Just because a curtain is "thick" doesn't make it acoustic. For a professional solution, the fabric's NRC (Noise Reduction Coefficient) rating must be considered. Micronized pore structures and multi-layered heavy barrier linings trap sound waves within the fabric and convert them into heat. Our laboratory-tested fabrics offer performance between 0.70 and 1.00 NRC, completely transforming the sound characteristics of the space.
