Gütegemeinschaft Mineralwolle e. V.

25 years of RAL quality control for mineralwool


Rackwitz, May 2024 - In June 2024, the Gütegemeinschaft Mineralwolle e. V. celebrates the 25th anniversary of the first quality mark for mineral wool. In the field of insulation materials, this label has stood since 1999 for the safe processing of mineral wool products made from sustainable raw materials such as glass or stone.

The history of the Gütegemeinschaft Mineralwolle is a success story. Almost one hundred percent of all mineral wool offered in Germany is awarded the quality mark, which was graphically updated in 2013. In addition, production facilities from abroad are increasingly following the GGM regulations in order to be able to offer a tested quality product in Germany. 

The continuous neutral inspection of the plants affiliated with the GGM ensures that mineral wool is harmless to health. This is done by wet chemical analysis of the respective fibres at accredited analysis institutes. A list of these institutes is available from GGM.
