HELUZ Family 2in1 are filled with a patented method of polystyrene balls and have the best thermal insulation properties on the Czech market compared to other materials for single-layer masonry. This unique material increases the thermal insulation properties of the brick by 40% while maintaining its vapour permeability, which is important for healthy living. 
HELUZ FAMILY 2in1 grinded hollow clay block are suitable for single-layer external walls of zero, passive, low-energy houses without the need for insulation. 
FAMILY 2in1 bricks with a width of 500 mm meet the recommended values for passive houses without additional insulation.

• Without the need for additional insulation
• Energy efficient. Keeps warm in winter. Cool in summer. No unnecessary heating/cooling of the house
• Building for the next generation
• Complete building system from one manufacturer (perimeter, interior and supplementary bricks, lintels, ceilings, panels, chimneys, mortars)

Replaces up to 36 cm of thermal insulation. On the other hand, even if the building envelope is well insulated, it is a functional solution for a maximum of 30 years. After a certain period of time, the façade will therefore have to be demolished and a new one installed. However, in the case of the use of insulated bricks (HELUZ FAMILY 2in1), the reconstruction of the building envelope is not necessary. Brick buildings have an excellent service life of 180 years or more; it is a solid and safe construction that you can rely on 100%. High stability, strength, mechanical resistance and dimensional stability are common arguments for choosing brickwork as the basic building material of a new house.

A properly designed building, constructed with building components from a single manufacturer, achieves high homogeneity and therefore better thermal insulation parameters. The use of building components from one manufacturer simply results in better performance of the whole building.

The technology of single-layer masonry construction made of baked bricks must be taken into account from the initial planning stage of the project, so that all the principles of correct design - designing in a module, observing the required clearances of building openings and room clearances - are simply observed.

 „V zimě drží teplo uvnitř a naopak v létě zase venku, a to bez dodatečného zateplení. Neotvíráme okna, přesto máme doma krásný vzduch, a to díky efektivnímu větrání, které obstará rekuperační jednotka. Kombinace cihel HELUZ FAMILY 44 2in1, rekuperační jednotky a tepelného čerpadla se stará o vysoký komfort bydlení, přitom náklady na teplo jsou super nízké." Majitel - více zde.
