The common function of rockwool is to provide insulation in residential or commercial buildings. Rockwool can also protect pipelines, boats, mobile homes and domestic cooking equipment. Although most commonly known for providing insulation at home, people also use rockwool and slagwool as a growing horticultural medium.
Rock wool provides many advantages, including fireproof and soundproof. Because the fibers are non combustible and have an extreme melting point of over 2,150 degrees F, rockwool insulation acts as a fire barrier. Its flame-retardant characteristics can delay the spread of fire, which can add valuable minutes to escape during a fire. Rock also rejects water, anti-rot and fungi, including various types of bacterial growth. Because it refuses water, rockwool will not weaken or sag. The content of rockwool is solid, thus reducing airflow and transmission of sound waves.
