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
Sound Blocking (CAC)

A measure for rating the performance of a ceiling system as a barrier to airborne sound transmission through a common plenum between adjacent closed spaces. A ceiling system with a CAC < 25 is considered low performance, whereas one with CAC of 35 or higher is high performance.
35
Articulation Class (AC)

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

Light reflectance average of 0.83 or greater. White only.
85%
Sag/Humidity Resistance

Ceiling panels maintain humidity and sag resistance.
HumiGuard Plus
Insulation Value R Factor-BTU: 5.83 BTU
