Armstrong Ultima Ceiling Medallion 24 in

The Armstrong Ultima ceiling medallion measures 24 inches square with a 3/4 inch thickness. It is a mineral-fiber tile designed for standard 15/16 inch grid systems. The white finish provides a light reflectance of .9 for bright overhead spaces. Suitable for commercial and residential drop-ceiling installations.

Square Lay-In Edge and High NRC

The square lay-in edge allows the tile to sit flush within the grid for a clean ceiling plane. A noise reduction coefficient of .75 absorbs a significant portion of ambient sound. Ceiling attenuation class 35 limits sound transmission between adjacent rooms. These acoustic ratings help meet privacy and comfort requirements in open-plan areas.

Durable Mineral-Fiber Panel for Standard Grids

This tile suits projects needing sag resistance and a high recycled content of 77 percent. It resists bacteria, mold, mildew, scratches, soil and impact without special coatings. The fine texture maintains a uniform appearance across 48 square feet of coverage per carton. Buyers needing a tegular edge profile or a higher CAC rating should look at other options.

Questions about this item

Will the mineral fiber material need any special cleaning or replacement over time?

The tile resists bacteria, mildew, mold, sag, scratches and soil, so routine dusting or vacuuming is usually sufficient; no scheduled replacement is required.

What performance limit appears first when the tile is used continuously in a busy space?

With a Noise Reduction Coefficient of .75 and Ceiling Attenuation Class 35, the acoustic absorption ceiling is reached before any structural or thermal limit.

Does the tile add noticeable heat or noise when the HVAC runs all day?

The tile is passive — it generates no heat or noise of its own and operates within a 32 to 120 degree F range without degradation.
