Difference	ROCKWOOL Insulation	Asbestos
Raw Materials	Basalt, Dolomite	Silicate minerals
Origin	Produced by melting rock and spinning it into fibers, mimicking the natural volcanic eruption process	Formed by the accumulation of silicate minerals
Properties	Melting point of 1000°C, excellent heat resistance, non-flammable, does not spread fire, and produces no smoke	Heat resistance between 700-1000°C, durable and strong
Fiber Characteristics	Diameter approximately 4-6 microns, too large to be inhaled into the lungs	Diameter less than 1 micron, small enough to be inhaled into the lungs
Fiber Breakage	Breaks with rounded edges, like chalk	Breaks into sharp fragments, which can become airborne
Usage	Used as fire, heat, and sound insulation, and for sound absorption	Used in various industrial products like brake pads, cement pipes, and roof tiles
Health Impact	Does not cause cancer in humans	Causes cancer in humans
International Agency for Research on Cancer (IARC)	Group 3: Products not classified as carcinogenic to humans, including stone wool insulation, electromagnetic fields, and certain types of tea	Group 1: Products classified as carcinogenic to humans, including tobacco smoke, alcoholic beverages, and asbestos
