What is more environmentally friendly, durable, economical: brick, foam blocks, «sandwich»? The main requirements for modern housing is durable and environmentally friendly. Just Such parameters provide modern construction technologies, which are built at home. Townhouses by definition - an inexpensive type of real estate, so the use of any building innovations would have to reduce their costs and, consequently, price. But while this is not always the case.

Brick, foam blocks or a sandwich?
According to Alexander Libov, CEO of real estate agency "White Winds", the construction of townhouses in the suburbs used approximately the same list of technologies used in the construction of individual country houses - is a brick, a sandwich panel (Canadian technology), foam blocks of expanded clay Concrete and gas silicate. Yuri Sidorov, head of capital construction projects "Veles Capital Development, told the magazine Metrinfo.Ru, that here also include permanent form of different manufacture.

Some specificity consists in the fact that the townhouses is primarily associated with housing is not the highest category, and therefore expensive materials are used infrequently, said Alexander Libov ("White Winds"). In the villages of economy-class and lower business segment being applied foam blocks and sandwich panels, says Denis Izmailov, head of the suburban real estate CENTURY 21 Street Realty.

In particular, the townhouses in the villages of "Little Scotland" (Leningrad highway, 14 km. From Moscow) and Pokrovsky (Novorizhskoe highway, 23 kms.) Constructed from the autoclave gas silicate blocks, "says Natalia Ivanova, Director of Sales of the village of" Little Scotland " . The geography of this technology encompasses all climatic zones and continents, and is perfectly suited to the rapidly changeable climate of Moscow region. For example, the townhouses of the foam blocks are located in a cottage village "Dubrovka (Kalujskaya., 5 km.)" Bylov (Kalujskaya., 22 kms.) "Embankment" (Dmitrov, 2 kms.).

Elena Sergeeva, head of the suburban real estate company "Russian House Real Estate, said that in the village Opushkino on Novorizhskoye highway (38 km. From Moscow), the company is building townhouses of two types - made of bricks, as well as through framing technology.

According to Denis Izmailov (CENTURY 21 Street Realty), a brick - the most common material for construction of town houses in the settlements of class "business plus" and "premium". The main clutch is made of brick, finished with a ceramic facing brick house. This technology is considered the most environmentally friendly, thermal efficiency, trouble-free in the subsequent operation, but the truth, and the most expensive, so in a segment of "economy" is not widely applied. The most famous towns, where town houses are built of bricks: "Ilyinsky quarter (Novorizhskoe highway, 7 km.)," The Maple Grove "at the New Riga (10 km. From Moscow).

The expert also noted that all the settlements at a distance of 30 km from Moscow in the "gold box" from Minsk to Volokolamsk highway, and earlier settlements on the Rublyovo-Uspensky highway, built of brick with a monolithic concrete frame. Recently, however, in the "high" segment of real estate developers have started using uncharacteristic construction technology - non-removable panel formwork. Almost all the houses in the settlement of business-class "Larks-1" on Mozhaisk highway (20 km. From the Moscow Ring Road) built on this technology - says Denis Izmailov (CENTURY 21 Street Realty).

Advantages and Disadvantages

Any technology in housing construction has its advantages. As explained by Alexander Libov ("White Winds"), the main purpose of introducing new technologies for our market, usually one - cheaper and possible acceleration of the construction. Many modern materials fit perfectly into this concept, allowing you to build homes faster than traditional materials - brick and a lower cost.

Natalia Ivanova ("Little Scotland") told me that gazoselikatnym blocks are not afraid of mold and fungus. The walls of the materials are resistant to any weather conditions, strong wind, rain, snow. Silicate blocks have excellent thermal insulation properties. Since silicate brick six times warmer than ordinary brick. Therefore, even in the harshest winter in a house built of such material will be warm and cozy. Gas silicate blocks characterized by a high degree of thermal insulation, as well as through the accumulation of heat throughout the house remains a constant comfortable temperature. Use of additional insulation and finish of the ceramic tiles or bricks, creating the effect of a thermos, which saves on heating in winter and summer did not experience discomfort from the heat.

An important advantage in favor of the material lies in the fact that gazoselikatnye blocks have a useful property to regulate humidity in the room. They can absorb excess moisture, or conversely, overly wet, dry air in the room. In addition, gazoselikatnye blocks perfectly absorb sound and do not burn - add Natalia Ivanova ("Little Scotland").

According to Alexander Dubovenko, Director of Development for Good Wood (GOOD WOOD), for the construction of townhouses excellent material - foam blocks. Foam is a supporting structure, and also has thermal insulation properties. A major disadvantage of this material is the low life - only 25-35 years.

Technology is non-removable panel formwork came to us from Germany and the USA. Houses are built as follows: from polystyrene foam or produce hollow frames of the walls (they are kept as blocks of Lego), then the voids are filled with reinforced concrete, and get ready padded on both sides of the wall thickness of about 20 cm This home is durable, holds heat well and absorbs sound. However, the big problem is the design air permeability and recycling. Denis Izmailov (CENTURY 21 Street Realty) drew attention to the fact that doctors have not agreed with respect to health safety long-term presence in these homes.

The main advantages of Canadian technology - high speed of construction and low cost. Overall design house has a relatively small weight, which does not create a large load on the foundation, so the cost of laying down. Experts assert that the frame construction gives the opportunity to put even the most complex designs with minimal financial costs. In addition, the energy consumption for heating of the frame house at least 30% lower.

Another plus frame technology lies in the fact that members of her designs can be replaced. Elena Sergeeva from the company "Russian House of Real Estate said that the construction of townhouses in the village Opushkino" for the erection of light steel frame used in thin-walled structures, whereas in the classic Canadian technology of wooden frame and less durable. "The steel construction of our townhouses manufacturer guarantees 100 years", - says the expert.

Claim to frame technology


According to experts, most questions from buyers is just skeleton (Canadian) technology. And if there is a choice, they prefer to buy the house of another material. According to Denis Izmailov (CENTURY 21 Street Realty), caution buyers not meaningless. After all, that no matter how far stepped technical progress in the production of wooden panels, initially "Canadian House" were not designed for long life. In particular, the U.S. idea of pre-fabricated homes from as cheap readily available materials has attracted real estate developers during the 50-ies, when the postwar period, began to rapidly built up "potato field" and has inspired many an opportunity to leave the metropolis and only $ 5 thousand to buy your own townhouse with a plot of land.

Currently used in the construction of new, more sophisticated and energy-efficient materials that can help improve frame technology. Therefore, in North America, one is most used in the construction of low-rise housing.

In Russia, the Canadian House settled down a little. True, the difficulties of using frame technology lie not so much in itself, as well as performance. According to Alexander Libov ("White Winds"), problems may arise due to the fact that the quality of construction in Russia do not always correspond to the standards of Canada. The country has strict environmental controls over the quality of raw materials and products, as well as the process of housing construction. As for us in the field of low-rise building there are no strict rules, and each relies on its own view on the subject. Therefore, at construction sites and in the snow and rain can be seen working, paving the sopping insulation, which negates the main advantage of the sandwich technology - thermal efficiency, says Denis Izmailov (CENTURY 21 Street Realty). As a consequence, the subsequent operation of the owners of the house to face a lot of problems. Including the possible defects of wiring, which is laid inside the panel, which threatens to fire or other trouble. And the only way out here - strict observance of technology.

However, the frame technology is improving and we have. So, Elena Sergeeva ("Russian House Property") said that the construction of townhouses in the Opushkino for insulation used durable basalt or mineral plates, which require no maintenance. Although confirmed that there are developers who save on a heater and used mineral wool. A cheap material quickly loses its properties and will have to be replaced every 5-10 years - she warns.

In general durability of frame houses is estimated at 30-50 years, but since the properties of their fillers studied, how accurate calculations, can be seen only over time, "says Yury Sidorov (Veles Capital Development)."

What determines the price


In Moscow a pricing policy for country market rather related to the location of the house, far from the capital, the quality of the land and only then with the technology on which the house is built.

As practice shows, the prices of townhouses being built on different technologies, differ not so much. For example, as described in the company "Russian House estate, in the village Opushkino" cost of frame and brick townhouses are about the same - from 3,8 million rubles. The price includes finishing turnkey communications with the institutions.

In "Little Scotland" villa area of 164 sq ft of gazoselikonovyh blocks with a plot of 1.8 hundred parts worth 6.7 million rubles. In the village of "Embankment" on the highway Lihachevsky townhouses on the Canadian technology are sold at a price of 8.5 million rubles. per section. In the village of New Veshki (Altufevskoe highway, 1.5 km. From Moscow) of the Canadian section of duplexes sandwich panels total area of 240 sq ft starts at $ 850 thousand, and the price for townhouses in the section "Elias quarter" start at $ 650 Thousands of Alexander Libov ("White Winds") recognizes that the use of modern technology allows developers to reduce the cost of constructed housing. But, in his opinion, the prices of such objects is low enough, and this is one of the reasons why houses built on new technologies, not as well marketed.

Summary log Metrinfo.ru

A good house can turn virtually any technology. Importantly - to observe it, that we do not always. Somewhere something is not report back, somewhere something forget. And who is in Moscow working on construction sites? That's right, immigrants with questionable qualifications for the penny salary. How then to check the quality of construction? We have dedicated this topic a few articles ("We buy a country house in the summer. How can I see flaws of construction, which concealed the snow," "Features Winter Smotrin and suburban real estate purchases: see what is hidden"), you can deduct the tips. But one thing is clear - if you decide to purchase, will have to dive into this topic and control the process.
