The appearance of ventilated facades was a breakthrough in building practice. Architects, builders, and customers - all appreciated the ventilated facade of dignity. Installation of ventilated facades for optimum heat and sound insulation of buildings, improve the microclimate inside the premises, to create an aesthetic appearance, to protect from the effects of structural engineering. Ventilated front is a structure consisting of materials cladding (boards or sheet material) and design-facing, which is attached to the wall so that between the facing wall and formed a ventilated air space. For additional insulation between the wall cladding and lining may be placed insulating layer - in this case, the air gap is formed between the casing and insulation. -Facing design can be mounted on a carrier, and the self-supporting wall made of different materials (concrete, brick, etc.). To ensure fire safety in the system of suspended facades include materials and articles belonging to the category of slow-or non-combustible, preventing the spread of fire. However, there are a number of problems of compliance of ventilated facades relevant norms: the benefits system in which the lining of the building is separate from the supporting structure and would be able to meet all the loads and at the same time provide a solid defense. Becoming an independent structure, the ventilated facade has allowed implement a variety of aesthetic architectural solutions. The requirements for thermal protection of buildings ventilated facades pushed to the fore. The system allows the use of ventilated facades insulation thicknesses, which leads to savings in space heating the building, reducing energy consumption by 30%. Insulation used for ventilated facades must have the following properties: • be durable, resistant to aging material; • be biologically persistent; • have permission from the fire inspection on the use of ventilated facades; • have a stable shape, fitted with a continuous layer, Excluding the occurrence of "cold bridges"; • have high thermal insulation properties; • allow water vapor and moisture to enter the air space, Preventing the formation and accumulation in the construction of the condensate; • be resistant to the wind flow; • be non-aggressive to the metal podoblitsovachnoy design; • meet the requirements of GOST 9573-96 "plates of mineral wool insulation in the synthetic binder. Specifications "in terms of stiffness of the material. In addition to the insulating characteristics of ventilated facades can absorb sound waves. The greater the thickness of the insulation, the higher the sound insulation performance of the building. Hospitals, residential and administrative buildings, located near the busiest transport routes - ventilated facades provide a high sound insulation. The big advantage is the ability of ventilated facades of buildings with the help of sanctions to be installed on the damaged wall. Timely ventilated facade device eliminates the need for a range of activities: removal of old flooring load-bearing wall, drying damp walls. Ventilated facade is a contemporary design solution that can be applied to both new and renovated buildings. Version of the material used for the cladding of the facade - is extremely rich, and this is natural stone, and its counterpart, and metallosayding and metal facade cassettes, and metal panels. During the construction of new facilities using ventilated facades can be determined by the following factors:: • simplicity of care; • bezremontny long service life; • soundproofing of the building is improved; • constructive division lining, insulation layer to avoid damageDue to moisture; • The various elements of prefabrication can implement various design options and layouts. The growth of the construction materials market stimulates the development of new systems of ventilated facades. In such circumstances, attention should be paid to the quality of the material. In a market economy, the quality of any product depends on its price. Make a decision on the application of certain materials that are part of ventilated facades and approve installation of the technology may only be a specialist. Documents that need to guide the assembly, installation and quality control, ventilated facades, is - technical specifications, ghosts, quality passport, certificate of compliance. Manufacturer of ventilated facades is responsible for ensuring that their material according to the documents, as well as the quality of the material and maintaining the technology systems installation of ventilated facades. In case of emergency as the responsibility of the organization assembled and manufacturer of material for ventilated facades. The manufacturer is responsible for the design of ventilated facades, especially for ensuring the carrying capacity of the system. Systems of ventilated facades are constructed on the same principle, they may differ mounting technology. Particularly careful handling, during installation, requiring imports of ventilated facades. Statements about adoptatsii manufacturers of such systems to the Russian construction conditions are likely to be only an advertising slogan. The main factors determining the concept of "Russian Case" are: a large curvature of the walls, high requirements for fire safety, significant changes in temperature, lack of qualified installers. Therefore, the expression "support domestic producers" in this case is not an empty statement hilarious. License for facade work in the organization - says there that it is allowed to engage in that activity, but does not guarantee the quality of its work. Hence we have a problem on the front, despite the use of quality materials. Analysis of accidents shows that it is non-mounting technology is often their main reason. Much as ventilated facades depends on the leaders of assembly companies. Some of them, referring to the load, have no desire at least occasionally attend personally mounted objects. An important factor affecting the quality of ventilated facades, is the "turnover" of personnel in assembly organizations. Problems in design and construction of ventilated facades 1. Ventilated facades - Facades of piece goods. Accordingly become critical distance between the windows (both vertically and horizontally). If they are different - it's much more noticeable than in the manufacture of plastering work on the facades, as visible "serialization" lining. 2. Wall material. There is a big mistake when a bookmark for wall openings silnoporistye use materials with low bearing capacity of anchors by the action of longitudinal and lateral forces with respect to the axis of the anchor. The use of such materials is not justified, primarily, for economic reasons. The fact that the thermal efficiency of such materials is less than the thermal efficiency is applied as insulation of mineral wool. 3. Some of ventilated facades have a very nasty flaw. At certain wind whistling or humming it. This is especially true in the field of wind swirling flows. The use of small (4 mm) gap between the plates lining significantly reduces these unpleasant effects. Instead of conclusion In search of beautiful and durable facade following guidelines: • manufacturer of material for ventilated facades must be domestic; • exist in the market of construction materials for at least six months; • The quality of the material for ventilated facades must comply with existing requirements; • Mounting the organization must have a license for the appropriate execution of workt; • experience in installation of ventilated facades in the contractor organization; • an opportunity to look in the ventilated facade (the building, lined with this material and construction firm selected by you); • recommendations from other consumers of ventilated facades. With proper organization, a permanent quality control, skilled installation, you can get a quality, durable facade mounted in accordance with the requirements. Distinctive features of the use of ventilated facades of JSC "CHETZ": 1. The maximum thickness of insulation to 200 mm, and due to the form of brackets, which leads to the possibility of use in any climate. 2. High load carrying capacity of the system (the system is applicable without restriction height of the building). 3. Use as a liner ANY board materials (ceramic, mineral, fibrosteklobeton, etc.). 4. Russian production. As a consequence - the possibility of a phased assembly facility, as well as the rapid production and delivery of non-standard items. 5. Ability to produce work on their own, of their own material and from material produced by other manufacturers of similar materials. 6. The presence of TU, ​​the conformity of individual elements of a ventilated facade, and the whole system. The system is currently undergoing certification for the Technical Certificate Construction Committee. http://fast-ch.ru/
