Wet facade: technology, keeping up with the times

High-quality insulation and finish front of the house provide a significant saving of thermal energy, which is particularly important in conditions of constant rise in price of energy. In addition, a comprehensive execution of works makes the house more attractive from an aesthetic point of view. There are different methods of insulation and decoration of buildings, but is considered the most advanced wet facade: The technology of this method of finishing described in detail in this article.

Thermal insulation of facades wet outside or inside: particularly select

Traditional building materials used for the construction of walls, such as brick, angina and Betonobloki, characterized by high strength and sufficient durability. At the same time they do not have a high level of thermal insulation, due to which a large part of the thermal energy just disappears through the wall. In order to prevent this undesirable process insulated walls.

Thermal insulation may be both internal and external. At the same amount of material, amount of work and organization of the process itself is more profitable and less expensive inside the house. At the same time, there are a number of serious arguments in favor of the insulation of the house outside.

External methods which include wet insulation façade, suggest the presence of the so-called dew point - it is an area where condensate is released under the conditions of temperature changes in the middle of the room and outside. In the case of fixing insulation on the inside of the bearing wall there is a high probability of condensate separation, which leads to increased humidity. Therefore, this method of insulation less functional and even dangerous to health, as in the background of damp on the walls appear fungus and mold.

If external insulation is significantly increased level of thermal inertia or heat-resistance of the walls. In other words, the construction, with insulation on the outside, over long retains heat at a much lower temperature outside and slowly heated in the summer heat.

When the outer home insulation wet facade eliminates all kinds of cold bridges through which most of the heat loss occurs in the case of basic arrangement of the internal insulation.

What is a wet facade: technology features

The outer facade insulation method has its own classification. Distinguish between dry and wet technology. The first option, in turn, involves teams or curtain walls. The basic material used in this technology, - vinyl siding or metal. More practical, high-performance, cost-effective and attractive appearance is considered to be wet facade system.

Important! A distinctive feature of the wet facade - layering, where each individual layer plays an important role in the process of insulation and decoration. To fully implement the functions of the preference should be given to only the highest quality materials.

Use of wet method provides not only good quality insulation, but also a beautiful home decor. An important condition - the use of high-quality spetsrastvorov. The final stage is the process of plastering and painting - are key components of the beautiful appearance of the building.

wet facade technology involves the creation of a multi-layer cake outside. Fixing to wall layers occurs due to the application of special adhesive mortars, cements and plaster, which is dissolved in ordinary water. Hence the name - Wet facade. Job requires compliance with a clear prioritization in the application layers: primer, adhesive mixture, insulating boards, more sizing, net reinforcement, plastering and painting.

Each phase involving the use of a wet method, whether the sizing, plaster or paint, must be performed at a temperature higher than +5 ° C. From the sequence of work, materials and compliance with the conditions depend not only on the quality of work and the degree of thermal insulation, but also the life of decorative insulation. Otherwise facade will soon begin to crack and disintegrate.

Wet facade: pros and cons exterior insulation technology

wet insulation technology has a number of advantages and a certain number of drawbacks. The benefits should include:

• high degree of decorativeness and attractiveness of the facade;
• ease of thermal insulation layer, which allows the use of technology on buildings with weak foundations;
• reliable thermal insulation that retains heat in the house for a long time on the principle of the thermos and eliminates "cold bridges";
• extra protection at home from the ravages of weather (moisture, frost, wind);
• robust sound and vibration isolation;
• durability (facade formed by a wet technology, can last up to 40 years);

• eliminates condensate and, as a consequence of dampness in the house, that is due to "breathing" outer plaster;
• cost wet facade acceptable, especially when compared to other ways of warming;
• technology does not "steal" the usable space in the room.

Talking about the advantages, disadvantages and should be mentioned, which is the methodology:

• Work must be carried out under optimum conditions of temperature outside (if the temperature is lower than +5 ° C, to achieve the desired result practically impossible);
• each layer requires a certain time for drying, so unanticipated precipitation could adversely affect the quality of thermal insulation in the end;
• dust and dirt from entering the work process also adversely affects the outcome, so the surface must be protected from the wind.

Useful advice!Insulation works building wet facade can not be carried out during the rainy season. Therefore, the installation of better planning in the spring or summer, when rainfall is much less.

Technology Wet facade: step by step guide

Based on the above advantages and disadvantages, the conclusion is that this technology allows you to create high-quality thermal insulation provided minimal financial investment. The main principle - a clear phasing in applying all the layers. work performance technology includes three or four stages of formation of the wet facade. Photos clearly show this. Each layer performs its functional purpose.

plaster	Major works	function
Adhesive or preparation	Preparation of the base, the installation of fasteners and adhesive primer	Determines the degree of reliability of fastening of future construction
Thermal insulation	Fastening insulation board with an adhesive and anchors	It provides a degree of insulation of building walls
Reinforcements	It includes the installation of reinforcing mesh	It ensures the strength and reliability of the construction and provides a base for the final finishing layer
Decorative	Application of decorative plaster and paint a variety of ways	Protects the insulating panels weatherproof and provides the external beauty of the walls

All steps are performed a number of important functions to ensure the overall reliability, strength and durability, so each of them requires a responsible approach and the detailed study.

Wet facade: mount technology preparatory phase

Before starting work on warming should take care of the preparation of the basic framework. To this end, the walls are thoroughly cleaned and eliminate all defects. It is necessary to cover a solution of cracks and smooth the surface. If the surface of heavy dirt present, it is recommended to use detergents.

Next, the surface is tested for strength. To do this, on the wall glue small pieces of insulation. If they are kept securely and do not break into pieces, then you are ready for installation. If easy to come off together with the upper layer of the wall, it is necessary to carry out the cleaning again.

After full preparation walls painted with a primer. After drying, - a layer of adhesive. If the surface of the house consists of a material with high absorptivity, the ground layer must be more solid. It is better to apply it twice. Old plaster with a door and window slopes is recommended to remove in advance.

In the preparatory phase should take care of installing the profile section. Plinth profile will facilitate uniform distribution of the load on the insulation plates and the lower row of insulation to protect from moisture.

Useful advice! The smooth course of the process can provide a special set for thermal insulation of the facade, sold in DIY stores. Well proven adhesive mixture for wet facade Ceresit.

Profile mounted at about 35-40 cm from the ground with trehmillimetrovym gap between slats, arranged horizontally, in the event that if an extension under the influence of temperature. Profile mounted directly on the dowels or screws. Their number depends on the density and weight of the material chosen for insulation. Most often they are placed at a distance of 15-20 cm from each other.

Phase insulation for wet facade: the sequence of work

Mounting of a thermal insulation layer - one of the main stages, as is a fixing insulation boards. The process itself requires compliance with a clear sequence and perform a set of rules.

The application of glue on the plate surface. The adhesive solution was spread over the perimeter of the broad strip material, departing from the edge of about 3 cm. In the middle of adhesive dispensed dot. The main thing is that the adhesive was covered with a mixture of 40% of the plate area. If the insulating layer are lamella mats, the adhesive solution should be applied over the entire surface.

Laying slabs. Wet insulation technology involves the installation of facade insulation "in the run-up" on the analogy of brickwork. In this case, the tiles should be tightly pressed against each other and against the wall. Glue treads out must be removed immediately. Laying process takes place upwards from the ground profile. We need to wait 3-4 days, so that the glue is completely dry.

Mounting plates with dowels. In the next step the heat insulation layer must be further fixed dowels. Their length is chosen for calculating the thickness of the insulation layer, the adhesive solution and stock in a recess in the wall. If the degree of insulation density for wet facade high, the storage recess is sufficient to 5 cm, for porous materials, this figure should reach 8-9 cm. For 1 m² surface required from 7 to 15 plugs. Their amount depends on the density of the thermal insulation boards, the diameter and height mounts a heater location.

Before installing anchors beneath prepare the nest. With proper mounting clamping sleeve will accommodate close to a heater.

Wet facade: Technology laying a reinforcing layer

Reinforced framework is required to provide a reliable level of adhesion of plaster on top of the insulation. For this purpose, a special mesh is attached to the adhesive base, pushing it into the middle of it. Installation of the reinforcing layer begin after at least two days after the application of the thermal insulation layer.

Useful advice!To strengthen the recommended stable to alkaline resistant mesh made based on glass fibers having a reliable coverage. Otherwise, in a year a reinforcing layer will begin to crumble and plaster simply osypletsya.

First, the grid is attached to the angular slopes in the openings of windows and doors, as well as in places of joining of vertical slopes and bridges. Next, go to the corners of the building from the outside, and in the end - to the other sites.

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

The process itself is the application of special adhesive layer. Then it gradually gently utaplivajut special reinforcing mesh of fiberglass. It overlapped that ensures the formation of a robust reinforced base. Excess material is trimmed. The total thickness of the reinforcing layer should be up to 6 mm, and the grid itself is in two millimeters from the surface of the insulation.

When creating a wet facade on buildings with increased load on ground floors or necessary to apply a hardened armored grid which is able to withstand higher loads. That reinforcing layer plays an important role in the strength of the whole structure. It provides the wall resistance to weather and mechanical influences. It is equally important that the grid opposed to corrosive alkali components contained in the solution plaster.

Wet plaster facade: technology for applying the decorative layer

Finishing layer plays a dual role, as responsible for visual appeal and walls at the same time serves to protect the insulation layer from adverse external influences. In this case, the plaster should have a certain porosity to pass the excess condensate, providing "breathing" of the wall.

Decorative trim - is the final phase in the process of installation, performed by the wet facade technology. Begin plaster applied only after the complete drying of the reinforcing layer. It will have to wait about a week. At the same time, in addition to high decorative qualities, plastered surface should meet certain requirements:

• have a high degree of water vapor permeability;
• be resistant to atmospheric effects such as rain, snow, fog or other precipitation, as well as to the effect of direct sunlight;
• have high strength to mechanical damage.

To plaster is easy to lay on the heater, the plate should fit snugly together. The margin of error - a maximum of 3 mm. Otherwise, the next two layers will not be able to mask the flaws that affect the appearance of the whole structure. Will either apply a very thick layer of plaster, or to reconcile with irregularities. This fact indicates that it is necessary to select high-quality materials, as well as use a special mixture of plaster - for outdoor work.

Useful advice! On the quality of work life and durability of plaster effect observe the temperature. As in the case of fixing plates, a working mixture should be applied at a temperature of at least +5 ° C. The maximum rate of +30 ° C, since excessive exposure to sunlight can adversely affect the quality of the plaster.

Species diversity of wet plaster decoration facade

The final stage in a complex of works on creation of the facade of the wet method is the application of the plaster layer. For the organization of the thermal insulation layer using a variety of techniques of decorative finishes, the main ones discussed below.

Mineral plaster. The material is a linking mixture, the base is a Portland cement. The main advantage of this type of coating is in a high level of strength and vapor permeability. Finish this type are resistant to moisture, do not syreet and not destroyed. Next advantage is affordable price. By cons should include a narrow range of colors.

Silicate Plaster - mineral species, since it contains liquid glass. Well suited for decorating and aerated concrete Foam concrete walls, as well as for use in the wet facade technology, because it has a high level of water vapor permeability. Note, however, that before its application necessarily need to cover the surface layer of special primer.

Acrylic plaster basically comprises a resin in the form of an aqueous dispersion. Positive qualities of the material are to a high degree of elasticity and adhesion with respect to different surfaces. To prevent cracking of the thin layer of acrylic is applied to the reinforced fiberglass mesh treated with sealant.

Silicone plaster has a number of unique properties, it is very flexible and malleable. Even in the case of subsidence of the building wall covered with a silicone layer is not cracked. This finish is presented in a variety of colors and has a self-cleaning property. Thus, the wall itself under the influence of rain will be cleaned from dust and dirt.

The basis of the wet facade: materials for work

Having examined in detail all the stages of the work, the novice master will be able to assess their strength in terms of the independent device with wet facade insulation. If a positive decision, you should take care of the presence of a full arsenal of materials and tools. The following list will take into account all the details. So, this technology requires the presence of basic materials:

1. Insulating panels as the base material requires a special approach in the selection. It is to calculate in advance the thickness of slabs of which the degree of insulation depends, and to study the characteristics of various heaters.
2. Plinth profile is selected taking into account the width and thickness of the chosen insulation boards. Number is calculated from the size of the building.
3. Grid for wet facade, which serves as a strengthening of the whole structure, most often a glass fiber web material. For buildings with a large load using a more robust grid.
4. Adhesive is applied to the wet fixing facade panels. His selected according to the selected heater.
5. Decorative plaster is applied at the final stage. You can use ready-made formulations.

Useful advice! The choice of materials for manufacturing wet facade primarily guided qualities and characteristics matched insulation. For example, mineral wool for the glue for fixing the foam plates and vice versa.

Additional materials for wet facade with their hands

The above list of materials considered to be the main, but not exhaustive. If you do not take care of the full set of purchase, before making a wet facade, there may be a number of disadvantages and difficulties in the implementation of the project.

The primer is applied in the preparatory phase with the aim of providing better grip slabs and walls. primer type is selected according to the kind of plaster.

Composition for plastering and reinforced protective layer is applied directly on the heater, although it is often confused with decorative plaster. These are different compounds - and this should be taken into account. One major difference - a higher price for the plaster finish.

The paint is designed for decorating the walls and serves as some protection against weathering. Do not neglect this material and save it.

Necessary component parts are mushroom-shaped anchors. It would seem a trifle, but without them it is not a reliable fixation of the plates will be provided. Therefore, their acquisition should take care in advance.

Dowels for fixing the plinth - a separate element, it is very important even in the preparatory phase. The length of the dowel-nails depending from the wall material, which is fixed profile. In the process of mounting the cap should also take care of the presence of specific elements to connect in places of bends and corners.

In order to purchase a complete set of manufacturers offer complete systems, which already includes all the necessary materials and tools to create a wet facade. At the same time, not every set takes into account the individual needs of the owners, in this connection with the purchase of such units need to be careful.

The tools needed to insulate the walls wet facade

List of tools to perform the work on the wet facade technology to include virtually the whole arsenal of an experienced builder and a number of special devices which will greatly facilitate and accelerate the process. In particular, you will need:

• angle required for marking of right angles and angles of 45 °;
• building level for determining the degree of deviations from the details of surfaces in a horizontal or vertical direction;
• measuring tape for measuring the length and width of the various materials;
• metalwork hammer designed to work with different materials;
• a fine-toothed saw for cutting materials of plastic foam;
• building a mixer for mixing dry building mixes sand, plaster, glue, putty;
• rollers to perform at various stages of primer and topcoat for coloring decorative plaster;
• Swiss trowels used for coating surfaces by different mixtures and their smoothing;
• serrated trowel applied for gluing and fixation method "vtaplivaniya" reinforcing layer;

• Easy ironing plastic, for applying bonding agents and plaster formulations;
• trowel for convenient mixing the solution;
• spatulas and trowels different sizes;
• cutter to deepen the anchors when fixing boards to the wall;
• sealant gun.

Useful advice! On the acquisition of the tools necessary to take care even at the preparatory stage. The list is extensive, and the maximum, but it is possible that in the course of work may require additional tools.

Insulation for wet facade: A variety of materials and features a selection

Facade insulation materials are divided into two large groups - products from expanded polystyrene and mineral wool. Foam materials are easy, quick installation and a high level of thermal protection. The main drawback of the material - its flammability. Mineral wool for wet facade is worth much more expensive, being a more reliable in its performance. Slabs of this material does not burn, have a high level of water vapor permeability.

mineral wool for the façade wet density should be not less than 150 kg / m³ and tensile strength - at least 15 kPa. Preference in the selection is recommended to give slabs of basalt fiber. As for the foam, it works for insulating material should be chosen for special purposes with poor combustibility. Experts in the art is advised not to use extruded polystyrene sphere having a low vapor permeable characteristics and having a weak adhesion with an adhesive solution.

In different conditions apply various kinds of insulating boards. In choosing guided physical and chemical characteristics of the heater, based on its particular destination. Each group has its insulation classification.

Mineral wool under the wet facade: Making materials and their benefits

Thus, mineral wool boards are ideally suited for facades. This advantage is due to a number of specific positive characteristics:

• durability;

• fire resistance;
• excellent water vapor permeability;
• a high level of thermal and acoustic insulation;
• resistant to chemical and biological agents;
• environmental friendliness;
• ease of installation.

In addition, certain types of wool, in particular on products of phenolic binders have a high level of water resistance. Most preferred considered slab of diabase or basalt wool wet facade. The price of such insulation is significantly superior to other peers, but this is the case when it is paid for quality.

Since Mingwu strength you should start from 15 kPa, and the material must not react with the plaster, the use in this field plates fiberglass impractical. This is due to the fact that this mineral wool is easily destroyed in an alkaline environment, and does not have sufficient strength to rupture.

Fiberglass boards will crumble under the influence of alkalis contained in the base layer and the reinforced adhesive solution. PH level of these materials is on the average 12.5. The corresponding reaction begins immediately, but after a couple of years. Destruction is particularly intense under the influence of strong winds. Thus, very quickly wet facade fiberglass panels will become worthless.

Additional quality as the criteria for the selection of the mineral insulation under wet facade

An important indicator in the selection of insulation boards is the coefficient of moisture absorption. Desirably, the level was at around 15% as moisture, soaked into the material will cause it inevitable deformation and negatively affect the thermal conductivity. Plates with a high degree of moisture absorption does not provide the required level of solidity facade. As a result, such an arrangement does not serve more than two years.

Useful advice!Indicator wet density mineral wool façade should range from 150 to 180 kg / m³. Otherwise, the complicated process of applying the finishing layer and there is a risk of delamination in all shielding facade.

wet facade technology involves selection of mineral wool slabs so that the degree of vapor permeability of the first (preparatory) to the last (decorative) layer is gradually increased. Compliance with this requirement will provide favorable conditions and prevent condensation occurs in the middle of the structure. The climatic conditions of Russia most of the time during the year the temperature readings inside the houses is much higher than outside. These conditions significantly increase the probability of occurrence of condensate.

Wet facade of foam: the material characteristics and the requirements for his or her choice

Determining the list has positive qualities and another group of heaters, the main raw material in the production of which is polystyrene. It should be noted:

• low cost;
• ease of material;
• high thermal and acoustic insulation;
• water vapor permeability;
• environmental friendliness;
• ease of installation.

Enumeration drawbacks foam slabs significantly exceeds similar characteristics of mineral wool. The main disadvantage - the flammability of the material. In order to eliminate defects of insulation manufacturers treated with special chemical means - retardants. Thus, even in case of fire, fire spread is suspended, i.e. the flame itself may attenuate.

Fire also provide special inserts of non-combustible materials, particularly of mineral wool. Use of this method has led to the appearance of a single composite material.

Among other drawbacks material - low degree of biosecurity. The foam can live insects and even rodents. Also, polystyrene foam boards are more fragile, which creates some problems during installation, and less wear in operation.

foamed polystyrene boards to the requirements for wet facade: price and quality

Before you buy the material for wet facade of styrofoam, should examine its performance and compliance with all requirements. It should have a tensile strength of at least 100 KPa and have a density of 15 to 25 kg / m³.

Useful advice! The choice of material in accordance with all the requirements for it and its proper installation at the exact compliance wet facade of a heater device technology guarantee its service life for 20-30 years. Repair decorative layer will have to make a little more often, but the costs will be much less.

Quality material can be determined even by external data. Granules insulation should fit snugly as possible to each other and have approximately the same size. Otherwise, such a foam will bring a maximum of problems, starting with the installation process and ending with the immediate operation. Poor coarse material absorbs an increased amount of moisture, which in turn, entails its deformation and results in a loss of thermal insulation qualities and premature destruction facade

Form of insulation boards from expanded polystyrene should be the same as that of a regular rectangle. Deviation is permitted not more than 2 mm per 1 m. Differences in the thickness of insulation can be a maximum of 1 mm, and the deflection of the front surface of the plane should not exceed 0.5%. Otherwise, it is impossible to produce a defect-free insulation facade of the house. Wet facade will be on the outside have a low aesthetic characteristics and its service life will be reduced by several times.

Consumption of materials everything for wet facade: a photo of private homes

As for other types of construction works, material consumption made roughly based on the required number of at 1m²gotovogo wet facade. Insulation of the house from the outside requires the following costs:

• primer required about 250 ml per 1 m²;
• adhesive for fixing insulation boards spent rate of 10 kg per 1 m²;
• Consumption of the insulation plate with a thickness of at least 5 cm corresponding to insulate the area;
• dowels for fixing the plates will need about 5 per 1 m²;
• Net wet facade is consumed at the rate of 1.3 m² per 1 m²;
• plasters for leveling layer should purchase based on the needs of 0.3 kg per 1 m²;

• primer consumption under the finishing layer is approximately 0.3 kg per 1m²;
• finished plaster takes about 3 kg per 1 m.

In order to properly calculate the required amount of material must be guided by the instructions on the packaging material, and it is better to buy ready-made kits. In this segment of the market is well proven system Wet facade Ceresit. Technology using façade insulation boards of mineral wool involves the use of brand Ceresit WM.

For warming with foam on wet facade Ceresit technology is marked VWS. Plates treated for thermal insulation of the adhesive composition and fixed to the wall, top coated with special protective layer reinforced with fiberglass. System suitable type contains all the necessary materials.

The components of the device wet facade price per m²

Price finished the wet facade includes the total cost of preparation, installation and decorative works. The main costs fall to the materials on the basis of their cost per 1 m² for a blank wall.

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

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

• the adhesive composition for securing a heater;
• plaster for foundations;
• mixture of plaster;
• grids for reinforced fiberglass layer;
• plugs and other fasteners;
• two types of primers;
• insulation boards.

Complete systems typically do not account for the cost of additional and optional components, various profiles and auxiliary fasteners. Also, not all manufacturers offer the complex thermal insulation materials. In this case, it should be borne in mind the average cost of insulation. For example, the average price of mineral wool for the façade wet thickness of 10 cm is about 650 rubles. 1 m². The cost of polystyrene in the same indicators – about 250 rubles.

Thus, the price per m² of wet facade with slabs of mineral wool will be about 1,200 rubles. Thermal insulation system of polystyrene much cheaper - about 750 rubles. 1 m².

Improvement of wet facade: the cost of labor for m²to order

Total costs for the installation of insulation and decoration include fees craftsmen or contractors. This is the case if the work is not carried out independently. Total price ranges from 1000 to 2500 rubles per square meter. Everything depends on the total amount of work, type of material and the method of decoration of the finished wall. The main components and the average price of wet facade installation are shown in the table below:

Type of work performed	Cost, rub. / M²
Installation and dismantling of scaffolding for construction	130 – 150
Priming the surface with the depth of penetration	60 – 90
Fixing insulation adhesive composition and alignment of the walls	370 – 450
Mounting of the reinforcing layer to the base plaster layer and embedded flush	330 – 370
Primer wall using quartz sand	65 – 75
Decorative plastering of various types	240 – 350
Decoration stone on the facade plinth	870 – 920

A wide range of prices of wet plaster facade is justified by varying degrees of difficulty decorating process. The list may also include additional work such as assembling ornamental elements. Their cost is calculated individually and depends on the complexity.

Additional factors that influence the cost of the wet facade

The above services and their costs are not constant. The list can be much longer, and price increases due to the appearance of additional costs. Total price per m² wet facade turnkey depends on a number of additional factors. In particular, it should be noted:

• original appearance and structure of the facade;

• the presence of defects and damage;
• the level of complexity of work;
• the total number of openings for doors and windows, and their arrangement;
• the qualitative characteristics of materials and their number;
• the total amount of work.

Useful advice! cost calculation is made individually for each case. Sometimes, even when an identical statement of work and the same treatment area, the price may differ materially.

Thus, the total cost includes additional costs. For example, labor-intensive work at high altitude will require the installation of auxiliary installation of forests. The cost of rent depends on the height and length of use. Also note that high-altitude work are much more expensive, as it implies the presence of special skills and organization of insurance. On the formation of prices affect the costs associated with the delivery and the characteristics of the individual facades.

Installation of a wet system will cost an order of magnitude cheaper than equipping ventilated facadeBut the continued operation will cost more. Wet facade technology is typically used for thermal insulation of private houses and ventilated - for finishing larger buildings. What is the reason, we consider below.

Ventilated Facades: priceDictated by quality

Speaking about the scope of the method of wet facade, it is worth mentioning such features as limited resistance to temperature extremes. Based on years of research The European Association of thermal insulation systems, plaster type concluded that the technology is appropriate wet facade not in all climatic conditions.

Even the most robust and expensive materials, assembling in compliance with all the requirements do not give long-term guarantees service in terms of climate inland temperate latitudes, which dominates large parts of the Russia. As a starting point the permissible use of the wet facade systems scientists Association took the grapes, or rather not the plant itself, and the cycle of maturation. That is, in an area where climatic conditions allow the maturation of at least one of its varieties, the use of technology is appropriate.

Under constant rain and high humidity, e.g., in close proximity to the sea, application of this technology is not desirable. This is due to poor moisture resistance of this type of facade. If the wall is subjected to frequent mechanical stress, the wet facade installation is also not recommended.

Based on these contraindications, facade alternative technology has been invented in plaster type of insulating curtain system with an air gap. Simply put - ventilated facade. What are the similarities, differences and advantages of this type of thermal insulation of buildings - will understand further.

Useful advice! Check quality of insulation under wet and ventilated façade by using the thermal imager. Warm colors in the photo shows the loss of heat, and the dark - temperature resistant walls.

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

Hinged system differs from the plaster so that during assembly of the facade wet plaster is applied directly on a layer of insulation. Ventilated facade involves the installation of a front panel of fiber cement at a certain distance from the heater, that provides the necessary protection from atmospheric precipitation. In addition, thanks to the protective screen excessive moisture, which appeared for the facade panel, can evaporate through the air opening.

Thus, Ventilated facade has the additional, compared to the wet process, and provides a number of functions:

• additional protection against moisture and sound insulation;
• highest degree of protection against ignition;
• cool room in the summer, allowing you to save on air conditioning;
• elimination of defects on the wall in the form of irregularities and distortions;
• ease and speed of assembly;
• a wide range of design options;
• additional insulation, which contributes to the presence of the air cushion.

In addition, the coating of fiber cement does not require support services and maintenance of the decorative layer within a few years. Suspended design can serve without intervention decades.

Solving the dilemma of how to choose the facade, you can be guided by the following recommendations. Wet facade is appropriate when you need to minimize the costs to finish the building and minimize the load on the wall. In this way it is possible to draw perfectly smooth walls, without complying with specific requirements for strength and wear resistance of the facade.

Curtain lining, in turn, compensates for uneven walls and helps to hide any defects. Works on installation of the ventilation of the facade can be done at any time of the year, even at temperatures below freezing.

Areas of application of the device and wet the facade ventilated facade

Scope of ventilated facades are much wider. They are used for thermal insulation of private houses, multi-storey buildings and decoration of public buildings. The most widely used for the decoration of shops, cafes, shopping centers and other public and commercial establishments.

Important! Wet facades are used for thermal insulation of buildings with low floor and outbuildings, as well as in case of the need to save on a heater. As a budget option for this method can be used in the system power-saving state institutions and public buildings.

The ventilated façade wall using different materials, in particular:

• Porcelain plates;
• panel made of aluminum and composite;
• fiber cement;
• laminate plate produced under high pressure.

The main advantages of stoneware facade are its strength, various colors and high aesthetic characteristics. But there is such a material is rather expensive. The price of aluminum composite panel more democratic. The material itself is generic, and thanks to the wide range of colors and textures allows you to realize the most daring imagination of the architect.

Fiber cement - a material that imitates stone, resistant to moisture and sun. Installation is simple and open-type fastening. His more often used for facing houses. Laminated panel - a new material having a variety of colors, texture, resistant to weathering and fire, it is lightweight, durable and eco-friendly. In addition, it is cheaper than porcelain stoneware analogues.

wet facade technology for mineral wool: instructions, Tips and secrets of the masters

If, after considering all possible options for warming the choice was made in favor of the wet facade with tiles mineral wool and work decided to produce its own, it is necessary to take into account a number of secrets masters.

You should start with the choice of material. Thus, the special literature and on the Internet you can find recommendation for the replacement of mineral wool in the glass. This is misleading, since the glass fiber plate eventually begin to sag under the vibrating influences and insulating layer are formed so-called cold track.

For maximum thermal insulation effect should take care of the warming not only the facade, but also the floor and ceiling. In particular, this applies to apartments above unheated rooms or on the upper floors.

With proper selection of mothers and strict adherence to the instructions the warranty period facade service can reach the half-century mark. Additional protection topcoat plaster coating will provide a special paint, which also extend its life. For this purpose, you should use latex paint with acrylic, silicone and silicate impurities. Its color variety includes more than a thousand shades.

Useful advice!During the painting should look into the construction documents, which indicated the original color of construction - a new shade should match it.

Conditions for successful installation of insulation technology wet facade: video recommendations

Warming of the wet technology should take place under conditions of full protection from the cold and rain. If the work does not require a delay, and its completion occurs in adverse conditions, it is necessary to take care of the construction special scaffolding and cover them with a dense film, which will provide temporary protection from wind and moisture and create little heat circuit.

Before starting work on the installation of wet facade is necessary to tightly close all access to the interior of the room from the windows and doors. All internal rough work in the house is better to finish before the warming. On the wall outside should advance to place a number of mounts and brackets that will hold air conditioners, cameras, sills or gutters.

With the adhesive solution should work in the shade or at elevated cloud maximally eliminating sunlight onto the mixture. The distance between the plates and the insulation reinforcing mesh should be at least 2 mm, which provides a pouring of adhesive.

For a general sandwich structure strength to dry each layer is required to give a few days. Haste in this case is unacceptable. The performance characteristics depend on the plaster of the work conditions. Optimum conditions - a temperature over 5 ° C, increased cloudiness, dry, windless weather.

Plastering materials must be selected exclusively for outdoor use, which can fully resist the negative influences. The upper plaster layer must have high thermal conductivity and moisture resistance to be durable and resistant to mechanical, chemical and weather resistance.

House warming wet facade: summarizing

Technology Wet facade, though inferior in a number of operational characteristics of ventilated facades, is the leader among the existing methods of insulation. Its advantages lie in the application of modern high-quality thermal insulation materials, the service life of some of them may reach half a century. A special external finishing with high aesthetic characteristics not only guarantees outer beauty modern houses, but also makes the valid technology in architectural restoration attractions.

To achieve the best results you need to trust the certified companies, as well as use of high quality materials manufacturers, well-established in the construction market. To prevent the occurrence of chemical reactions, it should be noted that the individual components must be compatible with each other. Each subsequent layer must have an elevated level of vapor permeability relative to the previous. Do not forget about the strength and density of the materials and their compliance with fire and environmental requirements.

The design is intended to provide a high degree zvukozaschity in two directions (both inside and outside the home). The quality of materials affect the longer-term operation not only the insulation layer but also the entire house, protecting the walls from rain and mechanical damage. Facade closes the main structure of the wind effects of frost, dirt, moisture and ultraviolet light.

In conclusion, it should be noted that the use of a variety of choices of decorative plaster in the wet facade system, decorations and color schemes It allows to realize on the outside of the building different stylistic ideas, which can not be done using other methods of insulation, such as ventilated technology facade.
