Summer - a natural time for construction. And they want to, and build faster, and cheaper. So we decided to become acquainted with the technology quickly built houses, which are now advertised as an alternative to traditional approaches.
We compared their capabilities and costs when building "box" cottage area of 120 square meters. m and "closing" of its roof and windows, as well as learn the advantages and disadvantages. This helped us commercial director of "A. T. Megasfera Vladimir Kovalev, the chief economist of the firm "Prefabricated" Alexander Pasechnik, marketing firm BlokMaster "Eugene Shatalov, commercial director of" Module South Irina Zakalskaya, General Director of "Valkyrie" Alexander Burlachenko.
COTTAGES on the frame
Most of the new family houses in Canada, USA, Japan and several European countries are built on some form of frame technology.
"Canadians". One of its variations - "Canadian" home. First of timber is going hard and strong frame. Outside, he edged OSB-plate, with the internal - plasterboard. Inside the wall filled with insulation, for example, basalt wool or foam, resulting in its insulating properties are roughly equivalent to two-meter brick wall. Internal communications are laid in the walls.
Panel frame. Another variety - so-called panel frame technology. At her house is going out of the finished wall panels, manufactured in the factory, which consist of outer and inner panels OSB, interlayer insulation, vapor film and moisture protection.
Rapid construction. When panel-frame technology but the production set for the cottage on 120 square meters. m at the plant takes 2-3 weeks. At the same time can be filled and stand in the foundation, which takes up to 4 weeks. Not more than 1-2 weeks will be spent on proper installation of such a home. Total - up to 6 weeks. For comparison: "box" is usually a two-layer brick house can be built for 10-12 weeks. But even a month or two will go to heating and final finishing of walls (plaster or plasterboard).
ADVANTAGES. The advantages, besides the speed of erection, can be attributed, and the relative cheapness of houses: a house of 120 square meters. meters will cost from $ 25.8 thousand for comparison: the cost of the said brick "box" can make about $ 400 / sq. m or $ 48 thousand for the house, not counting the cost of heating 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 loads, up to an earthquake up to 9 points.
DISADVANTAGES. This is - a bad internal sound insulation and sealing the house (sure you need to consider the ventilation system).
PERSONAL EXPERIENCE. "Canadian house really a warm, live - comfortably, but I had to give up the habit to hang on the wall that I need and where I want. It turns out that you can hang just where it is provided. And just to hammer a nail into the wall can not obstruct the drywall on the wall very much not hang "- shares his experience, Alexander, who frequented one of the building forum.
TOTAL: up to 6 weeks.
COST. Erection of a closed "box" panel-frame house, with the cost of preparing the foundation and cover the roof, will cost from $ 215/kv. m. For the cottage area of 120 square meters. m is a range of $ 25.8 thousand
Wood as building material accompanies man in its history and is now experiencing another surge in his popularity. For log cabins may be used as follows: whole logs, logs, chopped logs and laminated beams.
Rapid construction. Everything you need to build a cottage in the 120 square meters. m log can prepare for those 3 weeks until filled, and stand foundation. But she assembled "box" and cover the house roof takes 3-4 weeks.
ADVANTAGES. These include low thermal conductivity (20-cm log wall protects from the cold like a brick wall thickness of more than a meter), especially with respect to houses from a simple timber. Unlike brick, square log walls can withstand an unlimited number of cycles of freezing and thawing. Wood environmentally friendly, able to "breathe", filtering out the external air and driving a pair that supports optimal microclimate in the house, wrote today. These homes are going quickly - especially from a laminated board. Finally, they themselves are beautiful and can do without finishing the walls, in particular, this applies to buildings of logs.
DISADVANTAGES. Wood fuel and is prone to shrinkage, which may take 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 built not very skilled) - the appearance of cracks between the logs or timbers, and over time - and cracks in the logs. However, laminated board from these shortcomings spared. He can rot and eat insects, so every 3-5 years, the walls need to handle chemicals or paint biozaschitnoy paint, which may take up to 20 thousand UAH.
PERSONAL EXPERIENCE. "In winter, the heat was kept very well. However, heating had to drive at full capacity, and the air in the room was very retain moisture. Then we were told that this is a common problem for wooden houses, and if the heat is not heating, preferably specifically humidify the air ", - says Natalya, who survived the first winter in the house of chopped logs.
TOTAL: 6-7 weeks.
COST. Erection of a closed "box" from a simple timber would cost about $ 300/kv. m, and a laminated veneer lumber - in $ 400-450/kv. m. That is for homes in 120 sq. m it will be $ 36 thousand and $ 48-54 thousand, respectively.
The top "technologizing" low-rise building for today are the so-called modular homes, which may consist of one or some number of modules. Module - is how to cut "slice" finished house, the rigid construction of the foundation, walls and ceilings, carries the fragment of the dwelling. Modules come with already laid the engineering designs, windows and doors, exterior and interior decoration and even with the established furniture and fixtures. Modules are manufactured entirely in the factory and construction site is only their assembly 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.
Maximum size of modules from different manufacturers may be different, which can be determined and technological capabilities of enterprises (eg, 4,5 * 12 m, 3 * 12 m, 3 x 8 m). Some manufacturers slabs, foundation 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, edged slab OSB, as in the frame houses. And that, in both cases the wall is insulated, like "Canadian home."
Rapid construction. Modules for homes in 120 sq. meters are manufactured at the factory within 2 to 4 weeks - just before preparing the foundation. Building from one module is mounted for 40 minutes, several - from one day to one week.
ADVANTAGES. When you create a modular home is virtually the whole construction process is at work. This greatly reduces production time and reduces the cost of the total final cost, compared with traditional technologies. It also reduces to a minimum time of active work on the actual site of the customer.
DISADVANTAGES. The disadvantages of technology may include restrictions on high-rise building - no more than 2 floors. The second disadvantage - Ships marker modules and operating them requires adequate access roads and space for equipment.
PERSONAL EXPERIENCE. Modular homes, we have not yet acquired a wide distribution, and we could not find anyone who would share experiences of living in a house.
TOTAL: up to 5 weeks.
COST. The cost of modular homes from $ 220/kv. m, depending on the interior and filling. That is 120-meter cabin will cost from $ 26.4 thousand
HOUSE OF foam and aerated concrete
Houses being built also from the frozen blocks of concrete "foam" - the so-called foam-and gas blocks. This is a porous, relatively lightweight material, hardness close to the tree, from which it is easily cut.
Rapid construction. Construction is simplified through the large size of foamed concrete blocks and its light weight. Therefore, Box 120-square home. m can be built for about 8 weeks, given time to prepare the foundation and construction of the roof.
ADVANTAGES. These homes are good high heat protection (heating costs by 3-4 times less than that of a brick house is the same area). Further, foam concrete - environment-friendly material, in that he concedes only a tree. In addition, the wall of porous concrete is easy to drive a nail to hang up on her shelf.
DISADVANTAGES. Aerated concrete has a high water absorption, so the external surfaces of the walls are composed of gas blocks, must be protected from the effects of precipitation. In addition, the strength of foam and aerated still inferior to conventional concrete or brick,
PERSONAL EXPERIENCE. "A good house, but one piece of advice - beware of the walls. So, inadvertently, the hammer pulled the piece "- a warning can be read on the Internet.
TOTAL: up to 8 weeks.
COST. Erection of "boxes" of foam blocks or gas blocks to the foundation and the roof can pull $ 250-300 / sq. m or 120-foot home - $ 30-36 thousand
The walls are built of light termodoma hollow polystyrene blocks (thermoblocks), playing the role of permanent shuttering. Filled with concrete, they form a monolithic wall thickness of 150 mm, insulated on both sides of 50 mm EPS plate. Fuser length - 1 m, width and height - 25 cm blocks of special design locks quickly and accurately connect them as elements of design "LEGO".
Rapid construction. When building a cottage in the 120 square meters. m on the foundation, walls and roof will take a maximum of 2 months.
ADVANTAGES. Walls are built quickly, without lifting mechanisms. For do not need qualifications mason enough that people knew how to use the level and how to prepare concrete, so a house could be built independently.
Heating costs in 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.
Constructive thermoblocks (provided they are of high quality) you can fold completely flat wall. Therefore, any kind of internal and external finishing does not require prior alignment of the surface.
DISADVANTAGES. The disadvantages include a very low permeability of the walls, leading to high humidity in the room. In addition, the EPS layers are not very resistant to mechanical damage.
PERSONAL EXPERIENCE. From experience forumnym regulars: "With what a story - so it is to hang a shelf. In polystyrene it is not hooked, so it is necessary to beat these "pits" through it in concrete. And no need to save on the ventilation system, air conditioning in the winter to combat humidity is no help.
TOTAL: 8 weeks
COST. Using the technology of "Thermo" construction "box" to the cost of preparation of foundation and cover the roof would cost about $ 300-350/kv. m. For the cottage area of 120 square meters. m for a total of $ 36-42 thousand
