Kiø framed acoustic panels are made out of repurposed textile felt and upcycled discarded wood from a major Danish contractor. The textile felt used for Kiø is produced from worn-out workwear that can no longer be used for clothing or in other secondary clothing production. We have developed a method of sorting, where we acquire pure, clean fractions, which ensures the high quality of the end product. After sorting, the fabric is shredded; going from a woven material to becoming small, short fibers. The fibers are mixed with binders and a fire retardant. Finally, the materials are felted together into non-woven acoustic batts.
