Product Description

Our PrivacyShield® High CAC Foam Soundproofing Ceiling Tile, (formerly AlphaSorb® High CAC Ceiling Tile) is a high-performance ceiling tile that is perfect in a space that needs quality sound that also needs speech privacy for confidential conversations or is adjacent to rooms that need to be quiet. Unlike most acoustic ceiling products, our PrivacyShield® High CAC Foam Soundproofing Ceiling Tile provides both maximum sound absorption and superior noise blocking strength.

The absorptive properties of the acoustic foam in the ceiling tile reduces reverberation and sound reflections within the space and offers a Noise Reduction Coefficient (NRC) of 0.85. The fire-rated gypsum backer in the product provides a Ceiling Attenuation Class (CAC) of 45 to aid in blocking sound. The soundproofing strength of the product prevents sound transmission from traveling over demising walls, through the ceiling cavity, and into neighboring rooms. All together this powerful dual function ceiling tile improves comfort and reduces noise for a range of applications using drop tile grid systems.
