In accordance with the purpose of the association – which is to ensure quality assurance – the Gütegemeinschaft Kunststoff-Fensterprofilsysteme arranges a large number of meetings of technical working groups involving its ordinary members, system designers as well as sponsoring and supporting members from the seal raw materials, seal manufacturing, bonding manufacturing and film manufacturing industries. Networking with the commissioned test institutes is also necessary, fruitful and a matter of course in this context.

With system designers understanding themselves to be responsible for the plastic window profile system, the association maintains close and regular technical exchanges with the sister RAL quality associations for windows and front doors, locks and hardware and insulating glass units as well as member plants of these quality associations.

At European level, the quality association and its ordinary members are the driving force behind the establishment and life of the EPPA, the European PVC Window Profile and Related Building Products Association.

The collaboration with RAL Deutsches Institut für Gütesicherung und Kennzeichnung e.V. in St. Augustin, the “licensor” of the RAL quality mark, should be mentioned at this point purely for the sake of completeness.
