Armstrong black ceiling tiles are here and are formally known as Optra. Currently, this is the main black ceiling panel available from Armstrong. A
Another point worth noting is that Armstrong black ceiling tiles are compressed glass wool, not mineral fibre. Therefore when comparing to other black ceiling panels, Boral Sky Rock, would be the closest tile that comes to mind. The tile is incredibly lightweight, so it’s important to check with your local Armstrong rep when checking backloads.
Optra has an NRC rating of .90 which is excellent. In the 25mm version it’s .95, even better! Therefore, Optra would be excellent at helping to improve acoustics within a given space.
