More information about the product can be found in the current Pricelist or the Product Catalogue.


Thermal insulation ground bricks filled with expanded polystyrene laid on system thin-layer mortar designed for protected brickwork separating heated and unheated spaces, for insulated perimeter walls and for construction details.

FAMILY 2in1 ground clay blocks have the best thermal insulation properties on the market in comparison with other materials for single-layer masonry. Filling the cavities of these clay blocks with polystyrene increased their thermal insulation properties by 40% while maintaining their water vapour permeability. The FAMILY 2in1 clay blocks in widths of 440 mm and 500 mm meet the recommended values for passive houses without additional insulation.


  • best thermal insulation characteristics of the market, the heat transfer coefficient U up to 0.11 W/m2K
  • it can replace up to 36 cm of thermal insulation
  • with its thermal insulation properties it can replace a solid clay blocks wall up to 7 m thick
  • integrated insulation protected by ceramic
  • a comprehensive system solution for the building envelope in a single-layer structure
  • they meet the recommended values for passive and zero-energy houses with reserve
  • solid, safe structure
  • natural water vapour permeation - the brickwork breathes
