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.

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.

Sag/Humidity Resistance

Ceiling panels maintain humidity and sag resistance.

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.


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