Optima® for Prelude® XL Max®

Our Ceiling Selector can help you figure out what you need. After a few quick questions, we give you recommendations and can help you with your order and with installation.

It is recommended to change ceiling tiles out every 10 years. We have a 10-year warranty on most ceiling tiles. You can always patch and match a few tiles in the interim to transform any space or fix damages.

All of our mineral fiber ceiling tiles and panels can be painted with latex paints. The front and back of 24-in x 24-in and 24-in x 48-in panels should be painted.

PLEASE NOTE: Field painting will void the warranty. We cannot guarantee that the surface-burning characteristics, fire-resistance ratings, acoustical performance, dimensional stability/sag, or light reflectance will remain the same after repainting. TECTUM tiles can be painted up to 6 times without losing acoustical performance.

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.
