Performance
:
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.: 0.85
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 (HPVA)
Light Reflectance

Light reflectance average of 0.83 or greater. White only.: 86%
Sag/Humidity Resistance

Ceiling panels maintain humidity and sag resistance.: HumiGuard Plus
Insulation Value: R Factor-BTU: 2.9 BTU
R Factor-Watts: 0.445 m2 K/W
BioBlock

Ceilings with BioBlock performance resist the growth of mold and mildew.: Yes
Durability: Soil Resistance

Excellent resistance to dirt and/or grease for lasting value and performance.



Impact Resistance

Surface impact based on the Striking Ball Impact Test, modified ASTM D1037 procedure.



Scratch Resistance

Excellent resistance to surface scratching, scuffing or chipping as per Hess Rake Test.



Washability

Offers superior wash resistance without compromising panel finish integrity, using a washability tester as per ATSM D4828.
