Choose a system of warming of the walls is not easy, because of heat engineering efficiency, they differ little. Crucial to the reliability and functional efficiency, versatility and ease of practical application. It is necessary to take into account the parameters of a particular building or project: the possibility of additional load on the foundation that is acceptable (including depreciation), the load on the wall, the system conforms to the landscape, and of course its cost. Properly assess all these factors can only be a professional. Applied Systems outer insulation of walls of buildings can be divided into: thermal insulation system with plastering facades; thermal insulation system with a protective-decorative screen, thermal insulation system with facing brick or other fragmented materials, thermal insulation system of low-rise wooden houses. Thermal insulation system with plastering facades include adhesive or mechanical fastening of insulation with anchors, dowels and cages to the existing wall and then covering his plaster layers. Besides the general requirements for a reliable fastening system to the existing wall, in the thermal insulation system required under the terms of the annual balance vlagonakopleniya is the requirement for water vapor permeability nakryvochnyh plaster layers. Thermal insulation system with protective and decorative screen because, as a rule, its lack of water vapor permeability perform air-ventilated gap between the insulation and shield, the so-called ventilated facade. Screens used for the manufacture of metal (steel or aluminum), asbestos, steklofibro, concrete, plastics and other materials. Thermal insulation system with facing brick or other fragmented materials have sufficient water vapor permeability and does not require that the device ventilated air gap. Due to various mechanical and temperature and moisture deformations main wall and facing brick layer height is limited to the last 2-3 floors. Wall insulation with low-rise wooden houses can be performed using any of the above systems. Hinged front If you want to live in a respectable house and spend as little time and money to care for the facade and its repair, then why not choose the hinged system. Hinged facade will provide a great microclimate in the house at considerable savings. It can not be applied only to homes with non-planar walls and elements of architectural decoration (columns, cornices, etc.), as well as the restoration work when you want to preserve the historical appearance of the building. Thermal insulation system with a hinged facade - ventilated facade - is a multi-layered wall, the inner layer is of relatively heavy and durable materials (concrete, brick) is a carrier. On the outer side of the insulation layer is fixed, it is usually made of water resistant materials. Then, with the air layer (ventilation channel) to the supporting wall mounted decorative and protective screen. The latter protects the walls from the weather in the summer reflects the sun's rays. In addition, through the vent upward air flow carries a significant portion of the heat transmitted through the screen. That is one of the main advantages of such a facade system: it allows to save not only on heating but air conditioning. In winter, go through the vent water vapor leaking from the premises, preventing the insulation from moisture. Air gap reduces the heat loss by about 8%, since its temperature by about three degrees higher than outside. Curtain walls provide sufficient strength of the containment. In their use reduces the humidity and temperature fluctuations in the bearing wall (which lowers the risk of fractures), there is no resonance and vibration is attenuated. Application suspended facades effectively in the construction of cottages and without insulation, since it allows to protect the outer wall and save on heating in winter and air conditioning in summer (due to heat dissipation through the vent). For example, two-storey cottage, first floor is brick, the second - from a bar. You can decorate the first floor tiles under the stone, and the second - siding (both floors, naturally, from the ventilation gap}. And the view from the cottage will be completely different, but its price in the sale will be much higher. When installing completely eliminated the "wet process" - plastering, installation of cladding on the cement mortar, etc., which allows you to work at any time of year. Ventilated facades ventilated facades hanging known in Russia about 15 years. Then, as for many years, ventilated facades are used in some countries (eg in Germany, Finland) for insulation and finish of social, administrative and industrial buildings, as well as retrofitting of mass building. Nevertheless, hardly appeared in Russia, ventilated curtain walls immediately gained popularity. explains the interest in them is quite simple. Ventilated outboard facades allow a short period of time and in virtually any weather conditions trim the facades of buildings, providing thermal protection facilities, high quality and durability of the facade. For warming of outdoor structures between the wall and facing facade system involves the installation of insulation layer - in this case the gap left between cladding and insulation. There are, however, vented design with a slightly different arrangement of heater and air gap. Advantages of ventilated facades: opportunities to use modern materials, high heat and sound insulation, ventilation of the inner layers - removal of atmospheric moisture and moisture is formed by diffusion of water vapor from the inside; protection of walls and insulation from the weather; leveling thermal deformation, the ability of the finish at any time of year - are excluded "wet" processes, no special requirements to the surface of the bearing wall - its pre-alignment, and moreover, the system aligns the defects and surface irregularities what to do with the application of plaster is often difficult and expensive, maintenance-free long-term (25-50 years depending on the material used). In short, the insulation of the facade with panels - a sandwich, make it possible, on the one hand, decorate the house with modern durable materials, and on the other - to protect the building envelope of bad weather. Wet type What is the system of external insulation of the facade of "wet" type "concept" system "says the heterogeneity and complex interactions of its constituent elements. There are three main layers of the system: thermal insulation - slabs of insulating material with low thermal conductivity (such as mineral wool or polystyrene), reinforced - a layer of special adhesive composition of mineral-reinforced alkali-resistant mesh, protective and decorative - a primer and a decorative plaster (mineral or polymer) is possible with special paint "breathable" paint, can also be used facing materials (eg, clinker tiles). Each layer performs its function in the system. Heat-insulating material provides insulation enclosing structure, its thickness is determined by the thermo-technical calculations, and the type of material - fire protection requirements. Reinforced layer is necessary to ensure adhesion of protective and decorative layer to the surface of the insulation plate. protective and decorative layer performs two functions: it protects the insulating material from the unfavorable external influences (UV radiation, precipitation, etc.) and also gives the facade an aesthetic appearance. In the "wet "warming of the facade also apply additional elements that provide: increased corners of the building, window and door slopes, the contiguity of the roof, windows and doors; adherence to the basement, protect structural joints of the building, and so on. The choice of material depends on the additional elements their chemical compatibility with other materials systems. Application of the outer insulation of the facade of "wet" type allows to significantly improve heat and sound insulation enclosing structure. For reliable and long life of the system is necessary that it was designed taking into account the diffusion of water vapor and its condensation and moisture transfer. The system should have the necessary chemical resistance. An important factor with no problem functioning is robust and reliable foundation enclosing structure, which is mounted system. Multilayer insulation systems "wet" type with the effective heat insulation of mineral wool or polystyrene foam can easily reach the required values ??of the reduced thermal resistance to heat transfer R0TR walling. At the same time enclosing structure itself may have a thickness that is calculated only from the condition of sufficient bearing capacity. We also note that light frame construction, are known to have a low coefficient of heat absorption material of the bearing wall. However, this is sufficiently compensated by the high thermal resistance insulation material. Apart from the main purpose - insulation enclosing structure, the system of "wet" type substantially increases the insulating properties of the outer wall. The system of "wet" type is a classic example of a two-layer acoustic design, where the two shell structures excited by the sound varies independently from one another and are linked only by air or a layer of insulating material negligible stiffness. In Russia the system of "wet" type is an oscillating system, obey the principle of mass - spring - mass. As the mass of the act of bearing walls and external plaster layer, spring - thermal insulation material from mineral fiber or foam. Soundproofing can be significantly reduced, theoretically, even to zero, when both masses start to oscillate with the same frequency, ie, resonance occurs. Thus, the analysis of this model, the oscillating system is to assess the frequency band to the resonance in a resonance zone, after the resonance and standing waves in the area. In terms of sound insulation that optimal multi-layered fencing design, in which the resonant frequency issued for the area of ??so-called "building-acoustic frequency. fire protection as a heater can be used as non-combustible materials (rock wool) and flammable (with some restrictions) - polystyrene foam, polyurethane foam, etc. approval of regulatory documents containing the rules of safe use in the construction of systems of external warming with combustible insulating materials, to date not been developed. Therefore, their use is allowed only after the passage of fire tests insulation systems. In multilayer structures are commonly used materials that differ substantially in vapor permeability and water absorption. For such designs (along with the calculations of the reduced thermal resistance and heat resistance) is extremely important is the question of storage, which must be seen in winter and summer conditions. It is well known that There are always temperature difference inside and outside the building, causing the partial pressure difference and as a consequence, the diffusion of water vapor through the building envelope. Also, if in any area of ??the enclosing structure temperature drops to the dew point (saturation temperature of steam), then a loss condensate. The process of the moisture and its accumulation in the designs can be attributed to one of the most harmful factors, leading to the destruction of products, reduce heat protection, the appearance of mold, fungi, etc. multi-layer structures is compounded by the fact that the layer having minimum vapor permeability, can act as a vapor barrier. Thus, the quantitative calculation of moisture transfer is one of the most important in the design of a multilayer cladding design. Computer method of calculating the moisture transfer through a system of "wet" type, which is actively used in many countries around the world, is as follows. The first phase water transfer is calculated in 1 hour, and then - for the entire period of accumulation of moisture in the design. During the period of accumulation can take a duration of a few winter months with the average calculated temperature and average relative humidity. The second stage is calculated moisture transfer for 1 hour, and then - for the entire period of evaporation. During the period of evaporation can take a duration of a few summer months with the average calculated temperature and average relative humidity is. Duration of periods of accumulation and impact of moisture is set for each climate zone. A properly designed system is "wet" type must satisfy two criteria : excessive amount of moisture should not lead to waterlogging of the enclosing structure, the amount of moisture that evaporates from the enclosing structure during the summer period, exceed the amount of moisture accumulated in the winter. In the "wet" type as a variety of bearing and fasteners can be used in products metal, such as cores for plastic dowels, etc. In addition, the system may be in or pass through it constructive metallic elements such as railings of balconies, the output of communications, etc. All these elements must be protected by special corrosion compositions (primer or paint). All non-metallic elements of the system (eg, polymeric sleeve dowels, reinforcing mesh) must possess the necessary resistance to alkali. Durability is a time during which the system maintains its performance characteristics. Durability is usually confirmed by tests in a climate chamber where the sample system cycle the low and high temperatures at different relative humidities. It periodically sample is irradiated with ultraviolet and infrared lamps. The number of cycles that a sample stand without visible damage, tentatively estimated longevity. Obviously, the final of the durability of a thermal insulation system can be judged only after a long practical use. In November 1999, eight leading European countries (Denmark, France, Finland, Germany, Netherlands, Italy, Portugal, United Kingdom) have adopted the document "Basic provisions of the European Technical Approval of external thermal insulation of complex systems with plaster" , which sets the lifetime of systems with "wet" type. In accordance with this document longevity certified system is 25 years old when she delivered a dealer properly designed and installed properly exploited. It must be emphasized that in designing a system to ensure compatibility of adjacent layers thermal expansion, water absorption, frost resistance and water vapor permeability (with increasing outward), as well as good adhesion layers with each other (increasing as it moves from outside to inside). Use of materials with disparate properties leads to negative results and additional costs for the production of customer repairs. Usually the system comprises the components (insulation, mesh, plasters, plugs for mechanical fasteners, etc.), produced by various manufacturers. However, commitment to quality work all the disparate elements together takes one company - the developer of the system. For this objective tests are conducted as separate elements in the system and the system as a whole. System has been tested, have a technical certificate State Construction Committee of Russia on the suitability for use in Russia. You must understand that a seemingly insignificant change in the system of some elements others can lead to a significant reduction in maintenance-free service life of the facade. Completion of Outdoor insulation plastering the facade with additional elements (the angle guide, ground and curtain profiles, elements of the adjacency, etc.) can vary, but the system chosen for the additional elements must have confirmed the parameters of accredited laboratories, not referred to below in the technical certificate. The device external thermal insulation is essentially the final stage of construction. bearing wall should have time to dry, and it can not prevent its subsequent soaking wet. By the beginning of works on insulation should be installed roofing, built-in Window and door frames, ready to balconies, canopies are installed and flow, all the necessary joints and junctions. should be completed working on installation of drainpipes. It is advisable to have completed the internal plastering ("wet") processes. In the course of action is needed to preservation insulated walls from the effects of rainfall, as well as from direct sunlight. Scaffolding, if necessary, their use should recede from the bearing wall in the distance, taking into account its own thickness of insulation and working space for its installation. facade insulation systems "wet-type "fall into two design types: a system with a rigid fixing insulation on the wall (of 'sealed' type on the European terminology), and a system with flexible (mobile) fasteners insulation. facade Care System As part of the design-budget documentation should specify (see the instructions ) to care for a specific system to thermal insulation system keeps the stability of their work and aesthetic properties. Particular attention should be paid as protective and decorative coating and protecting the upper part of the system (parapets, cornices, sills in the window openings). Identified violations of the appearance of a ventilated insulated facade should be classified in two ways: the natural aging of the protective and decorative coating that does not affect the stability of the system as a whole; damage to individual elements of the system, which can lead to failure of individual sections or entire system of insulation. With respect to the ventilated facade insulation should be provided such measures to park cars near the building was not possible mechanical damage to the wall. Do not! Strengthen, in the process of building and operating the building, any part or device directly to the layering structure (for them should be installed in an independent supporting frame). Do not let water from the roof of the building on the cladding systems, which must contain in working on the roof gutters and drains. Caring for facade cladding is in its regular cleaning, periodic inspection and primer-staining appeared scratches and damage. Rinsing with water is one of the most effective ways clean lining. To wash water delivery hoses under pressure of 2-3 atm. washing is recommended to combine with the manual cleaning of the surface with brushes. When serious violations of, or damage in the ventilated facade insulation is necessary to contact the installation company and follow their recommendations to address identified defects. Suspended ventilated facades hardly in need of care. Very often, the rains help to effectively get rid of pollution and maintain the purity of the cover. However, the presence of contamination largely depends on local atmospheric conditions at the site where the building. In the industrial, coastal areas and areas that have been construction work may need more frequent cleaning works not only because of the need to maintain the appearance, but also to remove contaminants that can cause damage to the coating. usually work on cleaning and washing are carried out in the direction from top to bottom building, and for single-story buildings or lower is recommended to clean the bottom up and rinse - from top to bottom.
