Licensed technology

The technology is a combination of polystyrene concrete and a steel or lumber frame structure. Polystyrene concrete is used in structural elements in the form of panels of different sizes, and in bulk form. The polystyrene concrete and the frame structure create a homogeneous, thermal bridge free building.

Advantages of the Löglen Construction Technology

The insulation of Löglen buildings is outstanding. According to measurements taken in an accredited laboratory the heat transfer coefficient of the 41 cm thick Löglen standard wall is U= 0,21 W/m2K. The system does not require additional insulation, since the material of the entire building provides the excellent heat retention and insulation values. Consequently, Löglen buildings achieve the energy-saving qualification.

The Löglen wall structure „breathes” and it has very good vapor diffusion, thus creating a healthy and pleasant atmosphere in the buildings (µ=7-10), the generated vapor escapes through the walls without a problem and does not cause harmful molding or mycosis on the internal wall surface, due to the thermal bridge free structure.

The weight of Löglen wall structures is 300 kg/m3, considered ideal by architects (300-500 kg/m3). The ideal weight means 10-40% of the concrete saved when building the foundations. The construction set of Löglen technology possesses fire safety certificates that comply with the regulations. The great formability of Löglen technology provides a wide range of possible uses. Löglen technology is Eco-friendly, Löglen houses are reusable.

INSULATION OR LÖGLEN?

What is most important in the case of a flat or a house is that its inhabitants have an excellent feeling of comfort. This depends on many things, but arguably the proper thermal comfort is the basis of everything.

More simply: a good home in spring and summer is cool, in autumn and winter is warm. In any case, in spite of the weather, we must assure the best temperature and thermal comfort inside.

To achieve this, thermal insulation is required. In winter we must prevent as much as possible the buildings internal heat generated by the outflow, so we must reduce the loss of heat and in summer should happen just the opposite.

For those who have already finished building, there is not much choice, the insulation must be resolved subsequently. For these, there exist various materials and solutions. There is good, very good, and there is LÖGLEN!

GOOD: polystyrene board (EPS), mineral wool and glass woo

During the manufacture, the air is closed into the polystyrene cells, for this reason has good insulating properties. Polystyrene is the cheapest facade insulation material in the market.

The mineral and glass wool reaches the insulation property by closing the air into its fibers.Good features of fibrous insulated materials: fire resistance, high heat insulation and sound insulation.

VERY GOOD: polystyrene foam concrete board

Itself has excellent thermal insulation properties, it can also be used as a follow-up insulation.

THE BEST: polystyrene concrete (LÖGLEN)

It is not needed subsequent thermal insulation, as long as the wall is made from the combination of polystyrene concrete and steel frame. This is the LÖGLEN system!

Due to its extremely high insulating properties do not require additional insulation, as the wall is made of high insulation material. As a result, the LÖGLEN buildings are of increased low energy.

How is it made?

Conform to the experiments made, with the LÖGLEN masonry can be reached a 50-80 % energy save compared with the traditional bricks or concrete made buildings. Due to its excelent thermal features, it received the “A+” energy classification, which is the best category.( U=0,185 - 0,21 W/m2 )

For buildings it is issued energetical certificate for this classification.

This is such a certificate which evaluates the building energetical quality and the authentic information has a primary role.

We can get the following informations from this certificate:

• The energy class of the building
• How much is the building's annual energy consumption (heating, cooling and hot water supply, ventilation)
• How good is the insulation of the building, orientation

In Hungary, the buildings and homes are currently classified into 10 classes, depending on the energetic qualities. The energetic basis of the classification is carried out to the building's actual energy consumption requirements of the prescribed percentage, ie 100%.

For example, at a H category building,with a 300% energy consumption, this means that compared to today's standards the building consumption is thrice. At the A + classification, eg. LÖGLEN the building's energy consumption is up to 55% of the standards.

For example: heating demand for a 100 square meters house:

• Lightweight house: average 9 to 11 kW
• Traditional brick built house: average 18 to 25 kW
• Löglen: average 3-4 kW

The wall heat transfer coefficient characterized insulating ability (U = W/m2K). The lower the value, the better the heat insulating structure. In Hungary the standard is U=0,7 W/m2 K for detached houses. If the U is between 0,3 and 0,1, we can say the building insulation is excelent.
