Japanese house of foam plastic - housing of the XXI century. Dome Houses in Japanese Technology

The Japanese are distinguished by the ability to find unique solutions and create innovative technologies. One of the construction companies of the Land of the Rising Sun proposed a fundamentally new concept for the erection of a single-storey residential building.

What is a domed house?

The building has a domed shape. But the most unusual is the material from which the walls and other segments are made. This is styrofoam. Its use may seem too revolutionary idea. Traditional building materials seem more reliable and familiar. But we are talking about a foam plastic that has undergone a special treatment and its qualities are very different from the usual ones. The Japanese call their invention housing of the XXI century.

Old traditions and modern technologies

Geographically, Japan is located in a seismically dangerous zone. Since ancient times, the inhabitants of this country have made walls of residential buildings made of paper. The reason for this was not a deficit of stone and wood, but a constant threat of earthquakes. Therefore, for the Japanese, there is nothing unusual in the use of such lightweight materials during construction. The hemispherical shape is also not a novelty. The dwellings of the Eskimos and the Chukchi are very similar to the modern Japanese domed polystyrene domes. Today's technologies embody ideas from a distant past. The result looks like a real architecture of the future.

Design Features

The basic concept contains many fundamentally new approaches. Polyfoam is exposed to special effects and becomes much stronger than the one we are used to seeing in everyday life. In addition, it is treated with a special compound to reduce flammability and fire hazard. A more accurate name for this architectural creation is a house made of extruded polystyrene foam. Due to its light weight and dome shape, the building can be located even on a complex terrain and does not require a hard foundation. To install it, just align the round area and prepare an easy platform of sip panels. The component sections are manufactured industrially. The Japanese house from a foam plastic do not build, and collect from standard modules, as the children's designer. Work on erecting a building with a foundation diameter of 7-8 meters can be performed by several specialists within one day.

Economical

The authors of the idea emphasize the financial benefits of their project. Extruded polystyrene foam is one of the most cost-effective insulating materials. Its effectiveness makes a strong impression. According to the calculations of the manufacturers, walls from 100 to 190 mm thick can successfully withstand any weather conditions. The Japanese technology of a house made from foam plastic many times better preserves heat than traditional buildings made of silicate brick or concrete. This allows you to save money not only on heating the premises in winter, but also on cooling it in the summer. In some cases, energy costs, compared to buildings made from classical materials, can be reduced by 90 percent. Thanks to the modular assembly and the use of a relatively cheap foam, the cost of erecting a single-storey residential building may be surprisingly low. A budget of several thousand US dollars is enough.

Durability

The sun's rays have a devastating effect on domed houses. Projects and construction prices are different, but they always include a special coating. It absorbs ultraviolet, does not allow the foam to crumble and prevents erosion. The outer surface of the walls must be plastered and painted. This is done for decorative purposes, and for protection from the sun. Manufacturers recommend the use of a metallized coating based on aluminum. It is also considered effective to use polyurethane foam. At observance of all technological requirements the service life of a building can make 60 years. It is worth noting that the low water absorption of the material protects the dwelling from rain, snow and wet climate. Insects do not harm polystyrene foam. Also, it is not susceptible to rotting and corrosion.

disadvantages

Despite the fact that all components of the section are treated with a fire-resistant substance, a serious fire hazard remains. When burning foam generates a large number of toxic gases. Its strength is not sufficient to prevent hackers and penetration of intruders. In addition, living in a building completely made of synthetic material can adversely affect human health.

Versions

The total area of a standard one-story building is 50-60 m ² . Typical city apartments in terms of comfort do not exceed domed houses. Projects and prices are not limited to one basic option. Manufacturers offer a wide choice of interior design. At the request of customers, internal partitions and decorative walls are installed. A second floor can be built. If it is necessary to increase the area, construction companies erect and connect several buildings with crossings. It is important to note that the base price usually includes component sections, delivery, assembly and interior decoration. The supply of electricity and other communications will require additional costs. A Japanese foam house can serve not only as a living space, but also as a warehouse or an office.

European version

The idea of a hemispherical building from unconventional material attracted the attention of architects from Western countries. But European experts decided to use a stronger polystyrene concrete. According to the level of thermal insulation and resistance to rotting, it is not inferior to foam plastic. The disadvantage is the weight of this building material. The European version of the dome building is much heavier, which significantly increases its cost. The use of polystyrene concrete makes the installation process more difficult. A Japanese foam house can be assembled by several people without the use of any technique. In the western version, it is impossible to do without the help of a crane. In addition, a massive structure requires a more solid foundation.

Application

Quick assembly, the ability to install on a complex terrain and resistance to any climatic conditions make the Japanese foam house an almost ideal option for temporary housing for any purpose. In this case, the technology of domed buildings provides a high degree of thermal insulation and energy saving. With minimal financial costs for construction and operation, customers receive a level of comfort comparable to a city apartment.
