In the cold period, the place of work should be heated and hidden from the environment by the Shatter. The wet facade This technology is referred to because binding substances are binding to water and at the time of application are wet.

What insulation are used in the wet facade systems?

Glasswater and minvat are categorically prohibited. It is associated with insufficient strength of these insulation. They are not able to withstand a lot of plaster. In view of this, they are prone to resolving. Polyfoam is also not included in the number of thermally insulation.

Typical insulation for wet facade - polystyrene foam and basalt wool

By mounting the wet facade with your own hands, involuntarily asked the question "What thickness should the insulation?" The building market is represented by a wide range of basalt wool in various thickness (from 2.5 to 20 cm). Among the proposed need to choose the one that will fully satisfy the requirements. If there is a project available, then in it this parameter must be specified.

If the work is performed without project documentation, then the climatic conditions of the region must be taken into account. The indicator of the total heat transfer parameter can be found in reference books. The help of a climate map of the Russian Federation, which is easy to find on the Internet.

It is necessary to compare the resistance indicators of the heat transfer material of the wall panels with the specified numbers on the map. The difference must be compensated for insulation. When calculating, it is necessary to consider and the characteristic of the outer plaster. Too overestimate the indicators of the warmed structure is not worth it. The balance of humidity and temperature must be respected.

What else will required in addition to the insulation?

The full list of necessary materials is as follows:

• glue for fastening the insulation to the wall;
• aluminum profile;
• dowels for fastening profile;
• plastic dowels for fixing the insulation;
• insulation;
• primer;
• plastering arms;
• dowels for fastening insulation and arms (plastic);
• starting plaster (basic);
• finish decorative plaster.

Tool kit for a wet facade device

In addition, devices will be required:

• perforator (for concrete, brick, reinforced concrete panels);
• drill (for wooden walls);
• screwdriver (for screwing the dowels);
• special spatula for applying glue;
• set of spatulas for overlaying and smuggling plaster;
• containers for mixing construction mixtures;
• nozzle on a drill for mixing;
• brushes for stripping a wall surface before applying glue.

It is possible to perform the work on its own, but for this it requires elementary construction skills and a technological map to the device of a warmed facade on the "wet method". This is especially true of plastering.

Work on insulation wet facade gradually

Step-by-step instructions of the wet facade technology looks like this:

1. Preparation of the wall surface.

   

   Grinding of insulated walls - an important stage of surface preparation

   This procedure involves cleaning the surface from any existing contaminants. In addition, it is necessary that it be smooth. The maximum drop on 1 m 2 area should not exceed 1 cm. Orthodox, shells should be aligned with plaster. If the wall has places with swept fragments, you need to use the fastening soil. Primary preferably the entire surface. This will serve for the wall of additional protection.

2. Installing the base profile.

   

   It will perform two functions: levels and node taking the load of the upper plates of the insulation.

3. Applying glue.

   

   This procedure is performed by a special gear spatula. The adhesive composition is applied on the plates of the insulation, not on the wall.

4. Gluing.

   

   The procedure is performed from the bottom up belts. Plates located above the base profile must rely on it. When the door and window openings are saved, the plates must be glued so that the opening angles are located within one solid slab. For this, there are special cuts in the insulation.

5. Fastening the insulation plates with plastic dowels with a wide hat.

   

   Work is performed after complete drying of the glue.

6. Apply the base plaster layer, 3-5 mm thick.

   

   The key stage of the wet facade - applying a plastering layer with reinforcement

7. Laying the reinforced grid. Work is performed before setting plaster. It is important that the grid is recessed into the plaster layer.
8. Alignment finish plaster.
9. Painting.

   

   Finishing Stage Finishing - Surface Coloring

Armed with knowledge, materials and necessary technical Inventory can be started at the installation of a wet facade.

Heavy and Light Wet Facades

There are two varieties of wet facades:

Heavy wet facade is used in seismic union zones, as well as in cases where thermal deformations occurring during the temperature differences are required. Thanks to constructive features, the plaster remains holistic (not cracking).

But there are cons. Such is high compared to the light facade cost. It is associated with the fact that the amount of consumed plaster may increase at times, since its thickness of its layer can reach 20-40 mm. The army also pulls the rise in price, because it must be metallic, unlike a light wet facade, where polymer materials are used.

Another minus is a big weight. If the building is dilapidated and subject to reconstruction, the use of a heavy facade without special strength calculations may result in collapse. For most cases, a lightweight system is suitable. Moreover, companies are now present on the market, which can comply with high-quality materials.

Wet Facade Cerezite - Popular System

Brand Mark Cerezit has developed a complex of products for mounting facades on the technology of wet. The complex includes all components of the insulating cake:

• glue;
• military insulators based on Minvati or polystyrene foam;
• plastering mixes.

Those who decide to take advantage of the unified system of the wet facade of Cerezite, do not have to check the components of incompatibility. All components were developed with a loan to this parameter. Moreover, each component complements the functions of another and compensates for its disadvantages.

Let's sum up

Based on the above, it can be seen that the technology of the wet facade remains the most reliable and best way to insulate the building. Having a description of the necessary actions, everyone can independently perform work and make the house warm, cozy and beautiful outwardly.

Some people confuse the name "wet facade". In fact, this is the generalized name of all methods in which semi-liquid or liquid glue solutions are used for fastening the insulation, reinforcement grid or facing material.

For the first time, this technology was applied in Germany in the 60s - 70s of the last century, when the question of increasing. It must be said that it is the external insulation of the walls that is the most correct, as it allows you to make the "dew point" beyond the inner beds, shifting it outwards.

Therefore, even with a large difference in the inner and external temperature on the inner surfaces of the walls, condensate is not formed.

What is a wet facade

Wet facade is a whole system consisting of several layers of specially selected materials. Moreover, they choose them so that their main physical characteristics are similar to them - water absorption, thermal expansion, vapor permeability, frost resistance.

The device of an efficient wet facade requires compliance with two mandatory conditions:
• the thermal circuit should be continuous, that is, without cracks, pass and breaks;

• the whole "puff pastry" of the facade should be vapor-permeable (therefore, the materials are selected so that each subsequent layer in the direction of from the inside - to the outside had vapor permeability greater than the previous one), then the house will "breathe"

All facade pie consists of the following layers:
• The glue layer is the first layer consisting of a glue mixture. It is very important, since the density of the insulation of the insulation to the wall depends on its quality.
• The heat-insulating layer - with a low thermal conductivity (most often used polystyrene and mineral wool). The thickness of this layer is determined by the heat engineering, based on the properties of the material and the operating conditions. It is very important that the material is fireproof.
• The reinforced layer consisting of glue of mineral composition and alkaline reinforcing mesh. It serves to better clutch the surface of the insulation and plaster layer.
• The protective layer (decorative) is a primer and a layer that protects the insulation from external influences, and is also a finishing layer.

All materials used for the wet facade must have a certificate of conformity of the accredited center, and the insulation system as a whole is a technical certificate of the state sample.

Preparation for installation of the system wet facade

To work, it is best to choose a period when the temperature does not exceed +10 - 200 ° C, the weather is dry. There are forests with a protective grid, which protects it from moisture and sunlight.

If it is necessary to perform work in the cold season, then the heat is created around the building, providing the temperature +5 - 100.

Before starting the installation of the system, the facade should be prepared:
• the walls are cleaned of old laying plaster, paint and any contamination (dirt, soot, dust, rust);
• the surface is ground, surface defects are aligned with cement mixture. If the surface is porous, the primer is applied to 2 to 3 layers.

Before the start of work, it is necessary to establish a base profile whose task is to align the facade horizontally and protect the insulation from external influences. The profile is installed at an altitude of about 0.4 m from the soil level, attached to the wall with dowels and self-drawing with a step of 10 - 20 cm.

Between the profile straps leave the gap of about 3 mm, which is necessary for their temperature expansion.

Prior to work, the following conditions must be completed, guaranteeing the absence of excessive humidity in the structures of the structure:
• completed installation of the roof of the building;
• mounted;
• installed ventilation systems and;

• windows are installed;
• completed all concrete work, fill and floors of floors;
• the primary wall decoration inside the building is completed;
• the building is well succumbed and its full shrinkage occurred.

Installation sequence and technology

The insulation plate fastening is made with glue.

At the same time, the following rules must be followed:
• the glue is applied with a wide band around the perimeter of the plate, retreating from the edge of about 3 cm;
• on the middle of the plate, the glue is applied point in such a quantity so that in the end it was covered by at least 40% of the plates area;
• the insulation fastening is made by rows, bottom-up, ranging from the base profile. The plates are glued into the disintegration, tightly pressing them to the wall and to each other. Excess glue must be immediately removed.
• when it is completely dry (and this will happen about 3 days), the insulation will additionally be fixed with spacer dowels at the rate of 6 -14 dowels per square meter of the wall. The amount depends on the mass and thickness of the insulation. If the wall material is solid, the dowel is enough to deepen into the wall by 5 cm, if the porous, then 9 cm;
• before installing a dowel, you need to prepare a nest for it. Clamping sleeves should be flush to the surface of the insulation plates.

The works on the device of the reinforcing layer are proceeded in 2 - 3 days after the installation of thermal insulation. First, the window and door corner squeaks are reinforced, the outer corners of the building, and the remaining plane of the walls last.

Works are performed as follows:
• directly on the surface of the insulation, a special glue composition is applied and then the grid of fiberglass is interinted. The recess of the grid cans should be 50 - 100 mm, otherwise cracks may appear in the places of their joints;
• from above apply the second layer of the same adhesive composition, covering the grid. As a result, the overall thickness of the reinforcing layer should be no more than 6 mm, while the mesh is located in 1 - 2 mm from the surface.

The wall finish is made 4-7 days after drying the reinforcing layer. Plaster must have high moisture resistance, vapor permeability, resistance to climatic influences and mechanical loads.

It is advisable to perform work at a temperature of +5 to + 300 ° C in the absence of wind and precipitation under conditions of natural or artificially created shadow.

Wet facade materials

Especially carefully needed to take the selection of insulation.
If the polystyrene is chosen, then it must be facade with a density of 15 - 18 kg / m3. Considering that these stainching plates are needed to be treated with antipirens.

It is possible to reduce the fire hazard of the whole structure by placing between the plates of the polystyrene fire prevention inserts of their mineral wool slabs (they are made at the joints of the floors, under window and door openings).

The mineral wool insulation has excellent and does not burn. The density of the insulation should be at least 135 kg / m3. The use of too soft insulation can lead to the bundle of the finish layers. The best quality is basalt insulation.

Advantages and disadvantages of the technology "Wet facade"

The advantages include the following:
• The thermal insulation properties of the building rises to 30%.
• Saves space inside the building.
• The price of these systems is relatively low.
• Using this method increases.
• The small weight of the insulation does not require the strengthening of the supporting structures of the building and the foundation.

• The service life of the wet facade is 25 to 30 years.
• This method allows to significantly improve the appearance of any building, regardless of its age. Reference and repair of the facade during operation are carried out at the level of the finish layer.

The disadvantages of this method are mainly in fairly stringent working conditions:
• It is forbidden to finish the building during precipitation and at high humidity, as this leads to an uneven decay of the solution.
• At temperatures below +50, it is necessary to use forests tightly tightened with film and thermal guns.
• During the production of work to avoid hitting the facade of dirt and dust, surfaces should be protected from wind.

• It is necessary to protect the walls from the sun rays, as they can lead to the drying of the solution and lower its quality.

During the installation of the wet facade, it is necessary to strictly observe and acceptance of the work recommended by the manufacturer of the acquired system. This guarantees the quality of insulation and preserving the attractive appearance of the building throughout the entire service life of the facade.

High-quality insulation and finishing of the facade part of the house guarantee a significant saving of thermal energy, which is particularly relevant in the conditions of a constant rise in price of energy resources. In addition, the complex work makes the house more attractive from aesthetic point of view. There are different methods of insulation and decorating buildings, but the most modern is considered a wet facade: the technology of this method of finishing is described in detail in this article.

Facade insulation with wet methodoutside or inside: Features of choice

Traditional building materials used to build walls, such as brick, wall and concrete blocks, are distinguished by increased strength and rather long service life. At the same time, they do not have a high level of thermal insulation, in connection with which a significant part of thermal energy simply disappears through the walls. In order to prevent this unwanted process, the walls are insulated.

Warming can be both internal and outdoor. In this case, the amount of material, the scope of work and the organization itself, the process within the house are more profitable and cost cheaper. At the same time, there are a number of serious arguments in favor of insulation of the house outside.

The external methods to which the insulation of the wet facade refers to the presence of a so-called dew point - this is a zone where condensate is highlighted in the conditions of temperature differences in the middle of the room and outside. In the case of fastening the insulation on the inside of the carrier wall, there is a high probability of separation of condensate, which leads to high humidity in the room. Therefore, this method of thermal insulation is less functional and even dangerous to health, as against the background of dampness, fungi and mold arise on the walls.

In case of external thermal insulation, the level of heat resistance or thermal inertia of walls increases significantly. In other words, the construction, insulated outside, retains warmly with a significant decrease in the temperature on the street and slowly heats up in the summer heat.

With the outer insulation of the house, the wet facade eliminates all sorts of cold bridges, through which in most cases the main heat loss occurs in the case of the arrangement of internal thermal insulation.

What is a wet facade:features of technology

The external method of insulation of facades has its own classification. Different dry and wet technology. The first option, in turn, includes prefabricated or hinged facades. The main material used in this technology is siding from vinyl or metal. A more practical, highly efficient, economical and attractive externally is considered the wet facade system.

Important!A distinctive feature of a wet facade is a multi-layered, where each individual layer plays its important role in the process of insulation and decorating. To fully implement functions, preference must be given only to high-quality materials.

The use of wet technique allows you to get not only good quality insulation, but also a beautiful decor of the house. An important condition is the use of quality special specialists. The final stage is the process of applying plaster and painting - these are key components of a beautiful appearance of the building.

The technology of the wet facade involves creating a multilayer pie outside. The mounting of the layers to the wall occurs due to the application of special adhesive solutions, mastic and plaster, which is dissolved in ordinary water. Hence the name is the wet facade. The work implies observance of a clear order of sieutenness in the application of the layers: primer, adhesive mixture, heat-insulating plates, additional sizing, grid reinforcement, plastering and painting.

Each phase, involving the use of a wet method, whether it is a sizing, plaster or painting, should be performed at temperatures above +5 ° C. Not only the quality of the work and the degree of thermal insulation, but also the life of the decorative insulation, depend on the sequence of work, materials and compliance with conditions. Otherwise, the facade will soon begin lightering and collapse.

Wet facade: pros and consoutdoor insulation technology

Technology of insulation wet method has a number of indisputable advantages and a certain amount of flaws. Benefits should include:

• high degree of decorativeness and attractiveness of the facade;
• the ease of the heat insulating layer, which allows the use of technology on buildings with a weak foundation;
• reliable thermal insulation that maintains heat in the house for a long time on the principle of the thermos and excluding the appearance of "wool bridges";
• additional protection of the house from destructive atmospheric influences (moisture, freezing, wind);
• reliable sound and vibration insulation;
• durability (the facade, made by wet technology, can serve up to 40 years);

• eliminates the appearance of condensate and, as a result, damp in the house, which is due to the "breathable" outdoor plaster;
• the cost of the wet facade is acceptable, especially in comparison with other methods of insulation;
• the technology does not "steal" the useful space indoors.

Speaking about the pros, the disadvantages of this methodology should be mentioned:

• works should be performed under optimal temperature conditions on the street (if the temperature is below +5 ° C, then it is almost impossible to achieve the desired result);
• each layer requires a certain time to dry, so unforeseen precipitates can negatively affect the quality of insulation as a result;
• dust and dirt getting into operation also adversely affect the result, so the surface should be protected from wind.

Helpful advice! Works on the insulation of the building with a wet facade cannot be carried out during rains. Therefore, planning the installation is better for spring or summer, when precipitation falls much less.

Wet Technology Facade: Step-by-step instructions

Based on the above advantages and disadvantages, it suggests that this technology allows you to create high-quality thermal insulation under the condition of minimal financial investments. The main principle is a clear poetting in applying all the layers. Technology performing work includes three or four stages of the formation of a wet facade. Photo clearly demonstrate it. Each of the layers performs its functional destination.

All stages perform a number of important functions that provide overall reliability, strength and durability of the design, so each of them requires a responsible approach and a detailed study.

Wet facade: Mounting technologypreparatory stage

Before the start of work on insulation should take care of the preparation of the base basis. To this end, the walls are carefully cleaned and eliminate all defects. It is necessary to shine cracks with a solution and align the surface. If strong contaminants are present on the surface, it is recommended to use detergents.

Next, the surface is tested for strength. For this, small pieces of insulation glue the wall. If they hold securely and do not break into pieces, then you can start mounting. If it is easy to cut down with the top layer of the wall, then it is necessary to spend the stripper.

After complete preparation of the wall, a primer is applied to it. And after drying - a layer of glue. If the surface of the house consists of a material with increased absorption, then the ground layer should be more solid. It is better to apply it twice. Old plaster with window and door slopes is recommended to remove in advance.

At the preparatory stage should take care of the installation of the profile plank. The base profile will contribute to the uniform distribution of the load from the plates of thermal insulation and protect the lower row of the insulation from humidity.

Helpful advice! The smooth course of the process can provide a special set for the insulation of the facade sold in construction stores. Well proven itself adhesive mixture for wet facade cerepes.

The profile is mounted at a level of approximately 35-40 cm from the ground with a three-millionx gap between the planks placed horizontally, in case there is an extension under the action of temperatures. The profile is attached directly to the dowel or self-tapping screw. Their amount depends on the density and weight of the selected material for thermal insulation. Most often, they are placed at a distance of 15-20 cm from each other.

Stage of thermal insulation for wet facade: sequence of work

Installation of the thermal insulation layer is one of the main steps, as it is a mounting of the insulation slabs. The process itself requires a clear sequence and execution of a number of rules.

Application of glue to the surface of the plate. The adhesive solution is distributed around the perimeter of the material with a wide strip, retreating from the edge of approximately 3 cm. In the middle of the glue distribute point. The main thing is that more than 40% of the plates area be covered in the adhesive mixture. If thermal mats serve as thermal insulation layer, the adhesive solution should be applied over the entire surface.

Plate laying. The insulation technology wet facade implies the installation of the insulation "in the divorce" by analogy of brickwork. In this case, the tiles should be tightly pressed to each other and to the wall. The glue that has sharpened outwards must be immediately removed. The laying process takes up from the bottom up, ranging from the base profile. It will be necessary to wait 3-4 days so that the glue is completely dry.

Fastening plate dowels. At the next stage, the heat insulating layer should additionally fix the dowels. Their length should be sealed at the calculation of the thickness of the layer of the insulation, the adhesive solution and the reserve for the recess in the wall. If the degree of density of the insulation for the wet facade is high, then for the recess in the recess is sufficiently 5 cm, for porous materials, this indicator should reach 8-9 cm. On 1 m² of the surface will be needed from 7 to 15 dowels. Their amount depends on the density of thermal insulation plates, the diameter of the fastenings and the height of the insulation.

Even before installing a dowel, a nest is prepared under it. Subject to the correct attachment, the clamping sleeves will be lowered close to the insulation.

Wet facade: technologystyling the reinforcing layer

The reinforced base is necessary to ensure a reliable level of adhesion of decorative plaster over the insulation. To this end, a special mesh is attached to the adhesive base, having to sleep in the middle. Installation of the reinforcing layer starts at least two days after applying the heat insulating layer.

Helpful advice! To strengthen it is recommended to use an alkaline-resistant mesh made on the basis of fiberglass having a reliable coating. Otherwise, after a year, the reinforcing layer will begin to collapse, and the plaster simply causals.

First, the grid is fixed on the angular slopes in the openings of windows and doors, as well as in the places of docking vertical slopes and jumpers. Next, go to the corners of the building outside, and at the end - to the rest of the plots.

Select the type of insulation. Features of materials, their advantages and disadvantages. The main stages of the insulation mounting.

The process itself is the application of a layer of special glue. Then the special reinforcing mesh of fiberglass gradually blends into it. It is laid by the mustache, which ensures the formation of a reliable reinforced base. Excessive material is cut. The total thickness of the strengthening layer should be a maximum of 6 mm, while the grid itself is located two millimeters from the surface of the insulation.

When creating a wet facade on buildings with an increased load or on the ground floors, an up-to-rate grid must be used, which is able to withstand higher loads. It is the reinforcing layer that plays a major role in the strength of the whole structure. It ensures the stability of the wall to atmospheric and mechanical influences. It is equally important that the mesh is constrained by alkaline effects of aggressive components contained in the stucco solution.

Plaster wet facade: Decorative Layer Application Technology

The finishing layer plays a double role, as it is responsible for the external attractiveness of the walls and at the same time serves as protection of the heat-insulating layer from external negative impacts. At the same time, the plaster must have a certain porosity to skip excess condensate, providing "breathing" wall.

Decorative finish is the final phase in the process of installation made using a wet facade technology. The plaster is started to apply only after complete drying of the reinforcing layer. For this you have to wait about a week. At the same time, besides high decorative qualities, the plastered surface must correspond to a number of requirements:

• have a high degree of vapor permeability;
• to be resistant to weathering in the form of rain, snow, fog and other precipitation, as well as to the effect of direct sunlight;
• have high strength to mechanical damage.

To make the plaster easily lay on the insulation, the plates should fit tightly to each other. Permissible error - a maximum of 3 mm. Otherwise, the two subsequent layers will not be able to disguise flaws, which will affect the appearance of the entire structure. You will have to either apply a very thick layer of plaster, or come true with irregularities. This fact indicates that it is necessary to select high-quality materials, as well as use a special plastering mixture - for external work.

Helpful advice! The qualitative performance of the work and durability of the service of the plaster affects compliance with the temperature regime. As in the case of fastening the plates, the resulting mixture should be applied at a temperature of at least +5 ° C. The maximum indicator is +30 ° C, since the excessive exposure to sunlight can adversely affect the quality of plaster.

Species diversity of plastering wet facade

The finish stage in the complex of work on the creation of the facade was a wet method is to apply the plastering layer. For the organization of the heat insulating layer, various methods of decorative decoration are used, the main of them will be considered below.

Mineral plaster. The material is a binding mixture, the basis of which is portland cement. The main advantage of this type of coating is to high levels of strength and vapor permeability. The finishing of this type is resistant to the effects of moisture, will not raw and not destroy. The following advantage is at an affordable price. By minuses should include a narrow selection of colors.

Silicate plaster is a variety of mineral, as it contains. Well suited for decorating aerated concrete and foam block walls, as well as for use in the composition of the technology of wet facade, since it has a high level of vapor permeability. However, it should be noted that before it is applied, it will be necessary to cover the surface with a layer of special primer.

Acrylic plaster basically contains a resin in the form of water dispersion. The positive qualities of the material are elasticity and a high degree of adhesion against different surfaces. In order to avoid cracking, the acrylic is applied by a thin layer on a reinforced grid of fiberglass treated with a sealant.

Silicone plaster has a number of unique properties, it is very flexible and driving. Even in the case of a seating of a wall building, covered with a silicone layer is not cracking. This finish is presented in a wide range of colors and has the property of self-cleaning. Thus, the wall itself under the action of precipitation will be cleaned of dust and dirt.

The base of the wet facade: materials for work

Having considered in detail all stages of work, a novice master will be able to assess its strength in terms of self-contained wet facade with insulation. If a positive solution is made, then you should take care of the presence of a complete arsenal of materials and tools. The list below will allow you to take into account all the details. So, this technology assumes the presence of basic materials:

1. Thermal insulation plates as a base material require a special approach in the selection. It is necessary to calculate the thickness of the plates in advance, from which the degree of thermal insulation depends, and to explore the characteristics of different insulation.
2. The base profile is selected taking into account the width and thickness of the selected heat insulating plates. The number is calculated based on the size of the building.
3. A grid for a wet facade, which serves as the strengthening of the entire structure, most often is a rolled material from fiberglass. For buildings with high load use more reliable grids.
4. The glue for the wet facade is used to fix the plates. Pick it in accordance with the selected insulation.
5. Decorative stucco is applied at the final stage. You can use ready-made compositions.

Helpful advice! In the choice of materials for the manufacture of a wet facade primarily guided by the qualities and features of the selected insulation. For example, glue for minvati is not suitable for fixing foam plates and vice versa.

Additional materials for creating a wet facade with their own hands

The above list of materials is considered the main, but far from comprehensive. If you do not take care of the purchase of a full set before making a wet facade, a number of inconveniences and difficulties may occur during the project implementation.

The primer is applied at the preparatory stage in order to ensure better clutch of plates and walls. The type of primer is selected in accordance with the type of decorative plaster.

The composition for plastering the protective and reinforced layers is applied directly to the insulation, although it is often confused with decorative plaster. These are different compositions - and it should be considered. One of the main differences is a higher price of plastering.

Paint is designed to decorate the walls and serves as a certain protection against atmospheric influences. Do not neglect this material and save on it.

The required component of the part of the mushroom shape is the part. It would seem a trifle, but without them there will be no reliable fixation of the plates. Therefore, their acquisition should be taken in advance.

Dowels for fastening the base is a separate element, very important at the preparatory stage. The length of the dowel-nail depends on the material of the wall where the profile is attached. In the installation process, the base should also take care of the presence of special elements for connecting in places of bends and in the corners.

In order to acquire a complete set, manufacturers offer comprehensive systems where all the necessary materials and tools are already included to create a wet facade. At the same time, not every set takes into account the individual needs of the owners, and therefore, when buying such sets, you need to be attentive.

Tools required for insulation of walls wet facade

A list of tools for performing work on the technology of a wet facade should include almost the entire arsenal of an experienced builder and a number of special devices that will greatly make it easier and speed up the process. In particular, you will need:

• the square required for the markup of straight angles and angles at 45 °;
• construction level designed to determine the degree of deviations of parts from surfaces in a horizontal or vertical direction;
• roulette for measuring the length and width of various materials;
• flooring hammer, designed to work with different materials;
• saw with small teeth to cut polyfoam materials;
• construction mixer for kneading dry construction mixes from sand, plaster, glue, putty;
• rollers to perform primer at different stages and for staining the finish layer of decorative plaster;
• swiss ironers used to cover the surface with different mixtures and for their smoothing;
• ironing with teeth, used for amplifying and fixing by the "insertion" by the reinforcing layer;

• simple ironing of plastic for applying plaster and plaster compositions;
• trowel for easy kneading solution;
• spatulas and Kelma of various sizes;
• milling cutter for deepening dowels when attaching plates to the wall;
• pistol for sealant.

Helpful advice! The acquisition of tools should take care at the preparatory stage. This list is maximum and extensive, but it is possible that additional tools may be needed during the work.

Wet facade insulation: variety of materials and selection features

Facade insulation are divided into two large groups - polystyrene and mineral wool products. Foam materials are characterized by ease, fast installation and high levels of heat shields. The main disadvantage of the material is its flammability. Minvata for the wet facade is an order of magnitude more expensive, while being more reliable in its operational qualities. Plates from this material are not burning, have a high level of vapor permeability.

The density of mineral wool for the wet facade should be at least 150 kg / m³, and the strength limit is at least 15 kPa. Preference in the selection is recommended to give plates from basalt fiber. As for the foam, it is necessary to choose a special purpose with weak flammability for insulating work. Specialists do not advise in this field to use extrusion polystyrene foam, which has low vapor-permeable characteristics and having weak adhesion with adhesive solution.

In different conditions, various types of insulating plates are used. The choice is guided by the physical and chemical characteristics of the insulation, based on its specific destination. At the same time, each group of insulation has its own classification.

Minvat under the wet facade: Materials for the manufacture and their advantages

So, the plates from mineral wool are not suitable for finishing facades. This advantage is due to a number of specific positive characteristics:

• durability;

• fire resistance;
• excellent vapor permeability;
• high level of heat and sound insulation;
• resistance to the effects of chemical and biological substances;
• ecology;
• easy installation.

In addition, individual types of wool, in particular products on phenolic binders, are distinguished by a high level of moisture resistance. Most preferred are plates from diabase or basalt wool for wet facade. The price of such a insulation is significantly higher than other analogues, but this is the case when paying precisely for quality.

Since the strength of Minva you must start from 15 kPa, and the material itself should not enter into a reaction with plaster, the use of fiberglass plates in this area is impractical. This is due to the fact that such minvat is easily destroyed in an alkaline medium and does not have sufficient breaking strength.

Fiberglass slabs will begin to crumble under the influence of alkalis, which are contained in the base reinforced layer and adhesive solution. The pH level of these materials on average is 12.5. The corresponding reaction begins not immediately, but after a couple of years. Destruction occurs especially intensively under the influence of strong winds. Thus, a very fast wet facade of fiberglass plates will be unusable.

Additional qualities as the criteria for choosing a mineral insulation under the wet facade

An important indicator in the choice of heat-insulating plates is the coefficient of moisture absorption. It is desirable that its level is at a rate of 15%, since the moisture that has absorbed into the material will lead to its inevitable deformation and will negatively affect the thermal conductivity. Plates with a high degree of moisture absorption do not provide the required level of monolithic facade. As a result, this design will not serve for more than two years.

Helpful advice! The density density of the wet facade must vary from 150 to 180 kg / m³. Otherwise, the process of applying the finishing layer is complicated and the risk of separating the entire thermal insulation coating of the facade appears.

The technology of the wet facade on the Minvat involves the selection of the plates in such a way that the degree of vapor permeability from the first (preparatory) to the last (decorative) layer gradually increased. Compliance with this requirement will provide favorable prerequisites and prevent condensate falling in the middle of the structure. In the climatic conditions of Russia, most of the time, the temperature indicators inside the houses are significantly higher than outside. Such conditions significantly increase the likelihood of condensation.

Wet facade of foam: features of the material and requirements for its choice

Another group of insulation, the main raw material in the production of which is served by polystyrene foaming, has a certain list of positive qualities. It should be noted here:

• low cost;
• ease of material;
• high thermo- and sound insulation;
• vapor permeability;
• environmental friendliness;
• ease of installation.

The list of disadvantages of foam plates significantly exceeds similar characteristics of minvati. The most important minus is a flammability of the material. In order to exclude this shortcoming manufacturers handle insulation with special chemicals - antipyrenes. Thus, even in the case of ignition, the spread of the fire will be suspended, that is, the flame can sink itself.

Fireproofing also provide special inserts from non-combustible materials, in particular from mineral wool. The use of such a method led to the appearance of a separate combined material.

Among other minuses of material is a low degree of biosis. In the foam can live insects and even rodents. Also, polystyrene plates are more fragile, which creates certain problems in the installation process, and less wear-resistant in operation.

Requirements for polystyrene foam plates for wet facade: price and quality

Before you buy a material for a wet facade of expanded polystyrene, it is necessary to study its characteristics and compliance with all requirements. It must have a strength to break the minimum of 100 kPa and have a density of 15 to 25 kg / m³.

Helpful advice! The choice of material in accordance with all the requirements for it and its correct installation, with accurate observance of the technology of the wet facade device, the insulation guarantees its service life for 20-30 years. Repair of the decorative layer will have to produce a little more often, but the costs will be significantly less.

Qualitative material can be defined even by external data. The insulation granules should most closely lie down to each other and have approximately the same size. Otherwise, such a foam will bring maximum problems starting from the installation process and ending with direct operation. Low-quality coarse-grained material absorbs an increased amount of moisture, which, in turn, entails its deformation and leads to the loss of thermal insulation qualities and early destruction of the facade

The form of thermal insulation plates from polystyrene foam should be the same as the right rectangle. The error is allowed not more than 2 mm per 1 m. The drops in the thickness of the insulation can be a maximum of 1 mm, and the deviation on the surface of the faceplane should not exceed 0.5%. Otherwise, it is impossible to produce without defects the insulation of the facade of the house. Wet facade outside will have low aesthetic characteristics, and its service life will be reduced several times.

Material consumption for wet facade arrangement: photo of private houses

As with other types of construction work, the consumption of materials is carried out approximately, based on the required amount of 1 m² of the finished wet facade. Warming at home outside suggests the following costs:

• primers will need approximately 250 milliliters per 1 m²;
• the adhesive solution for fixing the heat insulating plates is spent at the rate of 10 kg per 1 m²;
• the consumption of the insulation itself with a thickness of the plate at least 5 cm corresponds to the insulated area;
• dowels for fastening the plates will need about 5 pieces per 1 m²;
• the mesh for the wet facade is consumed at the rate of 1.3 m² per 1 m²;
• plasters for the leveling layer should be purchased based on the needs of 0.3 kg per 1 m²;

• the separation consumption for the finishing layer is approximately 0.3 kg per 1m²;
• a finished decorative plaster will need about 3 kg per 1 m².

In order to correctly calculate the required amount of materials, you need to be guided by the instructions on the packages of the material, and it is better to purchase ready-made sets. In this market segment, the wet facade of Cerezite has proven itself well. The technology of facade insulation using mineral wool plates involves the use of the Ceresit WM brand.

For insulation with the use of foam on technology, the wet facade Creste is marked with VWS. Plates for thermal insulation are treated with adhesive composition and fasten on the wall, a special protective layer with reinforced glass is applied on top. The system of the corresponding brand contains all the necessary materials.

The components of the price of a wet facade for m 2

The price of the finished wet facade includes the total cost of preparatory, assembly and decorative work. Main costs fall on materials based on the cost of 1 m² for a deaf wall.

Important! The main component of the total value of the wet facade is the price of the insulation, which depends on its type, density and mineral additives.

The total cost of the finished system is the total price of components components:

• adhesive mixture for fastening the insulation;
• plaster mortar for the base;
• mixtures for decorative plaster;
• fiberglass grids for the reinforced layer;
• dowels and other fasteners;
• two types of primer;
• heat insulating plates.

Finished systems usually do not take into account the cost of additional and optional parts, various profiles and auxiliary fasteners. Also, not all manufacturers offer insulating materials in the complex. In this case, it should be borne in mind the average cost of the insulation. For example, the average price of minvati for a wet facade with a thickness of 10 cm is about 650 rubles. For 1 m². The cost of polystyrene foam in the same indicators – about 250 rubles.

Thus, the price of a wet facade per m² with plates from Minvati will be about 1,200 rubles. The thermal insulation system from polystyrene foam will cost much cheaper - about 750 rubles. For 1 m².

Arrangement of the wet facade: the cost of work form² to order

The total cost of installation of the insulation and its decoration includes payment of services of masters or contractors. This is if the work is not made independently. The total price ranges from 1000 to 2500 rubles per square meter. It all depends on the total work, the type of materials and the method of decorative design of the finished wall. The main components and the average price of mounting the wet facade are shown in the table below:

Type of work performed	Cost, rub. / M²
Installation and disassembly of forests for construction	130 – 150
Surface primer taking into account deep penetration	60 – 90
Fastening insulation with adhesive makeup and wall leveling	370 – 450
Installation of the reinforcing reservoir with a base plastering layer and sealing flush	330 – 370
Grinding walls using quartz sand	65 – 75
Decorative shuttering of various types	240 – 350
Decoration of stone on the facade basement	870 – 920

A wide range of prices for wet plaster facade is justified by varying degrees of complexity of the decoration process. The list may also include additional work, for example, the installation of decorative elements. Their cost is calculated separately and depends on complexity.

Additional factors affecting the cost of wet facade

The above services and their cost are not constant. The list can be much more, and the price increases due to the advent of additional costs. The final price for m² of wet facade turnkey depends on a number of additional factors. In particular, it should be considered:

• the initial appearance and structure of the facade;

• the presence of flaws and damage;
• the level of complexity of the work performed;
• the total number of openings for doors and windows, as well as their location;
• qualitative characteristics of materials and their number;
• total work.

Helpful advice! Calculation calculation is made individually for each specific case. Sometimes, even with the identical list of works and the same area of \u200b\u200bprocessing, the price may differ significantly.

Thus, the final cost includes additional costs. For example, labor-intensive work at high altitude will require the installation of auxiliary mounting forests. The cost of their lease depends on the height and time limit. It should also be noted that high-altitude work is much more expensive, as they suggest the availability of special skills and organization of insurance. The formation of the price is influenced by the costs associated with the delivery and characteristics of individual facades.

Installation of wet system will cost an order of magnitude cheaper than the arrangement, but its further operation will cost more. The wet facade technology is usually used for insulation of private houses, and ventilated - for finishing larger buildings. What it is connected, Consider below.

Ventilated facades: Pricedictated by quality

Speaking about the scope of application of the Wet Facade method, it is worth mentioning such a feature as limited resistance to the effects of temperature differences. Based on perennial studies, the European Association of Plaster-type thermal insulation systems came to the conclusion that the technology of the wet facade is appropriate not in all climatic conditions.

Even the most reliable and expensive materials, installation in compliance with all requirements do not give a long-term guarantee of service in the conditions of an intra-engineering climate of moderate latitudes, which prevails on a significant part of Russia. For the starting permissible point of application of the system, the wet facade, the academic associations took grapes, or rather the plant itself, and the cycle of its ripening. That is, in the zone where climatic conditions allow ripening at least one of its varieties, the use of technology is appropriate.

In conditions of constant rains and high humidity, for example, in close proximity to the sea, the use of this technology is undesirable. This is due to the weak moisture resistance of this type of facade. If the wall is subject to frequent mechanical effects, the installation of the wet facade is also not recommended.

Based on the listed contraindications, the alternative technology of the facade of the plastering type in the form of a mounted thermal insulation system with an air gap was invented. Simply put - ventilated facade. What are similarities, differences and advantages of this type of buildings insulation - will figure it out further.

Helpful advice! Check the quality of thermal insulation under the ventilated and wet facade can be used using thermal imager. Warm tones in the photo show heat losses, and dark - heat resistance of walls.

Comparative characteristics of the ventilated and wet facade: photo of houses and buildings

The mounted system differs from plastering the fact that when installing the wet facade, the plaster is applied directly on the layer of thermal insulation. The ventilated facade involves the installation of the front panel from fibrcement at a certain distance from the insulation, which creates the necessary protection against atmospheric precipitation. In addition, thanks to the protective screen, excessive moisture, which appeared behind the facade panel, can evaporate through the air opening.

Thus, the ventilated facade has an additional, compared with the wet method, the number of functions and provides:

• additional protection against moisture, as well as sound insulation;
• the highest degree of inflammation protection;
• cool in the room in the summer, which allows you to save on air conditioners;
• eliminate flaws on the wall in the form of irregularities and curvatures;
• ease and speed of installation;
• a wide selection of design options;
• additional thermal insulation, which contributes to the presence of an airbag.

In addition, the coating of fibrcement does not require auxiliary maintenance and repair of the decorative layer in several years. Attachment can serve without interventions of several decades.

Solving a dilemma, which facade to choose, can be guided by the following recommendations. The wet facade is appropriate in the case when it is necessary to minimize the cost of finishing the building and minimize the load on the walls. In this way, you can make ideally smooth walls, without complying with special requirements for the strength and wear resistance of the facade.

Attachment, in turn, compensates for the irregularities of the wall and helps hide any defects. The installation of the ventilating facade can be carried out at any time of the year, even at a negative temperature.

Scope of the wet facade and ventilated facade

The scope of applying ventilated facades is much wider. They are used to insulate private houses, finishing multi-storey new buildings and public buildings. The most widely used to decorate shops, cafes, shopping and entertainment centers and other socio-commercial institutions.

Important! Wet facades are used for thermal insulation of buildings with low storeys and utility rooms, as well as if necessary, saving on the insulation. As a budget version, this method is also applicable in the energy saving system of government agencies and public buildings.

In the facing of ventilated facades, various materials are used, in particular:

• porcelain plate;
• aluminum and composite panels;
• fibrocement;
• plates of laminate produced under high pressure.

The main advantages of the porcelain facade are in its strength, a variety of coloring and high aesthetic characteristics. But there is such a material quite expensive. The price of aluminum composite panels is more democratic. The material itself is universal, and thanks to a wide range of colors and structures allows you to realize the most bold fantasies of the architect.

Fibrocement - material imitating stone, resistant to moisture and sun. It has simplicity of installation and an open type of fastening. Its more often used for lining of residential buildings. Laminate panels are a new material having different colors, texture, resistant to weathering and fire, it is lightweight, durable and environmentally friend. In addition, it is cheaper than porcelain stoneware.

Wet Facade Technology on Minvat: Instructions, useful tips and secrets of masters

If, after considering all sorts of insulation options, the choice was made in favor of the wet facade with the use of mineral wool slabs, and it was decided to make work independently, then a number of secrets of masters should be taken into account.

Start standing from the selection of the material. So, on the Internet and special pattern, you can meet a recommendation for the replacement of minvati on fiberglass. This is a misconception, since over time, fiberglass plates begin to see the vibrational effects, and the so-called cold paths are formed in the insulating layer.

To achieve the maximum heat-insulating effect, it is worth taking care of insulation not only the facade, but also gender, as well as the ceiling. In particular, it concerns apartments over unheated premises or on the upper floors.

Subject to the correct choice of material and strict compliance with the instructions, the warranty period of the facade can reach the half-century mark. Additional protection of the finishing layer of plaster will provide a special paint coating, which also will prolong its service life. For this purpose, it is worth using water dispersive paint with acrylic, silicone or silicate impurities. Its color variety includes more than a thousand shades.

Helpful advice! During painting, look at the design and estimate documentation, where the original color of the construction is indicated, the new shade must match it.

Conditions for successful insulation using a wet facade installation technology: video recommendations

Wetting insulation should occur in full protection from frost and atmospheric precipitation. If the work does not require deposit and its completion occurs in adverse conditions, then take care of the construction of special forests and cover them with a dense film, which will ensure temporary protection against wind and moisture and create a small heat outline.

Before starting work on the installation of a wet facade, it is necessary to close all access to the inside of the room from the windows and doors. All internal draft work in the house is better completed before the start of insulation. On the wall outside, it is necessary to place a row of fasteners and brackets in advance that will hold air conditioners, cameras, fits or drain pipes.

With adhesive solutions, it is necessary to work in the shade or at elevated clouds, the maximum excluding the ingress of the sun's rays to the mixture. The distance between the heat-insulation plates and the reinforcing grid should be at least 2 mm, which ensures the fill of the adhesive.

For the overall strength of the multilayer design to dry out each layer, it is required to give a few days. Hurry in this case is unacceptable. The operational characteristics of decorative plaster depend on the conditions of work. Optimal prerequisites are temperatures over 5 ° C, elevated cloudiness, dry windless weather.

For plaster, it is necessary to select exclusively materials for external work, which will be able to fully resist negative impacts. The upper plaster layer should have a high level of thermal conductivity and moisture resistance, to be durable and resistant to mechanical, chemical and atmospheric influences.

House insulation wet facade: summarizing

The technology is wet facade, although inferior in a number of operational characteristics to the ventilated facade, is the leader among existing methods of insulation. Its advantages are to apply modern high-quality thermal insulation materials, some of them can reach half a century. Special exterior decoration with high aesthetic characteristics not only guarantees the external beauty of modern residential buildings, but also makes this technology admissible in the restoration of architectural attractions.

To achieve the highest result, you need to trust the work of certified firms, as well as to use high-quality materials manufacturers who have proven themselves in the construction market. To prevent the occurrence of chemical reactions, it should be noted that individual components must be compatible with each other. Each subsequent layer should have an increased level of vapor permeability in relation to the previous one. Do not forget about the strength and density of materials and their compliance with fire and environmental requirements.

The design is designed to ensure a high degree of sound protection in two directions (both from the inside and outside the house). The quality of the materials affects a longer life of not only the insulation layer, but also at home, protecting the walls from precipitation and mechanical damage. The facade closes the main construction from the effects of wind, frost, pollution, ultraviolet and humidity.

Finally, it should be noted that the use of a variety of decorative plaster options in the wet facade system, finishing elements and color design allows you to implement various style ideas on the outside of the building, which cannot be done using other methods of insulation, for example, the technology of the ventilated facade.

Creating a wet facade is one of the easiest ways to facing the front of the building. This option is used quite often, because the work can be performed without the use of complex equipment and availability of professional skills. But the process has certain rules and nuances, which allows you to get reliable and durable coating.

It is clear from the name that this method implies the use of materials that have a liquid structure. That is, the final cladding is created by applying various types of plaster.

The "wet facade" system includes many layers, so the design resembles a cake. This method is used for quite a long time, which speaks of its effectiveness. Unlike the "dry" option, which is fixed with the finishing materials on the base or frame with the help of special holders or self-sams, wet has a completely different technology.

From simple facade plaster "Wet facade" is distinguished by the presence of powerful thermal insulation

The peculiarity of this method is the possibility of full leveling of the dew point. This is achieved due to the fact that all elements have a common bundle, and the surface is almost completely devoid of joints.

Since the design being created relates to non-ventilated facades, all work is carried out with mandatory thorough preparation of the foundation.

Pros and cons

Advantages of the system:

1. Decorativeness. The texture and the color of the outer layer depends solely from the designer plan. The work is carried out by various types of plaster, which can have a variety of texture and stain in the desired shade. Excellent result can be achieved by using a stencil creating a masonry of a stone or brick.
2. Availability. All materials used in work have a democratic cost. Naturally, costs depend on the type of plaster and putty.
3. Small weight. The total mass does not have a serious load.
4. Additional heat and sound insulation. The multi-level structure reliably protects against noise pollution, and also contributes to the preservation of heat and creating a comfortable microclimate.
5. Lack of condensate. It arises due to the fact that the dew point appears in the inner parts of the walls. In this case, it moves to the insulating layer and the excess moisture evaporates without any problems.

With outer insulation, the dew point moves in a layer of heat insulation, respectively, the condensate is completely absent

It is impossible to exclude substantial disadvantages:

• Installation of the wet facade is carried out exclusively under favorable weather conditions. Temperature and humidity indicators are largely dependent on specific products.
• If atmospheric precipitation falls out during work, the process stops until the surface has complete.
• Hot sunny days after the end of all procedures are also negatively reflected on quality: numerous cracks appear on the upper layer with rapid drying. This reduces the level of security of the object and reduces the service life of the coating.

The correctness of the work is important and the correctness of the work, any violations can threaten serious problems in the future.

For urban residents "Wet facade", in fact, the only way is good and for a long time to insulate housing without loss of square meters

System device

The wet facade device does not include complex schemes of layout and location of materials. It is important to accurately and consistently carry out technological stages.

System structure:

1. The insulation is attached to the base with the help of adhesive composition. The fixing solution should have good adhesion and not affect the material. The thermal insulation products are chosen by such a thickness that is necessary for a particular case, taking into account the nature of the terrain. Modern species are the best: foam and penplex. Special dowels with a big hat are used as the main fastener.
2. Top thermal insulation is stacked with a layer of solution. The reinforcing mesh is fixed on it and is completely covered with the composition.
3. As a cladding, there is a plaster, which is applied with a layer-required layer depending on the selected products.

On a note! The last coating may be paint that protects the surface from premature destruction and give an attractive appearance.

The popularity of the outer insulation system "Wet facade" is largely due to the available value of the main materials and simplicity of installation.

Montage with your own hands

The technology of mounting the wet facade assumes that the laying of the insulation and all subsequent layers are proceeded after other events are completed. This list includes flooring or partial replacement of the roof and overlaps; Protection of the foundation and preparation of the base for further actions; Installing all external and going inside communications. Works are recommended to start after the building shrinkage. The object, including inner premises, should be well succeeded.

There is an opinion that under the "wet facade" the walls need to be thoroughly aligned, in reality the differences up to 20-30 mm can be levelified by mounting glue

To achieve a better result, the process is divided into several stages:

1. Preparation.
2. Laying insulation.
3. Creating a reinforcing layer.
4. Finish events.

It is necessary to clearly observe the sequence of all stages.

Preparation of material and base

Works begin with the preparation and acquisition of the necessary materials and tools:

1. The surface is cleared of dirt and dust. If there is an old layer, then it is completely removed.
2. Much attention is paid to checking the coating on the traces of fungus and mold. If there are damaged areas, then the problem is eliminated.
3. Cracks and cracks are expanded and put off with putty.
4. If there is a strong base of base, then alignment is performed.
5. The surface is ground.

The initial processing of the walls of the primer is mandatory, the composition is chosen depending on the form of the base (wood, brick, concrete, cellular concrete), if the specialized soil found failed, then you can take a universal

Further work is embarked after complete burials.

Laying insulation

The insulation is purchased with a slight margin. Fixation occurs as follows:

1. At the selected distance from the Earth (this parameter is due to further operations with the basement) the starting profile is installed. It is fixed through special gaskets to ensure the mobility of the structure at a temperature expansion. As an alternative, a suitable metal profile is used.
2. The plates of thermal insulation are stacked on the prepared glue. Fixation begins with the first row. The upper parts are located with a displacement to avoid matching vertical joints, for this one element is cut in half.
3. After grapping the adhesive, holes are drilled and the dowels are installed, which fix the insulation.
4. If required, the joints are slightly rolled. Surplus foam are cut off.

If the facade is smooth, then the glue on the insulation is better to apply an octoral toothed spatula, with the lining of the curves of the walls, the composition is applied with a thick layer of fragmentary, as in the photo number 1

The next stage is embarked after 2-3 days, depending on the type of adhesive composition.

Creating a reinforcing layer

The reinforcing layer is created in the following order:

1. A basic plaster mixture or adhesive composition is prepared.
2. Application is carried out using a spatula. First, the thin layer is stacked equal to the size of the first fiberglass tape.
3. The reinforcing canvas is pressed into the solution and is covered with the composition. Mesh docking places are made.

Mounting glue under the fiberglass mesh can be applied to the "naked" insulation, if it is decided to use the starting plaster, then the insulation is desirable to predict

The total thickness of this layer should not exceed 5-6 mm. It is necessary to wait for the drying of the surface, after which it is coated with the primer and leave until the final misfortune.

Finish work

For this stage, facade plaster is selected. It includes many species, various properties. The main requirement is vapor permeability.

After the starting of the starting reinforced layer, it is embarked in the finish line, which can use any decorative plaster for facades.

The selected finish mix is \u200b\u200bprepared and stacked with a small layer using a spatula. The solution is applied consistently and thoroughly resurrected by the rule. When working with decorative plasters, the mixture is used according to the recommendations that are indicated by the manufacturer. The final stage may be priming and staining. To achieve a better decorative effect, combine shades.

Installation of the "wet facade" system is not of great difficulty, but requires time and strength.
