The heat diffusion coefficient values “U” are given with plasters for the production plant in Hevlín at the strength 8 MPa or 10 MPa and thermal insulation mortar or mortar for full-area thin joint Heluz with ground bricks, if not mentioned otherwise.


For single-layer perimeter walls of zero-energy, passive, low-energy and energy-efficient buildings.

FAMILY 2in1 ground bricks have the best thermal insulation properties on the market in comparison with other materials for single-layer masonry. Filling the cavities of these bricks with polystyrene increased their thermal insulation properties by 40% while maintaining their water vapour permeability. The FAMILY 2in1 bricks 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 brick 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
