When a controlled environment free of air-borne contaminants is paramount, every aspect of the design needs to contribute to maintaining cleanroom standards. Used in aerospace, microelectronics, food and beverage, pharmaceuticals, medical devices, and healthcare, cleanrooms require high-performing ceilings to create safe, productive spaces.

Rockfon’s ISO classified stone wool ceiling tiles meet low particle-emission requirements, feature high sound absorption, natural moisture resistance and a Class A Fire performance. When combined with Chicago Metallic® gasketed ceiling grid systems, they offer an ideal cleanroom solution that can span everything from a vast manufacturing facility to a small, specialized laboratory.


Featured ISO Class Products

Rockfon’s range of ISO classified products utilize the natural strengths of stone wool for cleanroom design.

Moisture Resistance – Because it is made using basalt rock, stone wool is naturally moisture resistant. It provides no sustenance to mold, mildew, bacteria and other microorganisms such as MRSA. This helps maintain cleanliness without the addition of antimicrobials. In a recent white paper, Perkins+Will explain how “healthy” antimicrobial products are doing more harm than good.1 Stone wool’s natural strengths make it an ideal material for spaces where air cleanliness is vital.

Low-Emitting - All of our stone wool acoustic ceiling solutions are GREENGUARD® Gold certified for low chemical emissions.

Acoustic – Featuring high Noise Reduction Coefficients (NRC), Rockfon’s acoustic ceiling tiles and panels offer excellent sound absorption. When used with our Optimized Acoustics™ approach, they help create comfortable, productive spaces.

Class A Fire Performance– Given stone wool’s volcanic origins, it can withstand extreme temperatures, naturally. Rockfon’s stone wool ceiling products have Class A Fire Performance, a Flame Spread Index of 0, and a maximum Smoke Developed Index of 5. This natural resistance means they are free from flame retardants that have been shown to cause diabetes, neurobehavioral and developmental disorders, cancer, reproductive health problems, and more.2
