Health and stone wool
ROCKWOOL insulation is made of stone wool, which is a fibrous material. Depending on how the material is cut, some dust may occur. Nevertheless, stone wool is a completely non-hazardous material to work with.
No risk of lung diseases
This fact is supported by the decision of the World Health Organisation’s International Agency for Research on Cancer (IARC) to exempt stone wool from its list of “possibly cancer causing agents”. The conclusion was based on the fact that epidemiological studies provide no evidence of an increased risk of lung cancer from occupational exposure to stone wool fibres, and that there has been no excess of tumours in long-term inhalation studies in animal experiments. Similar there was no increased risk of lung fibrosis.
No risk form volatile organic compounds
Comprehensive full-scale investigations of emissions from stone wool insulation products at the Fraunhofer Institute in Braunschweig show that they are a negligible source of formaldehyde in the indoor environment and therefore of no concern for the inhabitants of houses insulated with stone wool products.
Limiting skin discomfort
Being made basically from stone, there are naturally coarse fibers, which may cause skin discomfort for some people when getting in contact with the products in the installation phase. However, the discomfort is simple mechanical reactions to the coarse fibers and it will not leave damage to the skin.
The discomfort generally declines within a short time after the end of exposure. Also, professionals, who are handling ROCKWOOL stone wool products continually will generally experience that skin discomfort diminishes over time.
How to best work with stone wool
Cutting stone wool with a sharp cutting tool such as a sharp knife, it will usually not create any dust in significant levels (or in very low levels). However, when cutting tools with teeth are used, it can generate dust as a result of abrading of the individual fibres.
Generally when working with stone wool,, some precautions can be taken to protect skin and minimize possible discomfort, such as wearing proper protection, glasses and cleaning thoroughly. Read and follow the simple steps in this installation advice, to stay completely safe when working with our products.
