Acoustic Plus Dual Bloc 35mm Ceiling Tiles

Acoustic Plus Dual Bloc is a 35mm composite acoustical suspended ceiling tile. The combination of sound absorbing glass fibre laminated to a plasterboard attenuator backer is engineered to provide the dual benefit of sound absorption at NRC 0.70 and a high level of attenuation at CAC 42 for cost effective control of both reverberation and transmitted noise from adjacent rooms.

Acoustic Plus Dual Bloc will also provide attenuation of rain noise under metal roofing and muffle noise caused by ventilation ducting.
