On a holistic understanding of quality, quality assurance according to RAL GZ-716 covers the entire PVC window system, from the raw material to the end product. In addition to the profile, it encompasses all components that are installed in the PVC window, such as reinforcements, connectors and cover profiles. The system also includes components such as gaskets and decorative films. That means the entire value chain is subject to seamless quality assurance. Thus interdependencies are also recorded and assured, the aim being for the processor to ultimately have a high-quality window system that is fit for use.
Four quality associations – one common product
There are four quality associations involved in a finished RAL PVC window. As the Gütegemeinschaft Kunststoff-Fensterprofilsysteme, for instance, it is our task to verify the fundamental suitability of the window system, including its components. For more about the tests, please refer to the section on quality-defining features.
The quality of the insulating glass used in the finished window is monitored by the Gütegemeinschaft Flachglas/Troisdorf, that of the fittings by the Gütegemeinschaft Schlösser und Beschläge/Velbert. Quality assurance of the PVC window as an end product together with assembly is the responsibility of the Gütegemeinschaft Fenster, Fassaden und Haustüren/Franktfurt. If you want to be absolutely sure of quality, then, look out for windows and window companies carrying the RAL quality mark.
