Armstrong Ultima Ceiling Medallion 24x24 3/4

This Armstrong Ultima ceiling medallion measures 24 inches by 24 inches with a 3/4-inch thickness. It is made from mineral fiber and comes in a white finish. The beveled tegular edge fits a 15/16-inch grid system. Each pack contains twelve tiles covering 48 square feet.

Suited for healthcare offices and classrooms

The tile offers a noise reduction coefficient of .8 and a ceiling attenuation class of 35 for sound control. Light reflectance of .9 brightens rooms while 77 percent recycled content supports sustainability goals. It resists bacteria, mold, mildew, sag, scratches, soil and impact. Buyers needing a different grid size or a non-mineral-fiber material should look elsewhere.

Handles standard commercial ceilings

The product operates in temperatures from 32 to 120 degrees Fahrenheit. Fine texture and beveled edges provide a clean appearance across the 48-square-foot coverage. Weight of 49.8 pounds per pack is a factor for handling and installation planning. It is not designed for exterior exposure or high-humidity environments beyond the stated range.

Questions about this item

What grid size must my existing suspension system have to accept the 15/16 in edge type?

The tiles fit a standard 15/16 in grid, so the T-bar profiles you already have should match that dimension exactly.

Can I keep my current lighting layout when I install tiles with a 0.9 light reflectance value?

A reflectance of 0.9 returns most incident light, so existing fixtures will appear brighter and you may be able to reduce lamp count.

How do I verify the 0.8 noise reduction coefficient is performing after installation?

Measure reverberation time in the finished room; a result near the 0.8 NRC rating confirms the tiles are absorbing sound as specified.
