Many people believe that fire-resistant glass doors and windows simply consist of qualified fire-resistant glass paired with fire-resistant hardware, and once assembled, they meet all required standards for delivery.As a leading manufacturer specializing in the research, development, and production of fire protection systems, we must emphasize unequivocally: A truly compliant fire-resistant glass door or window that withstands fire testing constitutes a complete fire protection system, not merely a simple combination of components such as glass, profiles, hardware, and seals. Fire-resistant glass certified separately or hardware parts submitted for individual inspection may not pass comprehensive fire resistance testing when assembled together, let alone obtain full compliance certification—a key reason why numerous projects face acceptance challenges.
