The Armstrong family of Ultima Health Zone ceilings now offers enhanced sound absorption and sound-blocking performance to address the growing concern over noise control and speech privacy in health-care settings. Armstrong has increased the Ceiling Attenuation Class of the ceiling panels to 38 and Noise Reduction Coefficient to 0.70. Ultima Health Zone ceilings provide a water-repellant, washable and scrubbable surface that is safe for use with disinfectants. The panels, which can be used in Clean Room Assemblies, are formulated to inhibit the growth of mold and mildew and contain an agent to resist odor and stain-causing bacterial growth.
