SoundAttenuation/AcousticCore–Non-Rated

Sound Attenuation / Acoustic Core – Non-Rated

  • Engineered to reduce sound transmission between spaces in healthcare, educational and office environments

  • Dense, uniform core provides consistent acoustic performance

  • Offers durability for moderate- to high-traffic interior applications

Sound attenuation / acoustic cores are designed for environments where sound control and privacy are important. The specialized core material absorbs and dampens sound, while the construction type determines the door’s durability and suitability for high-traffic or sensitive interior spaces.

The table below outlines the key characteristics of acoustic core to help guide specification decisions.
