Rock wool is an inorganic fiber that is environmentally friendly, safe, green, and harmless to the human body.
As an inorganic material, rock wool offers excellent thermal insulation, heat preservation, sound absorption, fire resistance, and air permeability. With these comprehensive properties, rock wool is an unmatched building insulation material. It’s extremely low thermal conductivity gives rock wool products outstanding thermal insulation performance.
