Home to coat

Sooner or later, the house starts to crumble. The first old facade: it is said the builders start "crying" - there are rough spots, and then crack. Gradually falls off facing, and if no urgent action is taken, the house will spread across the seams - from the front ... Why is destroyed? The first enemy at home - water. From school, we know that water soaks into all porous. Including in the sand and cement. Sooner or later, the house starts to crumble. The first old facade: it is said the builders start "crying" - there are rough spots, and then crack. Gradually falls off facing, and if no urgent action is taken, the house will spread across the seams - from the front ... Why is destroyed? The first enemy at home - water. From school, we know that water soaks into all porous. Including in the sand and cement. And in the winter cold water that has penetrated the wall cracks and joints freezes, increases in volume and year after year, expanding the cracks. In the spring the ice melts, the moisture accumulates on the walls, into a mold, and thrive on the wall of fungi and other microorganisms ... Not less than water, annoying facade winds. Complete the picture of the differences in our weather - then 30, then -25 ° C: and the facade of "throws" is literally something in the heat, then shivering: Another nuisance: the thermal load on the wall in the summer. True, the maximum load is when the temperature regularly rises to +35-40 ° C. The walls are heated, under the influence of so-called thermal shocks rock collapses and becomes thinner. In short, illness in front of the building has more than enough, and if so - they should be treated: Better yet - do to prevent them. How to save "face" at home? There are several ways to protect the facade. For example, you can use a traditional plaster. Help, but not for long - about a year. Water gradually make their "dirty business", adds the wind - and the plaster gradually osypletsya. In addition, the dirt, dust and exhaust fumes of cars literally eats into the plaster and clean up front - difficult and expensive: You can oblitsevat facade tiles - ceramic or marble, planting it, for example, the dry adhesive. But the tile, not less than plaster, is afraid of the wind and temperature fluctuations. Withstand a maximum of five to ten years, and then - crack, erasure color: In addition, experts say, if the house is over 20 meters, put the liner on the adhesive is dangerous - imagine if you fall off and fall on the head of passers-by? Can, in principle, to leave just a brick facade. Brick, of course, traditionally popular, but still "raw" brick facade looks over time, rather dull. In addition, the brick is also suffering from a temperature difference. What else? Batten! But the wooden wall paneling, will soon begin to darken, crack, and after 5-7 years of serious repairs can not be avoided. Not to mention the fact that the tree was afraid of fire. There are, however, is another very modern material that is not afraid of fire - cayding. It is also called vinyl clapboard. This strip length from 2 to 6 meters in width from 10 to 30 cm and a thickness of 1 to 10 mm. Siding is not foliated, no swells, no splits and peels off. Not afraid of moisture and mildew. Resistant to adverse weather conditions, non-flammable. Serves as a long, producers promise that it is easy to endure for decades (though, until we can speak only in theory). But not everyone is as well known, the soul (PVC), and the choice of colors is small. But most importantly - it is not clear whether under the house siding. Is there a way to save the facade? It turns out there is. And for several years has been successfully used in Europe. By the way, our builders are also evaluated this option facade. There is a real way to extend the life of the walls and lining of about 50 years! And maybe even more. Are you intrigued? We hasten to inform: a universal technology, which will be discussed, was in construction circles title. And in English this technology is called, that is. There is also another name - falshstena. But most fully the essence of the practical technologies can decode both Ventilated facades. The fact is that the wall of a house in a special way joins another wall, and between these walls is a space. That is really the facade is ventilated naturally. Once the reservation that ventilated facade is not suitable for every home. Ventilated facades are primarily used for the construction of urban, mostly office buildings. But you can use the design for a country house. And why not? But before I delve into the unknown, we shall understand the principle of a standard device in front of his, so to speak, as traditionally understood. Since the time of the add facade is nothing more than how to load the outer wall of the house, lined, plastered and often decorated with what some architectural additions - moldings, carvings, and so on. In the modern world under the facade are increasingly aware facade design. Standard exterior design looks like this: External walls - cement (or dry adhesive) - covering material, usually ceramic or natural stone (marble, granite). So, the construction of ventilated facades in many ways fundamentally different from the usual facade. Running along the sides So, what are the advantages of ventilated facade? Ventilated facade (falshstena) - structure, consisting of tiles for external cladding, the metal supporting structure that holds the tile layer of insulation, passing directly through the wall, and a ventilated area. Facing - ceremonial robe of the facade. Holds most of porcelain, ceramic tile, natural stone, aluminum. The choice facing determines, as a rule, the current fashion styles, colors and patterns. The metal support structure - like scaffolding. True, not mounted on the outside and inside the structure, behind the fascia. She holds the liner and provides an air layer between the wall and cladding. Insulation - mineral wool or polystyrene - gray-brown substance, dry and very soft to the touch, but dense. Fills 1 / 3 of the wall and cladding. Now there's a new special material - ventibat made by special technology of mineral wool. Ventibata thick layer of 8-10 cm is attached to the wall using special grips. In general, thermal insulation properties of insulation are determined by the system of international standards, depending on building type and climatic characteristics. Ventilated area or air space - takes 1 / 4 volume between the wall and cladding (the rest - a heater). Creates the effect, drawing: free air enters through vents and wall. How does ventfasad? Thus, we found that the protection system of ventilated facade of two-stage external influences. In the first stage outer facing skin protects the facade from rain and mechanical effects. It performs not only a decorative function: ventilation on the back side facing removes rainwater, snow and other precipitation, water flows down freely. That is no condensation of moisture, leading to the appearance of wet steam. The second stage - the output (extract), moisture, accumulated in an array of buildings and inside the building, again in a ventilated area. Heat loss in a layer of insulation is minimal, since it is made of waterproof material (not dampen). Here you have the effect of vapor barriers: no condensation - no steam, no steam - no moisture, no humidity - no fungus and related diseases of the facade, which we have already spoken. That is why the technology of ventilated facades ironically referred to as the most hygienic in Europe. Figuratively speaking, the house on the lining. As the lining, of course, stands heater. Moreover, this facade is not afraid of fire - it's made of noncombustible or nonflammable materials. I wonder what the builders say about the pros and cons of a ventilated facade? I turned to Sinani Demirer, a civil engineer with the experience. He works in the firm (Turkey) and took part in the construction of luxury housing in Russia and Europe, and such famous objects as the complex of buildings and facilities of radioactive waste in Moscow. Here are his point of view. Dignity ventfasada • First. Natural ventilation creates a comfortable climate inside the house without using any additional systems (air conditioners, for example). • Second. Dry insulation does not collect the condensate water and does not lose heat-saving properties. Means less heating costs. In addition, it reduces the thickness of the walls, to facilitate the foundation ... • Third. Any moisture is removed to a special drainage and does not settle on the walls. • Fourth. The system of ventilated facades created only from non-combustible or nonflammable materials, it is - extra protection against fire. • Fifth. Ventfasad perfectly absorb sound. Facade panels made of materials with improved sound absorption, plus a layer of insulation creates a double effect absorption. In addition, bearing wall that requires no special training to install on it ventilated facade designs and do not need to plaster the facade. Having dealt with the advantages, I asked about the shortcomings of Sinan ventilated structures. Disadvantages ventfasada • First. High price. Standard facade, of course, cheaper. On the other hand, does not require a ventilated facade and repair the annual cleaning, so as not accumulate dirt and does not lose any color, or strength, and virtually pays for itself in 5-6 years. • Second. All the advantages of a ventilated facade guaranteed only if the work is carried out highly skilled builders and assemblers. Other shortcomings as we try, and could not detect. Therefore, you understand the inner workings ventilated front, talk about facing. The visible and invisible savings benefit First of all, what keeps the lining? To ensure the air gap and at the same time securely lock the liner, the designers came up with a special mounting rail profile. Rack is made of aluminum or stainless steel. Steel profile easily keeps tiles from natural stone, and aluminum is commonly used for fixing a light tile of granite. System is facing, when the mounting rail tiles cover the top and bottom, called visible. System with hidden fasteners - invisible. Plus visible system - in its economy. Costing up to 2-2,5 times cheaper. Visible system is recommended for tile small and medium-sized. (Tiles, usually requires quite a lot, and if you use an invisible fastening system - would cost a lot.) Less visible system - in the event of a breakdown fragment of facing a number necessary to remove the entire series. Invisible mounting system is commonly used for formats from 45 x 90 cm and more. How to make hardware invisible? In the plate drilled four holes, there are inserted inside anchors (holders, similar to the bolts). Inside tile anchor disclosed, like the petals of a flower. And the petals, it is absolutely not visible from the outside, make the construction of sustainable and fixed. Pluses invisible system - its aesthetics. In addition, it added the guard of durable thin steel, which builders call. Makes use of the facade adamantly strong, so that any attempt to split off a piece of veneer home - it is absolutely impossible. And the amazing thing: apparently, this grid seems to be quite harmless. Something like mosquito nets, fluff with glue, but keeps the tiles are extremely tenacious. Why - the professional secret technologists. The only disadvantage of an invisible system - cost. But customers usually combine: Use at 1-2-storeys and above - the visible lining system. That much? Price Order ventilated facade is always calculated individually. With a significant amount of work is real substantial discount (its size is, of course, depends on the pricing policy of firm-seller). What is included in the contract that you sign with the company? First of all, take some time and visit the showroom of the company, which intend to conclude a deal. Here you will find information about the materials, the types of profiles and technical design decisions. The firm you calculate the working draft. It includes: plan, architectural drawings, engineering drawings, working papers. Designing a company normally carries a design department. Of course, we recommend you give preference to a firm that after assembling ventfasada provide warranty and service. Let's count up all the same: what to minimum and maximum cost? For example, we need a facade with a visible coating system and, of course. Here is a sample calculation: • 1. Calculation of the project - 4.5 cu per square. • 2 pm. The cost of tile (ceramic) and hardware (aluminum) - 100-110 cu per square. • 3 pm. Insulation - 4,5-7 Euro per square. • 4 pm. Delivery and installation - 60-70 cu per square. m. Total - about 170-190 USD per square. m. But how much will cost veneer of marble (for instance, take a large slab of Italy), plus an invisible mounting system: • 1. Marble (45 x 90) - 130-150 cu per square. • 2 pm. Steel profile with an invisible system - 60-70 cu • 3. Insulation - the same 4,5-7 USD • 4. Installation - 60% of the cost of the material. Total - not cheaper at 250-300. is, for the quarter. m. Recall that the economical combined visible and invisible system, using different modules. Another important issue - timing. To create a working project usually takes 3 to 5 weeks. Choice, delivery of materials and proper installation lasts at most 3 months. When months of trouble left behind, you're admiring the gold-matte exterior, illuminated by the setting sun, you feel that your efforts are not wasted ... Your house is painted in porcelain stoneware. And inside - dry, warm (winter) and cool (in the heat) ... What else a man need to be happy? Source: Building portal Gvozdik.ru
