Chrysotile belongs to the asbestos group and is also known as white asbestos. It is a fibrous layered silicate from the serpentine group.
Chrysotile was in the past mainly used for heat-resistant materials (e.g. heat-resistant clothing, thermal insulation, gaskets, ropes) and to increase the material stability in fibre cement panels (facades, roofs). However, other areas (e.g. older bituminous sealing compounds and sealants in road and bridge construction, mortars, plasters, fillers, etc.) may also contain chrysotile asbestos, often in combination with PAH.
For this reason, it is advisable to carry out an expert examination of the building fabric in the case of modernisation and demolition measures as well as the upgrading of air conditioning and fire protection building equipment (heating systems, fire dampers, etc.), especially in older buildings from the 1960s to 1980s.
