Acoustic fire doors are critical safety and functional components in modern architecture, especially for high-rise buildings, public spaces, and facilities with special purposes (such as hospitals, laboratories, and recording studios).
Core Definition and Standards
Acoustic Fire Door:
Fire Door:
In the event of a fire, it can meet the requirements for fire resistance integrity, thermal insulation, and even smoke resistance for a specified period (e.g., 0.5 hours, 1.0 hours, 1.5 hours). Primarily governed by fire codes.
Acoustic Door:
Effectively blocks the transmission of airborne sound, reducing the passage of sound from one space to another. Primarily defined by acoustic performance metrics.
Acoustic Fire Door:
Combines both functions. It must simultaneously pass certification tests by national authoritative bodies for both fire resistance performance and airborne sound insulation performance.
Key Performance Standards:
Fire Resistance: Chinese standards commonly use Class A (≥1.5h), Class B (≥1.0h), Class C (≥0.5h). International standards often use EI60, EI90, EI120 (E for integrity, I for insulation, number for minutes).
Sound Insulation: The Chinese standard uses Weighted Sound Reduction Index (Rw), measured in decibels (dB). Common ratings for acoustic fire doors include Rw 35 dB, 40 dB, 45 dB, etc. A higher value indicates better sound insulation. Internationally, STC (Sound Transmission Class) ratings are also commonly used.
Primary Applications
Public Buildings: Hospitals (operating rooms, ICUs, audiometric booths), theaters, concert halls, cinemas, conference rooms.
Research & Education: Laboratories, recording studios, broadcasting rooms, classrooms, libraries.
Commercial & Residential: High-end hotel rooms, KTV rooms, premium office building meeting rooms, high-end residential entry doors, and home theaters.
Industrial Facilities: Factory control rooms, equipment rooms (e.g., generator rooms, pump rooms).
An acoustic fire door is a systematic engineering product, combining materials science, acoustic design, mechanical structure, and precision installation. When selecting one, it should be considered as a "performance system" rather than a simple "door product." Ensuring every step—from design and procurement to installation and inspection—meets professional standards is essential to truly realize its value in providing safety and tranquility.
