Maintaining a sterile and controlled environment demands more than just regular cleaning—it requires a ceiling system that actively combats contamination. Our Cleanroom Antimicrobial Mineral Ceiling Board delivers that defense, integrating proven antimicrobial protection into a high-performance mineral fiber panel. For spaces where humidity is a constant challenge, the Moisture Resistant Antimicrobial Mineral Ceiling Board offers exceptional sag resistance and microbial defense without compromising acoustic comfort. When fire safety cannot be compromised, the Fire Resistant Antimicrobial Mineral Ceiling Board combines Class A surface burning characteristics with the same hygienic performance. In facilities that rely on rigorous daily washdowns, the Washable Antimicrobial Mineral Board Panel stands up to repeated cleaning while preserving its structural integrity and antimicrobial properties. And for the most demanding pharmaceutical production spaces, the Pharmaceutical Cleanroom Mineral Board meets GMP requirements with validated microbial resistance and particle emission control. Each panel in this family is engineered to perform under strict cleanroom classifications, ensuring long-term durability and regulatory compliance.
The Cleanroom Antimicrobial Mineral Ceiling Board uses an advanced silver-ion antimicrobial agent uniformly dispersed throughout the mineral wool core and surface coating. This permanent additive works continuously to inhibit the growth of bacteria, mold, and mildew on the panel surface, maintaining a cleaner ceiling plane even between scheduled cleaning cycles. The board features a smooth, non-porous facing that resists dust accumulation and allows for easy wiping with common disinfectants. Its high-density mineral fiber composition provides excellent sound absorption and sound attenuation, creating a quieter workspace without sacrificing sterility. Edge details include square and tegular options, making the board compatible with standard 15/16" and 9/16" suspension systems. Additionally, the panel maintains dimensional stability under variable humidity conditions, reducing the risk of warping or visible joints over time. Whether installed in a hospital operating room, a semiconductor fabrication facility, or a food processing plant, the Cleanroom Antimicrobial Mineral Ceiling Board contributes directly to a controlled environment where hygiene and performance intersect.
Key Performance Features
- Integrated silver-ion antimicrobial technology suppresses microbial growth on all exposed surfaces
- High-density mineral wool core delivers superior sound absorption (NRC 0.60–0.70) and sound blocking (CAC 35–39)
- Washable, soil-resistant acrylic or PVC surface withstands frequent cleaning with diluted quaternary ammonium, hydrogen peroxide, or alcohol-based disinfectants
- Excellent moisture resistance maintains panel flatness up to 95% relative humidity
- Complies with Class A fire performance per ASTM E84, with flame spread index ≤ 25 and smoke developed index ≤ 50
- Low particle emission and outgassing qualify the panel for ISO Class 5 (Class 100) and above cleanrooms
- Square or tegular edge profiles ensure a tight seal against the grid, minimizing air bypass and particle accumulation
- Lightweight design simplifies handling while meeting seismic restraint requirements when properly installed
- Dimensionally stable under temperature fluctuations, reducing touch-up maintenance needs
- Available in multiple standard sizes and metric dimensions for retrofit or new construction projects
