Its insulation properties are due to natural entrapped air and therefore it does not emit noxious gases or blowing agents like HCFC, pentane, CO2. More acoustic protection: Rockwool stone wool has a natural open cell structure making it ideal for absorbing and regulating noise. More sustainability: Rockwool stone wool is one of the most environmentally robust insulation materials in the world. In its lifetime a typical ROCKWOOL insulation product saves more than 100 times the energy invested in its manufacture, transport and disposal. Its properties remain on a high level during the whole life cycle. This long term performance is a key environmental characteristic, plus there is no need to upgrade the insulation after a period of time. rockwool stone wool is based on a renewable and plentiful natural resource and is not considered as harmful to humans.
