Plaster as a way to protect and refuel the facade has a thousand-year history. In some cases unique effect The world fame and significance of the brand acquired, if we recall the Venetian plaster, imitating marble cladding.

But for any finishing layer of solution cement-sand mixture inevitable were cracks and collapsions detached fragments. Plaster mesh helped solve this problem.

What is the reinforcing grid?

Flexible, openwork, knitted or woven - it creates a monolithic framework frame.

The prototype of the plaster grid can be considered common method of lamb wall Under the stucco, with the help of thin narrow dugs, laid cross-stroke - the so-called "duncar". Until now, among the ruins of pre-revolutionary and Soviet buildings, you can see the naked skeleton of a wooden reinforcement.

The creation of new materials and construction technologies allowed replace time-consuming process The walls of the walls are very fragile wooden dranco on a fast and reliable way to strengthen rough plaster different species Facade mesh.

Does the grid in the plaster, its advantage:

1. Improving the effect of clutch of different materials.
2. Protection of excessive hygroscopic masonry material (aerated concrete) from moisture penetration.
3. Hardening corner elements and stakes of structures when removing window and doorways.
4. The formation of a monolithic frame that ensures the durability of the walls and the strength of the cladding.
5. Insurance from internal stress of walls with sudden drops of temperature and humidity.
6. Restoration of cracked fragments of the facade.
7. Reinforcement of waterproofing.
8. Achievement of a respectable type of finishing work.

What requirements presents to the GOST 3826-82 plaster grid:

• density in the range of 150-170g / m²;
• corrosion resistance and alkalis effects;
• low weight (not complicating building loading system);
• resistance to stretching with permissible flexibility and tensile strength;
• identity of cells (alternating and magnitude);
• the presence of accompanying documentation on tests conducted in independent laboratories.

Reference: The plaster grid is also successfully used in the preparation of screeds, fill the floors for the device "warm floor", when installing insulation of attic rooms and roofs.

How to produce?

Materials, as well as making methods, several.

Metal (sheet or wire):

• wicker from wire spirals (chain grid - by the name of the creator, German Karl Rabita Mason);
• woven The grid is created from wire threads along the type of weaving weave base and duck, allows the use of wire of any section, gives the product the necessary flexibility;
• welded - fixes the welding area of \u200b\u200bthe crossing of the wire, forming the cells of the square shape; Used to prevent wall shrinkage;
• twisted (Magnier) - wire twisted in such a way that forms 6 coal cells, the main advantage is the resistance to high T◦;
• non-exhaust (CPVS) - It turns out of sheet metal (thickness 0.5-1.0mm) by cutting under the press, which, when tension, form diamond cells, is most convenient for cutting and transportation.

Metal grid is worth choosing with galvanized coating or polymer spraying. So she will serve longer.

From polymers (plastic):

• armaflex (with enhanced nodes) - ultra-duty;
• plurima (with cells 5x6) - chemically inert;
• sintoflex. - with medium and large cells, lightweight, resistant to chemical exposure.

Universal (polyurethane) with cells of 3 species:

• small (6x6);
• middle (15x13);
• large (35x22).

Fiberglass - fine, ultra-durable, without restrictions in application. The grid is woven from fiberglass with other components and is impregnated with polymer solutions for the purchase of chemical resistance.

Fluster used for:

• strengthening the base layer;
• giving strength to finishing elements from soft materials;
• reinforcement base under the finishing trim tiles.

Important: Each type of grid is designed for a certain thickness of the plastering layer and features of operation. Incorrectly selected reinforcing layer can lead to cracks, irregularities, detachal of the entire coating together with the finish finish.

What mesh to choose?

Reinforcing grid N. cheap Material, but saves the cost of owner For subsequent repairs and restoration of lost fragments of the facade. Application of a plaster grid in the facade finish gives him representative view. Therefore, costs are justified.

But acquiring material it is necessary to make sure of his quality, what does it say:

• appearance products (identity of the size of the cells, their alternations, reliability of weaving, the presence of a protective layer);
• testing a fragment for fermentation, stretching (high-quality grid instantly restores its form and is not strongly stretched);
• testing for chemical resistance (the result is visible in a day after immersing the grid fragment in an alkaline solution, for example, the economic soap);
• the accompanying packaging document in which the information on the independent expertise of the quality of the goods should be.

How not to remember the folk wisdom about the miser? Plaster grid -it is not a way to shine with your material capabilities, and the calculated long-term investment on the perspective.

How to calculate the flow?

Conditions that it is necessary to take into account when calculating the material:

• wall area;
• possible surface irregularities;
• metage insulation;
• nutting the grid (online or bill).

Therefore, for the polymer mesh required 1.1 m² for square. meter Walls, and for fiberglass - 1.15 -1.4m². Specialists recommend providing stock 5% For unforeseen expenses.

Selection of plaster grid depends from the thickness of the finishing layer, irregularities of the walls.

Criteria are becoming:

• material;
• cell value;
• grid weight;
• method of fastening.

With significant drops of the thickness of the layer On the entire surface of the wall of the complex facade, it is recommended to refuse plaster and replace it with another type of finish.

How to mount a mesh under the stucco for outdoor work?

The technology of mounting the facade mesh is completely under the power of anything, consider the whole process of the detail.

Clean the wall from raid, traces of masonry work. Align the surface. If the chain grid is used - preparatory work And the primer is not needed.

Protect the surface for porous materials (aerated concrete blocks) - primer deep penetration.

Froze The treated surface and harvest cuts of the mesh material.

When working with a chain chain or welded, her box is made immediately on the wall Using a dowel or frame:

• on a wooden shepherd (for a wooden house);
• on metal pins (for brick or concrete walls).

How to glue the reinforcing mesh on the wall video

Polymer and fiberglass put the venge At the starting layer of plaster, while the reinforcing layer is pressed into the solution and is attached to the dowels around the edges.

The starting layer of plaster can be replaced by a special glue for mounting the mesh, after drying the finishing layer is applied. The glue can also be used to fasten the fiberglass to the insulation.

The adhesive layer should be sufficient to place the grid in its middle when indulging. Basis for adhesive fastening must be sucked And the work is carried out at the positive T◦ (not lower than + 5 ° C) On peeled spots and surface pollution.

With essential irregularities The walls need to install beacons (the thinnest layer - 1cm, the thick of it - not more than 5 cm). The solution is applied to the moistened wall, moving upwards.

Finish layer depending on the type of grid and the planned thickness is formed by a wide spatula from the middle to the edges, and, if necessary, in two navigation (with a complete drying of each layer) to flawless wall alignment.

Today we will talk about why and when the reinforcement of plaster needs. For the past decades, we have a conditional premises, the so-called "renovation". It allows you to carefully separate the surface, applying both European standards and modern materialsThis is limited only by materials, not paying attention to the repair standards.

European norms recommend, but do not oblige, the use of reinforcing grid in difficult cases. The reasons for these are incorrectly interpreted and switched to the discharge of legends. It is believed that reinforcing plaster is necessary to improve its clutch with the wall and preventing the formation of cracks. This is not quite so. To improve the adhesion of plaster, it is necessary to clean the wall well and apply the appropriate primers. The reinforcing grid allows to reduce the visibility of cracks, and not prevent their education. We will analyze this question more.

The reinforcing mesh is metallic and plastic. Popular as well as an analog plastic, fiberglass grid. Metal is used when plastering with strong irregularities and protrusions, sometimes exceeding 4-5 cm. When aligned, there accounts for a thickened layer of plaster, which, after complete drying, can decide and move away. This is especially important when plastering clay without using filler. So that this does not happen to reinforce the largest (more than 4 mm) metal grid. This is actually plaster grid. Why not plastic? Because plastic is less durable, energized with aggressive cement-sand plaster and is usually applied under the gypsum plaster a small thickness. That is, it is a painting mesh with a cell of 2-3 mm, which is reasonably used on finish finish Walls with putty or plaster with plaster mixtures with respect to smooth walls, with a thickness of plastering less than 20 mm.

In accordance with our SNiP, and with European building standards, the thickness of the plastering layer made by a gypsum mixture is on average. Such plaster, in fact, is applied in one layer. In reinforcement, the mesh is consistent with the freshly mounted layer of plastering to a depth of at least 2/3 of the entire layer without forming folds, with an overlap at least 100 mm (in places of adjoining one structural element to another - at least 200 mm).

Reinforcement of plaster on the surface of the walls in most cases is not fastened, but only in places of pairing various finishing surfaces and constructive elements. But when applied to the plaster layer on the surface or when working in a freshly botrated building, there is still no shrinkage, it is recommended to produce reinforcement throughout the area.

The research carried out by European manufacturers has established that in case of use gypsum plaster In new buildings susceptible to constructive deformations, it is possible to reduce the risk of cracks on the surface of the ochpaklyanny plaster under the condition of applying plaster in the form of a layer of 20 mm thick and its reinforcement with a plaster grid. My practical experience confirms these studies. So, when finishing apartments with an area of \u200b\u200b100 square meters. Meters on the seventh floor of a nine-story brick new building immediately after the delivery of the house there was a continuous reinforcement of a plastic painting mesh of walls and ceilings. Part of the walls and ceilings when working with plaster plaster, even two layers were reinforced. The plaster and plaster mixtures were carried out according to the cement-sand plaster left after the builders. Walls were preparing under painting. For three years after the completion of the repair, it was barely noticeable to the eye cracks in the spacion layer on the ceilings of all large rooms and on some walls. Such cracks will be easily embedded during the next cosmetic repair, for example, when repainted walls or shook wallpaper. It is easy to guess that the savings on the reinforcing grid in the finishing works in the cheese of a freshly directed building would lead to the formation of cracks throughout the thickness of the plastering layer and would force out to be reworked at least a spike layer around the room.

Plaster grid. Why need reinforcement plaster.

Alignment of walls with plaster mixtures requires preliminary preparation related to surface treatment and installation of beacons. Often, a plaster mesh is used for finishing - metal, plastic or fiberglass. In what cases is the reinforcement of plaster, and which grid is suitable for this?

According to European standards, the plaster grid is recommended for use as a reinforcing material. It is an opinion that it is necessary to reinforce the plaster for better clutch of the solution with the wall surface, or that the use of grids 100% guarantees the absence of cracks. In fact, the solution is well glued to the surface, if the surface is cleaned and covered with primer. And the use of plaster grids allows you to reduce the amount and size of cracks, their invisible.

In the market of Ukraine among building materials Plastic, fiberglass and metal plaster grid are available. The grid creates a frame of a layer of starting or finish plaster deployed on the wall. It must comply with certain requirements. It should be 150-170 g / μV.

The usual plastic (painting) grid is suitable only for plaster plasters that do not contain cement. The fact is that it is susceptible to corrupt with alkaline media. Therefore, it is used for finish plaster. In other cases, fiberglass meshes and grids impregnated with special compositions can be used for a small layer of plaster (up to 20 mm).

The metal mesh for reinforcing plaster is used in cases where the surface of the wall is uneven so much that the differences are 4 or more centimeters. When drying, the thickened layer of plaster behaves unpredictable and can decide and move away. In this case, even pre-priming walls does not save. If the cement is included in the plaster mix, then it is necessary to use steel grids, because compared to other materials, the metal is most resistant to corrosion of alkaline media.

The reinforcement of the metal is also recommended when plastering clay. For clay, it is better to use a grid with a large cell - 50x50 mm. In the external plastering of the walls of the first floor, a metal mesh is also used, because This part of the wall is often subjected to mechanical loads.

How to mount the plaster grid to the wall? For this, you need a dowel-nail with an outer diameter of 6 mm and a 4.5 mm self-tapping screw. We drill holes under fastening, cut off a piece of mesh in the height of the wall. Next, bottom is fixed by the grid of the dowel-nail, passing and pulling it along the way. For fixing, you can use washers, but it is expensive. Much more profitable galvanized perforated ribbon, which is convenient to cut. During the mounting of the mesh to the wall, you need to ensure that it does not lag behind the wall more than 1 cm and did not save. In the locations of the docking need to do Fasting.

The company "Metiz-Service" produces and sells steel plaster grids of all kinds: spark-exhaust (CPVS), welded, as well as a chain grid with a shallow and large cell. There is also a knitting wire and galvanized punched.

Reinforcement of plaster (external and interior decoration)

When coating reinforcement, the mesh is attached to any convenient way directly to the surface. wall coating. As the basis, there may be a wall of concrete blocks, brickwork, Wooden surface. The magnitudes of the cell and rigidity of the grid depends on the thickness of the plastering layer and the reinforced surface.

The plaster grid is stretched by the alignment of the walls by plaster, if there is no confidence in a durable clutch of plaster with base or layers exceed 20 mm.

Before tensioning under the ceiling after 20-z0 cm, holes are drilled. They are clogged with wooden plugs (very good for this furniture dials of a suitable diameter). Carnations are clogged into these traffic jams. Then cut a piece of grid in the height of the room. It is hung on the cloves of the bending inside the room, it will be easier to smooth it. Nails are bend, and then through the holes in the grid, the holes are drilled after 20-30 cm in height and length. They are clogged with traffic jams and nails pressed it to the wall. All edges are fixed. If the grid places depart from the wall, then they produce additional fastening. When drilling holes, it is necessary to take into account that there can be pipes and wires in the walls. Usually they are in 10-20 cm from the ceiling, or angle. If there are pipe conclusions on the wall, then the horizontal and vertical axes are better not to do holes.

The amount of mesh corresponds to easily based on the surface of the plastering surface and the width of the mesh. Corks and nails are required by about 25 pieces per square meter.

Does the reinforcement required plaster? - Library of apartment repairs.

Considering the fact that in most cases it is accepted in Russia repair work For a renovation and such a type of repair assumes its compliance with European standards, in the future we will also point to the construction rules adopted, in particular, in Germany in relation to works on the reinforcement of plaster.

Reinforcement of the inner plaster layer is usually carried out with plaster grid. Its purpose is to reduce the impact of the submissions to the finishing layers and minimize the risk of cracks associated with the mobility of such layers.

Plaster grid not applicable To increase the clutch strength of the plaster layer with the base. To do this, use special solutions like "Betokontakt" (see also materials for finishing works).

The use of such a grid is not directly provided for by the current Russian construction rules. In turn, European standards, although they do not prescribe the reinforcement of the plastering layer at mandatory, however, indicate that the application of the plaster grid is possible In the case when the need arises to reduce the risk of cracks in the plastering layer. At the same time, the reinforcement of the plaster layer, within the meaning of European construction standards, cannot serve as a means to prevent cases of cracking, due to the impact of constructive processes (for example, the deflection of overlaps, shrinkage, creep of the carrying structures or their deformation caused by the temperature drop) (see DIN V 18550 P . 4.3 Abs. 2, and p. 6.3).

The reinforcement of surface finishing layers, among other things, reduces visibility Crackers, which, due to various types of processes, manifest themselves in the underlying layers.

In accordance with the thickness of the plastering layer made by a gypsum mixture, it is 15 mm on average (which corresponds to European construction institutions). Such plaster is applied in one layer. In case of reinforcement of the plaster layer, the grid installed (blends) into a fresh and roaming solution of plastering to a height of at least 2/3 of the entire plaster layer (for example, at a height of at least 10 mm with a total thickness of the plastering layer 15 mm) without the formation of folds and even before the formation of the crust on the surface of the main layer is hidden The subsequent layer of plaster, having a height of no more than 1/3 of the total thickness of the layer (the technology of applying a "raw layer on raw base" or "wet vocoma") - in this way, all plaster works are made in one layer.

Plaster grid stacked with overlap Not less than 100 mm (in places of the adjoining of one structural element to another - at least 200 mm).

Reinforcement of plaster on the surface of the walls in most cases is not placed, but only in places of interfaces of various finishing surfaces and structural elements. When applying a plaster layer to the surface of the ceiling, it is recommended to reinforce the entire area of \u200b\u200bsuch a layer.

When cladding the surface of the walls, the reinforcement of the plastering layer is not produced. At the same time, the thickness of the plastering layer in accordance with European standards is 10 mm against 15 mm, provided for the subsequent belling of the surface or shelter with colorful layers.

Production plastering should be made, provided that mass The humidity of the subjectable base is no more than 8% (Russian SNiP) or residual humidity - no more than 3% (V DIN, Germany).

Our Austrian colleagues at one time conducted a detailed study and found that in the case of the use of plaster plaster in houses-new buildings, susceptible to constructive deformations (for example, in the form of a shrinkage), it is possible to reduce the risk of cracks on the surface of plaster, subject to the application of plastering in the form of a layer of thickness 20 mm and its reinforcement with a plaster grid.

Currently there are stacks of plaster and painted. The first has a cell size of 5 x 5 mm and is used to reinforce the plaster layer. The second has a smaller cell - 2 x 2 mm and is used when applying putty. In addition, the so-called "pautinka" - fiberglass, which is also applied to reduce its distribution in the Russian market. visibility cracks that may be formed in the subject layers.

Reinforcement of plaster metal mesh

When plastering walls and ceilings, it is necessary to deal with strong irregularities and protrusions. When aligning places, a thickened layer of plaster appears, which can over time to swell and move away. That this does not happen to use reinforcement. Such measures are recommended to take more than two centimeters with the thickness of plaster and on high surfaces. What materials can I use for this? A common-exhaust, welded and wicker metal grids are usually used, with a shallow cell. There are plastic plaster grids, cheaper, but less durable because Faster corrosive with aggressive plaster. When installing, such a grid saves and well, so you need experience. The metal grid has a more rigid and, at the same time, the elastic structure is easily mounted.

For the frame of plaster and preventing the appearance of microcracks, the foundation is perfectly suitable for the foundation, the grid is perfectly fits galvanized. Judge for yourself: it is elastic and fits well to the wall, repeating, its geometry, durable and does not have welded adhesions, protected from corrosion, has a low weight. Production of a sparkular grid is non-frequensed, so it has a low price. It is made by the spoken and simultaneous stretching of the galvanized iron sheet into diamond cells located in a checker order. Such a grid is durable, easily mounted and inexpensive.

For mounting the mesh to the surface, you will need a dowel-nail, perforator, knitting wire, lighthouses and scissors for metal. The surface must be cleaned from dirt and fat, process to. It is important that the solution is stuck to the wall, otherwise the plaster along with the grid will go back, and will be bone. Sut off the piece of the mesh in the height of the wall and the attitudes of the dowel-nail from the bottom up. In multilayer heavy systems, all loads account for the dowel and the grid and it must be considered when they are selected. Fasten the grid is comfortable with wide washers or two-per-nty-meter segments of the remaining lighthouse. You can buy a special galvanized mounting tape or punched and cut it into pieces of suitable length. Some simply clog nails not to the end and flex them, fixing the grid. There is still a method for fixing the plaster grid with knitting wire: you score a dowel not completely, we are taking the hats with a wire in the form of the letter Z and then we finish. With any method, we make fastening with a definite step. Somewhere 1 meter square accounts for 20-16 dowel-nails. The grid is well tensioning and pressing the wall as much as possible to the wall, the bulbs are more than 1 cm are not allowed. In places docking the grid put a mustle. The corners of the door and window openings should be additionally secured with slices of 300x500mm mesh. Then put the lighthouses.

After that, plastering the wall. The first layer is applied with a more liquid solution, sharp movements. It is necessary in order to through the small cells of the mesh, the solution was well glued to the wall. After that, leave it to dry. The second layer is picked up with a more thick solution and stretch upwards.

Use the reinforcing frame for plaster or not to solve you. The layer of plaster up to two centimeters do not need to be reinforced. But some argue that even at a layer of five centimeters, no cracks and detachment appeared. However, you should not experiment. Often such experiments come out sideways. Plaster seats, foundation settles. And the walls are cracked. And reinforcement gives the surface elasticity and mechanical strength. In compliance with all technological norms, the reinforced plaster wall is strongly protected.

During construction, an indispensable material is fittings. Reinforcement allows you to strengthen the construction and extend its lines of service. But for what you need to rein the walls, and what materials are needed for work? We'll figure out.

Very often in the process of construction or repair, you can face many wall defects, which are quite difficult to disguise or remove completely. You can align the wall using a bowl of plaster. But if there are many coarse irregularities on the wall or cracks, then the plaster itself will not be able to hide them. In such cases, you can apply the reinforcement of the walls by the grid.

The reinforced surface is more elastic and better perceives mechanical loads. The reinforcement of the walls of the grid is recommended if the thickness of the plaster 2 centimeters and more.

What is reinforcing for?

Reinforcement is used in such cases:

1. Irregularities of walls. In the process of alignment of the walls, you can face very large irregularities, to hide which will have to make a large layer of plaster. But the plaster itself is very heavy and if the layer is quite thick, he can appear and cut out.
2. Too smooth wall. In such cases, the grid helps more tightly clutch the solution with the wall.
3. Cracks. With the help of the reinforcement, the grid can significantly reduce the size of the larger cracks, and if the cracks are smaller, then and completely hide them. The grid also prevents the appearance of cracks and microcracks, if used in the construction process.

How to choose the right grid for the wall reinforcement?

There are many nuances that you should know when choosing a grid. The reinforcement grid is metallic, plastic or fiberglass.

Metal mesh is suitable for reinforcing walls with large irregularities (more than 4 centimeters). Metal works well in an alkaline medium and such grids can be used for plaster with a solution, which includes cement. The use of metal grids is also recommended if the plaster will be made of clay. Only in this case it is better to take a grid with a cell size of 50 × 50 millimeters. It is also well also reinforced by a metal wall mesh, which are often mechanically load (the walls of the garage, the first floor of the building).

The use of a plastic grid is possible only if the cement is not included in the plaster. Frequently used with a gypsum solution for the finishing wall plaster. Such a grid is cheaper than metallic or fiberglass, but not durable. When working with such a grid, experience is needed, as it quickly saves and deform.

If the layer of plaster will be thinner, then the possible use of mesh from fiberglass. Such a grid relatively well keeps the disclosure of cracks, but small sizes.

Mounting mesh

In order to attach the grid to the wall you will need:

• dowel-nails d \u003d 6mm and screws 4,5mm;
• perforator;
• wire knitting wire;
• metal cutting scissors:
• lighthouses.

The surface of the wall must be cleaned and handled the primer. The grid is cut into pieces so that the piece is on the entire height of the wall. Fastening We begin from below using a dowel-nail and go upstairs.

To fix the grid, you can heat the edge of the nail or use the assembly galvanized tape. Also, the grid is fixed with knitting wire. For this dowel, it is necessary to score not completely and on the Hats letter Z impose a wire. After attaching the wire to finish a dowel.

When calculating the required amount of dowels, you need to know that 1 m² will spend about 16-20 pieces.

In order for the grid to do not and not deformed it, it is necessary to stretch well and tightly press to the wall surface. If there are places where the grid is lagging behind the wall for 1 centimeter and more, then there the plaster can be detached from the surface. The joints of the joints need to make a bed. After fixing the grid, lighthouses are exposed.

Next, you can proceed to the first layer of plaster. It must be made with a liquid solution. It is necessary to apply a plaster solution with sharp movements so that it sticks well to the wall between the valve grid cells.

If the first layer is good, then you can apply the second. The finishing bowl of plaster is made of a more dense solution. Application must be taken up.

In the past few decades, we have such a definition of a renovation of an apartment. This means that there are some European standards recommended for execution in the process of fulfilling a renovation. One of these rules has become stuccoing walls with reinforcement, that is, plastering surfaces using the reinforcing grid.

Many believe that reinforcement of plaster is used to increase the adhesion (clutch) of surfaces and their protection against cracks. This is true, but only partly. For increasing and improving adhesion, special compositions are used, with which they make primer. Reinforcement of plaster, mainly make to fasten the plaster layer, which prevents it in cracking.

The reinforcing mesh can be metallic, plastic and fiberglass. Plaster reinforcing mesh made of metal has large cells with a dimmeter of more than 4 mm. The metal reinforcement grid is used when aligning walls with a large amplitude of curvature, when the differences in some cases can reach up to 4-5 cm. To plastering such curves, plaster is applied with a thick layer, which is often swollen after drying and departs from the surface. Reinforcement allows this to avoid.

Plastic mesh has less strength and can be subject to chemical effects of cement-sand plaster. The plastic reinforcing mesh has a cell of 2-3 mm, mainly applied under the gypsum plaster when applying a layer of a small thickness. Its use is advisable when applying a layer of less than 20 mm, with the finishing finish of more or less smooth walls.

Typically, a layer of plaster plaster does not have more than 15 mm and is applied with one layer. Reinforcement of plaster on the walls is often done with a solid coating, but partly and only in problem places. However, when performing plastered ceilings and walls in new buildings, which still give a shrinkage, reinforcement makes all over the surface. A painting plastic reinforcing mesh on the walls and a ceiling of new buildings protects the plaster of walls and ceilings from cracks.

According to the observations of European manufacturers of plaster plaster mixture, the use of the reinforcing layer on the walls of new apartments, prone deformation, the risk of cracks in the thickness of the entire plaster layer is significantly reduced. Consider a specific example. After passing a brick new building into operation, draft works were performed. The walls and the ceiling were shuffled with a plaster mixture on the construction cement-sand plaster. A painting mesh was used, in some places even in two layers. For three years, small cracks appeared in the upper spacion layer on the surface of the ceilings and on the walls in several places. Such cracks can be easily eliminated.

In this article, we describe the possible and most popular facade systems (facades). Technology and installation rules and insulation. Sequence of laying of films and thermal insulation. If you do not know how to insulate the design of facades and walls, then this article will help you pre-understand the question.

Facing system with veneer vinyl siding on wooden frame

System Description:

System frame racks are performed either from wood coniferous rocksor from steel thermophiles.

The space between the frame racks allows you to use light non-combustible thermal insulation plates (roclaight, technolate, parks, etc.), due to this, the facade insulation system not only becomes economical, but also has minimal thick walls. OSP-3 performs the function of hard ties in frame scheme Buildings and are the basis for the installation of vinyl siding. To increase the service life of the OSP-3 plates and the facade system as a whole, a superdiffusion membrane is located between siding and solid base. This material displays wet air from the facade and at the same time protects the OSP-3 plates from the street moisture that fell out of the lining (rain, dew, fog). From the inside, the system is protected from the convergence of a vapor barrier membrane, the adhesion of which is sampled by a connecting butyl rubber ribbon. The gap between vapor barrier and internal trim is designed for laying internal communications.

Plastering facade system with non-combustible basalt thermal insulation on a stone base

System Description:

The system has a high level of internal climate stability due to the location of the stone wall inside the warm contour. The various textures of the finish plasters and the possibility of a tinting gives the system large decorative capabilities. Due to high vapor permeability, the system is applicable on any bases. The non-combustible properties of the heat-insulating material makes it possible to apply this system on the facades of buildings of any destination, including on the facades of kindergartens, schools, hospitals, etc. Reinforcement of basic plastering with a special grid increases shock resistance, reduces the risk of cracking.

Plastering facade system with thermal insulation from polystyrene foam base

System Description:

The use of polystyrene slabs should significantly reduce the plaster system, but due to the flammability and weak vapor permeability of polystyrene in the design, it is worth paying close attention to the fire safety of the facade and ventilation of the interior. In the role of fire protection of the facade, non-combustible mineral wool slabs from basalt thermal insulation are used. The base of the system may be carriers, self-supporting and mounted walls of monolithic reinforced concrete of stone and arm-voices (density not lower than 600 kg / mk.) The basic plaster layer plays a protective role in relation to external mechanical and weather effects. The reinforcement of this layer grid increases the impact resistance, reduces the risk of cracking. The structure (drawing) of the finish coating is determined by the size and shape of the grain filler of the decorative plaster used by the tool, as well as application methods. Fireless service life of more than 25 years.

Layered layered masonry facade system with decorative brick facing

System Description:

Thanks to the brick facing, the system has a classic appearance, while the design is ventilated, which allows not overheating in the warm period of the year and not accumulate condensate in the insulation during the cold period of the year. With multi-storey construction to ensure the integrity of the design system relies on inter-storey overlap. To prevent the formation of a continuous bridge of cold into the overlap with monolithic works, thermal lands made from extrusion polystyrene foam TEKHNONIKOL XPS. In low-rise construction (up to 9m height), the system can be erected as a carrier element of the building. In this case, the overlap is based on the inner part of the wall, the outer laying is being erected continuously to the height of the building, and there is no need to the system of thermal lady. Heat insulation material This system must have good vapor permeability and rigidity. This requirements correspond to thermal insulation plates of technoblock. To prevent the outdoor verst collapse (masonry), it is connected to the inner flexible flexible bonds from basaltoplasty. This element additionally supports the insulation in the project position. System life of more than 50 years
