Fire Class

Light Reflectance

0.850

Light reflection expressed in % is measured in accordance with ASTM E1477.

Humidity And Sag Resistance

Up to 100% RH

Stone wool ceiling tiles are inherently resistant and are tested to ASTM C367 (Standard Test Methods for Strength Properties of Prefabricated Architectural Acoustical Tile or Lay-In Ceiling Panels) and won’t sag or warp even in 100% relative humidity.

Cleaning

Vacuum, Damp cloth, Chemical resistance: resistant to diluted solutions of ammonia, chlorine and hydrogen peroxide

Vacuum
Damp cloth
Rockfon Sonar® tiles are able to be washed through 100 cycles of the standard washability tester and cleaner prescribed in ASTM D4828.
Rockfon Sonar® panels can withstand up to 200 scrub cycles using the prescribed scrubber and force per ASTM D2486.
Rockfon Sonar® can be safely treated with a number of cleaning solutions and are resistant to diluted solutions of ammonia, chlorine, quaternary ammonium and hydrogen peroxide as described in ASTM D1308.

Hygiene

Stone wool provides no sustenance to microorganisms

Rockfon Sonar® stone wool substrate and tile surfaces are inherently resistant to mold and mildew and are tested to ASTM D3273 (Standard Test Method for Resistance to Growth of Mold on the Surface of Interior Coatings) and ASTM C1338 (Standard Test Method for Determining Fungi Growth Resistance of Insulation Materials and Facings).
