Wooden Fire Doors, Fire Rated 60/90/120 Min | Packsound
Wooden Fire Doors are timber based door assemblies engineered with a fire resistant core, intumescent seals and fire rated hardware to stop flames and smoke from moving between rooms for a fixed period of time, commonly 30, 60, 90 or 120 minutes. They look like a standard wooden door but are tested and certified under IS 3614 to hold a fire rated door opening during a real fire, giving occupants extra time to evacuate and giving fire fighters extra time to respond.
SonicGuard™ Wooden Fire Doors: Fire-Rated Safety with Acoustic Insulation
SonicGuard™ Wooden Fire Doors are engineered to deliver superior fire resistance, acoustic insulation and architectural elegance in one integrated solution. Designed for modern commercial and residential environments, these fire-rated wooden doors provide critical protection against fire spread while also minimizing sound transmission between spaces. With a combination of robust core construction, precision sealing systems and premium wood finishes, SonicGuard™ doors ensure safety, privacy and aesthetic excellence.
In today’s buildings, compliance with fire safety standards is non-negotiable. At the same time, architects and designers demand materials that enhance interior aesthetics. SonicGuard™ Wooden Fire Doors meet both requirements by offering certified fire resistance along with elegant wood veneer finishes. These doors are ideal for offices, hotels, hospitals, educational institutions and high-end residential projects where safety and design must coexist.
Built using advanced fire-resistant cores and intumescent sealing technology, these doors automatically respond to high temperatures by sealing gaps and preventing the spread of flames and smoke. In addition, their dense core structure provides excellent acoustic insulation, making them a dual-purpose solution for fire safety and noise control.

Acoustic Performance
SonicGuard™ Wooden Fire Doors provide effective sound insulation alongside fire protection. The dense, multi-layered core acts as a barrier to sound transmission, reducing noise transfer between spaces. With STC ratings ranging from 30 to 45+, these doors are capable of blocking common noise such as speech, office activity and moderate ambient sound.
Also Check: Wooden Acoustic Doors. The sealing system plays a critical role in acoustic performance. By eliminating gaps around the door frame, it prevents sound leakage and enhances overall insulation. When combined with acoustic wall systems, these doors contribute to a fully controlled acoustic environment.
