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 Room™s, 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.
