The Grape Matrix acoustic wall covering is based on the idea of avoiding waste in connection with the production of other acoustic products in PET felt. Thus, the starting point was that smaller elements should be able to be added to the unused space when the felt for other designs had to be cut. In this way, in relation to material consumption, a free multi-coloured stock of wall elements can be built up. The decorative acoustic wall in the pictures is the variant where a single raw panel of 180 x 240 cm is used optimally. The only other material we have added is the three screws used for the suspension.
