Together, the members of the Gütegemeinschaft Flachglas e. V. are a strong community. As the recognized platform for all questions regarding product quality and usability we set quality standards. We take care of all quality issues involving insulating glass and its components and, furthermore, lay the foundationos for ensuring that TSG in buildings can continue to be used without restrictions. Our Quality Committees are elected by the General Meeting and represent the neutral external monitoring by the institutes. Together with the competently staffed head office they monitor the requirements for carrying the Quality Mark. Additionally, we work with other RAL Quality Associations involved with windows - for an integrated quality chain!
