Acoustics
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.

Light Reflectance

A high light reflective ceiling – LR 0.83 or greater, per ASTM E1477-98 as referred to in ASTM E1264-98 – makes lighting systems, especially indirect lighting, more effective while further reducing energy costs and consumption. LR values apply to White panels only.

88%
Anti-Microbial
Mold/Mildew Resistance

Ceiling panels with BIOBLOCK performance resist the growth of mold and mildew on the panel surface.
Ceiling panels with BIOBLOCK Plus performance resist the growth of odor and stain-producing bacteria as well as mold and mildew on the ceiling panel surface.

Inherent
Humidity
Sag/Humidity Resistance

Ceiling panels maintain humidity and sag resistance.

HUMIGUARD Plus
Durability
Soil Resistance

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

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.
