Our quality standard applies not only at GEALAN itself, but also for our processors. This means that we give our customers specifications relating to window production and how to handle profiles, such as the best ways to drain, vent, brace, and store profiles. During regular quality checks, we review compliance with these quality specifications and award qualified window construction companies our GEALAN Qualitäts-Zertifikat (GEALAN Quality Certificate, GQZ) – because the premium nature of GEALAN products does not end at profile manufacture, but only when the high-quality window is fully installed!
