Acoustic Doors

Cronax Acoustic Doors are designed to deliver superior sound insulation for environments where noise control and privacy are critical. Engineered with high-performance sound-absorbing cores such as mineral wool, rockwool, or honeycomb infills, these doors effectively reduce sound transmission while maintaining structural durability and fire safety. Built with robust steel or timber-reinforced panels, our acoustic doors feature precision sealing systems around the frame and threshold to eliminate sound leakage. They are available in single or double-leaf configurations, with optional vision panels, fire rating, and full automation for specialized applications.

Widely used in auditoriums, studios, conference halls, hospitals, educational institutions, research labs, and industrial facilities, Cronax Acoustic Doors ensure compliance with international acoustic standards, offering STC ratings tailored to specific requirements. With their aesthetic design, noise-reducing performance, and long service life, provide the perfect balance between functionality, safety, and comfort in noise-sensitive environments.
