Sustainable materials

For our sound absorbers, we mainly use natural wool from sustainable sources because wool naturally has excellent properties for a pleasant room and working climate and, unlike plastic foam, is 100% biodegradable. Our acoustic modules are made from Swiss and South German pure new sheep's wool. The surface is made of high-quality loden, while the back and core consist of wool layers of different densities, fibre orientation and fibre fineness. The manufacturer from whom we source the wool works according to the zero-waste approach, which begins with the collection of the wool, where all wool is accepted from the sheep farmers. Even the leftovers are swept up and later pressed into organic fertiliser pellets. Scraps of wool from fleece production are fed directly back into the production process.

For our polycarbonate opal diffusers, we use polycarbonate that is made from 59% pine oil, a waste product of the timber industry, and is certified according to the ISCC mass balancing principle.
