The Noise Reduction Coefficient (NRC) value is the % of sound that can be absorbed by that tile. The best NRC ceiling tiles can absorb up to 95% of sound. Example: An NRC of .95 can absorb 95% of the sound that strikes the tiles surface.

The Ceiling Attenuation Class (CAC) value is the number of decibels the tile can block from leaving or entering a closed room when installed as a drop ceiling. The best ceiling tiles have a CAC of 45, which blocks 45 decibels of sound that hit the tiles surface.

Fire ratings refer to flame spread and smoke development. Ratings indicate how rapidly flame spreads on one surface as compared to another. The flame spread rating is broken into three categories: Class A, Class B and Class C. Class A products have a flame-spread of 25 or less, and smoke developed of 50 or less. Class C products have a flame-spread of 76-200, and smoke developed of 0-450. Class A products are appropriate in the majority of commercial applications and Class C products are appropriate in most residential applications.
