Armstrong Clean Room™ VL ceiling tiles absorb sound and are washable, scrubbable, and soil-resistant. They also meet all USDA/FSIS and controlled environment guidelines. The Clean Room™ VL Bundle includes tiles and all the components of the 15/16" Co-Extruded Clean Room™ suspension system. This custom system is designed specifically for clean rooms, food processing areas, and data centers where air systems need to be controlled and as little air as possible can get into the space through the ceiling.
