Description Our fire-rated acoustic doors are engineered for maximum sound attenuation without compromising on fire safety. Featuring a multi-layered density core and a specialized triple-seal system, these doors effectively block high-frequency noise and low-frequency vibrations. Tested to international standards (UL and BS EN), they provide a critical barrier against fire and smoke while maintaining a peaceful environment. Available in various Sound Transmission Class (STC) ratings, these doors are the gold standard for recording studios, theaters, and high-end corporate boardrooms. Key Features High STC/Rw Ratings: Engineered to achieve Sound Transmission Class (STC) ratings from 35dB to 55dB, significantly reducing decibel transfer between rooms. Acoustic Perimeter Seals: Equipped with heavy-duty “automatic drop-down” bottom seals and triple-fin perimeter gaskets that create an airtight acoustic and smoke-proof chamber. Composite Core Infill: A specialized sandwich of high-density mineral wool, acoustic membranes, and damping sheets to absorb sound energy. Seamless Finish: Despite the complex internal tech, the exterior remains a sleek, professional steel finish available in any RAL color or wood-grain effect. Vibration Decoupling: The frame and hinges are designed to minimize the transmission of structure-borne vibrations.
