A Swiss SME is searching for either a board manufacturer or a research & development partner that is able to produce or to develop an open-pore, air-permeable, non-flammable or flame retardant, lightweight board. The board size is rather big, namely approximately 3.0 m x 1.2 m. The semi-finished product can be delivered from anywhere in the world and will be finished, processed and distributed by the Swiss SME. The product can be redeveloped or be an already existing board material that will be delivered to them. Alternatively, an R&D partner could help to develop the semi-finished product and another company could produce the boards for the Swiss SME (in a license and/or secrecy order). The finished product will be used in the general building industry.
