In today's housing trends are increasingly called low-energy and passive houses. They operate on the principle of using heat gain in the building. They are the external passive solar gains and internal gains, which belong to the heat emitted by people and appliances. The high quality of insulation and other elements of these profits "do not run out" for most of the year, sufficient to maintain a comfortable room temperature.
Common brick is no longer in the course, replace it with a sandwich systems
As is becoming the new trend of energy saving and low energy consumption buildings, gaining in popularity technically advanced building materials. These, compared with traditional clay brick, which can be found in a number of buildings built in the last century, excel in better insulation properties. In this regard, they are very popular so-called sandwich systems, often combining calcareous masonry and insulation material. "This combination of building material and the insulating material. The supporting layer of perimeter walls, which will handle the transfer of static load is added appropriately selected insulating layer. This achieves optimum heat insulation properties and eliminating possible thermal bridges, "describes Martin Urbanec (KM Beta). In principle, the sandwich brickwork combine a variety of suitable building and insulating materials, in general, it is worth reaching for the comprehensive system, the use of which is likely to yield better results than a random combination of masonry and insulators.
More space in the house through the walls subtilnějšímu
In earlier times it was not uncommon that the outer wall has a thickness of eighty or more centimeters. Not everyone had land enough space to simply build larger, and therefore a wide masonry generally detracts from the interior living space. Use of modern and technologically advanced construction elements, however, today, instead spending the built-up area for the benefit of the living. "Sandwich lime masonry achieves the required thermal insulation, acoustic and static properties at significantly lower wall thicknesses. This leads to significant savings in built-up areas - at stometrového apartment living space increases up to eight square meters, "says the expert.
Heat accumulation similar to the medieval castles
In addition to the thermal protection of buildings today, interested investors and developers also the question of the so-called thermal mass. It is a parameter that is especially useful for owners of low-energy and passive houses, where the emphasis is on slow cooling down indoors when the heating breaks in the winter and the warming influence of external sources of heat in the summer. Now these results are achieved by using a combination of concrete blocks with high heat accumulation and high quality insulation. From comparison of various kinds of materials published in this regard as the winner of sand-lime brick, which is due to higher volume weight up to twice the thermal mass compared to traditional clay bricks. Use of materials with high thermal accumulation is not a novelty in the construction industry - a similar, albeit very imperfect principle is also heated by medieval castles. Its thick stone walls of stone blocks with a high bulk density effects of the sun and internal resources first, "drew as" a lot of heat, and then the long hours and days turn discharged into the interior. Lack of quality insulation - which is a necessity for today's construction - but caused significant heat loss.
Tongue and groove - building a puzzle
Compared to previous years, in addition to technological advances in the field of building materials and their properties significantly accelerated and the construction itself. "Masonry units are now generally regarded tongue and groove. For the bonding of the cement high-strength adhesive mortar for masonry and thin coats with a loading area. Through the use of adhesives is also degraded by the wet process of applying mortar, so that not even need to leave the building through the winter so called vymrznout, "explains Martin Urbanec. Another advantage in addition to the speed of construction is then, according to him, the fact that the wall near the present-day buildings are very precise and smooth, plaster and can therefore be applied as a thin film. This of course raises another both time and financial savings.
