We introduce ourselves

The RAL quality mark is awarded for many different products and services. All products and services bearing this quality mark are manufactured according to precisely defined quality criteria and to a consistently high standard. More information about the RAL quality mark can be found here.

The members of the Gütegemeinschaft Flachglas e. V. form a strong community. As a recognized platform for all questions of product quality and usability, we set quality standards. We take care of all quality issues relating to insulating glass and its preliminary products and also create the conditions for ESG to continue to be used in buildings without restriction. Our quality committees are elected by the general meeting and stand for neutral external monitoring by the institutes. Together with the competently staffed office, they monitor the requirements for the use of quality marks. In addition, we cooperate with other quality associations around the window – for a continuous quality chain!
