Ambience C400B Acoustical Ceiling Tiles, 1" or 2" thick, in a Black cloth facing offer high sound absorbency combined with a pound per square foot mass loaded vinyl (MLV) barrier. The result is a high sound transmission class (STC) rating and noise reduction coefficient (NRC). Ambience C400B Ceiling Tiles rely on a high-density fiberglass core to produce excellent NRC results.
Ambience C400B Ceiling Tiles are Class A fire-rated, designed to fit in standard 2'x2' or 2'x4' lay-in ceiling tile grid.Tiles are cut to 23-3/4" x 23-3/4" or 23-3/4" x 47-3/4".
