Fire Cum Acoustic Doors
STRONG DOORS. SAFE SPACES.
Engineered soundproof fire-rated doors delivering certified sound attenuation up to 42 dB and up to 120-minute fire containment. Tested to ASTM-E90 & IS 3614:2021 standards.
Fire Cum Acoustic Doors
Fire cum acoustic doors are specially designed to provide both high fire resistance and sound insulation, ensuring life safety and noise control in critical environments. Manufactured using high-quality steel or engineered hardwood with specialized acoustic and fire-resistant core infill, these doors offer superior protection while maintaining a quiet and secure indoor environment.
Ideal for commercial, industrial, healthcare, hospitality, and institutional spaces, they comply with certified fire integrity and laboratory-tested acoustic decibel reduction standards.
Fire Cum Acoustic Door Performance & Features
Engineered with advanced acoustic core infill and continuous perimeter compression gaskets to provide unmatched noise dampening and thermal containment.
Fire cum acoustic doors eliminate the compromise between life safety and acoustic quietude, ensuring optimal performance for modern sensitive architectural spaces.
Key Features of Acoustic Fire Rated Doors
Built to rigorous international testing protocols for high acoustic decibel isolation and high fire ratings.
Fire Resistance Ratings
Our fire cum acoustic doors are available in multiple fire resistance ratings including 60 minutes, 90 minutes, and 120 minutes, ensuring reliable protection during fire emergencies.
Dual Performance Construction
Engineered using high-quality steel or wooden structures, these doors provide both fire protection and superior acoustic insulation in a single certified solution.
Acoustic Fire-Resistant Core
The door leaf is filled with high-density mineral wool, viscoelastic damping rubber sheets, and acoustic core materials that ensure excellent sound insulation while maintaining fire resistance.
Smoke & Heat Sealing
Advanced perimeter intumescent gaskets and mechanical drop seals prevent the passage of smoke, heat, and airborne sound, maintaining a controlled indoor environment.

Advantages Of Fire Cum Acoustic Doors
Fire cum acoustic doors provide an ideal combination of safety, acoustic decibel insulation, and heavy-duty structural durability. Designed to contain fire and toxic smoke while eliminating sound transmission, these doors are widely specified across broadcast studios, hospitals, commercial complexes, and hospitality venues.
Prevents Spread Of Fire, Smoke & Sound
These doors act as a high-integrity barrier that restricts the spread of fire, smoke, and noise between different zones, ensuring superior compartmentalization and acoustic privacy.
Ensures Safe Evacuation Time
Designed to withstand catastrophic fire exposure for up to 120 minutes, these doors grant building occupants safe egress through corridors and protected stairwells.
Enhances Safety & Acoustic Comfort
They satisfy all statutory fire life-safety regulations while significantly attenuating disruptive noise levels (up to 42 dB), vastly improving occupant comfort and focus.
Dual Performance Efficiency
Combines certified fire resistance and specialized acoustic soundproofing into a single engineered door assembly, eliminating the complexity and cost of separate systems.
Ideal For Sensitive Environments
The premier choice for recording studios, healthcare consultation rooms, cinema multiplexes, educational auditoriums, and hotel conference ballrooms.
Durable & Long-Lasting Performance
Fabricated from precision-formed steel and premium kiln-seasoned hardwoods, these assemblies endure heavy daily duty cycles with minimal maintenance.
