Acoustics

Acoustical options available.
 
Sound Absorption (NRC)

A measure for rating the overall sound absorption of a material when used in an enclosed architectural space where sound is reflected at many angles of incidence. A ceiling system with an NRC < 0.50 is low performance, an NRC > 0.70 is high performance.
0.90
Articulation Class (AC)

Product has AC (Articulation Class) 170 or greater.
190
Fire  
  Fire Performance Class A (UL)
Light Reflectance

Light reflectance average of 0.83 or greater. White only.
88%
Sag/Humidity Resistance

Ceiling panels maintain humidity and sag resistance.
