Trust in straw!

With LORENZ to project success!

Plan with straw! Build with LORENZ!

No two projects are alike. And yet learned processes are identical. With our partner network, expertise and efficient services, we lead you to project success.

Save time
with clarity
  • Unlike classic straw bale construction, our insulation systems made of wood and straw are delivered to the construction site already prefabricated. This saves an enormous amount of time during assembly and enables calculable cost planninIn addition, the construction site always remains clean and free of straw residues.
High planning flexibility
  • In addition to wall elements for new buildings or the subsequent insulation of existing buildings, we manufacture roof, angle and gable elements. Recesses for doors and windows are planned directly ex works on request. Special dimensions can be realized on request.
  • LORENZ products come from the factory according to planning - tailor-made in the desired construction depths. We offer the right system for every application - whether insulation or residential construction. The products are versatile and easy to install.
LORENZ relies on regional products and short delivery routes when purchasing materials. Thus, we ensure short delivery times and a minimal carbon footprint.
