Washable Antimicrobial Mineral Board Panel
The Washable Antimicrobial Mineral Board Panel delivers a hygienic, easy-to-clean ceiling and wall surface engineered for spaces where sanitation is non-negotiable. It extends the performance of our specialized mineral board family, aligning with the strict protocols met by the Cleanroom Antimicrobial Mineral Ceiling Board and the Pharmaceutical Cleanroom Mineral Board. For areas exposed to humidity or frequent washdowns, the panel provides attributes similar to our Moisture Resistant Antimicrobial Mineral Ceiling Board, while sharing the passive fire resistance seen in the Fire Resistant Antimicrobial Mineral Ceiling Board. The board integrates a scrubbable, non-porous finish with built-in antimicrobial protection, maintaining surface integrity after repeated cleaning. It inhibits the growth of bacteria, mold, and mildew, making it a reliable choice for hospitals, laboratories, food processing plants, and clean manufacturing suites. The smooth, low-particulate emission surface simplifies maintenance while contributing to indoor air quality.
The Washable Antimicrobial Mineral Board Panel combines acoustic control, fire safety, and durable hygiene in a single mineral-based panel. Its core is reinforced with a permanent silver-ion antimicrobial agent that is evenly distributed throughout the board, delivering protection that does not wash off or wear away. The facing is formulated to withstand hundreds of scrub cycles using common healthcare-grade disinfectants without discoloration, peeling, or loss of antimicrobial function. This robust design supports strict cleaning regimens without compromising ceiling performance over time.
- Scrub resistance rated to ASTM D4828, surpassing 1,000 cycles with no visible damage
- Antimicrobial efficacy verified per JIS Z 2801 and ASTM G21, reducing bacterial colonies by >99.9%
- Fungal resistance per ASTM G21, ideal for moisture-prone clean areas
- Fire classification Euroclass A2-s1,d0 and ASTM E84 Class A, contributing to passive fire protection
- Sound absorption with NRC values between 0.65 and 0.75, minimizing reverberation in hard-surface rooms
- High light reflectance (LR-85+) to enhance illumination and reduce lighting energy consumption
- Dimensional stability in relative humidity up to 95%, preventing sag or warping
- Low VOC emissions, meeting CA CDPH/EHLB Standard Method v1.2 for indoor air quality

The panel installs in standard 24 mm or 15 mm grid systems and can be cut on-site with standard tools without fraying edges, maintaining a clean aesthetic. Its high-performance facing sheds dust and resists stains, reducing the need for replacement in demanding environments. By combining washability, antimicrobial action, and fire-rated mineral board structure, the Washable Antimicrobial Mineral Board Panel supports facility compliance with cGMP, HACCP, and healthcare guidelines without sacrificing ceiling architecture or acoustic comfort.
