Given a benchmark thickness of 3.5 inches, a batt of Rockwool achieves an R-15 insulation value while fiberglass achieves an R-13 value, giving Rockwool about 15% better insulating ability over fiberglass at the same thickness. In addition to this, rockwool tends to settle once installed and a small air gap will form on top of it allowing sound, heat and cold to get through. Then, the molten glass is pushed through tiny holes to create thin filaments. Manufacturers use ordinary glass to produce fiberglass. The magma-looking liquid goes through a high-pressure air or steam jet. In terms of health and rock wool vs. fiberglass, neither are particularly harmful to human health.
