Affordable, good or fast? As a rule, when building a house, we can choose only two of the listed options, especially in the case of wall materials. Until recently, their choice was small - aerated concrete (gas silicate), wooden beams, silicate or ceramic solid bricks in combination with insulation. And the rule of "two options" has always worked for them. Fortunately, progress does not stand still, and large-format ceramic blocks or ceramic blocks appeared and began to be widely used in the world. Their outstanding representative is the innovative Porotherm family, developed by Wienerberger, the world's leading manufacturer of ceramic building materials. For the first time, ceramic blocks in construction began to be used in the 70s of the last century in Europe, and only in the early 2000s, the technology of building houses from ceramic blocks came to Russia. What is the difference and what are the advantages of the new large-format ceramic blocks in comparison with the usual aerated concrete, brick and wood, and why do they allow you to combine high performance, speed of construction and availability? It's all about design and material!
Warmly
Porotherm has outstanding thermal performance characteristics that exceed those of traditional materials. For example, in order to achieve thermal insulation properties comparable to Porotherm 38 Thermo (wall thickness 38 cm), the thickness of a wall made of ordinary brick should be 235 cm, and from aerated concrete with a density of D500 - about 48 cm.
Porotherm 38 Thermo has these unique thermal insulation properties due to the new, more efficient HV shape of the voids and increased porosity of the ceramic shard. Porization itself appears due to the peculiarities of Porotherm manufacturing: small wood particles are added to the clay. Burning out during firing, they form a network of closed microcapillaries, which not only store heat, but also improve the microclimate - the walls "breathe".
Wall thickness that allows you to achieve heat transfer resistance Ro = 3.24 (m2 * C) / W. This indicator meets the requirements for thermal protection of external walls practically throughout the entire European territory of Russia (in accordance with SNiP 23-02-2003 "Thermal protection of buildings").
Availability and speed of building walls at home
It is often considered that building with ceramic blocks is expensive compared to aerated concrete and traditional bricks. This is because only the cost of wall materials is compared. For example, the retail price of aerated autoclaved concrete varies within 3000-4500 rubles / m3, and the price of warm ceramics is 4000-5000 rubles / m3, the difference is noticeable. However, it's all about the details, if you count the construction costs as a whole, then the price difference between these materials is leveled.
Ceramic blocks Porotherm VS aerated concrete:
- masonry from a large-format ceramic block does not require reinforcement and the construction of monolithic reinforced concrete belts, which takes at least 30 days;
- finishing work can be started almost immediately after the walls are erected, because do not require long drying;
- high thermal insulation properties, which make it possible to do without wall insulation.
Ceramic blocks Porotherm VS traditional bricks:
- groove-comb connection optimizes the cost of additional materials - vertical seams are not filled with masonry mortar and its consumption is reduced by 30%;
- one block replaces from 10 to 14 bricks in the masonry, which significantly speeds up the process of wall erection;
- reduction in labor costs in comparison and savings on payment for work - a worker will need three times more time when laying bricks, therefore, you will pay three times more to the foremen for the work;
- the frame of an individual residential building made of ceramic blocks can be erected in two weeks without the use of complex construction equipment;
- high thermal insulation properties, which make it possible to do without wall insulation.
As a result, the cost of a ceramic block house in comparison with gas silicate does not exceed 5%, with obviously better performance. You can calculate the number of blocks and their cost for the area of your future home using the Porotherm calculator.
