USG Research conducted the tests with a. variety of partition designs. The results: Thermaï¬ ber mineral wool. insulation in the 2.5 to 3.0 lbs/cu.ft. density range proved the best. overall acoustical performance. Densities above the 3 lbs/cu.ft. provided improved sound attenuation at high frequencies, but the. low-frequency performance starts to suffer at higher densities.
Asbestos is a mineral fiber that occurs in rock and soil. Learn about vermiculite and asbestos-contaminated vermiculite insulation. Because of its fiber strength and heat resistance asbestos has been used in a variety of building construction materials for insulation and as a fire retardant.
