The most important thing for the house - this is the material from which it is built. From the choice of material depends on price, performance and durability of the structure. Ideal materials exists. Each has its pros and cons, and we will tell about them. There are three basic material from which to build houses in Ukraine: wood, brick, concrete. All else - it numerous variations and combinations involving these three components.
Let's start with the traditional Ukrainian house-building material - wood. From it we have built about 23% of homes. A wooden house can be built of logs (rounded or profiled) or timber (simple or laminated). Log homes are cheaper than houses of timber. The most expensive material - laminated board.
Pros wooden house - a beautiful appearance, environmental, frost resistance, speed of construction, seismic and wind resistance. In addition, wood does not require additional cladding (a good saving for the budget).
Cons too, but they are relatively few. First, the tree - whimsical material. For example, wooden houses often shrink. Shrinkage houses - is a natural process of change of volume of the walls due to drying of the material from which they are made. Maximum shrinkage of about 10% is observed in the houses of freshly cut logs. Such a building is necessary to stand without finishing no less than 8 months, and usually - a year. In the process of shrinking the house can go cracks that coat with special structures. Minimal shrinkage observed in the houses of laminated veneer lumber and conventional kiln dried lumber. Such materials are almost immediately ready for finishing. However, house warming will take a lot of timber resources. Another shortcoming of the tree - flammability, fire can destroy a building in minutes. Therefore, wooden houses impregnated with special compounds that increase their fire. Special formulations are necessary for protection against decay and insects. Impregnation - a necessary measure, but non-lethal weapons themselves are not always harmless. In addition, the house of the forest requires constant care, especially if it is for a seasonal residence, it should definitely heat thoroughly, as damp wood begins to rot. In general, the durability of wooden houses built by experts in compliance with all technological nuances of 70-100 years.
One of the most popular on the market is considered brick material. More than 50% of houses in Ukraine were built of brick. In the construction used two types of bricks: lime (white) and ceramic (red) brick. Silica brick is a mixture of quartz sand, water and air exhaust. It is quite durable, resistant to frost, has good sound insulation. However, for the construction of external walls of construction crews prefer ceramic bricks. Available in seven brands of ceramic bricks: from the M75 to the M300. The higher the number, the stronger the bricks. You should also pay attention to frost, denoted by the letter F. The lowest quality - F15, the highest - F75.
The main advantages of brick - it's strength, fire resistance, a wide range of the market and reasonable price. A small brick house can sometimes be cheaper than wooden cottage. Brick is well hold the temperature, in this sense, it is ideal for houses where the planned year-round residence. But at the same brick on heat transfer seriously inferior to the tree.
Deficiencies have also missing bricks. To build a brick house at times it is necessary to spend one and a half times longer than the erection of a wooden house. Brick - it is a heavy material, which complicates its logistics and storage. For brick building needs a strong and solid foundation, and that the additional cost.
Foam and concrete
In recent years become increasingly popular home cellular concrete, or as it is called, foam. There are several types of such concrete (foam concrete, aerated concrete, expanded clay, styrofoam) are used in the form of blocks.
His popularity has earned foam thanks largely to its budget cost, speed of execution of work, light weight. Since the foam has a porous structure, the weight of the foam blocks is greatly reduced, thus laying house goes faster.
The walls are made of porous concrete as opposed to brick breathable. Due to this property of the material in a residential area is constantly supported optimum humidity, eliminates the appearance of mold and mildew. Aerated concrete does not rot and infestation of insect pests.
This "breathing" walls are badly combined with high humidity. During the years of operation of aerated concrete gains sufficient moisture, syreet, thereby increasing maintenance costs. Failure to construction technology is the porosity can lead to the destruction of the house. The moisture that accumulates in the pores of the foam, when it freezes and increases in volume leads to cracking.
A more modern version of the commercially available building blocks - it is aerated. During manufacture, it is dried in an autoclave, thereby relieving, the main deficiency of cellular concrete.
