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


Thermal insulation ground bricks laid on system thin-layer mortar designed for protected single-layer and insulated perimeter brickwork of nearly zero-energy buildings.

FAMILY ground clay blocks have the best thermal insulation properties on the market in comparison with other materials for single-layer walls without filled out cavities. FAMILY clay blocks possess one of the most elaborate clay blocks block geometries, which minimizes heat transfer while maintaining high strength.


  • best thermal insulation properties in the category of unfilled clay blocks suitable for low-energy and passive houses, heat transfer coefficient U up to 0.14 W/m2K
  • cost-optimal variant, i.e. investment in the brickwork in proportion to its return is the highest
  • comfortable room micro-climate
  • a comprehensive system solution for the building envelope in a single-layer structure
  • a good prerequisite for obtaining the label for low-energy and passive houses
  • solid, safe structure
  • natural water vapour transmission - the brickwork breathes
