Acoustic Insulation Cotton is a lightweight sound-absorbing material made from 100% polyester fiber, designed for projects that require practical noise control without adding significant structural load. Its three-dimensional fiber structure contains numerous micro-pores that absorb sound energy across a broad 100–4000 Hz frequency range, with an NRC of up to 0.95.
