Easy to cut – EBB clay boards

 Product Data Sheet EBB clay boards

 German Fire Testing Certificate PB Feuerwiderstand EI45 extern-1

The Eco Building BoardsTM are a practical alternative to gypsum plasterboards. They combine the advantages of drywall construction for internal walls and ceilings with the amazing properties of clay as a „green“, healthy and versatile material. The Eco Building BoardsTM add significantly to the thermal mass of a structure and passively optimize the relative humidity of the internal climate to around 50% rh, by acting as a moisture buffer.

The ideal solution for ‘passive houses’ or as a supplementary heating source in any house. The combination of loam/clay and carbon technologies has enabled the development of a high-tech heating element which fulfils all the demands of modern temperature management.
