Ceresit façade insulation system technological map. Wet facade technology - ceresite: its features, advantages and installation method

Insulation technology facades Ceresit is a closed system with thin layer protective plaster on top of the thermal insulation layer. The insulation is attached to the outside of the building with cement adhesive solutions, then a thin but durable material is made from the solutions on the surface of the insulation protective layer, reinforced with fiberglass mesh. and finally, the decorative finishing of the facade is carried out thin-layer plasters. You can find out more about the installation stages on the Work Stages page.

Ceresit systems can be used both on large construction sites and in small cottage construction.
The main difference between Ceresit insulation systems is the type of insulation used in their construction: expanded polystyrene or mineral wool.

VWS system

Facade insulation system based on polystyrene foam (foam plastic)

The Ceresit VWS system uses expanded polystyrene boards as insulation. Expanded polystyrene differs from mineral wool board in its more affordable cost and lighter weight (5-7 times lighter).
However, expanded polystyrene is characterized by low vapor permeability and creates great resistance to the penetration of water vapor. This means that the vapor content in the wall of the building will be slightly higher, which will create conditions for its humidification. But since the “dew point” is located in the insulation, condensation will not form in the wall.
If there is sufficient ventilation in the premises and there is no excess humidity(as, for example, in baths and swimming pools), then no problem arises. At the same time, the vapor permeability of finishing materials does not play a significant role - finishing of facades insulated with polystyrene foam can be done with both mineral and polymer materials.


ADVANTAGES
1. Does not lose its thermal insulation properties when exposed to moisture
2. Does not contain substances harmful to health
3. Very light and has good strength characteristics (Tensile strength is about 80 kPa, compressive strength is about 130 kPa. The stress at 10% compression of polystyrene foam is about 80 kPa)
4. More technologically advanced due to strength characteristics
FLAWS
1. Low coefficient of vapor permeability
2. Low sound insulation properties
3. Not resistant to most organic solvents

WM system

Mineral wool façade insulation system

The Ceresit WM system uses mineral wool boards as insulation. Mineral wool board has two main advantages over expanded polystyrene: non-flammability and high vapor permeability.
In construction, water has always been enemy number one, contributing to both the destruction of structures and the deterioration of their thermal insulation. Excess moisture must be removed from the building, since dryness means warmth and strength.

Minslab has little resistance to water vapor. They easily penetrate the building envelope, and condensation is effectively removed, so the building “breathes.” Wherein Decoration Materials must also have high vapor permeability. Therefore, when insulating a façade with a mineral slab, finishing can only be done with mineral plasters or polymer plasters with high vapor permeability.

You can get a detailed description of the installation stages of facade insulation systems by downloading the “Installation Instructions” or in the “Installation” section.
4. Resistant to most chemicals
5. Good sound insulation properties due to the fibrous structure mineral wool
6. Suitable for any wall base
FLAWS
1. Heavy material
2. Relatively high cost
Components of this system


IN Lately The Ceresit insulation system, which is installed using the “wet” method, is becoming increasingly popular. The manufacturing company has made a significant contribution to this area.

Each of the components of the system, including glue, insulation, primer, plaster, as well as other components, can effectively interact in one ensemble.

Moreover, each component complements the others. Recommended for arrangement facade system use components produced by the same manufacturer.

Otherwise, a mismatch between the components may occur, and the final assigned tasks will not be completed.

The Ceresit plaster facade has undergone many tests in the harsh Russian climate.
This insulation system not only protects the building from the cold, but also gives its facade an excellent appearance and aesthetic appeal.

The installation of the Ceresit façade system involves several stages.

At the initial stage it is necessary to produce preparatory work the base of the walls, this involves analyzing the condition of the facade and basement of the building. This will allow you to determine if there is damage or unevenness on the walls.

During the work it is necessary to strengthen thermal insulation boards, where Ceresit ST85 brand glue should be used.

The façade insulation system in this case requires complete drying of the adhesive, which will take 3 days, only after which additional fixation can begin facade slabs. Dowels and washers should be used at this stage.

Arrangement of facades when attaching insulation requires the formation of holes intended for dowels; this should be done extremely carefully, which will prevent damage to the surface of the heat insulator.

The next layer will be a reinforcing mesh on which the waterproofing is laid. In order to provide additional strength to the system, fiberglass mesh should be laid on top.

After 3 days, you can start carrying out finishing works, which involves covering the surface with plaster. It is preferable to equip a wet façade using mineral, silicone or polymer plasters brand Ceresit, this will be the optimal solution.

Tools and materials

  • plastic grater;
  • steel grater;
  • grater;
  • glue;
  • insulation;
  • dowels with washers;
  • reinforcing mesh;
  • waterproofing;
  • putty;
  • primer;
  • base profile;
  • mineral wool slabs;
  • facade paint;
  • brush.

Preparatory work before starting the installation of the system and strengthening the insulation

The installation of Ceresit facades involves the removal of the previous cladding if its stability is questionable and it has poor adhesion to the walls.

System wet facade before further work may require leveling, during which you can use façade putty brand Ceresit ST 29.

This composition must be applied to surfaces that are pre-treated; for this, a façade primer of the Ceresit ST 17 brand must be used.

Then, in the area of ​​​​the border that connects the base and the facade, along the entire perimeter of the building, it is necessary to strengthen the base profile, which will determine the starting point for installing the insulation slabs.

Afterwards, a heat insulator must be strengthened onto the surface of the facades; they can be slabs of expanded polystyrene or mineral wool.

They are perfectly fixed on the walls with adhesive mixtures of the ST 85 or ST 190 brands, produced by the manufacturer Ceresit. Can also be used polyurethane glue brand ST 84, which is sold in cylinders.

The peculiarity of the technology at this stage is that polystyrene foam insulation should be applied to the surface of the slab glue mixture, in this case it is necessary to form a strip, the width of which should be 6 cm, while its height should be 2 cm.

The composition should be applied along the perimeter of the base, 2 cm away from the edges. The mixture should be applied in the central part of the slab like beacons, the diameter of each of which should be 10 cm and the height 2 cm.

The maximum number of such beacons should be 8 pieces.

If the insulation process is to be carried out using mineral wool slabs, then the adhesive mixture should be applied in a continuous layer.
Once the glue has been applied and distributed, the slab can be applied to the wall and pressed. At the stage of strengthening the insulation, the Ceresit system should be built from the base profile; the material should be laid in order, moving upward.

Do not forget that during the installation of insulation, its position should be controlled using a level. Now you should wait until the glue hardens, only after, in order not to change the position of the plates occupied by them during the fastening process, you can grind the base using a polisher equipped with coarse sandpaper.

Then the insulation can be further strengthened, as described above.

Installation of the reinforcing layer

On next stage When arranging Ceresit facades, a waterproofing mixture should be applied to the surface of the insulation; when using polystyrene foam heat insulator, the ST 85 mixture from Ceresit is used; when using mineral wool, waterproofing ST 190 is suitable. The mixture solution should be applied to the base in a layer of 3 mm.

The reinforcing mesh should be laid on the freshly applied mortar and recessed into it with a trowel. Arranging a wet facade requires laying a mesh with an overlap, which can vary from 5 to 10 cm.

During this process, the mesh does not need to be stretched too much and deepened all the way to the heat insulator. Then the façade system must be equipped with a layer of mortar, the thickness of which must be 2 mm.

The mixture should be applied so that the mesh is hidden underneath. And then the surface should be leveled using a metal grater.

Arrangement of the decorative layer

The process of insulating facades using the Ceresit system involves last stage applying the finishing decorative layer.

To ensure better adhesion of the reinforcing and decorative layers, priming should be done. Can be used as a primer solution facade paint brand ST 16, the color of which is close to the color facade plaster. It should be applied as evenly as possible, using a brush; one layer will be enough.

When constructing a plaster facade using a silicone or silicate mixture, you should use a primer of the ST 15 silicon or ST 15 brand in tandem.

Thin layer plaster mixture should be applied to the surface as evenly as possible, the thickness of the layer should be equal to the thickness of the grain, in this case it is worth using a polisher, the tool must be held at a slight angle, after which the surface must be further smoothed.

After the facade plaster stops sticking to the tool, it can be given the desired texture using a plastic trowel, which must be held in a horizontal position.

Creation of plaster facades with different textures

In order to obtain a layer based on plaster that will have a “bark beetle” texture, mixtures of grade ST 35 and ST 75 should be used, the grain diameter should be equal to 3.5 mm.

The composition of the ST 73 brand is also suitable; its grain should be equal to 2 mm in diameter. You can get the desired texture by rubbing the surface with a plastic polisher, which should be moved in one direction, as a rule, it is horizontal or vertical, less often circular.

To obtain “pebble” textures, you can purchase facade plaster of the ST 73, ST 75 or ST 137 brands, the grain diameter of which should be 1.5 mm.

A mixture of grade ST 137, the grain size of which is 2.5 mm, can also achieve a pebble effect. Grouting should be done using the same tool.

In addition to those described, you can create a mosaic-type texture; a mixture of ST 77, which has different grain diameters, is suitable for it. Silicate, acrylic or silicone paint from Ceresit will allow you to obtain a certain shade of the surface.

Features of Ceresit facade plasters

Plasters produced by the manufacturer Ceresit can have different designs: acrylic, silicone, silicate, mineral and all kinds of combinations thereof.

Each of them is characterized by its own protective properties. Taking into account certain coating requirements, it is possible to select suitable option. So, if you want to avoid replacing the coating for a long time, you should choose silicone or mineral mixtures.

They are also characterized by good vapor permeability. If you primarily want to solve the issues of resistance to rot and sunlight, you should choose acrylic mixtures.

When choosing one or another mixture, you should take into account that facade plaster can give the facade the desired appearance. This can be achieved by painting the surface or by using a certain structure of the mixture, which is determined by the grain size.

The standard range of colors is limited to 163 shades. However, each client can make individual order, then the choice expands to 2,000. The manufacturer achieves this by mixing dyes and using different tints.

Insulation of facades with plaster from the manufacturer Ceresit guarantees mechanical strength coverings. For comparison, if panels made of plastic are not able to withstand strong mechanical stress and require additional protection in the form of a fence, the described plaster will not be damaged.

You can be sure of its environmental friendliness and fire safety. These characteristics can make plaster stand out among materials such as plastic or wood. This allows the plaster to act as additional protection for the entire house.

If you want to know what the consumption of facade plaster is, it will depend on several factors, among them: the type of surface to be finished (the complexity of the architectural solution and material), the type of composition applied and the grain size.

In the instructions for use this indicator is indicated different sizes and is recommended. For a mixture whose grain is 1.5 mm, the consumption of the plaster composition can vary from 2 to 2.5 kg/m2; for a composition with grain with a diameter of 2.5 mm, the flow rate can be increased to 4-4.5 kg/m2.

If you decide to use a structural mixture, the consumption can reach 5 kg/m2, however, the material consumption in this case will depend on the formation of the texture. If the composition has marble chips, the consumption will increase and be equal to 5.2 kg/m 2.

And if you want to ensure a more rational consumption of the mixture, you should prefer silicone compounds.

Buyers choose these compounds due to the fact that such insulation arrangement is considered budget option home decoration.

However, preparation of the walls requires attention Special attention This will be the main difficulty of carrying out the work; you will have to get rid of old coatings that do not hold up well.

But there is an opportunity to save time and labor costs for the fact that you don’t have to arrange load-bearing frame. It is preferable to start work with back side buildings, which will allow you to gain skills without spoiling the visible part of the facade.

Many people also appreciate the fact that no construction garbage, the removal of which also involves certain costs.

There is no need to prepare the material before starting insulation; you can deliver it yourself, without involving professional automotive equipment.

The cost of plaster will depend on the type chosen, on average 1 m2 will cost 50 rubles, and the total cost of surface preparation work, taking into account additional materials will start from 250 rubles/m2.

It has properties that prevent external influences, and also add decorativeness to the facade along with protecting the walls.

The modern market is rich in high-tech facade plastering products: these include facade plaster from various manufacturers, including Ceresit mixture.

This manufacturer meets all the requirements for façade coating. Ceresit is represented by a company that has been producing products for construction and finishing for decades.

Production plants decorative plaster Ceresite is found in many countries, including Russia, which indicates the demand for the material, and, accordingly, about high quality products. In addition, the technology for producing facade mixtures is slightly different from analogues.

Ceresite consists of high-tech constituent substances, which endow the material with appropriate qualities. A large assortment products will help you decide on the choice of material. The material is presented by the manufacturer in different texture options, with different composition(depending on the purpose).

Variety of colors and textures

Advantages

Ceresit is widely used precisely because of its positive characteristics:

  • high elasticity (the material contains components that enhance the elasticity and viscosity of the material);
  • ease of application(standard application with a spatula does not differ from similar work with other mixtures);
  • creates an impact-resistant coating (mechanical stability guaranteed by the manufacturer);
  • resistance to fading (even the colored mixture does not fade when exposed to ultraviolet rays);
  • the material is durable (operational properties last for more than 30 years);
  • environmental friendliness (plaster does not contain harmful substances);
  • moisture resistance (the coating repels water and prevents its penetration into the surface);
  • resistance to pollution;
  • resistance to temperature changes;
  • variety of colors and shades.

Color solutions

In addition, the material has good adhesive properties, which allows it to be used on different surfaces. Classification according to use in cold and warm seasons also helps with selection, especially when performing work in the cold season.

Flaws

No technical deficiencies were found in this mixture: the material has proven itself as quality product. If we can call the high price (compared to analogues) a disadvantage, then this is the only thing that does not always suit the buyer. The price is consistent with the quality, so if you pay a little more, you can feel complete satisfaction from the quality of the product.

Technical characteristics of Ceresit plaster

Ceresit is a certified product; facade mixtures (for example Decor Plus) meet the required quality criteria and have the following technical characteristics:

  • density - 1.7 kg per dm³;
  • application temperature - from +5°C to +30°C;
  • time for drying the layer before texture formation - up to 15 minutes;
  • resistance to moisture (rain) - after 24 - 48 hours;
  • consumption - from 2.5 kg/m² to 2.7 kg/m² (for 2 mm grain), from 3.5 to 3.8 kg/m² (for 3 mm grain).

The plaster has persistent hydrophobic properties, low water absorption, and resistance to pollution.

NOTE!

The mixture should not be frozen, but open packaging should be used as quickly as possible and stored tightly closed.

Specifications

How does Ceresit plaster stand out among its competitors?

To create a decorative outer covering, facade plaster with a grooved structure: this mixture is excellent for concrete surfaces, gypsum, sand, cement.

This feature allows you to use this facade material on any surfaces while maintaining texture.

Due to the composition of the plaster, its elasticity is especially noticeable compared to other mixtures.. In addition, this coating does not fade and is mechanically stable.

If we consider the products of other manufacturers, not all of them have a division of mixtures into summer and. The issue of choosing this parameter is especially relevant when working at non-traditional times for repair work: in winter or cold spring or autumn.

Types of Ceresit plaster

High-quality Ceresit coatings are classified according to their composition:

  • . Designed to perform finishing. The composition prevents the appearance of fungi, masks small cracks, applies to expensive mixtures;
  • . They are able to hide defects on the surface, are not vapor-tight, have a smooth texture, and have increased strength indicators;
  • . Due to the presence of cement in the mixture, this coating is durable, breathable, elastic, and easy to apply;
  • . The main component of the mixture is silicate resin. These mixtures have elasticity, special strength, and are most often used for interior works(in rooms with high humidity), as well as for outdoor work;
  • . Used for external coating of facades.

Comparison of species

In addition, Ceresit compositions are made for subsequent painting or for finishing coating without painting.

Facade mixtures are divided into “winter” (they can be worked with at temperatures below 0°C) and “summer” (for work in hot weather).

Textures of Ceresit plaster

Ceresit compositions have two textured patterns, the texture of which is achieved due to the presence of granules in the composition and through a certain application:

  • . This texture should be applied in a thin layer. Due to availability large quantity When applied, the grains in its composition form a peculiar pattern. Suitable for outdoor and outdoor use;
  • "lamb". Thanks to the special texture of the “lamb”, it effectively hides flaws or unevenness of the walls, which subsequently acquire a different, improved look.

Types of textures

Any invoice can be presented in different colors, and if necessary, it can be additionally painted. For painting, it is advisable to use Ceresit paints, which may contain acrylic, silicate or silicone components.

How to properly prepare the mixture

To prepare the mixture, you must have a container (bucket) for mixing it (use only stainless steel utensils). The manufacturer most often produces plaster in 25 kg bags.

For correct calculation required quantity mixtures, it should be taken into account that The recommended mixture consumption per 1 m² is from 2.5 kg to 4 kg.

For 5-6 liters of water you need to add 25 kg (bag) of dry composition. Cold water must be used.

The plaster should be mixed with a mixer or concrete mixer.

The mixture is left for three minutes to completely dissolve, and then it should be mixed again.

The prepared mixture should be used within three hours.

The frozen mixture cannot be used.

Mixture finishing technology

Before applying the Ceresit mixture, you should prepare the base for finishing:

  • clean the surface of other coatings, sand, debris;
  • Level (if necessary) the entire base.

The boundary between the façade surface and the foundation is covered with a plinth profile before covering it with façade plaster.

Before applying facade plaster, a reinforcing layer should be applied:

  • use a layer of Ceresit waterproofing mixture with a thickness of 2 mm to 3 mm;
  • lay it so that it drowns in the mixture;
  • Next, you should apply another layer of solution to the mesh;
  • level the mixture and wait for it to dry.

Laying reinforcing mesh

To perform finishing with Ceresit plaster, you must follow the following steps:

  • the prepared surface should be treated with a primer: This must be done for better adhesion of the plaster to the wall. When working with Ceresit plaster, it is recommended to use a primer paint for facades from the same manufacturer with a similar color finish;
  • After applying a single layer of primer, apply plaster. To apply it, you should use a polisher;
  • The composition should be applied in a thin layer, which should correspond to the thickness of the grain;
  • when applied to small area the plaster should be leveled without waiting for it to dry;
  • to add texture, you should use a polyurethane float, which is used to treat the surface after it has stopped sticking.

Creating an invoice

To add texture, apply the plaster in a circular, horizontal manner, using a polyurethane polish.

Creating different textures

For the “bark beetle” texture, mixtures with grains up to 2 mm to 3.5 mm in diameter are used. In this case, the surface is rubbed with a polisher strictly either vertically or horizontally. The bark beetle is produced in white, so additional coloring is required.

NOTE!

When applying pebble structure plaster, various rollers are used, spatulas or graters and a mixture containing pebbles with a diameter of 1.5-2.5 mm.

Grouting plaster

Thus, Ceresit plaster is widely used thanks to quality composition, meeting high requirements for impact resistance, endurance, decorativeness, durability. These mixtures, despite the fact that their cost may be higher than competitors, are in great demand. A facade covered with such plaster will acquire individuality and will be effectively protected.

In contact with

A home that is pleasing to the eye from the outside and comfortable on the inside are signs of a good homeowner. The use of Ceresit wet facade technology allows you to achieve these qualities. The technique itself of such house insulation is well known, because it has a number of several advantages, against the background of which other options become less significant. Bringing beauty to the design of the house, the ability to retain approximately 30% of heat in cold seasons and others, no less significant factors, which popularize the “wet facade” technology.

Features of the technology

Before you get started, you need to consider a few points. Namely, how the components will be applied in the wet façade. There is no specific standard. But the budget option would be to use 4 main layers.

  1. The surface of the wall that serves as the basis for fastening other layers.
  2. Thermal insulator.
  3. Reinforcing gasket. It includes a special mesh and plaster.
  4. Decorative.

The point you need to focus your attention on is insulation. Because it greatly affects the comfort and coziness of the home.
Depending on what type of heat insulator is used, there are:

  • Wet façade based on mineral wool (Ceresit WM)
  • Wet facade using expanded polystyrene (Ceresit VWS)

Advantages of using the Ceresit façade system

It is important to know that plasters, adhesives and other components used in a system function most effectively when each of these building materials can complement each other. We can conclude that the ceresit facade system is one of the most effective, because all the necessary components are carefully selected for it.

The individual properties of each element are taken into account, the compatibility of each component with each other is checked, and all possible changes that may occur with the materials as they are used are carefully calculated. And all this is the reason that Russian tests facade insulation Ceresit were completed with good results.

useful in work

Despite all the harshness of the Russian climate, the system proved to be the best side, how in cold winter, and in cloudy, humid weather.

For example, Ceresit CT 190 is often used in such situations. The exclusive features of which are high adhesion, the possibility of application from -10C, the content of reinforcing microfibers, high strength and environmental safety.

The Ceresit facade system has sufficient versatility to give the appearance of a house a good look and at the same time, has the ability to be combined with neighboring architectural buildings.

Four stages of installation of the Ceresit facade system.

Let's look at each stage in more detail:

Preparing the walls.

Inspecting the condition of the facade, base and roof of the building is the responsibility of the specialists who will carry out the installation. During the inspection, all irregularities and defects in the walls are identified, after which a general assessment of the condition is made.

Installation of insulating boards.

The corner part of the house is the start of installation. The first layer is installed on a perforated profile. As a result, a certain protective belt appears around the entire building, the height of which is usually 250 mm and thickness from 40 to 80 mm.

Installation of reinforcing gasket.

The waterproofing is installed on the main layer of the slabs and their lower area. The reinforcing mesh is mounted on the waterproofing layer. After which another layer of waterproofing compound is reinstalled on the reinforcing mesh. In order to achieve greater security, a fiberglass mesh is used, which is mounted on all these layers. The profile is firmly installed in the waterproofing mixture, then putty is applied. The fiberglass mesh should overlap the profile by approximately 10-15 cm. The mesh is attached to the profile by operation special adhesives ceresite. Another layer of waterproofing, the thickness of which should not exceed 1.5 mm, is laid on top of the fiberglass mesh.

Facade finishing.

After three days after completion of all work, you can move on to the next step - finishing the facade. Using ceresit CT 16, the surface is coated with a primer. After 3-6 hours have passed, the decorative layer is installed. If the insulation material is mineral wool, then all elements used in the work must have vapor-tight properties. In such situations, the use of Ceresite plasters will be just right.

A few words about what is the normal temperature at which installation of thermal insulation is possible. Work should be carried out exclusively in dry weather and temperatures from -5C. Air humidity should not be higher than 80%. If the cold is short-lived, then after a certain time the work can be continued again, but it is worth considering that if you leave the insulation boards without a protective shell (from 2 to 3 weeks), this may adversely affect their quality. Therefore, it is necessary to carefully check their condition. If there are minor changes for the worse, such as yellowing of the slabs or excessive dust content, the surface must be cleaned using sandpaper.

Direct Sun rays, are one of the main enemies of new mounted layers. It is also worth mentioning increased moisture and wind. Metal sheets used as slopes and ebbs, along with construction mesh, the projections of which should not exceed 40-50 mm, act as an additional protector of the plaster. It is also worth considering that if the climatic conditions were difficult during work, then the drying speed of the finishing solution will be significantly lower. When preparing the mixture, it is recommended to adhere to the following rules:

  • Take elements contained in one batch;
  • uniform dosage of water taken from one source.

Let's summarize. The benefits of using “wet facade” technology

  1. Ability to build thin walls
  2. Material saving
  3. Building a foundation is one of the most expensive stages construction of a house, and the use of “wet facade” technology will avoid many troubles.

The Ceresit system for insulating facades provides reliable thermal insulation of the external walls of a building and protects against aggressive influences environment. The advantage of this solution is the lightness of the materials, the small thickness of the insulation, and ample opportunities decorative finishing.

There are two ways external thermal insulation: Ceresit VWS and Ceresit WM. The main difference lies in the application: it can be sheets of polystyrene foam or mineral wool boards. The versatility of this insulation allows the use of these thermal insulation methods in both private and large-scale construction.

This thermal insulation is closed system and consists of insulation, which is attached to the wall using adhesive mixtures. It is covered with a protective layer on top, including a fiberglass mesh frame. Decorative finishing completes the thermal insulation process.

Ceresite based on polystyrene is used in houses with a height of no more than 75 meters and which do not have increased fire safety requirements. PPS sheet is 5-7 times lighter than mineral wool slabs of similar size and is more affordable.

The PPS insulation method is reliable thermal insulation with the following advantages:

  • does not contain hazardous substances;
  • saves thermal insulation properties when moisturizing;
  • good strength characteristics allow us to recommend it as an easy-to-process building material;
  • the lightness of polystyrene foam is a significant advantage over analogues.

Application of teaching staff causes low vapor permeability, which prevents moisture vapor from entering the outer surface. This will increase the content of moisture vapor on the surface of the wall, but condensation occurs in the polystyrene foam itself due to the localization of the dew point there. As long as proper ventilation and normal moisture content in the air are ensured, there will be no operational difficulties.

Ceresit wm insulation systems based on mineral wool

Ceresit facades mounted from mineral wool slabs have high vapor permeability and are non-flammable. Such properties ensure the removal of condensate from the thermal insulation layer. Mineral wool helps good penetration through the enclosing structure of water vapor, due to which the building “breathes”. Ceresit facade insulation based on mineral wool slabs is an insulation system that has the following advantages:

  • naturalness - mineral wool is made from rocks;
  • versatility of use - suitable for installation on any type of wall;
  • has high sound insulation properties;
  • resistant to aggressive substances;
  • has high vapor permeability;
  • resistant to impact high temperatures– for the cotton wool to begin to melt, it will require exposure to a temperature of more than 10,000C for 120 minutes.

Ceresit for insulating facades, in which mineral wool is used, allows you to achieve excellent thermal insulation and sound insulation, and ensure high fire safety of buildings.

Flaws

Ceresite facade insulation has some disadvantages and limitations in application. So, PPP has the following restrictions:

  • susceptible to the action of organic solvents;
  • does not protect premises from extraneous sounds;
  • has a low coefficient of vapor permeability;
  • has limitations in use: applicable only for walls made of monolithic reinforced concrete and three-layer panels;
  • It is unacceptable to use in buildings with increased requirements for fire safety, for example, in hospitals.

U mineral wool slabs There are fewer disadvantages:

  • the material is heavy (22-40 kg/m2);
  • high cost of material;
  • low impact resistance.

This method of thermal insulation has universal application and is suitable for all types of walls.

Ceresit building thermal insulation technology has shown good performance and thermal insulation qualities, which allows us to recommend this method. The ability to choose the finish and color to your liking removes restrictions on the personal preferences of the owner of the house or apartment.
