Firewater barriers HD/GDZ and HD/PH have been tested by TÜV Rheinland

Thus, both firewater retention systems HD/GDZ and HD/PH meet the requirements of the VDS guideline 2564-1 and receive the TÜV “Bauart geprüft” quality seal. They therefore meet the relevant safety technical requirements for such systems.
