Building material made of cattail (Typha)
Due to the special structural properties building materials can be produced offering a combination of insulation and strength, which is unique on the market. The leaf mass of typha is especially suited to produce innovative building materials due the structure of the plant. The leaves have a fiber-reinforced supporting tissue filled with soft open-cell spongy tissue providing for amazing statics and an excellent insulating effect.
In the past few years, the Fraunhofer Institute for Building Physics investigated various product developments in laboratory as well as outdoor test facilities of in cooperation with the researcher Dipl.-Ing. Werner Theuerkorn. In the course of the research a variety of interesting products were developed of which a mineral-bound isotropic material for board production is of significant importance.
