For the erection of a house can go from 5 to 8 weeks.

Summer - a natural time for construction. And you want to, and build faster and cheaper. So we decided to get acquainted with the technology for fast construction of the house, which is now touted as an alternative to traditional approaches. We compared their capabilities and costs during the construction of the box "cottage area of 120 square kilometers. m and "closing" of its roof and windows, and also learned the advantages and disadvantages. This helped us commercial director of "A. T. Megasfera Vladimir Kovalev, the chief economist of the firm "Prefabricated buildings" Alexander Pasechnik, marketing firm BlokMaster Yevgeny Shatalov, commercial director of "Module South Irina Zakalskaya, General Director of" Valkyrie "Alexander Burlachenko.

COTTAGES on the frame

Most of the new family homes in Canada, USA, Japan and several European countries are built on some variety of frame technology.

"Canadians." One of its variations - "Canadian" houses. First of timber is going hard and strong frame. Outside, he sheathed OSB-plate, with inner - gypsum board. Inside the wall is filled with insulation, for example, basalt wool or foam, resulting in its thermal insulating properties correspond roughly to two-meter brick wall. Internal communications are laid in the walls.

Panel frame. Another variation - so-called panel-frame technology. According to her house assembled from ready-made wall panels manufactured in the factory, which consist of outer and inner plates OSB, interlayer insulation, foil vapor and moisture protection.

SPEED OF ERECTION. When panel-frame technology itself Production Bundle for the cottage of 120 square meters. m at the plant takes 2-3 weeks. At the same time can stand and poured the foundation, which takes up to 4 weeks. Still no more than 1-2 weeks will be spent on proper installation of such a house. Total - 6 weeks. For comparison: the "box" is usually a two-layer brick house can be built for 10-12 weeks. But even a month or two will take on the insulation and final finishing of walls (plaster or drywall).

ADVANTAGES. The advantages, besides the speed of erection, can be attributed, and the relative cheapness of these homes: a house of 120 square meters. meters will cost from $ 25.8 thousand for comparison: the cost of the said brick "box" may be about $ 400 per square. m or $ 48 thousand for a house, not counting the cost of insulation and final finishing of the walls. Prefab homes do not shrink, so finishing work can begin immediately after installation at home. Such houses are very well hold heat, withstand dynamic forces, until an earthquake up to 9 points.

DISADVANTAGES. This is - a bad internal sound insulation and sealing the house (be sure to consider the ventilation system).

PERSONAL EXPERIENCE.
"Canadian house really a warm, live - comfortably, but I had to give up the habit of hanging on the wall that I need and where I want. It turned out that one can only hang out there, where it is provided. And just to hammer a nail into the wall can not obstruct the plasterboard to the wall very much not hang "- shares his experience, Alexander, a frequenter of a building forums.

TOTAL: 6 weeks.


COST. Erection of a closed "box" panel frame houses, taking into account the cost of preparing the foundation and roof covering, will cost between $ 215/kv. m. For the cottage area of 120 square meters. m is the range of $ 25.8 thousand

Wooden fram

.

Helpful. Wood is the most environmentally friendly building materials from

Wood as a building material is accompanied by a person in its history and is now experiencing another surge in his popularity. For log cabins, it can be used as follows: whole logs, logs, lumber and chopped laminated veneer lumber.

SPEED OF ERECTION. All you need for building a cottage in the 120 square kilometers. m log can be prepared for those 3 weeks until filled, and stand in the foundation. But she had assembled the box and the roof covering the house will take 3-4 weeks.

ADVANTAGES. These include low thermal conductivity (20-cm log wall protects from the cold as a brick wall thickness of more than a meter), especially with respect to homes from a simple timber. Unlike brick, wooden logs walls can withstand an unlimited number of cycles of freezing and thawing. Eco-friendly tree, able to "breathe" outside air filtering and outputting the pair that supports optimal microclimate in the house. These homes are going fast - especially from laminated veneer lumber. Finally, they themselves are beautiful and can live without walls, in particular, this applies to the buildings made of logs.

DISADVANTAGES. Wood fuel and prone to shrinkage, which can be delayed for a year and a half (and for the logs - and at 2-3 years) and up to 10%. Therefore, if you still plan to finish it will have to wait. Another possible trouble (especially if you have built not so qualified) - the appearance of cracks between the logs or timbers, and over time - and the cracks in the logs. True, laminated veneer lumber from these shortcomings spared. He can rot and eat insects, so every 3-5 years, the wall should be treated with chemicals or paint biozaschitnoy paint, which may take up to 20 thousand UAH.

PERSONAL EXPERIENCE. "In winter, warm keeping well. True, the heating had to drive at full capacity, and air in the room was very retain moisture. Then we were told that this is a common problem for wooden houses, and if your heat stove, preferably specifically humidify the air ", - says Natalya, survived the first winter in the house of chopped logs.

TOTAL: 6-7 weeks.

COST. Erection of a closed "box" from a simple timber costs about $ 300/kv. m, and from laminated veneer lumber - a $ 400-450/kv. m. That is, for the house at 120 square meters. m it will be $ 36 thousand and $ 48-54 thousand, respectively.

MODULAR HOME

.

Bodrenko. Of these "blocks" in the house is going for a few days

Vertex "technologizing" low-rise building for today are the so-called modular homes, which may consist of one or any number of modules. Module - it is like a cut "slice" of finished homes, rigid construction of the foundation, walls and ceilings, carries the fragment of the dwelling. The modules come with an already paved the engineering designs, windows and doors, exterior and interior trim, and even with the installed furniture and fixtures. Modules are fully manufactured at the factory and on site is only to build on pre-prepared foundation. In this case, according to experts, the restrictions on the architectural diversity of homes is not so great: a modular technology can be implemented most common places for our projects.

The maximum dimensions of the modules from different companies can be different, which can be determined and technological capabilities of the enterprise (eg, 4,5 * 12 m, 3 * 12 m, 3 x 8 m). Some manufacturers of floor panels, base and wall panels are made of cold rolled steel profiles. Plating is either galvanized corrugated sheet with a polymer coating. Other vendors in the foundation design put wooden beams, sheathed by plate OSB, as in frame houses. And in both cases the wall is insulated, like the "Canadian home."

SPEED OF ERECTION. Modules for home in 120 square kilometers. meters are manufactured at the plant within 2 to 4 weeks - both times while preparing the foundation. Building from one module is installed in 40 minutes, several - from one day to one week.

ADVANTAGES. When you create a modular home almost the entire building process is at work. This greatly reduces production time and reduces the cost of the total final cost, compared with traditional technologies. Also, it reduces to a minimum time of active work properly on the site of the customer.

DISADVANTAGES. The disadvantages include the limitation of technology to high-rise building - no more than 2 floors. The second disadvantage - Ships overall modules and operating them requires adequate access roads and space for equipment.

PERSONAL EXPERIENCE. Modular homes have not yet become widespread, and we could not find the person who would have shared the experience of living in a house.

TOTAL: up to 5 weeks.

COST. The cost of modular homes range from $ 220/kv. m, depending on the trim and filling. That is 120-meter cabin will cost from $ 26.4 thousand

HOUSE OF foam-and gas-concret

.

Porous. The large size and easy to make it easy to block

Houses are built and from blocks of hardened concrete "foam" - the so-called foam-and aerocrete. It is porous, relatively lightweight material, the hardness close to the tree, from which easily handled cutting tool.

SPEED OF ERECTION. Construction is simplified through the large size aerated concrete block and its low weight. Therefore, the box home area of 120 square kilometers. m can be constructed for about 8 weeks, taking into account the time to prepare the foundation and construction of the roof.

ADVANTAGES. These homes are good high thermal protection (heating costs 3-4 times less than the brick house of the same area). Further, foam - an eco-friendly material, this is second only to the tree. In addition, the wall of porous concrete is easy to drive a nail to hang up on her shelf.

DISADVANTAGES
. Aerated concrete has high water absorption, so the outer surfaces of the walls are composed of aerocrete, must be protected from precipitation. In addition, the strength gradually and aerated still inferior to conventional concrete or brick,

PERSONAL EXPERIENCE. "Nice house, but one piece of advice - accurate to the walls. So, inadvertently, the hammer broke off a piece "- this warning can be found on the Internet.

TOTAL: up to 8 weeks.

COST. Erection of "boxes" of foam block or aerocrete with the foundation and the roof can pull the $ 250-300 / sq. m or the 120-foot home - $ 30-36 thousand

TERMODOM

 

.

Durable. The house will be a monolithic

The walls are built of light termodoma hollow polystyrene blocks (thermal blocks), playing the role of permanent form. Filled with concrete, they form a monolithic wall thickness of 150 mm, insulated on both sides of 50-mm Styrofoam plate. Fuser length - 1 m, width and height - 25 cm blocks of special design locks in quickly and accurately link them as elements of design "LEGO".

SPEED OF ERECTION. During the construction of the cottage is 120 square meters. m on the foundation, walls and roof will take a maximum of 2 months.

ADVANTAGES. Walls are erected quickly without lifting mechanisms. To work does not need a qualification mason enough that people knew how to use the level and how to prepare concrete, so a house can be constructed independently.

Heating costs termodome 2-3 times lower than in the brick building of the same area, and it can not sink down to reduce the temperature of outside air to 0-5 ° C.

Construction thermoblocks (provided they are of high quality) can fold completely flat wall. Therefore, any kind of interior and exterior decoration does not require prior alignment of the surface.

DISADVANTAGES. The disadvantages include a very low water vapor permeability of walls, leading to increased humidity. In addition, the EPS layers are not very resistant to mechanical damage.

PERSONAL EXPERIENCE. From the experience of forum regulars: "With what a story - so it's to hang a shelf. On polystyrene her not to touch, so you have to beat these "pits" through it in concrete. And no need to save on the ventilation system, air conditioning in the winter in the fight against humidity is not an assistant. "

TOTAL: 8 weeks

COST. On technology "Thermo" erection of the box, taking into account the cost of preparing the foundation and cover the roof would cost about $ 300-350/kv. m. For the cottage area of 120 square meters. m it will be $ 36-42 thousand
