General
Artificial mineral fibres are mostly used for thermal and acoustic insulation as well as fire protection in buildings. Since the rock wool fibres are harmful to health, there are strict rules for the removal and disposal thereof similar to those relating to asbestos. This is to exclude possible hazards for operatives, users and for the environment.
At the basis of the technical and organisational measures regarding removal and disposal is the TRGS 521 (demolition, removal and maintenance works concerning old mineral wool). We possess this relevant certification, therefore we are a specialist company for the removal of artificial mineral fibres.
What are artificial mineral fibres?
The term "mineral wool" comprises insulating material such as glass and rock wool colloquially also known as Kamelit or Kamelit wool.
During the production of same a melt of glass or stone is spinned through a circular sieve and is thus structured into a non-woven fabric.
Another possibility is to lead the melt over a rapidly rotating roller. Once this process is finished, the material will be resistant to mould, rottening and vermin no matter what method of production.
Application of mineral wool
Mineral wool is used as insulation material in the walls and roofs of lots of houses. There it is particularly used for thermal insulation, while stone wool also serves as acoustic insulation. The benefit of mineral wool is its high fire resistance and its insulating functions with an impact inside and outside.
As to their application a distinction has to be made between rock wool and glass wool, while advantages and drawbacks are of mutual nature. Glass wool has a higher insulation factor and is easier to compress whereas rock wool has a higher acoustic insulation factor and is convincing due to its thermal stability.

Risks of mineral wool
The dangers arising from mineral wool are first of all superficial irritations of the skin and the mucous membranes. In some people the flying fibres trigger allergic reactions. Dust from rock wool as well as mineral wool is classified as potentially carcinogenic which, however, could only be proved in animal experiments. Hazards from mineral wool usually occur during the processing of same.
When working with mineral wool, meticulous care should be taken to ensure that protective clothing is worn. Specific attention must be given to the protection of the lungs against dust since the fine fibres might penetrate the lungs and thus have a carcinogenic effect.
Removal of contaminated material and disposal thereof
The removal and disposal of material contaminated with mineral wool should be entrusted to trained specialists such as Senft GmbH since incautious behaviour may result in inflammations of the eyes and the respiratory passages.
