Kairatin is an acoustic design panel with a dual function. It is made of Keratine, also known as sheep wool. Keratine is a renewable, ecological and secondary natural resource. It has the benefit that it eliminates unwanted gases by means of a chemical reaction. This effect will remain active for decades. Furthermore, it acts as a flame-spreading barrier because it has a nitrogen level of 16%, a relative moist level of 14 – 18% and a combustion temperature of 600 °C. Furthermore, Keratine is an endothermal material, meaning it requires more energy to let it burn, than it releases during burning. It has an oxygen index level of 25.2% meaning that for combustion of keratine, the level of oxygen should be at least 25%, while plain air consists of only 21% oxygen. The material purifies air and at the same time offers high acoustic absorption. Toxic gases such as formaldehyde, sulphur dioxide and ammonia are impeded by the panels, while the sound absorption coefficient has a NRC value of 0.90.
