To find replacement tiles, you will need to find the item number of your current tiles. You can do that by removing the ceiling tile and flipping it over. Once you do that, locate the item # on the back of the tile. Enter the item number on our ceiling replacement page to get your match.

Dust and loose dirt may easily be removed by light brushing or with a vacuum cleaner. The best attachments to use are the ones for cleaning upholstery or walls. Make sure to clean in one direction only to prevent rubbing dust into the surface of the ceiling.

After loose dust has been removed, other marks can be easily erased with an ordinary eraser. Although, a fresh wall cleaner may be preferred. 

Mineral fiber ceilings may be cleaned with a moist cloth or a sponge dampened in water containing mild soap. The sponge should contain as little water as possible. After washing, the soapy film should be wiped off with a cloth or sponge slightly dampened in clean water.

Look for the disinfectable and cleanable icons for more information on your specific ceiling tile. You can also download our cleaning and disinfecting guidelines for more information.

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 GUARD means that the product is engineered and tested as part of a fire resistant system, which includes tile, grid and the structure itself. Please check local building codes requirements for your space. The following link will direct you to additional information and support for Armstrong's Fire Resistant ceiling systems. 

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.

Armstrong products come packaged in cartons to protect and maintain product integrity. Shipping individual or smaller groups of tiles or grid can impact the quality of tile or grid. Kanopi sells solely in carton format because of this reason. BONUS: It's always good to have extra material on hand for accidents or damage over time.
