Armstrong Cortega Ceiling Tile 24×24

These mineral-fiber panels measure 24 inches by 24 inches with a 5/8-inch thickness and an angled tegular edge. They suit commercial or residential drop-ceiling installations that require a Noise Reduction Coefficient of 0.55 and a Ceiling Attenuation Class of 35. The white, non-directional finish delivers a light reflectance of 0.82. A pack contains twelve tiles covering 48 square feet.

Grid and environment checklist

Verify that the existing suspension grid uses a 15/16-inch profile to match the tegular edge detail. Confirm the installation area stays within the 32 to 120 degrees Fahrenheit operating range. Ensure the structure can support the 49.25-pound pack weight during handling and mounting. The tiles carry Fire Guard and Humiguard Plus features for fire resistance and humidity protection.

Upgrade from standard mineral-fiber panels

These tiles replace basic ceiling panels that lack the 0.55 NRC rating or the Class 35 attenuation needed for better speech privacy. The 41 percent recycled content and ASTM E1264 compliance suit projects targeting greener building standards. The jump is worth it when acoustic control, fire resistance and high light reflectance are specified together.
