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.
NIOSH recommended exposure level is 3. fibers/cc. This material is slag wool. Other generic terms that are used or have been used to classify this material. include mineral wool, man made mineral fiber (MMMF), and man made vitreous fiber (MMVF). A more recent generic.
