Hybrid construction with clay blocks combined with brick - reinforced concrete - aerated concrete - sand-lime brick - cement block construction as a structural load-bearing element. The breakthrough in hybrid construction is within reach without wood.

I am delighted to be able to present you with further fascinating details on this pioneering construction method, which will pave the way for multi-storey construction.

The key lies in the combination of statically load-bearing elements made of bricks, reinforced concrete or innovative prefabricated aerated concrete elements with a lining of high-performance clay bricks as insulating and soundproofing bricks. This innovative concept offers enormous advantages over conventional construction methods.

The load-bearing columns and skeletons provide high structural integrity for multi-storey buildings. The use of your clay blocks in the additional wall lining massively improves the overall energy efficiency of the building. Modern insulation concepts with renewable fiber materials complement the impressive energy and CO2 savings.


Studies show that a hybrid concept with up to 70% highly insulated clay blocks is possible. This allows CO2 emissions to be reduced by up to 40% compared to conventional construction methods. The hybrid construction method also offers considerable advantages when it comes to subsequent disposal, with up to 80% lower energy costs and CO2 pollution.

In addition, the integration of wall heating or wall cooling directly into your clay brick lining or support panels enables a comfortable and energy-efficient indoor climate. This innovative concept can be used worldwide - whether in cold or warm regions. Wall heating and cooling offers outstanding user comfort in all climate zones.

Clay earth has a number of interesting and useful properties as a building material:

  • Heat-storing: clay has a high heat capacity and can store heat for a long time. This will improve the energy efficiency of buildings.
  • Moisture-regulating: Clay can absorb and release moisture. This ensures a pleasant indoor climate and prevents mold growth.
  • Sound-insulating: Clay walls have good sound insulation and therefore contribute to soundproofing in buildings.
  • Breathable: Clay building materials are vapor-permeable and allow moisture exchange between rooms and the outside climate.


To make the most of these innovative possibilities, close cooperation across the entire value chain is crucial. I therefore propose that representatives from the following areas be brought together in the near future:

  • Property developers and investors from the housing sector
  • Architects and planners who want to drive the topic forward
  • Manufacturers of bricks, concrete elements and your clay blocks
  • Specialist planners for building services and insulation systems

Together we can then discuss the concrete implementation, economic viability and marketing of this innovative construction method and determine the next steps.

I am very much looking forward to taking this exciting topic forward with you and potential partners from the industry. Let's arrange an appointment for an initial meeting as soon as possible.
