What Are Steel Acoustic Doors?
Steel Acoustic Doors are specially designed doors that reduce sound transmission from one space to another. They combine robust steel construction, acoustic insulation, and precision sealing to block unwanted noise while offering enhanced fire resistance. These doors are ideal for environments that demand both safety and controlled acoustics.
Certified Fire Rated Steel Acoustic Doors
Ecotone’s fire-rated steel acoustic doors are rigorously tested to maintain structural stability and prevent fire spread during emergencies. These doors are available in 60-minute and 120-minute fire-resistant models, tested as per IS 3614 Part 2 and BS 476 Part 22. The certification confirms that the door remains intact and functional even under extreme fire conditions, providing essential time for evacuation and safety control.
Superior Acoustic Performance (STC Rating)
Designed to achieve reliable sound insulation, Ecotone Steel Acoustic Doors offer an STC rating of 36 TST. This performance has been tested according to international standards such as IS-9901 (Part III) – 1981, DIN 52210 Part IV – 1984, and ISO 140 (Part III) – 1995. These ratings ensure that the door effectively reduces airborne sound transmission, creating a controlled acoustic environment suitable for sensitive operations.
Technical Specifications & Construction
The door structure typically ranges from 55 mm to 65 mm in thickness, depending on the required fire rating and acoustic rating. Each door frame is constructed using MS pipe or ISMC sections, which enhance strength and stability. The shutter is fabricated from 18/16 SWG CRCA or GI sheet, and the inner cavity is filled with premium acoustic insulation material that restricts noise transfer. To prevent leakage of sound through gaps, Ecotone doors are fitted with Neoprene or EPDM rubber gaskets that create a tight and efficient seal between the frame and shutter.
Every door is equipped with heavy-duty hinges, strong handles, high-grade locking mechanisms, and other durable hardware components to ensure long-lasting and reliable operation. For external finishing, customers can choose from powder coating, PU paint, or spray paint, each offering excellent surface protection and an appealing appearance.
