Resource-efficient materials

For our sound absorbers, we mainly use natural wool from Switzerland and southern Germany because wool naturally has excellent properties for a pleasant indoor and working environment and, unlike synthetic foam, is 100% biodegradable. Our acoustic modules are made from sheep’s wool sourced in Switzerland and southern Germany. The surface is made of high-quality loden fabric, while the backing and core consist of layers of wool with different densities, fibre orientations and fibre finenesses. The manufacturer from whom we source the wool follows a zero-waste approach that begins at the wool collection stage, where all wool from the sheep farmers is accepted without exception. Even remnants are swept up and later processed into organic fertiliser pellets. Wool remnants from the production of nonwoven material are fed directly back into the production process.
