With the introduction of new Calla Ceilings, Armstrong now offers the smooth look of drywall in a ceiling panel that also provides excellent acoustical performance and plenum accessibility.
The new addition to the Armstrong line has a cool white finish and is the smoothest-looking mineral fiber ceiling panel available in the market. With its high NRC (Noise Reduction Coefficient) of 0.85 and CAC (Ceiling Attenuation Class) of 28, Calla offers a combination of sound absorption and sound blocking capabilities in a single product, ensuring a balanced acoustical design in both open or closed plan spaces without the need to specify two separate ceilings.
