Why stone wool insulation

Sound Absorbent for acoustic comfort: The non-directional structure of ROCKWOOL stone wool insulation is denser than traditional insulation products which helps to absorb acoustic waves and can reduce the intensity and propagation of noise.Stone wool also effectively reduces airflow and sound transmission, while providing higher airflow resistivity for improved sound attenuation.
